Q1: How Long to Cook Frozen Meatballs in Crockpot?

Typically, 2–4 hours on high or 4–6 hours on low. Just make sure they reach an internal temp of 165°F to be fully safe and cooked through.

Q2: Will frozen meatballs cook in spaghetti sauce?

Yes! As long as the sauce covers the meatballs and you give them enough time, they’ll cook up tender and flavorful.

Q3: Can I cook them longer than 6 hours?

You can—but I wouldn’t go too far over. They may become too soft or dry. After they’re cooked, switch the crockpot to “Warm.”

Q4: How long can cooked meatballs stay in the crockpot?

They’re safe on “Warm” for up to 3 hours. After that, transfer leftovers to the fridge.

Q5: Is it safe to slow cook frozen meatballs directly?

Yes, if the meatballs are fully cooked when frozen and heated to 165°F in the crockpot, it’s completely safe. For low-carb eaters, this guide to keto-friendly slow cooker meals is packed with flavor and convenience.
