I still remember the first time I made this on a crisp fall evening with wood smoke in the air and winter setting in. I wanted something warm and comforting with the natural sweetness of the squash and a little balsamic tang to balance it out. The moment those vegetables hit the oven, the whole kitchen smelled amazing. And honestly, I've been making it ever since.

This recipe quickly became a favorite for weeknight dinners or casual Sunday meals. Everything cooks on one pan, which makes clean-up effortless, and the balance of flavors from the rosemary, garlic, and balsamic is just right. It's the kind of dish that makes everyone wander into the kitchen wondering what's cooking.

A Cozy Fall Favorite

When the evenings start to cool off, this roasted mix is exactly what I want coming out of the oven. Butternut squash, Brussels sprouts, and potatoes may be simple Southern staples, but this whole dish comes together with almost no effort at all. Just toss everything on a sheet pan, season it up, and let the oven do the work. It feels just as welcome on a Thanksgiving table as it does on a quiet weeknight with a slice of cornbread, right at home in any Southern kitchen.

How to Make Sheet Pan Roasted Butternut Squash, Brussels Sprouts, and Potatoes

Preheat your oven to 400°F. I love using a good-quality oven that holds a steady temperature, because even roasting ensures each vegetable cooks evenly.

In a large half-sheet baking pan, combine the chopped butternut squash, halved Brussels sprouts and baby potatoes, shallots, and garlic. Drizzle with olive oil, sprinkle the chopped rosemary, add the salt and black pepper, and drizzle the balsamic vinegar. Using your hands or a silicone spoonula, toss everything gently until the vegetables are evenly coated.

Spread the vegetables into a single layer on the pan. This ensures they roast rather than steam. Bake for 25 to 30 minutes, until the squash and potatoes are tender when pierced with a fork. I like to check halfway through and give the pan a gentle shake to help them brown evenly.
