These Ceviche Cucumber Cups combine fresh raw fish or shellfish with lime juice, red onion, cilantro and a touch of jalapeño for brightness and texture. Naturally gluten-free, paleo-friendly and low in carbohydrates, they make an elegant, light appetizer for gatherings or a refreshing starter for warm weather meals.
Ceviche Cucumber Cups
Ceviche is a classic dish in which citrus—most commonly lime juice—”cooks” raw seafood by changing the protein structure, producing an opaque, firm texture similar to cooked fish. The result is bright, tangy and refreshing. This version nests the ceviche inside hollowed cucumber rounds for an attractive, low-carb presentation that’s simple to prepare yet impressive to serve.
I developed this recipe after attending a class demonstration at a professional culinary school, where scallop ceviche was on the menu. For this recipe I used fresh striped bass, but you can use almost any firm, very fresh ocean fish or shellfish—shrimp, scallops or a firm white fish all work well. The key is freshness: ideally, buy fish that has been handled and chilled properly and, when possible, was caught recently.
For best flavor and texture, prepare the cucumber cups and the vegetables ahead, but add the lime juice to the fish and allow it to marinate no more than one to two hours before serving. The acid does the “cooking,” and over-marinating can make the seafood overly firm. Serve immediately for the brightest taste.
This appetizer is adaptable: adjust the jalapeño for heat, use less or more onion to suit your taste, or add a tiny dollop of sour cream or avocado to each cup for a creamy contrast. It’s an excellent choice for holiday gatherings, cocktail parties, or as a light course during a multi-course meal.

Ceviche Cucumber Cups — Recipe
Yield: 15 servings (about 2 cups per serving)
Serving size: 2 cucumber cups each
Ingredients
- 8 oz fresh raw fish fillet such as striped bass, finely diced
- 1 medium seeded tomato, finely diced
- 1 tbsp chopped fresh cilantro
- 1 tbsp minced red onion
- 1/2 jalapeño, minced (adjust for heat)
- 1/4 yellow bell pepper, finely diced
- 1/2 tbsp olive oil
- 3 drops Tabasco or a few drops of hot sauce, to taste
- 3 tbsp fresh lime juice (from 1–2 limes)
- Kosher salt and freshly ground black pepper, to taste
- 2 large cucumbers, about thirty 1/2-inch-thick slices
- Fresh cilantro leaves for garnish (optional)
Instructions
- In a medium bowl, combine the diced fish, tomato, red onion, chopped cilantro, minced jalapeño and diced bell pepper.
- Add the olive oil and Tabasco (or hot sauce) and toss gently to combine.
- Pour in the fresh lime juice and toss again to coat the fish evenly. Season with kosher salt and freshly ground black pepper.
- Cover and refrigerate to marinate at least 1 hour, stirring occasionally. Marinating time depends on the size of the fish cubes—look for a change in the flesh from translucent to a more solid, opaque appearance at the edges.
- Prepare the cucumber cups while the fish marinates: trim the cucumber slices with a round cutter to remove the rind. Using a melon baller or small spoon, scoop a shallow pocket in the center of each slice, taking care not to cut through the bottom.
- Just before serving, fill each cucumber cup with a portion of the ceviche mixture.
- Garnish each cup with a small dot of sour cream or avocado if desired, and top with a cilantro leaf for color.
Notes
This recipe was adapted from a culinary school demonstration. Ceviche is best eaten fresh—do not let it sit for many hours because the texture will continue to firm in the citrus. If you prefer a milder acid flavor, use half the lime and finish with a squeeze just before serving.

I visited a professional culinary campus where students prepared and served a variety of dishes; watching skilled cooks work through the techniques reminded me how much technique and timing matter with delicate preparations like ceviche. If you enjoy exploring food and technique, try making a few variations at home—different fish or shellfish, extra fresh herbs, or a colorful mix of peppers will keep the basic method fresh and versatile.
