The Secret to Crispy Squash Fries

Butternut squash is softer than potatoes, so thin, even fries and high heat are key. A light coating of cornstarch helps create a crisp exterior, and spreading the fries out on two pans keeps them from steaming. The Parmesan goes on halfway to form a golden, cheesy crust.

What to Serve With It

Serve with garlic aioli, spicy mayo or as a side to roast chicken and steak.

Storage and Reheating

Microwave the whole squash for 2 minutes to make peeling and cutting easier. Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in a 375°F (190°C) oven or air fryer for 8-10 minutes to keep the edges crispy.

Is It Healthy?

Butternut squash is an excellent source of vitamins A and C, plus fiber and potassium. Roasting it into fries with a little olive oil keeps the dish light and wholesome, while the caramelized edges bring out its natural sweetness. Compared to regular fries, these have fewer calories and more nutrients, so they're a side you can feel really good about serving to the whole family, especially during the cooler months.

Perfect for Any Occasion

Butternut squash fries are perfect for fall dinners, Thanksgiving tables and cozy weekend meals. Serve them as a side, a snack, or part of a colorful veggie platter. They also make a delicious holiday appetizer with a creamy dip.

Make-Ahead and Freezing Tips

Peel and cut the squash up to 3 days ahead and keep it refrigerated. Season and roast just before serving.
