Ingredients for How to Roast Acorn Squash

1 medium acorn squash
1 Tablespoon olive or avocado oil
1/2 teaspoon sea salt
1/2 teaspoon pepper
1/2 teaspoon garlic granules (or garlic powder)
2 Tablespoons fresh thyme
Crushed red pepper for topping (optional)

How to Make How to Roast Acorn Squash

Preheat your oven to 400°F (200°C) and line a rimmed baking sheet with parchment paper or foil for easier cleanup.
Wash and thoroughly dry the acorn squash. This helps the oil coat evenly and ensures crisp edges.
Carefully cut the squash in half lengthwise, just off-center of the stem. Use a spoon to scrape out the seeds and stringy pulp, creating a clean cavity.
Trim any tough stems from the top and bottom of the squash, then cut each half into 1-inch thick slices.
Place the slices in a large mixing bowl. Drizzle with oil, season with salt, pepper, and garlic granules, and toss until each slice is evenly coated.
Arrange the slices on your prepared baking sheet, ensuring they don’t overlap. Overcrowding traps steam, resulting in soggy squash instead of crispy edges.
Roast for 20 minutes, then carefully flip each slice with tongs or a spatula. Continue roasting for another 20 minutes, or until the squash is soft and golden brown.
Before serving, garnish with fresh thyme, a sprinkle of flaked sea salt, and a pinch of crushed red pepper if you like. Serve warm and enjoy!

Our Team’s Tips for the Best How to Roast Acorn Squash

Leave space on the baking sheet: Give each slice enough room to roast evenly and develop those irresistible crispy edges.
Use high-quality oil: A good olive or avocado oil adds flavor and helps the squash cook perfectly.
Choose the right squash: Look for one that’s firm, heavy for its size, and free of blemishes.
Season just before roasting: If you season too early, the salt can draw out moisture, leading to soggy squash.
Make it ahead: Roasted squash stays fresh for up to 4 days in the fridge. Reheat in the oven or sauté pan to restore crispiness.
