Cut stew beef into bite size pieces and toss in flour. Heat oil in a heavy bottom skillet over medium heat. Add beef to hot oil and cook for 8 minutes, tossing frequently, to brown the outside.
Cut potatoes into quarters, peel and slice carrots into rounds, and slice celery into half moons.
Whisk beef broth, red wine, tomato paste, worcestershire sauce, salt, and pepper together.
Add browned beef and any drippings from the pan to your slow cooker along with the potatoes, carrots, celery, peas, liquid mixture and the bay leaves.
Stir to mix the ingredients and close the lid of the slow cooker. Cook on low for 10 hours OR cook on high for 5 hours. Stir occasionally while cooking if possible.
Remove bay leaves and serve with fresh cracked black pepper, freshly grated parmesan cheese and some fresh chopped parsley.
Notes
You can cook on low or on high, or use a combination of both. You will know the stew is done when the meat is fork tender.
Feel free to add extra vegetables like onions, shallots, and diced tomatoes to the stew
Serve with fresh cracked black pepper, fresh herbs, and grated parmesan cheese
If you cannot or do not want to use red wine, use 1 tbsp of red wine vinegar and an extra 1/2 cup of beef broth when combining the liquid ingredients.
