Teriyaki-Portobello Pork Loin

My family loves my teriyaki pork roast and begs for more! The slow cooker does most of the work, and when I get home from school the whole house smells wonderful. Since I serve it with instant rice and frozen vegetables, I'm only five minutes from sitting down to a home-cooked meal.—Lori Harris, Montgomery City, Missouri
  • Total Time
    Prep: 25 min. Cook: 6 hours
  • Makes
    8 servings


  • 1 boneless pork loin roast (3 to 4 pounds)
  • 1/2 cup all-purpose flour
  • 1 teaspoon Montreal steak seasoning
  • 2 tablespoons olive oil, divided
  • 2 cups sliced baby portobello mushrooms
  • 1 medium onion, thinly sliced
  • 1 cup water
  • 1 cup reduced-sodium teriyaki sauce
  • 1 envelope (3/4 ounce) mushroom gravy mix
  • 2 tablespoons cornstarch
  • 2 tablespoons cold water
  • Hot cooked rice
  • Chopped chives, optional


  • Cut roast in half. In a large shallow dish, combine flour and steak seasoning. Add pork, 1 portion at a time, and turn to coat.
  • In a large skillet, brown roast in 1 tablespoon oil on all sides. Transfer meat and drippings to a 4-qt slow cooker. In the same skillet, saute mushrooms and onion in remaining oil until tender; add to slow cooker.
  • In a small bowl, combine the water, teriyaki sauce and gravy mix; pour over pork. Cover and cook on low for 6-8 hours or until pork is tender.
  • Remove pork to a serving platter and keep warm. Skim fat from cooking juices; transfer to a large saucepan. Bring liquid to a boil. Combine cornstarch and cold water until smooth; gradually stir into the pan. Bring to a boil; cook and stir for 2 minutes or until thickened. Serve with pork and rice. If desired, top with chopped chives.

    Way to much teriyaki sauce. I only used a half cup and it was still way too much. I ended up washing the meat off and just used plain gravy for it.
