This recipe uses straightforward ingredients that work beautifully together, creating layers of flavor, texture, and color. Each one plays a crucial role, from the creamy Velveeta that melts perfectly, to the bright green bell pepper adding freshness and crunch. Here’s what you need to gather before diving in:
- 8 oz. small elbow macaroni: The perfect pasta shape to hold on to that cheesy, spicy sauce in every bite.

- 1 (10 oz.) can diced tomatoes with green chilies (hot or mild), undrained: Infuses the dish with flavorful spice and juiciness.
- 8 oz. Velveeta cheese, cubed: Melts into a velvety, creamy cheese sauce that’s the heart of this recipe.
- 1 teaspoon chili powder: Boosts the Tex-Mex vibe with warm, smoky spices.
- 1 teaspoon ground cumin: Adds an earthy, aromatic note that deepens the flavor profile.
- 10.5 oz. cream of mushroom soup: Brings a savory, smooth thickness to the casserole.
- ½ cup sour cream: Adds a tangy creaminess that balances spice and complements the cheese.
- 3-4 cups cooked chicken, cubed (rotisserie works well): Tender protein that makes this dish hearty and satisfying.
- 1 cup crushed tortilla chips: Provides a delightful crunchy texture topping.
- 2 cups shredded sharp cheddar cheese, divided into 2 (1-cup) portions: Melts beautifully and adds a sharp, zesty finish both inside and on top.

How to Make King Ranch Chicken Mac and Cheese Recipe
Step 1: Cook the Macaroni
Start by boiling your elbow macaroni in a large pot of salted water until it’s just al dente—meaning it’s tender but still has a bit of a bite. This will ensure that the pasta doesn’t get mushy after baking. Drain it well and set aside, but keep it warm if you can, so it’s ready to absorb that rich sauce.
Step 2: Sauté the Vegetables
In a large skillet, melt the unsalted butter together with olive oil over medium heat. Add the diced sweet yellow onion and green bell pepper, cooking until they soften and become fragrant—about 5 minutes. These veggies are the flavor base, so be patient and let them get slightly caramelized for maximum sweetness and depth.
Step 3: Build the Sauce
Add the can of diced tomatoes with green chilies (undrained) to the skillet, stirring to combine. Sprinkle in the chili powder and ground cumin to infuse that southwestern character. Next, stir in the cubed Velveeta cheese so it begins melting into the veggies and tomatoes. The cream of mushroom soup comes next, adding a luxurious smoothness, followed by the sour cream, which balances the heat with tangy richness. Stir continuously until everything is well combined and creamy.
Step 4: Combine Chicken and Pasta
Toss your cooked chicken cubes and drained macaroni into the skillet with the sauce. Gently fold everything together so each pasta noodle is coated in the cheesy, spicy mixture and the chicken is evenly distributed. This part is where the magic happens as all elements unify into the ultimate comfort meal.
Step 5: Layer and Bake
Preheat your oven to 350°F (175°C). Transfer half of the macaroni and chicken mixture into a buttered casserole dish. Sprinkle with one cup of shredded cheddar cheese, then add the rest of your pasta mixture. Top with the remaining cup of shredded cheddar cheese and crushed tortilla chips to create a golden, crispy crust as it bakes. Bake uncovered for about 25 minutes until bubbly and the cheese topping melts into a glorious, slightly crispy finish.

Make Ahead and Storage
Storing Leftovers
After enjoying your delicious casserole, store any leftovers in an airtight container placed in the refrigerator. They’ll stay fresh for up to 4 days. Before covering, allow the dish to cool slightly but not completely, to avoid condensation making the topping soggy.
Freezing
If you want to prepare this King Ranch Chicken Mac and Cheese Recipe in advance, it freezes beautifully. Assemble in a freezer-safe dish but don’t bake it yet. Wrap tightly with foil and freeze for up to 3 months. When ready, thaw overnight in the fridge and bake as directed.
Reheating
Reheat individual portions in the microwave until warmed through, or reheat the entire casserole in a 350°F oven until bubbly and crisp on top again. If microwaving, add a splash of milk or cream on top to maintain creaminess and prevent drying out.
FAQs
Can I use different types of pasta for this recipe?
Absolutely! While elbow macaroni is traditional, you can experiment with small shells, rotini, or penne to change up the texture, as long as they are bite-sized to hold the sauce well.
Is rotisserie chicken the best option for this dish?
Rotisserie chicken is convenient and flavorful, making it a popular choice, but you can also use leftover roasted chicken, grilled chicken breasts, or even shredded turkey if you prefer.
Can I make this recipe milder or spicier?
Definitely adjust the heat to your taste. Use mild diced tomatoes with green chilies for a gentler flavor or choose hot for extra kick. You can also increase or reduce the chili powder and cumin accordingly.
What can I substitute for Velveeta cheese?
If you can’t find Velveeta, use a combination of processed cheese slices or a smooth melting cheese like Monterey Jack, but the sauce won’t be quite as creamy and smooth.
Is this recipe suitable for meal prep?
Yes! King Ranch Chicken Mac and Cheese Recipe reheats well, making it an excellent choice for meal prep. Just portion it out into airtight containers for quick, ready-to-eat lunches or dinners throughout the week.

- Ensure the crushed tortilla chips are used as a topping for nice texture contrast, not stirred inside.
