The Ultimate Avocado Sauce for Fish Tacos

Maybe your specialty is spicy catfish tacos. Maybe it’s battered tilapia. Maybe it’s just fish sticks in a tortilla. But no matter what the catch of the day is, a taco just isn’t a taco without the perfect sauce. And does anything beat avocado sauce?

Many traditional sauce recipes use spreads that contain saturated fats. Luckily, this homemade avocado sauce for fish tacos is a superb substitute. Most of the fat in avocados is unsaturated (monounsaturated and poly saturated fats), making avocados a great replacement for foods high in saturated fat. You get the same creamy texture, plus a brilliant green color. Bonus: This sauce is gluten free!

Avocado Sauce for Fish Tacos

Makes 5 servings.


  • 1 ripe Avocado From Mexico
  • 1/2 c. cilantro, loosely packed
  • 1 clove of garlic, minced or chopped
  • Juice of one lime
  • 1/3 c. low-fat plain yogurt
  • Salt and pepper to taste
  • 1 jalapeño (optional)


  1. Prepare all ingredients. Carefully cut open the avocado, lengthwise, with a sharp knife. Scoop out the flesh with a shallow spoon into a food processor or blender. Mince or chop the garlic clove into small pieces. Tightly chop the jalapeño (if using). Remove seeds to lessen the heat. Loosely chop cilantro, up to 1/2 cup. Do not pack it down. Combine ingredients in the food processor.
  2. Blend. In 10-second intervals, blend the mixture until creamy. Taste-test in between blends. Too thick? Add more lime juice or a sprinkle of water. Too runny? Add more avocado or yogurt to thicken the mixture.
  3. Get presentation points. If spooning into individual ramekins for guests, sprinkle a few cilantro leaves over the top of each serving. If drizzling the avocado sauce over fish tacos, use the “piping-bag” method. Place the sauce in a sandwich bag. Push the air out of the bag and seal. Twist the bag from the top down to create pressure at one corner. Cut a spout in that corner with scissors and drizzle the sauce in a zigzag pattern over the mouth of the tacos.
  4. Store. Avocado naturally oxidizes when exposed to air and turns brown. Keep your sauce a brilliant green by storing it in an air-tight container with a layer of plastic wrap inside, touching the top surface of the mixture. This recipe is good for about two days but tastes best when served fresh.
