Ingredients for Chilli Mac Crock Pot

Simple pantry staples meet slow cooker magic for this hearty dish.

The beef is the backbone here. 80/20 ground chuck gives the richest flavor—leaner blends can dry out during long cooking. I grab mine from Costco for bulk savings, but any supermarket works. For the beans, Bush’s Best or store-brand are both solid choices (just drain and rinse well). The pasta soaks up all that cheesy chili goodness, so use Barilla or De Cecco for consistent texture.

No chili powder? Combine 1 tbsp smoked paprika + 1 tsp each cumin and cayenne for a close match. Fresh out of bell pepper? Celery adds similar crunch. The cheeses can be swapped—Colby Jack or pepper jack add nice variations. Using pre-shredded cheese? It works in a pinch (but melts less smoothly). Want more heat? Add a diced jalapeño with the onions.

Leftovers keep 4-5 days in the fridge, but honestly it’s best fresh. Freeze portions for up to 3 months—just thaw overnight before reheating. The flavors deepen after a day, so make extra for lunch tomorrow (it reheats beautifully).

Step-by-Step Instructions for Chilli Mac Crock Pot

Here’s the hands-off method that turns simple ingredients into a crowd-pleasing meal with minimal effort.

Step 1: Brown the Ground Beef with Aromatics

In a large skillet over medium-high heat, cook the 1 lb Ground Beef until it loses its pink color and begins to brown, breaking it into small crumbles with a wooden spoon. This takes about 5-7 minutes.

Add the finely diced Yellow Onion, diced Bell Pepper, and minced 3 cloves Garlic Cloves to the skillet. Cook for another 3-4 minutes until the vegetables soften and the onion becomes translucent. Drain excess fat if needed, but leave about 1 tablespoon for flavor.

Step 2: Combine All Ingredients in the Crock Pot

Transfer the browned beef and vegetable mixture to your crock pot. Add the 2 cups Elbow Macaroni, 1 can Black Beans, 1 can Kidney Beans, 1 can Diced Tomatoes (with juices), 1 can Tomato Sauce, 2 tbsp Chili Powder, 1 tsp Ground Cumin, and 1 tsp Dried Oregano.

Pour in the 2 cups Beef Broth and stir everything together until evenly distributed. The liquid should just cover the pasta and beans—if it looks dry, add a splash more broth.

Step 3: Cook on Low Until Pasta is Tender

Cover the crock pot and cook on low heat for 2.5 to 3 hours. Avoid lifting the lid during cooking to prevent heat loss and ensure even cooking. The chilli mac is ready when the elbow macaroni is tender but still slightly firm to the bite.

If you notice the mixture drying out before the pasta finishes, stir in ¼ cup of hot water or additional beef broth. The beans and pasta will absorb liquid as they cook, so this adjustment keeps everything perfectly saucy.

Step 4: Add Cheese and Finish

Once the pasta is cooked, uncover and stir in 2 cups Cheddar Cheese and 1 cup Monterey Jack Cheese. The residual heat will melt the cheese into a gooey, golden layer that binds everything together. Let it sit uncovered for 5 minutes to allow the cheeses to fully incorporate.

Taste and adjust seasoning if needed—sometimes a pinch of salt or extra chili powder enhances the flavors. The final texture should be creamy and thick, with the pasta fully coated in the rich, cheesy sauce.

Essential Equipment for Great chilli mac crock pot

Slow Cooker Basics

I always recommend a 6-quart crock pot for this dish—it’s the perfect size for 4 servings without overcrowding. My go-to is the Hamilton Beach Set & Forget, which has programmable settings and a locking lid for easy transport to potlucks. 🔥

Skillet for Browning

A 12-inch stainless steel skillet gives you plenty of room to brown the 1 lb Ground Beef and sauté veggies without steaming them. I use my All-Clad for even heat distribution, but any heavy-bottomed pan works.

Wooden Spoon

Break up the beef with a flat wooden spoon—it won’t scratch your skillet and helps create those perfect crumbles. Avoid metal spoons on non-stick surfaces to preserve your cookware.

Measuring Tools

Accurate measurements matter here. I keep a set of OXO Good Grips measuring spoons and cups in my drawer for the 2 tbsp Chili Powder and other spices. A liquid measuring cup ensures your 2 cups Beef Broth is precise.

Cheese Grater

Freshly shredded cheese melts better than pre-shredded. I use a box grater for the 2 cups Cheddar Cheese and 1 cup Monterey Jack Cheese—the fine holes give you perfect meltability. Block cheese from Costco works great for this.

Serving Essentials

Have a large serving spoon ready for dishing this out. The creamy texture sticks together, so a spoon with a deep bowl works best. I also keep small bowls nearby for toppings like sour cream or green onions. 💛
