Easy Candied Walnuts Recipe

These candied walnuts are raw walnut halves cooked in a cinnamon sugar syrup on the stovetop until the sugar dries into a crunchy, sandy shell. You need 2 cups of walnuts, 1 cup of sugar, ¼ cup of water, cinnamon, and a pinch of salt. It takes about 15 minutes and makes about 2 cups.

The one thing to watch is the moment the shiny syrup turns grainy and white. That looks wrong the first time. It is exactly the point where you stop, and it is how old fashioned sugared walnuts have always been made, no oven and no candy thermometer.

What Goes Into Cinnamon Sugar Walnuts

• 2 cups raw walnut halves: halves coat more evenly than pieces, which burn at the thin edges
• 1 cup granulated sugar and ¼ cup water: enough syrup to coat every nut once it reduces
• ½ teaspoon ground cinnamon: warm, but it does not take over
• ¼ teaspoon salt: keep it; without it the walnuts taste flat and only sweet
• ½ teaspoon vanilla extract (optional): stirred in off the heat so it does not cook away

No butter and no corn syrup. That is why the coating dries crisp instead of staying tacky, and why the nuts keep for two weeks in a jar.

Raw or Roasted Walnuts for Candying?

Use raw. I have tried both, and roasted walnuts already carry oil on the surface, sometimes salt too, so the sugar slides off instead of gripping. They also roast a second time in the pan, which is how you end up with a bitter aftertaste.

Raw halves toast while the sugar cooks, about 10 minutes in total. That is just enough to bring out the nutty flavor. Smell them first if they have been in the cupboard a while: walnuts with a paint-like smell have gone rancid, and sugar will not hide it.

Cooking the Syrup Until the Walnuts Turn Sandy

Line a baking sheet with parchment or a silicone mat first. You will need it in a hurry at the end.

Put the sugar, cinnamon, salt, and water in a medium nonstick skillet or saucepan and stir. Bring it to a boil over medium high heat, then turn the heat down slightly and stir for about 2 minutes, until the sugar has fully dissolved and the syrup looks clear.

Add the walnuts and keep stirring. Over the next 5 to 7 minutes the syrup reduces, gets sticky, and then suddenly goes cloudy. Keep the nuts moving the whole time. The edge between toasted and scorched is short, so this is not the moment to check your phone.

Glossy, Then Sticky, Then Grainy

Here is what is happening. As the water boils off, the syrup gets so full of sugar that stirring makes it turn back into tiny crystals, and those crystals set on the walnuts. The coat goes from shiny to matte and dry, like wet sand. When the nuts look dry and evenly coated, take the pan off the heat, stir in the vanilla if using, and tip everything onto the lined sheet straight away.

Spread them into a single layer and pull apart any that are stuck together with two forks. Let them cool undisturbed for 10 to 15 minutes. They crisp up as they cool.

Sandy Sugared Walnuts or Glossy Caramelized Walnuts?

Same pan, two finishes. If you stop at the sandy stage, you get sugared walnuts: matte, crunchy, lightly sweet, and dry enough to toss into a salad without clumping. That is the recipe as written.

If you want glossy caramelized walnuts like the ones in these photos, keep stirring over medium heat for another 2 to 4 minutes after the sugar turns sandy. The crystals melt again and turn into an amber glaze. Pull the pan as soon as most of the sugar is liquid and the color is a deep honey, spread the nuts fast, and separate them before they set. This version is sweeter and harder, closer to candy, and better on desserts than on greens.

When the Walnuts Clump, Stay Wet, or Taste Bitter

• One big clump on the tray: they cooled before you separated them. Break them apart while still warm. Already set? Snap the slab into small clusters and call it walnut brittle.
• Still syrupy after 7 minutes: the heat is too low for the water to cook off. Turn it up a notch and keep stirring until the coat dries.
• Bitter or smoky taste: the nuts scorched. Cut one walnut open next time: light tan inside is right, dark brown is too far.
• Patchy coating: pieces instead of halves, or the nuts went in before the sugar fully dissolved. Give the syrup the full 2 minutes first.
• Sticky after a day: they went into the jar warm, or the kitchen is humid. Spread them on a tray in a 250°F oven for about 5 minutes, cool, and seal again.

Candied Walnuts for Salad, Cheese Boards and Gift Jars

Most people who make these want a crunchy topping for a fall salad. A handful goes a long way on an apple walnut salad or a pear salad with goat cheese and balsamic. Use the sandy version here, since the glossy one sticks to the leaves.

On the sweet side, scatter them over red wine poached pears or warm cinnamon apples, spoon them onto yogurt with a drizzle of date caramel, or toss a cup into a bowl of caramel popcorn for a party snack.

For gifts, one batch fills four ½ cup jars. They travel well because the shell is dry. Pair a jar with a few homemade salted caramels or a square of maple walnut fudge and you have a small holiday box.

Keeping the Sugar Shell Crunchy for Two Weeks

Cool the walnuts completely before sealing. Even a little warmth makes steam in the jar, and steam softens the sugar.

Store them airtight at room temperature for up to 2 weeks. For longer, freeze them flat in a zip bag for up to 3 months and let them come to room temperature in the closed bag, so condensation forms on the bag and not on the nuts. Skip the fridge. It is damp in there, and the coating turns tacky.

Candied Walnut Questions From the Stovetop

Can I make candied walnuts with brown sugar?

Yes, swap it 1 to 1. Brown sugar has more moisture, so the coat comes out darker and a little stickier, and it needs another minute or two in the pan to dry.

Do I need an oven for candied walnuts?

No. This recipe is made entirely on the stovetop in about 15 minutes. Oven versions use a different coating, usually egg white or butter with sugar, and bake low for 30 minutes or more.

Can I double the batch?

Yes, in a wide 12 inch skillet so the walnuts still sit in one layer. In a smaller pan the nuts steam instead of drying, so cook two batches back to back instead.

Does this work with pecans or almonds?

Yes, same amounts and method. Pecans cook a minute faster because they are thinner. For a crushed nut topping with a buttery crunch, see this praline crunch.
