Step‑by‑Step Instructions for Jalapeno Popper Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it heats up, grease a 12 x 9-inch casserole dish with non-stick spray or a light coating of oil to ensure easy removal of the delicious Jalapeno Popper Chicken Casserole later.
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil and cook the rotini pasta according to the package instructions until al dente, usually about 8-10 minutes. Once cooked, drain the pasta well and set it aside in a mixing bowl while you prepare the other ingredients.
Step 3: Cook the Chicken and Bacon
In a large skillet over medium heat, add bite-sized pieces of boneless skinless chicken and crumbled bacon. Cook for about 7-10 minutes until the chicken is fully cooked through and the bacon is crispy. Drain any excess fat and keep the flavors sizzling in the skillet.
Step 4: Prepare the Vegetables
While the chicken and bacon are cooking, dice the jalapeno peppers, removing the seeds for less heat, and slice the green onions thinly. Set these aside as they will bring fresh flavors to the Jalapeno Popper Chicken Casserole.
Step 5: Mix the Creamy Base
In a mixing bowl, combine the softened cream cheese, sour cream, milk, 1½ cups of shredded Mexican cheddar jack cheese, diced jalapenos, and most of the sliced green onions. Blend these ingredients until smooth, creating a creamy, flavorful mixture to fold into your casserole.
Step 6: Combine the Pasta, Chicken, and Bacon
In your greased casserole dish, add the drained rotini pasta from earlier, followed by the cooked chicken and bacon. Use a spatula to gently mix them together, ensuring everything is evenly distributed before adding the creamy base for the Jalapeno Popper Chicken Casserole.
Step 7: Incorporate the Creamy Mixture
Spoon the prepared cream cheese mixture evenly over the pasta, chicken, and bacon combination in the casserole dish. Gently fold and mix everything together until all ingredients are well coated in that luscious creamy goodness.
Step 8: Add the Toppings
Sprinkle the remaining shredded cheese, bacon, and any leftover jalapeno or green onion slices on top of the casserole mixture. This extra layer will create a deliciously cheesy and crunchy topping when baked.
Step 9: Bake to Perfection
Place the assembled Jalapeno Popper Chicken Casserole in your preheated oven and bake for 20 minutes. Look for the edges to bubble and a golden crust on top to ensure it’s nicely cooked and ready to serve.
