The Ultimate Crock Pot Chili Mac and Cheese Recipe

This recipe combines the savory, spiced heartiness of a classic chili with the creamy, decadent joy of macaroni and cheese. Using the slow cooker melds the flavors together over several hours, resulting in an incredibly rich and tender dish with minimal hands-on effort.

Ingredients

• For the Chili Base:
  • 1.5 lbs lean ground beef (90/10 recommended)
  • 1 large yellow onion, finely diced
  • 2 cloves garlic, minced
  • 1 (15-ounce) can of red kidney beans, rinsed and drained
  • 1 (15-ounce) can of pinto beans, rinsed and drained
  • 1 (28-ounce) can of crushed tomatoes
  • 1 (10-ounce) can of diced tomatoes with green chilies (like Rotel), undrained
  • 1 cup beef broth
  • 2 tablespoons chili powder
  • 1 tablespoon cumin
  • 1 teaspoon smoked paprika
  • 1 teaspoon dried oregano
  • 1/2 teaspoon salt (or to taste)
  • 1/2 teaspoon black pepper (or to taste)
  • 1 tablespoon olive oil (for browning the beef)
• For the Mac and Cheese Finish:
  • 2 cups (8 ounces) uncooked elbow macaroni
  • 1 (12-ounce) can evaporated milk
  • 2 cups (8 ounces) shredded sharp cheddar cheese
  • 1 cup (4 ounces) shredded Monterey Jack cheese

Ingredient Notes and Substitutions

This recipe is incredibly versatile. Here are some common and effective substitutions to tailor it to your pantry and preferences:

• Ground Meat: Don’t have ground beef? Ground turkey, ground chicken, or even spicy Italian sausage (casings removed) work wonderfully. If using a leaner meat like turkey, you may want to add a little extra olive oil when browning to prevent it from drying out.
• Beans: Feel free to swap the beans based on your preference. Black beans are a fantastic addition. If you’re not a fan of beans at all, you can simply omit them and add an extra half-pound of ground meat.
• Tomatoes: The crushed tomatoes create the rich base, while the diced tomatoes with green chilies add a subtle kick and texture. If you prefer a milder chili, you can use a can of regular petite diced tomatoes instead. For a smokier flavor, try fire-roasted diced tomatoes.
• Pasta: Elbow macaroni is classic, but any short, sturdy pasta will work well. Consider shells, rotini, cavatappi, or penne. The ridges and curves on these shapes are perfect for catching all the cheesy, meaty sauce.
• Cheese: The combination of sharp cheddar for flavor and Monterey Jack for meltiness is a winner, but feel free to experiment. Colby, Pepper Jack (for an extra kick), or a Mexican cheese blend are all excellent choices. For the best results, always buy a block of cheese and shred it yourself. Pre-shredded cheeses are often coated in anti-caking agents that can make your sauce gritty.
• Spice Level: This recipe has a mild to medium heat. To increase the spice, add a pinch of cayenne pepper, a finely diced jalapeño (add it with the onion and garlic), or a dash of your favorite hot sauce at the end. To make it milder for sensitive palates, use a mild chili powder and omit the diced tomatoes with green chilies.

Step-by-Step

Instructions

Follow these detailed steps to ensure your chili mac turns out perfectly creamy and flavorful every time.

Step 1: Brown the Meat and Aromatics

Heat the olive oil in a large skillet or Dutch oven over medium-high heat. Add the diced yellow onion and cook for 3-4 minutes until it begins to soften. Add the ground beef to the skillet. Break it apart with a spoon and cook until it’s fully browned, about 5-7 minutes. There should be no pink remaining. Add the minced garlic and cook for another minute until fragrant. This browning step is crucial—it develops a deep, savory flavor (the Maillard reaction) that you can’t achieve by just putting raw meat in the slow cooker. Once cooked, drain any excess grease from the skillet.

Step 2: Build the Chili Base in the Slow Cooker

Transfer the cooked beef and onion mixture to the basin of a 6-quart or larger slow cooker. Add the rinsed kidney beans, rinsed pinto beans, crushed tomatoes, undrained diced tomatoes with green chilies, and beef broth. Stir in all the spices: chili powder, cumin, smoked paprika, dried oregano, salt, and black pepper. Stir everything together until well combined.

