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
- 1/4 cup butter
- 1 (24 ounce) container refrigerated mashed potatoes (or make your own)
Step 1In a small bowl or measuring cup, whisk the two packets of brown gravy mix with two cups of water. Place the frozen meatballs, carrots, and chopped celery into the slow cooker and pour the cold gravy mixture over them, tossing gently to coat.

Step 2Sprinkle the onion soup mix evenly over the gravy-coated meatballs and vegetables. Cut the butter into small pieces and distribute them across the top.

Step 3Cook on LOW for 3–4 hours. Stir once about halfway through so everything cooks evenly and the flavors blend. Push the carrots down into the sauce to help them soften.

Step 4Just before serving, prepare the mashed potatoes according to package directions or warm your homemade potatoes. Alternatively, add a few baby potatoes to the crockpot at the start with the other vegetables.

This recipe creates a rich, gravy-forward dish that’s perfect over mashed potatoes. The combination of tender meatballs, soft vegetables, and savory gravy delivers classic comfort food flavors that appeal to kids and adults alike.

Notes
- I used a 26-ounce bag of homestyle frozen meatballs (about 55 small meatballs), but the exact amount is flexible. Many brands work well.
- If you prefer, add a few baby potatoes or chopped potatoes to the slow cooker instead of serving over mashed potatoes; they cook in about the same time as the carrots.
- Optional additions include onions, mushrooms, garlic, or a bit of black pepper to taste.
- Serve this pot roast over baked potatoes or rice for a different presentation.
- While sides aren’t necessary, garlic bread or dinner rolls pair nicely.
