Step-by-Step Cooking Instructions

This soup starts in the oven.

Pre-Cooking Prep

1. Preheat oven to 425°F.

3. Arrange tomatoes, red peppers, onion, and garlic on the sheet.

4. Drizzle with olive oil and sprinkle with salt, pepper, thyme, and smoked paprika.

Roasting Method

1. Roast for 30–35 minutes until vegetables are tender and slightly charred at the edges.

Roasting brings out the natural sweetness and reduces acidity.

4. Bring the soup to a gentle simmer over medium-low heat.

5. Simmer for 5–10 minutes to deepen flavor.

6. Stir in cream or coconut milk if using.

Your Roasted Tomato and Red Pepper Soup is ready when:

• Texture is smooth and velvety.

Turn off heat and let the soup rest for 5 minutes.

Before serving:

• Taste and adjust salt.

• Add a small squeeze of lemon if needed.
