How To Make Loaded Hamburger Steak Casserole
Bring a pot of water to a boil and cook the diced potatoes until they are fork-tender. While the potatoes are boiling, heat olive oil in a large skillet over medium-high heat. Add the chopped onions and mushrooms, cooking for 2-3 minutes. Then, add the ground beef and cook until no pink remains. Season with seasoned salt and drain any excess fat. Set the meat mixture aside.
In the same large skillet over low heat, melt 6 tablespoons of butter. Once melted, sprinkle in the flour and stir constantly for 2-3 minutes. Gradually pour in the beef broth and the packet of dry onion soup mix, whisking everything together. Bring the mixture to a simmer and stir occasionally until it reaches a thick gravy consistency. Set some of the rich gravy aside for later, then add the ground beef mixture back into the skillet. Stir to combine and transfer the hearty ground beef mixture into a 9×13 baking dish.
Once the potatoes are fork-tender, drain the water and transfer the potatoes into a mixing bowl. Add in butter and let it melt. Pour in milk and season with salt and black pepper to taste. Mash the potatoes until smooth using a potato masher or an electric hand mixer. Spread the mashed potatoes over the meat mixture in the casserole dish and smooth the top.
Finish by topping the casserole with the thick gravy you reserved. Serve and enjoy this delicious hamburger steak skillet casserole!
Tip and Tricks for Ground Beef Casserole
- Use Lean Ground Beef: Opt for lean ground beef to avoid too much grease in your casserole. You can also use ground turkey for an even lighter version but the taste will vary.
- For Extra Creaminess: Add a spoonful of sour cream to the mashed potatoes for an even creamier texture.
- Veggie Variations: Add bell peppers or green peppers for an extra burst of color and flavor.
- Thicker Gravy: For a thicker gravy, whisk in a bit more flour with the beef drippings.
How To Store Leftovers
Refrigerate: To store leftovers, let the casserole cool completely. Transfer to an airtight container or cover the casserole dish with plastic wrap. Store in the fridge for up to 3 days.
Freeze: For longer storage, freeze the casserole in individual portions using plastic wrap and an airtight container.
FAQ
- What is the best way to thicken the gravy? The best way to achieve a thick gravy is by whisking purpose flour into the melted butter and letting it cook for 2-3 minutes to form a roux. Slowly add in beef broth and the dry onion soup mix, stirring constantly until it thickens. If you prefer a thicker consistency, you can add a little more flour.
- Can I make this ahead of time? Yes! Assemble everything in the casserole dish and cover it with plastic wrap or foil. Store in the fridge for up to 24 hours before baking, or freeze for up to 3 months for an easy ahead meal. When you’re ready to bake, let it thaw in the fridge overnight, then bake as directed.
- What can I serve with this casserole? This loaded hamburger steak casserole pairs perfectly with a variety of sides, such as green beans, lima beans, or a fresh salad.
- Can I make this recipe without flour? If you want to skip the flour, you can thicken the gravy with cornstarch. Simply mix a tablespoon of cornstarch with cold water and whisk it into the beef broth to achieve a similar thick consistency.
- Can I add cheese to this casserole? Definitely! You can mix shredded cheddar cheese into the mashed potatoes or sprinkle a layer of cheddar on top before baking.
