Add 2 more tablespoons of avocado oil. Saute 2 cups onion, 2 cups carrots, and 2 cups celery stalks for 8 minutes with 1 tablespoon garlic powder, 1 tablespoon onion powder, and 1 tablespoon salt and 1 teaspoon cayenne pepper. Stirring often until the vegetables start to soften.
Add all of the chuck roast back to the pan and stir. Add 1 tablespoon dried rosemary, 1 teaspoon dried thyme, 8 garlic cloves, 2 tablespoon Worcestershire and stir. Let garlic cook for 30 seconds
Add 6 ounce can tomato paste and stir. Let it cook for 1-2 minutes to caramelize it a bit
Add 6 potatoes and 6 cups chicken stock to cover everything. Bring the stew to a simmer. Add 3 bay leaves and let simmer uncovered for 1 hour.
Check the tenderness of the meat and taste for seasoning. After an hour, the beef should be fork-tender. We’ll still be cooking the stew for about 30 more minutes so if it’s not tender, don’t worry. Feel free to add salt or other seasonings. If the broth is too salty for your taste you can add a cup of water, stir, and taste again.
Add 1 ½ cups frozen peas and simmer for another 20 minutes.
When the peas are tender, mix 3 tablespoons cornstarch with 3 tablespoons water to create a slurry. Slowly stir the cornstarch mixture into the stew and stir thoroughly to disperse it. Allow the stew to cook for 10 more minutes to thicken. If it isn’t thickened to your taste, you can add another tablespoon of cornstarch mixed with a tablespoon of water. Let it simmer and see if it’s thick enough.
