Wyoming Butternut Squash Soup: The First Soup of the Season

Bowl of creamy golden soup with seeds, sage, bread, and tea

The furnace kicked on by itself last week for the first time since April, and the house smelled like scorched dust while Kimi and I looked at each other like we’d both forgotten this happens every year. That’s the real signal out here. Not a calendar — a thermostat making a decision without asking you.

Fall goes official tomorrow, for the record: the autumnal equinox lands a little after 6 p.m. Mountain time on Tuesday, September 22. Summer has about thirty-three hours left. I’m not waiting — it’s dark before we finish dinner and I’ve already scraped a windshield.

So: soup. First of the season, and in this house it isn’t a choice. My son is five and has been asking for “the orange soup” since Labor Day. He doesn’t know the phrase “butternut squash” and has no interest in learning it. He knows the color, he knows it comes with crunchy seeds on top, and he knows he gets to do the sprinkling. I’ll take it from a kid who regards most vegetables as a personal insult. It’s also a soft landing after a month of all-day projects on here — burnt ends, jars, coals. This one is a sheet pan, a pot, a blender.

Buying and Roasting the Squash

Pick it up before you buy it. You want one heavy for its size with matte, hard skin — glossy usually means picked early, and it’ll taste like nothing. Long neck, small bulb, because the neck is solid flesh and the bulb is mostly seed cavity. No soft spots, and a dry stem still attached. That one keeps for weeks on the counter.

On the local question, I’ll be as straight with you as I was about apples. Wyoming isn’t winter squash country in any commercial sense. University of Wyoming Extension is blunt that squash likes it hot — 80s and 90s — and that short-season areas are safer with summer squash, which matures faster. Butternut is at the long end: classic Waltham runs about 105 days. People here do grow it, starting transplants indoors and using black plastic or row cover to buy time on both ends, and the irrigated valleys do send local squash to farmers markets this month. Most store-bin squash came from elsewhere, and that’s fine.

The roast is the whole recipe. You can peel and cube it — I have, my knuckles remember — but halving and roasting is less work and tastes better: the cut face caramelizes and you get concentrated squash instead of watery squash. At 425°F, cut-side down, that’s roughly 40 to 55 minutes depending on size. Undercooked squash blends grainy, so give it the extra ten.

Wyoming Butternut Squash Soup

Serves 6 · Prep 20 min · Roast 40-55 min · Simmer 20 min

Ingredients

  • 1 large butternut squash, 3 to 3½ lbs
  • 2 tablespoons olive oil, plus more for the squash
  • 1 tablespoon butter
  • 1 medium yellow onion, diced
  • 1 medium carrot, chopped
  • 1 celery rib, chopped
  • 1 tart apple (Granny Smith), peeled and chopped — optional, and very good
  • 3 garlic cloves, minced
  • 1 teaspoon kosher salt, plus more to taste
  • ½ teaspoon black pepper
  • 1 teaspoon rubbed sage (or 4 fresh sage leaves)
  • ¼ teaspoon ground nutmeg
  • Pinch of cayenne
  • 4 cups chicken or vegetable broth, plus up to 1 cup more to thin
  • ½ cup heavy cream (optional)
  • 1 tablespoon maple syrup or brown sugar, to taste
  • 2 teaspoons apple cider vinegar or fresh lemon juice

How to Make It

1. Roast the squash. Heat the oven to 425°F. Halve the squash lengthwise, scoop the seeds and strings (save them), rub the cut faces with oil and salt, and set them cut-side down on a parchment-lined sheet pan. Roast 40 to 55 minutes, until a knife goes through the neck with no resistance. Cool, then scoop out the flesh.

2. Build the base. While it roasts, warm the oil and butter in a heavy pot over medium. Add the onion, carrot, and celery with a pinch of salt and cook 8 to 10 minutes, until soft and just starting to color. Don’t rush it.

3. Bloom the aromatics. Add the garlic, apple, sage, nutmeg, cayenne, salt, and pepper. Stir about a minute, until you can smell the sage.

4. Simmer. Add the roasted squash and 4 cups of broth. Break the squash up with your spoon and simmer 15 to 20 minutes, until the apple and carrot are completely tender.

5. Blend. Immersion blender straight into the pot, a full minute or two — longer than you think. You want velvet, not “mostly smooth.” Countertop blender: off the heat, half-full batches, lid vented and covered with a towel. Hot soup in a sealed blender will redecorate your ceiling.

6. Finish. Back on low. Stir in the cream if you’re using it, then the maple syrup, then the vinegar. That splash of acid is the step everybody skips and the one that makes this taste like something instead of just sweet. Thin with broth until it coats a spoon but still pours. Taste, salt, serve hot.

Toppings and Variations

  • Toasted pepitas. Rinse and dry the seeds you saved, toss with oil and salt, roast at 325°F for 12 to 15 minutes until golden. Free garnish, and the reason a five-year-old eats this.
  • Crispy sage. Fry whole leaves in butter about 30 seconds, until they stiffen and stop sizzling. Drain, then pour the browned butter over the soup too.
  • A swirl of cream. Heavy cream, thinned sour cream, or crème fraîche, dragged through with a knife tip.
  • More apple. A second one, or cider in place of a cup of the broth. The bag I bought for the Dutch oven apple crisp covered both.
  • Heat, smoke, or meat. Chipotle in adobo, chili crisp, or green chile from the freezer. Crumbled bacon or browned sausage at the end makes it the whole meal.
  • Dairy-free. Coconut milk for the cream, lime for the vinegar.

What to Serve With It

Bread, and it isn’t close. A thick slice of Dutch oven sourdough, toasted hard and buttered — you want structure to drag through it. Grilled cheese cut into strips is the kid version, and honestly the better one.

It keeps five days in the fridge and freezes for three months; leave the cream out and stir it in when you reheat. Make a double batch. By late October it’s dark at five and nobody wants to start from scratch.
