What is Roasted Red Pepper Soup?

Roasted red pepper soup is a creamy, savory soup made with roasted red bell peppers blended with aromatics and broth. Roasting the peppers first gives the soup its signature smoky-sweet flavor and vibrant red color.

Why You’ll Love This Recipe

  • This smoky, creamy roasted red pepper soup is ready in under 30 minutes, made with just a handful of pantry staples, and all comes together in one blender + one pot.
  • The star ingredient—red bell peppers—is loaded with vitamin C, vitamin A, and powerful antioxidants that help support your immune system and reduce inflammation. Roasting them brings out their natural sweetness and makes this soup taste like you worked way harder than you actually did.
  • Unlike most creamy soups that rely on dairy or canned shortcuts, this one is 100% plant-based and gets its richness from roasted sweet potatoes and garlic cloves roasted in their skins (hello, flavor bomb!). We also kick it up a notch with smoked paprika and a hit of lemon juice to balance the sweetness and add depth.
  • All you need is a high-speed blender (like a Vitamix blender) or immersion blender, a stove top and a soup pot—that’s it. It reheats beautifully, making it ideal for meal prep. Store it in stackable glass 2-cup containers, freeze in Souper Cubes Freezer System or easy grab-and-heat lunches later in the week. Pair it with a crusty slice of sourdough or a hearty salad recipe and you’re good to go.

How to Make Roasted Red Pepper Soup

To make this roasted red pepper soup, you’ll need to roast your red peppers first. This is how you get a total flavor upgrade thats smoky and satisfying. Here’s four different ways you can do this, depending on the time of year and equipment you have.

Oven Roasted Red Peppers

  • This is the method I use in this recipe. Slice peppers in half, remove seeds, and place cut-side down on a parchment-lined baking sheet. Roast at 425°F for 20–25 minutes, until skins are blistered and slightly charred.

Barbecued Red Peppers

  • Place whole red peppers directly on a hot grill. Turn every few minutes until the skin is blackened and blistered all over (about 10–15 minutes).

Toasted Red Peppers

  • Halve and deseed peppers, then place them skin-side up on a foil-lined tray. Roast at the toaster’s highest temperature setting for about 20 minutes, or until the skin is dark and blistered.

Stove Top Red Peppers

  • Using a gas burner, place the whole pepper directly over the flame. Use tongs to rotate every few minutes until completely charred (takes about 10 minutes).

Once you’ve decided your method for roasting the red bell peppers, you’ll want to roast sweet potatoes, red bell peppers, onion, and garlic at 425°F until soft and caramelized. Blend with vegetable broth until smooth, then simmer with smoked paprika and lemon juice. Adjust seasoning to taste, then serve warm with cashew cream, green onions, and a sprinkle of smoked paprika on top.

Storing and Reheating Tip

Let the roasted red pepper soup cool completely before transferring it to an airtight container. It will keep in the fridge for up to 5 days. Making a bigger batch? It freezes beautifully for up to 3 months—just remember to leave a little room at the top of the container for expansion. Reheat gently on the stove over medium-low heat, stirring occasionally, or microwave individual portions, stirring halfway through. If it thickens, add a splash of broth or water to bring back that silky texture, and the same trick works for the rest of my plant-based soups.

Common Questions

How to make the best roasted red pepper soup?

Start by roasting fresh red bell peppers along with sweet potatoes, onion, and garlic until tender and slightly charred. Then blend the roasted veggies with vegetable stock until smooth. Simmer with smoked paprika, lemon juice, and your choice of seasonings to develop rich, layered flavors. Finish with a creamy topping like cashew sour cream for extra indulgence.

Do you need to peel roasted red peppers for soup?

Peeling roasted red peppers is optional. The skin can add fiber (which I love and choose to keep the skin on), which can add a slight texture and smoky bitterness. If you prefer a silky smooth soup, removing the skins after roasting helps create a creamier texture. Simply roast until charred, then place the peppers in a covered bowl or plastic bag to steam, this loosens the skin for easy peeling.

What spices are good in roasted red pepper soup?

Smoked paprika is a must for that deep, smoky flavor. You can also add cumin for warmth, cayenne pepper or chili flakes for a bit of heat, and a pinch of black pepper for a subtle bite. Fresh herbs like thyme or oregano work well too, enhancing the overall aroma and complexity.

Are roasted red peppers healthy?

Absolutely! Roasted red peppers are packed with vitamin C, antioxidants, and fiber. They support immune health, reduce inflammation, and provide essential nutrients like vitamin A and potassium. Roasting enhances their natural sweetness without adding calories or fat, making them a nutritious addition to any meal.

    I used jarred roasted red peppers and rinsed them well, still loved how it came out, altho I have roasted veggies for soups before, and I will be glad to roast the peppers the next time I do this soup, as we loved it! Garnished with a little sriracha sauce which gave it a bite!

  2. 4 stars
    I used fire roasted tomatoes and I loved the flavor. I did not use the cashew cream but will next time as I can see how that will completely add to the overall finish. I will keep this one for sure!

    1. Fire roasted tomatoes are having a whole moment in our 10 Day Soup Challenge for sure. Great swap in! Can’t wait to hear what you think of the cashew cream next time.

  3. 5 stars
    Love this soup. Great flavor with a little spice. Will add more red pepper next time. Made it per the directions and will do so again many more times.

    1. So glad it’s part of the regular rotation now, Neil! 🙂
