Ingredients

Instructions

  1. Step 1: Heat a large Dutch oven over medium heat and add 4 oz diced guanciale; cook for 5 minutes until crisp and golden, stirring occasionally. Add 1 medium finely diced yellow onion, 1 medium finely diced carrot, and 2 finely diced celery stalks; sauté for 8 minutes until vegetables are soft and translucent.
  2. Step 2: Add 1.5 lbs diced beef chuck roast and sear for 4 minutes per side until browned. Pour in 1 cup red wine, scraping up browned bits, and simmer until wine reduces by half, about 3 minutes.
  3. Step 3: Stir in 28 oz crushed San Marzano tomatoes, 2 cups beef stock, 2 sprigs fresh rosemary, 1 tsp chopped fresh thyme, 1 tsp salt, and 1/2 tsp black pepper. Bring to a gentle simmer, then reduce heat to low, cover, and cook for 2.5 hours until beef is fork-tender.
  4. Step 4: Remove rosemary sprigs, discard, and adjust seasoning. Simmer uncovered for 15 minutes to thicken sauce to a spoon-coating consistency.
