Description

Hearty slow cooker meatball casserole brings comfort and flavor from Italy to your dinner table. Savory beef meatballs nestled in rich tomato sauce create a satisfying meal you’ll crave again and again.


Ingredients

Scale
  • 1 bag (24 oz / 680 g) frozen fully cooked meatballs
  • 3 cups marinara sauce
  • 3 cups uncooked pasta (penne or rotini)
  • 2 cups water or low-sodium chicken broth
  • 1 tsp Italian seasoning
  • ½ tsp garlic powder
  • Salt and pepper, to taste
  • 1 ½ cups shredded mozzarella cheese
  • ¼ cup grated Parmesan cheese
  • Fresh parsley or basil, chopped (optional, for garnish)

Instructions

  1. Preparation: Lightly spray the interior of the slow cooker with nonstick cooking spray to prevent adhesion.
  2. Meatball Layer: Arrange meatballs in the slow cooker and pour marinara sauce, ensuring complete coverage and creating a robust flavor foundation.
  3. Seasoning Integration: Incorporate Italian herbs, garlic powder, salt, and pepper throughout the mixture, gently stirring to distribute flavors evenly and enhance overall taste profile.
  4. Pasta Incorporation: Submerge uncooked pasta within the sauce, positioning pieces to guarantee uniform cooking and maximum sauce absorption.
  5. Cooking Progression: Select high temperature setting for 2.5-3 hours or low setting for 5-6 hours, allowing ingredients to meld and pasta to reach optimal tenderness while developing deep, complex flavors.
  6. Cheese Finalization: Generously scatter mozzarella and Parmesan cheese across the surface, creating a luxurious molten blanket that transforms the casserole’s texture and visual appeal.
  7. Serving Presentation: Once cheese becomes golden and bubbling, remove from slow cooker and garnish with fresh herbs, presenting a vibrant, aromatic dish ready for immediate enjoyment.

Notes

  • Prevent Pasta Sticking: Stir pasta gently midway through cooking to avoid clumping and ensure even moisture distribution.
  • Customize Meat Options: Swap traditional beef meatballs with turkey, chicken, or plant-based alternatives for dietary preferences or health considerations.
  • Cheese Melting Technique: Add cheese during the last 30 minutes of cooking to achieve perfect golden-brown melting without burning.
  • Liquid Balance Matters: Adjust marinara sauce quantity if using different pasta types to maintain ideal moisture and prevent dryness.
