King Ranch Chicken Macaroni and Cheese Recipe
Growing up, King Ranch Chicken was one of the recipes I would ask Mom to make time and time again. I just love the creaminess, the creative flavor combo, and that little touch of spiciness. So, I loaded up this casserole with all the traditional ingredients Mom used and combined them with the creaminess of mac and cheese. What a flavor bomb! Traditional King Ranch Chicken recipes have bits of tortillas baked in, so I added a layer of crushed tortilla chips on top, so I could stay true to the recipe.
Haters of King Ranch Chicken like to complain that it has Velveeta (check) and cream of mushroom soup (check check), but sometimes that’s okay. I find that both of these ingredients add loads of flavor and texture.
Tips for Beginners
- Don’t overcook the pasta. The pasta will continue to bake as the casserole bakes, so make sure it is cooked al dente, or you’ll end up with mushy pasta.
- Any pasta shape works. I love using elbow macaroni, but any short-shaped pasta will work.
- Don’t compromise on the resting time. This allows the casserole to firm up so you can easily cut and serve it.

How to Make King Ranch Chicken Mac and Cheese Step by Step

Get the oven going and prepare the pasta: Preheat the oven to 350°F. Spray a 2-quart baking dish with cooking spray. Cook one 8 oz. package of macaroni as per package directions to al dente and drain.

Cook the veggies: Heat 2 tbsp butter and 2 tbsp oil in a large Dutch oven over medium-high heat. Sauté diced onion and diced bell pepper until the pepper is tender and the onion is translucent.

Add tomato, cheese, and spices: Stir one undrained can of diced tomatoes with green chilies, 8 oz. Velveeta, 1 tsp chili powder, and 1 tsp cumin. Cook, stirring for 1-2 minutes over medium-low heat until the cheese melts.

How to Store
Store leftovers in an airtight container in the fridge for 3-4 days. Reheat in the microwave or oven. You could freeze leftovers, but I find pasta that’s been frozen and thawed has a different texture that I don’t love. If you do want to freeze it, wrap it tightly and freeze it for up to 3 months. Thaw in the fridge overnight before reheating.
Serving Suggestions
This King Ranch mac and cheese is one hearty casserole, so I like to go a little lighter on the sides. I’ll prepare sauteed mushrooms, or to add something green, these garlic parmesan Brussels sprouts are always a favorite option. To start the meal off, I usually prepare a simple green goddess salad.

I commented on this before and just made it again because we liked it so much, but I just want to say that I don’t see how in the world this would all fit into a 2 quart casserole. The first time I used a 2.5 quart one, which was tight, and tonight a 3.5 quart. It fit, but there wasn’t all that much space left, certainly not 1.5 quarts’ worth!
Great suggestion! Thank you, Helen!!
I came across this recipe by chance and made it the other night, and must say it was one of the best versions of mac and cheese we’ve ever had! I’ll be making it again and trying some of your other recipes as well.
That makes me so happy to hear! Thanks, Helen!
This sounds like the ultimate comfort food! I’m all about using Velveeta and canned mushroom soup! I’m sure homemade is great, but the canned is just so easy. And Velveeta, YUM. It may not be “real” cheese, but it’s pretty tasty in my book :-)
