Choosing the Right Tomatoes
Best Tomatoes for Soup
Roma or plum tomatoes work best in this recipe due to their meaty texture and lower water content. They roast beautifully and provide a concentrated tomato flavor. In summer, vine-ripened heirloom tomatoes add exceptional flavor, while in winter, high-quality canned San Marzano tomatoes make an excellent substitute.
Buying Tips
Look for tomatoes that feel heavy for their size with tight, shiny skin and a deep red color. They should yield slightly to gentle pressure and have a noticeable tomato fragrance at the stem end. Avoid tomatoes with bruises, soft spots, or cracks.
Substitutions
If fresh tomatoes aren’t available, substitute two 28-oz cans of whole peeled tomatoes (preferably San Marzano). For a different flavor profile, you can replace up to half the tomatoes with roasted red peppers for a sweet-smoky undertone.
Ingredients & Prep
Tomato Prep Essentials
- 3 lbs ripe Roma tomatoes (about 12-15 tomatoes)
- Core tomatoes and cut in half lengthwise
- No need to peel—the skins add flavor and will be blended smooth later
- Arrange cut-side up on baking sheets for roasting
Flavor Base Components
- 1 tablespoon olive oil (reduced from traditional 3-4 tablespoons)
- 1 medium onion, diced
- 2 carrots, finely chopped (adds natural sweetness without sugar)
- 3 garlic cloves, minced
- 1 tablespoon tomato paste (intensifies tomato flavor)
- 1 teaspoon dried basil (or 1 tablespoon fresh)
- 1/2 teaspoon dried oregano
- 1/4 teaspoon red pepper flakes (optional)
Lightened-Up Creaminess
- 1/4 cup 2% Greek yogurt (replaces heavy cream)
- 3 cups low-sodium vegetable broth (instead of cream-based stock)
- 1/4 cup grated Parmesan cheese (adds richness with less fat)
- 1 tablespoon honey or maple syrup (enhances natural tomato sweetness)
Step-by-Step Cooking Instructions
Roasting the Tomatoes
- Preheat oven to 400°F (205°C)
- Line two baking sheets with parchment paper
- Arrange halved tomatoes cut-side up on sheets
- Drizzle with 2 teaspoons olive oil and sprinkle with salt and pepper
- Roast for 30-35 minutes until edges are caramelized and tomatoes are soft

Creating the Soup Base
- Heat remaining 1 teaspoon olive oil in a large pot over medium heat

- Pour in vegetable broth and bring to a gentle simmer

Finishing the Soup
- Remove pot from heat and let cool slightly

- Return soup to low heat and stir in Greek yogurt and Parmesan cheese
- Taste and adjust seasoning with salt, pepper, and honey as needed
- Heat through but do not boil (to prevent yogurt from curdling)
Serving

- Garnish with a small dollop of Greek yogurt, fresh basil leaves, and a sprinkle of Parmesan
- Serve immediately for best flavor and texture
Pro Tips for Perfect Tomato Soup
Achieving Ideal Texture
- For ultra-smooth soup, pass through a fine-mesh strainer after blending
- If soup is too thick, thin with additional broth or water
- If soup is too thin, simmer uncovered for 5-10 minutes to reduce
- Add yogurt off the heat to prevent curdling
Tool Recommendations
- An immersion blender creates less mess than transferring hot soup to a blender
- A heavy-bottomed Dutch oven or soup pot ensures even heating without scorching
- Wooden spoons won’t scratch your cookware and are perfect for stirring soup
- A microplane grater makes quick work of fresh Parmesan
Storage & Reheating
- Store cooled soup in airtight containers in the refrigerator for up to 4 days
- Freeze in individual portions for up to 3 months in freezer-safe containers
- When reheating, warm gently over medium-low heat, stirring occasionally
- Add a splash of broth if soup has thickened during storage
- Stir in fresh Greek yogurt after reheating, not before
Flavor Variations
Roasted Garlic Version
Roast a whole head of garlic alongside the tomatoes until soft and caramelized. Squeeze the roasted cloves into the soup before blending for a mellow, sweet garlic flavor that complements the tomatoes beautifully.
Vegan Option
Replace Greek yogurt with coconut cream or cashew cream (blend 1/2 cup soaked cashews with 1/4 cup water until smooth). Use nutritional yeast instead of Parmesan cheese for a similar umami quality.
Herb-Infused Variations
- Italian: Add 1 teaspoon Italian seasoning and a Parmesan rind while simmering
- Provençal: Include 1/2 teaspoon herbes de Provence and finish with a drizzle of olive oil
- Garden Fresh: Stir in 1/4 cup chopped fresh herbs (basil, parsley, chives) just before serving
Serving Suggestions
This Classic Tomato Soup (Lightened Up!) pairs beautifully with:
- A small grilled cheese sandwich made with whole grain bread and reduced-fat cheese

For beverage pairings, try:

- Unsweetened iced tea with fresh mint
FAQs
Can I use canned tomatoes?
Yes! Use two 28-oz cans of whole peeled tomatoes. Drain (reserving juice) and roast as directed, adding reserved juice back when blending. San Marzano tomatoes provide the best flavor for this substitution.
How do I fix soup that’s too acidic?
Add 1/4 teaspoon of baking soda to neutralize acidity, or add an additional tablespoon of honey or maple syrup. The carrots in this recipe also naturally balance acidity.

Can I make this soup in a slow cooker?
Yes! Roast the tomatoes as directed, then combine all ingredients except Greek yogurt and Parmesan in a slow cooker. Cook on low for 4-6 hours, blend, then stir in yogurt and cheese before serving.
