Best Creamy Roasted Garlic Tomato Soup is everything you want on a chilly day—a smooth, comforting soup with the rich flavors of slow-roasted garlic and fresh tomatoes. The garlic adds a deep, mellow sweetness that pairs perfectly with the creamy tomato base, making each spoonful a little hug in a bowl.
I love how this soup feels special even though it’s simple to make. Roasting the garlic brings out its natural sweetness without any sharp bite, which really changes the whole flavor and makes the soup so soothing. I often make a big batch and save leftovers because it tastes even better the next day.
My favorite way to enjoy this soup is with a side of crusty bread for dipping or a grilled cheese sandwich for a classic combo. It’s a great meal for when I want something cozy but don’t want to spend forever in the kitchen. Plus, it always gets compliments, so I know I’m sharing something special with my friends and family.
Key Ingredients & Substitutions
Roasted Garlic: Roasting garlic softens its sharpness and brings out a sweet, mellow flavor that sets this soup apart. If you’re short on time, you can use garlic powder, but fresh roasted is best for depth of flavor.
Tomatoes: Roma or vine-ripened tomatoes work great here because they’re juicy and flavorful. If fresh tomatoes aren’t in season, canned whole tomatoes are a good backup—just drain some juice to keep it thick.
Heavy Cream: This adds rich creaminess to the soup. For a dairy-free option, coconut milk is my favorite substitute because it’s smooth and complements tomato well without overpowering the soup.
Herbs: Thyme and sage bring earthiness and a fresh smell. Use fresh if you can, but dried thyme works fine if that’s what you have on hand.
How Do You Perfectly Roast Garlic for This Soup?
Roasted garlic is the heart of this soup’s flavor, so it deserves your attention. Here’s how I do it:
- Slice the tops off garlic heads to expose the cloves. This lets the garlic caramelize inside the foil wrap.
- Drizzle olive oil generously over the garlic. This keeps it moist and helps with roasting.
- Wrap the garlic heads tightly in foil and roast in a 400°F oven for about 35-40 minutes. You want the cloves soft and golden, not burnt.
- Once cool, simply squeeze out the soft garlic pulp. It will mash easily and blend smoothly into your soup.
Taking your time roasting guarantees a sweet, mellow garlic flavor without bitterness. It’s what makes this soup special!
Equipment You’ll Need
- Baking sheet – for roasting the garlic and vegetables; I like it because it holds everything evenly and makes cleanup easy.
- Foil – to wrap the garlic heads for roasting, keeping in the moisture and caramelizing the garlic perfectly.
- Large pot or Dutch oven – perfect for simmering the soup and blending all the flavors together.
- Immersion blender or regular blender – for pureeing the soup until smooth; an immersion blender makes it quick and easy right in the pot.
- Measuring cups and spoons – to keep your ingredients just right.
Flavor Variations & Add-Ins
- Cheese boost: Stir in grated Parmesan or mozzarella for extra richness after blending.
- Spicy kick: Add a pinch of crushed red pepper flakes during cooking for some heat.
- Herb twist: Use fresh basil or parsley as a garnish or stirred in for a fresh, vibrant flavor.
- Veggie add-ins: Mix in cooked spinach, zucchini, or roasted red peppers for more texture and flavor variations.

How Much Time Will You Need?
This recipe takes about 10 minutes to prep, 35-40 minutes to roast the garlic, and about 30 minutes to roast the vegetables, simmer, and blend the soup. Overall, you’ll spend roughly 1 hour from start to finish, including gentle reheating after adding cream.
Step-by-Step Instructions:
1. Roast the Garlic:
Preheat your oven to 400°F (200°C). Cut the tops off the garlic heads to expose the cloves. Drizzle with 1 tablespoon olive oil and wrap each head tightly in foil. Roast in the oven for 35-40 minutes until garlic is soft and caramelized.
2. Roast the Vegetables:
While the garlic roasts, place the quartered tomatoes, chopped onion, and carrot on a rimmed baking sheet. Drizzle with the remaining 1 tablespoon olive oil, sprinkle with thyme, salt, and pepper. Roast for 25-30 minutes until the vegetables are tender and slightly caramelized.
3. Prepare the Soup Base:
Once the garlic is cool enough to handle, squeeze out the soft, roasted cloves into a large pot. Add the roasted tomatoes, onion, and carrot to the pot.
4. Simmer the Soup:
Pour in the broth and bring the mixture to a simmer over medium heat. Let it cook gently for about 10 minutes so the flavors blend beautifully together.
5. Blend Until Smooth and Creamy:
Use an immersion blender directly in the pot or carefully transfer the soup in batches to a blender. Puree until silky smooth and creamy.
6. Add Cream and Seasonings:
Stir in the heavy cream and sugar (if using), then season with salt and freshly ground black pepper to taste. Reheat gently if needed, but avoid boiling once the cream is added to keep it creamy.
7. Serve and Enjoy:
Ladle the hot soup into bowls. Garnish with fresh sage or thyme leaves and a swirl of cream if you like. Serve with toasted crusty bread on the side for dipping and soak up every delicious spoonful!
Can I Use Canned Tomatoes Instead of Fresh?
Absolutely! Use a 28-ounce can of whole peeled tomatoes as a convenient substitute. Drain some of the juice to keep the soup from being too watery, and roast or sauté with the onion and carrot before blending.
How Should I Store Leftover Soup?
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently on the stove or in the microwave, stirring occasionally to keep the texture smooth. You can also freeze it for up to 3 months.
Can I Make This Soup Dairy-Free?
Yes! Swap the heavy cream with full-fat coconut milk or another plant-based cream alternative. It still adds great creaminess without changing the soup’s flavor too much.
How Do I Get a Smoother Texture?
Using an immersion blender directly in the pot works well, but for an ultra-smooth finish, blend in small batches in a regular blender. Passing the soup through a fine mesh sieve after blending can make it extra velvety.
