Shrimp ceviche (seh-VEE-chay) is usually eaten in Mexico piled on a crisp corn tostada: small pieces of shrimp turned opaque in lime juice, tossed with tomato, cucumber, red onion, green chile and cilantro, with avocado on top. It is the chopped, milder cousin of shrimp aguachile. Two numbers make it work, 20 minutes in lime for pieces about ½ inch (1 cm) across, and one decision changes who can eat it: raw and lime-cured, or blanched for a minute first. Lime juice firms shrimp up but does not make it safe the way heat does, so both versions are here, with amounts from a small table up to 20 people, what it costs in the US and how long it keeps.
Is shrimp ceviche worth making, and who is it for?
How do you make shrimp ceviche? Cut peeled raw shrimp into ½-inch (1 cm) pieces, salt them and cover with fresh lime juice in the fridge for about 20 minutes, until opaque to the center. Pour off half the juice and fold in seeded tomato and cucumber, red onion, serrano chile and cilantro, then avocado at the end. For anyone who should not eat raw seafood, blanch the shrimp 1-2 minutes first. Ready in 45 minutes for 4 servings.
Yes, if you like bright, cold, sour food. It takes 45 minutes, about 32 of them hands-on, with no oven, and 1.1 lb (500 g) of peeled shrimp makes 4 appetizer servings or 8 loaded tostadas. It reads as fancy and costs mostly whatever the shrimp costs.
Good for: a hot-weather lunch, a game-day spread with chips, Lent, or a cold seafood table next to a Mexican shrimp cocktail. It scales without extra work: for 20 you make the recipe four times over.
Not for, as written: raw, it is not for anyone pregnant, toddlers, older adults or people with weakened immune systems; the blanched version is the same recipe with one extra step. Not for shellfish allergies. And not a make-the-night-before dish, because shrimp keeps firming up in lime.
Honest difficulty: easy. Nothing here needs knife skills. What goes wrong is the clock (an hour in lime “to be safe”) and water from the tomato and cucumber.
Ingredients, and what to buy in a US or UK supermarket
Amounts for 4 are in the recipe card: 1.1 lb (500 g) shrimp, ¾ cup (180 ml) lime juice, 9 oz (250 g) tomato, 7 oz (200 g) cucumber and 1 avocado. The shrimp is the purchase that matters.
Which shrimp to buy for ceviche
Since it gets chopped, size does not matter: 31/40 or 41/50 count (pieces per pound) is cheaper than jumbo and looks the same in ½-inch pieces.
- For raw ceviche, I buy a bag of frozen raw shrimp, sealed, with no frost or ice crystals inside, and thaw it overnight in the fridge. The FDA explains that freezing kills parasites that may be in seafood but does not kill all harmful germs, so frozen is the better buy, not a sterilized one.
- “Fresh” at the seafood counter is often previously frozen and thawed in the store. Ask. It should smell like the sea, never of ammonia.
- Read the label. Shrimp sold with added sodium tripolyphosphate or “to retain moisture” turns slightly spongy and saltier. The bag that lists only shrimp (and maybe salt) is the one.
- Precooked (the pink ring from the seafood case) works for the cooked version and saves 10 minutes, but tastes the least of the sea. 15 oz (420 g) of precooked equals 1.1 lb (500 g) raw, because shrimp loses about 16% of its weight when cooked.
In the UK what Americans call shrimp is sold as king prawns or prawns; frozen raw king prawns from the supermarket freezer aisle are the right buy. UK “brown shrimp” are a different, tiny animal.
Swaps for limes, tomatoes and chiles
| Ingredient | US supermarket | UK supermarket | What changes |
|---|---|---|---|
| Lime | Regular (Persian) limes, about 3 tbsp juice each | Limes, same variety | Key limes are more aromatic; you need about twice as many |
| Tomato | Roma (plum) | Plum or vine tomatoes | Seed them either way; beefsteak tomatoes add water |
| Cucumber | English (hothouse) or small regular | Standard UK cucumber | Fewer seeds means less liquid; scoop out what is there |
| Serrano chile | Most large grocery stores | Rare; use green finger chillies | Jalapeños are milder: 2,500-5,000 Scoville units vs 5,000-15,000 for serrano (NDSU Extension) |
| Red onion | Red onion | Red onion | White onion is sharper; soak 5 minutes in ice water |
| Cilantro | Cilantro | Fresh coriander | Same herb, different name |
Bottled lime juice is the one swap I would not make. It tastes cooked and flattens the whole bowl.
