Instructions
Use a sharp knife to cut sirloin steaks into 1-inch pieces.
Marinade: In a small bowl whisk together the teriyaki sauce, brown sugar, olive oil, parsley, 3 clove minced garlic and red pepper flakes. Place into a plastic storage bag and refrigerate for several hours or overnight.
Prepare: Remove the sirloin tips from the marinade. Discard the marinade.
Heat a few drizzles of olive oil in a large cast iron or heavy skillet over medium-high heat. Add the sirloin tips in a single layer. Cook for 5-7 minutes until browned and to your preferred doneness. Season with 1 tsp of steak seasoning. Remove from the pan to a platter to rest.
To the skillet add the sliced bell peppers and onion wedges. Season with 1 tsp steak seasoning and black pepper to your taste. Add additional olive oil if needed.
Cook for 5 minutes scraping the brown bits from the bottom of the skillet. Cook until browned and crisp tender.
Add the sirloin beef tips back to the pan. Stir until heated through then serve.
Notes
Beef: You can't use beef stew meator chuck roast in place of steak for this recipe, it takes much longer to cook. It's ideal to stick with top sirloin steak for the best flavor. You could use new york strip steak.
Protein: You could adapt this recipe using chicken or pork tenderloin.
Peppers: You can use any variety of bell peppers that you like for this recipe.
Onion: You can also use red onion or yellow onion with each bringing their own unique flavor to the dish.
Teriyaki Sauce: For a steakhouse flavor you can use worcestershire sauce in place of teriyaki sauce.
Mushrooms: You could add sliced mushrooms to the pan along with the bell peppers or in place of the bell peppers.
Mexican Seasoning Options: At times, I'll turn this skillet sirloin tip sauté into a Tex-Mex creation seasoning the sirloin tips with fajita seasoning and a squeeze of lime juice. Wrap in warm tortillas and top with your favorite fajita fixings.
Asian Seasoning Option: To go full-out Asian flavors use an Asian seasoning in place of the steak seasoning, add a few dashes of teriyaki or soy sauce, a drizzle of hoisin sauce and a squeeze of fresh lime juice then serve it over cooked rice
Cook to Your Desired Doneness: Adjust the cooking time of the sirloin steak depending on the desired level of doneness that suits your family's taste. There's no one shoe fits all here.
AlternateServing Option: You can also stuff these sirloin tips with the peppers and onions on toasted hoagie rolls. Top them with sliced or shredded mozzarella cheese and and place them under the oven broiler just until the cheese melts for a gooey cheesesteak.
