Ingredients

For the Chili Base:

• 1 lb (450 g) ground beef (80/20 lean recommended)
• 1 medium yellow onion, chopped
• 2 cloves garlic, minced
• 1 (14.5 oz / 411 g) can diced tomatoes, undrained
• 1 (15 oz / 425 g) can tomato sauce
• 1 (15 oz / 425 g) can kidney beans, rinsed and drained
• 1 (15 oz / 425 g) can black beans, rinsed and drained
• 1 cup (240 ml) beef broth
• 2 tbsp (30 ml) chili powder
• 1 tsp (5 ml) ground cumin
• 1/2 tsp (2.5 ml) dried oregano
• 1/4 tsp (1.25 ml) cayenne pepper (optional, for heat)
• Salt and freshly ground black pepper to taste

For the Mac and Cheese:

• 2 cups (200 g) elbow macaroni, uncooked
• 1 cup (240 ml) milk (whole or 2% recommended)
• 2 cups (220 g) shredded sharp cheddar cheese
• 1 cup (110 g) shredded Monterey Jack cheese (or a cheddar blend)

Optional Toppings:

• Shredded cheese
• Sour cream or Greek yogurt
• Chopped green onions or fresh cilantro
• Crushed tortilla chips

Ingredient Notes

• Ground Beef: Using 80/20 ground beef provides great flavor. You can also use ground turkey or chicken for a leaner option. Just be sure to brown and drain it well.
• Beans: Kidney and black beans are classic chili additions. Feel free to swap them for pinto beans or use just one type. Always rinse canned beans to reduce sodium.
• Broth and Milk: Beef broth forms the flavorful liquid base for the chili. Whole milk or 2% milk adds creaminess to the macaroni and cheese. Avoid skim milk as it may not provide enough richness.
• Cheese: Sharp cheddar provides a classic robust flavor, while Monterey Jack melts smoothly and adds a milder, creamy texture. A Mexican blend or Colby Jack would also work well. Freshly shredded cheese melts better than pre-shredded.
• Spices: Adjust the chili powder and cayenne pepper to your preferred spice level. For a milder version, omit the cayenne.

Equipment You’ll Need

• Large slow cooker (6-quart or larger)
• Large skillet (for browning meat)
• Measuring cups and spoons
• Can opener
• Stirring spoon or spatula

How to Make Slow Cooker Chili Mac and Cheese

This recipe is designed for ease, bringing together the best of chili and mac and cheese with minimal fuss.

1. Brown the Ground Beef:

   In a large skillet over medium-high heat, brown the ground beef until no longer pink, breaking it apart with a spoon. Drain off any excess grease. Transfer the browned beef to your 6-quart or larger slow cooker.

2. Sauté Aromatics (Optional but Recommended):

   If desired, in the same skillet (after draining grease), add the chopped onion and cook until softened, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant. Transfer the onion and garlic to the slow cooker with the beef.

3. Combine Chili Ingredients:

   To the slow cooker, add the diced tomatoes (undrained), tomato sauce, rinsed and drained kidney beans, rinsed and drained black beans, beef broth, chili powder, ground cumin, dried oregano, and cayenne pepper (if using). Stir everything together until well combined. Season with salt and pepper to taste.

   

4. Slow Cook the Chili:

   Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours. The chili should be bubbly and fragrant, with flavors fully developed.

5. Add Macaroni and Milk:

   Once the chili has cooked, stir in the uncooked elbow macaroni and milk. Ensure the macaroni is mostly submerged in the liquid. If the mixture seems too thick, you can add an extra splash of broth or water.

6. Continue Cooking:

   Cover and continue to cook on high for an additional 30-45 minutes, or until the macaroni is tender. Stir occasionally during this stage to prevent the pasta from sticking to the bottom.

   

7. Stir in Cheese:

   Once the macaroni is tender, turn off the slow cooker or set it to the ‘warm’ setting. Stir in the shredded sharp cheddar cheese and Monterey Jack cheese until fully melted and creamy. The residual heat will melt the cheese beautifully.

   

8. Serve:

   Ladle into bowls and serve hot with your favorite toppings! Enjoy this comforting and cheesy meal.

Pro Tips for the Best Results

• Don’t Skip Browning the Meat: While it adds a small extra step, browning the ground beef before adding it to the slow cooker develops much deeper flavor and a better texture for your chili base. Drain the fat for a less greasy dish.
• Freshly Shredded Cheese is Key: Pre-shredded cheeses often contain anti-caking agents that can make them melt less smoothly. Take the extra minute to shred your own block of cheese for the creamiest results.
• Add Pasta Last: Resist the urge to add the macaroni at the beginning of the cook time. Pasta cooked for too long in the slow cooker will become mushy. Adding it during the last 30-45 minutes ensures it cooks perfectly al dente.
• Stir the Pasta: When the pasta is cooking, give it a stir every 15 minutes or so to prevent it from clumping together or sticking to the bottom of the slow cooker.
• Adjust Liquid as Needed: Different slow cookers cook at different rates, and some pasta absorbs more liquid than others. If your chili mac seems too dry after adding the pasta, add a little extra beef broth or milk, a quarter cup at a time, until it reaches your desired consistency.
• Spice It Up: If you love heat, consider adding a diced jalapeño (seeds removed for less heat) with the onions or a pinch more cayenne pepper.

