01 - Thoroughly pat the beef chuck cubes dry with paper towels, then season generously with salt and black pepper.
02 - If desired for a richer flavor, heat a large skillet over medium-high heat and brown the seasoned beef cubes in batches until seared on all sides. Transfer the browned beef to a 5–6 quart slow cooker.
03 - Add the prepared carrots, potatoes, celery, chopped onion, and minced garlic to the slow cooker with the beef.
04 - In a separate bowl, whisk together the beef broth, optional dry red wine, tomato paste, Worcestershire sauce, dried thyme, and dried rosemary. Pour this liquid mixture over the beef and vegetables in the slow cooker. Add the bay leaves.
05 - Securely cover the slow cooker and cook on the low setting for 7 to 8 hours, or on the high setting for 4 to 5 hours, until the beef is fork-tender and the vegetables are soft.
06 - Carefully remove and discard the bay leaves from the stew.
07 - In a small bowl, whisk together the cornstarch and cold water to create a smooth slurry. Stir this slurry into the hot stew along with the frozen peas. Increase the slow cooker setting to high and cook for an additional 15 to 20 minutes, or until the stew has thickened to your desired consistency and the peas are heated through.
08 - Taste the stew and adjust salt, pepper, or other seasonings as necessary before serving.
