I always start by setting the oven to 375°F (190°C). This temperature melts the brie gently while crisping the prosciutto perfectly. If using an air fryer, line the basket with parchment for easy cleanup.
Slice each jalapeño lengthwise and remove seeds and membranes. Pat them dry with a paper towel so the brie sticks better. I sometimes rinse them with cold water for milder heat.
Cut brie into small chunks and place inside each jalapeño half. Don’t overfill—the cheese expands as it melts. I personally love using triple-cream brie for an indulgent touch.
Wrap each filled jalapeño with a slice of prosciutto, ham, or bacon. If using bacon, I lightly pre-cook it for 2–3 minutes so it crisps evenly. Arrange them on a parchment-lined baking sheet.
Bake for 15–20 minutes or until the meat is crisp and brie starts bubbling. In an air fryer, they finish in 12–15 minutes. I rotate halfway through to cook them evenly.
Warm 1/3 cup of blueberry preserves and drizzle over the hot poppers. I sometimes add a splash of balsamic vinegar to balance the sweetness.
Top with black pepper or flaky salt for a finishing touch. Serve immediately to enjoy the creamy brie, crisp meat, and sweet blueberry combination.