Step 3: Slow Cook for Flavor Infusion

Place the lid on the slow cooker. Cook on LOW for 6-8 hours or on HIGH for 3-4 hours. The low and slow method is highly recommended as it gives the flavors more time to meld together into a rich, cohesive chili. The house will start to smell amazing after a few hours!

Step 4: Cook the Pasta

About 30 minutes before the chili cooking time is finished, cook the elbow macaroni in a separate pot of salted, boiling water according to the package directions for al dente. It’s important to cook it al dente (still with a slight bite) because it will continue to soften slightly when added to the hot chili. Once cooked, drain the pasta well but do not rinse it.

Pro-Tip: While some recipes call for cooking the pasta directly in the slow cooker, this can lead to mushy pasta and a starchy, gummy sauce. Cooking it separately guarantees the perfect texture for both the pasta and the chili.

Step 5: Combine and Melt for Creamy Perfection

Once the chili has finished its slow cooking time, turn the slow cooker to the “Keep Warm” setting or turn it off completely. Stir in the cooked and drained macaroni. Pour in the can of evaporated milk and stir until it’s fully incorporated. This is the secret to an ultra-creamy, stable sauce that won’t break or become oily.

Step 6: Add the Cheese

Add the shredded sharp cheddar and Monterey Jack cheeses to the slow cooker in handfuls, stirring gently after each addition until the cheese is completely melted and the sauce is smooth and glossy. Do not turn the heat back on high, as this can cause the cheese to separate. Let the chili mac sit for about 5-10 minutes to allow the sauce to thicken up slightly before serving.

Step 7: Taste and Serve

Give the finished chili mac a final taste and adjust the seasoning if necessary. It might need another pinch of salt or a dash of chili powder depending on your preference. Ladle into bowls and serve hot with your favorite toppings.

How to Serve Crock Pot Chili Mac

One of the best parts about chili mac is dressing it up with toppings. Setting up a “toppings bar” is a fun way for everyone in the family to customize their own bowl.

The Ultimate Toppings Bar

• For Creaminess:
  • A dollop of sour cream or plain Greek yogurt
  • Extra shredded cheddar cheese
  • Crumbled cotija cheese
• For a Fresh Bite:
  • Finely chopped fresh cilantro
  • Sliced green onions or chives
  • Diced red onion
  • Diced avocado
• For a Spicy Kick:
  • Sliced fresh or pickled jalapeños
  • A dash of your favorite hot sauce
  • A sprinkle of red pepper flakes
• For a Crunchy Texture:
  • Crushed Fritos or corn chips (a classic!)
  • Crispy fried onions
  • Crumbled saltine crackers

Perfect Side Dishes

While this is a complete one-pot meal, a simple side can round it out perfectly.

• Classic Cornbread: A slice of sweet, buttery cornbread is the quintessential partner for any chili. Use it to scoop up every last bit of the cheesy sauce.
• Simple Green Salad: A crisp salad with a light vinaigrette provides a refreshing contrast to the rich, hearty chili mac. Think mixed greens, cucumber, and cherry tomatoes.
• Garlic Bread: Cheesy garlic bread or simple toasted baguette slices are perfect for dipping.
• Steamed Vegetables: A side of simple steamed broccoli or green beans adds a healthy, green element to the meal.

Additional Tips for a Perfect Chili Mac

Here are five expert tips to take your slow cooker chili mac from great to absolutely unforgettable.

1. Don’t Skip the Browning Step
It might be tempting to dump all the ingredients into the slow cooker to save a pan, but browning the beef and onions first is non-negotiable for maximum flavor. This step creates a deep, caramelized, and savory foundation through the Maillard reaction that you simply cannot replicate otherwise. It’s the difference between a good chili mac and a great one.

2. The Secret to Ultra-Creamy Sauce
The key to a velvety, restaurant-quality cheese sauce is twofold. First, use evaporated milk instead of regular milk or heavy cream. Evaporated milk has been heated to remove about 60% of its water, which makes it more stable and less likely to curdle or break when combined with the acidic tomatoes in the chili. Second, always add the cheese at the very end with the heat turned off. High heat is the enemy of cheese sauce and can cause it to become grainy and oily. Stirring it in gently on the “warm” setting allows it to melt smoothly into the sauce.

