- 1/2 teaspoon garlic powder
- 1/2 teaspoon dried thyme

How to Make Parmesan Herb Roasted Acorn Squash Recipe
Step-by-Step Instructions
Step 1: Prepare the Oven and Squash Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper for easy cleanup. Cut the acorn squash in half lengthwise, scoop out the seeds and stringy pulp, then slice into 1/2-inch thick wedges. Leave the skin on for extra nutrients and easier handling.
Step 2: Season the Squash In a large bowl, combine the olive oil, garlic powder, dried thyme, dried rosemary, salt, and black pepper. Add the acorn squash wedges and toss until evenly coated with the herb mixture. Make sure each piece is well-seasoned.
Step 3: Arrange and Roast Arrange the seasoned squash wedges in a single layer on the prepared baking sheet, ensuring they don’t overlap. Roast for 20-25 minutes, or until the squash is tender when pierced with a fork and the edges are lightly caramelized.
Step 4: Add Parmesan and Finish Remove the baking sheet from the oven and immediately sprinkle the grated Parmesan cheese over the hot squash wedges. The residual heat will melt the cheese slightly. Return to the oven for an additional 2-3 minutes to lightly golden the Parmesan.
Step 5: Garnish and Serve Remove from oven and transfer to a serving platter. Garnish with chopped fresh parsley if desired. Serve immediately while hot and crispy.
Helpful Tips
Choose acorn squash that feels heavy for its size with a hard, unblemished skin. The skin should have a deep green color with orange patches – this indicates ripeness. When cutting, use a sharp chef’s knife and cut slowly to maintain control. If the squash is particularly hard, microwave it for 2-3 minutes to soften slightly before cutting.
For the most even cooking, try to cut all wedges to a similar thickness. Don’t overcrowd the baking sheet, as this will cause the squash to steam rather than roast. If needed, use two baking sheets. For extra caramelization, increase the oven temperature to 450°F and reduce cooking time slightly, watching carefully to prevent burning.

Difficulty: Easy
This recipe works best with medium-sized acorn squash, typically weighing 1-2 pounds. The natural sugars in the squash caramelize beautifully at high heat, creating crispy edges while maintaining a tender interior. The herb blend can be adjusted to your preference – try adding sage or oregano for variation.
Notes

Fresh herbs can be substituted for dried herbs – use 1 1/2 teaspoons of fresh thyme and rosemary instead of the dried amounts. The skin of acorn squash is completely edible and becomes tender when roasted, so there’s no need to peel it. For a dairy-free version, omit the Parmesan cheese and add a sprinkle of nutritional yeast for a similar umami flavor.
If you prefer your squash extra crispy, pat the cut surfaces dry with paper towels before seasoning. For a touch of sweetness, drizzle with a small amount of maple syrup or honey during the last 5 minutes of cooking.
Frequently Asked Questions
Can I use other types of winter squash? Yes, this recipe works well with butternut squash, delicata squash, or kabocha squash. Adjust cooking times based on the thickness of your cuts and the density of the squash variety.
How do I know when the squash is done? The squash is ready when it’s easily pierced with a fork and the edges are golden brown. The texture should be tender but not mushy.
Can I make this recipe ahead of time? While best served fresh, you can prep the seasoned squash wedges up to 4 hours in advance and refrigerate until ready to roast. The cooked squash can be reheated in a 375°F oven for 5-7 minutes.

Storage Instructions
Store leftover roasted acorn squash in the refrigerator for up to 4 days in an airtight container. To reheat, place on a baking sheet and warm in a 375°F oven for 5-7 minutes until heated through and slightly crispy again. Avoid microwaving as this will make the squash soggy.
For longer storage, the cooked squash can be frozen for up to 3 months. Thaw overnight in the refrigerator before reheating. Note that the texture may be slightly softer after freezing, but the flavor will remain delicious.
