Sizzling Steak Beneath Savory Onion Gravy: A Culinary Delight

1. Heat the Skillet. Place a heavy‑bottomed skillet over medium‑high heat for 3 minutes. Add the olive oil and let it shimmer—this temperature is ideal for a quick, caramelized crust without burning.
2. Sear the First Side. Lay the steaks away from you to avoid splatter. Cook undisturbed for 4 minutes; a deep golden‑brown crust will form, sealing in juices.
3. Flip and Sear. Turn the steaks and sear the other side for another 3‑4 minutes. Once both sides are beautifully browned, remove the steaks to a plate and tent with foil.

Building the Onion Gravy

1. Cook the Onions. Reduce heat to medium and add butter to the same skillet. Once melted, stir in the sliced onions. Cook, stirring occasionally, for 8‑10 minutes until they turn soft, translucent, and start to caramelize.
2. Add Garlic & Thyme. Toss in the minced garlic and thyme leaves. Sauté for 30 seconds—just long enough to release fragrance without burning.
3. Create the Roux. Sprinkle the flour over the onions, stirring constantly for 2 minutes. This forms a light roux that will thicken the gravy without lumps.
4. Deglaze & Simmer. Gradually whisk in beef broth, Worcestershire sauce, and soy sauce, scraping up any browned bits (fond) from the pan. Bring to a gentle simmer; the mixture will thicken in 3‑4 minutes, coating the back of a spoon.

Finishing in the Oven

Return the seared steaks to the skillet, nestling them into the onion gravy. Transfer the whole pan to a pre‑heated 375°F (190°C) oven. Bake for 12‑15 minutes, or until an instant‑read thermometer registers 130°F for medium‑rare (or your preferred doneness). Baste the steaks once halfway through to infuse extra flavor. Remove from the oven, let rest 5 minutes, then slice against the grain and serve drizzled with the remaining gravy.
