If I had to pick one of my favorite recipes from my childhood to define it, it would probably be this great recipe for fall-apart shredded beef sirloin tip roast. When you cook this cut of beef over low heat for a long period of time, you get perfectly tender, fall-apart meat perfect for sandwiches. Growing up, we called this recipe “Rock Elm Beef” because this style of beef was the go-to meal for the rural church dinners in Rock Elm, WI where our family farm was located.

If you’d like to learn how to cook fall apart sirloin tip roast, this is hands down the best way to do so. Sirloin tip roast is a lean cut that comes from the front end of the rear leg. While it is traditionally a tougher cut of meat, it becomes juicy and tender when you give it ample time to cook over low heat. Slow cooking with liquid gives the connective tissues ample time to break down, creating a more tender, flavorful roast, making the slow cooker the perfect cooking method!

This recipe is one you’ll want to make again and again, and the best part is how simple it is! It has the added bonus of making your house smell incredible all day long. The whole family is going to love this incredibly tender beef.


To make this deliciously tender fall-apart sirloin tip roast slow cooker recipe, you will need

  • Sirloin Tip Roast – Also known as a round tip roast, this can be found at most grocery stores.
  • Diced Onion – Use white or yellow onion for this recipe.
  • Better than Bouillon Beef Base – We are going to use this to make our own ultra-concentrated beef broth. I absolutely love this stuff! It’s so convenient for recipes where I just need a small amount of broth. It also has great ingredients.
  • Worcestershire Sauce – This adds some rich flavor to our beef juices, but if you don’t have it on hand, you could leave it out or use soy sauce.
  • Garlic – I minced about 1 tbsp fresh garlic, but jarred garlic works great, too.
  • Dried Herbs & Spices – Dried Parsley, Salt, Black Pepper, Onion Powder, and a bit of Cinnamon

Fall Apart Sirloin Tip Roast Instructions

​Now here are the instructions for how to cook fall apart sirloin tip roast so that is perfect every time!

1. Sear Meat

Heat a medium to large size skillet to medium-high heat on the stovetop. Add a splash of olive oil to the pan. Use tongs to set your roast down on the skillet and let it cook for about 1-2 minutes per side. Use the tongs to gently rotate the roast so that you are able to brown all sides and angles of the meat. Once all of the sides are browned, set the roast aside.

2. Cook Diced Onion

Add another splash of olive oil to the skillet if needed, and then add your diced onion. Cook the onions until they soak up all of the meat flavor from the pan and are soft and fragrant.

3. Fill Slow Cooker

Add your roast and sauteed onions to the crockpot. Add 1 tablespoon of Better than Bouillon beef base to one cup of water and whisk to combine. Pour into the crock pot. Add your Worcestershire sauce, minced garlic, and all of your seasonings to the slow cooker.

4. Cook on Low

Set your crockpot to low for 8-10 hours cooking time. The timing may vary depending on your crockpot. Slow cookers that run on the hotter side will be done in 8 hours, but if yours runs cooler, then you may need up to 10 hours. See the Tips section below for more information on this.

When the meat is done cooking, use tongs to place the roast on a cutting board for you to pull apart. You will know your meat is done if it easily falls apart. The internal temperature will be at least 180-190 degrees F–while beef will be safely cooked long before that temperature, this is the temperature at which tougher cuts of beef will start to fall apart.

Shred your beef and then add it back to the cooking liquid to soak up all of the flavor and keep warm until you’re ready to serve.

Tips for Perfect Crock Pot Sirloin Tip Roast

Sirloin tip roast is very tough until it’s not. That means if you poke at it too early, you may get concerned that your meat is still too tough. It really needs the full 8-10 hours on low to tenderize. If it’s 7.5 hours into the cooking time and still tough, just let it keep going. It will eventually fall apart.

Different crockpots have different temperatures for their low setting, so the cook times may vary. When I make this in my Crockpot brand crockpot, which runs pretty hot even on low, it’s done in 8 hours. My Ninja slow cooker, however, needs much more than 8 hours on low to give me a fall-apart tender roast. If your crock pot runs on the cooler side, for best results get this meat in the crock pot early so you have plenty of time to let it tenderize.

If you want to serve this for a special occasion, it would be delicious alongside some mashed potatoes with some orangey spiced Brussels sprouts.
