Quick Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 2–3 hours on LOW in the slow cooker, plus pasta cooking time
• Total Time: Approximately 2 hours 30 minutes
• Servings: 4
• Difficulty: Easy
• Cuisine: American, Tex-Mex-inspired
• Course: Dinner, Main Course

Ingredients

• 1 lb lean ground beef, browned and drained
• 1 cup uncooked macaroni, cooked al dente
• 15 oz can mild chili beans, undrained
• 10.5 oz can diced tomatoes with green chiles, drained
• 1.5 teaspoons chili powder
• 1 teaspoon garlic salt
• 1 cup shredded cheddar cheese

Step-by-Step Instructions

Step 1: Brown the Ground Beef

Heat a large skillet over medium-high heat. Add the ground beef and cook for about 6–8 minutes, breaking it into small crumbles as it browns.

Drain the excess fat and transfer the cooked beef to the slow cooker. Browning the beef first adds flavor and helps keep the finished dish from becoming greasy.

Step 2: Add the Chili Ingredients

Add the undrained mild chili beans, drained diced tomatoes with green chiles, chili powder, and garlic salt to the slow cooker.

Stir everything together until the seasonings are evenly distributed throughout the beef and beans.

Step 3: Slow Cook the Chili Mixture

Cover and cook on LOW for approximately 2–3 hours, stirring once if convenient, until the mixture is hot and the flavors have blended.

Because the beef is already cooked, this step is mainly for combining the flavors rather than cooking the meat from raw.

Step 4: Cook the Macaroni

While the chili mixture cooks, bring a pot of salted water to a boil. Add the macaroni and cook according to the package instructions, stopping when the pasta is just al dente.

Drain the macaroni well. Avoid overcooking it, since the pasta will soften further when mixed with the hot chili.

Step 5: Stir in the Macaroni

Add the cooked macaroni to the slow cooker and stir gently until the pasta is coated in the chili mixture.

If the mixture seems too thick, add a small splash of water or beef broth to loosen it. Avoid adding too much liquid at once.

Step 6: Add the Cheddar Cheese

Sprinkle the shredded cheddar cheese over the chili mac. Stir until the cheese melts and coats the macaroni, or leave a little on top for a cheesy finish.

Cover for another 5–10 minutes if needed to help the cheese melt. Once everything is hot and creamy, turn off the slow cooker.

Step 7: Serve Warm

Spoon the Crock Pot Cheddar Chili Mac into bowls and serve immediately. Add extra shredded cheddar, sliced green onions, or a dollop of sour cream if desired.

For the best texture, avoid leaving the pasta in the slow cooker on the warm setting for a long time.

Recipe Tips for Success

• Brown and drain the beef: This improves the flavor and reduces excess grease.
• Cook pasta separately: Adding dry macaroni directly to the slow cooker can make the dish too thick or leave the pasta unevenly cooked.
• Stop at al dente: Slightly firm pasta holds its shape better when mixed with the chili.
• Drain the tomatoes: The recipe calls for drained tomatoes, which helps control the amount of liquid.
• Use freshly shredded cheese: Cheese shredded from a block often melts more smoothly than pre-shredded cheese.
• Taste before adding more salt: Garlic salt and canned chili beans may already contain plenty of sodium.
• Add pasta near serving time: This helps prevent the macaroni from absorbing too much sauce and becoming mushy.

Ingredient Substitutions

• Ground beef: Ground turkey or ground chicken can replace the beef. Brown thoroughly before adding to the slow cooker.
• Macaroni: Small shells, rotini, or elbow pasta alternatives work well. Cook separately until al dente.
• Chili beans: Use pinto beans or kidney beans with a little extra chili seasoning if chili beans are unavailable.
• Diced tomatoes with green chiles: Regular diced tomatoes can be used with a small amount of canned green chiles.
• Cheddar cheese: Monterey Jack, Colby Jack, or a Mexican-style cheese blend are good alternatives.
• Garlic salt: Replace it with garlic powder and salt, adjusting the amounts to taste.
• Mild chili beans: Use a spicier variety if you prefer a bolder chili flavor.

