This Keto Jalapeno Popper Chicken Casserole is a celebratory low-carb dish featuring creamy cheese, spicy jalapenos, and tender chicken. Jalapenos are the star ingredient in the casserole dish, making each bite exciting and flavorful. You can adjust the level of spiciness to be fiery or mild enough to excite your palate. The cheese rounds out the spiciness well and adds a gooey texture that contrasts the crunchy toppings beautifully.
The recipe frequents our dinner table because we love Tex-Mex flavors, and it's ready in a flash. It's also easy to make and requires simple pantry basics. Since it reheats beautifully, I recommend cooking a double batch of this spicy chicken casserole so you can have some to enjoy on a lazy weeknight.

How To Cook Keto Jalapeno Popper Chicken: Complete Cooking Guide
Cooking Method
- Baking
Preparation Steps
- Gather all the tools and ingredients.
- Preheat the oven to 375°F(190°C).
- Slice the Jalapeno peppers.

- Place the mixture in a casserole dish.
- Layer on the cheddar cheese and top with the reserved jalapeño and bacon bits.
Cooking Instructions

💡 My Pro Tip
A good-sized casserole dish is critical to the success of this recipe. If the dish is too large, the casserole mixture will spread too thin and dry in the oven. If it is too small, the mixture will be deep and potentially not heat through in 20 minutes. I recommend finding a baking dish that will allow for about 1.5 to 2" of uniform thickness for the chicken mixture.
⏲️ Time-Saving Tips
- Use leftover shredded chicken.
- Use pre-shredded cheese to cut prep time.
- Use cooked crispy bacon bits to save more time!
