# Steps:

01 - Preheat oven to 375°F. Grease a 9x13-inch baking dish with butter or cooking spray.
02 - In a large skillet over medium heat, cook ground beef until browned and crumbly, about 6–8 minutes. Drain excess fat if necessary.
03 - Add chopped onion and garlic to the skillet; cook 2–3 minutes until softened and fragrant.
04 - Stir in sliced mushrooms; cook another 5 minutes until tender and liquid has mostly evaporated.
05 - In a large bowl, combine cream of mushroom soup, sour cream, milk, Worcestershire sauce, dried thyme, salt, and pepper. Whisk until smooth and fully incorporated.
06 - Add the beef and mushroom mixture to the bowl; stir well to coat everything evenly with the creamy sauce.
07 - Transfer the mixture to the prepared baking dish. Sprinkle evenly with shredded cheddar cheese.
08 - In a small bowl, mix breadcrumbs (or crushed crackers) with melted butter until evenly coated. Sprinkle over the cheese layer.
09 - Bake for 25–30 minutes or until the top is golden brown and the filling is bubbly around the edges.
10 - Let stand 5 minutes before serving to allow the casserole to set for easier scooping.

# Expert Advice:

01 -
  • Its the kind of comfort food that makes everyone at the table actually slow down and talk
  • The crispy buttered topping against that creamy beef filling is ridiculously satisfying
  • You can assemble it ahead and just pop it in the oven when walk in the door
02 -
  • Dont skip draining the beef if its especially fatty, or youll end up with a greasy layer on top
  • The mushrooms release a surprising amount of liquid, so be patient and let it cook off or your casserole will be soggy
  • If you make this ahead and refrigerate it, add at least 5 extra minutes to the baking time since it starts cold
03 -
  • Mix a pinch of smoked paprika into the beef while cooking for a subtle smoky depth that people cant quite identify
  • Use crushed buttery crackers instead of breadcrumbs for an even more decadent topping that gets extra crispy
