You can make these jalapeno poppers ahead of time and reheat them again when needed. Or you can make them fresh when you feel like it. Either way, they turn out super crispy & delicious. Once cooked, let them come to room temperature. Then store the jalapeno poppers in freezer-safe containers or bags. You can keep them in the freezer for 2-3 months. Then, when you want to eat them again, just reheat them in the air fryer or in the oven for few minutes, and enjoy!
