Place the chicken on top of the vegetables
Add a thermometer probe into either the chicken breast or thigh
Squeeze the lemon’s juice over the chicken and add the lemon into the chicken’s cavity
Put the chicken in the oven breast first (so it faces the back) for 15 minutes
Rotate the chicken so the legs are in the back of the oven and turn the oven temperature down to 350 F
Remove the chicken from roasting when the thermometer reaches 162 F if the probe is in the breast, or 175 F if the prob is in the thigh
Place the chicken on a sheet pan or carving board to rest for 15 minutes
Check to see if the vegetables are finished cooking by piercing them with a knife or fork (if it slides in easy they should be ready); if the vegetables need more time, return them to the oven for 15 more minutes
Carve the chicken and serve with the roast vegetables and any jus from the pan
