How to Make Roasted Red Pepper and Tomato Basil Bisque

You might be wondering how a bisque can be creamy without dairy. The secret? Cauliflower!! This versatile veggie not only adds nutrition but also makes the soup perfectly creamy and silky. Trust me, if you’re unsure about cauliflower, you won’t even notice. It blends seamlessly into the soup. As a nutritionist, I love recipes that sneak in extra veggies while keeping the taste amazing. My family had no idea this bisque was dairy-free!!

Step 1: Roast the Veggies

Preheat your oven to 400 degrees. Slice the red bell peppers in half, remove stems and seeds, and lightly brush with oil. Toss the tomatoes in a little oil as well. Place the peppers and tomatoes on a baking sheet and roast for 25 minutes or until slightly blistered and golden on top.

Step 2: Saute the Base

While the veggies roast, heat a large soup pot over medium heat. Add a tablespoon of oil, then sauté diced onion for 3-4 minutes. Add minced garlic and cook another 2 minutes. Toss in chopped cauliflower and cook briefly.
Step 3: Simmer

Pour in the vegetable or chicken broth and bring to a boil. Reduce heat to a simmer and cook until the cauliflower is tender, about 10 minutes. Add roasted peppers, tomatoes, and a pinch of sea salt to the pot.
Step 4: Blend Until Creamy

Add fresh basil to the soup. Use an immersion blender or a regular blender to puree until smooth and creamy. Taste and adjust seasoning as needed.
Step 5: Serve and Enjoy

Garnish with fresh basil if desired and serve hot!! This bisque is delicious on its own, but you can also add cooked shrimp, chicken, or sausage for extra protein if you like. It keeps well in the fridge for up to a week, making it perfect for meal prep.

    This recipe sounds amazing, however it wouldn’t technically be a Bisque. Because Bisque, when not referring to the traditional French seafood soup that is made from strained crustaceans, i.e. lobster, langoustine (scampi), shrimp, crab or crawfish, sautéed in their shells, is specifically made from pre-cooked puréed ingredients that are mixed with heavy cream or whole milk in order to produce a rich, creamy soup. When made with broth or stock, it’s simply a soup. Some traditionalist argue that Tomato Bisque isn’t technically a true bisque at all because it is not made with nor does it have any crustaceans in it. However the term “bisque” has evolved in modern days to also refer to cream-based soups. So basically, broth and stock equals soup and cream or whole milk equals bisque.

    THIS WAS AMAZING!
    We loved this recipe and will definitely make it again. And the fact that I could make it vegan was really great. Thank you so much.

    This sounds amazing! I’ve got picky kids who love tomato soup, but would likely sniff out the red pepper and refuse to eat it. ???? If I were to drop down to one or one and a half bell pepper, would you increase the tomato by 1 or 2 cups?

      I would increase by 2 cups to help balance out!
