Brown the Beef:
Heat olive oil in a large pot or Dutch oven over medium-high heat. Add beef cubes and sear until browned on all sides. Work in batches if needed.
Sauté Aromatics:
Add the chopped onion and cook 3–4 minutes until softened. Stir in minced garlic and cook for 1 minute until fragrant.
Pour in beef broth, 1 cup water, and Worcestershire sauce. Add thyme, salt, and pepper. Bring to a boil, then reduce heat to low. Cover and simmer for about 1 hour, or until beef is tender.
Cook Noodles:
Stir in the egg noodles and continue cooking, uncovered, for 8–10 minutes until noodles are tender. Stir occasionally to prevent sticking.
Optional Thickening:
If you prefer a thicker sauce, whisk cornstarch with 2 tablespoons water to make a slurry. Stir it into the pot during the last 5 minutes of cooking, and simmer until thickened.
Taste and adjust seasoning. Garnish with fresh parsley before serving warm.
