Ingredients

Scale

For the Steak & Mushrooms:

  • 2 ribeye or sirloin steaks (about 1-inch thick)
  • 2 tbsp olive oil
  • 2 tbsp butter
  • 8 oz mushrooms (sliced) – cremini or baby bella work great
  • 3 cloves garlic (minced)
  • 1 tsp fresh thyme (or ½ tsp dried)
  • 1 tsp fresh rosemary (or ½ tsp dried)
  • Salt and black pepper (to taste)
  • ¼ cup beef broth
  • 2 tbsp heavy cream (optional, for extra richness)

Instructions

  • Prepare the Steaks – Take the steaks out of the fridge 30 minutes before cooking to bring them to room temperature. Pat dry and season both sides with salt and black pepper.
  • Sear the Steaks – Heat 1 tbsp olive oil in a skillet over medium-high heat. Cook steaks 3-5 minutes per side, depending on doneness. Add 1 tbsp butter in the last minute and spoon over the steaks. Remove and let rest for 5-10 minutes.
  • Cook the Mushrooms – In the same skillet, add the remaining 1 tbsp olive oil and 1 tbsp butter. Sauté mushrooms for 5 minutes. Add garlic, thyme, and rosemary. Cook for 1-2 more minutes.
  • Deglaze the Pan – Pour in beef broth, scraping up browned bits. Let simmer for a minute, then stir in heavy cream if using.
  • Finish & Serve – Slice the rested steaks and place them back in the skillet. Spoon the sauce over them and heat for 1-2 more minutes. Serve hot with keto-friendly sides.

Notes

  • For extra richness, add a splash of heavy cream to the mushroom sauce.
  • Use a meat thermometer for perfect steak:
    • Rare: 125°F (52°C)
    • Medium-Rare: 135°F (57°C)
    • Medium: 145°F (63°C)
  • Pair with keto sides like cauliflower mash, roasted asparagus, or cheesy garlic rolls.
