Start by seasoning your steaks generously with salt and pepper. This simple seasoning lays the foundation for bold, natural flavors. Heat up your skillet over medium-high heat with a drizzle of oil. Once the skillet is hot, sear the steaks on both sides until golden-brown. Remove them from the skillet and set them aside to rest. 🥩

Using the same skillet (because flavor is king here!), melt some butter and toss in your thinly sliced onions. Cook them low and slow until they become golden-brown and release that irresistible caramel aroma. This step takes patience, but the payoff is worth it. 🌟

Sprinkle flour over the sautéed onions and stir continuously until it forms a roux. Gradually whisk in beef broth, making sure there are no lumps. Add Worcestershire sauce and a few sprigs of thyme for extra depth of flavor. Allow the gravy to simmer until it thickens into a velvety sauce. 🥣

Place the steaks back into the skillet, spooning the luscious onion gravy over them. Simmer for a few minutes so the steak soaks up all that gravy goodness. Make sure every inch is smothered for maximum flavor! 😍

Plate up the steak with a side of mashed potatoes or a warm crusty baguette to soak up the gravy. Garnish with a sprig of thyme or a sprinkle of parsley for that finishing touch. 🍽️
