  • 2 lbs sirloin tip steaks see NOTES
  • 2 cloves garlic minced
  • 1/4 cup chopped onion
  • 8 oz fresh mushrooms cut in half
  • 2 tbsp oil


  • 1/2 cup soy sauce I used low-sodium
  • 1/4 cup brown sugar
  • 2 tbsp dry wine white or red


  • 3 tbsp cornstarch
  • 1/4 cup water


  • Heat 1 tbs of oil in a large heavy skillet. Brown steaks on each side. Place in a 4-6 quart slow cooker.
  • Add the remaining 1 tbs of oil to the same skillet and saute the onion, garlic and mushrooms for about 5 minutes over medium heat.
  • Mix all the sauce ingredients in a small bowl and add to the skillet with the onions, garlic and mushrooms, scraping up all the browned bits from the bottom of the pan (called deglazing).
  • Pour entire contents of the pan into the slow cooker.
  • Cover and cook on low 6-8 hours, high 4-6 hours (see NOTES)
  • Remove meat from the slow cooker and turn to high (if you cooked on low heat)
  • Mix the cornstarch and water and whisk into pan juices. Cook for 15 minutes.
  • Add meat back to the crock pot and coat with the sauce.
  • Serve over rice, mashed potatoes or noodles


Sirloin tip steaks are generally large. I cut each one I used into 4 serving-sized pieces before cooking.
All slow cookers cook differently, so checking for doneness at minimum cook times is suggested. I cooked this in my Ninja 4-in-1 and a Ninja cooks a bit faster than a traditional slow cooker--mine was done in 5 hours set on low (slow cooker setting)
