Prepare rabbit: Cut the rabbit into 6 pieces: the hind legs, the front legs, and the back strap cut into two parts. The belly flaps and the carcass are leftover; they are great for making stock (Note 3). Dry the meat pieces with kitchen towels.
Sear meat: Heat a large shallow Dutch oven or another large heavy-bottomed pan. Add oil and butter. Fry the meat on both sides until golden, about 5 minutes per side.
Prepare vegetables: In the meantime, cut the garlic cloves into thin slices. If using fresh tomatoes, place them in a large pot and cover them with boiling water. Let stand for 1 minute, drain the water and remove the tomato peel. Chop the tomatoes into small cubes.
Add ingredients: Add the garlic to the pot and stir it for 1 minute. Pour in the white wine and let it bubble shortly. Add the chopped tomatoes, bay leaves, rosemary sprig, sage leaves, salt, and pepper to taste.
Simmer: Stir, cover the pot and simmer very gently for 30-35 minutes or until the rabbit is cooked through and tender.
Roast the pine nuts in a dry pan. Shake the pan often and don’t leave it unattended; the pine nuts can burn within seconds. Transfer to a plate immediately.
Adjust taste: Once the rabbit stew is cooked, stir in the chopped parsley and adjust the taste with salt and pepper.
Sprinkle it with pine nuts just before serving.
