How to Make Spicy Caramelized Butternut Squash with Lemon and Hazelnuts Recipe
Step 1: Preheat Your Oven
Start by setting your oven to 425°F (220°C). This high temperature is key to achieving that perfect tender inside with caramelized edges that bring out the natural sugars in the squash.
Step 2: Prepare the Butternut Squash
Peel your butternut squash, remove any seeds, and chop it into roughly 1-inch cubes. Uniform pieces will roast evenly, ensuring each bite has that perfect balance of soft interior and caramelized crust.
Step 3: Toss Squash with Flavorful Coating
In a large bowl, combine your squash cubes with olive oil, maple syrup, ground cinnamon, cayenne pepper, salt, and black pepper. Toss everything well so each piece is evenly coated—this is what gives the dish its incredible sweet, spicy, and savory profile.
Step 4: Arrange on the Baking Sheet
Line a baking sheet with parchment paper to prevent sticking, then spread the squash out in a single layer. Avoid overcrowding, which helps each cube roast properly instead of steaming.
Step 5: Roast Until Caramelized
Place the baking sheet in the oven and roast the squash for about 25 to 30 minutes. Be sure to turn the cubes halfway through roasting to ensure even caramelization and tenderness throughout.
Step 6: Add Lemon Zest and Juice
Once the squash is roasted, remove it from the oven and immediately sprinkle the lemon zest and juice over it. Gently stir to combine—the citrus juice brightens the dish and balances the sweetness perfectly.
Step 7: Toast the Hazelnuts
While the squash finishes roasting, heat a dry skillet over medium heat and toast the hazelnuts. Stir frequently for about 5 to 7 minutes until they become golden and fragrant. Toasting the nuts enhances their flavor and adds a delightful crunch to the dish.
Step 8: Combine Hazelnuts with Squash
Add the toasted hazelnuts to the lemony squash and gently toss to incorporate. The contrast of textures here takes this recipe over the top in every bite.
Step 9: Garnish and Serve
Transfer everything to a serving dish and sprinkle with fresh parsley if you like. This adds a fresh, herbal note and a burst of green that makes the dish look as good as it tastes.
