Beef Tips and Gravy

Step 1. Cover Potato with cold water in a pot and add half the Salt. Bring to a boil, then simmer until fork-tender, about 15 minutes. Drain, mash with Butter and Milk, then cover to keep warm.

Step 2. Meanwhile, season Beef Sirloin with the rest of the Salt and Black Pepper. Heat half the Olive Oil in a large skillet over medium-high heat. Sear the beef in batches until browned outside, about 2 minutes per batch; transfer to a plate.

Step 3. Add the rest of the Olive Oil, Mushroom, and Onion to the skillet. Cook over medium-high heat, stirring occasionally, until browned and softened, about 7 minutes.

Step 4. Stir in Garlic and All-Purpose Flour. Cook over medium heat, stirring, until the flour coats the vegetables and smells lightly toasted, about 1 minute.

Step 5. Gradually stir in Beef Stock and Worcestershire Sauce, scraping up the browned bits. Simmer over medium heat until the gravy thickens enough to coat a spoon, about 4 minutes.

Step 6. Return the beef and any juices to the skillet. Simmer gently until the beef is heated through and cooked to your liking, about 2 minutes, then remove from the heat.

Step 7. Divide the mashed potatoes among plates and spoon the beef and gravy over the top.
