some tips for preparing for making this recipe

  1. Be sure to use thick cut bacon – thick cut is important so it doesn’t overcook or become too crispy when air frying or baking.
  2. Use a block of cheddar cheese vs pre-shredded because they have additives like starch to prevent clumping.

*Be sure to check out the full recipe and ingredient list below.

  • Cook bacon until desired crispiness and allow to cool. Once cooled, chop the bacon slices into pieces. Cut jalapeños in half lengthwise and remove the membranes, stem/seeds. 
  • Tip: wear gloves! It helps to prevent the heat from the jalapeños getting to places they don’t belong. Have you ever rubbed your eyes after cutting up hot peppers? And you thought you washed your wands well enough. Um, yeah not pleasant!
  • Layer the jalapeños like this: cream cheese, bacon crumbles, shredded cheddar cheese.
  • Use a teaspoon to spoon the cream cheese over the jalapeno pepper halves. Then add the pre-cooked bacon pieces over the cream cheese mixture.
  • Sprinkle the shredded cheddar cheese over the cream cheese filling.
  • Place the prepared jalapeno halves in the basket of the Foodi or Air Fryer.
  • Set the air fryer to 390 degrees, F. Or if using the Ninja Foodi set to the air crisp function. They will cook for about 8 minutes.

Oven directions: Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper. Fill each jalapeño pepper half with cream cheese, chopped bacon pieces, shredded cheddar cheese, as usual. Place on the prepared baking sheet. Bake in the preheated oven until jalapeños are tender and cheese melts, about 20 minutes.

If you have leftover poppers, store in an airtight container in the fridge for about 3 days. Reheat in the air fryer at 390 degrees, F until warmed through.

FAQ (frequently asked questions)

Are jalapeno poppers keto friendly?

Jalapeños are generally low in carbs at only 1 carb in an average jalapeño pepper. They make a great addition to a low carb/keto diet and a staple in my opinion. If enjoying poppers on a keto diet, be sure to watch portion sizes because of the carbs in dairy.

Can these poppers be made in the oven instead of an air fryer?

Yes, I’ve updated this recipe to include oven instructions. They do take 20 minutes to bake up in the oven vs a quick 8-10 minute time in the air fryer. See complete instructions in the printable recipe card.

To make in an air fryer / Ninja Foodi

  • Add the poppers to the air crisp basket of the Ninja Foodi or Air Fryer on a single layer. Set the function to air crisp, 390° F. And cook for about 8 minutes.
  • Allow to cool for a couple of minutes before removing from the Ninja Foodi.
  • Serve and enjoy!

To make in the oven

  •  Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper.
  • Fill each jalapeño pepper half with cream cheese, chopped bacon pieces, shredded cheddar cheese, as usual.

You may need to press the bacon into the cream cheese a bit to prevent it from falling off.
