Salisbury Steak Casserole

Ingredients (serves 4–6)

For the steaks:

• 1 lb ground beef (85% lean)

• ½ cup almond flour or crushed pork rinds (for low-carb) or regular breadcrumbs

• 1 egg

• 1 small onion, finely chopped

• 1 tsp garlic powder

• 1 tsp Worcestershire sauce

• Salt and pepper, to taste

For the gravy/casserole:

• 2 cups mushrooms, sliced (optional but classic) 🍄

• 1 cup beef broth

• 1 tbsp Dijon mustard

• 1 tsp Worcestershire sauce

• 1 tsp xanthan gum (for low-carb) or 2 tbsp flour

• 2 tbsp butter or oil

Instructions

1. Preheat oven to 375°F (190°C).

2. Make the steak patties

   • In a bowl, mix ground beef, egg, almond flour/breadcrumbs, onion, garlic powder, Worcestershire, salt, and pepper.

   • Form into 4–6 oval patties.

3. Brown the patties

   • Heat butter or oil in a skillet over medium heat.

   • Brown the patties 2–3 minutes per side (they will finish cooking in the oven). Remove patties and set aside.

4. Make the gravy

   • In the same skillet, sauté mushrooms until soft.

   • Add beef broth, Dijon mustard, Worcestershire, and xanthan gum/flour.

   • Stir and simmer until slightly thickened.

5. Assemble the casserole

   • Place patties in a baking dish.

   • Pour the gravy and mushrooms over the top.

6. Bake

   • Bake uncovered for 20–25 minutes until patties are cooked through and gravy is bubbly.

7. Serve

   • Perfect over mashed cauliflower (low-carb) or mashed potatoes.

Tips

• Use lean ground beef to reduce grease.

• For extra flavor, add ½ tsp smoked paprika or fresh herbs to the patties.

• Leftovers reheat well and taste even better the next day.

If you want, I can also make a simpler 1-pan skillet version that skips the oven entirely and takes only 20 minutes. That one’s great for busy nights.
