Set It & Forget It: Frozen Meatballs Crockpot Recipe with Rich Marinara Sauce

Why Frozen Meatballs in the Crockpot Are a Game-Changer

Let’s be real—life is busy. Some nights you just don’t have the time (or energy) to roll fresh meatballs by hand. That’s where frozen meatballs step in as a lifesaver. Combined with marinara sauce in a slow cooker, you get a dish that tastes like it simmered all day without the fuss. Here’s why I love this recipe:

  • Set It & Forget It: The slow cooker handles everything while you go about your day.
  • Versatility: Great for dinners, potluck appetizers, or even sliders for BBQ nights.
  • Savory Comfort: Meatballs soak up the marinara, creating a rich, flavorful dish.
  • Simple & Healthy: With a few smart swaps (like turkey meatballs or low-sodium sauce), you can make it lighter.

Ingredients You’ll Need

Here’s the exact ingredient list I use when making this dish. The measurements are perfect for serving 6–8 people.

  • 2 lbs frozen meatballs (about 40–45 pieces, beef, turkey, or chicken)
  • 48 oz (two 24 oz jars) marinara sauce
  • 1 medium onion, finely chopped (about 1 cup)
  • 3 cloves garlic, minced
  • 1 tbsp Italian seasoning
  • 1 tsp red pepper flakes (optional, for a spicy kick)
  • 1 tbsp olive oil
  • 1/2 cup grated Parmesan cheese (for serving)
  • Fresh basil leaves (optional garnish)

Optional add-ins: For a BBQ twist, swap one jar of marinara with 1 1/2 cups of your favorite BBQ sauce. For a healthy option, choose lean turkey meatballs and a no-sugar-added marinara.


How to Cook Frozen Meatballs in the Crockpot with Marinara Sauce

  1. In your slow cooker, drizzle 1 tbsp olive oil and add the chopped onion and garlic to the bottom.
  2. Place the 2 lbs of frozen meatballs directly into the slow cooker (no need to thaw!).
  3. Pour the 48 oz marinara sauce over the meatballs.
  4. Sprinkle in 1 tbsp Italian seasoning and 1 tsp red pepper flakes (if using).
  5. Stir gently so everything is coated evenly.
  6. Cover with the lid and cook:
    • Low: 6–8 hours
    • High: 3–4 hours
  7. Once cooked, top with fresh basil and Parmesan before serving.

That’s it—so simple, so savory, and absolutely foolproof!
