How to Make Hamburger Supreme Casserole
Now, let’s get cooking! These steps are super straightforward and perfect for anyone, whether you’re a kitchen newbie or a seasoned pro.
Prep It Up: Start by gathering all your ingredients. Trust me, meal prep makes things a million times easier!
Cook the Beef: In a large pot or skillet, heat that tablespoon of olive oil over medium heat. Toss in the diced onions and cook until they’re translucent (about 3-4 minutes). Then, add the ground beef and a couple pinches of salt and pepper. Cook it until it’s browned, breaking it apart as it cooks; this takes about 5-7 minutes.
Garlic Time: Once the beef is cooked, stir in the minced garlic. You’ll want to cook it until fragrant, maybe a minute, so you get all that yummy garlic goodness!
Mix in The Veggies: Now it’s time to add in the frozen mixed vegetables. Stir to combine and cook for another few minutes until everything is heated through.
Add the Cream of Mushroom Soup: Stir in that can of cream of mushroom soup, mixing everything until combined. Then add the sliced potatoes, stirring gently to coat them in that creamy goodness.
Simmer Down: Bring the mixture to a gentle simmer. Once it starts bubbling, reduce the heat to low, cover, and let it cook for about 15 minutes. This will help the potatoes soften and soak up all those delicious flavors.
Cheese, Please!: After the potatoes are tender, remove the lid and sprinkle the shredded cheese on top. Cover again and let it sit for a few minutes until the cheese is melted and bubbly!
Serve and Enjoy: Scoop out generous servings and enjoy your amazing Hamburger Supreme Casserole right away! It’s comforting, creamy, and satisfying your family is sure to ask for seconds!

Serving Suggestions
This Hamburger Supreme Casserole is fantastic on its own, but here are a few serving ideas to take it up a notch:
- Pair it with a fresh green salad or some steamed broccoli for balance.
- Crusty bread or garlic bread would make a lovely side, perfect for scooping up all that creamy goodness.
- For a tasty twist, top each serving with a dollop of sour cream and a sprinkle of fresh herbs!
Storage and Reheating
- How Long It Keeps: Leftovers can be stored in an airtight container in the fridge for up to three days.
- Reheating: The best way to reheat is in the oven at 350°F (175°C) for about 20 minutes until warmed through. You can also microwave it, but you may want to cover it to prevent drying out.
- Freezer Friendly: Yes! This casserole freezes beautifully. Just be sure to let it cool completely, then store it in a freezer-safe container. It’ll last for about 2-3 months. To reheat, thaw it overnight in the fridge, then bake as above.
