How to Make It
To prepare stew, heat a large Dutch oven coated with cooking spray over medium-high heat. Add beef; cook 6 minutes, browning on all sides. Remove from pan.
Add 2 cups fennel bulb, bell pepper, onion, and garlic to pan; reduce heat to medium, and cook for 10 minutes, stirring occasionally. Add beef, carrot, and next 9 ingredients (carrot through broth). Cover, reduce heat to low, and simmer 1 hour, stirring occasionally. Add parsnip; cover and simmer 30 minutes or until beef is tender, stirring occasionally.
To prepare gremolata, combine 1/2 cup fennel bulb, fennel fronds, and grated orange rind in a small bowl.
Spoon 1 1/3 cups stew into each of 6 bowls; top each with 1 1/2 tablespoons gremolata.
