How to Make King Ranch Chicken Mac and Cheese Recipe
Step 1: Cook the Pasta
Start by boiling the elbow macaroni according to the package directions until it’s perfectly al dente. This ensures your noodles will stand up to the creamy sauce without getting mushy in the oven. Once done, drain them well and set aside—they’ll be ready for their cheesy transformation soon!
Step 2: Sauté the Veggies
Melt the butter in a large skillet or saucepan over medium heat. Toss in your diced onion and both bell peppers, and sauté for about 4 to 5 minutes, stirring occasionally. You’re looking for the veggies to soften and get beautifully fragrant. Add the minced garlic and cook for another 30 seconds, just until aromatic—don’t let it burn!
Step 3: Make the Sauce
Sprinkle the flour over the sautéed veggies and stir for a minute to create a quick roux. This step is key for thickening the sauce without lumps. Slowly whisk in the chicken broth and milk, making sure everything gets combined smoothly. Add the chili powder, cumin, salt, and black pepper, and let the mixture simmer for 3 to 4 minutes until it thickens up just a bit.
Step 4: Bring in the Tex-Mex Magic
Reduce the heat to low, then stir in the shredded chicken, drained diced tomatoes with green chilies, and sour cream. The combination instantly brings those classic King Ranch flavors to life. Fold in the cooked pasta, giving everything a gentle stir so the noodles are evenly coated in that creamy, spiced sauce.
Step 5: Add the Cheese and Bake
Mix in 1 1/2 cups of the cheddar cheese and 1/2 cup of the Monterey Jack cheese, stirring until they melt into the sauce. Pour the entire mixture into a greased 9×13-inch baking dish and spread it out evenly. Scatter the remaining cheese over the top for that irresistible golden crust. Bake at 375°F (190°C) for 15 to 20 minutes, or until the casserole is bubbling and beautifully golden on top.
Step 6: Garnish and Serve
Once out of the oven, let your King Ranch Chicken Mac and Cheese Recipe cool for a few minutes. Sprinkle with chopped fresh cilantro if you like, then dig in while it’s still hot and melty. Pure comfort in every bite!
How to Serve King Ranch Chicken Mac and Cheese Recipe

Garnishes
For an extra pop of color and flavor, I love to top my King Ranch Chicken Mac and Cheese Recipe with a generous sprinkle of fresh cilantro. If you’re feeling fancy, a few slices of fresh jalapeño or a handful of crushed tortilla chips add crunch and visual flair. Even a dollop of extra sour cream can make each serving feel special.
Side Dishes
This casserole is a meal in itself, but it pairs beautifully with a crisp green salad dressed in lime vinaigrette or a bowl of simple black beans. Warm, buttered cornbread is always a welcome side, or you can serve it with roasted veggies to keep things light and balanced.
Creative Ways to Present
Try serving individual portions in small cast iron skillets for a rustic, restaurant-style feel, or spoon it into taco shells for a Tex-Mex mac and cheese taco night! For parties, bake the casserole in muffin tins for easy, hand-held servings—perfect for game day or potlucks.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftovers (lucky you!), simply cover the casserole dish tightly or transfer portions to an airtight container. Your King Ranch Chicken Mac and Cheese Recipe will keep well in the refrigerator for up to 3 days, and the flavors deepen overnight.
Freezing
This recipe freezes surprisingly well. Cool the casserole completely before wrapping tightly in foil or placing in a freezer-safe container. Freeze for up to 2 months. When ready to enjoy, thaw in the refrigerator overnight for best results.
Reheating
To reheat, cover with foil and bake at 350°F until heated through (about 20 minutes), or microwave individual servings for 2 to 3 minutes. Add a splash of milk if needed to restore creaminess, and top with fresh cilantro or cheese before serving to revive that just-baked taste.
FAQs
Can I use a different kind of pasta?
Absolutely! While elbow macaroni is classic for this King Ranch Chicken Mac and Cheese Recipe, shells, rotini, or penne all work beautifully—just aim for small pasta shapes that hold sauce well.
Is there a way to make this dish spicier?
If you like a little extra heat, add more chili powder or toss in some diced jalapeños with the bell peppers. You can also use pepper jack cheese in place of Monterey Jack for a gentle spicy kick.
Can I prepare this casserole ahead of time?
Definitely! Assemble the casserole up to the point of baking, cover tightly, and refrigerate for up to 24 hours. When you’re ready to eat, just bake as directed—add a few extra minutes to the baking time if it’s coming straight from the fridge.
What’s the best way to shred chicken for this recipe?
Rotisserie chicken is a lifesaver here—just shred it with two forks or your hands. If you’re cooking chicken from scratch, poach or bake boneless, skinless breasts or thighs until cooked through, then shred while warm for easiest results.
Can I make this King Ranch Chicken Mac and Cheese Recipe gluten-free?
Yes! Just swap in your favorite gluten-free pasta and use a gluten-free flour blend when thickening the sauce. Double-check that your chicken broth and other ingredients are gluten-free, too.
