### Instructions:

**Step 1: Prepare the Beef**
Season the beef slices with salt, pepper, and paprika. In a large pot or Dutch oven, heat 1 tbsp butter or oil over medium-high heat. Quickly sear the beef strips until browned but not fully cooked. Remove and set aside.

**Step 2: Sauté Vegetables**
In the same pot, add remaining butter or oil. Sauté onions and garlic until translucent. Add mushrooms and cook until browned and softened.

**Step 3: Create the Base**
Sprinkle flour over vegetables and stir to coat evenly. Slowly pour in beef broth, stirring constantly to avoid lumps. Bring to a simmer and cook until broth thickens slightly.

**Step 4: Combine Ingredients**
Return beef to the pot. Simmer gently for 10 minutes until beef is tender and flavors meld.

**Step 5: Add Sour Cream**
Reduce heat to low. Temper the sour cream by mixing a few tablespoons of hot soup into it, then stir the mixture back into the pot. Do not boil after adding sour cream to avoid curdling.

**Step 6: Final Seasoning and Serve**
Adjust seasoning with salt and pepper. If using, add cooked egg noodles. Garnish with fresh parsley and serve hot.
