Pro Tips for the Best Results
- Mix gently and just until combined; overmixing makes meatballs dense.
- Browning the meatballs first adds flavor and helps them hold their shape, but you can add them raw to the sauce.
- Use a cookie scoop for evenly sized meatballs.
- Always confirm 160°F (71°C) for ground beef before serving.

How to Cook Crockpot Meatballs
New to this dish? Follow along with the detailed guide below — we break down each stage so you get perfect results the very first time.
Mix and roll gently
Combine the meatball ingredients with a light hand, just until they come together — overmixing makes them dense and tough. A cookie scoop gives uniform meatballs that cook evenly.
Brown for best texture (optional)
Searing or baking the meatballs until browned before they go in firms them up and adds flavor, so they hold their shape in the sauce. If you're short on time, you can add them raw and let them cook through in the marinara.
Simmer in sauce
Cook the meatballs gently in the marinara until they reach a safe 160°F (71°C) and have soaked up the sauce. Switch to WARM to hold them for a party, or serve over pasta or in subs.
Storage & Make-Ahead
Refrigerate leftovers in an airtight container for up to 4 days; reheat in the sauce. Cooked meatballs freeze well for up to 3 months.
Serving Suggestions
This crockpot meatballs pairs beautifully with a crisp green salad, crusty bread, or your favorite grain. Add a simple side of roasted vegetables for a complete, satisfying dinner the whole family will enjoy.
Frequently Asked Questions
Do I have to brown the meatballs first?+
No — they'll cook through in the sauce. Browning adds flavor and firmer texture, but raw-to-sauce works and is easier.
Can I use frozen meatballs?+
Yes — add frozen pre-cooked meatballs with the sauce and heat on LOW 3-4 hours until hot throughout.
Can I keep them warm for a party?+
Yes — switch to the WARM setting and they'll hold beautifully for serving.
