Instructions
Generously salt and pepper the beef chunks. Heat the olive oil over medium in a Dutch oven or large skillet. Brown the beef chunks on all sides. Work in batches so you do not crowd the pan adding more oil if needed. Plate the browned beef, reserve any pan juices and cover to keep warm.
Melt the butter in the pot. Add the mushrooms and cook for a few minutes. Add the onions and cook until they start to soften and the mushrooms turn a nice golden brown. Add the garlic and cook for 1 additional minute. Remove everything from the pan and place it on the plate with the beef chunks.
Pour the red wine into the pot and scrape it with a wooden spoon to get all those tasty brown bits from the bottom and sides of it. Gently simmer the wine and reduce it by half. Stir in the beef broth, Worcestershire sauce, and soy sauce. Bring the mixture to a boil and then reduce to a simmer.
Combine the cornstarch and the water in a small bowl or measuring cup. Slowly pour it into the simmering mixture while stirring.
Add the mushroom mixture and beef tips with any pan juices back to the skillet and gently simmer for 10 minutes to thicken the mixture and finish cooking the beef. Season with salt and freshly cracked black pepper to taste. Serve over noodles, rice, or mashed potatoes. Garnish with chopped fresh thyme or parsley.
