Recipe Information
Ingredients
- 2 pieces ribeye steaks
- 2 tablespoons olive oil
- 2 tablespoons unsalted butter
- 2 cloves garlic cloves, minced
- 8 ounces cremini mushrooms, sliced
- 1 large yellow onion, thinly sliced
- 4 sprigs fresh thyme
- 1 teaspoon salt
- 1 teaspoon black pepper
- 0.25 cup beef broth (optional for deglazing)
Instructions
Take the ribeye steaks out of the refrigerator and let them come to room temperature for about 20 minutes. Pat them dry with a paper towel.
Season both sides of the steaks with 1/2 teaspoon salt and 1/2 teaspoon black pepper. Set aside.
Heat 1 tablespoon of olive oil and 1 tablespoon of butter in a large skillet over medium-high heat.
Once the skillet is hot, add the steaks and sear them for 3-4 minutes per side or until they reach your desired doneness (130°F for medium-rare). Use a meat thermometer for accuracy.
Remove the steaks from the skillet and cover them loosely with aluminum foil to rest.
Lower the heat to medium and add the remaining olive oil and butter to the same skillet.
Add the sliced onion and sauté for 3-4 minutes until translucent. Stir occasionally to avoid burning.
Add the garlic, fresh thyme sprigs, and sliced mushrooms. Continue cooking for another 8-10 minutes until the mushrooms are tender and golden, and the onions are caramelized.
If desired, deglaze the skillet by pouring in the beef broth and scraping the bottom of the pan to release any browned bits.
Season the mushroom and onion mixture with the remaining salt and pepper. Remove the thyme sprigs and discard.
Serve the steaks on plates and top with the sautéed mushrooms and onions. Optionally, garnish with a sprig of thyme.
Enjoy your keto-friendly steak meal!
