I was tempted to file this under summer food, even though acorn squash is usually associated with fall. Florida does not always follow the usual seasonal script, and a good local find is reason enough to turn on the oven. Today the squash is both the ingredient and the serving dish: a sweet little bowl filled with sausage, couscous, and a few things from the pantry.
Acorn squash (Cucurbita pepo) gets its name from its shape. Its ridged shell protects sweet, yellow-orange flesh, and although dark green is the familiar color, there are golden and variegated varieties too. It is a useful winter-storage squash when kept in a cool, dry place. In the garden it needs warm soil and a frost-free growing season, with harvest time depending on the variety and conditions. On the plate it brings fiber, potassium, and a naturally sweet flavor that works especially well with savory fillings.
For this recipe, hollowed squash halves become vessels for a simple stuffing. Most of what goes inside can come from the refrigerator and pantry. That is part of the fun.
For this recipe we will need:
- 2 acorn squashes, about 4–5 inches in diameter
- ⅓ cup couscous
- 1 sausage, preferably a sweet variety to complement the squash
- 1 teaspoon cumin
- 1 clove garlic
- 1 medium onion
- 1 pinch red pepper flakes
- 1 tablespoon olive oil
- 1 tablespoon balsamic or sherry vinegar
- A few raisins (optional)
- Salt
- Black pepper
It looks fancy, but it is simple. Feel free to change the filling to suit what you have. Couscous needs a little more thought if you replace it; I will explain why below.
Start by scrubbing the squash under running water with a clean produce brush. Dry it before cutting; do not use soap on produce.
For a large, hard vegetable, I reach for a sturdy knife and make sure the cutting board cannot slide.
Here I am using a serrated knife. The teeth help it grip the skin, but work slowly and keep your hands out of the blade’s path.
Cut off the top about an inch below the stem, making a lid for each squash.
With a smaller, sharp knife, trim a thin slice from the bottom if needed so each squash sits steadily. Keep that cut shallow; we still need a closed bowl for the stuffing.
Scoop the seeds from both the squash and its lid with a large spoon. Save the seeds for roasting if you like. Scrape out a little flesh to enlarge the cavity, and keep those pieces for the stuffing.
Set the squash on a baking pan and drizzle with a little of the olive oil. Season with salt and…
pepper, of course.
Put them in a 375°F (190°C) oven while you prepare the filling. And yes, that is an oven thermometer in the picture. I am a geek, okay?
Scrape the usable flesh from the trimmed end pieces too. In the upper-left corner of the photo you can see the squash I have saved for the filling.
Peel the onion.
Halve it lengthwise, then make radial cuts toward the center, following the green lines in the photo. This is the sort of detail that is much easier to show than to describe. Imagine the slices fanning out from the root.
Slice across those cuts to chop the onion. Here you can see the radial cuts more clearly.
Roughly chop the squash flesh you saved. It does not need to be especially fine.
Peel the garlic and slice it lengthwise.
Stack the slices, cut them into thin strips, then cut across the strips to dice. I call this the 3D cut: along the X, Y, and Z axes. Engineering follows me into the kitchen.
Slit the sausage casing and peel it away. If a little sausage sticks to it, do not worry.
You should end up with something like this. Chop or crumble the sausage.
Heat a pan over medium-high heat and add the remaining olive oil.
Add the chopped onion, garlic, and sausage, keeping the squash aside for now.
Stir as the sausage cooks and the mixture begins to brown.
Add the chopped squash and the raisins, if using.
Add the cumin and red pepper flakes, adjusting the heat to your taste.
Measure ⅓ cup of couscous and have it ready. Couscous is useful here because it cooks quickly with the moisture from the filling and squash. Rice or another grain is not a direct swap: cook it most of the way first, or it may still be hard when the squash is ready.
Take the pan off the heat and add the balsamic vinegar.
Let the residual heat soften its sharpness. We already have sweetness and spice; a little acidity brings them together. Balsamic adds sweetness of its own, which bridges the flavors nicely. Orange juice is another variation to try.
With the pan off the heat, stir in the couscous. If you choose rice instead, use rice that is already nearly cooked rather than relying on the squash to provide enough liquid to cook raw grains.
Take the squash from the oven. Its surface should be slightly wrinkled and dry, but the flesh will still need more cooking. And yes, my oven could use a cleaning.
Spoon in the filling without packing it tightly. Do not force every last bit into the squash; there will probably be some left over. Replace the lids loosely so steam can escape. Use sound, unspoiled squash rather than trying to rescue a moldy one.
Return them to the oven for about 20–30 minutes, or until the squash is tender and the center of the stuffing reaches 165°F (74°C). Meanwhile, the cook deserves a little treat.
Put any leftover filling in a pan with a splash of water, broth, or stock and finish cooking it over medium heat. Make sure the sausage is fully cooked and the couscous is tender.
A sweet, spicy couscous snack while dinner finishes in the oven. Not a bad reward.
After about 30 minutes, begin checking the squash with a fork.
Fork-tender means the fork goes through the flesh without much resistance. Check the stuffing’s temperature too, then remove the squash and let it rest briefly.
Serve warm. Try to get a little squash and a little filling in every bite. Refrigerate any leftovers promptly rather than leaving a sausage-filled squash out to cool for hours.
Do not limit yourself to this filling. Once I stuffed one squash with another squash and feta, and it was excellent. Feta’s salty bite is a wonderful match for sweet squash. But that is a completely different post.
