Crockpot recipes are some of my favorites for getting dinner on the table on busy days. With only 20 minutes of active prep time, these crockpot meatballs are quick and easy to make. These Italian-style homemade meatballs are a variation of my go-to meatball recipe, and they cook up so tender and flavorful. The meatballs cook in a simple homemade marinara sauce, or use store-bought sauce to make the prep time even faster.

Why You’ll Love these Crockpot Meatballs

  • The meatballs are extra moist and juicy on the inside with nicely browned outsides. Baking them at a high temperature before adding them to the crockpot is a simple step that makes these the best crockpot meatballs.
  •  Simmering meatballs all day in your slow cooker gives both the meatballs and marinara sauce the best flavor.
  • You can slow cook the meatballs and sauce right away or make them into a freezer meal to cook later.

Ingredients You’ll Need

For the meatballs, you’ll need:

  • Egg: Helps to bind the meatballs together.
  • Garlic: For flavor. You’ll also need fresh garlic for the sauce, so prep it once to save time.
  • Panko Bread Crumbs: Bread crumbs help to bind the meatballs together.
  • Parmesan Cheese: For flavor!
  • Fresh Parsley: Chop it up finely before adding to the meatballs. If you don’t have fresh parsley on hand you can substitute 1 teaspoon of dried parsley or Italian seasoning.
  • Salt and Pepper
  • Ground Beef: I like to use 80% or 85% lean ground beef when making meatballs for the best flavor. You can also use ground turkey.

For the sauce, you’ll need:

  • Onion & Garlic: Creates a flavorful marinara sauce.
  • Crushed Tomatoes, Tomato Sauce and Tomato Paste: These combine to make a rich and hearty tomato sauce with just the right texture.
  • Seasonings: Dried oregano, dried basil, Italian seasoning, bay leaves, salt and pepper give the sauce incredible flavor.

If you’re short on time, you can use two jars of store-bought marinara sauce instead of the homemade sauce ingredients.

How to Make Crockpot Meatballs

  1. To make this crockpot meatballs recipe, start by making the meatballs. Mix together all of the meatball ingredients except for the meat in a bowl. Once you add the meat to the mixture, you want to mix it until it’s just combined. This will ensure that your meatballs turn out soft and tender.
  2. Use your hands to shape the meat mixture into 1 1/2-inch meatballs. Place the meatballs on a lightly oiled baking sheet and bake at 450 degrees F for 10-12 minutes, until cooked through.
  3. While the meatballs bake, add all of the marinara sauce ingredients to the slow cooker and stir to combine.
  4. Gently stir the baked meatballs into the sauce in the crockpot.
  5. Cover and cook on low for 6-8 hours.

Make it a Freezer Meal

These crockpot meatballs are an excellent freezer to crock pot meal. After baking the meatballs, let them cool and then place them in a freezer bag with the marinara sauce ingredients. Store the frozen meatballs and sauce for up to 3 months in the freezer.

Seriously, having these crockpot meatballs in your freezer is the best thing ever when you are craving spaghetti and meatballs mid-week!

More Tips

Do you have to bake meatballs before adding them to your slow cooker?

For best results, bake the meatballs in the oven before adding them to the slow cooker. Baking the meatballs in the oven allows them to brown on the outside and makes for more flavorful meatballs. It also keeps the sauce from being too oily since the meatballs can release some fat as they cook on the baking sheet. The baking step doesn’t add any extra time to the recipe prep since you can mix up the sauce ingredients while the meatballs are in the oven.

If you really want to skip the baking step and add the raw meatballs to the slow cooker, you can and they will cook through. Cook the meatballs and sauce on high (not low) for 3-4 hours, or until cooked through. Be sure to use lean ground beef since all of the extra fat will end up in the sauce.