Tools
A sharp knife, a cutting board, a glass or ceramic bowl and a colander. Skip aluminum bowls, which react with the acid and taste metallic. For the cooked version, a pot and a bowl of ice water.
Make-ahead plan and how to tell it’s ready
45 minutes on the clock and about 32 of work. The trick is chopping the vegetables while the shrimp cures, not before or after.
What you can do ahead: move frozen shrimp to the fridge the night before. Up to 4 hours ahead, chop the onion, chile and cilantro and keep them covered in the fridge. Cut the tomato and cucumber just before, since cut, they leak. For the cooked version, blanch, chill and chop the shrimp the day before; on the day it only needs 10 minutes in lime.
Signs it’s going right:
- Shrimp in lime → at 10 minutes the edges are white and the middle is still gray; at 15-20, a halved piece shows no gray.
- Vegetables → after 8 minutes salted in the colander, 2 or 3 tablespoons of pink liquid sit underneath. That was headed for your ceviche.
- The mix → it glistens but does not float. If more than a finger’s width of juice runs when you tilt the bowl, drain some more.
- Seasoning → taste it on a tostada or chip, not off a spoon. The plain tostada wants the ceviche a touch saltier.
How long to marinate shrimp in lime juice for ceviche
Give it 20 minutes in the fridge for ½-inch (1 cm) pieces, and start cutting one open at the 15-minute mark. Rick Bayless gives his green shrimp ceviche, cut just under ½ inch, 30 minutes; Erin Clarke of Well Plated gives whole raw shrimp 1 to 2 hours. Bigger pieces need longer, and past the point the shrimp does not get safer, only tighter.
How to keep shrimp ceviche from getting watery
Watery ceviche has three causes, and each has a fix:
- Tomato and cucumber seeds. Scoop them out with a teaspoon. They hold most of the water.
- Salt on cut vegetables. It pulls liquid out in minutes, so salt them first in the colander for 8 minutes and throw that liquid away.
- Too much lime. ¾ cup (180 ml) covers the shrimp for curing; it is too much to eat. Pour off half before mixing.
Avocado goes in last, in firm cubes. Added early, it smears and clouds the juice.
Cooked shrimp ceviche, step by step
Bring 6 cups (1.5 liters) of water and 1 tablespoon of salt to a boil and set up a bowl of ice water. Add the peeled, whole shrimp and count 1 to 2 minutes from when it returns to a gentle boil, until opaque and curled into a C. Shrimp is done when the flesh is firm, pearly and opaque, according to the FDA, which puts most seafood at 145°F (63°C). Into the ice for 5 minutes, pat dry and chop. Since there is nothing left to cure, 6 tablespoons (90 ml) of lime and 10 minutes in the fridge are enough, and nothing gets poured off. Bayless does it the same way for his shrimp and scallop ceviche tostadas: about 2 minutes at a simmer, ice water, ½-inch pieces.
Is shrimp ceviche safe? Lime juice, heat level, kids and allergens
Does lime juice cook shrimp? No, not the way heat does. The acid changes the surface proteins, which is why shrimp turns opaque and firm, and it does knock down some bacteria. A 2013 Rutgers University study in the Journal of Food Protection found that lime juice took Vibrio parahaemolyticus below detectable levels within 30 minutes, while Salmonella on the same fish dropped only 1 to 2 log units. Canada’s National Collaborating Centre for Environmental Health (NCCEH) put it plainly in a 2019 review: the seafood may look cooked, but it has not been, and citrus does not inactivate every pathogen. The same review lists a 2016 Vibrio cholerae outbreak in Minnesota, 6 people sickened by ceviche made with raw shrimp and raw oysters.
