🛒 Ingredients

For the Steaks:

• 1½ lb ground beef
• 1 large egg
• ½ cup breadcrumbs
• 2 tbsp milk
• 1 tbsp Worcestershire sauce
• 1 tsp garlic powder
• 1 tsp onion powder
• ½ tsp salt
• ½ tsp black pepper

For the Gravy:

• 1 medium onion, sliced
• 1 green bell pepper, sliced
• 1 red bell pepper, sliced
• 8 oz mushrooms, sliced
• 2 cups beef broth
• 1 tbsp Worcestershire sauce
• 1 tbsp tomato paste
• 1 tsp Dijon mustard
• 1 tsp garlic powder
• ½ tsp black pepper
• 2 tbsp cornstarch + 3 tbsp cold water, optional for thickening
• 1 tbsp butter or olive oil

👩‍🍳 Instructions

1. Make the patties: In a large bowl, combine ground beef, egg, breadcrumbs, milk, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix gently until combined. Shape into 6 oval patties.
2. Brown the steaks: Heat butter or olive oil in a skillet over medium-high heat. Brown the patties for about 2–3 minutes per side. They don’t need to be fully cooked.
3. Prepare the slow cooker: Place sliced onions, bell peppers, and mushrooms in the bottom of the slow cooker.
4. Add the steaks: Arrange the browned beef patties over the vegetables.
5. Make the gravy: Whisk together beef broth, Worcestershire sauce, tomato paste, Dijon mustard, garlic powder, and black pepper. Pour over the steaks and vegetables.
6. Slow cook: Cover and cook on LOW for 5–6 hours or HIGH for 3–4 hours, until the beef is tender and cooked through.
7. Thicken the gravy: During the final 20–30 minutes, mix cornstarch with cold water. Stir the slurry into the gravy and allow it to thicken.
8. Serve: Spoon the rich gravy, peppers, onions, and mushrooms over the Salisbury steaks. Serve immediately.

💡 Pro Tips

• Browning the patties first adds extra flavor and helps them hold their shape.
• Don’t overcrowd the skillet when browning.
• For an extra-rich gravy, add a splash of heavy cream during the final 15 minutes.
• Serve over mashed potatoes, cauliflower mash, rice, or egg noodles.
• For a lower-carb version, replace the breadcrumbs with crushed pork rinds and serve over cauliflower mash.
