How To Salt Walnuts

You can salt walnuts at home by tossing them with a little oil, seasoning them, and baking them until they’re crisp and golden.
 
It’s a simple process, and once you learn how to salt walnuts, you’ll wonder why you ever bought the store-bought kind.
 
The best part is that salted walnuts are incredibly versatile.
 
You can enjoy them as a snack, sprinkle them over salads, or add them to cheese boards.
 
In this post, we’ll walk through exactly how to salt walnuts, the best methods for doing it, and a few tips to make sure they turn out perfectly every single time.
 
Let’s get right into it.
 

How to Salt Walnuts: The Simple Answer

Salting walnuts is easy, and it comes down to three basic steps: coat, season, and roast.
 
First, you need to decide whether you’re working with raw walnuts or already-roasted ones.
 
If you’re starting with raw walnuts, you’ll need to roast them yourself to get that crunchy texture.
 
If you already have roasted walnuts, you can skip straight to the seasoning step.
 
Either way, the goal is the same: get the salt to stick to the nuts and enhance their natural flavor.
 
Here’s a quick overview of how to salt walnuts properly.
 

1. Start With Raw or Roasted Walnuts

You can salt walnuts whether they’re raw or already roasted, but the process looks a little different for each.
 
Raw walnuts need to be roasted first, which helps bring out their natural oils and gives them that satisfying crunch.
 
Roasted walnuts just need a light coating of oil and salt before they’re ready to eat.
 

2. Add a Little Oil So the Salt Sticks

Salt won’t stick to dry walnuts, so you need a little bit of oil to help it adhere.
 
You can use olive oil, avocado oil, melted butter, or even a light spray of cooking oil.
 
Just a teaspoon or two is enough for a couple of cups of walnuts.
 
Toss the walnuts in the oil until they’re evenly coated.
 

3. Season With Salt (and Anything Else You Like)

Now it’s time to add the salt.
 
For a basic batch of salted walnuts, use about half a teaspoon of fine sea salt or kosher salt per cup of walnuts.
 
You can always add more later, so start light and taste as you go.
 
This is also the moment to get creative if you want.
 
You can add smoked paprika, garlic powder, cinnamon, or even a pinch of cayenne for a little heat.
 

Best Methods for How to Salt Walnuts

There are a few different ways to salt walnuts, and each one has its own advantages depending on how much time you have and what equipment you’re working with.
 

1. Oven-Roasting Walnuts

Oven-roasting is the classic method and probably the most popular way to salt walnuts.
 
Preheat your oven to 350°F (175°C).
 
Spread the oil-coated walnuts in a single layer on a baking sheet lined with parchment paper.
 
Roast them for about 8 to 10 minutes, stirring halfway through so they cook evenly.
 
When they’re done, take them out and immediately sprinkle salt over the hot walnuts.
 
The residual heat helps the salt stick.
 
Let them cool completely before storing.
 

2. Stovetop Toasting in a Skillet

If you don’t want to fire up the oven, you can salt walnuts on the stovetop.
 
Heat a dry skillet over medium heat and add the walnuts.
 
Toast them for about 4 to 6 minutes, stirring frequently so they don’t burn.
 
Once they’re fragrant and starting to darken, remove them from the heat.
 
Toss them with a little oil and salt right away.
 

3. Air Fryer Method for Quick Salted Walnuts

An air fryer works great if you want salted walnuts in a hurry.
 
Set the air fryer to 320°F (160°C) and spread the walnuts in a single layer in the basket.
 
Cook for about 5 to 7 minutes, shaking the basket halfway through.
 
Once they’re done, toss them with oil and salt while they’re still hot.
 

4. No-Bake Method With Pre-Roasted Walnuts

If you already have roasted walnuts on hand, you can salt walnuts without any cooking at all.
 
Just toss them with a small amount of oil and sprinkle salt over them.
 
Spread them out on a baking sheet and let them sit for about 15 minutes so the oil and salt set.
 
This method is quick, and it’s perfect when you need salted walnuts for a recipe right away.
 

Tips for Perfectly Salted Walnuts Every Time

Getting salted walnuts right is mostly about technique, and a few small tweaks can make a big difference.
 

1. Don’t Skip the Cooling Step

Walnuts continue to crisp up as they cool, so don’t judge their texture straight out of the oven.
 
Give them 10 to 15 minutes to cool on the baking sheet, and they’ll be crunchier than you expect.
 

2. Watch Them Closely to Avoid Burning

Walnuts can go from perfectly toasted to burnt in under a minute.
 
Stay close to the oven or skillet, and set a timer so you don’t forget about them.
 

3. Store Salted Walnuts Properly

Once your salted walnuts have cooled, store them in an airtight container at room temperature.
 
They’ll stay fresh for about two to three weeks, though they rarely last that long.
 
For longer storage, keep them in the fridge for up to three months or freeze them for up to a year.
 

So, How to Salt Walnuts?

You can salt walnuts by coating them in a little oil, sprinkling them with salt, and roasting them until they’re golden and crisp.
 
Whether you use the oven, a skillet, or an air fryer, the process is quick and the results are delicious.
 
Now that you know how to salt walnuts, you can make your own batch anytime a craving hits.
 
So grab some walnuts, heat up your oven, and enjoy the perfect salty, crunchy snack.
