Easy Keto Ceviche Recipe

Ceviche is a refreshing seafood appetizer that’s naturally low-carb. Fresh shrimp, lime juice, avocado, and simple vegetables make for an impressive, restaurant-quality dish that comes together in 15 minutes.

Why Ceviche is Perfect for Keto

• Naturally low-carb: Seafood and vegetables have minimal carbs
• High protein: Shrimp is pure protein (1g carb per 3 oz serving)
• Fresh and light: No heavy sauces or creams
• Impressive: Tastes restaurant-quality but takes 15 minutes
• No cooking required: The lime juice “cooks” the shrimp

Ingredients (Serves 4)

• 1 pound large shrimp, peeled and deveined
• 1 cup fresh lime juice (about 6-8 limes)
• 1/2 cup lime juice (reserve for serving)
• 1/2 red onion, finely diced
• 2 jalapeños, minced (seeds removed for less heat)
• 1 cup diced cucumber
• 1/2 cup diced bell pepper (red or yellow)
• 2 avocados, diced
• 1/4 cup fresh cilantro, chopped
• 2 tablespoons olive oil
• Sea salt and black pepper to taste
• Optional: hot sauce, cotija cheese

Step-by-Step Instructions

Step 1: Prepare Shrimp (2 minutes)

Cut shrimp into bite-sized pieces (quarters or halves). Place in a glass bowl.

Step 2: Cure with Lime (10 minutes)

Pour 1 cup fresh lime juice over the shrimp. The acid will “cook” the shrimp, turning it opaque and white (about 10 minutes). Stir occasionally. When the shrimp is white throughout, it’s done.

Step 3: Add Vegetables (2 minutes)

Drain shrimp, reserving a small amount of lime juice. Add red onion, jalapeños, cucumber, and bell pepper. Mix gently.

Step 4: Add Finishing Touches (1 minute)

Gently fold in diced avocado and fresh cilantro. Add olive oil, remaining lime juice, salt, and pepper to taste.

Step 5: Chill and Serve (Optional)

Serve immediately or chill for up to 2 hours. Don’t make it too far in advance or the avocado will brown.

Nutritional Information (Per Serving)

Variations

Fish Ceviche

Use diced sea bass, mahi-mahi, or other firm white fish instead of shrimp. Cure for the same 10 minutes.

Scallop Ceviche

Bay scallops work beautifully. Cut into smaller pieces and cure for 8 minutes instead of 10.

Mixed Seafood

Combine shrimp, fish, and scallops for variety.

Spicy Version

Double the jalapeños or add habanero peppers. Use hot sauce instead of mild salsa.

Creamy Lime Dressing (Optional)

Mix sour cream with lime juice and cilantro for a creamy topping. Adds 1g carb per tablespoon.

Pro Tips

Use Sushi-Grade Shrimp

Some recipes call for pre-cooked shrimp. That works, but fresh (uncooked) shrimp has better texture when cured in lime juice.

Don’t Over-Cure

10 minutes is perfect. Over 15 minutes and the shrimp becomes rubbery.

Prep Everything in Advance

Dice all vegetables ahead of time. Assemble the ceviche just before serving to keep avocado fresh.

Serve in Lettuce Cups

Use butter lettuce or iceberg lettuce as edible “cups” for a fun presentation.

Serving Suggestions

• As an appetizer in lettuce cups
• In avocado halves (stuff the ceviche into hollowed avocado halves)
• With cucumber slices as crackers
• In a bowl with lime tortilla chips (if you want added carbs)
• Over a bed of greens as a salad

Storage

Refrigerator: Store in an airtight container for up to 2 days. The longer it sits, the more the avocado oxidizes.

Best served: Within 4 hours of assembly for the freshest taste.

FAQ

Is raw shrimp safe in ceviche?

Yes, as long as it’s sushi-grade (sushi-quality). The acid in lime juice technically doesn’t kill bacteria, but the curing process does denature proteins safely. Buy from a reputable source.

Can I use frozen shrimp?

Yes, thaw completely first. Frozen shrimp works fine—it’s still technically “raw” when thawed and can be cured just like fresh.

How much lime juice do I really need?

At least 1 cup for the curing process. More is fine—you’ll just have a citrusy ceviche.

Can I make this dairy-free?

Yes—ceviche is naturally dairy-free as written. It’s already vegan-friendly if you remove the shrimp.

Final Thoughts

Ceviche is the perfect keto appetizer or light meal. It’s fresh, impressive, incredibly low-carb, and takes just 15 minutes. Impress friends at your next dinner party with this restaurant-quality dish.
