Long ago, in the kitchen of one of Montreal’s finest restaurants, I was taught that a truly fantastic soup can be made from a mere handful of humble ingredients.
What made the soup exceedingly good was the quality and freshness of the ingredients, and the method used for cooking. Over the long, frigid Montreal winters, we cooked batch after batch of sous vide butternut squash, and pureed them with a splash of cream for a velvety soup with vivid color. Night after night, I filled bowls with the rich potage, and topped it with delicacies such as seared foie gras, sauteed wild black trumpet mushrooms, and a pomegranate juice reduction. Sublime.
Today’s recipe is inspired by those upscale bowls of soup: a simple combination of apple, squash and onion, seasoned with salt, and thinned with a little cream. Garnished with diced apples, it’s fall in a bowl; and yes, it was cooked sous vide.
Now, I’m a fan of simple soup from scratch, and will be the first to admit that a sharp knife and a sturdy pot are the only requirements for a good soup, be it rustic, roasted or rich. Alternately, I also have enough of a background in professional cooking to know that ingredients slowly cooked in a water oven (or sous vide) will yield a superior soup.
Ten years ago, when I was manning the stove in various restaurants, the culinary term ‘sous vide’ was virtually unknown to anyone outside of processionals. Now, thanks to crazy-popular TV shows such as Top Chef, Master Chef, and Iron Chef, sous vide is fast gaining on culinary terms such as ‘braising’ or ‘searing’. There are even cookbooks devoted to the subject such as Under Pressure: Cooking Sous Vide and Sous Vide: Help for the Busy Cook.
When the kind folks behind Sous Vide Supreme contacted me to try one of their counter top water ovens, I agreed, as I was eager to see this beautiful new home version for myself. It has been really fun to recreate some of the recipes for my family I had tucked away from my restaurant days.
Danny, armed with his copy of Cooking for Geeks, is pretty excited to get into sous vide cooking. Being our resident numbers guy, he of course loves the science behind the sous vide method and I’m more than happy to let him share the kitchen.
I can see the sous vide supreme working out very well for our family thanks to my background and Danny’s obsession with temperature. We’ll keep you posted.
What is ‘sous vide’? It means to cook food in vacuum-sealed pouches, submerged in a water bath held at a precisely controlled temperature. Sous vide means “under vacuum” in French, as you can see from the images above. The first photo is before cooking, the second is after. (There’s a helpful video on the Sous Vide Supreme website that explains the cooking method with a great visual.)
What makes a sous vide soup superior? When cooked slowly, in a water bath, vegetables and fruits retain their full color and flavor as well as undergo a remarkable transformation in texture. Once pureed, the flavors seem intensified, and the resulting texture is soft and velvety. With just one bite of this soup, Danny was smitten.

Ingredients
1mediumbutternut squashpeeled and sliced
1largetart applesuch as Granny Smith, cored and sliced
1/2onionsliced, or 6 green onions, ends trimmed
1teaspoonsea salt
3/4cuplight cream
Instructions
Fill 2/3 full with water and preheat the sous vide unit to between 182 and 185 degrees F.
Place the sliced squash, apple and onion into a large, one-gallon food-grade pouch. Vacuum seal the bag to remove as much air as possible.
Submerge the pouch in the sous vide unit and cook for 2 hours until the squash and apples are quite soft. Check the pouches after 20 minutes to make sure they’re fully submerged. If they are floating, weigh them down with a mug or other heavy object.
When the squash is cooked, remove the pouch from the Supreme, and pour the contents into a blender. Puree until smooth.
Add sea salt and cream and puree again. Taste and add more salt if you like. Serve hot, garnished with diced apple if desired.
I use ground sage and nutmeg which both enhance the flavors of butternut squash and bring out its natural sweetness. Stir in full-fat coconut milk to make this soup extra-creamy, and don't forget the salt and pepper!
The squash also retains most of its nutrients when it is steamed and has a wonderfully sweet butternuttiness to it. Steamed butternut can also be used in a variety of ways – added to salads, mashed, puréed or enjoyed as is with a simple seasoning of your choice.
Yellow onion and garlic – These veggies add delicious depth of flavor. Fresh sage and rosemary – I don't reach for rosemary as often as some other fresh herbs, but I absolutely love it here. Along with the sage, it makes this soup cozy and complex.
In a large bowl mix the cubed squash, garlic cloves and ginger with 2 tablespoons of olive oil and 1 tablespoon of the spice mix. Season with salt and pepper and scatter in a single layer in a roasting tray. Place in the preheated oven and cook for 30 minutes until tender all the way through.
Butternut squash contains considerable amounts of fiber, which can help you keep a healthy weight and regulate bowel movements. It's known to help prevent colorectal cancer while the beta-carotene in butternut squash can also improve eye health.
Generally, butternut squash is safe to feed to most pooches, unless your vet has advised otherwise. As a guide, we would recommend feeding small dogs no more than 1 or 2 teaspoons of butternut squash, whilst bigger dogs can eat up to 3 or 4 tablespoons of butternut squash.
More than likely, the bitterness developed in the squash as it was growing due to a lack of good growing conditions or nutrients. If you feel like the soup is better, you may be able to add in a few spices to help with the taste or you may have to try again with a different butternut squash soup.
Butternut squash contains a type of fiber that's not digestible. If you have diabetes, it can help keep your blood sugar from rising after eating. Butternut squash also has a low glycemic index, which means that its carbs are digested more slowly. This also helps keep blood sugar from rising.
For a medium sized squash, I'd recommend 1 to 2 tablespoons oil, ¼ -½ teaspoon salt, and ⅛ -¼ teaspoon black pepper. Make sure all of the squash is coated with oil. Place in oven and roast for 25 to 30 minutes, stirring once, or until squash is golden brown and fork tender. Don't overcook it or it will get mushy.
Skip eating most hard-skinned squash raw. "Hard skinned squash is difficult to eat raw," Marz says. "They are usually much larger in size, have a harder flesh, and are much more fibrous." Examples of hard-skinned squash that should not be eaten raw include: pumpkins, delicate, butternut, Hubbard, and acorn.
Add a splash of vinegar (any kind!), or a squeeze of citrus. Chances are, you could use a little more salt. Go ahead—it's ok. Salt perks up flat flavors and helps balance out bitter-tasting ingredients.
If you pick too early, the flesh will not be fully developed and the squash will lack flavor and not be that wonderfully vegetal sweet that is the wonder of butternut, honeynut, delicata, acorn, pumpkin and kabocha, among dozens of other winter squash.
Foods that have a great deal of acidity, like lemon juice, vinegar, white wine, and tomato puree, can help liven up the flavor of bland-tasting bone and other broths. "The acidity of these ingredients works to complement and enhance the broth's flavors, not mask it.
If a soup is tasting bland in the bowl, consider adding acid rather than salt. A squeeze of lemon or lime, or a dash of yogurt or sour cream can add brightness to the bowl. Our Lemony Chicken Soup will make your mouth water.
