How to Make Slow Cooker Italian Meatballs (Step-by-Step)

Don’t worry—this is simple, approachable, and totally doable even on a chaotic day.

1. Mix the Meatballs

In a large bowl, add the 2 ground beef, onion, garlic, parsley, breadcrumbs, eggs, Parmesan, salt, and pepper.
Use your hands to gently mix everything until just combined. Don’t overmix—think soft and tender, not worked too hard.

2. Shape Them Up

Form the mixture into 1- to 2-inch meatballs. You should get about 24 meatballs, give or take.
No need to stress if they’re not perfect. Rustic is charming.

3. Broil for Flavor

Lightly grease a baking sheet and place the meatballs on it.
Broil on high until browned on each side, about 4–5 minutes per side.
This step adds flavor and helps the meatballs hold their shape later. Totally worth it.

4. Into the Slow Cooker

Transfer the browned meatballs to your slow cooker.
Pour the crushed tomatoes and tomato paste over the top, then add the bay leaves, red pepper flakes, and Italian seasoning.

5. Let the Magic Happen

Cover and cook on low for 4 hours.
Once done, taste the sauce and adjust with salt and pepper as needed.

6. Serve & Enjoy

Serve warm with fresh basil or extra Parmesan on top. Pasta, crusty bread, or even a meatball sub—this is your moment.

My Best Tips for Success

Don’t skip the broil: It adds flavor and keeps the meatballs from falling apart.
Too thick? Add a splash of water or broth to loosen the sauce.
Too thin? Leave the lid slightly ajar for the last 20 minutes.
Spice level: Love heat? Add extra red pepper flakes. Prefer mild? You can skip them entirely.

And if your sauce looks extra thick and rich? Congratulations—that’s not a problem. That’s comfort.
