Ingredients
Servings
6
- 3 pounds ripe Roma tomatoes, halved
- 1 large yellow onion, chopped
- 4 cloves garlic, peeled
- 3 tablespoons olive oil
- 1 teaspoon sea salt
- ½ teaspoon freshly ground black pepper
- 1 teaspoon dried oregano
- 1 teaspoon smoked paprika
- 2 cups gluten-free vegetable broth
- ½ cup fresh basil leaves, loosely packed
- 1 cup raw cashews, soaked in hot water for at least 2 hours or overnight
- ¾ cup water (for cashew cream)
- 1 tablespoon lemon juice
- fresh basil leaves and a drizzle of extra cashew cream
Instructions
-
Preheat your oven to 400°F (200°C).
-
Arrange the halved Roma tomatoes, chopped onion, and garlic cloves on a large baking sheet.
-
Drizzle with olive oil and season evenly with sea salt, black pepper, dried oregano, and smoked paprika; toss gently to coat.
-
Roast vegetables for 30 minutes, turning once halfway through, until tomatoes are softened and slightly caramelized.
-
Meanwhile, drain and rinse soaked cashews. Blend cashews with ¾ cup water and lemon juice in a high-speed blender until silky smooth; chill the cashew cream.
-
Transfer the roasted tomatoes, onion, and garlic to a large stockpot.
-
Add the gluten-free vegetable broth and fresh basil leaves.
-
Use an immersion blender to puree the soup until creamy and smooth, or blend in batches in a standard blender and return to the pot.
-
Warm the soup over medium heat for 5 minutes, adjusting salt and pepper to taste.
-
Serve hot, garnished with a swirl of chilled cashew cream and additional fresh basil leaves if desired.
-
Store leftovers airtight in the refrigerator for up to 4 days or freeze portions for up to 3 months.

Texture Expectations
This gluten-free Roasted Tomato and Basil Soup with Cashew Cream delivers a luxuriously smooth and creamy texture without the need for gluten-containing thickeners. Roasting the tomatoes and aromatics deepens flavors while softening them, yielding a velvety base when blended.
The soaked cashews create a rich, silky mouthfeel that rivals traditional dairy cream soups yet keeps the recipe vegan, dairy-free, and gluten-free. This creamy cashew topping balances the tomatoes’ natural acidity for a harmonious finish.
Compared to gluten soups thickened with flour or roux, gluten-free soups like this often feel lighter but remain satisfyingly creamy thanks to pureed vegetables and nuts. To increase thickness, reduce broth volume slightly or add additional soaked cashews during blending.
Texture varies slightly by blending method: immersion blenders produce a pleasantly rustic texture with subtle chunkiness, while high-speed blenders yield an ultra-smooth, velvety consistency.
Similar texture considerations apply in gluten-free baking and other Freeflourish recipes, where crumb tenderness and moisture may differ due to alternative ingredients like nuts and fibers. These unique qualities enrich gluten-free cooking’s diverse appeal.
Dining With Non Gf Family Note
Sharing gluten-free meals with family members who consume gluten can be seamless and enjoyable with mindful practices. To avoid cross-contamination and keep all diners satisfied, consider these helpful guidelines:

- Thorough Surface Cleaning: Clean countertops and tools diligently, especially after preparing gluten-containing foods.
- Separate Storage: Keep gluten-free flours and ingredients in clearly labeled, sealed containers away from gluten-containing products.
- Cooking Order: Prepare gluten-free dishes before gluten-containing meals when possible to minimize contamination risk.
- Educate Household Members: Raise awareness about gluten cross-contact routes to promote safe cooking cooperation.
- Clear Labeling: Serve gluten-free dishes with dedicated utensils and mark foods clearly during shared meals.
- Inclusive Recipes: Choose Freeflourish recipes categorized as Family-Friendly, Quick & Easy, and Holiday & Seasonal featuring tags like glutenfree and kidfriendly, so everyone can enjoy safe, delicious meals together.
