Ingredients
- 2 Small to Medium Acorn Squash
- ¼ cup Extra-Virgin Olive Oil
- 1 cup Finely Grated Parmesan Cheese (freshly grated is best)
- 1 tsp Garlic Powder
- ½ tsp Kosher Salt
- ½ tsp Dried Basil
- ½ tsp Dried Thyme
- ½ tsp Dried Oregano
- Optional: Black Pepper, for seasoning
Instructions (Step-by-Step)
- Prep Squash: Preheat the oven to 425°F (220°C). Slice the top and bottom off both acorn squash. Place each squash on a flat end and slice it in half vertically. Scoop out the seeds and stringy flesh with a spoon. Slice each half into 1-inch thick slices. Note: Do not peel the skin.
- Seasoning Toss: Add the squash slices to a large mixing bowl. Add the oil, Parmesan cheese, garlic powder, salt, basil, thyme, and oregano. Use your hands to toss the ingredients thoroughly until every slice is coated in the oil and the herb mixture.
- Roast: Place the roasted acorn squash slices on a parchment-lined baking tray, ensuring the pieces are not overlapping. If there is extra cheese mixture left in the bowl, press it onto the top side of the slices for an extra crispy crust.
- Bake and Serve: Bake for 20 to 25 minutes, or until the squash is perfectly tender when pierced with a fork and the Parmesan herb crust is lightly golden brown. Transfer to a serving platter and enjoy immediately.
Storage and Reheating
Store cooled leftovers in an airtight container in the refrigerator for up to 5 days.
Freezing: Cooled slices can be frozen for up to 3 months. Thaw overnight and reheat in the oven or air fryer.
Reheating Tip: Reheat slices on a baking sheet in a 350°F (175°C) oven or in an air fryer for 5–8 minutes. This is the best way to restore the crispiness of the Parmesan herb coating.
Expert Tips
- Skin is Edible: The skin of the acorn squash softens significantly during roasting and is perfectly safe (and delicious) to eat. Leaving the skin on helps the slices maintain their shape and saves prep time!
- Fresh Grate the Parmesan: Always use freshly grated Parmesan off the block. Pre-shredded cheese contains anti-caking agents that can leave the crust mealy and prevent it from melting and crisping properly.
- The Savory Spice Blend: Stick to dried herbs for this recipe. Fresh herbs can burn easily at the high roasting temperature (425°F). Dried basil, thyme, and oregano are robust enough to stand up to the heat.
- Crispy Crust Maximization: Ensure the squash slices are not touching or overlapping on the baking sheet. Give them room to breathe so they can roast and crisp up instead of steaming.
Variations
- Cheese Swap: Use shredded Gruyere, Asiago, or Pecorino Romano cheese instead of Parmesan for a sharper, nuttier flavor.
- Spicy Kick: Add a pinch of red pepper flakes or smoked paprika to the herb mixture for a touch of heat and color.
- Balsamic Glaze: After the squash is fully roasted, drizzle the slices with a balsamic glaze for a contrasting sweet and sour note.
- Other Squash: This savory acorn squash recipe works beautifully with other thin-skinned squash, such as Delicata squash (which is also easy to slice and does not need peeling).
Serving Suggestions
Pair this vibrant thanksgiving side dish with hearty holiday entrées:
- Protein: Roast Chicken, Holiday Ham, or Prime Rib.
- Other Sides: Creamy Mashed Potatoes, Roasted Root Vegetables, or a simple green salad.
- Garnish: A final sprinkle of coarse sea salt or chopped fresh parsley.
Frequently Asked Questions
Q: Do I really need to use finely grated Parmesan? A: Yes. The fine, powdery consistency of finely grated Parmesan is crucial because it allows the cheese to melt and combine with the oil to form a thin, golden, crispy crust. Coarsely shredded cheese tends to burn before the squash is tender.
Q: Can I peel the acorn squash skin off? A: You can, but it is not recommended for this roasted acorn squash slices recipe. Peeling is difficult, and the skin helps the slices maintain their shape during the high-heat roasting. The skin is completely soft and edible after cooking.
Q: Can I use this seasoning blend on other vegetables? A: Absolutely! This Parmesan herb mixture is fantastic on Brussels sprouts, cauliflower, sweet potatoes, or broccoli florets. Follow the same high roasting temperature (425°F) for 20–25 minutes.
Q: What is the best way to cut the hard acorn squash safely? A: To cut the acorn squash safely, first use a sharp knife to carefully slice off the stem and blossom ends to create a stable, flat surface. Stand the squash up on the flat end, and carefully slice down the center. Use a sturdy metal spoon to scoop out the seeds.
