Step 4
Cook – Cover and cook on LOW for 8–9 hours or HIGH for 5–6 hours, until beef is fork-tender.
Step 5
Make Mashed Potatoes – Boil potatoes in salted water (1 tbsp kosher salt) until soft. Drain. Mash with olive oil + milk, seasoning with ½ tsp salt + ½ tsp pepper. Adjust milk for creaminess.
Step 6
Serve – Slice or shred roast, serve with carrots, celery, and a ladle of cooking liquid (remove bay leaves first). Serve alongside mashed potatoes.

[Optional] Gravy Boost – Blend 1 cup of the cooked carrots + some broth until smooth, then stir back in to make a naturally sweet, veggie-thickened gravy.
