This roasted red pepper soup is as quick and easy to make as it is healthy. It’s packed with peppers, tomatoes, and quinoa, and only takes about an hour start to finish.
It’s not exactly a secret that I’m a big fan of soups. Whether it’s cold outside, or I’ve just had a long, exhausting day, there’s nothing quite as comforting as a steaming bowl of hearty soup. This roasted red pepper soup is one of my favorites, because it checks all the boxes that I look for in a soup. It’s comforting, rich, filling, healthy, and super easy to make. Plus, it's vegan and gluten-free!
Soup is often served as a side, but this roasted red pepper soup is a meal all by itself. The secret? It has quinoa in it! Adding a superfood like quinoa to a soup full of veggies like peppers and tomatoes makes for an incredibly healthy and well-rounded meal. Add in the fact that it only takes about an hour to make this soup, and it’s not hard to see why this is one of my favorite recipes.
What You’ll Need
Here’s everything you need to make this comforting red pepper and tomato soup. Scroll to the recipe card at the bottom of the article to see the exact quantities for each ingredient.
- Red peppers – You’ll want to deseed the peppers.
- Tomato sauce
- White onion – You can also use yellow or red onions, but a white onion is preferable.
- Olive oil
- Pepper – Be sure to use freshly-ground black pepper.
- Dried thyme
- Dried oregano
- Red pepper flakes

- Cooked quinoa
- Hot sauce – This is an optional ingredient.
How to Make Roasted Red Pepper Soup
Here’s how to make this vegan red pepper and quinoa soup.
- Prep the peppers. Put the red peppers on a baking sheet, skin-side up. Press them down to flatten them, and turn on your broiler.
- Roast the peppers. Put the peppers in the oven under the broiler, and roast them until the skins are blackened. This should take 10-15 minutes.
- Peel the peppers. Remove the peppers from the oven, and place them in a heat-proof resealable bag. Let them sit for 15 minutes, then remove them from the bag and peel off the skin. Slice the peppers and set them aside.
- Heat the aromatics. Heat the oil in a pot over medium-high heat. Add the onions and garlic to the pot, and sauté until the onions are translucent.
- Add the rest of the ingredients. Add the tomatoes, tomato sauce, red peppers, vegetable broth, cooked quinoa, herbs, and spices to the pot.
- Cook. Bring the soup to a boil, then lower the heat to a simmer. Put a lid on the pot, and cook for 20-25 minutes.
- Blend. Use an immersion blender to blend the soup into a smooth consistency. If you don’t have an immersion blender, transfer the soup to a standing blender, and blend.
- Serve. If you’re using hot sauce, stir it into the smooth soup, then serve while hot.
Tips for Success
Here are a few tricks and tips for making this hearty and comforting soup.
- Use homemade broth. One way to elevate any soup is to use a homemade broth. The flavor you get from homemade stock is so much better than anything you’ll buy in the store. This recipe is great with any kind of vegetable broth, but it reaches a new level with homemade broth. I like to use my Instant Pot mushroom vegan bone broth.
- Add extra cooking time. One of my favorite things about this recipe is how quick and easy it is to make. But if you have extra time, almost any soup can benefit from simmering a little bit longer. The longer you cook this soup, the more intense the flavors will become. If you have the time, cook it for an hour or two. However, keep an eye on the consistency, as you may need to add a little more veggie broth if you cook it longer.
- Salt at the end. When adding the ingredients to the soup, go light on the salt. Then, before serving, taste the soup and add salt as needed. Different veggie broths and hot sauces have different sodium levels, and the amount of time that you cook the soup will impact how salty it is. Wait until the very end to add the rest of the salt, to make sure that you don’t over-salt the soup.

This soup looks amazing and I am with you, I can’t get enough soup once fall hits. I have been dreaming of lots of different soup concoctions already. Off to check out that recipe now.
Soup is the best! Can’t wait to start making chilis and stews. Still a bit too warm – this was my bridge between summer and fall 🙂
I made a roasted red pepper humus last month and am now wondering if I should try quinoa instead of chick peas……
Im making soup today too!
Great idea!! I’ve heard of making quinoa hummus but never tried it. You’ll have to tell me if it works out 🙂
I LOVE roasted red pepper soup, but I’ve never tried it with quinoa– just checked out the post on easy eats and it looks so good! I love a new way to try something I’ve done before 🙂
I absolutely love soup myself. They’re easy, they’re filling, they’re comforting and they can be really beautiful. Like yours! It’s so vibrant and I like that you used quinoa as it adds a little nutritional backbone 😉
Thank you Jessica! This soup is really tasty and perfect for the fall. Soups are just the best…
I don’t like tomato soup, or red pepper at ALL, but had both in the house and made this. It was SO good, I’m going to make it again today. I’m blown away. Thanks 🙂
Yay! That just made my day 🙂 So happy you enjoyed it!!
I can’t see the recipe for this soup anywhere! please help I’d love to try it.

