Preparation Phase & Tools to Use

To make the best creamy roasted garlic tomato soup, preparation is key. Start by gathering essential tools:

• Baking Sheet: For roasting tomatoes and garlic—this step is critical to deepen the flavors.
• Blender or Immersion Blender: To achieve that creamy, smooth texture.
• Heavy-Bottomed Pot: Ideal for simmering the soup evenly without burning.
• Knife & Cutting Board: Basic tools for prepping the vegetables.
• Aluminum Foil: Great for wrapping garlic bulbs to roast them without burning.

Each tool plays a key role in layering the flavors and textures that define this dish.

Preparation Tips

Roasting is the soul of this soup—don’t rush it. Let the tomatoes blister and caramelize slightly in the oven, and roast the garlic until it’s golden and spreadable. Use ripe, in-season tomatoes if possible for maximum flavor, or opt for high-quality canned San Marzano if fresh ones are out of season. When blending, take care if you’re using a regular blender—let the mixture cool slightly before processing to avoid pressure buildup. Finish with a good splash of cream, fresh herbs, and season with confidence. A drizzle of olive oil or a sprinkle of chili flakes before serving adds that final gourmet touch.

Ingredients for this Creamy Roasted Garlic Tomato Soup

• 2 lbs ripe Roma tomatoes (or use canned San Marzano)
• 1 whole garlic bulb
• 1 medium yellow onion, chopped
• 2 tbsp olive oil (plus more for drizzling)
• 1 tsp sea salt
• 1/2 tsp black pepper
• 1/2 tsp red chili flakes (optional)
• 1/2 tsp dried oregano
• 1/2 tsp dried thyme or a few fresh sprigs
• 1 cup vegetable broth (or chicken broth for richer flavor)
• 1/2 cup heavy cream (or full-fat coconut milk for dairy-free)
• Fresh basil or thyme leaves for garnish

Step 1: Roast the Tomatoes and Garlic

Preheat your oven to 400°F (200°C). Cut the tomatoes in halves and arrange them on a baking sheet lined with parchment paper. Slice the top off the garlic bulb, drizzle it with olive oil, wrap it in foil, and place it on the tray with the tomatoes. Roast for 35-40 minutes, until the tomatoes are soft and slightly charred and the garlic is golden and tender.

---

Step 2: Sauté the Onion and Herbs

While the tomatoes are roasting, heat 1 tbsp of olive oil in a heavy-bottomed pot over medium heat. Add chopped onions and cook for about 5-7 minutes until translucent and slightly caramelized. Add the oregano, thyme, and chili flakes, and stir for another minute to toast the spices.

Step 3: Blend Everything Together

Once the tomatoes and garlic are roasted, remove the garlic from the foil and squeeze out the soft cloves. Transfer the roasted tomatoes and garlic into a blender along with the cooked onions and herbs. Add the broth and blend until smooth. Alternatively, use an immersion blender directly in the pot.

---

Step 4: Simmer and Add Cream

Pour the blended mixture back into the pot. Simmer on low heat for 10-15 minutes to allow flavors to develop. Stir in the heavy cream, and season with salt and pepper to taste. Adjust consistency with extra broth if needed.

Step 5: Serve and Garnish

Ladle the soup into bowls. Garnish with a swirl of cream, fresh basil or thyme leaves, and a light drizzle of olive oil. For extra richness, top with roasted cherry tomatoes or crunchy croutons.

Notes

The flavors of this soup deepen beautifully the next day, making it a great candidate for meal prep. For a vegan version, simply swap the heavy cream with full-fat coconut milk or any creamy plant-based alternative. If you prefer a chunkier texture, reserve a portion of the roasted tomatoes to stir in after blending. This soup also pairs wonderfully with crusty bread, grilled cheese sandwiches, or even a drizzle of pesto.

Watch Out for These Mistakes While Cooking

• Skipping the roasting step: This is crucial to bring out the full depth of flavor in the tomatoes and garlic.
• Blending too soon: Allow the roasted ingredients to cool slightly before blending, especially if using a traditional blender to prevent accidents.
• Under-seasoning: Taste as you go. Tomatoes can be acidic, and the soup needs enough salt and herbs to balance that out.
• Adding cream too early: Stir it in after simmering to prevent curdling.
• Using low-quality tomatoes: This soup thrives on the quality of your produce or canned tomatoes—go for ripe, in-season options or San Marzano for the best results.

Storage Instructions

Store the soup in an airtight container in the refrigerator for up to 4 days. It can also be frozen for up to 3 months—let it cool completely before transferring to freezer-safe containers. Thaw overnight in the fridge and reheat gently on the stove, stirring occasionally. Avoid boiling once the cream is added to maintain the smooth texture.
