Do I really not have to peel delicata squash?
Usually, no. That is the whole charm. Most delicata skins are thin and become tender when roasted. Just scrub it well and slice. If your squash is very large, older, or the skin looks extra tough, you can peel it, but I rarely find it necessary.
Can I use butternut or acorn squash instead?
Absolutely. Peel butternut, and for acorn squash you can leave the skin on but it stays a bit firmer. Cut into similar-size pieces so everything roasts evenly.
Why is my squash not getting browned?
Usually it is one of three things: the pan is crowded, the oven is not hot enough, or the squash is too wet. Give it space, roast at 425°F, and pat the cut sides dry if your squash seems extra moist.
How do I keep the brown butter from burning?
Use medium heat and stay close. Butter can go from perfect to scorched fast, especially in a hot pan. Once you see golden bits at the bottom and smell a nutty aroma, pull it off the heat right away because it keeps cooking in the hot pan.
Can I make any of this ahead?
You can roast the squash ahead and re-crisp it on a sheet pan at 400°F for a few minutes. The brown butter drizzle can be made ahead too and gently rewarmed until just melted, but the sage will lose some of its crisp if it sits.
What can I add to make it more of a meal?
Toss the finished squash with arugula and cooked farro, add goat cheese, toasted pepitas, and a quick lemon squeeze. Or pile it on toast with ricotta and chili flakes.
