Roasted Broccoli Butternut Squash Soup

Featured in: Comfort Food Essentials

This velvety soup combines the natural sweetness of roasted butternut squash with earthy broccoli florets, roasted at high heat to develop deep caramelized flavors. After roasting with onion and garlic, the vegetables are simmered in vegetable broth before being pureed into a silky, smooth texture. Coconut milk or cream adds richness, while nutmeg and cumin provide warm spice notes that complement the roasted vegetables perfectly.

The warm, earthy aroma of roasting vegetables always turns my kitchen into a sanctuary on chilly afternoons. I discovered this broccoli and butternut squash soup recipe during a particularly cold autumn when the farmers market was overflowing with squash varieties. My first attempt was actually a happy accident – I'd planned to make two separate vegetable sides, but ended up combining them when dinner plans changed. The resulting soup was so silky and complex that it immediately earned a permanent spot in my recipe collection.

Last winter, I made this soup when my sister came to visit with her kids. The kitchen windows fogged up as the vegetables roasted and the little ones kept asking what smelled so good. Even my nephew, who famously hates anything green, asked for seconds that night. We sat around the table dipping crusty bread into our bowls, and for once, dinner wasnt a battlefield of negotiating with picky eaters.

Ingredients

  • Butternut squash: Look for one with a matte skin without soft spots – the heavier it feels for its size, the more flavor-packed it will be.
  • Broccoli: Dont discard those stems, they add incredible sweetness when roasted properly.
  • Coconut milk: The slight tropical note creates this magical balance with the earthy vegetables that changed everything for me.
  • Cumin: Just that half teaspoon transforms the flavor from basic vegetable soup to something that makes people wonder about your secret ingredient.

Prep your vegetables:
Peeling and cubing butternut squash can be a workout, so make sure your peeler is sharp. I like to microwave the whole squash for about 3 minutes first to soften the skin slightly.
Season generously:
Dont be shy with the salt when roasting – it draws out moisture and concentrates flavors. The vegetables will shrink as they roast, so what looks like too much seasoning initially will be just right.
Get that perfect roast:
Spread everything in a single layer, giving the vegetables breathing room. Overcrowding leads to steaming instead of that caramelized goodness we want.
Blend with care:
If using a countertop blender, work in batches and never fill more than halfway with hot liquid. I learned this the hard way when I created what I now refer to as The Great Kitchen Ceiling Repainting of 2019.
Taste and adjust:
Soups always need a final seasoning check after blending. Sometimes I add an extra pinch of salt or nutmeg right at the end to make the flavors pop.

The soup became our unofficial holiday gathering starter last year after my mother-in-law requested it specifically. Id never seen her ask for seconds of anything Id made before, but she actually took the leftovers home in a container shed brought just in case. That silent vote of confidence meant more to me than any verbal compliment could have.

Make-Ahead Tips

This soup actually improves with time as the flavors meld together in the refrigerator. Ive learned to make it a day before I need it, which not only tastes better but takes the pressure off when hosting. The soup keeps beautifully for up to four days refrigerated, and Ive found it freezes exceptionally well in individual portions for up to three months – perfect for those nights when cooking from scratch feels impossible.

Customization Options

While the basic recipe is fantastic, Ive created several variations over time. For a protein boost, white beans blend seamlessly into the soup. Curry powder instead of cumin and nutmeg gives it an entirely different personality. When Im feeling fancy, a swirl of browned butter and crispy sage leaves on top transforms it into something restaurant-worthy without much extra effort.

Serving Suggestions

The right accompaniments can elevate this soup from a starter to a complete meal. I discovered this when unexpected dinner guests arrived and I needed to stretch what I had prepared.

  • A simple arugula salad with lemon vinaigrette provides a bright, peppery contrast to the creamy soup.
  • Toasted sourdough rubbed with garlic creates the perfect vehicle for scooping up every last drop.
  • For special occasions, crispy prosciutto or bacon crumbles add a salty crunch that even committed vegetarians might be tempted by.

Recipe FAQs

Can I make this soup ahead of time?

Yes, this soup reheats beautifully. Prepare it up to 3 days in advance and store in an airtight container in the refrigerator. Reheat gently over medium-low heat, stirring occasionally, until warmed through.

Can I freeze this soup?

Absolutely. Let the soup cool completely before transferring to freezer-safe containers. It will keep well for up to 3 months. Thaw overnight in the refrigerator before reheating.

What can I use instead of coconut milk?

Heavy cream creates an even richer soup. For a dairy-free option, you can use cashew cream, almond milk, or simply omit the creamy element and add more broth for a lighter version.

Do I have to roast the vegetables first?

Roasting is essential for the best flavor depth. The high heat caramelizes the natural sugars in the squash and broccoli, creating a much more complex taste than simply boiling the vegetables.

How do I get the smoothest texture?

An immersion blender works well, but a high-speed countertop blender yields the silkiest results. Blend in batches if using a standard blender, and be careful with hot liquids—vent the blender slightly to release steam.

Can I add protein to this soup?

Yes, stir in white beans, lentils, or shredded chicken during the last 10 minutes of simmering. You can also serve with grilled cheese or pair with roasted chickpeas as a topping.
