Ingredients for Roasted Acorn Squash

• 2 medium acorn squash (about 1-1.5 pounds each)
• 2 tablespoons olive oil (or avocado oil)
• Sea salt and black pepper, to taste
• 2 tablespoons maple syrup (optional, for serving)
• 1 tablespoon butter (optional, for serving)

How to Select the Best Acorn Squash

Look For:

• Heavy for its size: Indicates dense, moist flesh
• Firm, hard skin: Should have no soft spots or blemishes
• Dark green color: With orange patches (this is normal as they ripen)
• Dull, matte finish: Shiny skin indicates the squash was picked too early
• Intact stem: Shows freshness

Peak Season: Acorn squash is best from September through December.

How to Cut Acorn Squash for Roasting

Method 1: Halves (Recommended for This Recipe)

1. Find the ridges: Locate a ridge that runs lengthwise from stem to tip
2. Score first (optional): Run your knife along the ridge to create a guide—this makes cutting easier
3. Cut in half: Slice lengthwise from stem to tip, following the natural ridge
4. Remove seeds: Use a spoon to scoop out all seeds and stringy fibers (save seeds for roasting if desired)

Pro Tip: A sharp chef’s knife is essential. If your squash is very tough, microwave it for 2-3 minutes to soften slightly before cutting.

Method 2: Slices (Alternative)

1. Cut squash in half lengthwise and remove seeds
2. Place cut-side down on cutting board
3. Slice crosswise into 1-inch thick half-moons
4. Roasting time will be slightly shorter (20-25 minutes)

How to Roast Acorn Squash

Step 1: Prep and Season

Preheat oven to 425°F (218°C). Line a baking sheet with foil, parchment paper, or leave bare if it’s nonstick (bare gives best caramelization). Place squash halves cut-side up. Drizzle the flesh generously with olive oil—don’t skimp! Season with sea salt and black pepper.

Step 2: Roast Cut-Side Down

Flip squash halves cut-side down on the baking sheet. This creates caramelization and prevents drying out. Roast for 20-30 minutes until almost tender when pierced with a fork, with slight resistance remaining.

Step 3: Add Maple Syrup (Optional)

Remove squash from oven and flip cut-side up. Drizzle with maple syrup. Return to oven and continue roasting for 5-10 more minutes until completely tender and caramelized.

Step 4: Serve with Butter

Remove from oven and place ½ tablespoon butter inside each squash half. The butter will melt into the warm flesh, creating rich, buttery goodness.

Tips for Perfectly Roasted Acorn Squash

Use a Bare Pan for Maximum Browning: A bare nonstick baking sheet creates the best caramelization. Foil is a close second. Parchment paper prevents sticking but reduces browning.

Don’t Skimp on Oil: The generous amount of olive oil is crucial for caramelization. Using less results in less browning and flavor.

Roast Cut-Side Down First: This creates more caramelization and prevents the flesh from drying out. Flip only near the end for the maple syrup.

Check for Doneness: The squash is done when a fork or knife slides in easily with no resistance. Roasting time varies by squash size.

Broil for Extra Browning: If you want darker caramelization, broil for 2-3 minutes at the end. Watch closely to prevent burning.

Season Generously: Don’t be shy with salt—it brings out the natural sweetness of the squash.

Let It Rest: Allow the roasted squash to cool for 2-3 minutes before serving so the butter can melt and meld with the flesh.

Flavor Variations

Fall Spiced: Add ½ teaspoon cinnamon and ¼ teaspoon nutmeg (or use pumpkin pie spice) for warm, cozy fall flavors.

Herbs: Sprinkle with dried rosemary, thyme, sage, or Italian seasoning before roasting for savory depth.

Garlic Parmesan: Season with ½ teaspoon garlic powder along with salt and pepper. Top with grated Parmesan cheese in the last 5 minutes of baking.

Chili Lime: Add ½ teaspoon chili powder and squeeze fresh lime juice over the finished squash for a zesty kick.

Brown Sugar Instead: Replace maple syrup with 1 tablespoon brown sugar per half for a deeper, molasses-like sweetness.

Stuffed Acorn Squash: Use this roasting method as a base, then stuff with quinoa, wild rice, sausage, or other fillings for a complete meal.

Honey Glazed: Use honey instead of maple syrup for a different sweetness profile.

Storage and Reheating

Refrigerator: Store leftover roasted acorn squash in an airtight container for up to 4-5 days.

Reheating:

• Microwave: Heat for 1-2 minutes until warmed through (easiest method)
• Oven: Reheat at 350°F for 10-15 minutes for better texture and flavor

Freezing:

• Raw squash: Peel, seed, and slice before freezing in airtight containers for up to 12 months
• Roasted squash: Cool completely and freeze in airtight containers or freezer bags for 6-8 months

Leftover Ideas:

• Make acorn squash soup
• Add to fall salads
• Mash and use as a side dish
• Blend into smoothies
• Use in pasta dishes or grain bowls

Can You Eat Acorn Squash Skin?

Yes! The skin of acorn squash is completely edible and becomes tender when roasted. However, some people prefer not to eat it if they find it too tough. The skin also contains fiber and nutrients, making it a healthy choice to include.

What Does Acorn Squash Taste Like?

Roasted acorn squash has a mildly sweet, nutty flavor similar to butternut squash or sweet potatoes. The flesh is tender, moist, and slightly firm—not as creamy as butternut squash but still deliciously smooth. When roasted with maple syrup, the natural sweetness intensifies, creating a perfect balance of sweet and savory.
