Ingredients

Jalapeño peppers (8 large): Fresh, crisp jalapeños halved and seeded unless you prefer more heat with seeds included.
Lump crabmeat (7 ounces): Sweet and tender crab pieces carefully picked over for shells to ensure a smooth filling.
Cream cheese (3.5 ounces, softened): Adds a rich, creamy texture that binds the filling and balances the spice.
Shredded cheddar cheese (0.5 cup): Provides sharpness and melts perfectly into the crab mixture for extra flavor.
Mayonnaise (2 tablespoons): Helps create a moist, smooth filling that holds all ingredients together.
Green onions (2, finely chopped): Adds a fresh, mild onion flavor and crunch to the filling.
Garlic (1 clove, minced): Delivers a subtle pungency to complement the seafood blend.
Fresh parsley (2 tablespoons, chopped): Brightens the flavor profile with a fresh herbaceous note.
Lemon zest (1 teaspoon): Infuses a citrusy brightness that balances the richness of the cheese and crab.
Cajun seasoning (1 teaspoon): A signature blend of spices that brings authentic southern heat and flavor.
Smoked paprika (0.25 teaspoon): Adds a smoky depth, enhancing the overall savory taste.
Salt (0.25 teaspoon): Enhances all the flavors without overpowering.
Black pepper (0.25 teaspoon): Gives a gentle sharpness for balanced seasoning.
Panko breadcrumbs (0.25 cup): Light, airy breadcrumbs mixed with butter create a crunchy golden topping.
Unsalted butter (1 tablespoon, melted): Coats the breadcrumbs to help achieve an irresistible crispy crust.

Instructions

Preheat the oven and prepare jalapeños: Set your oven to 400°F and line a baking sheet with parchment paper for easy cleanup. Halve the jalapeños lengthwise and carefully remove seeds and membranes using a small spoon; gloves are recommended to prevent irritation. This step controls the spice level and ensures even cooking.
Mix the creamy crab filling: In a mixing bowl, combine softened cream cheese, mayonnaise, shredded cheddar cheese, finely chopped green onions, minced garlic, chopped fresh parsley, lemon zest, Cajun seasoning, smoked paprika, salt, and black pepper. Stir thoroughly until a smooth, flavorful mixture forms—this creates the base that complements the crab perfectly.
Fold in the crabmeat gently: Carefully fold the lump crabmeat into the cheese mixture, being gentle to keep the large chunks intact. This preserves the texture and ensures that each popper bursts with crab flavor rather than being mushy.
Stuff the jalapeños with filling: Spoon the crab filling evenly into each jalapeño half, mounding it slightly over the edge. This generous filling ensures each bite has a balance of pepper and savory crab goodness.
Prepare breadcrumb topping and add: Mix the panko breadcrumbs with melted butter until the texture resembles wet sand. This buttery mixture will crisp up beautifully, providing a golden, crunchy topping when baked.
Bake until golden and bubbly: Arrange the filled poppers on the lined baking sheet, ensuring they sit evenly. Bake for 18 to 20 minutes or until the breadcrumbs turn golden brown and the filling is heated through. This process melds together the flavors and textures perfectly.
Cool and serve: Remove the poppers from the oven and allow them to cool for 5 minutes before serving. This makes them safer to handle and allows the flavors to settle for optimal taste.

You Must Know

Storage Tips

Store any leftover poppers in an airtight container in the refrigerator for up to 3 days. Reheat them in the oven to maintain the crispy breadcrumb topping and warm the filling evenly.
