Butternut Squash Broccoli Cheddar Soup

Featured in: Family Favorites

This comforting soup starts with oven-roasted butternut squash and broccoli, which develop deep, caramelized flavors at 425°F. After roasting, the vegetables join sautéed onions and garlic in a pot with vegetable broth, where smoked paprika adds subtle warmth. An immersion blender creates a silky smooth base before whole milk and sharp cheddar cheese are stirred in, resulting in a velvety, rich texture. The entire process takes about an hour, with most of that time being hands-off roasting.

The soup balances sweetness from the roasted squash with sharp cheddar's tang, while smoked paprika and optional cayenne provide gentle heat. It's naturally gluten-free and can easily be made vegan with plant-based milk and vegan cheese. Serve with crusty bread for dipping or a crisp green salad to round out the meal.

The aroma of butternut squash caramelizing in my oven on a crisp autumn afternoon always transports me to that memorable weekend when I first created this soup. My kitchen window was fogged with steam, rain tapping gently outside, as I experimented with combining roasted butternut and broccoli into something that would warm us from the inside out. What began as a desperate attempt to use up vegetables before they spoiled turned into a silky, cheese-enriched comfort that has graced our table ever since.

Last winter when my neighbors lost power during that terrible ice storm, I invited them over and ladled this vibrant orange soup into mismatched mugs we could cradle with cold hands. We huddled around my kitchen island, steam rising from our cups, everyone momentarily forgetting their frozen pipes and darkened homes. Someone commented that the color alone was like bottled sunshine, and in that moment, I understood how food becomes more than sustenance.

Ingredients

  • Butternut squash: Look for one with a matte rather than glossy skin, which tells you its properly ripened and will give you that sweet, nutty flavor that makes this soup special.
  • Broccoli: Dont discard those stems, they add wonderful texture and nutrition when peeled and diced small enough to roast evenly with the florets.
  • Sharp cheddar cheese: I learned after multiple attempts that pre-shredded varieties often contain anti-caking agents that prevent it from melting smoothly, so grating your own block makes a noticeable difference in silkiness.
  • Smoked paprika: The subtle smokiness balances the sweetness of the squash without overpowering the delicate flavor balance.
  • Vegetable broth: Choose a low-sodium version so you can control the saltiness yourself, adjusting it to complement the natural sweetness of the roasted vegetables.

Prep your vegetables:
Peeling butternut squash can be tricky, so use a sharp vegetable peeler and work from the neck down toward the bulbous end. Youll know youve cut the broccoli florets properly when theyre about the same size as your squash cubes, ensuring even roasting.
Roast to golden perfection:
Listen for that gentle sizzle when you spread your vegetables on the hot baking sheet, a sound that promises the caramelization that transforms ordinary vegetables into something magnificent. The kitchen will fill with a nutty aroma about 20 minutes in, but resist checking too early.
Build the flavor base:
The butter and onion mixture should smell sweet rather than sharp when the onions are perfectly translucent. Add the garlic just until fragrant to avoid any bitterness.
Blend with care:
If using an immersion blender, keep it slightly submerged to prevent splattering hot soup everywhere, a lesson I learned the hard way while wearing a white shirt. For a countertop blender, never fill more than halfway and always cover with a kitchen towel while holding the lid firmly.
Add the dairy with patience:
Reduce the heat before adding milk and cheese, stirring constantly in a figure-eight motion to encourage even melting. The transformation happens gradually, so dont rush this final step that brings everything together.

My daughter, who historically declared all orange foods suspicious, stood in the kitchen doorway watching me make this soup one evening. She reluctantly accepted a small taste from a spoon I held out, then promptly fetched her own bowl and asked for seconds before finishing the first. Now she requests it when friends come over, proudly explaining how the roasting makes all the difference, as if revealing a culinary secret passed through generations.

Make-Ahead Magic

Sunday meal prep becomes a gift to my future self when I double this recipe and freeze portions in mason jars, leaving an inch of headspace for expansion. The soup actually develops deeper flavor after a day in the refrigerator, making it perfect for planning ahead. Ive found it keeps beautifully for three months in the freezer without any compromise in texture or taste, especially when reheated slowly over low heat rather than blasted in the microwave.

Seasonal Adaptations

Summer brings a lightened version to our table, where I substitute half the butternut squash with yellow summer squash and add fresh basil at the end. In deepest winter, I sometimes add a diced apple to the roasting pan, its sweetness intensifying alongside the squash. The spring variation includes tender asparagus tips added just before blending, their bright flavor cutting through the richness and reminding us that warmer days are coming.

Serving Suggestions

The presentation of this soup elevates an ordinary weeknight dinner to something that feels intentional and celebratory. My cast iron skillet cornbread with honey butter makes a perfect companion, the slightly sweet crumbliness offering textural contrast to the smooth soup.

  • For unexpected crunch, top each bowl with pepitas or sunflower seeds toasted quickly in a dry pan until they pop and become fragrant.
  • A small drizzle of good olive oil creates beautiful golden pools on the surface that carry additional flavor with each spoonful.
  • Keep some extra roasted broccoli florets aside before blending to float atop each serving, giving visual interest and something substantial to discover.

This soup has taught me that sometimes the most nurturing things we create come from simple ingredients transformed with a little patience and attention. In a world of complexity, theres profound comfort in a bowl of something made with care, meant to be shared.

Recipe Q&A

Can I make this soup ahead of time?

Yes, this soup reheats beautifully. Store in an airtight container in the refrigerator for up to 4 days. Reheat gently over medium-low heat, stirring occasionally to prevent separating. You may need to add a splash of milk or broth when reheating to restore the creamy consistency.

Can I freeze this soup?

The soup freezes well for up to 3 months. Cool completely before transferring to freezer-safe containers. Thaw overnight in the refrigerator, then reheat gently. Note that the texture may be slightly thinner after freezing, but a quick blend will restore creaminess.

What can I use instead of cheddar cheese?

Gruyère, Swiss, or fontina work beautifully for a different flavor profile. For a dairy-free version, use vegan cheddar shreds or nutritional yeast for cheesy flavor. The key is choosing a cheese that melts smoothly for the creamiest texture.

Do I have to roast the vegetables first?

Roasting concentrates the natural sugars and adds depth, but you can skip it for a quicker version. Sauté the squash and broccoli with the onions until softened, then proceed with the broth. The soup will still be delicious, though slightly less complex in flavor.

How can I make this soup thicker?

For extra thickness, add a peeled potato during roasting or blend in a cup of cooked white beans. Reducing the water by half cup also creates a heartier consistency. Alternatively, let the soup simmer uncovered for 5-10 minutes longer to reduce and thicken naturally.

Is this soup suitable for meal prep?

Absolutely. The flavors actually deepen after a day or two in the refrigerator. Portion into individual containers for easy lunches throughout the week. Add garnishes like extra cheese or roasted broccoli just before serving to keep them fresh.
