Ingredients
1 lb flank steak, thinly sliced
8 oz mushrooms (cremini or baby bella), sliced
1 yellow onion, diced
3 garlic cloves, minced
4 cups beef broth
2 tbsp olive oil
2 tbsp butter
2 cups green cabbage, thinly sliced
4 oz egg noodles
1/2 cup sour cream
2 tbsp fresh parsley, chopped (for garnish)
Salt and black pepper to taste
Instructions
1. Heat olive oil in a Dutch oven over medium-high heat. Season flank steak with salt and pepper, then sear in batches until browned but still pink inside. Remove and set aside.
2. In the same pot, sautée diced onions for 3–4 minutes, then add garlic and cook 1 minute more. Add mushrooms and cook until browned and reduced.
3. Pour in beef broth, scraping up brown bits from the bottom. Simmer for 10–15 minutes.
4. In a separate skillet, melt butter and sautée shredded cabbage until tender and golden. Cook egg noodles in a separate pot according to package instructions. Combine with cabbage and season lightly with salt.
5. Return the steak and juices to the pot. Simmer briefly to heat through. Taste and adjust seasoning.
6. To serve, ladle soup into bowls, top with sour cream and fresh parsley. Serve cabbage noodles on the side or stirred in.
Notes
Use a sharp knife and slice flank steak against the grain for maximum tenderness.
Don’t overcook the steak—just a quick sear and short simmer will keep it juicy.
For extra richness, stir a little sour cream into the broth before serving.
