Crock Pot Tomato Sauce
I hope you'll use this recipe as a guide and adjust the seasonings to your family's taste. Because that's what all good home-cooks do. We cook for our family.
You can make this recipe in a crock pot or on top of the stove in a heavy Dutch Oven. I like to use my crock pot because there's no risk of burning the sauce while I'm busy working.

Main Ingredients Needed
Here's a quick overview of the ingredients for this recipe. Find the exact amounts and click the Instacart button to easily add them to your cart – all in the printable recipe card below!
Substitutions and Variations
- Ground turkey or chicken: Swap in lean ground turkey or chicken for a lighter option for the meatballs. Add an extra tablespoon of olive oil or a splash of milk to keep the meatballs moist.
- Bake the meatballs in the oven: Preheat oven to 400°F. Place shaped meatballs on a parchment-lined baking sheet and bake for 18–20 minutes, or until cooked through and lightly browned, then add them to the slow cooker sauce.
- Blend for a Smoother Sauce – If you prefer a smoother texture, blend the plum tomatoes before adding them to the slow cooker. It makes a big difference in consistency.
- Want More Flavor? Add a Parmesan Rind – Adding a small wedge or rind of Parmesan cheese while the sauce cooks adds a deep, savory flavor that brings everything together.

Step-by-Step Directions

Step 1: In a large bowl, combine the ground beef, breadcrumbs, garlic, salt, pepper, parsley, and milk. Mix gently until just combined.
Step 2: Form the mixture into meatballs and refrigerate for 15 minutes. This will help them hold their shape during cooking.
Step 3: Heat a generous amount of oil in a heavy frying pan over medium-high heat. Add the meatballs and brown them evenly on all sides.
Step 4: Remove the browned meatballs from the pan and drain them briefly on paper towels. This will remove excess grease before adding them to your tomato sauce.
How to Flash-Freeze Meatballs for Easy Storage
Don't need all these meatballs for dinner tonight?
- Place the partially cooked meatballs on a baking tray lined with parchment paper.
- Allow them to cool slightly.
- Then place the baking tray in the freezer to flash freeze the meatballs for about 30 minutes.
- Once frozen, wrap them in aluminum foil and store in a freezer-safe plastic container or bag.
Next time you make tomato sauce, add the frozen meatballs straight to the slow cooker—they’ll cook through as the sauce finishes.
Step 5: Add all your tomato sauce ingredients directly to the slow cooker. If using whole tomatoes, gently break them up in the slow cooker using the back of a spoon or a meat chopper. Carefully add the meatballs to the sauce, ensuring they're partially submerged.
Step 6: Cook on low for 4 to 6 hours or until the meatballs are cooked through.
Insider Tips from My Kitchen to Yours
✔️ DO: Sear the meatballs first – browning them before adding to the slow cooker helps them hold their shape and adds extra flavor to the sauce.
❌ DO NOT: Skip draining excess fat after searing; leaving too much grease can make the sauce oily and heavy
Storing, Freezing, Thawing and Reheating Tips
Refrigerator: Store leftover meatballs and sauce in an airtight container in the refrigerator for up to 4 days.
Freezer: You can also freeze the leftover sauce in airtight containers for up to 3 months.
Thawing and Reheating: Thaw frozen meatballs and sauce overnight in the refrigerator, then gently reheat on the stovetop, in the microwave, or in the slow cooker.
Here's how to freeze cooked ground beef or partially cooked meatballs:
- Place the partially cooked meatballs on a baking tray lined with parchment paper.
- Allow them to cool slightly.
- Then place the baking tray in the freezer to flash freeze the meatballs for about 30 minutes.
- Once frozen, wrap them in aluminum foil and store in a freezer-safe plastic container or bag.
