One pot chili mac is my cozy answer for busy nights when everyone wants something filling and cheesy in a hurry. Hearty beef, tender pasta, and a just-right kick of chili spice come together in a single pot for a meal even picky eaters will happily devour. I find myself pulling out this recipe on chilly evenings when time is short but comfort food is very much needed.

Every time I make this, someone always sneaks seconds before the pan is fully cool. When my son asked for it to be packed for his school lunch the next day, I knew it was an instant classic in our house.

Ingredients

  • Ground beef: provides hearty flavor and protein. Choose eighty five percent lean for the best balance of juiciness and rich taste
  • Yellow onion: diced for aromatics. Go for a firm onion with dry skin for best freshness
  • Beef broth: helps cook the pasta and punch up savory notes. Use low sodium if you prefer less salt
  • Elbow pasta: classic shape for chili mac but shells or rotini work well too. Pick a pasta with good structural integrity so it keeps a nice bite
  • Chili seasoning: blends make this effortless. Look at the ingredient list for one with real spices rather than mostly salt
  • Petite diced tomatoes: add acidity and a juicy texture. Pick a can with bright color and no added sugar
  • Chili beans or chili starter: bring bonus flavor and texture. Check for tender beans and a sauce that fits your preferred spice level
  • Tomato sauce: marries all the flavors together. Puree style is key for a creamy consistency
  • Cheddar cheese: shredded for melting. I always grab a block and shred it myself for the smoothest melt

Step-by-Step Instructions

Brown the Beef and Onion:
Use a large skillet or pot set over medium high heat. Cook ground beef and diced onions together stirring regularly until the beef loses its pink color and turns brown all over. This usually takes seven to eight minutes. Carefully drain off any extra grease to keep the final dish from getting heavy.
Build the Chili Base:
Add chili beans drained diced tomatoes tomato sauce chili seasoning beef broth and dry elbow pasta straight to the pan. Stir everything together well to ensure seasonings dissolve and pasta is evenly distributed. This is important for even cooking.
Simmer the Pasta:
Bring the mixture up to a gentle simmer. Lower heat to maintain that simmer as the pasta cooks uncovered. Stir every few minutes to keep anything from sticking to the bottom. After ten to fifteen minutes the pasta should be just tender and most liquid absorbed. If it looks too dry add a splash more broth.
Add the Cheese:
Once pasta is al dente turn off the heat. Stir in all the shredded cheddar until melted and completely incorporated. The cheese should make everything luxuriously creamy with no dry patches.
Serve and Enjoy:
Spoon into bowls straight from the pot and garnish with extra cheese or a few green onions if desired. Enjoy immediately while cheesy and hot.

I have to say the cheddar cheese is my favorite part. Its creamy melt makes every bite taste like your favorite childhood comfort food and instantly upgrades the humble chili mac into something special. My kids take turns adding their own toppings which always leads to a lively dinner table full of laughs.

Storage Tips

Leftover chili mac stores beautifully in an airtight container in the refrigerator for up to three days. If your pasta looks a tad dry after refrigeration just stir in a splash of beef broth or water when reheating to revive its creamy texture. For the freezer portion out cooled chili mac and freeze up to two months then thaw in the fridge overnight before reheating.

Ingredient Substitutions

You can easily substitute ground turkey or sausage for the beef if that is what you have. Shell pasta or rotini are perfect stand ins for elbows. For a vegetarian spin swap in plant based ground crumbles and veggie broth. If you cannot find chili starter any canned chili beans will add the right flavor and heartiness.

Serving Suggestions

I love serving this chili mac with a simple green salad or even with crunchy tortilla chips for scooping. It is also perfect for potlucks or game days served straight from the pot sprinkled with a little extra cheese and fresh chopped cilantro.

Chili Mac Origins

Chili mac is an American mashup born out of the desire to stretch chili with pasta for extra comfort and heartiness. It became a staple in school cafeterias and home kitchens for its budget friendly ingredients and the fun of combining two favorite dishes. It is classic Midwest comfort food at its best.
