Ingredients
The Beef Patties:
-
2 lbs Ground Beef (90% lean recommended)
-
½ cup Panko breadcrumbs
-
1 Large egg, lightly beaten
-
1 tbsp Worcestershire sauce
-
1 tsp Garlic powder
-
1 tsp Onion powder
-
½ tsp Black pepper
-
½ tsp Salt
The Gravy & Veggies:
-
2 cups Beef broth (low sodium)
-
1 packet (1 oz) Brown gravy mix or Onion soup mix
-
1 tbsp Ketchup
-
1 tsp Dijon mustard
-
2 cups Sliced mushrooms (cremini or white button)
-
1 Large yellow onion, thinly sliced
-
2 tbsp Cornstarch + 2 tbsp Water (for thickening slurry)
Instructions
-
Form the Patties: In a large bowl, combine the ground beef, breadcrumbs, egg, Worcestershire sauce, and spices. Mix gently—don’t overwork the meat. Shape into 6 oval patties.
-
The Sear (Optional but Recommended): Heat a skillet over medium-high heat. Brown the patties for 2 minutes per side. They don’t need to be cooked through; this just adds color and locks in flavor.
-
Layer the Slow Cooker: Place the sliced onions and mushrooms at the bottom of the crockpot. Arrange the beef patties on top of the vegetables.
-
Mix the Sauce: In a small bowl, whisk together the beef broth, gravy mix, ketchup, and mustard. Pour the mixture over the patties.
-
Slow Cook: Cover and cook on Low for 4 to 5 hours or High for 2 to 3 hours.
-
Thicken the Gravy: 30 minutes before serving, whisk the cornstarch and water to create a slurry. Stir it gently into the liquid around the steaks. Cover and finish cooking until the sauce is glossy and thick.
Notes & Pro-Tips
-
Lean Beef is Key: Using 90% or 93% lean beef prevents the gravy from becoming overly greasy. If you use 80/20, definitely sear and drain the fat before putting them in the slow cooker.
-
Don’t Overmix: Over-handling the meat makes the patties tough. Mix until just combined.
-
Flavor Boost: Add a splash of red wine to the gravy mixture for a deeper, more sophisticated flavor profile.

Q&A
Q: Can I use frozen patties?A: I wouldn’t recommend it for this specific recipe. The texture of pre-made frozen patties is often too dense. Freshly made patties allow the gravy to penetrate the meat, making it much more tender.
Q: What should I serve this with?A: You can’t go wrong with garlic mashed potatoes or egg noodles to soak up that extra gravy. A side of steamed green beans or roasted carrots balances the richness perfectly.
Q: Can I make this gluten-free?A: Yes! Swap the breadcrumbs for GF crumbs (or crushed GF crackers) and ensure your gravy mix and Worcestershire sauce are certified gluten-free.
