Ingredients
This soup relies on a handful of high‑impact ingredients that each play a distinct role. The roasted red peppers provide a sweet, smoky backbone, while the cashews lend a natural creaminess without dairy. Aromatics such as onion and garlic build savory depth, and a splash of sherry vinegar brightens the finished bowl. Fresh herbs and a drizzle of good olive oil add the final polish.
Main Ingredients
- 4 large red bell peppers
- 1 cup raw cashews (soaked 4 hrs)
- 1 medium yellow onion, diced
- 2 cloves garlic, minced
Liquid & Flavor Base
- 4 cups vegetable broth (low‑sodium)
- 2 tbsp extra‑virgin olive oil
- 1 tbsp sherry vinegar
Seasonings & Garnish
- ½ tsp smoked paprika
- Salt and freshly ground black pepper, to taste
- ¼ cup fresh basil leaves, torn
- Optional: ¼ cup plain Greek yogurt for swirl
The roasted peppers give the soup its signature ruby hue and sweet‑smoky backbone. Soaked cashews provide a velvety texture without the need for heavy cream, keeping the dish light yet indulgent. Aromatics and smoked paprika deepen the savory profile, while sherry vinegar adds a bright acidity that balances the natural sweetness. Finishing with fresh basil and a drizzle of olive oil lifts the flavors, creating a harmonious bowl that feels both rustic and refined.
Step-by-Step Instructions
Roasting the Peppers
Preheat your oven to 475°F (245°C) and line a baking sheet with foil. Slice the red bell peppers in half, remove seeds, and place them skin‑side up. Drizzle with 1 tbsp olive oil and sprinkle a pinch of salt. Roast for 20‑25 minutes, turning once, until the skins blister and blacken. The charred skins impart a deep smoky flavor essential to the soup’s character.
Preparing the Soup Base
While the peppers roast, heat the remaining 1 tbsp olive oil in a large pot over medium heat. Add the diced onion and sauté for 5‑6 minutes, or until translucent and lightly caramelized. Stir in the minced garlic and smoked paprika, cooking for another 30 seconds—this releases the spice’s aroma without burning it.
- Peel the Peppers. Transfer the hot roasted peppers to a bowl, cover with plastic wrap, and let steam for 5 minutes. The steam loosens the skins, making it easy to peel them off. Removing the skins prevents bitterness and ensures a smooth texture.
- Blend the Soup. In a high‑speed blender, combine the peeled peppers, soaked cashews, sautéed onion‑garlic mixture, vegetable broth, and sherry vinegar. Blend on high until the mixture is completely smooth, about 1‑2 minutes. The cashews melt into a creamy base, eliminating the need for flour or cream.
- Simmer Gently. Pour the blended soup back into the pot and bring to a gentle simmer over low heat. Cook for 10‑12 minutes, stirring occasionally, until the flavors meld and the soup thickens slightly. Taste and adjust seasoning with salt and pepper.
- Finish with Fresh Herbs. Remove the pot from heat and stir in torn basil leaves. The fresh herb adds a bright, aromatic finish that balances the smoky depth.
- Plate and Garnish. Ladle the hot soup into bowls, drizzle each serving with a thin stream of olive oil, and optionally swirl a spoonful of Greek yogurt for added tang. Sprinkle a few extra basil leaves on top for color.
Tips & Tricks
Perfecting the Recipe
Soak Cashews Properly: Soak raw cashews for at least 4 hours or overnight. This softens them, ensuring a completely smooth blend without grainy texture.
Peel Peppers While Hot: Allow peppers to steam under a bowl for 5 minutes; the skins slip off easily, saving time and preserving flavor.
Flavor Enhancements
Add a pinch of cayenne for gentle heat, or stir in a teaspoon of smoked sea salt for extra depth. A splash of heavy cream or coconut milk at the end creates an even richer mouthfeel if you don’t mind dairy.
Common Mistakes to Avoid
Skipping the peeling step leaves bitter skin fragments in the soup. Also, avoid boiling the soup vigorously; a gentle simmer preserves the creamy texture and prevents the cashew base from separating.
Pro Tips
Use a Hand‑Held Immersion Blender: If you prefer fewer dishes, blend the soup directly in the pot for a seamless, ultra‑smooth finish.
Season in Layers: Add a pinch of salt after roasting, again after sautéing, and a final adjustment before serving. Layered seasoning builds depth without over‑salting.
Reserve a Spoonful of Soup for Swirls: Before garnishing, set aside a small amount to swirl in yogurt or crème fraîche for a striking visual contrast.
Serve Immediately: The soup tastes best hot; if reheated, add a splash of broth to revive its silky texture.
Variations
Ingredient Swaps
Replace red bell peppers with charred fire‑roasted tomatoes for a tangier profile, or swap cashews for soaked almonds for a slightly nuttier flavor. For a smoky twist, add a teaspoon of chipotle in adobo instead of smoked paprika.
Dietary Adjustments
The recipe is naturally gluten‑free. For a vegan version, omit the Greek yogurt garnish and use plant‑based broth. To keep it keto, reduce the broth volume slightly and add a splash of heavy cream or coconut cream for richness.
Serving Suggestions
Pair the soup with a warm slice of sourdough or a crisp focaccia. A side of quinoa salad with lemon vinaigrette adds protein and texture. For a festive touch, serve in hollowed‑out roasted peppers as edible bowls.
Storage Info
Leftover Storage
Cool the soup to room temperature, then transfer it to airtight containers. Refrigerate for up to 4 days. For longer keeping, freeze in portion‑sized containers for up to 3 months; place a layer of plastic wrap directly on the surface before sealing to prevent freezer burn.
Reheating Instructions
Reheat gently on the stovetop over low heat, stirring occasionally, and add a splash of broth or water if the soup thickens too much. In the oven, cover the bowl with foil and warm at 350°F for 15 minutes. Avoid boiling, which can cause the cashew base to separate.
