How to Make Cauliflower Jalapeño Popper Casserole
Step 1: Preheat the Oven
Preheat your oven to 375F. Line two baking sheets with parchment paper to prevent sticking.
Step 2: Prepare Chicken and Jalapeños
Place the chicken breasts and halved jalapeños on one baking sheet. Drizzle them with olive oil and season lightly with salt. On the second sheet, arrange the bacon strips. Bake both sheets for 20–25 minutes until the chicken reaches an internal temperature of 165F and the bacon is crisp.
Step 3: Mix Cheese Mixture
In a large mixing bowl, combine ¾ cup of shredded cheddar cheese, cream cheese, light sour cream, low-fat milk, smoked paprika, and optional cayenne pepper. Stir until smooth to create a creamy mixture.
Step 4: Shred Chicken and Prepare Other Ingredients
Once cooled slightly, shred the baked chicken using two forks. Crumble the bacon into small pieces and dice the roasted jalapeños.
Step 5: Combine Ingredients
Add the shredded chicken, ¾ of the chopped jalapeños, and ¾ of the crumbled bacon to your cheese mixture. Stir everything together until well-combined.
Step 6: Assemble Casserole
Spread the fresh cauliflower florets evenly across the bottom of a greased 9×12-inch baking dish. Top them with your chicken-cheese mixture and spread evenly across. Finally, sprinkle the remaining cheddar cheese, jalapeños, and bacon over the top.
Step 7: Bake Until Golden Brown
Bake your casserole in preheated oven for about 20 minutes or until it is hot throughout and golden brown on top.
