Italian Steak with Garlic Butter and Peppers
Ingredients
- 4 1-inch thick top sirloin steaks (about 6 ounces each)
- Olive oil
- Salt and freshly ground pepper
- 3 tablespoons butter
- 1/2 cup onion, chopped
- 4 cloves garlic, minced
- 1/4 teaspoon crushed red pepper flakes
- 1/3 cup mild banana pepper rings, drained and chopped (see notes)
- 2 tablespoons liquid from the pepper rings
- 1 tablespoon chopped fresh parsley for garnish
Instructions
- Brush both sides of the steaks with a little olive oil and season with salt and pepper.
- Film the bottom of a large frying pan with olive oil and heat over medium-high heat. Add the steaks and sear lightly on both sides, about 2 minutes total. Transfer to a plate and set aside.
- Reduce the heat to medium, melt the butter and add the onion. Sauté until the onion is soft and translucent, 4 to 5 minutes.
- Add the garlic and sauté until barely golden, stirring constantly, 1 to 1-1/2 minutes longer.
- Add the crushed red pepper and banana peppers and combine well. Continue cooking for 1 to 2 minutes, then add the reserved liquid from the pepper rings.
- Return the steaks to the pan and turn several times to coat with the garlic butter-pepper mixture.
- Continue cooking, turning frequently, until the liquid in the pan has evaporated and the steak is cooked to your liking, about 3 minutes longer for medium rare.
- Transfer the steaks to a serving platter and allow to rest for 5 minutes. Top each with a portion of the pepper mixture, garnish with chopped parsley and serve.
