Preheat oven to 425 degrees F. Halve or quarter tomatoes if you are using large ones (you can leave cherry tomatoes whole). Spread them out on a parchment-lined baking sheet along with the sliced onion and the 6 smashed cloves of garlic. Drizzle with the olive oil (2 tablespoons) and season with kosher salt (1/2 teaspoon) and pepper (1/4 teaspoon). Bake at 425 degrees F for 30 minutes (see notes).
Meanwhile, heat up chicken stock (2 cups) in a large pot on the stove.
Add roasted tomatoes/onions/garlic to the warm chicken stock, along with the entire jar of roasted red peppers. Use an immersion blender to puree the soup directly in the pot (or a standing blender in batches).
OPTIONAL: Use a mesh sieve to strain the soup into another pot or large container, using a wooden spoon to squeeze as much liquid out as possible. Discard solids left behind. This will result in a very smooth, bisque-like soup.
Stir in heavy cream (1/4 cup). Taste and season with salt and pepper, if necessary.Serve hot, garnished with croutons, fresh basil, more cream, and black pepper, if desired.
The longer you roast the tomatoes, the more flavorful they will be. You can roast them for longer at a cooler temperature. Try an hour at 375 degrees, two hours at 350 degrees, or even three hours at 300 degrees, depending on how much time you have available.
Prep ahead: you can roast the tomatoes up to 3 days in advance and store in the refrigerator in an airtight container.
Make it vegan: omit the cream, or use full-fat canned coconut milk as an alternative.
Freeze it: this soup is great to make in bulk because it freezes beautifully. Store it in an airtight container for up to 6 months in your freezer. Run hot water over the container to loosen it a bit, and pop the whole block of frozen soup into a pot to defrost directly on the stovetop when you're ready to eat it.
