Ingredients You’ll Need

4 cups passata: This Italian tomato purée base lends a fresh, rich flavor that complements the meatballs perfectly. If unavailable, you can substitute with crushed tomatoes.
400g chopped tomatoes (canned): Opt for good-quality to ensure amazing flavor in the sauce; fire-roasted varieties add a smoky twist.
2 tablespoons tomato paste: This thickens the sauce and intensifies the tomato flavor.
1 teaspoon dried oregano: A must in Italian cooking, oregano adds a fragrant, earthy note.
2 cloves garlic, crushed: Fresh garlic elevates the dish with its aromatic punch; feel free to use garlic powder in a pinch.
1 tablespoon maple syrup: This little sweetener balances out the acidity of the tomatoes beautifully.
1 beef stock cube: It enhances the meatiness of the dish; vegetable stock works well for a lighter flavor.
Salt and black pepper to season: Essential for balancing all the flavors.
1 pound extra-lean ground beef: The star of our dish, it’s hearty yet low in calories. Ground turkey or chicken could work as a substitute for a leaner option.
1 small onion, grated: This adds moisture and flavor. You can use shallots if you want a milder taste.
1 teaspoon garlic powder: Extra flavor here; another option is to use onion powder for a different depth.
1 tablespoon dried parsley: A touch of green for freshness; fresh parsley could be used instead—just double the amount.
3 tablespoons red pesto: This great ingredient packs a punch; feel free to experiment with other pestos for a different flavor profile.
30g grated Parmesan: For that perfect cheesy finish. Nutritional yeast serves as a dairy-free option.
30g dried breadcrumbs: These help bind the meatballs; gluten-free breadcrumbs work as an alternative.
1 egg: Acts as a binding agent in the meatball mixture.

How to Make Slow Cooker Pesto Beef Meatballs

Prepare the Sauce: In your slow cooker, add 4 cups passata, 400g of chopped tomatoes, 2 tablespoons tomato paste, 1 teaspoon dried oregano, 2 crushed cloves of garlic, and 1 tablespoon maple syrup. Crumble in the beef stock cube, then season with salt and black pepper. Stir to combine everything well; the aroma alone will have you dreaming about what’s to come!
Mix the Meatball Ingredients: In a mixing bowl, combine 1 pound of extra-lean ground beef, 1 small grated onion, 1 teaspoon garlic powder, 1 tablespoon dried parsley, 3 tablespoons red pesto, 30g grated Parmesan, 30g dried breadcrumbs, and 1 egg. Mix gently until just combined, being careful not to overwork the meat; that’s the secret to juicy meatballs.
Form Meatballs: With clean hands, shape the mixture into approximately 20 meatballs, aiming for a bite-sized portion. It’s fun, a little messy, and completely worth it!
Cook the Meatballs: Gently place the meatballs into the prepared sauce, ensuring you spoon some sauce over each one to ensure they’re well coated. Cover your slow cooker and choose to cook on low for 8 hours or high for 4 hours; either way, you’ll come home to a heavenly smell wafting through the air.
Taste & Adjust: Once cooked, give the sauce a little taste, and add more salt or pepper if needed. The flavors can intensify during cooking, making this step essential for tailored flavor.
Serve & Enjoy: Pair the meatballs with your choice of sides – spaghetti, over rice, or in a soft roll. Each serving remains juicy and flavorful, ensuring everyone at your table will be asking for the recipe.

Storing & Reheating

Store your Slow Cooker Pesto Beef Meatballs in an airtight container once cooled, and keep them in the refrigerator for up to 4 days. You can also freeze them for an impressive 3 months. To reheat, simply pop them in the microwave for about 2-3 minutes, or simmer on the stove for a few minutes until heated through. Note that the texture may slightly change after freezing, but a good stir with a splash of water can refresh the sauce beautifully.

Chef’s Helpful Tips

Aim for a gentle hand when mixing the meatball mixture; overworking can lead to tough meatballs.
Use room temperature ingredients for a cohesive mix; meatballs come together best this way.
If the meatball mixture seems too wet, add more breadcrumbs gradually until the right consistency is achieved.
Consider adding finely chopped vegetables, like spinach or bell peppers, for an extra nutrition boost.
Feel free to swap the protein for ground turkey or chicken; just adjust the cooking time accordingly.
