Preheat oven to 350F

In a small bowl, combine the olive oil, garlic, rosemary, thyme, paprika, black pepper and salt (about 2 tbsps or to taste).

Pour the mixture on the chicken and rub it all over. Let it marinate for at least 30mins to overnight (put it in the fridge if you're leaving it overnight).

Place the chicken on a baking tray (or with a rack) and bake at 350F for 1 hour. Then increase the temp to 400F and bake for 15mins more (total of 1hr and 15mins).

For the gravy, melt the butter in a saucepan on med-low heat. Fry the mushrooms for 1min then add the four. Mix well to cook-out the flour (roux).

Add 1-1.5 cups of chicken stock depending on how thick you like your gravy. You can also use the drippings or juices from the roasting tray. Add salt and pepper to taste.
