Toss tomatoes, onion, carrots & garlic with olive oil, salt & pepper in a Dutch oven. Nestle the garlic head in the center (see Note 📝 for milder garlic flavor). Roast 40 min at 400°F until caramelized.
Squeeze roasted garlic into pot, add beans, broth, and oregano. Blend until smooth.
Stir in parmesan, adjust seasoning, and serve with crusty bread.
For well-roasted garlic with a milder flavor, wrap the head in foil with olive oil and roast on the oven rack beside the pot instead of nestled within. For a more garlic-forward flavor, make as written!
Use an immersion blender for a rustic texture, or a high-speed blender for a super-smooth soup.
