👩🍳 Step-by-Step Instructions
Step 1: Mix and Shape the Patties
In a large bowl, combine the ground beef, breadcrumbs, egg, milk, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Use your hands to gently mix just until combined (do not overwork the meat or the patties will become dense). Shape the mixture into 4 to 6 oval-shaped patties, roughly ¾-inch thick.
Step 2: Sear the Beef
Heat 1 tablespoon of olive oil or butter in a large skillet over medium-high heat. Add the patties and sear for 3 to 4 minutes per side until a beautiful golden-brown crust forms. They do not need to be cooked completely through at this stage, as they will finish cooking in the oven. Transfer the patties to a plate and set aside.
Step 3: Cook the Mushrooms and Onions
Turn the skillet heat down to medium and melt the 2 tablespoons of butter. Add the sliced onions and mushrooms to the pan, scraping up all those delicious browned beef bits from the bottom. Sauté for about 6 to 8 minutes until the mushrooms are tender and the onions are soft and caramelized.
Step 4: Build the Gravy
Sprinkle the flour over the cooked mushrooms and onions, stirring constantly for 1 to 2 minutes to cook out the raw flour taste. Slowly pour in the beef broth a little at a time, whisking continuously to prevent lumps. Stir in the Worcestershire sauce and Dijon mustard. Bring the mixture to a gentle simmer and let it cook for 3 to 5 minutes until it thickens into a rich, glossy gravy. Season with salt and pepper to taste.
Step 5: Assemble and Bake
Preheat your oven to 375°F (190°C). Arrange your seared beef patties in a 9×13-inch baking casserole dish. Pour the rich mushroom and onion gravy generously all over and around the patties. Top the dish with an even, heavy blanket of shredded cheese, exactly like the golden layering shown in image_28ce65.jpg. Bake uncovered for 15 to 20 minutes until the beef is fully cooked and the cheese is melted, bubbling, and beautifully browned around the edges.
Step 6: Garnish and Serve
Remove from the oven and let it sit for 5 minutes. Scatter your freshly chopped parsley across the bubbling cheese crown to match the gorgeous presentation in image_28ce65.jpg. Serve hot over a bed of creamy mashed potatoes, egg noodles, or white rice to soak up all that incredible gravy.
💡 Quick Variations to Try
- French Onion Style: Double the amount of onions and let them caramelize deeply before making the gravy. Use Swiss or Gruyère cheese over the top for a fantastic French Onion soup twist.
- Spiced Herb Twist: Stir ½ teaspoon of dried thyme or rosemary into the mushroom gravy to give the sauce a wonderful, earthy herbal aroma.
