Million Dollar Chicken on the Big Green Egg 

This is a recipe for The Standard Grill's Million Dollar Chicken adapted for the Big Green Egg.
Ingredients:
1 (4.5 pound) whole chicken
salt and black pepper
1 lemon, halved
3 cloves garlic, peeled
1 bunch fresh thyme
1 bay leaf
2 tablespoons olive oil
3 thick slices day-old sourdough
1 tablespoon olive oil
1 cup creme fraiche
1 tablespoon peeled and grated shallot
1 teaspoon Harissa
lemon juice
1 teaspoon lemon zest
Directions:
Mix crème fraiche, grated shallot, and Harissa together in a small bowl. Stir 2 tablespoons lemon juice and lemon zest into sauce. Refrigerate until needed.Preheat Big Green Egg to 450°
Season inside of the chicken with salt and black pepper. Squeeze lemon halves into the chicken cavity and drop squeezed peels inside. Stuff cavity with garlic cloves and fresh thyme; add a bay leaf to cavity.
Drizzle 1 tablespoon olive oil into a heavy roasting pan. Place sourdough slices into pan and press slices lightly into olive oil to help coat bottom of bread. Drizzle 1 more tablespoon olive oil on top of bread slices. Place chicken on top of bread slices and tie legs together with kitchen twine. Brush outside of chicken with 1 tablespoon olive oil and season entire outside with salt.
Bake chicken in the Big Green Egg for 1 hour.
Lift chicken off bread slices and flip the bread slices over (they will be very brown). Place chicken back onto the bread slices. Generously brush the outside of the chicken with creme fraiche sauce, putting enough on to drip down onto bread slices.
Return chicken to the Big Green Egg and cook for 10 more minutes to brown the glaze. Repeat, brushing more creme fraiche sauce generously onto the chicken. Cook 10 more minutes. Remove chicken from the Big Green Egg and let stand for 10 minutes. An instant-read meat thermometer inserted into the thickest part of a thigh, not touching bone, should read 165°
Pour remaining creme fraiche glaze into a small skillet, place over medium heat, and bring to a boil. Stir constantly, cooking until the shallot is cooked and sauce reduces slightly, 1 or 2 minutes. Turn off heat.
Transfer chicken to a cutting board and cut bread pieces in half crosswise. Cut chicken up into 8 serving pieces (drumsticks, thighs, wings, and breasts) and serve with pieces of drippings-soaked toasted bread. Drizzle thickened creme fraiche sauce over chicken.
Serve with Arugula Salad.
