Ingredients

Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large heavy-bottomed pot over medium-high heat until shimmering. Season 3 lbs beef chuck roast with 1 1/2 tsp sea salt and 1 tsp black pepper. Sear roast on all sides for about 3-4 minutes per side until a deep brown crust forms. Remove and set aside.
  2. Step 2: Add 1 large quartered yellow onion, 5 smashed garlic cloves, 4 medium peeled and chunked carrots, and 3 medium peeled and chunked parsnips to the pot. Sauté for 5 minutes until vegetables start to caramelize and become fragrant.
  3. Step 3: Return the seared beef to the pot, pour in 2 cups Whole30-compliant beef broth, and tuck 4 fresh thyme sprigs around the roast.
  4. Step 4: Cover the pot with a tight-fitting lid, reduce heat to low, and simmer gently for 3 hours, or until the beef is fork-tender and vegetables are soft.
  5. Step 5: Remove thyme sprigs, slice the beef, and serve with the root vegetables and some of the braising liquid spooned over.
