Spicy Watermelon Shrimp Ceviche Cups are my warm weather secret for easy entertaining These bright little lettuce cups pack cool juicy watermelon with tender shrimp and citrus for that irresistible balance of sweet heat and tangy crunch Every time I bring these out for friends the whole platter disappears within minutes and they have even become a summer birthday tradition at my house
I first threw these together on a steamy July day when I wanted something light but satisfying Now my family requests them for poolside lunches and neighbors ask for the recipe whenever I serve them
Ingredients
- Medium shrimp: fresh or frozen for tender protein and quick cooking Look for peeled and deveined for ease
- Lime juice: freshly squeezed for bright acidity and classic ceviche flavor Choose limes that feel heavy for their size
- Seedless watermelon: small diced for sweetness and crisp texture Go for deep red flesh and minimal white lines
- Red onion: finely diced for sharp bite and color Use a firm onion and soak in water if very pungent
- Jalapeño: finely diced for heat with seeds removed for lower spiciness Select glossy and unblemished peppers
- Cucumber: peeled seeded and diced for cooling crunch Pick firm cucumbers with no soft spots
- Avocado: diced for creaminess and richness Hass avocados with a slight give at the stem end work best
- Fresh cilantro: chopped for herbal brightness Leaves should look perky and green
- Butter lettuce or small gem lettuce leaves: for cup bases Crisp leaves help everything hold together
- Sea salt: enhances all flavors Choose fine flakes for easy sprinkling
- Freshly ground black pepper: for warmth and depth
- Extra-virgin olive oil: to round out flavors and add a silky finish Use a fruity and peppery oil if possible
- Hot sauce: optional for an extra punch Bottle brands or homemade both work well
Step-by-Step Instructions
- Prepare the Ice Bath:
- Fill a medium bowl with cold water and plenty of ice The ice bath instantly stops the shrimp from overcooking and keeps them tender
- Cook the Shrimp:
- Bring a medium saucepan of salted water to a boil Add the shrimp and cook for one to two minutes They should turn pink and opaque immediately Chill them in the ice bath to lock in their juiciness
- Chop the Shrimp:
- Once the shrimp have cooled completely in the ice bath drain them well and chop them into bite sized pieces for even marinating
- Marinate with Lime Juice:
- In a nonmetallic mixing bowl combine the chopped shrimp with all the freshly squeezed lime juice Let it chill in the refrigerator for ten minutes so the flavors meld and the shrimp takes on a tangy brightness
- Drain and Reserve Juice:
- After marinating drain nearly all the lime juice from the bowl leaving a couple of tablespoons behind This helps balance tartness and keeps the ceviche juicy without being watery
- Combine Fruits Veggies and Mix:
- Add the diced watermelon cucumber avocado onion jalapeño and cilantro into the bowl with the shrimp Season with sea salt black pepper and a drizzle of olive oil plus hot sauce if you want a spicy kick Gently fold everything together so the avocado stays intact
- Assemble into Lettuce Cups:
- Carefully spoon the ceviche mixture into the lettuce leaves making sure each cup gets a little of everything Arrange on a platter and serve at once Garnish with extra cilantro for a fresh pop

Watermelon is my secret weapon in this dish It brings not just juiciness but a sweet contrast that makes the shrimp shine The first time I made these for my kids was a riot of laughter in the kitchen as they helped scoop the filling into the lettuce cups Little hands made for slightly messy but truly joyful bites we still laugh about
Storage Tips
If you have leftovers refrigerate the shrimp watermelon mixture without the lettuce in an airtight container for up to one day The acidity keeps the flavor vibrant but avocado may soften slightly Wait to assemble into lettuce cups until just before serving so the leaves stay crisp
Ingredient Substitutions
Swap the shrimp for cooked bay scallops or a mild white fish like halibut for a twist Mango or pineapple can stand in for watermelon if you want extra sweetness For extra heat use a serrano pepper instead of jalapeño If cilantro isn’t your favorite try fresh mint or flat leaf parsley
Serving Suggestions
Set out with a platter of tortilla or plantain chips alongside for scooping Serve these ceviche cups as a starter for grilled fish tacos or with a big jug of iced agua fresca For fancier occasions garnish each cup with a thin slice of jalapeño or delicate microgreens
Cultural Notes
Ceviche has roots along the Pacific coast from Peru to Mexico Traditionally seafood is “cooked” in citrus rather than heat This fusion take draws on both Latin American and Caribbean favorites by combining shrimp and fresh tropical fruit served in crisp lettuce boats for a party-perfect update
