Description
A quick and easy weeknight dinner that combines juicy ground beef, earthy mushrooms, and melted Swiss cheese into a comforting casserole. Perfect for busy families, this one-dish meal delivers classic burger flavors with minimal cleanup.
Ingredients
Scale
- 1.5 lbs 80/20 ground beef
- 8 oz cremini or button mushrooms, sliced
- 1 large yellow onion, diced
- 2 cloves garlic, minced
- 1.5 cups shredded Swiss cheese
- 1 cup panko or regular breadcrumbs
- 1/2 cup beef broth
- 1 tablespoon Worcestershire sauce
- 1 teaspoon Dijon mustard
- 2 tablespoons butter
- Salt and black pepper to taste
- Pinch of thyme (optional)
Instructions
- Preheat oven to 375°F (190°C) and grease a 9×13 inch baking dish.
- Melt butter in a large skillet over medium heat. Sauté diced onion until translucent (about 5 minutes).
- Add sliced mushrooms and cook until they release water and brown (8-10 minutes). Add garlic in the last minute.
- Push vegetables to the side or remove from pan. Add ground beef and cook until browned (5-7 minutes). Drain excess fat if necessary.
- Return vegetables to the pan. Stir in beef broth, Worcestershire sauce, Dijon mustard, salt, pepper, and thyme.
- Pour the meat and vegetable mixture into the prepared baking dish and spread evenly.
- Sprinkle shredded Swiss cheese over the top, followed by breadcrumbs.
- Bake for 20-25 minutes until cheese is melted and bubbly and breadcrumbs are golden brown. Optionally broil for 2 minutes for extra crispiness.
- Let cool for 5 minutes before serving.
Notes
For best results, use fresh mushrooms and shred your own Swiss cheese for better melting. Do not overcrowd the pan when sautéing mushrooms to ensure they brown properly rather than steam. Let the casserole rest for 5 minutes after baking to allow it to set.
