Remove silver skin/sinew and excess fat from roast. Rub meat with several of the crushed cloves of garlic. Sprinkle with salt and pepper. Tie the meat into roast.
Using a long, thin knife pierce the roast several inches deep in a half-dozen evenly spaced areas. Using a teaspoon handle, push crushed garlic pieces and rosemary leaves into slits. Rub roast with olive oil.
Preheat oven 350 degrees.
Place dutch oven on stove over high heat. When pot is hot, sear roast, browning on all sides. Remove roast and reduce heat to medium. Add 1-2 Tbs olive oil. Saute carrots, celery, and onions to brown.
