Cheesy, beefy, and a little spicy, this one-pot chili mac recipe is a Tex-Mex spin on classic macaroni and cheese! It's ready in 30 minutes and loaded with flavor.
Brown the beef. Heat the olive oil in a Dutch oven or cooking pot over medium-high heat. Add the onion and cook, stirring for 3-4 minutes, or until soft. Add garlic and cook for 15 seconds or until fragrant. Add the beef and cook until browned, breaking down the lumps, about 6 to 8 minutes.
Season the beef. Add the chili seasoning and smoked paprika. Cook, stirring for 1 minute.
Add the rest of the ingredients. Stir in the diced green chilies, canned diced tomatoes, broth, bouillon powder, and tomato paste.
Cook. Bring to a boil, then reduce the heat and continue to cook for 10 minutes.
Add the beans and macaroni. Stir in the black beans and macaroni. Give it a good stir, then cook until the pasta is tender, about 8 minutes. Stir a few times while it cooks so the pasta does not stick to the bottom of the pot. Season to taste with salt and pepper.
Add the cheese. Stir in the cheddar cheese and remove the pot from the heat. Once the cheese is melted, stir in the lime juice.
Serve. Serve your chili mac warm, topped with pickled jalapenos, sour cream, shredded cheddar cheese, and chopped cilantro.
Notes
If you feel your chili mac is too thick, add some extra broth. If you want it to be thicker, then cook it for an extra 2-3 minutes once the pasta is cooked.
You can use Monterey Jack instead of cheddar cheese.
A bouillon substitute can be made with a mix of your favorite dried herbs, garlic powder, onion powder, salt, and a splash of soy sauce.
For extra flavor, add roasted corn kernels or serve chili mac with Cotija cheese on top.
