Ingredients

1. 4 tablespoons unsalted butter
2. 1 1/2 pounds medium carrots
3. 1 medium onion, halved lengthwise and thinly sliced crosswise
4. 1 celery rib, finely chopped
5. 1 garlic clove, smashed
6. 1/2 pound tomatoes—peeled, seeded and chopped
7. Bouquet garni made with 6 parsley sprigs, 3 thyme sprigs and 1 bay leaf, tied with kitchen string
8. One 1/2-inch-thick orange slice, halved
9. Sea salt and freshly ground pepper
10. 1 tablespoon coarsely chopped flat-leaf parsley

1. Melt the butter in a large skillet. Add the carrots and cook over moderate heat, turning frequently, until lightly browned, about 15 minutes. Transfer the carrots to a plate.
2. Add the onion, celery and garlic to the skillet and cook over moderate heat for 3 minutes. Add the tomatoes, bouquet garni and orange slice, season with salt and pepper and cook for 2 minutes. Nestle the carrots in the sauce. Cover and cook over low heat, turning the carrots occasionally, until meltingly tender but not falling apart, about 1 hour. Discard the bouquet garni. Sprinkle the carrots with parsley and serve warm or at room temperature.
