Ready in: 15 mins

Ingredients

Makes: 1 steak

• 1 flat iron steak (or more)
• Salt and pepper
• 1 teaspoon canola or vegetable oil
• 1 (4 1/2 ounce) jar sliced mushrooms, drained
• 1 teaspoon minced garlic
• 1/2 cup prepared French onion dip
• 2 tablespoons half-and-half
• 1/2 teaspoon minced chives
• 1/4 teaspoon black pepper

Preparation method

Prep: 5 mins | Cook: 10 mins

1. Season steak with salt and pepper on both sides.
2. Heat your gas or charcoal grill to high (Here’s how to tell if it’s high: Hold your hand about four inches above the cooking surface. After 2 to 3 seconds, the heat will force you to pull your hand away.)
3. Place the steak on the grill. Use these cooking times to cook your steak to medium: 2 to 3 minutes per side for a 1/2 inch thick steak, 4 to 6 minutes per side for a 1 inch thick steak, 6 to 9 minutes per side for a 1 1/2 to 2 inch thick steak.
4. While steak is grilling, heat oil in skillet over medium heat. When oil is hot, add mushrooms and garlic and cook, stirring, for 3 minutes. Add remaining ingredients, stir, and cook for another 3 minutes until heated through.
5. Take the steak off the grill. Let the meat rest 2 to 3 minutes to allow the juices to reabsorb into the steak. Pour creamy sauce over steak and serve.Note

Sauce makes about 1 cup of sauce.
