Method
- In a large mixing bowl, combine ground beef, breadcrumbs, beaten egg, diced onion, minced garlic, Worcestershire sauce, salt, pepper, and thyme. Gently mix and shape into 6-8 oval patties, about 1/2 inch thick.
- In a small bowl, whisk together onion soup mix, flour, and tomato paste. Gradually add beef broth and soy sauce, whisking until smooth.
- Place sliced onions and mushrooms in the bottom of the slow cooker. Arrange beef patties over the vegetables, then pour the gravy mixture evenly over everything.
- Cover and cook on low for 4-6 hours or high for 2-3 hours, until patties reach an internal temperature of 160°F and gravy is thickened.
- Taste and adjust seasoning with salt, pepper, or Worcestershire sauce if needed. Let rest for 5 minutes before serving.
Notes
Gently mix patties to avoid toughness. Avoid opening the slow cooker lid frequently to maintain consistent cooking. Store leftovers in the refrigerator for up to 4 days or freeze for up to 3 months, reheating gently on the stovetop or in the microwave with a splash of broth.
