Season steak bites with salt and pepper.
Sear the Steak:
Heat olive oil in a skillet over medium-high heat. Sear steak bites in batches until browned on all sides and cooked to your desired doneness. Remove from the skillet and set aside.
Make Garlic Butter Sauce:
In the same skillet, melt butter. Add minced garlic and sauté until fragrant, about 30 seconds.
Combine and Finish:
Return steak bites to the skillet. Toss to coat in the garlic butter sauce and cook for an additional minute to heat through.
Serve:
Garnish with chopped parsley and a squeeze of lemon if desired. Serve immediately for juicy, buttery, garlicky perfection.
