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.
