Unwrap the chicken and remove the giblets and/or the neck (if included). Pat the chicken dry with paper towels. If possible, let the chicken sit at room temperature for 30-60 minutes to allow for more even cooking.
02 -
Preheat the oven to 220°C (425°F).
03 -
Season the entire chicken generously with salt and pepper. Stuff the cavity with the thyme, garlic, and lemon. Brush the outside of the chicken with the melted butter and season again with salt and pepper.
04 -
Use kitchen twine to tie the legs together. Tuck the wings underneath the body of the chicken for even cooking.
05 -
Place the sliced onions, carrots, and fennel bulb on the bottom of a roasting pan. Sprinkle the vegetables with salt, pepper, 20 sprigs of thyme, and drizzle generously with olive oil. Toss to evenly coat the vegetables.
06 -
Place the chicken on top of the vegetables. This prevents the chicken from sitting in its own juice while it cooks and elevates the chicken for even cooking.
07 -
Roast uncovered for 1½ hours. Halfway through, use a spoon to drizzle the chicken with some drippings from the bottom of the pan. Rotate the pan 180 degrees and place it back in the oven.
08 -
The chicken is done when the juices run clear and the internal temperature reads 74°C (165°F). Place a meat thermometer into the thigh to check the temperature.
09 -
Let the chicken rest, uncovered, for 15-20 minutes to allow the juices to reabsorb before carving.

Pour the chicken drippings into a large measuring cup. Top it off with chicken broth to make 475 ml (2 cups). Melt 3 tablespoons of butter in a saucepan over medium heat. Add 3 tablespoons flour and whisk for 1 minute. Add half of the gravy juice/broth and whisk until there are no lumps. Add remaining liquid and whisk for 2 minutes. The gravy will continue to thicken. Season with salt and pepper if desired.

Carve the chicken and serve with the roasted vegetables and gravy.
