Save The first time I made roasted red pepper soup was after a trip to a local farmers market where the peppers were so vibrant they practically glowed. I'd bought way too many, and as they sat on my kitchen counter, their sweet scent reminded me of summers in Spain. Something about their glossy skins and the way they charred under heat sparked a memory of street vendors roasting peppers over open flames. I decided then that these beauties deserved more than just being sliced into a salad.
Last autumn, I brought a thermos of this soup to my friend's pottery studio where we were taking a weekend workshop. The rich color matched perfectly with the red clay we were using, and during our lunch break, everyone wanted to know what was in my cup. By the end of the day, I'd promised the recipe to six people, each one commenting on how the harissa gave it such an unexpected warmth without overwhelming the sweet peppers.

Ingredients
- Red bell peppers: Look for peppers with tight, glossy skin and substantial weight for their size, which indicates freshness and juiciness that transforms into incredible sweetness when roasted.
- Harissa paste: This North African chili paste adds a complex heat that regular hot sauce simply cannot match, and I keep mine in the freezer portioned in ice cube trays for recipes just like this.
- Smoked paprika: After running out of regular paprika once, I substituted the smoked variety and never looked back, as it adds a depth that makes people swear you spent hours developing the flavor.
- Day-old bread: Slightly stale bread actually makes better croutons because it absorbs less oil and crisps more evenly than fresh bread, something my grandmother insisted upon with surprising firmness.

Instructions
- Char those peppers:
- Crank your oven to 425°F and arrange those halved peppers skin-side up like they're sunbathing. You want the skins to blacken and blister, which releases their natural sweetness and creates that distinct roasted flavor.
- Make crouton magic:
- Toss your bread cubes with olive oil and seasonings until every piece looks evenly coated. Spread them out so they're not touching each other, giving them space to get uniformly golden and crunchy.
- Build the flavor base:
- Sauté the onion, garlic, and carrot until they soften and become fragrant, creating the aromatic foundation. When you add the spices, you'll notice the kitchen fills with an intoxicating smell that will make anyone nearby suddenly interested in what you're cooking.
- Blend to perfection:
- Use your immersion blender with confidence, moving it up and down to catch every bit. The transformation from chunky mixture to silky soup happens quickly, and you'll know it's ready when the color deepens to a vibrant orange-red.
- Finish with finesse:
- Stirring in the cream creates beautiful swirls before it fully incorporates, adding a richness that rounds out the flavor. Taste at this point and be fearless about adjusting the seasoning, as soup often needs more salt than you might initially think.

I served this soup at a dinner party where one guest was particularly skeptical of vegetarian dishes. As he cautiously took his first spoonful, his eyebrows raised, and he asked for the recipe before he'd even finished the bowl. Later he confessed it had changed his mind about meatless meals having enough flavor to stand on their own. That night, this simple soup bridged a culinary divide I never expected it could.
Make It Ahead
This soup actually improves with time, developing deeper flavors after a day in the refrigerator. I often make a double batch on Sunday afternoons while listening to podcasts, storing half in the freezer in individual portions for those inevitable busy weeknights. The gentle ping of the microwave reheating a serving has become a comforting sound on rainy evenings when I'm too tired to cook but still want something nourishing.
Perfect Pairings
Finding the right accompaniment to this soup was a delightful journey of trial and error that involved many leisurely weekend lunches. A crusty sourdough bread makes an excellent vehicle for mopping up the last bits of soup, but for a complete meal, I discovered that a simple arugula salad with lemon vinaigrette and shaved parmesan provides the perfect peppery contrast to the sweet, smoky flavors of the soup. The brightness cuts through the richness and cleanses the palate between spoonfuls.
Troubleshooting Tips
After making this soup dozens of times, I've encountered almost every possible challenge and found simple solutions for each one. If your soup seems too thick, vegetable broth works better than water for thinning it out while maintaining flavor, and if it's too thin, a few minutes of additional simmering usually does the trick rather than adding a thickener. Sometimes the peppers themselves can vary in sweetness depending on the season, so taste as you go and adjust accordingly.
- If your soup has separated after refrigeration, gently reheat it over low heat while whisking continuously.
- Store leftover croutons in an airtight container with a slice of bread to absorb moisture and keep them crispy for up to three days.
- For a dinner party shortcut, make the soup base a day ahead and add the cream just before serving for the freshest flavor.

Recipe Questions & Answers
- → Can I use jarred roasted peppers instead of fresh?
Yes, jarred roasted red peppers work well as a time-saving alternative. Use approximately two 12-ounce jars, drained well. The flavor will be slightly less smoky but still delicious. Skip the roasting step and proceed directly with sautéing the aromatics.
- → How spicy is this soup with harissa?
The harissa provides a gentle, warming heat rather than overwhelming spice. One tablespoon yields a mild to medium level that most palates enjoy. Adjust to your preference by starting with half the amount and adding more gradually.
- → Can I freeze this soup?
Absolutely. This soup freezes beautifully for up to 3 months. Cool completely before transferring to airtight containers. Thaw overnight in the refrigerator and reheat gently on the stovetop. Add fresh croutons when serving for the best texture.
- → What can I serve alongside this soup?
A simple green salad with lemon vinaigrette balances the richness beautifully. Grilled cheese sandwiches, crusty baguette slices, or focaccia also make excellent accompaniments. For a lighter meal, serve with fresh vegetable crudités and hummus.
- → How do I make the croutons gluten-free?
Simply substitute gluten-free bread cubes for regular bread. Look for a sturdy gluten-free loaf that holds its texture well when baked. The seasoning and baking time remain exactly the same, yielding perfectly crispy gluten-free croutons.
