What Can You Do With Hazelnuts? Unlocking the Nutty Potential
Hazelnuts are incredibly versatile: they can be enjoyed raw as a healthy snack, roasted to enhance their flavor, ground into flour for gluten-free baking, or transformed into delicious spreads, oils, and even beverages.
A Deep Dive into the Hazelnut World
Hazelnuts, also known as filberts, are the edible kernels of the hazel tree (Corylus species), primarily Corylus avellana. These nutrient-rich nuts have been enjoyed for centuries, finding their way into countless culinary creations and even medicinal applications. But what truly unlocks the magic of the hazelnut? It’s understanding its versatility and knowing how to harness its unique properties.
Nutritional Powerhouse
Beyond their delicious taste, hazelnuts are packed with nutrients:
- Healthy Fats: Rich in monounsaturated and polyunsaturated fats, beneficial for heart health.
- Vitamins & Minerals: A good source of vitamin E, manganese, copper, and B vitamins.
- Fiber: Promotes healthy digestion and helps regulate blood sugar levels.
- Antioxidants: Contains phenolic compounds that protect against cell damage.
This nutritional profile makes hazelnuts a valuable addition to a balanced diet.
From Orchard to Table: Processing Hazelnuts
The journey from hazelnut tree to edible treat involves several key steps:
- Harvesting: Hazelnuts are typically harvested in the fall when they drop from the trees.
- Cleaning: Removing debris like leaves and twigs.
- Drying: Reducing moisture content to prevent spoilage.
- Shelling: Cracking the outer shell to reveal the kernel.
- Roasting (Optional): Enhances flavor and makes the skin easier to remove.
- Further Processing: Depending on the desired end product (e.g., grinding into flour, pressing for oil).
Culinary Applications Galore
Hazelnuts shine in both sweet and savory dishes. Here’s a glimpse:
- Snacking: Enjoy them raw or roasted as a healthy and satisfying snack.
- Baking: Use hazelnut flour in cakes, cookies, and bread for a nutty flavor and gluten-free alternative.
- Spreads: Transform them into delicious hazelnut butter or chocolate-hazelnut spreads like Nutella.
- Salads & Sides: Add chopped hazelnuts to salads, grain bowls, or vegetable dishes for crunch and flavor.
- Sauces & Pesto: Incorporate them into pesto or creamy sauces for pasta or meat.
- Oils: Hazelnut oil has a delicate flavor, perfect for salad dressings or drizzling over finished dishes.
- Beverages: Hazelnut milk and syrups add a nutty flavor to coffee, tea, and other drinks.
Potential Pitfalls & How to Avoid Them
While generally safe, there are a few things to keep in mind:
- Allergies: Hazelnut allergy is a relatively common food allergy. Be mindful of cross-contamination.
- Rancidity: Due to their high fat content, hazelnuts can go rancid. Store them properly in an airtight container in a cool, dark place. Roasting can also extend shelf life.
- Phytic Acid: Hazelnuts contain phytic acid, which can inhibit mineral absorption. Soaking or sprouting can reduce phytic acid content.

FAQs: Your Hazelnut Questions Answered
What’s the best way to roast hazelnuts?
Preheat your oven to 350°F (175°C). Spread the hazelnuts in a single layer on a baking sheet. Roast for 12-15 minutes, or until the skins start to crack and the nuts are fragrant. Let them cool slightly before rubbing them in a clean kitchen towel to remove the skins. The key is to watch them carefully to prevent burning.
How can I store hazelnuts to keep them fresh?
Store shelled hazelnuts in an airtight container in the refrigerator for up to 6 months or in the freezer for up to a year. Unshelled hazelnuts can be stored in a cool, dark, and dry place for several months. Proper storage is crucial for preventing rancidity.
Can I make my own hazelnut flour?
Yes! Simply grind shelled hazelnuts in a food processor until they reach a fine, flour-like consistency. Be careful not to over-process, as this can release the oils and create hazelnut butter. Hazelnut flour is a great gluten-free alternative.
What are the benefits of hazelnut oil?
Hazelnut oil is rich in vitamin E and oleic acid, both of which are beneficial for skin health. It also has a high smoke point, making it suitable for sautéing. Its delicate flavor makes it perfect for salad dressings.
Are hazelnuts a good source of protein?
While not as high in protein as some other nuts like almonds or peanuts, hazelnuts do provide a decent amount of protein. A one-ounce serving contains about 4 grams of protein. They’re a good addition to a balanced diet.
How can I tell if hazelnuts are rancid?
Rancid hazelnuts will have a bitter or soapy taste and smell. Their texture may also be oily or sticky. Discard any hazelnuts that show signs of rancidity.
Are hazelnuts suitable for vegans?
Yes! Hazelnuts are a plant-based food and are suitable for vegans. They can be used to make vegan milk, butter, and other products. They are a versatile ingredient in vegan cooking.
What are some creative ways to use hazelnut meal?
Hazelnut meal, a coarser version of hazelnut flour, can be used to make polenta, crust for fish or chicken, or added to granola for extra texture and flavor. It adds a lovely nutty crunch to various dishes.
How can I incorporate hazelnuts into my breakfast?
Add chopped hazelnuts to your oatmeal, yogurt, or granola. You can also use hazelnut milk in your coffee or smoothies. Starting your day with hazelnuts provides a boost of nutrients and energy.
What dishes pair well with hazelnuts?
Hazelnuts pair well with chocolate, coffee, berries, apples, pears, mushrooms, and game meats. Their nutty flavor complements both sweet and savory dishes.
Where are hazelnuts primarily grown?
Hazelnuts are grown in many parts of the world, including Turkey, Italy, the United States (primarily Oregon), and Spain. Turkey is the world’s largest producer of hazelnuts.
Is there a way to sprout hazelnuts to improve digestion?
Yes! To sprout them, soak hazelnuts in water for 8-12 hours. Drain and rinse them thoroughly, then place them in a sprouting jar or on a damp cloth. Rinse and drain them twice daily for 2-3 days, until small sprouts appear. Sprouting can reduce phytic acid content, potentially improving mineral absorption and digestion. Sprouting enhances their nutritional value and digestibility.
