Roasted Red Pepper Soup

Featured in: Weeknight Dinners

This vibrant soup combines the natural sweetness of fire-roasted red peppers with rich caramelized garlic, creating a luxurious base that's perfectly balanced with North African spices. The harissa adds just enough warmth to elevate the flavors without overwhelming the palate. After roasting the vegetables until tender and slightly charred, everything simmers together with aromatic vegetables before being blended into an incredibly smooth, restaurant-quality finish.

What makes this version particularly special is the depth achieved through proper roasting techniques—the peppers develop those coveted smoky notes while the garlic becomes sweet and mellow. A hint of smoked paprika and ground cumin reinforces the Mediterranean profile, making each bowl deeply satisfying yet surprisingly light. The result is a velvety, colorful soup that feels elegant enough for dinner guests but simple enough for a quick weekday lunch.

Instructions

Step 1: Roast the Vegetables
Preheat your oven to 425°F (220°C). Place the red peppers and unpeeled garlic cloves on a baking sheet. Drizzle with 1 tablespoon olive oil and roast for 25–30 minutes, turning once, until the peppers are charred and soft and the garlic is caramelized.
Step 2: Prepare the Peppers
Transfer roasted peppers to a bowl and cover with a plate or plastic wrap. Let steam for 10 minutes, then peel and deseed the peppers. Squeeze the roasted garlic from its skins.
Step 3: Sauté Aromatics
In a large pot, heat the remaining 1 tablespoon olive oil over medium heat. Add the chopped onion, carrot, and celery. Cook for 5–7 minutes, stirring, until softened.
Step 4: Combine Flavors
Add roasted peppers, roasted garlic, smoked paprika, cumin, and harissa paste. Stir well and cook for 1 minute until fragrant.
Step 5: Simmer
Pour in the vegetable broth. Bring to a boil, then reduce heat and simmer for 10 minutes.
Step 6: Blend and Season
Use an immersion blender (or transfer soup in batches to a blender) to puree until silky smooth. Season with salt and pepper to taste.
Step 7: Garnish and Serve
Serve hot, garnished with crème fraîche or yogurt and fresh herbs. Add crusty bread on the side if desired.

Zusatztipps für die Zubereitung

To ensure a perfectly smooth soup, make sure to remove as many charred skin fragments from the peppers as possible after steaming. If using a countertop blender instead of an immersion blender, remember to blend in small batches and leave the lid slightly ajar to allow steam to escape.

Varianten und Anpassungen

For an extra layer of smokiness, use fire-roasted peppers or add a pinch of chili flakes. This soup can easily be made vegan by omitting the crème fraîche or yogurt garnish, or by substituting it with a plant-based alternative like coconut cream or cashew cream.

Recipe Questions & Answers

Can I use jarred roasted peppers instead of fresh?

Yes, jarred roasted red peppers work well in a pinch. Look for ones packed in water rather than oil for better control over the final flavor. You'll need about 2-3 jars to equal 4 fresh peppers. Skip the roasting step and proceed with sautéing the vegetables.

How can I make this soup vegan?

Simply omit the crème fraîche or yogurt garnish, or substitute with your favorite plant-based alternative like coconut yogurt, cashew cream, or almond-based sour cream. The soup itself is completely vegan as written.

What's the best way to adjust the spice level?

Start with 1 teaspoon of harissa and taste before adding more. For a milder version, reduce to ½ teaspoon or omit entirely. If you prefer more heat, gradually increase to 2 teaspoons. The smoked paprika adds flavor without significant spice.

Can I freeze this soup?

Absolutely. Let the soup cool completely before transferring to airtight containers or freezer bags. It will keep well for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stove, adding a splash of broth if needed to adjust consistency.

What can I serve alongside this soup?

Crusty bread is perfect for dipping, but grilled cheese sandwiches, garlic bread, or a simple green salad with vinaigrette also complement the flavors beautifully. For a more substantial meal, pair with a quinoa salad or roasted vegetables.

Why do I need to cover the roasted peppers?

Covering the hot peppers creates steam that helps loosen the skins, making them much easier to remove. This technique also ensures the peppers continue cooking slightly, becoming even more tender and flavorful before blending.
