Condensed Cream of Chicken Soup
Adds richness, thickness, and a savory base that binds everything together.
Condensed Cream of Mushroom Soup
Brings earthiness and depth to balance spices and tomatoes.
Chicken Broth
Thins the sauce slightly and adds flavor to prevent the casserole from drying out.
Diced Tomatoes with Green Chilies
Signature King Ranch addition providing tang, moisture, and mild heat.
Cheddar Cheese
Melts smoothly and supplies classic mac-and-cheese flavor; sharp varieties boost intensity.
Sour Cream
Adds creaminess and mild tang to enrich the sauce.
Chili Powder, Garlic Powder, and Onion Powder
Tex-Mex spices that create warmth and savoriness without overpowering heat.
Butter
Helps achieve a golden, bubbly finish on top.
Tips & Tricks
Cook Macaroni Al Dente
Cook the macaroni al dente so it doesn’t overcook in the oven.
Mix in Extra Cheese
For a richer flavor, mix in half a cup of Monterey Jack cheese or pepper jack cheese.
Add Broth if Needed
If your sauce looks too thick before baking, add a splash of broth to loosen it.
Pro Tips
- Do not skip draining the tomatoes, as extra liquid prevents the casserole from setting properly.
- Let the casserole rest for a few minutes before serving so it becomes easier to scoop.
- For a spicy version, add diced jalapeños, a pinch of cayenne, or hot green chilies.
Step-by-Step Instructions
Preheat the Oven
Preheat your oven to 350°F (175°C) to ensure even cooking and a golden, bubbly top.
Cook the Macaroni
Cook the macaroni according to package directions, ensuring it is al dente. This helps maintain the pasta's texture after baking. Drain and set aside.
Prepare the Sauce
In a large bowl, stir together the condensed cream of chicken soup, cream of mushroom soup, chicken broth, diced tomatoes with chilies, sour cream, chili powder, garlic powder, onion powder, salt, and pepper. This blend creates the flavorful base of the casserole.
Combine Ingredients
Add the cooked macaroni and shredded chicken to the sauce mixture. Stir to ensure everything is evenly coated and well combined.
Add Cheese
Stir in 1 cup of cheddar cheese until it is evenly incorporated into the mixture, adding creaminess and depth of flavor.
Transfer to Baking Dish
Transfer the mixture to a greased baking dish, spreading it evenly for consistent cooking.
Top with Cheese and Butter
Sprinkle the remaining cheddar cheese over the top and dot with butter to enhance the golden finish.
Bake the Casserole
Bake in the preheated oven for 25–30 minutes until the casserole is hot, bubbly, and lightly browned on top.
Rest Before Serving
Let the casserole cool for 5 minutes before serving. This resting period allows the flavors to meld and makes it easier to serve.
Delicious Variations
Protein Swap
Replace the chicken with cooked turkey, perfect for using up post-holiday leftovers and adding a different flavor profile.
Cheese Blend
Use a mix of cheddar, Monterey Jack, and Colby cheeses for a creamier, more dynamic melt.
Vegetable Boost
Add vegetables like bell peppers or onions to introduce extra crunch and nutrients to your casserole.
