How to Make Spicy Caramelized Squash with Lemon and Hazelnuts Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 425°F (220°C). This high heat is key to getting that perfect caramelized exterior on the squash cubes. Meanwhile, peel your squash carefully, remove the seeds if needed, and chop it into uniform 1-inch cubes to ensure even roasting.
Step 2: Season the Squash
Place your squash cubes in a large bowl and drizzle with olive oil and maple syrup. Sprinkle with cinnamon, cayenne pepper, salt, and black pepper. Toss everything together until every cube is coated generously—this is what sets up the spicy caramelized flavor that makes this Spicy Caramelized Squash with Lemon and Hazelnuts Recipe so irresistible.
Step 3: Roast to Perfection
Line a baking sheet with parchment paper and spread the seasoned squash out in a single layer. Avoid overcrowding to encourage caramelization rather than steaming. Roast for 25 to 30 minutes, stirring or turning halfway through to brown all sides evenly. You’ll know it’s ready when the squash is tender and beautifully caramelized with golden edges.
Step 4: Add the Lemon Zest and Juice
Once roasted, remove the squash from the oven and immediately sprinkle the lemon zest and freshly squeezed lemon juice over it. Gently fold the squash to combine everything so the zingy brightness complements the warm spices and sweetness flawlessly.
Step 5: Toast and Combine Hazelnuts
While the squash roasts, toast the hazelnuts in a dry skillet over medium heat. Stir frequently for about 5 to 7 minutes until the nuts are golden and release their enticing aroma. Add the toasted hazelnuts to the squash and mix carefully to distribute the crunchy texture throughout.
Step 6: Final Touches and Serve
Transfer your spicy caramelized squash creation to a serving dish and, if you like, sprinkle fresh chopped parsley on top for color and a fresh herbal note. Now you are ready to impress at your next meal with this stunning and flavor-packed recipe!

Reheating
Reheat gently in a 350°F (175°C) oven for about 10–15 minutes to revive some of the caramelization and crispness. Alternatively, warming it in a skillet over medium heat with a splash of olive oil works well. Avoid microwaving if you prefer to keep texture and flavor at their best.
FAQs
Can I use other types of squash for this recipe?
Absolutely! While butternut squash is classic for this recipe, you can substitute delicata, acorn, or even kabocha squash to experience different textures and subtle flavor variations.
How spicy is the dish with ½ teaspoon of cayenne?
The spice level is gentle but noticeable, adding just the right amount of heat to contrast the sweetness. Feel free to adjust the cayenne pepper quantity to make it milder or bolder according to your taste.
Can I substitute hazelnuts with other nuts?
Yes! Pecans, walnuts, or almonds toasted similarly will deliver delicious crunch and richness if you are not a hazelnut fan or have allergies.

Definitely. Just be sure to use maple syrup instead of honey, and you have a completely vegan-friendly, hearty dish packed with flavor and nutrients.

A sharp vegetable peeler works best. Start by cutting off both ends, then peel from top to bottom, rotating the squash to remove the outer skin until you reach the bright orange flesh.
