These keto rosemary brown butter nuts only require some basic ingredients. After you follow the recipe the first time, feel free to modify the quantity of the spices to suit your taste.

Nuts - You will need 2 cups of raw nuts. I like to use pecans since they have tons of grooves for the spices to get tucked into!
Oil - Extra-virgin olive oil, walnut oil, or even toasted sesame oil will all work and lend themselves to slightly different and unique flavours!
Seasoning - You will need a combination of diced fresh rosemary as well as some salt. Feel free to adjust the recipe card to accomodate how much rosemary and salt you wish to use. You can also wait until after the nuts have roasted, taste them, and add additional spices after they have baked. Since they are still hot, the seasoning will stick to the nuts.
Sweetener - You can use any type of sweetener except for allulose as allulose will brown too quickly. My favourite sweetener to use in this recipe is Swerve Brown Sugar Substitute.

See the recipe card below for the exact quantities.

What is brown butter?

Brown butter is made by heating butter until the milk solids caramelize, imparting a golden colour and toasted, nutty flavour. The French technique is an easy way to ramp up the flavour of regular butter without adding any extra ingredients

How is brown butter different from regular butter?

Brown butter is regular butter that has been cooked just long enough to toast the milk solids found in the butter. By doing this, you create a nice nutty flavour that you just don't get with regular melted butter.

What are the best nuts for making keto spiced nuts?

To ensure that the spice mixture adheres to the nuts, my favourite nuts are ones with lots of nooks and crannies so that the spice mix has lots of places to adhere to. Pecans and walnuts are by far my favourites but almonds work well too!

So, whether you make this easy keto appetizer for friends or use these homemade keto rosemary brown butter nuts for your next fat fast, I can assure you that this keto roasted nut recipe is sure to not disappoint!
