Tomato Soup with Parmesan Croutons

In a large pot, heat butter and oil over medium-high heat, then add onion, garlic, and carrots. Stir and cook for 5 minutes. Add tomato paste and stir it in, cooking for another 2-3 minutes. Add canned tomatoes with their juice, broth, and water. Stir together and bring to a boil, then reduce the heat, cover the pot, and simmer for 15-20 minutes, longer if you have time. Use an immersion blender to puree, still leaving some texture to the tomatoes. Add cream, salt, pepper, parsley, and basil, and simmer for another 5 minutes. To make the croutons, drizzle crostini rounds lightly with olive oil. Place little piles of Parmesan in a nonstick skillet. Place a crostini round on top of each pile. Turn on the heat to medium. Press with a spatula as you melt the cheese into each round. When set, flip to the other side to toast. Serve soup with one or two croutons on top and a little bit of basil. NOTE: Recipe can easily be halved!
