Delicious Canapé – Watermelon Radish Bites

Why You’ll Love This Recipe

I like this recipe because it’s simple to make but looks stunning on a platter. The radish slices act as natural crackers, making it gluten-free and lighter than traditional canapés. The tuna with sriracha and mayonnaise adds a creamy, spicy kick, while the microgreens give a fresh finishing touch.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

1 watermelon radish
1 can tuna, drained
2 tablespoons mayonnaise
1 teaspoon sriracha
1 teaspoon kosher salt
pinch of paprika
2 tablespoons microgreens

Directions

1. I start by slicing the watermelon radish thinly into rounds, which serve as the base.
2. In a small bowl, I mix the drained tuna with mayonnaise, sriracha, salt, and paprika until well combined.
3. I spoon a small amount of the tuna mixture onto each radish slice.
4. I top with microgreens for garnish and added freshness.
5. I serve immediately as a crisp, refreshing appetizer.

Servings and Timing

This recipe makes about 12–16 bites, depending on the size of the radish slices. It takes around 10 minutes to prepare, so it’s quick and easy for entertaining.

Variations

Sometimes I swap tuna for canned salmon or crab for a different flavor. If I want less heat, I reduce the sriracha or replace it with Dijon mustard. I also enjoy adding a squeeze of lime juice to brighten the tuna mixture or topping with sesame seeds for extra crunch.

Storage/Reheating

I prefer serving these fresh, as the radish can release water and soften the topping over time. If I want to prep ahead, I keep the tuna mixture refrigerated in a sealed container for up to 2 days and assemble the canapés right before serving.

FAQs

Can I make these ahead of time?

I prepare the tuna mixture ahead but assemble just before serving to keep the radishes crisp.

Can I use regular radishes instead of watermelon radish?

Yes, but watermelon radishes are larger and have a beautiful color that makes the bites more striking.

How do I slice the radish thinly?

I use a mandoline for even, thin slices, but a sharp knife works too.

Can I make this recipe spicier?

Yes, I add extra sriracha or a pinch of cayenne pepper.

Can I make it milder?

Yes, I reduce or omit the sriracha and just use mayonnaise for creaminess.

What microgreens work best?

I like using arugula, pea shoots, or radish microgreens for flavor and presentation.

Can I make this dairy-free?

Yes, I use dairy-free mayonnaise.

What protein alternatives can I use?

I sometimes use cooked shredded chicken or smoked salmon instead of tuna.

Can I add extra toppings?

Yes, avocado slices, sesame seeds, or pickled onions make great additions.

What drink pairs well with this appetizer?

I like serving it with a crisp white wine or sparkling water with citrus.

Conclusion

Watermelon radish bites are a light, refreshing, and eye-catching canapé that I love making for parties and gatherings. With their crisp base, creamy tuna topping, and fresh garnish, they’re always a crowd-pleaser and a perfect way to serve a healthy yet flavorful appetizer.
