How to Make King Ranch Mac and Cheese Recipe
Step 1: Cook the Pasta
Start by bringing a large pot of salted water to a boil and cook the elbow macaroni just until al dente, following the package instructions. This ensures your pasta will hold its shape through baking without turning mushy. Drain the pasta well and set aside so it’s ready to be combined with that flavorful sauce.
Step 2: Sauté the Vegetables
In a large skillet, melt the butter over medium heat and add the finely chopped yellow onion along with the diced red and green bell peppers. Cook these together until they soften and release their natural sweetness, about 5 minutes. This step is essential for creating a savory foundation that adds both texture and complexity to the final dish.
Step 3: Add Tomatoes and Chicken
Stir in the drained diced tomatoes with green chiles and the cooked shredded chicken into the softened vegetables. Let this mixture cook for 2 to 3 minutes to combine flavors and warm through. Using cooked chicken here makes weeknight dinners so much easier without compromising flavor or heartiness.
Step 4: Make the Cheese Sauce
Sprinkle the flour evenly over the chicken and vegetable mixture, stirring well to ensure it coats everything. Gradually pour in the whole milk and heavy cream, stirring constantly until the sauce begins to thicken, which will take about 4 to 5 minutes. This creamy, thickened base is what turns the dish into that irresistible, saucy mac and cheese magic.
Step 5: Spice Things Up
Season your sauce by adding chili powder, ground cumin, garlic powder, salt, and black pepper. Stir everything together on low heat until aromatic and well combined. These warm spices add the signature Tex-Mex flair to this classic comfort food.
Step 6: Melt in the Cheese and Sour Cream
Lower the heat and stir in the shredded sharp cheddar and Monterey Jack cheeses until they melt smoothly into the sauce. Remove the pan from the heat and fold in the sour cream for a luscious creaminess and a hint of tang that will make your taste buds dance.
Step 7: Combine and Bake
Fold the pre-cooked elbow macaroni into the cheesy chicken mixture until every piece is wonderfully coated. Transfer the entire mixture evenly into a greased 9×13-inch baking dish. Bake at 375°F for 20 to 25 minutes until bubbling hot and golden on top. Let it rest for a few minutes before serving to allow the flavors to settle perfectly.

Make Ahead and Storage
Storing Leftovers
