Pistachio Nuts: The Complete Guide (Types, Nutrition & Uses)

Pistachios are one of the world's oldest and most-loved snacking nuts — sweet, buttery, satisfyingly crunchy, and packed with protein and fibre. Whether you're buying them for everyday snacking, cooking, or gifting, this guide covers everything worth knowing: where pistachios come from, the different types, how nutritious they are, how to store them, and the best ways to enjoy them.

Where Do Pistachios Come From?

Pistachios grow on small, hardy trees (Pistacia vera) that thrive in hot, dry climates with cool winters. They're native to the Middle East and Central Asia and have been eaten for thousands of years. Today the biggest producers are Iran, the United States (California) and Turkey — Turkish Antep pistachios in particular are prized for their deep flavour and vivid green colour.

Each pistachio grows inside a hard shell that naturally splits open as the nut ripens — that little smile is a sign the nut is mature and ready to eat.

The Different Types of Pistachios

• In-shell pistachios — the classic snacking format. You crack the shell yourself, which naturally slows you down (handy for portion control).
• Pistachio kernels (shelled) — the nut removed from the shell, ready to use. Ideal for baking, cooking, salads and desserts. Try our raw pistachio kernels.
• Roasted & salted pistachios — roasted for a deeper, nuttier flavour with a touch of salt; the most popular snacking choice. Shop roasted & salted pistachios.
• Unsalted / raw pistachios — untreated, lower in sodium, perfect for cooking. More in our guide to roasted vs raw pistachios.
• Flavoured pistachios — chilli & lime, lemon, saffron and more, for something different.

You'll find every one of these in our pistachio collection.

Can You Eat Pistachio Shells?

No — pistachio shells aren't meant to be eaten. They're hard, fibrous and difficult to digest, and can be a choking hazard. Stick to the kernel inside. That said, don't just bin the shells: they're great composted, or used in the bottom of plant pots for drainage.

How to Store Pistachios So They Stay Fresh

Pistachios keep best in an airtight container in a cool, dry, dark place, away from strong-smelling foods (nuts absorb odours). For longer storage, keep them in the fridge or freezer — this slows the natural oils from turning and keeps them fresh for months. Our packs are resealable specifically to help with this.

The Best Ways to Enjoy Pistachios

• Straight from the pack as a high-protein snack
• Chopped over salads, roasted vegetables or yoghurt
• Blitzed into homemade pistachio paste for desserts and ice cream
• Baked into cakes, cookies and energy bars
• On a grazing or cheese board
