Step‑by‑Step Instructions for Easy King Ranch Chicken Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C) and greasing a 9×13-inch baking dish with a little butter or cooking spray. This sets the stage for your Easy King Ranch Chicken Casserole, ensuring it bakes evenly while preventing sticking. Gather all of your ingredients so they are within arm’s reach for quicker assembly.
Step 2: Sauté the Vegetables
In a large skillet, melt 2 tablespoons of unsalted butter over medium-high heat. Once melted, add the chopped red bell pepper, yellow onion, and optional jalapeño. Sauté the mixture for about 6 minutes until the vegetables are tender and fragrant, brightening your kitchen with savory aromas. Stir occasionally to ensure even cooking.
Step 3: Season the Mixture
Next, stir in 1 tablespoon of chili powder and 2 teaspoons of ground cumin, cooking for an additional minute until the spices become fragrant. This step infuses the sautéed veggies with warmth and depth, which will elevate your Easy King Ranch Chicken Casserole. Once fragrant, remove the skillet from heat to prevent burning the spices.
Step 4: Mix the Filling
In a mixing bowl, combine the softened 8 ounces of cream cheese with the sautéed vegetable mixture until it’s well blended and creamy. Then, add 2 cans of drained diced tomatoes with green chiles, shredded rotisserie chicken, 1.5 cups of sour cream, and 1 teaspoon of kosher salt. Mix it all together until it forms a smooth filling, creating the delightful heart of your casserole.
Step 5: Assemble the Casserole
Begin layering your Easy King Ranch Chicken Casserole. Start with a generous layer of the chicken mixture in the greased baking dish, followed by a sprinkle of 1 cup of shredded Monterey Jack cheese and half of the warmed corn tortillas, cut into quarters. Repeat the layering process, finishing with the remaining chicken mixture and topping off with the last cup of cheese for that delicious, melty finish.
Step 6: Bake to Perfection
Place the assembled casserole into the preheated oven and bake for 15-20 minutes, or until the cheese is wonderfully melted and the edges are bubbling. For an extra golden and crispy top, broil the casserole for an additional 1-2 minutes. Keep a close eye on it to prevent burning, and get ready for the delightful aroma to fill your home.
Step 7: Rest and Garnish
Once baked to perfection, remove the Easy King Ranch Chicken Casserole from the oven and let it rest for about 10 minutes. This step allows the flavors to meld and makes serving easier. If desired, garnish with freshly chopped cilantro for a pop of color and flavor before diving in.
