The smooth texture of the roasted tomatoes and the distinct savory sweetness from the basil all cozied up in the rich creamy Creme Fraiche to create that perfect soup you've been craving. Pair it with some crispy grilled cheese on the side, and you have that perfect dish to get all those Fall feels.
In a soup pot or dutch oven over medium heat, add in the butter and allow the butter to melt. Once it begins to bubble toss in the onions. Saute for about 6 minutes until they are golden brown.
Add in the crushed whole cloves of garlic, crushed red pepper flakes, 1/4 tsp each of salt + pepper, and tomato paste. Scrape the paste along the bottom of the pan for about 2-3 minutes with a wooden spoon or wooden spatula until fragrant and tomato paste has turned to a deep brick red color.
Next, stir both cans of either diced or crushed (even whole if you have them) of Fire-Roasted Tomatoes along with the juices in the can. Stir in the grated Pecorino Romano cheese or Parmesan cheese if you prefer, fresh basil leaves, and bring to a boil.
Once it begins to boil, turn the heat down to low and simmer, occasionally stirring, for about 25-30 minutes to break down the tomatoes and allow the mixture to thicken.
Once it's simmered and has thickened some, allow it to cool for a couple of minutes. Using a blender or immersion blender puree the soup. Depending on what you use to blend the tomato soup mixture along with how large of a quantity you can blend at a time will vary on how long this process will take.
Once your soup is well blended and smooth, transfer it to a large serving bowl and drizzle 1/2 cup of creme fraiche (or sour cream if you prefer) over the top, and swirl it around to mix it in with the soup. Serve warm with some crispy bread or a grilled cheese sandwich.
Notes
Salty Tip:
When you cook with tomato paste, you want to add it before any liquid ingredients. You want it to release its flavors as you cook it so the flavors can meld with the other ingredients in your dish. It will turn from that bright red to a deep brick red color.
If the tomato mix is too acidic for your liking, you can neutralize it some with 1/2 tsp baking soda which helps to raise the pH level of the tomatoes. Just wait until after you add the baking soda to salt the soup as it will add some saltiness to the mix and you don't want to over-salt it.
Storage: Store any leftovers in an airtight food container and reheat in the microwave until warm throughout or heat on stove over low heat until warm throughout.
