Cooking the Soup

Sautéing the Aromatics
Heat olive oil in a large pot or Dutch oven over medium heat. Add onion, carrots, and celery, cooking until softened, about 5-7 minutes. Stir in garlic and cook for an additional minute.
Building Flavor
Sprinkle flour over the vegetables and cook for 1-2 minutes, stirring constantly. This step helps thicken the soup and adds depth of flavor. Pour in beef broth, stirring well to combine. Add milk, salt, pepper, thyme, and bay leaf. Bring the mixture to a boil, then reduce heat to low, allowing it to simmer for 15 minutes.
Adding the Steak and Potatoes
Stir in the sliced leftover steak and diced baked potatoes. Cook for an additional 10-15 minutes, or until the potatoes are heated through and the steak is warmed. Taste and adjust seasoning if needed.

Serving
Ladle the soup into bowls, garnish with fresh parsley (if using), and serve with crusty bread or a side salad. This leftover steak and baked potato soup is best enjoyed with loved ones on a cozy night in.
