Slow Cooker Ground Beef & Shells Casserole

🍲 Description

Slow Cooker Ground Beef & Shells Casserole is a comforting, family-style pasta dish made with tender pasta shells, seasoned ground beef, rich tomato sauce, and melted cheese. It’s designed to cook slowly so flavors deepen and the pasta absorbs the savory sauce, creating a hearty, one-pot meal with minimal effort.

🛒 Ingredients

  • 500–700 g ground beef
  • 1 medium onion (finely chopped)
  • 3 cloves garlic (minced)
  • 2 cups marinara or tomato pasta sauce
  • 1 can (400 g) diced tomatoes
  • 1 tsp salt (adjust to taste)
  • 1 tsp black pepper
  • 1 tsp Italian seasoning
  • 1/2 tsp chili flakes (optional)
  • 2 cups beef broth or water
  • 2 cups medium pasta shells (uncooked)
  • 1 to 1½ cups shredded mozzarella cheese
  • 1/4 cup grated Parmesan cheese
  • Fresh parsley (optional garnish)

👩‍🍳 Instructions

  1. Brown the beef
    In a skillet, cook ground beef with onion until browned. Add garlic and cook 1–2 minutes. Drain excess fat.
  2. Load the slow cooker
    Add beef mixture, tomato sauce, diced tomatoes, seasonings, and broth into the slow cooker. Stir well.
  3. Slow cook
    • Low: 5–6 hours
    • High: 3–4 hours
  4. Add pasta
    Stir in uncooked pasta shells during the last 30–45 minutes of cooking. Ensure they are submerged in liquid.
  5. Add cheese
    Once pasta is tender, mix in mozzarella and Parmesan. Let melt for 5–10 minutes.
  6. Serve
    Garnish with parsley and serve warm.

📝 Notes

  • Do not add pasta too early or it will become mushy.
  • If mixture becomes too thick, add a splash of broth.
  • You can substitute shells with penne or macaroni.

Q3: Can I freeze it?

Yes, but freeze before adding pasta for best texture. Cook pasta fresh when serving.

Bell peppers, mushrooms, spinach, or zucchini work very well.
