Roast Chicken with Creme Fraiche

Ingredients:
4 1/2 pound whole chicken
salt and pepper to taste
1 lemon
1 bunch fresh thyme
1 bay leaf
3 cloves garlic (original recipe calls for adding a few cloves of garlic in the cavity with the herbs and lemon – I didn’t, since I had included garlic in the last twelve things I’d eaten, and was taking a break, but feel free to add!)
olive oil, as needed
3 thick slices day-old French bread (I used sourdough)

For creme fraiche glaze:
1 cup creme fraiche
1 zest of one lemon
juice of one lemon
1 tablespoon grated shallot puree
1 teaspoon Aleppo pepper
