  • Oil or butter: Roasting in fat is optional for plain walnuts and helpful when you want to add spices and seasonings.

Instructions

  • Oven: Roast in a 350-degree oven for 7 to 10 minutes.

Recipe tips and variations

  • Yield: The recipe as written makes 1 cup of toasted walnuts (enough for 4 servings, ¼ cup each). It can easily be doubled or tripled as needed.
  • Storage: Store raw and roasted walnuts for a year or more in the refrigerator or the freezer (not the pantry). They spoil easily, especially when roasted. If they smell like paint, throw them away immediately.
  • Rosemary walnuts: Heat 1 tbsp olive oil in a nonstick skillet. Add 2 cups walnuts and ½ teaspoon dried rosemary. Toast over medium-low heat until fragrant, about 8 minutes.
  • Lemon-garlic walnuts: Heat 1 tbsp olive oil or butter in a nonstick skillet. Add 2 cups walnuts, ½ teaspoon lemon zest, and 1 clove minced garlic. Toast over medium-low heat until fragrant, about 8 minutes.
  • Barbecued walnuts: Heat 1 tbsp olive oil in a nonstick skillet. Add 2 cups walnuts, ½ teaspoon cumin, ⅛ teaspoon chili powder, ⅛ teaspoon cayenne pepper, and a pinch of cloves. Toast over medium-low heat until fragrant, about 8 minutes.
  • Spiced walnuts: Heat 1 tbsp butter in a nonstick skillet. Add 2 cups walnuts, 2 tablespoons sugar, ½ teaspoon cinnamon, ⅛ teaspoon cloves, and ⅛ teaspoon allspice. Toast over medium-low heat until fragrant, about 8 minutes.

  1. I am a bit confused. You state up front, “They can go from zero to burnt in under a minute. Don’t walk away.” But when putting them in an oven preheated to 350-degrees, you give the cooking time as 7-10 minutes, which is a range of THREE minutes, which is way longer than the “less than 1 minute in which they can burn”. Having not roasted them before, how do I know when they are done since I may not recognize the right degree of smell you label “fragrant”?

    1. Hi Jimmy, oven and stovetop temperatures vary. I recommend whichever method you use to toast the walnuts, to keep an eye on them as they cook. They will become darker in color, and the nutty flavor will be more intense than when they were raw. I hope this helps! Take care! – Meggan

  2. This is the best salad Ive ever had. It is so delicious!!! I could eat it every day. And Im seriously thinking about it. Thank you for sharing. Have a great day.5 stars

    1. Hi Oliver and Levi, the oven temperature is 350 degrees. It’s in step #1 of the recipe card. Sorry about the confusion! – Meggan
