Frozen Meatballs in Slow Cooker: How I Fell in Love with This Easy Comfort Food

Why This Recipe Matters to Me

Back on the farms of Texas where I grew up, hearty, no-fuss meals were our everyday comfort. These days, living in New York with three energetic kids, I still look for that same warmth—but I need it fast. I’ll never forget one snowy afternoon when I had zero time and tossed a bag of meatballs into the Crockpot with some sauce. By dinner, the house smelled incredible, the kids were smiling, and I felt like I’d pulled off something magical without breaking a sweat.

That’s when I realized just how much I value recipes that work hard for you. Simple, hands-off dinners like this one give me space to focus on what matters. Whether it’s soccer practice chaos or a mountain of laundry, knowing dinner is already taken care of brings such relief.

Using meatballs from the freezer in a slow cooker lets me serve up something delicious without the stress. It’s a meal that doesn’t just feed the belly—it brings everyone to the table, together. And that’s why it’s a staple in my busy home.

Where It Fits in My Weekly Routine

This recipe isn’t just a once-in-a-while dinner—it’s a reliable, go-to solution. I often pair it with pasta or serve it as subs on hoagie rolls for a satisfying twist. If you’re like me and value meals that are practical but still packed with flavor, frozen meatballs in the crockpot will quickly become your favorite.

If you’re new here, you’ll also enjoy recipes like Corned Beef Slow Cooker Guinness and my family-favorite Corned Beef Brisket Slow Cooker, which also use simple ingredients and big flavor.

Frozen Meatballs in Slow Cooker: Cooking Time & Methods

How Long to Cook Frozen Meatballs in Slow Cooker

Frozen meatballs in slow cooker recipes are a game-changer when you need dinner to cook itself. The question I get most is, how long to cook frozen meatballs in slow cooker? Here’s the deal: if your meatballs are fully cooked when frozen (most store-bought ones are), you only need to heat them through and let them soak up the sauce. Set your slow cooker on low for 4–6 hours or on high for 2–3 hours.

If you’re adding them to a sauce—like marinara, BBQ, or Swedish-style gravy—this time allows the meatballs to absorb all the flavor while staying juicy and tender. Always check the center to make sure they’re heated through before serving.

For a hands-off family meal, this timing is perfect. You can put everything in the Crockpot mid-morning and come home to dinner ready to go. This recipe pairs beautifully with hearty side dishes or even a fresh green salad.

Tips for Even Cooking and Safety

Make sure to place the frozen meatballs at the bottom of the slow cooker so they heat quickly and evenly. If you’re cooking from frozen, don’t skip the sauce. It acts as a buffer and ensures the meatballs cook safely and thoroughly. Never pile in dry meatballs alone—you want moisture in the pot.

Wondering if you can skip thawing them? Absolutely. One of the best things about frozen meatballs in the crockpot is that no thawing is required. Just toss them in with your favorite sauce, and you’re good to go.

Storage and Reheating Tips

Leftovers? Yes, please. Frozen meatballs in the crockpot reheat beautifully and make meal prep a breeze.

Here’s how to store them:

  • Fridge: Let leftovers cool, then store in an airtight container for up to 4 days.
  • Freezer: Store cooked meatballs and sauce in freezer-safe containers for up to 2 months. Thaw overnight in the fridge.

To reheat, warm gently on the stove-top or in the microwave with a splash of sauce or water to loosen it up. You can even toss them back into the slow cooker on low to reheat in bulk.

FAQs

Can I put frozen meatballs in a slow cooker?

Yes, you absolutely can. Frozen meatballs go straight from the freezer into the slow cooker—no thawing required. Just make sure they’re fully cooked (as most store-bought ones are), add sauce, and cook on low for 4–6 hours or high for 2–3 hours until heated through.

How long does it take to cook fully cooked frozen meatballs?

In a slow cooker, fully cooked frozen meatballs typically take 4–6 hours on low or 2–3 hours on high. The time ensures they heat all the way through and absorb the sauce’s flavor without overcooking.

How long does frozen meat take to cook in a slow cooker?

Frozen meats like roasts or chicken breasts can take 6–9 hours on low, depending on size and thickness. For frozen meatballs, since they’re usually precooked and smaller, the cook time is shorter—just 2–6 hours depending on your heat setting.

How long does it take to cook meatballs in a slow cooker?

If you’re using raw meatballs, they’ll need about 6–8 hours on low or 4–5 hours on high. For frozen precooked meatballs, stick to 2–3 hours on high or 4–6 hours on low.
