Ingredients You’ll Need
Here’s what you’ll need to create this culinary masterpiece. Don’t worry, the list is short and sweet!

- 1 green bell pepper, chopped
- 2 cloves garlic, minced
- 1 (15-ounce) can diced tomatoes, undrained
- 1 (15-ounce) can kidney beans, rinsed and drained
- 1 (15-ounce) can black beans, rinsed and drained
- 1 (8-ounce) can tomato sauce
- 1 (4-ounce) can diced green chilies
- 1 tablespoon chili powder
- 1 teaspoon cumin
- 1/2 teaspoon smoked paprika
- 1/4 teaspoon cayenne pepper (optional, for added heat)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 4 cups cooked elbow macaroni
- 2 cups shredded cheddar cheese, divided
Ingredient Notes and Substitutions
- Ground Beef: You can substitute ground turkey or ground chicken for a leaner option.
- Beans: Feel free to use your favorite type of beans, such as pinto beans or chili beans.
- Cheese: Cheddar is classic, but you can also use Monterey Jack, Colby Jack, or a blend of cheeses.
- Pasta: Elbow macaroni is traditional, but you can use any small pasta shape, such as shells or rotini.
- Spice Level: Adjust the amount of chili powder and cayenne pepper to your liking. If you’re sensitive to heat, omit the cayenne pepper altogether.
- Vegetarian Option: Omit the ground beef and add an extra can of beans or a package of plant-based crumbles for a vegetarian version.
Step-by-Step Instructions
Now for the fun part! Follow these simple steps, and you’ll have a delicious Crock Pot Cheddar Chili Mac in no time.
- Brown the Ground Beef: In a large skillet, brown the ground beef over medium-high heat. Drain off any excess grease. This step is important because it develops a richer flavor in the chili. You’ll see the beef change from pink to brown and start to crumble.
- Sauté the Vegetables: Add the chopped onion and green bell pepper to the skillet and cook until softened, about 5 minutes. Add the minced garlic and cook for another minute until fragrant. The onions will become translucent and the peppers will soften slightly, releasing their aroma.
- Combine in the Slow Cooker: Transfer the browned ground beef and sautéed vegetables to the slow cooker.
- Add the Remaining Ingredients: Add the diced tomatoes, kidney beans, black beans, tomato sauce, diced green chilies, chili powder, cumin, smoked paprika, cayenne pepper (if using), salt, and black pepper to the slow cooker. Stir well to combine. The mixture should look thick and colorful.
- Cook on Low: Cover the slow cooker and cook on low for 6-8 hours, or on high for 3-4 hours. This slow cooking process allows the flavors to meld together beautifully.
- Stir in the Macaroni and Cheese: Stir in the cooked elbow macaroni and 1 1/2 cups of the shredded cheddar cheese. Stir until the cheese is melted and the pasta is evenly coated. The chili mac will become creamy and cheesy as the cheese melts.
- Top with Cheese and Serve: Sprinkle the remaining 1/2 cup of shredded cheddar cheese over the top. Cover and let the cheese melt for a few minutes. Serve hot and enjoy!
Serving Suggestions
This Crock Pot Cheddar Chili Mac is delicious on its own, but here are a few serving suggestions to take it to the next level:
- Toppings: Top with sour cream, shredded cheese, chopped green onions, or a dollop of guacamole.
- Side Dishes: Serve with a side of cornbread or a simple green salad.
- Extra Heat: Add a few dashes of your favorite hot sauce for an extra kick.
Success Tips for Perfect Crock Pot Chili Mac
Want to ensure your Crock Pot Cheddar Chili Mac is a resounding success? Here are my top tips for achieving chili mac perfection every time:
- Don’t Skip the Browning Step: Browning the ground beef is crucial for developing a rich, savory flavor. It adds depth that you just can’t get by skipping this step.
- Adjust the Spices to Your Taste: The beauty of this recipe is that it’s easily customizable. Don’t be afraid to adjust the amount of chili powder, cumin, and cayenne pepper to suit your family’s preferences.
- Don’t Overcook the Pasta: To prevent mushy pasta, cook it al dente before adding it to the slow cooker. It will continue to cook slightly in the chili, so you want to make sure it doesn’t get overcooked.
- Add Cheese at the End: Adding the cheese at the end ensures that it melts beautifully and doesn’t become greasy.
- Consider a Liner: For easy clean-up, use a slow cooker liner. It’s a game-changer!
Make-Ahead and Freezing Instructions
This Crock Pot Cheddar Chili Mac is a great make-ahead meal. You can prepare the chili base up to 2 days in advance and store it in the refrigerator. When you’re ready to serve, simply add the cooked macaroni and cheese, heat through, and enjoy.
To freeze, let the chili mac cool completely. Transfer it to an airtight container or freezer bag and freeze for up to 3 months. When ready to eat, thaw overnight in the refrigerator and reheat on the stovetop or in the microwave.
Variations and Adaptations
Want to put your own spin on this classic recipe? Here are a few ideas to get you started:
- Spicy Chili Mac: Add a chopped jalapeño pepper or a pinch of red pepper flakes for extra heat.
- Mexican Chili Mac: Add a can of corn and a packet of taco seasoning for a south-of-the-border twist.
- White Chicken Chili Mac: Substitute ground chicken for the ground beef and use a can of white beans instead of kidney beans and black beans.
