How to Make Mushroom Cheeseburger Casserole

Step 1: Sauté the Beef and Mushrooms

Heat a large skillet over medium-high, tossing in the ground beef and breaking it up as it cooks. When it starts to brown, add the mushrooms and onions, stirring until the mushrooms are soft and the onions are translucent. Toss in the garlic for the last minute so it gets fragrant but doesn’t burn. This base is where the Mushroom Cheeseburger Casserole gets all its meaty, savory richness.

Step 2: Cook the Noodles

While the beef and mushrooms are sizzling away, bring a big pot of salted water to a boil. Drop in your egg noodles and cook until just shy of al dente—they’ll finish softening in the oven. Drain them well so your casserole isn’t watery, and set aside.

Step 3: Mix Up the Sauce

In a large bowl, whisk together the cream of mushroom soup, milk, ketchup, Dijon mustard, salt, and pepper. This creamy, tangy mixture will coat the noodles and beef, making every forkful extra luscious. Feel free to give it a little taste and adjust for your personal preference.

Step 4: Combine Everything

Toss the beef-mushroom mixture, cooked noodles, about two-thirds of the cheddar cheese, and the creamy sauce together in your biggest mixing bowl (or right in the casserole dish, if it fits). Stir gently to make sure everything is well distributed—nobody likes a bite without cheese! Spread the mixture into a greased casserole dish.

Step 5: Bake to Perfection

Sprinkle the remaining cheddar cheese generously over the top, then bake in a preheated oven at 350°F for about 25-30 minutes. You’re looking for it to get bubbly around the edges and gloriously gooey up top. If you love a golden crust, switch on the broiler for the last couple minutes, but keep a close eye so it doesn’t scorch.

How to Serve Mushroom Cheeseburger Casserole

Garnishes

A shower of freshly chopped parsley or even some sliced scallions brings a touch of color and freshness that balances the heartiness of Mushroom Cheeseburger Casserole. For extra classic burger vibes, try a sprinkle of sesame seeds before serving.

Side Dishes

Pair this casserole with a crisp green salad, steamed broccoli, or even roasted sweet potato wedges. These sides add brightness and crunch, keeping dinner light and balanced while complementing the savory richness of the main dish.

Creative Ways to Present

For family-style fun, spoon the casserole into shallow bowls and invite everyone to top theirs with favorite cheeseburger fixings—think chopped pickles, crumbled bacon, diced tomatoes, or shredded lettuce. Kids especially love adding their own twist to Mushroom Cheeseburger Casserole!

Make Ahead and Storage

Storing Leftovers

Leftovers of Mushroom Cheeseburger Casserole keep beautifully in the fridge for up to 4 days. Simply transfer to an airtight container (or cover the dish tightly with foil or a lid), and you’ll have a ready-to-go lunch or dinner on busy days.

Freezing

This casserole is a meal-prepper’s dream. You can assemble it up to the point before baking, wrap it well, and freeze for up to 2 months. Thaw overnight in the fridge, then bake as usual. Already-baked leftovers can also be frozen; portion them for easy grab-and-reheat meals.

Reheating

Warm individual servings in the microwave, or reheat larger amounts in a covered dish at 325°F until hot and bubbling. If the casserole seems dry after storage, a splash of milk or broth stirred in before reheating will bring the creamy texture right back.

FAQs

Can I substitute the ground beef with turkey or chicken?

Absolutely! Lean ground turkey or chicken both work nicely in Mushroom Cheeseburger Casserole if you’d like a lighter alternative. Just be sure to season generously, since poultry is a bit milder than beef.

Cremini (baby bella) and white button mushrooms are both excellent choices. You can also mix in portobello or even add a handful of wild mushrooms for extra dimension if you’re feeling adventurous.

Can this be made gluten-free?

How can I make this casserole vegetarian?

To make a meatless version, simply replace the ground beef with extra mushrooms or a plant-based ground meat alternative. The casserole’s bold flavors hold up beautifully with the swap!

Is it possible to add more vegetables?

Go for it! Diced bell pepper, spinach, or zucchini are tasty additions. Simply sauté extra veggies with the mushrooms and onions so everything mingles together. Mushroom Cheeseburger Casserole is easy to personalize.
