Ingredients & Prep

This is a beef-and-pasta slow cooker recipe, so timing is key.

Main Ingredients Prep

• Ground beef – Lean works best to avoid excess grease

• Elbow macaroni – Added later so it doesn’t overcook

• Onion – Diced for flavor

• Shredded cheese – Cheddar or a blend melts best

Seasonings, Sauces, or Flavor Base

• Chili seasoning – Store-bought or homemade

• Tomato sauce – Forms the chili base

• Diced tomatoes – Adds texture

• Garlic – Freshly minced for depth

Pantry Staples

• Beef broth

• Olive oil

• Salt and black pepper

• Optional: kidney beans or black beans

Step-by-Step Cooking Instructions

Pre-Cooking Prep

1. Brown ground beef in a skillet over medium heat until fully cooked.

2. Drain excess grease to prevent a greasy final dish.

3. Lightly grease the slow cooker insert.

Cooking Method

1. Add cooked beef, onion, garlic, chili seasoning, tomato sauce, diced tomatoes, beans (if using), and beef broth to the slow cooker.

2. Stir well to combine.

3. Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours.

4. During the last 30–40 minutes, stir in uncooked elbow macaroni.

5. Continue cooking until pasta is tender.

6. Stir in shredded cheese until melted and creamy.

Doneness or Texture Check

The pasta should be tender but not mushy, and the chili mac should be thick, cheesy, and well combined.

Resting or Final Touches

Turn off the slow cooker and let the chili mac rest for 10 minutes before serving. This helps everything thicken slightly.
