Learning how to make caramelised walnuts is easier than you think, and once you nail the technique, you’ll be making them all the time.
 
In this post, we’ll cover exactly how to make caramelised walnuts, the tools you need, common mistakes to avoid, and some tasty variations to try.
 
Let’s get started.
 

How to Make Caramelised Walnuts: The Basic Method

Knowing how to make caramelised walnuts starts with understanding the two main approaches.
 
You can make caramelised walnuts on the stovetop or in the oven, and both methods deliver that signature sweet, crunchy coating.
 
Here’s a breakdown of each technique so you can choose what works best for you.
 

1. The Stovetop Method

To make caramelised walnuts on the stovetop, you’ll need a heavy skillet, sugar, butter, and a pinch of salt.
 
Start by toasting your walnut halves in the dry skillet over medium heat for about two to three minutes until they smell nutty.
 
Remove them, then add sugar to the pan and let it melt without stirring too much.
 
Once the sugar turns amber, stir in the butter and return the walnuts to the pan.
 
Toss everything quickly so the caramelised walnuts get evenly coated before the sugar hardens.
 
Spread them on parchment paper to cool, and you’ve got perfectly caramelised walnuts in minutes.
 

2. The Oven Method

If you prefer a hands-off approach to how to make caramelised walnuts, the oven method is for you.
 
Toss walnut halves with melted butter, sugar, and a pinch of salt in a bowl.
 
Spread them in a single layer on a lined baking sheet.
 
Bake at 350°F (175°C) for about ten to twelve minutes, stirring halfway through.
 
The sugar will melt and caramelise around the walnuts right in the oven.
 
This method makes caramelised walnuts with less hands-on time, though you do need to watch them closely near the end.
 

3. The Dry Caramel Method

Some people prefer to make caramelised walnuts using the dry caramel technique.
 
This means melting sugar alone in a pan without adding water or butter at the start.
 
Once the sugar liquefies and turns golden, you toss in the walnuts and stir to coat.
 
The result is a pure, crunchy shell of caramel on each walnut.
 
This is a classic way to make caramelised walnuts when you want that clean, glossy finish.

Tips for Perfect Caramelised Walnuts Every Time

Getting caramelised walnuts right comes down to a few key details.

If humidity is high, add a little parchment paper between layers to keep your caramelised walnuts from getting sticky.