3. Grate Your Own Cheese
While convenient, pre-shredded cheese from a bag is coated with starches like potato starch or cellulose to prevent clumping. These anti-caking agents can prevent the cheese from melting smoothly and can give your sauce a slightly gritty or powdery texture. Buying a block of cheddar and Monterey Jack and shredding it yourself takes only a few extra minutes and results in a significantly smoother, creamier, and more delicious sauce.

4. Master Your Leftovers
Chili mac is fantastic as leftovers, but it can thicken considerably in the refrigerator. To reheat, add a splash of milk or beef broth to a portion in a saucepan or microwave-safe bowl. Reheat gently over low heat on the stove or in the microwave at 50% power, stirring frequently, until warmed through. This will help loosen the sauce and bring it back to its original creamy consistency without making it oily.

5. Make-Ahead and Freezing Instructions
This recipe is a meal-prepper’s dream.

• To Make Ahead: You can prepare the entire chili portion of the recipe (steps 1-3) and store it in the refrigerator for up to 2 days. When you’re ready to eat, simply continue with steps 4-7.
• To Freeze: Chili mac freezes surprisingly well. Allow the finished dish to cool completely. Portion it into freezer-safe containers or bags. It can be frozen for up to 3 months. To reheat, thaw it overnight in the refrigerator and then gently reheat on the stovetop or in the microwave with a splash of milk or broth as described in the tip above.

Frequently Asked Questions (FAQ)

Q1: Can I make this chili mac recipe on the stovetop instead of a slow cooker?
A: Absolutely! To convert this recipe to the stovetop, brown the beef and onions in a large Dutch oven or stockpot. Add all the other chili ingredients (beans, tomatoes, broth, spices) and bring the mixture to a simmer. Reduce the heat to low, cover, and let it simmer for at least 1 hour, stirring occasionally, to allow the flavors to develop. Then, proceed with adding the separately cooked pasta, evaporated milk, and cheese as directed in the recipe.

Q2: My chili mac seems a little watery. How can I thicken it?
A: If your chili mac seems thinner than you’d like after adding the cheese, there are a few easy fixes. First, simply let it sit with the lid off for 10-15 minutes on the “warm” setting; it will naturally thicken as it cools slightly. If it’s still too thin, you can create a cornstarch slurry. Mix 1 tablespoon of cornstarch with 2 tablespoons of cold water until smooth. Stir this slurry into the chili mac and let it cook on “warm” for another 10 minutes until it thickens up. A third option is to simply stir in a bit more shredded cheese.

Q3: Can I use ground turkey or chicken instead of ground beef?
A: Yes, ground turkey or chicken are great leaner alternatives. When browning the meat, you may want to add an extra teaspoon of olive oil to prevent it from sticking or becoming dry. Because these meats are milder in flavor, you might also consider adding a teaspoon of Worcestershire sauce or soy sauce along with the beef broth to boost the umami and savory depth of the chili base.

Q4: Is it possible to cook the pasta directly in the slow cooker?
A: While it’s technically possible, it’s not recommended for the best texture. Uncooked pasta releases a lot of starch as it cooks, which can make the final sauce gummy or pasty. It is also very easy to overcook pasta in a slow cooker, resulting in mushy, unappealing noodles. Cooking the macaroni separately and stirring it in at the end ensures that both the pasta and the sauce have the perfect, distinct texture. It’s an extra step that is well worth the effort.

Q5: What are some ways to add hidden vegetables for picky eaters?
A: This recipe is fantastic for sneaking in extra nutrition. You can finely shred or dice carrots, zucchini, or bell peppers and add them to the skillet when you are cooking the onions. They will soften completely during the long slow cooking process and blend seamlessly into the chili base. You could also stir in a cup of puréed pumpkin (which pairs wonderfully with the chili spices) or a handful of fresh spinach at the very end; the spinach will wilt down and become nearly undetectable.
