Ingredients

  • 1 lb thinly sliced steak ribeye or sirloin
  • 1 medium yellow or sweet onion thinly sliced
  • 1 bell pepper green, red, or yellow, thinly sliced
  • 4 –6 slices provolone cheese or keto-friendly alternative
  • 1 tbsp avocado oil or butter
  • 1 tbsp keto-friendly Worcestershire sauce
  • Salt to taste
  • Black pepper to taste
  • Optional: 1/2 tsp garlic powder
  • Optional: 1/2 cup sliced mushrooms
  • Optional: 1 small jalapeño sliced

Instructions

Prep Ingredients

  • Freeze steak for 20 minutes for easier slicing. Slice steak thinly against the grain. Prepare onion and pepper by slicing thinly.

Sauté Veggies

  • Heat oil in a large skillet over medium-high. Add onions and bell peppers. Sauté for 5–6 minutes until soft and slightly browned. Remove and set aside.

Cook Steak

  • In the same skillet, add steak strips. Season with salt, pepper, and garlic powder (if using). Cook 2–3 minutes until browned.

Combine & Melt Cheese

  • Return veggies to skillet. Add Worcestershire sauce and stir to combine. Top with provolone cheese slices. Cover and melt for 1–2 minutes.

Serve Immediately

  • Serve hot in bowls, lettuce cups, or over cauliflower rice.

Notes

  • Partially freezing steak makes it easier to slice thinly.
  • Use provolone slices (not shredded) for a gooey, authentic melt.
  • For extra richness, swap avocado oil for butter.
  • Serve with roasted cabbage, lettuce wraps, or cauliflower rice.
