A quick and easy burger casserole featuring sautéed mushrooms, ground beef, and melty Swiss cheese, perfect for cozy weeknight dinners.

Ingredients

Scale
  • 1 lb (450 g) ground beef (80/20 preferred)
  • 8 oz (225 g) cremini or white mushrooms, cleaned and sliced
  • 8 oz (225 g) Swiss cheese, shredded (Emmental style recommended)
  • 1 medium onion, finely chopped
  • 2 cloves garlic, minced
  • 2 tbsp (28 g) unsalted butter
  • 1 tbsp Worcestershire sauce
  • Salt and black pepper, to taste
  • 2 large eggs
  • ½ cup (120 ml) milk (whole or 2%)
  • ¾ cup (90 g) breadcrumbs (plain or seasoned)
  • 2 tbsp fresh parsley, chopped (optional)

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. Melt 2 tbsp butter in a large skillet over medium heat. Add chopped onion and cook for 3-4 minutes until translucent. Add sliced mushrooms and minced garlic, cooking another 6-8 minutes until mushrooms are browned and moisture has mostly evaporated. Season lightly with salt and pepper.
  3. Push the veggies to the side and add ground beef to the skillet. Break it apart with a spatula and cook until no longer pink, about 5-7 minutes. Stir together with mushrooms and onions, then add 1 tbsp Worcestershire sauce, salt, and pepper to taste. Remove from heat and let cool slightly.
  4. In a medium bowl, whisk together 2 large eggs and ½ cup milk. Stir in ¾ cup breadcrumbs and 2 tbsp chopped parsley. Add the beef and mushroom mixture, stirring until combined evenly.
  5. Transfer the mixture to a greased 9×13 inch casserole dish. Sprinkle shredded Swiss cheese evenly over the top. Bake uncovered for 25-30 minutes until cheese is melted, bubbly, and just starting to brown. Let rest for 5 minutes before serving.

Notes

Do not rush sautéing mushrooms to avoid sogginess; brown them well for depth of flavor. Shred Swiss cheese fresh for better melting. Let casserole rest 5 minutes after baking for easier slicing. Can prepare mixture a day ahead and refrigerate; add extra baking time if cold. For gluten-free, substitute breadcrumbs with almond flour or gluten-free breadcrumbs. For low-carb, use crushed pork rinds or almond flour instead of breadcrumbs.
