This soup started life as a proper kitchen rescue. It was a rainy evening in Bristol, Ellie was ravenous and I had one lonely butternut on the counter and an 8 ounce block of feta in the fridge. I shoved everything into a pot and hoped for the best. It turned out brilliant. The roasted squash gets sweet and a bit caramelized, the feta melts into a tangy cream and the whole thing feels like a warm jumper on a damp day.
If you are wondering what to do with butternut squash that has been sitting around, this is your answer. This baked feta soup with squash is easy, forgiving and very family friendly. My husband went very quiet while he ate and then said something about how comforting it was, which is the highest praise in our house.
It is vegetarian, it fills the kitchen with cosy sage and garlic aroma, and it is surprisingly fast to pull together. So cosy.
Preheat the oven to 400 °F.
In a Dutch oven fitted with a lid, add ⅓ cup extra-virgin olive oil, 5 cups butternut squash, ¼ teaspoon kosher salt and toss to coat. Place 1 feta chunk in the center, add 4 leaves sage, and nestle the bulb of garlic in the pot. Add freshly ground black pepper to taste.
Bake, covered, until the butternut squash is soft and caramelized, about 45 minutes to 1 hour.
Using oven mitts, carefully remove the pot from the oven and take out the roasted garlic bulb. Carefully squeeze the roasted garlic cloves out into the pot and add in 4 cups vegetable broth and 2 tablespoons honey.
Use an immersion blender to puréе the soup until smooth. Taste and adjust salt and black pepper if needed.
Serve hot, drizzled with more honey and an extra sprinkle of freshly ground black pepper. Enjoy!
Start with a decent heavy pot that can go in the oven with a lid. My beat up Le Creuset is ancient but it still does the job and does not complain. If your pot is not oven safe, use a baking dish instead and transfer the roast to a saucepan later. You will want a sharp knife and a sturdy cutting board for the squash. Peeling and cubing it is the fiddliest bit, so a good blade saves time and temper. Oven mitts are non negotiable when you are pulling anything hot out of the oven.
For pureeing, an immersion blender is my absolute hero. It lets you blend right in the pot with minimal fuss. If you do not have one, a regular blender works fine as long as you cool the soup a little and blend in batches so steam can escape. I once blended a whole pot at once and learnt the hard way, so do not be me.
Wooden spoon, measuring cup for the broth, and a small bowl for the roasted garlic all help. Actually, scratch that. You can squeeze the garlic straight into the pot if you are feeling bold, but the bowl catches any messy bits.
I always roast at 400 degrees Fahrenheit because that heat gives you those lovely caramelized bits on the squash that basically scream autumn is here. The trick is that high heat concentrates the squash natural sugars so you get sweetness without having to add much else. Coat the squash well in olive oil and a pinch of kosher salt so it browns nicely rather than steams.
Roast a head of garlic with the squash. It softens into a sweet, mellow paste that blends into the soup without the sharp bite of raw garlic. Add fresh sage leaves while it roasts if you have them. Dried sage works in a pinch, but fresh lifts the pot in a way that always makes me smile.
If you want immersion blender butternut squash soup, puree directly in the pot to keep everything smooth and cut down on washing up. Taste after blending and adjust salt and pepper. I usually add a spoonful of honey at the end to balance the feta tang. The soup forgives mistakes. Over roast it a touch and add a splash more broth and it is fine.
A Little Heat Add chili flakes or a small diced jalapeno to the roasting tray so the spice can mellow in the oven. Or stir in smoked paprika for a gentle smoke note. I tried the jalapeno once when the adults wanted more kick and it worked well but keep it light if you are serving kids.
Greener Version Stir in a handful of spinach or kale after roasting and puree. The butternut hides the veg taste nicely so it is a good trick for fussy eaters. It still counts as a vegetarian soup for fall and it sneaks in extra goodness.
Luxe Finish For a richer bowl, swirl in a little double cream after blending. Add it at the end so it does not split and you will get a silkier mouthfeel. It is indulgent but lovely for guests.
This soup is happy on its own or with a chunk of crusty bread for dunking. A simple apple and walnut salad cuts through the richness nicely, and extra crumbled feta on top gives little salty pops. Pumpkin seeds add crunch and a tiny drizzle of honey on each bowl is magic.
I have served it with grilled cheese for a weekend lunch and with carrot sticks for dipping when Ellie eats with us. Once I odd paired it with popcorn and I will not lie, the salty popcorn worked surprisingly well. Small experiments are encouraged.
Short version: roast the squash and garlic, add feta and sage in the pot, pour in broth, squeeze in the roasted garlic and blend. If you want more detail, follow the cooking steps on the page. I often eyeball the broth amount depending on how watery the squash was, so the soup thickness is flexible.
Use frozen butternut squash cubes. They save you the peeling and chopping and roast very well. I call it my cheat when life is busy and it works every time. You may need an extra few minutes in the oven but otherwise the results are the same.
Yes. Cool the soup slightly, blend in batches with the lid vented, and return it to the pot. It is a bit messier but gets you the same silky texture.
Add a can of drained chickpeas or white beans before blending. They thicken the soup and add substance so you get a heartier bowl that still feels like a vegetarian soup for fall.
Absolutely. It stores well in the fridge for up to four days and freezes nicely. Reheat gently with a splash of broth to bring back the creaminess. It often tastes even better the next day as the flavours settle.
