A Quick Blackened Mahi Mahi Recipe for Weeknight Dinner
Mahi Mahi is my go to for busy weeknights. It thaws quickly, but even if I've totally forgotten to plan ahead and it's frozen solid, dinner can still be on the table in under 30 minutes. This Blackened Mahi Mahi Recipe served with cucumber avocado salsa, however, takes it to a whole new level.
Cucumber Avocado Salsa
I came up with this delicious condiment as part of my elimination diet journey (yes, I’m as tired of being on it as you are hearing about it.) Tomatoes are on the no list and I’ve tried them a couple of times and realizing that raw tomatoes especially may not be a regular part of my diet anymore. I wanted something to go with the blackened fish to offer a little acidity and healthy fat, however, and normally this time of year that would be tomatoes, basil and olive oil. Without the tomato crutch, I found cucumbers, cilantro and avocados and set about making an alternative. It turns out, it was the perfect companion to the spicy fish. I did end up adding tomatoes for my husband and they looked so colorful, that I used that version for the photos.
Blackened Spice Blend
Blackened seasoning is a blend of spices typical in Cajun cuisine of Lousiana. It can be as spicy as you want it to be based on the amount of cayenne that you use, but the essential spices are paprika, thyme, oregano, garlic and black pepper. Salt of course is the base and I always use Himalayan Pink Salt.
How do you make Blackened Mahi with Cucumber Avocado Salsa?
Blackening is simply a term for cooking spice coated foods in a searing hot skillet. It is an incredibly easy technique that turns the spices a really dark brown or even black and adds a complex flavor to the already flavorful spices. Once you have the salsa made and the blackened seasoning mixed together, you can literally throw this dinner together in 15 minutes. You can make the blackened seasoning up in batches and keep it in a labeled jar. You will love it, so I definitely recommend you do this. The cucumber salsa can be made a day or two in advance without the avocado since it will brown, but you can add that at the last minute.
What should you serve with Blackened Mahi?
I served green beans since I had them on hand from my farmers market haul, but you can serve any vegetable you love and is in season. Typically when cucumbers are in season, you will find zucchini, beans, potatoes, eggplant, and peppers. Any of these will work for sure.
