How To Make These Blueberry Crostini Appetizers With Ricotta and Jalapeños
Ingredients You’ll Need For This Recipe
- 1 French baguette
- 1 cup fresh blueberries
- ½ red onion
- 1 tablespoon lemon juice
- 1 teaspoon balsamic vinegar
- ½ teaspoon sugar
- Salt and pepper
- 1 cup ricotta cheese
- 1–2 whole pickled jalapeños
Step-by-Step Guide
1. Finely chop the red onion and jalapeños.
2. In a small saucepan, combine the blueberries, chopped red onion, balsamic vinegar, sugar, lemon juice, salt, and pepper on medium-high heat.
3. Let the mix simmer gently for about 4–5 minutes, just until the blueberries soften and the sauce thickens slightly. Set aside to cool.
4. Slice your baguette into thin pieces (around an inch thick), cutting slightly diagonally for a more elegant look.
5. Lay the baguette slices on a baking tray and brush them lightly with olive oil.
6. Toast under the grill for about 5-7 minutes until the edges start to turn golden brown and crispy.
7. If your blueberry mixture has released too much liquid, strain off the excess so you’re left with the flavorful, chunky topping.
8. Spread each toasted slice with a generous teaspoon of ricotta.
9. Add about one teaspoon of the blueberry-onion mix on each base.
10. Garnish with a few thin slices or pieces of pickled jalapeños for a zingy bite.
11. Serve immediately.
