Ingredients
Method
- Heat olive oil in a large soup pot over medium heat. Add the shallot and cook until soft, about 5 minutes. Mix in the tomato paste, garlic, and crushed red pepper, and cook for about 1 minute until fragrant.
- Add the canned tomatoes with their juices, white beans, vegetable broth, and a heaping half-teaspoon of salt. Cover and simmer over low heat for about 20 minutes to let the flavors meld.
- Add the basil, parmesan, butter, and balsamic vinegar. Puree the soup using an immersion blender, or work in batches with a standard blender or food processor until completely smooth. When using a blender, cover the lid with a dish towel and avoid sealing it tightly to let steam escape.
- Add more salt and pepper to taste.
Notes
Ingredient Swap: I love using a can of cannellini beans for their creamy texture, but I've also had great success with great northern beans when that's what I have in my pantry.
Storage Tip: This soup keeps beautifully in the fridge for up to four days.
I find the flavors actually deepen overnight, making it a fantastic make-ahead lunch.
Blender Caution: When pureeing hot soup in a blender, I always remove the center cap from the lid and cover the opening with a folded kitchen towel.
This lets the steam escape safely and prevents a messy, dangerous explosion.
Serving Suggestion: My favorite way to serve this is with a final swirl of good olive oil and a few extra torn basil leaves on top.
A grilled cheese sandwich on the side is the perfect companion.
Equipment Note: While I use an immersion blender for easy cleanup, a standard blender will give you the absolute smoothest, silkiest texture.
Just be patient and blend in batches if needed.
Flavor Secret: Don't skip the balsamic vinegar at the end.
It's my secret weapon.
It doesn't make the soup taste like vinegar, but it adds a subtle sweetness and complexity that really makes the tomatoes sing.
Common Mistake: Rushing the initial step of cooking the shallot.
Giving it a full five minutes to soften and sweeten is crucial for building the soup's foundational flavor.
