Ingredients
Directions
Preheat the oven to 350 degrees F (175 degrees C). Grease a baking sheet with oil.
Combine ground sirloin, onion, bread crumbs, Worcestershire sauce, egg, salt, and black pepper in a bowl until well mixed. Shape into golf ball-sized meatballs; place on the prepared baking sheet.
Bake in the preheated oven until meatballs are no longer pink in centers, about 15 minutes.
Melt 2 tablespoons butter in a large skillet over medium heat. Add mushrooms; cook and stir until soft, about 10 minutes. Push mushrooms to one side of the skillet.
Melt remaining 2 tablespoons butter in the same skillet. Whisk in flour; cook until it begins to brown lightly and smell fragrant. Whisk in broth and mustard; bring to a boil. Add meatballs; cook until some sauce is absorbed, 10 to 15 minutes. Off heat, stir in sour cream until combined.
