A cozy slow cooker meatball stew with tender meatballs, hearty vegetables, and a rich tomato-beef gravy. Minimal prep and hands-off cooking make it perfect for busy, chilly days.
For best flavor and texture, brown homemade meatballs before adding. Cut potatoes uniformly so they cook evenly. Use low-sodium broth and adjust salt at the end. Do not overfill the slow cooker. To use frozen meatballs, add from frozen and cook on LOW 7–8 hours or HIGH 4–5 hours. For thicker stew, repeat the cornstarch slurry or mash some potatoes. Leftovers keep 4 days refrigerated or 3 months frozen. Variations: add mushrooms, spice with red pepper flakes or chipotle, finish with cream, or try turkey/chicken meatballs. Stovetop option: simmer covered 45–60 minutes, then thicken and add peas.
