Roasted Butternut Squash with Brown Butter and Sage
Not rated yet. Be the first.
Squash cubes roast until the edges go dark and sweet, then sage crisped in brown butter and a spoon of maple finish them. The kitchen smells like the first cold night of fall.
The short version
Peel and cube two butternut squash, toss with oil and salt, and roast on two sheet pans at 425°F for 35 to 45 minutes, until deeply browned. Finish with sage fried in brown butter and a spoon of maple. Don't crowd the pans.
What makes ours better
what we fixed so you don’t have to
-
Split the neck from the bulb before you peel. Two flat-bottomed pieces stand still on the board, so the knife and peeler never slip. Peel until no pale green streaks remain; that layer stays tough after roasting.
-
High heat and two pans. At 425°F with space between the cubes, moisture escapes and the sugars brown. Crowd one pan and the squash steams in its own water and comes out soft and pale.
-
Brown butter, sage and maple at the end. Maple burns in a hot oven and sage turns bitter, so both go on after roasting. Sage leaves fried in brown butter turn crisp in a minute, and the nutty butter with a little maple tastes like the squash's sweetness turned up.

Steps
deep breath. you’ve got this.
-
Heat the oven
Set racks in the upper and lower thirds of the oven and heat it to 425°F. Line two rimmed baking sheets with parchment.
-
Split and peel the squash
Cut off the stem and the base of each squash so it has two flat ends. Stand it up and cut across where the narrow neck meets the round bulb. Stand each piece on its flat end and run a sharp Y-peeler or a chef's knife down the sides, turning as you go, until the flesh is bright orange with no pale green streaks.
Always cut with a flat side down. A squash that rolls is how fingers get hurt.
-
Seed and cube
Halve the bulb pieces through the top and scoop out the seeds and strings with a sturdy spoon. Cut everything into 1-inch slabs, then into 1-inch cubes. Keep them even so they cook at the same rate.
-
Season and spread out
Divide the cubes between the two pans, drizzle with the oil, sprinkle with the salt and pepper and toss with your hands. Spread them in a single layer with a little space between pieces.
-
Roast until browned
Roast for 20 minutes without touching them. Flip the cubes with a thin metal spatula, swap the pans between racks and roast until the squash is tender all the way through and deeply browned on several sides, 15 to 25 minutes more.
Don't stir early. The cubes need time against the hot pan to brown and release on their own.
About 20 min. Cook mode has a timer for this step.
-
Brown the butter with sage
In the last few minutes, melt the butter in a light-colored skillet over medium heat. When it foams, add the sage leaves and swirl the pan. In 2 to 3 minutes the leaves will turn crisp and darker green, and the butter will smell nutty and show brown specks at the bottom. Take it off the heat and lift out the sage onto a plate. Stir the maple syrup into the butter.
About 3 min. Cook mode has a timer for this step.
-
Finish and serve
Pile the squash into a serving dish, pour the maple brown butter over it and toss gently. Crumble the crisp sage over the top, sprinkle with flaky salt and serve warm.
Good to know
things I learned the hard way, so you can skip that part
- If your squash is very hard to cut, pierce the skin a few times with a fork and microwave it whole for 2 to 3 minutes. The skin softens and the knife goes through more easily. Let it cool enough to handle.
- For a savory version, skip the maple and finish with a squeeze of lemon and grated Parmesan. For heat, add a pinch of red pepper flakes to the brown butter.
- To make it ahead, roast the squash up to 2 days early and refrigerate. Reheat on a sheet pan at 425°F for 10 minutes, then make the brown butter and finish.
- Pre-cut squash from the store works; cut any big chunks down to 1 inch and use about 4½ pounds.
- Storage. Refrigerated, covered, 4 days. Reheat on a sheet pan at 400°F for 8 to 10 minutes so it stays firm. Frozen, 3 months; it turns soft, so use frozen leftovers for soup or mash.
Questions, answered
the questions my cousins text me
How do I peel butternut squash without hurting myself?
Trim both ends, cut the neck from the bulb, and stand each piece on a flat cut side before peeling with a Y-peeler or knife. Never peel or cut a squash that can roll.
What temperature should I roast butternut squash at?
425°F. Lower temperatures cook it through but don't brown it, and you'll get soft, pale cubes.
How long does it take to roast butternut squash cubes?
1-inch cubes take 35 to 45 minutes at 425°F. They're done when a fork slides in easily and several sides are deep golden brown.
Why is my roasted squash mushy?
The pan was too crowded, so the squash steamed. Use two pans and leave space between the cubes. Cutting the pieces smaller than 1 inch makes it worse too.
Do I have to peel butternut squash before roasting?
For cubes, yes. The skin is edible but stays chewy. If you roast halves or thin slices, you can leave it on.
