Cajun Snapper with Mango-Avocado Salsa

The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions; to ensure that you have all the ingredients and equipment required, and to understand the steps and timings involved.

Snapper is an exotic fish with a sweet, firm, white, textured flesh and is one of the tastiest you’ll ever try! Snappers are found in warm waters around the world, and they are mainly red, or shades of red, but there are also yellow and blue snappers too.

I actually had my first taste of red snapper on a British Airways flight, way back in 1994, returning home from a vacation in Houston, Texas! And any chance I get to eat this tasty fish I will do so!

If you’re unable to find snapper where you live, you could substitute it for any other firm, white fish, such as grouper, halibut, tilapia, or cod.

Snapper is a great base for a variety of exotic flavours. The subtle flavor of the mango-avocado salsa provides a nice balance to the heat of this delicious pan-seared Cajun snapper – and it’s all ready in under 30 minutes!

Ingredients & Equipment Used In This Recipe

While most ingredients can be bought in grocery stores, for your convenience, any specialized or notable ingredients (and equipment) needed for this recipe have been listed below and linked to Amazon or other stores if available online.

It does not include staple ingredients such as oil, salt, and pepper, as you’re likely to have those in your kitchen already. The complete list of ingredients with measurements is found in the recipe card.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. You can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).
