Simply cut the squash, toss it on a sheet pan, and roast until tender. Finish with a sprinkle of Parmesan for a rich, flavorful mash that’s perfect for any meal.

This squash season, my kitchen was overflowing with beautiful, orange butternut squash from the local farmers’ market.

The aroma of caramelized squash roasting on a sheet pan filled the house, and every bite felt like a cozy celebration of fall’s harvest.
Serve Roasted Squash Side Dish Recipe for Parties
This makes a perfect side dish for parties because it’s easy to prepare and looks beautiful on a platter. Arrange the squash on a serving dish and sprinkle with a little extra parmesan if you like. The caramelized edges and soft centers make this side dish a crowd-pleaser.
Choose the Best Quality Butternut Squash
When selecting butternut squash, choose firm squash with smooth skin and no soft spots. A smaller squash often has sweeter, more flavorful flesh perfect for roasting. Cutting in half ensures even cooking when you roast them on a sheet pan lined with parchment paper.

Parmesan Cheese with Squash
Adding parmesan cheese improves this recipe with a nutty, salty flavor. Sprinkle the cheese over the squash during the last few minutes of roasting in the oven at 400 degrees. The result is a caramelized, cheesy squash that pairs perfectly with shrimp, pork tenderloin, popcorn chicken, or chicken curry.

STEP-BY-STEP INSTRUCTIONS TO COOK BUTTERNUT SQUASH
First Step: Preheat and Prep
Preheat your oven to 425°Fahrenheit (220°Celsius) to get it ready for roasting. Slice the butternut squash in half, remove the seeds, and arrange the halves cut-side up on a baking tray. Brush the flesh with olive oil and season generously with salt and pepper, then flip them over and poke the skin a few times with a fork.
Second Step: Roast Squash
Place the squash in the oven and roast for 60–75 minutes until the flesh is tender and caramelized. Check occasionally to ensure it doesn’t burn and is cooking evenly. This roasting process brings out a deep, sweet flavor in the squash.
Third Step: Scoop Out Flesh
Switch the oven to broil while you scoop the soft flesh into a bowl, leaving a small border of squash in the skins. Be careful not to pierce the skin, so it holds the mash later. This makes it easy to refill and present the squash once the filling is ready.
Fourth Step: Mash the Filling
Add the Parmesan, Greek yogurt, garlic powder, salt, and pepper to the scooped squash. Mash everything together until it reaches a smooth, creamy texture. This velvety filling will be rich, flavorful, and perfect for the squash shells.
Fifth Step: Broil and Add Toppings
Spoon the mashed filling back into the empty squash shells and place them under the broiler for 1–2 minutes to lightly brown the tops. Remove from the oven and sprinkle with toasted nuts and sliced scallions for crunch and freshness. Serve warm and enjoy the nutty, cheesy flavor of the squash.

TIPS AND TRICKS:
- Use Parchment Paper: Line your sheet pan with parchment paper before roasting. It makes cleanup easier and prevents the squash from sticking while caramelizing in the oven to 400 degrees.
- Season Well: Toss the squash with olive oil, salt, and pepper before roasting. Proper seasoning improves the natural sweetness of the squash and gives the mash a richer flavor.
- Add Parmesan at the End: Sprinkle grated Parmesan over the squash during the last 5 minutes of roasting. This allows the cheese to melt and lightly caramelize without burning, adding a nutty, cheesy layer to the side dish.