Who should skip it raw: the FDA advises pregnant women, young children, older adults and people with weakened immune systems to avoid raw or undercooked seafood, naming ceviche specifically. For them, the blanched version, 1-2 minutes to 145°F (63°C).
Common mistakes:
- Soupy bowl → seeds left in, salt added in the bowl instead of the colander, or all the lime kept in.
- Tough, squeaky shrimp → too long in lime. If you need to hold it, drain the lime on time and keep the shrimp separate.
- Some pieces raw, some overdone → uneven sizes. Cut everything to ½ inch (1 cm).
- Bitter or “cooked” taste → bottled juice, or limes squeezed so hard the pith gets in.
- Mushy avocado → added too early or too ripe. Pick a Hass that gives slightly.
- Rubbery cooked shrimp → more than 2 minutes in the water, or no ice bath.
Heat: 3 out of 5 with 2 serranos, seeds in. One seeded serrano drops it to 1, and hot sauce on the table lets everyone go up from there.
Kids: the cooked version with no chile and big avocado cubes usually goes down well on a tostada. Do not give raw ceviche to small children.
Allergens: shellfish (crustaceans), one of the major allergens in the US and the UK. The recipe itself has no gluten, dairy or egg; check tostada and cracker labels for wheat if you are cooking for someone with celiac disease.
Which shrimp ceviche to make
- Short on time → chopped precooked shrimp, 10 minutes in lime: on the table in 25 minutes.
- Someone can’t eat raw → make the blanched version for everyone. One bowl, no labels.
- For a party → use the table below and blanch the shrimp the day before.
- Lighter → skip the avocado: about 140 kcal and 1 g fat per serving instead of 203 and 7. Serve with cucumber rounds instead of fried tostadas.
- Vegetarian → 14 oz (400 g) sliced hearts of palm instead of shrimp, no curing, just the vegetables and 6 tbsp (90 ml) lime. Same dressing, no sea.
- With mango → 1½ firm mangoes, diced, per 1.1 lb (500 g) cooked shrimp, the ratio in a Lent recipe from Mexico’s ADN40. Underripe-ish fruit holds its shape.
- Ecuadorian style → shrimp dipped for seconds in a stock made from its shells, lime with orange juice, sliced red onion and a little ketchup, with avocado on the side.
- Rather use fish? → Mexican fish ceviche is the same idea with ¾-inch (1.5 cm) cubes and 20-30 minutes in lime.
Scaling for 4 or for 20
I plan on 4.5 oz (125 g) of peeled shrimp per person when ceviche is the main snack and 3.5 oz (100 g) at a party with other food.
| Ingredient | 4 people | 20 people |
|---|---|---|
| Raw peeled shrimp | 1.1 lb (500 g) | 4.4 lb (2 kg) |
| Lime juice | ¾ cup (180 ml), 4-5 limes | 3 cups (720 ml), 16-18 limes |
| Fine salt | 1 tsp | 4 tsp |
| Plum tomatoes | 9 oz (250 g), 2 | 2.2 lb (1 kg), 8 |
| Cucumber | 7 oz (200 g) | 1.75 lb (800 g) |
| Red onion | 3 oz (80 g), ½ | 11 oz (320 g), 2 |
| Serrano chiles | 2 | 4-6, plus hot sauce |
| Cilantro | 1 cup (15 g) | 4 cups (60 g), 2 bunches |
| Hass avocados | 1 | 4 |
| Tostadas | 8 | 40 |
For 20, cure the shrimp in two shallow glass dishes, not one deep bowl: in a thin layer the lime reaches every piece at once. Put out half, keep half in the fridge, and swap when the first is gone, since it should not sit out more than 2 hours.
What shrimp ceviche costs in the US
Using the average US supermarket shrimp price Expana reported for early 2026, $9.65 per pound, plus USDA retail produce prices from October 2026, four servings come to about $16.87, or $4.22 each, before tostadas.
Yield: 4 servings of about 10.5 oz (300 g), or 8 loaded tostadas; 5 servings as part of a bigger spread.
What drives the cost: the shrimp, at 63%. Two ways to cut it without anyone noticing: a smaller count (it is chopped anyway) and frozen on sale, which is also the better choice for raw ceviche. I could not find an official UK prawn price, so there is no pound figure here.
