Roasted Butternut Soup is an easy, healthy recipe with a great tasting flavor, thanks in part, to the miracles of caramelization.
It’s equally simple to make, thanks to the availability of pre-peeled and diced butternut squash from your local grocery store. Read on and I’ll show you how to make this, it’s one of my favorite ways to use butternut squash.
About this recipe
If you’ve ever wondered how to peel butternut squash, I’ve found the most convenient method is to stop by your nearest Costco where you can buy a pound or two of it sliced, diced, and ready to go.
I’m not the neatest guy in the kitchen and lining a baking sheet with parchment paper helps make clean-up easier.
Once you have the butternut squash in a single layer on the baking sheet, use a paper towel to blot it dry. Doing so will enhance the caramelization process.
What is caramelization?
What is caramelization anyhow?
In short, caramelization is the browning process that brings out the sugars and other flavors in foods that are roasted or browned using some other method such as searing.
After you have blotted the butternut squash with a paper towel, you’re going to get wet again, but this time with some healthy extra virgin olive oil.
Then, you’ll toss in a pinch or two of kosher salt, some fresh ground black pepper, and finally some fresh thyme leaves.
Make the Mirepoix
There’s that word again: Mirepoix.
We’ve made so many mirepoix here on Platter Talk that if we had another kid, we would probably name them Mirepoix.
We use a mirepoix in our:
- Braised Beef
- Winter Garden Vegetable Soup
- Pork Shoulder
- Sausage and Chicken Gumbo
- Braised Garlic Chicken
A mirepoix is simply a flavor base that is made from sauteeing diced vegetables, usually in butter, oil, or some other fat.
When making a mirepoix for the flavor base of your dish, use the classic ingredients listed above.
Or, improvise and make your own mirepoix using other aromatics such as garlic, leeks, and other fresh ingredients like bell peppers and mushrooms.
If you want to add some extra flavor and sweetness to your mirepoix, saute the carrots until they are a soft, caramel color.
This will take about 10 minutes over medium-low heat.
Also, I love to use rainbow carrots for extra depth and color!
After the carrots are soft and ever-so-slightly “tanned,” I add the other ingredients to my mirepoix.
When the butternut squash is soft and starting to get that brown, caramelized color, it’s time to add it to the mirepoix. Then add some warm broth.
Right about now is when people from all over our little house will start to drift into the kitchen.
From the playroom in the basement, from the living room, from the bedrooms, from all over, the kids all gravitate to the stovetop and ask, “Dad, what smells so good?”
I admit that’s always music to my aging ears.
If you have an immersion blender, it’s a good way to blend the ingredients to your desired consistency.
If you don’t have an immersion blender, carefully transfer the soup to a blender and blend away.
Just be super careful not to burn yourself.
I learned that my kids like a creamy consistency with this butternut squash soup, while I prefer a little more texture.
