Set your oven to 350°F (175°C).
In a baking dish, add cherry tomatoes, garlic cloves, olive oil, fresh rosemary, chili pepper flakes, and salt & pepper. Mix well.
Bake in the oven for 20-30 minutes, until the tomatoes are softened and slightly caramelized.
Remove the rosemary sprigs, then mash the garlic and tomatoes together in the baking dish. Add the cannellini beans and bake for an additional 10 minutes. Add a little more olive oil if the mixture seems dry.
Take the dish out of the oven, top with crème fraîche, and serve with toasted ciabatta bread brushed with melted butter and sprinkled with Italian seasoning.
