King Ranch Chicken Macaroni and Cheese Casserole
This King Ranch Chicken Macaroni and Cheese Casserole combines two family favorites into one cheesy, comforting dinner! Tender chicken and elbow macaroni are tossed in a creamy, slightly zesty cheese sauce with peppers, tomatoes, and warm spices. Everything gets topped with shredded cheddar cheese and baked until hot and bubbly. It’s a delicious twist on classic King Ranch Chicken Casserole that the whole family will enjoy!

This casserole has a mild kick from the diced tomatoes with green chiles and chili powder, but it isn’t overly spicy. For a milder version, use mild diced tomatoes with green chiles. To add extra heat, try adding diced jalapeños or a pinch of cayenne pepper.
Yes! Assemble the casserole as directed, but don’t bake it yet. Cover tightly and refrigerate for up to 24 hours. When ready to cook, bake at 350°F until the cheese is melted and the casserole is heated through. You may need to add 5-10 minutes to the baking time if it’s going straight from the refrigerator to the oven. Make sure the center reaches 165°F.
Absolutely! Small pasta shapes like shells, rotini, or penne work well in this recipe. Just be sure to cook the pasta al dente before mixing it into the cheese sauce
