Full Recipe (Ingredients + Instructions)

Ingredients 🍤

For the Shrimp Ceviche

  • 1½ lbs raw shrimp, peeled and deveined
  • ¾ cup fresh lime juice
  • ¼ cup fresh lemon juice
  • 3 Roma tomatoes, seeded and diced
  • 1 large cucumber, peeled, seeded, and diced
  • ½ medium red onion, finely diced
  • 1–2 jalapeños, finely chopped
  • 1 serrano pepper, finely chopped, optional
  • ½ cup fresh cilantro, chopped
  • 1 large avocado, diced
  • ½ cup Clamato or tomato juice, optional
  • 1 tablespoon extra-virgin olive oil
  • ½ teaspoon Mexican oregano, optional
  • Salt and black pepper, to taste

For Serving 🌮

  • 10–12 crispy tostada shells
  • Avocado slices
  • Lime wedges
  • Hot sauce
  • Salsa
  • Tajín
  • Extra cilantro

Step 1: Prepare the Shrimp 🍤

For the safest and most reliable homemade version, quickly cook the shrimp before marinating.

Bring a pot of lightly salted water to a boil.

Add the shrimp and cook for approximately 2–3 minutes, just until opaque and cooked through.

Shrimp should reach 145°F (63°C).

Immediately transfer them to an ice bath.

Once completely cooled, drain well and chop into bite-sized pieces.

Important Ceviche Tip 🍋

Traditional ceviche may use citrus juice to change the texture and appearance of raw seafood, but acid isn’t the same as cooking with heat and doesn’t reliably eliminate all foodborne pathogens. Briefly cooking the shrimp first gives you a safer ceviche while keeping that fresh citrus flavor.

Step 2: Marinate in Fresh Citrus 🍋

Place the cooled chopped shrimp in a large glass or nonreactive bowl.

Pour over:

  • Fresh lime juice
  • Fresh lemon juice

Stir well.

Cover and refrigerate for approximately 20–30 minutes.

That gives the shrimp plenty of time to soak up all that fresh citrus flavor.

Step 3: Prepare the Fresh Vegetables 🍅🥒

While the shrimp marinates, dice:

🍅 Roma tomatoes
🥒 Cucumber
🧅 Red onion
🌶️ Jalapeño
🌶️ Serrano, if using
🌿 Cilantro

Keep everything fairly small and uniform.

You want a little shrimp and every vegetable in each tostada bite.

Step 4: Mix the Ceviche 🌶️🍤

Add the tomatoes, cucumber, onion, jalapeño, serrano, and cilantro to the marinated shrimp.

Pour in the Clamato or tomato juice if using.

Add:

  • Olive oil
  • Mexican oregano
  • Salt
  • Black pepper

Mix gently.

Taste and adjust the lime, chile, and salt.

Want It Spicier? 🔥

Leave some seeds in the jalapeño or add another serrano.

Step 5: Chill It ❄️

Cover the ceviche and refrigerate for another:

20–30 minutes

This gives the flavors time to come together.

You want it COLD, FRESH, and ZESTY! 🍋🌶️

Step 6: Add the Avocado 🥑

Immediately before serving, gently fold in the diced avocado.

Don’t add it too early because it can become soft and lose its beautiful fresh appearance.

Add one final squeeze of lime.

Homemade Crispy Tostadas 🌽🔥

Want to make your own instead of using packaged tostadas?

You’ll Need

  • 10–12 corn tortillas
  • Vegetable oil
  • Fine salt

Heat about ½ inch of oil in a skillet to approximately 350°F (175°C).

Fry each tortilla until crisp and golden, turning once.

Transfer to a wire rack or paper towels.

Sprinkle lightly with salt while still hot.

Oven Version

Brush both sides of the corn tortillas lightly with oil.

Bake at 425°F (220°C) for approximately 8–12 minutes, flipping halfway through, until golden and crisp.

