Prep the peppers: Slice jalapenos lengthwise and remove seeds and membranes.
For less heat, scrape thoroughly; for more kick, leave a little membrane.
Preheat the air fryer: Set to 375°F (190°C) for 3–5 minutes so the basket is hot when the peppers go in.
Make the filling: In a bowl, mix cream cheese, cheddar, Monterey Jack, bacon, green onions, garlic, onion powder, paprika, a pinch of salt, and black pepper. Stir until smooth and evenly combined.
Fill the peppers: Spoon or pipe the cheese mixture into each jalapeno half, mounding slightly but not overflowing.
Prepare the basket: Lightly spray the air fryer basket with oil or place a perforated parchment liner inside. This helps prevent sticking and keeps the bottoms crisp.
Air fry in batches: Arrange stuffed peppers in a single layer, not touching.
Air fry for 7–9 minutes at 375°F, until the peppers are tender and the tops are golden and bubbly.
Check doneness: The cheese should be melted and lightly browned. If needed, cook 1–2 minutes more. Avoid overcooking or the peppers may collapse.
Finish and serve: Let cool 2–3 minutes, then garnish with cilantro or extra green onions.
Add a small drizzle of hot honey if you like sweet heat.
