Instructions
Sear the beef (optional)
1
Pat cubes dry, season with salt and pepper, and sear in hot oil across two batches until a mahogany crust forms, about 2 minutes per side.
Build the sauce base
2
In the same pan, sauté onion and celery for 3 minutes over medium heat, scraping up any fond. Add garlic and tomato paste; cook 2 minutes more until the paste darkens and smells sweet.
Load the crock pot
3
Scrape the aromatics over the beef, then add carrots, potatoes, beef stock, Worcestershire, thyme, paprika, and the bay leaf. Stir once.
Slow cook
4
Cover and cook on LOW for 7 to 8 hours or HIGH for 4 to 5 hours. The beef is ready when a fork flakes it apart with no resistance, and internal temperature reads between 195°F / 90°C and 205°F / 96°C.
Thicken the gravy
5
Whisk cornstarch into cold water, then stir the slurry into the hot stew. Switch to HIGH, remove the lid, and cook 15 to 20 minutes until the sauce coats a spoon.
