Keto and Whole30 Rosemary Hollandaise Sauce Recipe

Last Update: September 28, 2022

If you’ve ever tried making a traditional hollandaise, you know a lot can go wrong. Your eggs could curdle, the emulsion could break, and your arm might get sore from all the whisking. So we switched things up with a simplified take on the French classic—and it’s completely Whole30-ready and keto-friendly! Fragrant rosemary, a burst of lemon, and just a dash of cayenne pepper add extra flavor. (There’s still some whisking to do, but not as much, we promise.) Drizzle this easy keto hollandaise over eggs at breakfast, spread it on sandwich bread for lunch, use as a vegetable dip, or toss with tuna or chicken salad for a light supper.

Keto and Whole30 Rosemary Hollandaise Sauce

Yield: 1 ¼cups
Active Time: 15 minutes


¼ cup ghee
3 fresh rosemary sprigs
1 cup Primal Kitchen Avocado Oil Mayo
1 teaspoon Thrive Market Organic Dijon Mustard
Juice of half a lemon
⅛ teaspoon cayenne pepper
½ teaspoon sea salt
Water, as needed


Add ghee and rosemary to a small saucepan and warm on medium heat. As the ghee melts, press rosemary into the ghee using the back of a spoon to help release its oils. Simmer until melted, about 2 to 3 minutes. Remove from heat and let rosemary steep for another 5 minutes. Discard rosemary.

In a bowl, add the mayonnaise, mustard, lemon juice, cayenne, and salt. Whisk until smooth. Drizzle the rosemary-infused ghee into the mayonnaise mixture, whisking to incorporate. If sauce is too thick for pouring, add water (2 tablespoons at a time) until loosened. If not using immediately, store in refrigerator for up to 1 week.
