Instructions

1. 1

   Coat a 9x13-inch baking dish with cooking spray; set aside.

2. 2

   Bring a large pot of salted water to a boil over high heat. Add the egg noodles and cook until al dente according to the package directions, about 6 minutes. Drain and set aside.

3. 3

   Heat the oil in a large nonstick skillet over medium-high heat. Add the sliced steak, salt, and pepper and cook, stirring occasionally, until the beef is browned and mostly cooked through, about 5 minutes.

4. 4

   Add the mushrooms, onions, and garlic to the skillet. Cook, stirring occasionally, until the mushrooms and onions are softened, about 5 minutes. Add the broth and bring to a boil. Reduce the heat to medium and simmer, stirring occasionally, until slightly reduced, about 3 minutes. Add the cream of mushroom soup and sour cream, plus the optional dill, mustard, and Worcestershire, if using; stir until evenly combined.

5. 5

   Remove the skillet from heat and add the reserved cooked noodles, tossing to coat. Pour into the baking dish, spread in an even layer, and cover tightly with aluminum foil.

6. 6

   Bake the casserole until bubbles form around the edges, about 25 minutes. Remove the foil and garnish with additional dill, if desired, and serve. Refrigerate leftovers in an airtight container for up to 3 days. Love the recipe? Leave us stars and a comment below!
