This delicious homemade béarnaise sauce features chopped avocados for a creamy texture and incredibly rich flavor. It matches perfectly with beef tenderloin.
Cook first 4 ingredients in a small saucepan over medium-high heat 8 to 10 minutes or until liquid is reduced to about 2 tablespoons. Cool.
Process reduced mixture, avocado, and remaining ingredients in a blender or food processor until smooth, stopping to scrape down sides. Chill up to 2 days, if desired.
