How to Make Spicy Caramelized Squash with Lemon and Hazelnuts Recipe
Step 1: Prepare Your Oven and Squash
Preheat your oven to 425°F (220°C) to ensure a hot environment for caramelization. While it heats, peel the squash and cut it into 1-inch cubes – uniform sizes will roast evenly and develop that coveted golden crust.
Step 2: Toss with the Flavorful Marinade
Place the squash cubes in a large bowl and drizzle with olive oil and maple syrup. Sprinkle cinnamon, cayenne pepper, salt, and black pepper over the top. Toss everything together using your hands or a spoon, ensuring every piece is coated with this irresistible spice blend that will create all the magic once roasted.
Step 3: Arrange and Roast
Line a baking sheet with parchment paper and spread your seasoned squash cubes out in one single layer with space between pieces. Overcrowding traps steam and prevents caramelization. Roast for 25 to 30 minutes, turning the squash halfway through roasting to brown all sides evenly. You want the squash to be tender yet beautifully caramelized.
Step 4: Add Lemon Zest and Juice
Once out of the oven, immediately sprinkle the squash with freshly grated lemon zest and squeeze the juice from one lemon over the top. This bright citrusy lift cuts through the sweetness and spice, giving the dish a vibrant, fresh finish.
Step 5: Toast the Hazelnuts
While the squash is roasting, toast the hazelnuts in a dry skillet over medium heat. Stir frequently for 5 to 7 minutes, until they become golden, fragrant, and just a little crunchy. This step transforms the nuts, intensifying their natural nuttiness and adding a wonderful crunch as a textural contrast.
Step 6: Combine and Serve
Carefully fold the toasted hazelnuts into your warm, lemon-splashed squash. Transfer everything to a serving dish and, if you like, sprinkle with chopped fresh parsley for an extra dash of color and freshness. Now, dig in and enjoy the delightful layers of flavor you just created!

Side Dishes

Make Ahead and Storage
Storing Leftovers
You can store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors tend to deepen overnight, making the dish even more delicious when reheated.
Freezing
If you want to keep this Spicy Caramelized Squash with Lemon and Hazelnuts Recipe longer, freezing is an option. Spread the cooled squash cubes and toasted hazelnuts on a tray to freeze individually before transferring them to a freezer bag. Use within 2 months for best quality.
Reheating

FAQs
Can I use other types of squash for this recipe?
Definitely! While butternut squash is ideal because of its sweetness and texture, you can substitute with acorn squash, delicata, or kabocha. Just be sure to adjust cooking times if needed as different squashes vary in density.
How spicy is this dish? Can I adjust the heat?
The cayenne pepper adds a gentle kick that complements the sweetness, but it’s very easy to adjust. Start with a small pinch if you prefer milder flavors, or add more if you love heat. You can also swap cayenne for smoked paprika if you want warmth without the fire.
What if I don’t have hazelnuts? Are there good substitutes?
Absolutely! Toasted walnuts or pecans offer a similarly rich, crunchy element. Almonds work well too, but keep them chopped roughly to maintain texture balance.
Is this dish suitable for vegan diets?
Yes, the recipe is naturally vegan when you use maple syrup instead of honey and of course no dairy is involved. It’s a perfect vegan side that’s packed with flavor and nutrients.
Can I prepare this recipe ahead of time for a dinner party?
For sure! You can roast the squash and toast the nuts a day ahead, then toss everything together with lemon just before serving to preserve freshness and brightness.
