These sautéed Sirloin Tips with Bell Peppers and Onions are a flavorful skillet dish packed with bold, savory goodness. Tender, marinated chunks of sirloin are perfectly seasoned and seared until they develop a deliciously charred crust, while staying juicy inside. Tossed with sweet onions and vibrant bell peppers, this dish comes together in just about 15 minutes making it as quick to make, as it is satisfying.

What are Sirloin Tips?

They’re essentially top sirloin steaks cut into bite-sized cubes, much like stew meat. Because beef tips cook quickly, they’re perfect for fast meals and stir-fry’s. To achieve a beautiful sear, use a smoking hot skillet and avoid flipping the pieces until they release easily with a gentle tug.

Easy Sirloin Tips with Bell Peppers and Onions Recipe

Sirloin tips are often overlooked for quick weeknight dinners, but when you catch them on sale, they’re a fantastic choice. I like to serve them with a baked or mashed potato and a side salad for a satisfying, no-fuss meal. Sometimes, I give them a Tex-Mex twist by adding fajita seasoning and a squeeze of lime, then wrap them in warm tortillas with a DIY toppings bar for the family.

You can also switch up the flavor profile with Asian-inspired seasonings and serve over rice, or pile them onto toasted sub rolls for a hearty sandwich. It’s a quick, family-friendly meal that never leaves leftovers behind.
