Ingredients
– 2 Tbsp (28 g) unsalted butter
– 1 lb (450 g) beef sirloin, trimmed and thinly sliced
– Salt and freshly ground black pepper, to taste
– 8 oz (225 g) crimini mushrooms, sliced
– 1 medium sweet onion, diced (about 150 g)
– 3 cloves garlic, minced
– 2 Tbsp (30 g) tomato paste
– 1 Tbsp (15 ml) Worcestershire-style sauce (or soy/fish sauce as a substitute)
– 5 cups (1.2 L) low-sodium beef stock (or chicken stock)
– 1.5 cup (150 g) dried egg noodles
– 0.5 cup (120 ml) sour cream
– 2 Tbsp (16 g) all-purpose flour (or 1-to-1 gluten-free flour blend)
– Chopped fresh parsley, for garnish
Instructions
1-Melt the butter in a large pot over medium-high heat. Season the sliced beef with salt and pepper, then sear for 1-2 minutes per side until browned but still pink. Remove and set aside.
2-Add the mushrooms, diced onion, and minced garlic to the pot; sauté for about 3 minutes until softened. Season lightly to bring out the flavors.
3-Stir in the tomato paste and Worcestershire-style sauce; cook for 1 minute to blend everything nicely.
4-Pour in the beef stock, bring to a boil, then add the dried noodles. Reduce to a simmer and cook 5-7 minutes, or until the noodles are al dente.
5-In a small bowl, whisk together the sour cream and flour. Dilute this mixture with 1 cup of the hot soup, then stir the slurry back into the pot. Cook 1-2 minutes until the broth thickens slightly.
6-Return the seared beef to the pot and simmer a few minutes until the meat is heated through.
7-Adjust seasoning with additional salt and pepper if needed. Serve hot, topped with chopped parsley.
Notes
🔥 Sear the beef quickly over high heat to lock in flavor while keeping it tender.
❄️ Cool the soup completely before refrigerating; omit noodles if you plan to freeze for longer storage.
🥄 For a richer broth, stir in a splash of Dijon mustard or a dash of sherry before serving.
