Preheat your oven to 400°F (200°C). This ensures that your jalapeños roast perfectly and the filling gets that desirable golden-brown crust.
While the oven is heating, prepare the jalapeños. Wash and slice each jalapeño in half lengthwise, carefully removing the seeds and membranes with a spoon or knife. This will help reduce their heat, but you can keep some seeds if you prefer a spicier dish.
In a medium mixing bowl, combine the 8 oz softened cream cheese, ½ cup shredded cheddar cheese, ½ cup cooked turkey sausage, 1 clove minced garlic, 1 tsp smoked paprika, 1 tsp onion powder, and salt and pepper to taste. Mix until well incorporated. The filling should be creamy and well-seasoned.
Using a spoon, generously fill each halved jalapeño with the cheese and sausage mixture. Make sure to pack the filling slightly, creating an appealing dome shape.
In a separate bowl, combine 1 cup breadcrumbs with a drizzle of olive oil to help them crisp up in the oven. Sprinkle this breadcrumb mixture evenly over the stuffed jalapeños, ensuring they are well-coated.
Arrange the stuffed jalapeños on a baking sheet, ensuring they are placed cut-side up. This will prevent the filling from spilling out as they cook.
Bake in the preheated oven for 20-25 minutes or until the jalapeños are tender and the breadcrumbs are golden brown. Keep an eye on them to avoid burning.
Once they are done, remove the baking sheet from the oven and let them cool for a couple of minutes. This helps the filling set slightly and makes them easier to handle.
Serve warm, garnished with chopped fresh cilantro or a drizzle of sour cream, if desired.
