Nothing feels more balanced than a bowl of roast tomato soup made from simple ingredients and honest flavor.
This recipe takes basic pantry staples—tomatoes, onion, garlic, and broth—and turns them into a smooth, satisfying meal that’s easy to prepare any night of the week.
It’s the kind of soup that pairs perfectly with toasted bread and requires no fuss to deliver deep, roasted flavor.
Why This Recipe Works
- Roasting builds depth: Cooking the tomatoes, onions, and garlic in the oven caramelizes their natural sugars and creates a rich base without extra seasoning.
- Simple ingredients, clean flavor: Each ingredient adds purpose—no fillers or complex steps, just pure tomato essence with subtle herb notes.
- Easy blending: The roasted vegetables break down quickly, creating a smooth consistency without heavy cream or butter.
- Adaptable to your taste: Works with vegetable or chicken broth, and you can make it creamy or leave it light.
- Minimal cleanup: Everything roasts on one pan, then blends into one pot, making this a go-to option for busy days.
Ingredients
- 4 medium tomatoes (about 500–700g), halved
- ½ onion, roughly chopped
- 2 cloves garlic
- 2 tbsp olive oil
- Salt and black pepper, to taste
- ½ tsp dried herbs (such as basil or thyme, optional)
- 2 cups vegetable or chicken broth
- A few fresh basil leaves for garnish
Equipment Needed
- Baking sheet
- Blender or immersion blender
- Medium pot
- Knife and cutting board
- Measuring cups and spoons
- Ladle
Instructions
Step 1: Roast the Vegetables
Preheat your oven to 400°F. Arrange the halved tomatoes, chopped onion, and garlic cloves on a baking sheet. Drizzle with olive oil and sprinkle with salt, pepper, and dried herbs if using.
Spread them out evenly for consistent roasting. Place the tray on the middle rack and roast for about 30 minutes, or until the tomatoes are soft, edges are slightly browned, and the aroma deepens.
Roasting draws out moisture and concentrates sweetness, which builds the foundation for a full-bodied soup without the need for long simmering.
Step 2: Blend to a Smooth Consistency
Transfer the roasted tomatoes, onion, and garlic into a blender. Pour in the broth, then blend until smooth. The mixture should be thick but pourable, with a vibrant orange-red color.
If you prefer a silkier texture, strain through a fine sieve or add a splash of cream. Tip: Always blend in small batches if your blender is not heat-safe to avoid pressure build-up. The smoothness of this step determines the final mouthfeel, so take a few extra seconds to ensure it’s evenly blended.
Step 3: Simmer and Adjust Seasoning
Pour the blended soup into a medium pot and warm over low heat for 5–10 minutes. Stir occasionally to prevent sticking. Taste and adjust with salt or pepper as needed.
If the soup feels too thick, add a bit more broth or water. The goal is a balanced, light consistency that feels clean and comforting.
Once it starts to bubble gently, it’s ready to serve.
Tip: For added depth, a small pinch of sugar can balance the acidity of the tomatoes.
Step 4: Serve and Garnish
Ladle the soup into bowls and top with fresh basil leaves. You can also drizzle a little olive oil or swirl in a teaspoon of cream for a refined touch.
This minimalist presentation fits both casual and elegant meals. Serve with crusty bread or a simple grilled cheese sandwich to complete the dish.
The roasted aroma and clean flavor profile make it equally suitable for lunch or a light dinner.
Tips and Tricks
Selecting the Right Tomatoes
Use ripe, medium-sized tomatoes for the best balance of acidity and sweetness. Roma or vine-ripened tomatoes work particularly well. Avoid underripe tomatoes since they yield a sharper, less rounded flavor.
Texture Control
For a thicker soup, use less broth and blend longer. For a lighter texture, add an extra ½ cup of broth or a splash of water. Straining after blending removes any pulp and gives a more polished finish.
Creamy Option
To turn this into a creamy tomato soup, stir in 2 tablespoons of heavy cream or coconut milk after blending. Heat gently without boiling to maintain smoothness.
Batch and Storage Tips
This soup keeps well. Store in an airtight container in the refrigerator for up to 3 days or freeze for up to 2 months. Reheat over medium heat and whisk gently to restore texture.
Serving Suggestions
Pair with toasted bread, grilled cheese, or a drizzle of pesto for added depth. You can also use this soup as a base for pasta sauces by reducing it slightly over heat.
Recipe Variations
- Spicy Tomato Soup: Add ½ teaspoon of red chili flakes before roasting for a gentle kick.
- Creamy Basil Version: Blend in a handful of fresh basil leaves before simmering for a herbal note.
- Roasted Red Pepper Tomato Soup: Add one roasted red bell pepper during blending for smoky sweetness.
- Garlic Lover’s Soup: Double the garlic for stronger aroma and body.
- Mediterranean Twist: Mix in a teaspoon of balsamic vinegar and top with crumbled feta before serving.
Frequently Asked Questions
Can I use canned tomatoes instead of fresh?
Yes. Use one 28-ounce can of whole or diced tomatoes, drained. Roast them briefly under the broiler for 10 minutes with onion and garlic to mimic the roasted flavor.
Is this soup suitable for vegans?
Absolutely. Use vegetable broth and skip any dairy add-ins. Olive oil and fresh herbs provide plenty of richness.
Can I make this without a blender?
Yes. Mash the roasted vegetables with a potato masher or fork, then whisk in the broth for a rustic texture. It won’t be as smooth, but it retains excellent flavor.
How do I prevent bitterness?
Sometimes tomato seeds and skins can cause slight bitterness. To avoid this, strain the blended soup through a fine sieve or use peeled tomatoes.
What side dishes go best with tomato soup?
Crusty sourdough bread, garlic toast, or grilled cheese are classic companions. For a light meal, add a simple green salad or roasted chickpeas on the side.
