Description
A quick and easy 15-minute keto-friendly dinner featuring tender sirloin steak cubes seared in a hot skillet and tossed in a rich, savory garlic butter sauce. Perfect for busy weeknights when you want restaurant-quality flavor without the fuss.
Ingredients
Scale
- 1.5 pounds sirloin steak, cut into 1-inch cubes
- 1 tablespoon neutral oil (avocado or vegetable oil)
- Salt and black pepper, to taste
- 4 tablespoons unsalted butter
- 4–5 cloves garlic, minced
- 1/2 teaspoon garlic powder
- 1 teaspoon dried parsley
- 1/4 teaspoon red pepper flakes (optional)
- Fresh thyme or rosemary (optional)
- 1 shallot, minced (optional)
Instructions
- Pat the steak cubes completely dry with paper towels and season generously with salt and pepper on all sides.
- Place a cast iron skillet over medium-high heat and let it get hot for about 2 minutes. Add the neutral oil and swirl to coat.
- Add the steak cubes to the pan in a single layer, ensuring not to crowd the pan. Cook in batches if necessary.
- Let the steak sit undisturbed for 2 minutes to form a crust, then flip and cook for another 2-3 minutes until browned and cooked to desired doneness (approx. 135°F for medium-rare). Remove steak from pan.
- Reduce heat to medium-low. Add butter to the pan. Once melted, add minced garlic, garlic powder, and red pepper flakes. Stir constantly for 30-60 seconds until fragrant and lightly golden, being careful not to burn.
- Return the steak bites to the pan and toss to coat evenly in the garlic butter sauce.
- Sprinkle with dried parsley and fresh herbs if using. Toss one final time to warm the herbs.
- Serve immediately while the butter is warm and glossy.
Notes
Do not crowd the pan to ensure proper browning; cook in batches if necessary. Pat the steak dry before seasoning to prevent steaming. Watch the garlic closely as it burns easily. For best results, serve immediately. Leftovers can be stored in the refrigerator for up to 3 days and reheated gently in a skillet.