Common Mistakes to Avoid

• Overcooking the Pasta: The most common pitfall! Adding pasta too early results in a mushy, unappetizing texture. Always add it towards the end.
• Not Draining Grease: If you don’t drain the grease after browning the beef, your chili mac can become oily and heavy.
• Using Low-Fat Dairy for Cheese Sauce: While some low-fat options work, using whole milk or 2% milk and full-fat cheese ensures a richer, creamier mac and cheese component.
• Skipping the Stir: Neglecting to stir the pasta while it cooks can lead to clumps or sticking, resulting in unevenly cooked macaroni.
• Under-Seasoning: Taste and adjust! Chili mac needs robust seasoning. Don’t be afraid to add more salt, pepper, or chili powder if the flavors seem flat after cooking.

Variations & Substitutions

• Meat Options: Swap ground beef for ground turkey, ground chicken, or even a plant-based crumble for a vegetarian version.
• Bean Varieties: Experiment with pinto beans, cannellini beans, or even a mix of several types.
• Spice Level: For extra heat, add a pinch of red pepper flakes, a dash of hot sauce, or a finely diced habanero with the aromatics. For a milder version, omit the cayenne.
• Cheese Blends: Get creative with your cheese! Pepper Jack for a spicy kick, smoked gouda for a deeper flavor, or a Colby Jack blend are all great options.
• Add Veggies: Stir in a diced bell pepper (any color) with the onions or a handful of frozen corn during the last hour of cooking for added nutrients and color.
• Smoky Flavor: A teaspoon of smoked paprika can add a delicious smoky depth to the chili base.

Serving Suggestions

Slow Cooker Chili Mac and Cheese is a complete meal on its own, but a few fresh additions can take it over the top!

• Classic Toppings: A dollop of sour cream or plain Greek yogurt, extra shredded cheese, fresh chopped green onions, or cilantro are always welcome.
• Crunchy Element: Crushed tortilla chips, corn chips (like Fritos), or even a side of cornbread for dipping add a satisfying crunch.
• Fresh Sides: A simple green salad with a light vinaigrette or some steamed broccoli can provide a fresh contrast to the rich chili mac.
• Heat Factor: Offer a bottle of your favorite hot sauce on the side for those who like to turn up the heat.

Storage & Reheating

This Slow Cooker Chili Mac and Cheese is fantastic for meal prep and leftovers!

• Refrigerator Storage: Allow the chili mac to cool completely, then transfer it to an airtight container. It will keep well in the refrigerator for 3-4 days.
• Freezer Suitability: Yes, this dish freezes well! Once cooled, transfer portions to freezer-safe containers or heavy-duty freezer bags, leaving a little headspace. It can be frozen for up to 3 months. Thaw overnight in the refrigerator before reheating.
• Reheating: For best results, reheat individual portions in the microwave until heated through, stirring halfway. You may want to add a splash of milk or broth during reheating to restore creaminess, as the pasta can absorb more liquid as it sits. For larger quantities, reheat gently on the stovetop over low heat, stirring frequently, adding liquid as needed.

FAQ

Can I make this chili mac ahead of time?

While the pasta is best cooked fresh, you can definitely prepare the chili base ahead of time. Cook the chili through step 4, then refrigerate for up to 3 days. When ready to serve, reheat the chili in the slow cooker or on the stovetop, then add the macaroni and milk, and continue with steps 5-7.

Can I use a different type of pasta?

Yes, small pasta shapes like ditalini, small shells, or rotini would also work. Adjust cooking time as needed, as different pasta shapes may cook at slightly different rates.

Why did my pasta turn out mushy?

The most common reason for mushy pasta is adding it too early or cooking it for too long. Ensure you add the macaroni only during the last 30-45 minutes of cooking and check for tenderness. Overcooking can also happen if your slow cooker runs very hot.

How can I make this dish spicier?

To increase the heat, add more cayenne pepper, a pinch of red pepper flakes, or a finely diced jalapeño or serrano pepper when sautéing the onions. You can also serve with hot sauce.

What if my chili mac is too thick or too thin?

If it’s too thick after adding the pasta, stir in extra beef broth or milk a quarter cup at a time until it reaches your desired consistency. If it’s too thin, ensure the pasta has had enough time to absorb liquid, or cook uncovered for a short period to allow some liquid to evaporate (though this is less common with this recipe).

Can I make this vegetarian?

Absolutely! Omit the ground beef and use a plant-based ground crumble or extra beans (like an additional can of kidney or pinto beans). Replace beef broth with vegetable broth. The rest of the recipe can remain the same.
