Ingredients and Sauce Components

• 1 lb fully cooked shrimp, peeled, deveined, tails removed, chilled and patted dry
• 1 medium Roma tomato, seeded if very juicy and diced
• ½ English cucumber, diced
• ¼ cup red onion, finely diced
• ¼ cup fresh cilantro, chopped and divided
• 1 small jalapeño, seeded and finely chopped (optional)
• 1 ripe but firm avocado, diced
• Lime wedges for serving
• Tomato‑Lime Sauce: 1 cup plain tomato juice or Clamato
• Tomato‑Lime Sauce: ¼ cup ketchup (plus 1 tbsp reserved for adjustment)
• Tomato‑Lime Sauce: 2 tbsp fresh lime juice (plus more to taste)
• Tomato‑Lime Sauce: ¼ tsp black pepper
• Tomato‑Lime Sauce: fine salt, to taste

Mixing and Chilling Steps

1. Pat cooked shrimp completely dry with paper towels; leave small shrimp whole or cut larger shrimp into bite-sized pieces.
2. Seed (if very juicy) and dice the tomato; dice the cucumber; finely dice the red onion; chop most of the cilantro and reserve some for garnish; seed and finely chop jalapeño if using.
3. Whisk tomato juice or Clamato with 1/4 cup ketchup, 2 tablespoons fresh lime juice, and 1/4 teaspoon black pepper until smooth.

4. Taste the sauce and add the reserved 1 tablespoon ketchup and salt sparingly if needed.

   

5. Combine shrimp, diced tomato, cucumber, red onion, most cilantro, and jalapeño in a large bowl; pour the sauce over and gently fold to coat.
6. Cover and refrigerate about 20 minutes to let the flavors meld.
7. After chilling, gently stir and taste; adjust with a squeeze of lime or a pinch of salt if desired.
8. Carefully fold in diced avocado at the end, taking care not to mash it.
9. Divide the shrimp cocktail among cups, spoon any extra sauce on top, and sprinkle with the reserved cilantro.

Tips for Best Texture and Flavor

• Make sure the shrimp is nicely dried before mixing so your sauce stays thick and not watery.
• If you’re using large shrimp, cut them into pieces that are all about the same size. It makes every bite balanced and enjoyable.
• Hold back some cilantro and avocado until the very end to preserve their fresh color and crisp texture.
• Before you season with salt, taste your tomato juice or Clamato since some store-bought versions can be salty already.
• If you plan to make the cocktail ahead, keep the avocado separate until just before serving to prevent browning and sogginess.

Easy Swaps and Flavor Twists

• Seafood swap: Try using cooked crab, lobster, or a mix of shrimp and imitation crab for a new seafood twist.
• Spice it up: Add a few dashes of your favorite hot sauce or include the jalapeño seeds if you like heat—if you crave a bolder bite, try Fiery Cajun Shrimp Stuffed Jalapeños.
• Fruity touch: Fold in diced mango or pineapple for a subtle sweet‑tangy pop against the savory base.
• Dairy option: Stir in a spoonful of sour cream or Mexican crema for an added creaminess boost.
• Herb swap: If cilantro isn’t your thing, try fresh parsley for a milder, different herbal note.

Storing and Make-Ahead Advice

You can store any leftover Mexican shrimp cocktail in an airtight container in the fridge for up to 24 hours. To keep everything fresh and the avocado’s texture intact, store the diced avocado separately and add it just before serving. Avoid freezing the assembled cocktail since the avocado and crisp veggies won’t hold up well. Also, the tomato‑lime sauce can be made a day or two in advance and kept chilled until you’re ready to mix. For another chilled, make-ahead appetizer that holds well in the fridge, try this crab dip.

Common Questions and Answers

Can I use raw shrimp? This recipe is designed for fully cooked shrimp, so raw shrimp isn’t recommended unless you cook it first and adjust the timing and safety steps.

Can I use frozen shrimp? Absolutely! Just make sure to thaw fully in the fridge and pat dry before using to keep everything from getting watery.

What can I substitute for Clamato? Plain tomato juice works just fine if you don’t have Clamato. The Clamato adds a slightly salty, savory touch but either will taste great.

How long can I make this ahead? You can prep the sauce and chop everything up to a day ahead, but hold off mixing in the avocado and shrimp with the sauce until just before serving for the best texture. It’s best to enjoy this dish within 24 hours.

Is this spicy? The heat depends on whether you include the jalapeño and keep the seeds. You can easily adjust the spice level to suit your family’s taste. For a milder, fruit-forward twist, top the cups with our mango salsa recipe.

Can I scale this up for a party? Definitely! Just multiply the ingredients and serve in bigger bowls or set out individual cups. Keep avocado separate until serving if you’re prepping in advance. For a crowd-pleasing main, pair them with fish tacos with cabbage slaw.
