How to Roast Walnuts With Brown Sugar the Right Way

Roasting walnuts with brown sugar is simple when you follow a few key steps.
 
Here’s the process broken down so you get that candied, crunchy result.
 

1. Gather Your Ingredients

To roast walnuts with brown sugar, you’ll need two cups of raw walnut halves, three tablespoons of brown sugar, one tablespoon of melted butter, and a pinch of salt.
 
You can also add a half teaspoon of cinnamon or vanilla extract if you want extra flavor.
 
Make sure your walnuts are raw and unsalted, since roasted or salted ones won’t absorb the brown sugar coating the same way.
 

2. Preheat and Prepare

Preheat your oven to 300°F (150°C).
 
Line a baking sheet with parchment paper or a silicone mat so the brown sugar coating doesn’t stick.
 
While the oven heats, melt your butter in a small bowl.
 

3. Coat the Walnuts

In a mixing bowl, combine the brown sugar, melted butter, salt, and any spices you’re using.
 
Add the raw walnuts and stir until every piece is evenly coated.
 
This is the step that makes roasted walnuts with brown sugar so good, so take a minute to really toss them well.
 

4. Spread and Bake

Spread the coated walnuts in a single layer on your prepared baking sheet.
 
Bake for 15 to 20 minutes, stirring halfway through.
 
When you roast walnuts with brown sugar at a low temperature, the sugar caramelizes slowly instead of burning.
 
You’ll know they’re done when they smell nutty and the coating looks bubbly and glossy.
 

5. Cool and Store

Let the walnuts cool completely on the baking sheet.
 
They’ll feel soft at first, but as they cool, the brown sugar coating hardens into a crisp shell.
 
Once cooled, store your roasted walnuts with brown sugar in an airtight container at room temperature for up to two weeks.
 

Tips for Perfect Roasted Walnuts With Brown Sugar

Getting roasted walnuts with brown sugar just right comes down to a few small details.
 
Keep these tips in mind so your batch turns out perfectly every time.
 

1. Don’t Walk Away From the Oven

Brown sugar can go from caramelized to burnt in just a couple of minutes.
 
Stay nearby and check your walnuts often, especially during the last five minutes of roasting.
 

2. Stir Halfway Through

Stirring the walnuts halfway through baking helps the brown sugar coating spread evenly.
 
It also prevents the nuts on the edges from burning while the ones in the center stay pale.
 

3. Use Parchment Paper

Parchment paper is your best friend when you roast walnuts with brown sugar.
 
It keeps the sticky coating from gluing the nuts to the pan and makes cleanup a breeze.
 

4. Adjust Sweetness to Taste

If you like a lighter coating, use two tablespoons of brown sugar instead of three.
 
For a thicker candied shell, add an extra tablespoon and toss the walnuts a bit longer before baking.
 

5. Add a Pinch of Sea Salt

A little flaky sea salt sprinkled on right after baking balances the sweetness beautifully.
 
It’s a small touch that makes roasted walnuts with brown sugar taste even more irresistible.

The heat balances the brown sugar beautifully and keeps you reaching for more.

This variation of roasted walnuts with brown sugar has a deeper, richer taste that’s fantastic on salads or oatmeal.
