Ingredients

For the beef patties:

• 1 1/2 pounds ground beef
• 1/3 cup breadcrumbs
• 1 large egg
• 2 tablespoons milk
• 1 teaspoon Worcestershire sauce
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1/2 teaspoon salt
• 1/2 teaspoon black pepper
• 2 tablespoons olive oil

For the mushroom gravy:

• 2 tablespoons butter
• 1 small onion, finely chopped
• 3 cloves garlic, minced
• 8 ounces mushrooms, sliced
• 2 tablespoons all-purpose flour
• 2 cups beef broth
• 1/2 cup heavy cream
• 1 teaspoon Dijon mustard
• Salt and pepper to taste
• Fresh parsley, chopped (for garnish)

Instructions

Start by mixing the ground beef in a large bowl with breadcrumbs, egg, milk, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Combine gently — just enough to bring everything together without overworking the meat.

Shape the mixture into 4 to 6 thick oval patties. They don’t need to be perfect; rustic shapes actually make it feel more homemade.

Heat olive oil in a large skillet over medium-high heat. Sear the patties for about 2 to 3 minutes per side, just until they’re nicely browned on the outside. They will finish cooking in the oven, so don’t worry about the inside yet.

Place the browned patties into a baking dish.

In the same skillet, melt the butter and add the chopped onions. Cook until soft and slightly golden, letting them release their sweetness. Add the garlic and mushrooms, and sauté until the mushrooms are browned and fragrant.

Sprinkle in the flour and stir well for about a minute. This helps create a smooth, thick gravy.

Slowly whisk in the beef broth, making sure everything stays smooth and lump-free. Then add the heavy cream and Dijon mustard. Stir gently as the sauce begins to thicken into a rich, silky gravy. Season with salt and pepper to taste.

Pour the mushroom gravy over the beef patties in the baking dish, covering them generously.

Bake in a preheated oven at 375°F (190°C) for 25–30 minutes, until the sauce is bubbling and the patties are fully cooked through.

Presentation

Once out of the oven, sprinkle fresh chopped parsley over the top while everything is still steaming hot. That little touch of green makes the dish look fresh and inviting.

Serve it over a generous scoop of mashed potatoes so the creamy mushroom gravy can soak right in. It also pairs beautifully with rice or a piece of crusty bread for dipping into the sauce.

For a cozy dinner table feel, serve it in shallow bowls so the gravy gathers around the steak — warm, rustic, and comforting.
