Roasted Carrot and Red Pepper Peanut Soup

Around this time every year I get the urge to turn on my oven, let the kitchen get nice and toasty, and roast up some vegetables.

Then I got the urge to blend them up into soup.

Courtesy of urban living, we don’t have a grill and there are times I really miss the bite and sharpness that grilled food possesses. I tried to duplicate the smoky quality of grilled vegetables by roasting carrots and red peppers in the oven until they were very well done and my strategy paid off.

The resulting soup was rich, smoky, and had some of the charcoal-infused flavor I wanted without tasting like I just ate a lump of coal.


I began by roasting one pound of carrots. I used to think one pound sounded like a lot but it’s really just about 10 average-sized carrots and one pound fits on one baking tray. By the time they’re peeled, trimmed, and diced into one-and-a-half-inch chunks, and because they shrivel dramatically while baking, one pound turns out to be less than you think.

Before their journey into the hot oven, I drizzled them with a touch of olive oil, and generously sprinkled with Kosher salt and black pepper. Allowing the carrots to caramelize very well, and roasting them just to the edge of what some would call burnt, is actually desirable for soup-making because it provides the finished soup with body and depth of flavor. If vegetables are only lightly roasted, the flavor gets lost and at that point, you may as well just steam them in the microwave because it’s a lot quicker.

While the carrots roasted on one tray, I roasted a ginormous red pepper on another. I found the super-sized specimen at Trader Joe’s, but if your pepper options are smaller, I’d roast two. When roasting peppers, be mindful that they shrivel very dramatically due to their high water content.

Do not make the mistake of trimming the pepper too small or you’ll end up with blackened bits of charcoal and burnt red skin laying on the baking sheet and wonder where the pepper you put into the oven went. For the average-sized pepper, slice it into no more than four to six pieces. Mine was huge and seven slices took up a whole baking tray before roasting but emerged from the oven taking up less than half the surface area of the tray.

I didn’t flip the vegetables midway through roasting for a variety of reasons. First, I claim laziness. I really didn’t want to painstakingly flip over 67 little carrot pieces with a tongs. Secondly, I wanted one side of them to get pretty blackened for the flavor aspect. And lastly, I got distracted while they were roasting and realized after the halfway point had passed that I’d just continue folding my laundry rather than flipping carrots and peppers.

After the vegetables emerge from the oven, put them into a Vita-Mix, blender, or food processor, along with one can of coconut milk, and about one-half cup of peanuts or about one-quarter cup peanut butter and blend. The soup would have been fine coarsely pureed and with some texture to it, by just pulsing it in a food processor or lightly going after it with an immersion blender, but because I put it into the Vita-Mix, sooner rather than later I had an incredibly smooth puree.

The flavor of this soup is just so layered and chock full of dimension. First, the caramelized carrots add a touch of sweetness while the peppers add a little heat and smokiness.

The coconut milk adds a creaminess, and in conjunction with the residual olive oil that engulfs the roasted vegetables, you’re left with a soup with some meat on it’s vegan bones. However, for those who aren’t huge fans of coconut-flavored food, not to worry because that flavor of all is the least distinct.

However, the peanuts or peanut butter flavor is quite distinct and once added, the pop of nuttiness cannot be un-done. I love peanut butter, but you may wish to add it or the peanuts slowly just to make sure you like that flavor note; or try almond butter or sunflower seed butter. I love the creaminess and richness from peanut butter and it was welcomed with open arms. And open mouths.

I didn’t season the soup with additional salt, pepper, or spices, other than the sprinkle that was added to the vegetables before roasting. However, seasoning with anything from cayenne pepper to cinnamon to nutmeg to garlic to curry is possible. The options are vast and the seasonings can easily be customized to taste.

While blending, I added a tablespoon of agave and its clean sweetness counter-balanced the smokiness and earthiness from the roasted vegetables. Depending on how well-done your vegetables are, this may or may not be needed. A dash of maple syrup would also be lovely.

Garnished with vegan sour cream, peanuts, and carrots, this soup was hearty without being stuffing in that lobster bisque or potato chowder kind of way. The beauty of vegan, gluten-free, soy-free, and almost salt-free food is that I feel satisfied, not stuffed, after eating and I’m also not guzzling water for five days to counteract the sodium onslaught that I find is the case with most commercially-prepared soup.

