Step-by-Step Cooking Instructions
Pre-Cooking Prep
Brown the ground beef in a skillet over medium heat until fully cooked. Drain excess grease. This step helps improve flavor and texture and keeps the chili mac from becoming oily.
Transfer the beef to the slow cooker. Add diced onion, garlic, beans, tomato sauce, diced tomatoes, chili seasoning, salt, pepper, and beef broth. Stir well to combine.
Cooking Method
Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours, until the onions are soft and flavors are well blended.
About 30 minutes before serving, stir in the uncooked macaroni. Make sure the pasta is fully submerged in the liquid. Cover and continue cooking until the pasta is tender.
Doneness or Texture Check
The pasta should be soft but not mushy, and the chili mac should be thick and saucy. If it looks too thick, stir in a splash of broth.
Resting or Final Touches
Turn off the slow cooker and stir in shredded cheese until melted and creamy. Let the chili mac rest for about 5–10 minutes before serving to thicken slightly.
