Create three stations with flour-salt mix, beaten eggs, and panko-paprika-garlic-salt mix.
Fill and bread:
Spoon filling into each pepper half, coat in flour, dip in egg, press into breadcrumbs. Place on plate.
Heat oil:
Heat oil to 350°F in deep skillet (use thermometer).
Fry:
Working in batches of 4-5, fry poppers 2-3 minutes per side until golden brown. Remove with slotted spoon and place on paper towels.
Serve:
Enjoy warm immediately or keep warm in 250°F oven.
Baking Alternative:
Arrange on parchment-lined baking sheet, spray with cooking oil, bake at 400°F for 12-15 minutes, flipping halfway through.
Notes
Make ahead: Prepare and bread poppers the night before, refrigerate covered, cook when ready.
Freezing: Freeze breaded poppers on baking sheet, transfer to freezer bag, store up to 2 months. Fry or bake from frozen, adding 1-2 minutes to cooking time.
Cheese options: Swap cheddar for pepper jack (spicier), Monterey jack, or provolone. Add slice of fresh mozzarella inside for extra creaminess.
Heat level: Remove all seeds and white membrane for milder peppers. Add extra cayenne or use pepper jack for spicier version.
Oil temperature: Critical for success. Too cool = oily, mushy poppers. Too hot = burnt outside, cold inside.
Dipping sauce: Serve with ranch, hot sauce, or make lime crema with sour cream, lime juice, cilantro, and garlic.
Storage: Refrigerate leftovers in airtight container up to 3 days. Reheat in 350°F oven for 5 minutes.
Common issue - Leaking cheese: Make sure filling is cold before breading and coat peppers completely with flour and egg to seal.
Serving size: This recipe makes 24 poppers, perfect for 4-6 people as appetizer or party snack.