Step 7: Build the Ceviche Tostadas 🌮🍤😍

Take one crispy tostada.

Add a generous spoonful of cold Mexican ceviche.

Make sure you get:

🍤 Shrimp
🍅 Tomato
🥒 Cucumber
🌶️ Jalapeño
🥑 Avocado
🌿 Cilantro

Drizzle with hot sauce and finish with a squeeze of fresh lime.

BIG TIP

Use a slotted spoon when piling ceviche onto tostadas.

You’ll get all those juicy ingredients without immediately turning your crispy tostada soggy.

Spicy Ceviche Tostadas 🔥🌶️

For the people who want HEAT, mix in:

  • 2 serrano peppers
  • 1 jalapeño
  • A few drops of habanero hot sauce
  • Tajín
  • Extra lime

Top each tostada with thin avocado slices to balance the heat.

Spicy + creamy + crunchy = SO GOOD! 🔥🥑

Mango Shrimp Ceviche 🥭🍤

Add 1 cup finely diced ripe mango to the finished ceviche.

The sweetness of mango works beautifully with lime, chile, and shrimp.

For even more tropical flavor, add a little diced pineapple.

Avocado Ceviche Tostadas 🥑❤️

Spread a thin layer of mashed avocado or guacamole over each tostada before adding the ceviche.

Then pile the shrimp ceviche on top.

Finish with:

  • Queso fresco, optional
  • Tajín
  • Cilantro
  • Hot sauce
  • Lime

That creamy avocado layer underneath the cold ceviche is DELICIOUS.

Extra Recipe Tips & Variations ✨

🐟 Fish Ceviche

Use a firm white fish suitable for your preparation, but for a home recipe where food safety is the priority, start with properly cooked seafood.

🦀 Shrimp & Crab

Add cooked lump crab meat for a loaded seafood version.

🥭 Mango

Add mango for a sweet-and-spicy variation.

🍍 Pineapple

Fresh pineapple gives the ceviche a tropical twist.

🌶️ Extra Spicy

🥑 Extra Avocado

Double it. Nobody is going to complain. 😂

🍅 Clamato Style

Flavor Upgrades / Secret Tips 🔥

✅ Use freshly squeezed lime juice, not bottled, when possible.

✅ Chill all your ingredients before assembling.

✅ Add avocado immediately before serving.

✅ Use a slotted spoon to protect those crunchy tostadas.

✅ Keep the ceviche cold until you’re ready to eat.

✅ Don’t assemble tostadas in advance. Ceviche + tostada happens at the LAST MINUTE!

Storage & Meal Prep Tips 🥡

Ceviche is best enjoyed fresh and cold.

Store prepared shrimp ceviche in a tightly covered container in the refrigerator and use within 1–2 days.

Keep avocado separate if preparing ahead.

Keep tostadas completely separate at room temperature in an airtight container so they stay crisp.

Don’t leave seafood ceviche sitting at room temperature for extended periods.

Frequently Asked Questions (Q&A)

Q: Can lime juice cook raw shrimp?
A: Citrus acid changes the proteins and can make shrimp look and feel cooked, but it doesn’t provide the same pathogen reduction as heat. For a safer homemade version, briefly cook the shrimp first and then marinate it in citrus.

Q: Can I make ceviche the night before?
A: You can prepare some components ahead, but ceviche has its best texture when made fresh. Add avocado only shortly before serving.

Q: Why did my tostadas become soggy?
A: Too much ceviche liquid probably soaked into them. Use a slotted spoon and assemble immediately before eating.

Q: Can I use frozen shrimp?
A: Absolutely. Thaw completely in the refrigerator, then cook, chill, and proceed with the recipe.

Q: What hot sauce works with ceviche?
A: A bright Mexican-style hot sauce or chile de árbol salsa pairs beautifully with the citrus and shrimp.

Q: Can I leave out the Clamato?
A: Definitely. It’s optional. Without it, you’ll have a brighter, more citrus-forward ceviche.
