Instructions

1. Step 1: Heat 2 tbsp olive oil in a large deep skillet or Dutch oven over medium-high heat. Add 1 lb thinly sliced sirloin steak seasoned with 1 tsp salt and 1/2 tsp black pepper. Sear steak for 2-3 minutes until browned but not fully cooked; remove steak and set aside.
2. Step 2: In the same pot, add 1 diced medium yellow onion and 8 oz sliced baby bella mushrooms. Sauté for 5 minutes until mushrooms release moisture and onions soften. Add 3 minced garlic cloves and cook for 1 minute until fragrant.
3. Step 3: Sprinkle 2 tbsp all-purpose flour over the vegetables and stir for 1 minute to create a roux. Slowly pour in 3 cups beef broth while stirring to avoid lumps. Add 1 tbsp Dijon mustard and 1 tbsp Worcestershire sauce and bring mixture to a simmer.
4. Step 4: Add 8 oz egg noodles and the seared steak back into the pot. Cover and cook for 8-10 minutes, stirring occasionally, until noodles are tender and steak is cooked through.
5. Step 5: Remove from heat and stir in 1/2 cup sour cream until creamy and smooth. Garnish with 2 tbsp chopped fresh parsley before serving.
