Begin by putting the cloves in tin foil and drizzle with oil. Place in a 400 degree oven for 45 minutes or so. Remove from oven and open the tin foil to cool some.
Next begin heating the oil in a Dutch Oven on medium heat. Add the celery, carrots, onions and seasonings and cook for 5 minutes until softened. Next, add the tomato paste and cook for a couple of minutes. Mix well.
Squeeze the roasted garlic into the Dutch oven and cook for 2 minutes breaking up the garlic. Next, add the tomato juice and simmer for a couple of minutes. Now, add in the San Marzano tomatoes with sauce. Simmer for 15 minutes. Next, add in the Parmesan rind and simmer for another 30 minutes. Check the seasoning level.
Serve on the gnocchi and enjoy!
