How to Make Slow Cooker Italian Meatballs
Step 1: Prepare the Breadcrumb Mixture
In a small bowl, combine:
- Breadcrumbs
- Milk
Allow the mixture to sit for:
5–10 minutes
until the breadcrumbs absorb the milk.
This creates softer, more tender meatballs.
Step 2: Make the Meatball Mixture
In a large bowl, combine:
- Ground beef
- Ground pork
- Soaked breadcrumbs
- Eggs
- Parmesan cheese
- Garlic
- Parsley
- Basil
- Worcestershire sauce
Add:
- Italian seasoning
- Salt
- Black pepper
- Red pepper flakes
Mix gently until combined.
Avoid overmixing because it can make the meatballs tough.
Step 3: Shape the Meatballs
Using clean hands or a scoop, form the mixture into meatballs.
Make them about:
1½–2 inches wide
You should get approximately:
24–30 meatballs
Place them on a tray while preparing the sauce.
Step 4: Prepare the Tomato Sauce
In the slow cooker, add:
- Crushed tomatoes
- Diced tomatoes
- Onion
- Garlic
- Tomato paste
- Olive oil
- Balsamic vinegar
- Oregano
- Italian seasoning
- Black pepper
Stir everything together.
This creates the flavorful base where the meatballs will slowly cook.
Step 5: Add the Meatballs
Carefully place the raw meatballs into the sauce.
Arrange them in a single layer if possible.
Do not overcrowd them too much because they need space to cook evenly.
Spoon some sauce over the top.
Step 6: Slow Cook the Meatballs
Cover the slow cooker.
Cook on:
Low: 5–6 hours
or
High: 3–4 hours
The meatballs are ready when they are cooked through and tender.
Avoid stirring too much during cooking because the meatballs can break apart.
Step 7: Finish the Sauce
Before serving, gently stir the sauce around the meatballs.
Add fresh basil leaves.
Taste and adjust seasoning if needed.
For a richer sauce, allow the meatballs to sit on the warm setting for:
15–20 minutes
before serving.
