Coat the inside of a slow cooker with non-stick spray. I use a 6-quart pot.
Peel and chop the sweet potatoes into large chunks. Measure to get a heaping 3 cups and place in the prepared slow cooker.
Add in the chopped celery, chopped onion, the bag of carrots, drained can of corn (I buy corn that is fire-roasted and it adds so much flavor! It's right by regular canned corn in the grocery store) and undrained can of diced tomatoes.
Toss together the flour, seasoned salt, and pepper. Toss the cut meat (cut in 1 inch cubes if not pre-cut) in the flour mixture until well coated.
Place the coated meat in the slow cooker on top of all the vegetables. You do not need to pre-cook the meat.
Add in the bay leaf, minced garlic, paprika, Worcestershire sauce, and fresh parsley. (I coarsely chop parsley and pack it in a tablespoon to get that measurement.)
Crumble in the bouillon cubes and the water.
Stir everything together and submerge the meat below the veggies to keep it as tender as possible. Cover and cook on low for 7-9 hours, high for 5-7 hours or until the sweet potatoes and vegetables are tender and the meat is cooked through and tender. All slow cookers cook at different temperatures. Mine takes about 8 hours on low and I don't typically cook stews on high because I find them to be more flavorful (meat more tender) after slow cooking all day! If you are home, occasionally stir the stew throughout the day.
When ready to serve, remove the bay leaf.
Stir the ingredients together and slightly mash the tender sweet potatoes in the crockpot. This gives it a chunkier and thicker stew consistency and it's delicious!
If desired, top with some fresh parsley.
