- Butternut squash: The main ingredient, peeled and cut into 1-inch cubes for even roasting.
- Olive oil: Adds a silky sheen and helps caramelize the squash for that luscious finish.
- Maple syrup: Provides natural sweetness and helps with caramelization, but honey works just as well.
- Ground cinnamon: Brings warm spice that beautifully complements the sweetness.
- Cayenne pepper: Gives just the right kick—adjust to your taste for mild or fiery heat.
- Salt and black pepper: Essential for balancing flavors and highlighting the roasting.
- Lemon zest and juice: Inject a fresh and tangy brightness that lifts the dish.
- Hazelnuts: Toasted and chopped for a crunchy texture and nutty richness.
- Fresh parsley (optional): Adds a pop of green and fresh herbal note at the end.
How to Make Spicy Caramelized Squash with Lemon and Hazelnuts Recipe
Step 1: Preheat and Prepare
Begin by setting your oven to a high temperature at 425°F (220°C). This intense heat is key for caramelizing the edges of the squash cubes, creating those little pockets of caramelized magic that make this recipe sing.
Step 2: Cube the Squash
Peel the butternut squash carefully—this might take a little elbow grease, but it’s worth it. Remove the seeds if needed, then chop into uniform 1-inch cubes to ensure even cooking and caramelization throughout.
Step 3: Toss with Flavor
In a large mixing bowl, combine the squash cubes with olive oil, maple syrup, cinnamon, cayenne pepper, and salt and pepper. Toss everything together until the cubes are evenly coated, which guarantees every bite explodes with layered flavors.
Step 4: Arrange and Roast
Line a baking sheet with parchment paper to prevent sticking, then spread the coated squash cubes out in a single layer. Make sure not to overcrowd the pan because that would steam rather than roast the squash, and we want that golden caramelization.
Step 5: Roast to Perfection
Place the squash in the oven and roast for about 25 to 30 minutes. Halfway through, give the pan a shake or turn the cubes for an even roast. You’ll know it’s done when the squash is tender inside and beautifully caramelized on the edges.
Step 6: Brighten with Lemon
Once roasted, remove the squash from the oven and immediately toss it with the freshly grated lemon zest and juicy lemon juice. This step adds the bright, refreshing contrast that lifts the sweetness and spice to a whole new level of deliciousness.
Step 7: Toast the Hazelnuts
In a dry skillet over medium heat, toast the hazelnuts while keeping them moving so they toast evenly without burning. In about 5 to 7 minutes you’ll smell that irresistible nutty aroma and see a golden glow—perfect!
Step 8: Combine for Crunch
Add those warm, toasted hazelnuts to the roasted squash and gently stir them in. Their crunch contrasts beautifully with the soft, caramelized cubes, creating layers of texture that make every bite exciting.
Step 9: Finish and Garnish
Transfer everything to a serving dish and, if you like, sprinkle with some chopped fresh parsley. The green flecks not only add a subtle fresh flavor but also make this dish look stunning on the table.
How to Serve Spicy Caramelized Squash with Lemon and Hazelnuts Recipe

Garnishes
For a little extra flair and flavor, consider topping your Spicy Caramelized Squash with Lemon and Hazelnuts Recipe with a few more toasted hazelnuts or a drizzle of extra virgin olive oil. Fresh herbs like thyme or rosemary also add a fragrant touch that complements the warmth of the cinnamon and cayenne beautifully.
Side Dishes
This dish shines as a side alongside grilled chicken, roasted pork, or even a rich piece of salmon. It’s also fantastic beside a hearty grain bowl or creamy risotto, where its bright and spicy notes cut through richness and add new layers of taste.
Creative Ways to Present
Don’t hesitate to let your imagination play! Serve this squash over a bed of lightly dressed arugula for a fresh peppery bite, or pair it with a dollop of creamy Greek yogurt or whipped feta for a luxurious contrast. For a fun twist, stuff it into warm pita pockets with some greens for an unexpected sandwich sensation.
Make Ahead and Storage
Storing Leftovers
You can easily store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making the squash even more delicious the next day. Just make sure to let it cool completely before sealing it up.
Freezing
If you want to keep the Spicy Caramelized Squash with Lemon and Hazelnuts Recipe for longer, freezing is an option. Place cooled squash in a freezer-safe container or bag and store for up to 2 months. Though the texture might soften a bit upon thawing, the flavor remains robust and satisfying.
Reheating
To reheat, warm the squash gently in a skillet over medium heat to help the caramelized edges crisp back up, or use an oven at 350°F (175°C) for 10-15 minutes. Avoid the microwave if you want to maintain the best texture and flavor.
FAQs
Can I use a different type of squash?
Absolutely! While butternut squash is ideal for its sweetness and texture, other varieties like acorn or delicata can work well too. Just be mindful of cooking times as they might differ slightly.
How spicy is this dish?
The cayenne pepper adds a gentle heat that you can easily adjust. If you prefer mild, use less or skip it altogether. If you love a punch of spice, feel free to increase the amount or add a pinch of smoked paprika for a smoky touch.
Can I substitute the hazelnuts?
Yes! If hazelnuts aren’t your favorite or if you have allergies, toasted pecans or walnuts make great alternatives, adding their own unique crunch and depth.
Is this recipe vegan?
It certainly can be! Just be sure to use maple syrup instead of honey to keep the recipe fully plant-based.
What’s the best way to peel butternut squash?
A sharp vegetable peeler works wonders, but warming the squash slightly in the microwave for a minute can soften the skin and make peeling easier and safer.

I truly hope you give this Spicy Caramelized Squash with Lemon and Hazelnuts Recipe a try because it’s one of those dishes that feels both special and comforting at the same time.
