Instructions

Preheat oven to 400 degrees F. Line a large baking sheet with parchment paper. Place halved tomatoes and garlic cloves on the baking sheet and drizzle with 3 tablespoons of olive oil. Generously season with salt and pepper. Roast in the oven for 40-45 minutes.
While the tomatoes are roasting, you can make the caramelized onions: Add 1/2 tablespoon olive oil to a large pot and place over medium heat. Add the onion slices and stir to coat the onions with olive oil. Cook, stirring occasionally. Check onions every 5-10 minutes until they have completely caramelized and turned golden in color. This ususally takes 20 minutes.
Once tomatoes and garlic are done roasting, allow them to cool for 10 minutes, then add them to a food processor or high powered blender and blend until smooth. Next add basil and caramelized onions and blend again. Alternatively you can add the tomatoes to the large pot and use an immersion blender. It's really just about what you have available to you.
After blending, transfer back to pot, turn to medium low heat and add in oregano, vegetarian broth and salt and pepper to taste. From there you can add in any additional add-ons you want (as listed in the ingredients). Allow tomato soup to simmer 10 minutes before serving. To serve, garnish with parmesan cheese and serve with grilled cheese, if desired. Serves 4.

Notes

I do not usually strain the seeds, but you can with a fine mesh strainer if that's what you prefer.
Store it: store any leftover tomato basil soup in an airtight container in the fridge for up to 4-5 days. Reheat it back on the stovetop or in the microwave.
Freeze it: add the leftover soup to a freezer-friendly, airtight container and place it in the freezer for up to 3 months. To reheat, let the sauce thaw in the fridge before heating it through on the stovetop or in the microwave.
