This recipe for Crock Pot Sirloin Tip Roast with fall-apart, tender beef and vegetables in au jus, will become your new favorite slow cooker dinner at the end of long day!
First you want to add you potatoes to the bottom of your slow cooker. Then add carrots and lay thick onion slices on top. Add small cubes of butter and no need to stir. Butter will melt enhancing the flavor of au jus.
Lay your fresh sirloin tip roast on top of vegetables. Make sure to remove the twine, if any, to give meat the chance to become tender. If you forgot, it’s OK but remember next time.
In a medium bowl, whisk together the beef broth, soy sauce, worcestershire sauce, apple cider vinegar, garlic powder, onion powder, smoked paprika, dried parsley, salt and pepper.
Slowly pour beef stock mixture on top of roast, making sure to get all the last bits that may have settled at the bottom of the bowl. Do not clean the roast or stir anything. Cover your crock pot with a lid.
A lean roast like sirloin tip roast benefits from slow cooking on low heat. I recommend to slow cook it for 8-10 hours on Low. You can absolutely cook it for 4-5 hours on High heat but it might be a bit more tough.
