Equipment
Method
- In a large bowl, combine the ground beef, chopped onion, egg, bread crumbs, Worcestershire sauce, garlic powder, onion powder, salt, and pepper.
- Mix everything together gently with your hands until just combined. Be careful not to overmix.
- Divide the mixture into 6-8 equal portions and shape them into oval patties, about 1/2 inch thick.
- Heat a large skillet over medium-high heat.
- Add the hamburger steaks to the skillet and cook for about 3-4 minutes per side, or until browned. They don't need to be cooked all the way through at this point.
- Remove the steaks from the skillet and set aside.
- In a medium bowl, whisk together the cream of mushroom soup, milk (or beef broth), and Dijon mustard (if using).
- Preheat your oven to 350°F (175°C).
- Grease a 9x13 inch baking dish.
- Pour a thin layer of the creamy sauce into the bottom of the dish.
- Arrange the browned hamburger steaks over the sauce.
- Pour the remaining sauce evenly over the steaks.
- Sprinkle the shredded cheese evenly over the top.
- Bake in the preheated oven for 25-30 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
- If desired, sprinkle with crispy fried onions during the last few minutes of baking.
- Remove the casserole from the oven and let it rest for 5-10 minutes before serving.
- Serve hot and enjoy!
Notes
Don't overmix the meat. Brown, don't cook the steaks completely in the skillet. Customize the cheese with your favorites. Add a pinch of red pepper flakes for a kick. Sautéed mushrooms and onions are a great addition, or other veggies like bell peppers, zucchini, or carrots. You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Serve with mashed potatoes, green beans, corn, or a simple salad. For variations, try Mexican-inspired, Italian-inspired, or a healthier version using lean ground beef or ground turkey and Greek yogurt.
