Mix together flour, salt, pepper, and garlic powder in large plastic bag. (I usually use a big Tupperware bowl since it has enough room for the meat and then I can just wash it.) Put the roast in the bag/bowl and shake it until completely coated in flour
Preheat a large skillet to medium-high and add olive oil. Brown all sides of the roast.
Add your onion slices and carrots to the bottom of the slow cooker.
Place roast on top of onions, then pour beef broth and soup over top.
Cook 9 hours on low heat in slow cooker. Serve with mashed potatoes, veggies, and gravy.
Gravy Directions:
When the meat is fully cooked, remove the liquid from the slow cooker and place in saucepan over medium heat.
Add bouillon and stir until it’s completely mixed in to the broth.
Mix together 2 tablespoons corn starch and 1/4 cup water.
Slowly add the corn starch mixture into the broth, stirring constantly.
Simmer over medium heat for one minute. Season if needed.
