Equipment

  • Slow Cooker

Ingredients

  • 16 oz frozen meatballs beef or turkey
  • 8 oz sliced mushrooms
  • ½ cup chopped yellow onion
  • 2 cloves garlic minced
  • 2 tablespoons butter
  • 2 tablespoons flour
  • 2 teaspoons soy sauce
  • 1 teaspoon dijon mustard
  • 1 ½ cups beef broth

Instructions

  • Add meatballs, mushrooms, onion, garlic, and butter to slow cooker.
  • Whisk flour with 4 tablespoons of water until smooth.
  • Mix remaining ingredients with flour mixture, then pour over meatballs in the slow cooker.
  • Cover and cook on high for 2-3 hours or low for 4-6 hours. (Sauce will thicken upon cooking, and meatballs should reach at least 165 ℉.)
  • Serve over mashed potatoes, noodles, or mashed cauliflower for a lower-carb option.

Notes

  • Store leftovers in an airtight container in the fridge for 3-4 days.
  • Reheat gently on the stovetop with a splash of broth, or in the microwave, stirring between intervals to heat evenly.
  • Frozen meatballs do not need to be thawed prior to cooking.
  • Thicken gravy with additional broth or a flour-water slurry and cook uncovered for 15-30 more minutes. To thin the gravy, add more broth or water.
