Marinated Sirloin Steak Tips with Peppers and Onions

Sirloin steak tips are an affordable cut of beef that are incredibly easy to prepare. Marinating the steak tips before cooking elevates the flavor of the steak. The sear on these Marinated Sirloin Steak Tips with Peppers and Onions is all possible due to cooking them in a cast iron skillet. Serve it with rice or potatoes and a salad for a complete delicious meal.

You might think the only way to get a char on steak and vegetables is with a grill, but a searing hot cast iron skillet can work just as well. This is especially useful if you live in a seasonal cold climate where you can’t grill outside. Sirloin steak tips are an affordable cut of meat which you can buy precut in chunks, slices, or in a steak form to cut them yourself. The advantage of cutting them yourself is that you can cut them the size you want. I like my steak tips cut in large 1 1/2-inch chunks but if you prefer to cut them smaller then cut them in 1-inch chunks.

WHAT ARE SIRLOIN STEAK TIPS?

Sirloin steaks or steak tips actually come from the round not the sirloin section of the cow which is a very lean cut. Buy sirloin steak to cut yourself or sirloin steak tips that are precut. DO NOT BUY SIRLOIN ROAST or STEW MEAT that has been cut into chunks. It is a meat cut that needs to be cooked low and slow and turn out super tough to chew if you try to use it in this recipe. You can also ask the butcher for help and tell them what you are planing to make just in case.

The steak tips are first marinated for deep flavor and and act as a tenderizer. They are seared in batches so that the meat will sear instead of steaming. The vegetables cook with water in the same skillet after the steak to collect some of the charred bits. So make sure you have a lid that you can place over your 12-inch cast iron skillet because the vegetables will be cooked first covered, then uncovered to evaporated the water and brown the vegetables. Feel free to use any color of bell pepper or a combination.

In the pictures, I used red bell peppers and yellow onions. I love serving Marinated Sirloin Steak Tips with Peppers and Onions with Jasmine or Basmati rice but some other options might be to serve it with mashed potatoes, diced potatoes, cauliflower rice, or simply on it’s own.

HOW TO MAKE MARINATED SIRLOIN STEAK TIPS WITH PEPPERS AND ONIONS

• Make the marinade: In a large bowl, whisk together ¼ cup oil, garlic, Worcestershire, lemon zest and juice, 1 tsp salt, and ½ tsp ground black pepper.
• Reserve 2 Tablespoons marinade; set aside.

• Add the steak tips to the bowl with the marinade; toss well and cover with plastic wrap or a lid.
• Refrigerate for 30 minutes to 1 hour, stirring the steak halfway through the marinating.
• While the steak is marinating, place a 12-inch cast-iron skillet on the middle rack of the oven and heat the oven to 500°F.
• Remove the steak tips from the marinade and pat dry with paper towels and remove any garlic pieces.
• When the oven reaches 500°F, remove the skillet from the oven, turn off the oven, and place over medium heat on the stove top.

• Add 2 Tablespoons oil and heat until the oil is shimmering.
• Place half of the steak tips in the skillet and cook until well browned on all sides (130°F to 135°F for medium done), about 8 minutes.
• Transfer to a quarter baking sheet or plate and tent loosely with foil.
• Add another 1 Tablespoon oil and repeat browning the other half of the steak tips.
• Transfer to the baking sheet and cover loosely with foil; set aside and make the vegetables.

• Heat the remaining 1 Tablespoon oil over medium-low heat until shimmering.
• Add the bell peppers, onions, ⅓ cup water, and ½ tsp salt.
• Cover and cook, stirring occasionally, until vegetables are softened, about 5 minutes.
• Uncover and continue to cook, stirring occasionally until water evaporates and vegetables are tender and lightly charred, about 5 to 10 minutes.

• Remove from heat and stir in reserved marinade, parsley, oregano plus any accumulated meat juices.

• Taste for salt and black pepper.
• Add the steak tips back to the skillet and stir.
• Serve the steak tips and vegetables over rice or mashed potatoes.
