In a medium saucepan over medium heat, add butter, basmati and orzo. Stir well and sauté until the rice turns brown, about 7 minutes, stirring often. To this add, red onions, celery and pressed garlic; sauté for 2 minutes, stirring constantly.
Pour in chicken broth and season with Herbes de Provence, basil, cayenne pepper, sea salt, freshly ground black pepper and parsley. Bring the mixture to a boil, cover and reduce the heat to low. Simmer for 15 to 17 minutes or until the liquid is absorbed.
Remove from the heat and fluff rice with a fork. Cover and let it sit for 5 minutes before serving. Makes 4 servings.
