Ingredients You’ll Need
- Lean ground beef: Brown it first for richer flavor and better texture, draining excess fat keeps the final dish from being greasy.
- Yellow onion: Diced finely so it melts into the sauce, yellow onions offer a perfect balance of sweetness and savory depth.
- Garlic: Fresh minced cloves are best here, they add a pungent aromatic base that infuses the entire pot.
- Chili powder: This is your primary seasoning blend, look for a good quality one for the most authentic chili flavor.
- Ground cumin: Adds a warm, earthy note that’s essential to any great chili recipe.
- Smoked paprika: Provides a subtle smokiness that mimics longer cooking times, sweet paprika works in a pinch.
- Kosher salt: Its coarse grains season evenly and help draw out the flavors of the other ingredients.
- Black pepper: Freshly cracked pepper adds a gentle heat and complexity to the seasoning profile.
- Crushed tomatoes: These form the thick, rich body of your chili sauce, no need to chop.
- Tomato sauce: Adds smooth, concentrated tomato flavor and helps create the perfect saucy consistency.
- Red kidney beans: Drained and rinsed to control sodium, they add protein and that classic chili texture.
- Dry elbow macaroni: The classic mac and cheese shape holds the sauce so well in every bite.
- Beef broth: This liquid is crucial for cooking the pasta right in the pot, use low-sodium if you prefer.
- Sharp cheddar cheese: Freshly shredded from a block melts smoother and creamier than pre-shredded varieties.
- Sliced green onions: A fresh, crisp garnish that adds color and a mild oniony finish.
- Sour cream: A cool, tangy dollop on top helps balance the richness and spice beautifully.
- Diced jalapeños: For those who love extra heat, they add a fresh, vegetal kick right at the end.
How to Make It
Brown the Beef and Aromatics:
Start by heating a large skillet over medium-high heat and cooking your ground beef until it’s fully browned and no longer pink. This step isn’t just about cooking the meat, it’s about building a foundation of deep, savory flavor through caramelization. Draining any excess fat afterward gives you control over the final texture, keeping your chili mac rich but not greasy. You’ll be glad you took these few extra minutes.
Sauté the Onion and Garlic:
Add the diced onion and minced garlic right into the skillet with the cooked beef. Give everything a good stir and let it cook for a few minutes until the onion softens and becomes fragrant. This softens their raw bite and allows their sugars to mellow, which sweetens the entire dish. You’re essentially creating a flavor base that will permeate every single component in the slow cooker.
Transfer and Season:
Scoop the beef and onion mixture into your six-quart slow cooker. Sprinkle all the dried spices—the chili powder, cumin, smoked paprika, salt, and pepper—directly over the top. Stir everything together really well right now to ensure each bit of meat is coated. This helps the spices toast slightly and wake up their oils before they hit the liquid, maximizing their impact.
Build the Chili Base:
Pour in your crushed tomatoes, tomato sauce, and the drained kidney beans. Stir it all up until the colors and textures are fully combined. At this stage, it’ll look very saucy and loose, but don’t worry. The long, slow cook time ahead will concentrate these flavors and thicken the sauce beautifully, and the beans will become wonderfully tender.
The Long Simmer:
Cover the slow cooker and let the magic happen. You can cook it on low for about six hours if you’re out for the day, or on high for around three if you need it faster. This extended simmering is where the flavors truly marry and deepen, transforming simple ingredients into a complex, hearty chili. Your kitchen will smell incredible.
Cook the Pasta:
About thirty minutes before you plan to eat, stir in the dry elbow macaroni and pour in the beef broth. Give it another good stir to make sure the pasta is submerged, then put the lid back on. Cook it on high for that half hour—this gives the pasta just enough time to become perfectly al dente and absorb the flavorful liquid without turning to mush.
Finish with Cheese:
Once the pasta is tender, turn off the slow cooker. Stir in the two cups of shredded cheddar cheese until it’s completely melted and creates a luscious, creamy sauce that coats every noodle and bean. The residual heat is plenty to melt the cheese smoothly. Let it sit for just a couple minutes off the heat to thicken up slightly before you serve.
Garnish and Serve:
Ladle the hot chili mac into bowls and top with any of your favorite garnishes. A sprinkle of green onions adds freshness, a dollop of sour cream brings cool tang, and diced jalapeños give a welcome kick. This is where everyone at the table can make their bowl just right for them.

Storage Tips
Let any leftover Crock Pot chili mac cool completely before transferring it to an airtight container, where it’ll stay fresh in your fridge for up to four days. When you’re ready to reheat, just scoop a portion into a bowl and warm it gently in the microwave, stirring halfway through, or on the stovetop over low heat with a tiny splash of broth or water to loosen it up. You can also freeze portions in freezer-safe containers for about three months; thaw it overnight in the refrigerator before reheating it slowly on the stove.
Ingredient Substitutions
You’ve got plenty of room to make this chili mac your own. If you don’t eat beef, ground turkey, chicken, or even a plant-based ground meat alternative work beautifully with the same cooking method. Feel free to swap the kidney beans for pinto beans, black beans, or even a can of drained corn for a different twist. If you want a different cheese, a Monterey Jack blend or even a pepper jack for more spice would be fantastic, and for a gluten-free version, just use your favorite gluten-free elbow pasta and check that your broth is certified GF.
Serving Suggestions
This hearty chili mac is a complete meal all on its own, but I love serving it with a piece of warm, buttery cornbread or a few slices of garlic toast for scooping up every last bit. A simple, crisp green salad with a tangy vinaigrette on the side cuts through the richness perfectly. For a real family-style feast, set out bowls of extra shredded cheese, sliced jalapeños, crushed tortilla chips, and more sour cream so everyone can build their ultimate bowl.
Cultural Context
This dish is a fantastic example of American comfort food fusion, taking two beloved classics and merging them into one easy, crowd-pleasing pot. Chili, with its roots in Tex-Mex cuisine, and macaroni and cheese, a staple with European origins, come together in a way that feels uniquely modern and practical for today’s busy home cooks. It embodies that set-it-and-forget-it slow cooker philosophy that became so popular in the latter half of the 20th century, perfect for the way we live now. It’s less about formal tradition and more about creating a new, delicious tradition of hassle-free, satisfying dinners that bring everyone to the table.
Pro Tips
- Don’t skip browning the beef—it adds a crucial flavor layer
- If your chili mac looks too liquidy, cook it uncovered for the last 10 minutes
- Always shred your own cheese from a block for the creamiest melt
- I prefer low and slow cooking for the deepest flavor development