The batch makes about 24 ounces, or about six generous bowls and so there are leftovers to a point, without making a ridiculous amount so not to worry that you’ll be eating the same thing for days and days. Then again, soup freezes very well, too.

This hit the spot so well though that I wouldn’t have minded more leftovers.

Roasted Carrot and Red Pepper Peanut Soup (vegan, gluten-free, soy-free)
Prep time
Cook time
Total time
Serves: Makes about 4 cups of very thick soup, which can be thinned to increase the yield
  • 1 pound carrots, peeled and chopped into about 1½-inch chunks
  • 1 very large or 2 medium red bell peppers, deseeded and sliced into 4 to 6 large wedges
  • 2 tablespoons olive oil
  • 1 teaspoon Kosher salt, or to taste
  • ½ teaspoon black pepper, or to taste
  • one 14-ounce can coconut milk (I used Trader Joe’s Light Coconut Milk)
  • ½ cup peanuts (unsalted, salted, plain, honey roasted or your favorite type) or ¼ cup creamy peanut butter
  • 1 to 2 tablespoons agave, maple syrup, or honey, optional and to taste
  • optional seasonings - any used are to taste - red pepper flakes, cayenne pepper, chili powder, cinnamon, ground ginger, ground nutmeg, garlic powder, onion powder, curry powder, paprika, smoked paprika
  • optional additional vegetables to roast with the carrots and peppers- garlic, onions, sweet potatoes, potatoes, squash, pumpkin, zucchini, beets, turnips, parsnips
  1. Preheat oven to 400F. Prepare two baking sheets by lining them with Silpats, parchment paper, aluminum foil, or spaying sheets with cooking spray; set aside. Peel and chop the carrots into about 1½-inch chunks, keeping them approximately the same size so they cook evenly; place carrots on one baking sheet. Quarter the pepper, or slice it into 5 or 6 large wedges, noting that the pepper must be sliced and kept much larger than the carrots because it will shrink in size by nearly half when roasted and if sliced too small to begin with, it will simply char. Place pepper slices on the other baking sheet. Evenly drizzle olive oil over top of vegetables and sprinkle them with salt and pepper. Roast for about 40 minutes (I roasted for 45 minutes because I got distracted; 40 minutes would have been better), or until carrots are fork tender and have browned and caramelized; peppers will be soft, limp, and blackened around the edges. I did not bother flipping the vegetables midway through cooking but you may flip them if desired.
  2. To the canister of a Vita-Mix or blender, add the coconut milk, roasted vegetables, peanuts or peanut butter, and blend until smooth and creamy or leave this soup a bit chunkier and with some texture retained as desired. The soup is quite thick and hearty and made be thinned with additional coconut milk, vegetable stock, or a splash of water if desired; I did not thin it out because we prefer thicker soup.
  3. Taste the soup and wait five minutes before seasoning it, and if desired season to taste (The reason for waiting is because you may think it needs something but your tastebuds may adjust after a few minutes. Adding a pinch of salt and pepper to each individual’s bowl before serving also works rather than salting the whole batch). I prefer the pure flavors of carrots, peppers, coconut milk, and peanuts and didn't add any additional salt or spices, but found that 1½ tablespoons of agave balanced the smokiness of the roasted vegetables; however, season to taste.
  4. Optionally before serving, garnish with finely diced peanuts or other nuts or seeds, a dollop of peanut butter, sour cream, yogurt, finely diced red peppers or grated carrots, a drizzle of coconut milk or coconut oil, olive oil, fresh herbs, salt and pepper. Soup will keep for up to 5 days in an airtight container in the refrigerator or can be frozen for up to 3 months.

  1. This looks so creamy and delicious. I have to try making this asap. I love that it is a simple recipe, with few ingredients, but I am sure packs a HUGE flavor punch.

  2. It looks lovely but I would have added some vegetable stock as it’s more of a broth or thick sauce without.

    Your photos always look so colourful and pretty, I can see you put a lot of thought into your presentation and it’s much appreciated.

  3. Roasted red peppers are sooooo good. I love using them on top of sandwhiches. So simple, yet they add the perfect flavor.

    My favorite roasted veggie is brussels sprouts! I never like them growing up, but when I tried them as an adult, I experimented with roasting them. Wallah! They were awesome–and now I eat them about once a week.

  4. I really loveeee your photos!! You have a talent there. ;) Also love the flavours in this soup, seems so creamy and delicious!

