The Ingredients and Substitutes
Recipe Variations
Make this butternut squash and roasted red pepper soup recipe your own with:
- White miso paste: A tablespoon of miso adds salty, sweet, umami-rich depth for a more complex butternut red pepper soup.
- Spices: Like smoked paprika, cinnamon, and/or ginger (minced/powdered). Add heat with cayenne, chili powder, or red pepper flakes. You can also make butternut squash and chili soup with fresh red chilies.
- More vegetables: Add depth with sweet potato, carrot, or parsnip.
- Beans: For extra fiber and protein. Like cannellini beans, butter beans, or chickpeas blended into the soup or left whole.
- A different twist: Flavor the butternut squash and pepper soup with turmeric, cumin, and garam masala instead of Italian seasoning and basil.
- Apple/pear: Roast a chopped apple or pear with the veg to add sweetness.
- Garnishes: i.e., croutons, crispy chickpeas, kale chips, fresh herbs/microgreens, toasted sunflower/pumpkin seeds/ pine nuts, chili flakes, swirl of vegan cream, etc.
How to Make Roasted Butternut Squash Red Pepper Soup
Keep scrolling to the recipe card for the complete list of ingredients and recipe instructions.
Step 1: First, preheat the oven to 400F/200C and peel the garlic and onion, then roughly chop the latter. Also, de-seed and slice the bell peppers into thick wedges and peel and chop the butternut squash into ½-inch cubes/slices.
- To chop butternut squash: First, cut off both ends, then chop it in half lengthwise and use a spoon to scoop out the seeds. Then, peel both halves, slice them into ½-inch strips, then into cubes. Alternatively, roast the butternut squash in halves.
Step 2: Spread the vegetables across a parchment-lined baking sheet, drizzle with olive oil, salt, and pepper, then toss. Mix and roast for 30-40 minutes or until tender.
Step 3: Meanwhile, prepare the veg bouillon and water mixture (or heat the veg broth), stir in the Italian seasoning, and set aside.
Step 4: Transfer the roasted vegetables, broth, silken tofu, and basil to a blender and blend until smooth and creamy (about 2 minutes).
- Step 5: If the butternut squash roasted red pepper soup isn’t hot enough, optionally pour it into a saucepan to heat over low. Enjoy!
FAQs
Do I have to peel the roasted red peppers?
We’ve never felt it necessary since my high-speed blender will pulverize them. However, if you prefer, you can peel them post-roasting.
Can I use a stick blender?
Technically, yes, though it may not produce a soup as smooth and creamy.
Is Roasted Red Pepper and Butternut Squash Soup Healthy?
Along with being delicious, butternut squash soup with roasted red pepper is super nutritious and packed with fiber, healthy fats, plant-based protein, vitamins, minerals, and antioxidants.
Butternut squash alone is loaded with vitamin A (beta-carotene), vitamin C, vitamin E, several B vitamins, magnesium, potassium, and manganese, as well as several antioxidants, including carotenoids.
Red bell peppers are another rich source of vitamin C, with moderate levels of vitamins A, E, potassium, folate, and more. They’re also rich in carotenoids, like beta-carotene and lutein.
The combination of nutrients is beneficial for your immune system, eye health, skin health, and bone health, as well as reducing the risk of certain cancers.
Pro Recipe Notes
- For thicker/thinner soup: Adjust how much liquid you add to the soup.
- To save prep time: Feel free to use pre-chopped butternut squash and/or pre-prepared ingredients like chopped onion, peeled garlic cloves, etc.
- Be careful when blending: The hot ingredients cause steam to build up in the blender, so it’s best to pause the machine and open the lid to release steam so it doesn’t blow off and send scalding liquid flying.
Serving Recommendations
- Bread – i.e., crusty bread, garlic bread, focaccia, or fluffy roll for dipping.
- Sandwiches/wraps – Like a vegan mushroom sandwich, pesto tofu sandwich, or even a vegan grilled cheese.
- A side salad—like a garden salad, vegan Caesar salad, shredded Brussels sprout salad, or roasted beet salad.
Storage Instructions
Leave the roasted red pepper butternut squash soup to cool, then store leftovers in an airtight container in the refrigerator for 4-5 days.
Alternatively, freeze it in freezer-safe bags (spread flat) or containers for up to 3 months. Then, leave it to thaw in the fridge overnight before reheating.
Reheat the soup on the stovetop (over medium-low heat) or in a microwave (1-2 minutes). Add an extra splash of water or stock if preferred.
