Crock Pot Cheddar Chili Mac is the ultimate cozy dinner when you need something hearty that does not take much effort. This dish brings together tender noodles hearty chili beans and melty cheese for a one pot meal that always disappears fast at my table
My family first tried this on a chilly weeknight and my kids were actually fighting over the leftovers the next day I love how it fills the house with such a comforting smell
Ingredients
- Lean ground beef: Use fresh beef with little excess fat for a rich meaty flavor and lighter result
- Uncooked macaroni: Choose elbow macaroni and cook just until al dente so it does not become mushy later
- Mild chili beans: Canned and undrained so the sauce is thick and has extra flavor
- Diced tomatoes with green chiles: Look for canned tomatoes with a mild kick for depth and tang
- Chili powder: Adds classic chili flavor and warmth choose a fresh jar for bold taste
- Garlic salt: Brings seasoning and complements the beef and beans
- Shredded cheddar cheese: Go for a sharp cheddar that melts well for creamy pockets of cheese throughout
When shopping make sure beans are not past their shelf life and opt for block cheese to shred yourself for the best melting
Step-by-Step Instructions
- Brown the Beef:
- In a skillet cook the ground beef thoroughly over medium heat breaking into small crumbles and draining any grease. This keeps the chili mac rich but not greasy
- Prepare the Macaroni:
- Boil macaroni in salted water until just al dente. Drain and set aside. Slightly undercooked pasta works best as it will finish cooking in the crock pot and absorb flavors
- Mix the Ingredients:
- Combine browned beef cooked macaroni chili beans with liquid drained diced tomatoes chili powder and garlic salt in your four quart slow cooker. Stir until everything is evenly mixed so flavors blend
- Top with Cheese:
- Sprinkle shredded cheddar in an even layer over the mixture. This gives a gooey cheesy top that families love
- Slow Cook:
- Cover slow cooker. Cook on low for about two hours or high for one to one and a half hours. If your slow cooker tends to heat unevenly rotate the insert halfway through for even cooking

My favorite part is always the gooey cheese crust on top. I remember one birthday when my youngest asked for “chili mac pie” with extra cheese and we laughed the entire night as we scooped out stretchy cheesy servings together
Storage Tips
Let leftovers cool then store in an airtight container in the fridge for up to four days. If you want to freeze it portion into freezer safe bags flatten and lay flat for up to two months. I usually reheat it in the microwave or on the stovetop with a splash of water to bring back the creamy texture
Ingredient Substitutions
Ground turkey or chicken works just as well if you want it lighter. Swap cheddar for Monterey Jack or even pepper jack for more heat. For a vegetarian option use a plant based ground and extra beans instead of beef
Serving Suggestions
Serve it with a fresh green salad or garlic bread to soak up extra sauce. I like adding a dollop of sour cream or some chopped green onions on top for a little extra zing and color

Cultural Notes
Chili mac is an old American classic often served at family gatherings or school lunches. The combo of pasta and chili brings together the best of Midwest comfort food and Tex Mex flavors which is probably why it feels so nostalgic and homey
