Frozen meatballs are a great shortcut for quick dinners — they store well in the freezer and can be transformed into many different meals. This slow cooker pot roast uses pantry staples and a couple of seasoning packets to create a rich gravy that pairs perfectly with mashed potatoes, rice, or crusty bread.
How To Make A Slow Cooker Pot Roast With Frozen Meatballs

Ingredients
- 1 (26 ounce) bag frozen meatballs
- 2 cups baby carrots
- 5 stalks celery, chopped
- 2 packets brown gravy mix
- 1 packet onion soup mix
- 2 cups water
- ¼ cup butter, sliced into small pieces
- 24 ounces refrigerated mashed potatoes (or make your own)
Step 1. Place the frozen meatballs, baby carrots, and chopped celery into your slow cooker. In a small bowl or measuring cup, whisk together the two packets of brown gravy mix with two cups of water until smooth. Pour the cold gravy mixture over the meatballs and vegetables and gently toss to coat.

Step 2. Sprinkle the packet of onion soup mix evenly over the top. Cut the butter into small pieces and distribute them across the surface so they melt into the gravy as it cooks.

Step 3. Cook on LOW for 3–4 hours. Stir once halfway through cooking to ensure even heat distribution and to incorporate the butter and seasonings. Push the carrots down into the sauce if needed so they soften evenly.

Step 4. About 10 minutes before you’re ready to serve, prepare the refrigerated mashed potatoes according to package directions or warm your homemade mashed potatoes. You can also add a few small potatoes to the slow cooker with the other vegetables if you prefer not to use premade mashed potatoes.

The rich gravy makes this dish especially good served over mashed potatoes, where the sauce soaks into every bite. The combination of tender meatballs, soft carrots, and savory gravy creates a comforting meal that appeals to picky eaters and adults alike.

Notes & Tips
- I used a 26-ounce bag of homestyle frozen meatballs that included about 55 small meatballs, but exact amounts can vary. Feel free to use the brand you prefer.
- If you’d rather not use refrigerated mashed potatoes, add several handfuls of baby potatoes or chopped potatoes to the slow cooker at the start; they should cook in roughly the same time as the carrots.
- Additions like sliced onions, mushrooms, minced garlic, or a pinch of black pepper work well. Adjust seasoning to taste.
- Try serving the pot roast over rice, a baked potato, or with dinner rolls or garlic bread for soaking up extra gravy.
- Leftovers can be cooled, refrigerated, and reheated gently on the stovetop or in the microwave until warmed through.
