How to Make a Tender Sirloin Tip Roast in a Crock-Pot

Sirloin steaks bring to mind a great piece of quickly grilled meat — but the name of a sirloin tip roast is a bit of a misnomer, as it's not a sirloin at all. Instead, it's the lean, inexpensive cut of meat, also known as a round tip roast or a knuckle roast, that's located next to the tip of the sirloin. This cut is served well by braising, making a slow cooker sirloin tip roast the smart way to go.

The Best Way to Cook a Sirloin Tip Roast

The boneless sirloin tip roast is cut from the rump of the cow, an area used for movement. Because that area is used so much, it's full of lean muscle rather than fat. This makes it a tougher cut of meat, rather than a tender cut such as a standing rib roast or a tenderloin.

Cuts of beef that are lean and tough like the sirloin tip roast should be cooked low and slow to break down the connective fibers that cause that toughness. As the collagen between the muscle fibers breaks down, the meat reaches that "fall-apart" texture that slow-cooked beef is known for. You can cook a roast like that in the oven for a few hours on a low setting, or you can set it and forget it to braise in a slow cooker.

Slow Cooker Sirloin Tip Roast Recipe

The finished product of a slow cooker sirloin tip roast looks much like a traditional pot roast, particularly if you braise the cut of beef with vegetables and potatoes.

Step 1: Heat olive oil in a large pan over high heat. Add the sirloin tip roast to the pan and brown it on all sides. Although this step can be skipped if you're in a hurry, browning the beef before cooking improves the flavor of the final meal.

Step 2: In a small bowl, combine a tablespoon of olive oil and a teaspoon of Worcestershire sauce. Add minced garlic, fresh rosemary, salt and pepper.

Step 3: Put the roast in the slow cooker and then brush it with the olive oil and Worcestershire sauce mixture. Arrange two quartered onions around the beef, and pour in 1 cup of beef broth to the slow cooker.

Step 4: Cover the slow cooker and set it to cook on low for 8 hours. Halfway through cooking, open the lid and arrange chopped russet potatoes and carrots around the slow cooker sirloin tip roast. Return the cover to the slow cooker.

Slow Cooker Sirloin Tip Roast Variations

Like other cuts of beef, a sirloin tip roast is versatile. Play around with the cut of beef or the ingredients that you add to the slow cooker to change things up and create a different meal.

  • If you like spicy food, add a healthy dose of crushed red pepper flakes to the slow cooker sirloin tip roast recipe.
  • To change the flavor profile of the sirloin tip roast, replace the beef broth with a cup of bold red wine or dark beer.
  • After the slow cooker sirloin tip roast is finished cooking, drain the liquid from the Crock-Pot into a small saucepan. Bring the liquid to a boil and then let it simmer and reduce to a thick gravy. To speed up the thickening, mix 1 tablespoon of cornstarch with 1 tablespoon of cold water or beef broth and whisk it into the simmering water. Serve the gravy over the roast.
  • Cut the sirloin tip roast into small chunks and use it as the protein in your favorite beef stew recipe. Incorporate extra vegetables, such as mushrooms and celery, to make it heartier and more nutritious.
