Juicy beef steak topped with caramelized onions and a squeeze of fresh lime. This simple, high protein dish supports carnivore and clean eats lifestyles with minimal ingredients.
Slice the onions thinly and set aside. Pat the beef sirloin steak dry with paper towels.
Season both sides of the steak evenly with salt and black pepper.
Heat 1 tbsp of olive oil in a large skillet over medium-high heat. Sear the steak for about 3 minutes per side until a brown crust forms, then remove and set aside to rest loosely covered.
Add the remaining 1 tbsp olive oil to the same skillet. Lower heat to medium, add onions, and cook for 8–10 minutes, stirring often, until deep golden and caramelized, adjusting heat to avoid burning.
Return the steak to the skillet and pile caramelized onions on top. Cover and cook for 2–3 minutes more over low heat for flavors to meld. Remove from heat, finish with a squeeze of fresh lime, slice, and serve immediately.
