What Are Peanuts, unsalted and How Can I Use Them?

Here's everything worth knowing about peanuts, unsalted and how to pick them, what they is, how to store them, and what to use instead, plus 20 recipes to cook tonight.

Key Points

Peanuts with no salt added: the default when you want to control the seasoning yourself.
Best for baking, candy, peanut butter, and sauces, where the recipe supplies its own salt.
Toast at 350°F (175°C) for 10 to 15 minutes to wake up flat, beany raw nuts.
High in oil, so store airtight and cool; refrigerate up to six months or freeze up to a year.

What is peanuts, unsalted?

Unsalted peanuts are peanuts with no salt added, whether raw or dry-roasted. They are the cook's default, the version you reach for whenever you want to control the seasoning yourself rather than have it decided at the factory.

That control is the whole point. In baking and in sauces, salt is part of the recipe itself, so starting from a plain peanut lets you season to taste instead of fighting a salt level you did not choose.

Raw unsalted peanuts still need cooking to taste good. Dry-roasted unsalted peanuts are toasted and ready to eat or chop straight in.

When to Reach for Unsalted

Use unsalted peanuts any time the recipe adds its own salt or sugar. Peanut brittle, candies like Cherry Mash, and baked goods such as Peanut Butter Chocolate Cookies all balance their own seasoning, so a salted peanut would throw them off. The same goes for Peanut Muffins.

They are also the right base for homemade peanut butter and for sauces, where you want to dial in the salt and heat by hand. An Indonesian Hot Peanut Sauce or the peanuts folded into a Princess Chicken- Szechuan land cleaner when the nut itself is neutral.

Toasting is the move that wakes them up. Spread raw or dry-roasted peanuts on a sheet and roast at 350°F (175°C) for 10 to 15 minutes, shaking once, until fragrant and golden.

That toasting deepens the flavor and crisps the texture before you chop them over noodles or a stir-fry.

For snacking, season them yourself. Toss warm toasted peanuts with oil and your own spice mix, the approach behind Five-spice Peanuts (Chinese New Year), or fold them into a sweet-salty brittle. You decide exactly how salty.

Pairing and a Common Mistake

Peanuts bridge sweet and savory better than almost any nut. On the sweet side they go with chocolate and caramel; on the savory side they take to soy, lime, chili, garlic, and ginger across Thai and Szechuan cooking.

The most common mistake is treating unsalted as a finished snack and being let down. Plain raw peanuts taste flat and a little beany; they are an ingredient, not a bowl-of-nuts food, until you toast and season them.

The fix takes minutes. Toast them, then salt or spice while still warm so the seasoning sticks. If a recipe already calls for added salt, leave the peanuts plain and trust the recipe.

Substitutes

Salted peanuts are the obvious swap, but cut or omit the salt elsewhere in the recipe to compensate, or the dish turns out too salty.

For a similar crunch and a sweeter, less earthy flavor, cashews or almonds work in stir-fries and baking, though they cost more and shift the taste. In peanut sauces and satays, smooth unsalted peanut butter stands in for ground peanuts and gives a creamier body.

For anyone with a peanut allergy, toasted sunflower seeds or pepitas bring a comparable crunch in salads and baking, with sunflower seed butter replacing peanut butter in sauces.

Buying and Storing

You will find unsalted peanuts both raw and dry-roasted, shelled or still in the shell. Raw ones look pale and need toasting; dry-roasted are browner and ready to use. For most cooking and baking, shelled dry-roasted unsalted peanuts are the convenient pick.

Peanuts are high in oil, so they go rancid faster than they look like they should. Keep them in an airtight container away from light and heat, where they hold a few months in the pantry.

For longer storage, refrigerate them for up to six months or freeze for up to a year; the cold keeps the oils from turning. A stale, paint-like or bitter smell means they have gone rancid, so toss any that smell off rather than baking them into something.

Buy raw if you want maximum control and plan to toast them anyway, since freshly toasted peanuts beat any pre-roasted bag for flavor.
