How to Roast Raw Pistachios in the Shell?

November 12, 2025

Pistachios are healthy snacks that can be eaten raw or roasted. Roasting raw pistachios in the shell improves their taste, crunchiness, as well as increases the shelf life of pistachios, particularly with high-quality persian pistachios. In this article, we will investigate how to roast raw pistachios in the shell.

Step-by-Step Roasting Process

How do you roast raw pistachios in the shell? Here are the steps:

Oven Roasting

Preheat the oven to 350°F (177 °C) when using shelled pistachios or 375°F (190 °C) when using pistachios in the shell.
Place pistachios on a lined baking sheet in a single layer, but they must have some spacing to roast evenly.
Place in the oven and bake 7-10 minutes, halfway checking and mixing. Pistachios are cooked when they become slightly brown and emit a nutty smell.
Additional flavor: Sea salt, lemon juice or other preferred spices can be sprinkled over the nuts, then roasted (as in Persian-style roasting).
Take off the pistachios and allow them to cool down to maintain their crunchiness.
Keep in a tight container for no more than two weeks to keep fresh.

Stovetop Roasting

Heat a dry skillet and turn the heat to medium.
Spread the pistachios in one layer and stir it or toss it regularly to avoid burning for 5-7 minutes in the oven until they are aromatic and golden.
Take onto a plate and allow to cool; garnish with salt or seasoning to taste.

Roasting Raw Shelled vs. In-Shell Pistachios

To understand how to roast raw shelled pistachios, let’s compare the methods:

Method	Temperature	Time	Notes
Oven (shelled)	350°F (177°C)	7–10 min	Most even, customizable
Oven (in-shell)	375°F (190°C)	8–12 min	Persian style: add salt, lemon
Stovetop	Medium	5–7 min	Requires frequent stirring

Roasting raw pistachios in the shell is simple: just spread them in a single layer on a baking sheet, bake in a preheated oven at 375°F (190°C) for 8–12 minutes, stirring halfway, and cool before storing in an airtight container for up to two weeks; alternatively, use a dry skillet on medium heat, stirring for 5–7 minutes until golden and aromatic.

Buying and Preparation Tips of Pistachios

Here are some tips on how to buy and how to roast raw pistachios in the shell:

Find good sources of bulk or Iranian pistachios; make sure they are fresh and of high quality.
