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 well blended.
06 - Add the beef and mushroom mixture to the bowl; stir well to coat everything evenly with the 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 combined. Sprinkle over the cheese layer.
09 - Bake for 25–30 minutes or until the top is golden brown and the sauce is bubbly around the edges.
10 - Let stand 5 minutes before serving to allow the casserole to set for easier serving.