Would love to know if you try it!

I found this recipe on pinterest and made it today. It was pretty easy and is spicy and delicious! I didn’t even add the milk and I’m not going to because I like it just the way it is. My soup turned out much lighter than your dark-red soup picture but it’s still fantastic! Thanks!
So happy it worked out for you Marianne 🙂 I also love the spice factor! I was just thinking about this soup yesterday. I think I need to make it again!
Is it possible to get this recipe? I bought all the ingredients for it and the link for the recipe is no longer available. 🙁
Made this and it was absolutely delicious! I highly recommend it! I halved the recipe, and only had half a red pepper and half a yellow pepper from a previous night, so I used those. It still came out nice, red, and tasty.
So glad you enjoyed it! Thanks for sharing 🙂
Oh! This soup looks and sounds perfect!
love tomato soup, and love quinoa but never have I had this combo. I am excited to give this a try this weekend
Can’t wait to hear how it turns out for you!! xx
Whoa! I think it’s super cool that you blend in the quinoa to the soup. I am going to have to give this method a try…
Really tasty soup, made it last night. I didn’t roast the peppers exactly as per intrusions and omitted the quinoa, but it was so tasty!! Thank you!
I’m so glad you enjoyed it!! xox
Made this soup tonight and it was super delicious!! I served it with a little sour cream and some Parmesan cheese..
Yum!! I’m so happy you enjoyed it 🙂 xox
Made this soup – absolutely delicious!
YES! So happy to hear that, Alyssa 🙂
Excited to try this recipe! I’m curious if there’s any reason not to increase the liquid and cook the quinoa in the step 3 rather than using already cooked quinoa? I’m also thinking of using canned tomatoes, do you know about how much canned I would use for your 2 tomato equivalent? Trying to save myself any extra steps I can! Thanks for this recipe!
Yeah you can absolutely do that! I had leftover quinoa which is why I added it in. And I’d say 1 15 oz can should work 🙂
I finally made this soup. Delicious. However…Instead of fresh tomatoes, I used a can of fire roasted diced tomatoes. I hadn’t noticed that the can also contained medium green chilies until it was too late. So I drained and rinsed the diced tomatoes and opted not to add any red pepper flakes as I am not a fan of hot and spicy. The soup has a little kick from the chilies so I added fresh lime juice. Will definitely make again but without the added chilies. ????
So who makes a soup from scratch in the beginning of summer? I did!!! This soup is sooo good. I didn’t blend it completely because I like a little chunk in my soup but it was good. I’m not a pepper (spice person) so I would probably back off the red pepper a bit. Thanks for the recipe. I am looking for to adding this to my winter meals.
Yay!!! I’m so so happy you enjoyed it! Yay for soup season all year long 🙂 xx
Hi this soup looks great. Wondering if anyone has had good results freezing it? Would be nice to have a good supply on hand.
I have and it works great!
Love your new web design, all of your videos and recipes but sweetie, please don’t tell people to put hot food in a plastic bag as you did with the red peppers. I accomplish the same thing by using a glass bowl and a tea towel. No nano-micro-plastics in my food.
Just made this soup and it has turned out delicious. I had to make a few adjustments- I used one red and one green pepper, I used dried quinoa instead of cooked and I also threw in lots of cherry tomatoes as had these left over in fridge and they were starting to soften. I didn’t have tinned tomoato sauce so used a tin of chopped tomatoes instead. The soup turned out perfec and can’t wait to make again! Oh one last thing I didn’t peel the peppers….
Sounds incredible! Love the addition of green better 🙂 Thank you so much for sharing!
Lovely little soup. Very easy. I didn’t have a tomato so I subbed a can of no salt added, fire roasted tomatoes. Perfection!!
So glad you enjoyed it!
This is my new fav soup!! It is just lovely! I did not have a fresh tomato, so used a can of no salt added fire roasted tomatoes.
Topped my soup with vegan feta and my oh my!
Thank you for sharing this creation!
So happy to hear that!! That topping sounds INCREDIBLE!
