How to Make Roasted Salted Walnuts: Step-by-Step
Now let’s get into the actual process of how to make roasted salted walnuts from scratch.
It takes less than 20 minutes from start to finish, and most of that is hands-off baking time.
1. Gather Your Ingredients
To make roasted salted walnuts, you’ll need two cups of raw walnut halves, one tablespoon of oil, and half a teaspoon of fine salt.
You can also add a pinch of black pepper, paprika, or cinnamon if you want flavored roasted salted walnuts.
2. Preheat and Prepare
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
This ensures your roasted salted walnuts won’t stick and clean-up is a breeze.
3. Toss the Walnuts
In a bowl, combine the walnuts with oil and salt, stirring until every piece is evenly coated.
This step is crucial for making roasted salted walnuts where the seasoning is balanced in every bite.
4. Spread and Bake
Spread the coated walnuts in a single layer on your baking sheet.
Bake for 8 to 10 minutes, stirring halfway through, until they smell nutty and look slightly darker.
Remember, walnuts burn quickly, so keep an eye on them when you make roasted salted walnuts.
5. Cool and Store
Let your roasted salted walnuts cool completely on the baking sheet—they’ll crisp up as they cool.
Store them in an airtight container at room temperature for up to two weeks.
Now you know how to make roasted salted walnuts that stay fresh and crunchy.
Tips for Perfect Roasted Salted Walnuts
Even though making roasted salted walnuts is easy, a few tips can take yours from good to great.
1. Don’t Skip the Stir
Stirring halfway through roasting ensures even browning, so your roasted salted walnuts don’t have burnt spots.
2. Salt After Roasting (Optional)
If you’re worried about salt burning, you can roast the walnuts with oil only, then toss with salt immediately after they come out of the oven.
This method still gives you delicious roasted salted walnuts with perfect seasoning.
3. Watch the Time
Ovens vary, so start checking your walnuts at the 7-minute mark when you make roasted salted walnuts.
They’re done when they’re fragrant and lightly browned—not dark brown.
4. Try Different Salts
Flaky sea salt adds a nice crunch to roasted salted walnuts, while truffle salt makes them feel gourmet.
Experiment to find your favorite version of roasted salted walnuts.
5. Store Properly
Always cool roasted salted walnuts completely before storing, or trapped steam will make them soggy.
If you want them to last longer, keep roasted salted walnuts in the fridge for up to three months.
