A quick and easy keto-friendly ribeye steak recipe topped with a rich, herbaceous garlic butter, perfect for Father’s Day or any special occasion.

Ingredients

Scale
  • 1 ribeye steak (1-inch thick, about 12 ounces/340g, preferably grass-fed)
  • 4 tablespoons (56g) unsalted butter, softened
  • 3 cloves fresh garlic, finely minced or grated
  • 1 tablespoon fresh parsley, finely chopped
  • 1 teaspoon fresh thyme, finely chopped (optional)
  • Coarse sea salt, to taste
  • Freshly ground black pepper, to taste
  • 1 tablespoon olive oil, for searing
  • A pinch of lemon zest (optional)

Instructions

  1. Prepare the garlic butter: In a small bowl, combine 4 tablespoons (56g) of softened unsalted butter with the minced garlic, chopped parsley, thyme, and a pinch of lemon zest if using. Mix until evenly combined. Cover and refrigerate for at least 30 minutes to let flavors meld. (If short on time, use immediately.)
  2. Season the ribeye: Take the ribeye out of the fridge about 20 minutes before cooking to come to room temperature. Pat dry with paper towels. Generously season both sides with coarse sea salt and freshly ground black pepper.
  3. Heat your skillet: Place a cast iron pan over medium-high heat and add 1 tablespoon of olive oil. Heat until the oil just starts to smoke.
  4. Sear the steak: Place the ribeye in the hot pan. Cook undisturbed for 3-4 minutes for medium-rare, then flip and sear the other side for another 3-4 minutes. Use tongs to flip, avoid piercing the meat.
  5. Check doneness: Use a meat thermometer to check for 130°F (54°C) for medium-rare. Adjust cooking time if a different doneness is preferred.
  6. Rest the ribeye: Transfer steak to a plate and loosely tent with foil. Rest for 5-7 minutes to allow juices to redistribute.
  7. Top with garlic butter: While resting, scoop a generous dollop of prepared garlic butter onto the hot steak to melt and coat.

Notes

For best flavor, prepare garlic butter ahead and let it chill to meld flavors. Use a meat thermometer for perfect doneness. Let steak rest to keep it juicy. If pan smokes too much, lower heat. Avoid piercing steak to retain juices. Dairy-free option: substitute butter with ghee or plant-based butter.