Recipe Variations

Spicy Chili Mac

Use hot chili beans, add extra chili powder, or stir in a pinch of cayenne pepper. Diced jalapeños also add a fresh kick.

Extra-Cheesy Chili Mac

Add another 1/2 cup of shredded cheddar or mix in Monterey Jack for a creamier, cheesier finish.

Chili Mac with Vegetables

Stir in diced bell pepper or finely chopped onion with the beans and tomatoes. You can also add cooked corn for sweetness and texture.

Creamy Cheddar Chili Mac

Stir in 2–3 tablespoons of cream cheese or a small splash of milk with the cheddar. Add gradually so the sauce stays thick and smooth.

Turkey Chili Mac

Replace the ground beef with lean ground turkey. Brown it in a skillet before adding it to the slow cooker, then continue with the recipe as written.

Storage and Reheating

Refrigeration: Transfer leftovers to an airtight container and refrigerate within two hours. Use within 3–4 days.

Freezing: You can freeze the cooled chili mac in freezer-safe containers for up to 2 months for best quality. The macaroni may soften after thawing, so freezing the chili mixture separately and adding freshly cooked pasta later gives the best texture.

Stovetop reheating: Warm leftovers in a saucepan over medium-low heat, stirring gently. Add a splash of water or beef broth if the pasta has absorbed too much sauce.

Microwave reheating: Place a serving in a microwave-safe bowl and heat in short intervals, stirring between each one. Add a little liquid if needed.

Avoid prolonged reheating or keeping the finished pasta warm for hours, as this can make the macaroni overly soft.

Serving Suggestions

Crock Pot Cheddar Chili Mac is filling on its own, but these sides make it an even more satisfying dinner:

• Steamed green beans or broccoli
• Roasted corn

For a simple family meal, serve a generous bowl with a crisp green salad and warm garlic bread.

Frequently Asked Questions

Can I put uncooked macaroni directly into the slow cooker?

It’s better to cook the macaroni separately for this recipe. Dry pasta absorbs liquid as it cooks, which can change the consistency of the chili mixture and make the pasta unevenly tender.

Do I need to cook the ground beef first?

Yes. Brown the ground beef in a skillet and drain excess fat before adding it to the slow cooker. This gives the dish better flavor and helps reduce grease.

Can I cook this recipe on HIGH?

Yes. Because the beef is already cooked, you can cook the chili mixture on HIGH for approximately 1–1.5 hours, checking that it is hot and the flavors have blended. Add the cooked pasta and cheese near the end.

How do I stop the macaroni from becoming mushy?

Cook it separately until just al dente, drain it well, and stir it into the chili mixture shortly before serving. Avoid leaving the finished dish on the warm setting for an extended period.

Can I make Crock Pot Cheddar Chili Mac ahead of time?

Yes. Prepare the chili mixture ahead and refrigerate it. When ready to serve, reheat it thoroughly, cook the macaroni separately, and stir in the pasta and cheese.

Can I use a different type of cheese?

Absolutely. Colby Jack, Monterey Jack, or a Mexican-style shredded cheese blend can replace cheddar. Choose a cheese that melts well for a smooth finish.

Is this recipe spicy?

The recipe is generally mild because it uses mild chili beans and a modest amount of chili powder. For a spicier version, use hot chili beans or add jalapeños and cayenne pepper.

What should I do if the chili mac is too thick?

Stir in a small amount of warm beef broth or water until it reaches your preferred consistency. Add it gradually so the dish doesn’t become watery.

Final Thoughts

Crock Pot Cheddar Chili Mac combines savory ground beef, seasoned chili beans, tomatoes with green chiles, tender macaroni, and melted cheddar in one comforting dinner. Cooking the chili mixture in the slow cooker makes preparation simple, while adding the pasta near the end helps preserve its texture.

Keep the toppings simple or customize each bowl with sour cream, green onions, or extra cheese. It’s an easy, flexible meal for busy evenings when you want something warm and satisfying.
