Instructions

Prep and Season Roast:

Add Vegetables:
Arrange onion, garlic, carrots, and celery around the roast in the slow cooker.

In a bowl, whisk together beef broth, tomato paste, Worcestershire sauce, thyme, rosemary, and bay leaves. Pour over the roast and vegetables.

Drain well and return potatoes to the pot. Add butter and milk, mash until smooth and creamy. Season with salt and pepper. Add more milk if needed.
