Add the beef to a medium bowl with the flour and seasoned salt. Stir to coat.
Heat the olive oil in a large skillet over medium high heat. Add the coated beef and cook until browned, stirring as needed. There is no need to cook the beef through.
Place meat in slow cooker.
Peel and dice the potatoes, carrots, and onion. Mince the garlic. Add to the slow cooker with the bay leaf.
Sprinkle the pepper on top and pour the broth, tomato paste, and Worcestershire sauce into the slow cooker. Stir to combine.
Cook on low for 8-10 hours or high for 4-6 hours, until the beef and vegetables are tender. Every slow cooker is different and some run hotter than others so cook time does vary a bit, but stew is very forgiving.
Remove the bay leaf, add the peas to the slow cooker, and stir well. Taste and add salt and pepper as needed before serving.