Serving, storage and leftovers
What it tastes like: sour and cold, with tender shrimp, crunchy cucumber and onion, green heat from the serrano and cool, fatty avocado against the lime. Blanched shrimp is a little firmer and less silky; the dressing is the same.
How to serve it: piled on corn tostadas with a few drops of hot sauce, in a glass with saltines, or in a bowl with tortilla chips. For plantain fans, crisp twice-fried plantains hold it without breaking. Put out guacamole and a bowl of pico de gallo alongside, and pour a cold michelada, or a cucumber lime agua fresca for anyone skipping the beer.
Fridge: raw, eat it the same day; the lime keeps working and by the next day the shrimp is tight and the avocado brown. Cooked, it keeps up to 2 days at 40°F (4°C) or below in a sealed container. USDA FSIS allows 3 to 4 days for cooked leftovers, but the vegetables go limp after day two. If you expect leftovers, keep the avocado out.
On the table: the FDA’s limit is 2 hours, or 1 hour above 90°F (32°C). For a long party, nest the bowl in a bigger one filled with ice.
Freezer: no. Tomato, cucumber and avocado collapse when thawed. Freeze raw shrimp before you make ceviche, never the ceviche.
Shrimp ceviche FAQ
Is shrimp ceviche safe to eat? Good frozen shrimp, kept cold and eaten fresh, lowers the risk for healthy adults, but lime juice does not kill every germ. Pregnant women, young children, older adults and immunocompromised people should eat the blanched version.
How long should shrimp sit in lime juice for ceviche? About 20 minutes in the fridge for ½-inch (1 cm) pieces, until a halved piece has no gray center. Cooked shrimp needs only 10.
Can I use frozen shrimp for ceviche? Yes, and for raw ceviche it is the better buy. Thaw it overnight in the fridge or sealed in cold water, never on the counter.
Can I use cooked shrimp? Yes. Blanch raw shrimp 1-2 minutes or use precooked, chop it, and give it 10 minutes in lime. It is firmer and less silky.
Can you eat shrimp ceviche while pregnant? Not raw; the FDA advises against raw seafood in pregnancy. Blanched to 145°F (63°C) first, yes.
How long does shrimp ceviche last in the fridge? Raw, same day. Cooked, up to 2 days sealed at 40°F (4°C) or below. It does not freeze.
How much shrimp do I need per person? 4.5 oz (125 g) peeled shrimp as the main appetizer, 3.5 oz (100 g) at a party. For 20 people, 4.4 lb (2 kg).
Is shrimp ceviche healthy? It is lean and high in protein: 203 kcal and 27 g protein per serving, with most of the fat from avocado. Sodium is around 741 mg, mostly from the salt you add.
What’s the difference between shrimp ceviche and aguachile? Aguachile uses whole butterflied shrimp in a blended green chile-lime sauce and is eaten within about a quarter of an hour. Ceviche uses chopped shrimp with more vegetables and about 20 minutes in lime.
Nutrition per serving
Per serving (about 10.5 oz / 300 g, without tostadas), worked out ingredient by ingredient from USDA FoodData Central (SR Legacy) with this recipe’s amounts, counting half the lime juice (the half that stays in the bowl) and all the salt:
- Calories: 203 kcal
- Protein: 27 g
- Carbohydrates: 12 g
- Fat: 7 g (1 g saturated)
- Fiber: 4 g
- Sugars: 4 g
- Sodium: 741 mg
Raw shrimp has 85 kcal and 20.1 g protein per 100 g (3.5 oz), and the avocado is nearly all the fat. Some of the salt leaves with the drained vegetable liquid and lime, so you eat a bit less sodium than listed. Tostadas add up fast: about 58 kcal and 81 mg sodium per 12 g shell.
My kitchen rule for shrimp ceviche is short: chop it evenly and set a timer for 20 minutes, not “a while.” When my son Dylan eats with us, I blanch all of the shrimp for a minute and make one bowl for the whole table, so nobody has to ask which one is safe with a tostada already in hand. Josnaisis.