  5. This looks fantastic Averie! Pinning!

  6. About a year ago I made a roasted carrot and pb soup… still goes down as probably my favorite thing I’ve made for my blog. And right now I happen to have all these ingredients, red pepper included, so I will be making this later today with almond butter! cannnnot wait :)

    • Omg you just jogged my memory on your soup. Blast from the past and I DO remember it, very well, now that you say this! I can’t wait to hear what you come up with for soup today and what recipe(s) you end up incorporating. LMK. Your cookies today look killer!

  7. I adore roasted carrots but I always – always! – set off my smoke detector when roasting them. I don’t know what the deal is. But it’s worth it. The combo of roasted carrots and red pepper sounds scrumptious. Peanuts, too … yum!

    • The same thing happens to me with roasted sweet potato fries. A tiny little drizzle of EVOO and a 425F oven and my house is screeching! I HATE that! I know the exact situation you have – I have it, too. Annoying.and.then.some.

  8. Oh brilliant idea roasting the carrots too. I love roasted carrots – brings out the sweetness so well. Does chili count as a soup ;-) I used to not make many soups – always associated soup with canned stuff – blah. But I love how simple and hearty they really can be – and easy!

    • I used to be the same way with you as soups, but they’er so simple and hearty and I bet this would be right up your alley b/c I know how much you love your roasted carrots, sweet potatoes and orange squash, etc and it brings out such great flavor when you roast them, yes!

  9. Roasting+Soup= Best way to eat veggies!

  10. now this is when a Vitamix comes in handy!
    roasting veggies is the best in the fall isn’t it?

  11. I love the color of this soup! Talk about a boost for the immune system with all that healthy Vitamin A going on! Super thick and delicious and EASY! I made a hearty tomato soup last night for my family. Tis the season for soups! :-)

  12. Oh I want a bowl of this right now!

    It’s sooooo cold and rainy here. This bright, beautiful soup would be much welcomed!

  13. Oh my gosh, this sounds so divine. I love the flavor combos here: carrots, red peppers, that creamy coconut milk, and salty, crunchy peanuts. I think the peanuts would be my favorite part–just enough je ne sais quoi crunch to this soup, and I imagine it plays well with the smokiness of those (gorgeous!) roasted veggies. Now I made myself hungrier.

  14. That looks really tasty and hearty to boot, I could go for a bowl of that myself for lunch an dinner!

  15. I love how thick and creamy this soup is! And the color – mesmerizing…. PS: Love your bowls!!!

  16. You always have the prettiest photos! This soup sounds delicious…
    I love reading your blog!

  17. How did you know I was just brainstorming soup recipes last night. I wrote down a list of veggies to get to make a huge batch this weekend, and was planning on making a roasted veggie soup. Carrots, peppers, cauliflower, turnips, onions, garlic, and blend. I was debating the coconut milk, but I think I’ll let that be a game time deciison. I think any veggies pureed with some veg broth are delicious!

    • I know you don’t love coconut milk but it adds this wonderful full-bodied mouthfeel and texture and quality that is just soooo good. It makes it stick to your ribs without feeling heavy if that makes sense. I know you love your soups. Can’t wait to hear what you come up with!

  18. Hi Averie!
    This looks delicious! I think I’m going to try it with some added ginger as the spice. I love the way it tastes with carrots.
    For roasted veggies, these are so simple but I adore Ina Garten’s roasted brussel sprouts. A quick, easy and healthy addition to every meal. I lower the amount of salt a bit, but otherwise they are perfect.

    I also LOVE peanut butter in pretty much anything, especially stir fry. This Thai peanut is one of the regulars at our house (and I’m pretty sure why my husband married me). Simply sub tofu for the chicken and it’s vegan (I actually prefer the tofu, but my husband vetoes it every time! I’ll convert him yet). I’ll have to vary it up and try yours next time too!

  19. Amazing! This looks so hearty and comforting! And I love the use of coconut milk in this too!

  20. It just occurred to me that I have never made roasted carrots. Which is insane because I roast just about every vegetable I can get my hands on. I have to make this!

  21. i love creamy soups in the fall. this looks fantastic!

  22. Laziness is a perfectly acceptable reason not to turn your roasting carrots! This soup looks like such an amazing, creamy, comforting bowl for fall. :)

  23. It looks so good! I think I will make it this weekend! :)

  24. This looks SO crazy good! I made a sweet potato and peanut butter soup last year and I got some straaaange looks! Oh well, people don’t know what they’re missing out on! YUM!
