Ingredients
Method
Preheat the oven:
- Set your oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish.
Prepare the hamburger steak mixture:
- In a large bowl, combine ground beef, breadcrumbs, egg, salt, and pepper. Mix until just combined.
- Form into oval-shaped patties and arrange them in the baking dish.
Cook the onions:
- In a skillet, melt the butter over medium heat. Add the sliced onions and sauté until softened, about 3–5 minutes.
Prepare the gravy:
- In a bowl, whisk together the cream of mushroom soup, milk, and Worcestershire sauce until smooth.
Assemble the bake:
- Spread the sautéed onions over the hamburger patties.
- Pour the prepared gravy evenly over the top.
Bake:
- Cover the dish with foil and bake for 30 minutes. Remove the foil and bake for an additional 15 minutes, or until the patties are fully cooked and the gravy is bubbling.
Serve:
- Garnish with chopped parsley and serve hot with mashed potatoes or a side of vegetables.
Notes
- For a richer flavor, substitute cream of mushroom soup with homemade gravy.
- Add sliced mushrooms or bell peppers for extra texture and flavor.
- Store leftovers in an airtight container in the fridge for up to 3 days.
