Blackened Mahi Over Mashed Potatoes With Mushroom Wine Sauce

So many fish dishes, so little time! I had planned on adding a bunch of fish dishes for Lent, but I’m such a painfully slow typist, I’m afraid they won’t make it on here before Easter! But I think Fish on Friday is a good idea all year round anyway!

This is my tribute to The Metro Diner’s Wednesday lunch special. It’s two of my favorite things all rolled into one dish, fish and mashed potatoes! I cheated and used prepared, refrigerated mashed potatoes in this, but you can always use homemade, or substitute red beans and rice if you don’t care for the potatoes. Serve it with a salad and you’re good to go!

For the mahi:

  • 4 6oz portions mahi mahi *
  • 4 tbsp blackening spice (I used Emeril’s Essence)
  • 1 tsp dried thyme
  • 2 tbsp butter
  • 2 tbsp olive oil

For the sauce:

  • 4 tbsp butter
  • 1 half medium onion, chopped
  • 8 oz mushrooms, sliced
  • 1 clove garlic, minced
  • 4 tbsp flour
  • 3 tbsp white wine
  • 1 1/2 cup vegetable broth
  • 1/2 tsp blackening spice
  • 1/4 tsp pepper
  • dash cayenne (Optional)
  • Mashed potatoes or red beans and rice for serving

Preheat oven to 400 degrees.

Remove the mahi portions from the fridge and pat dry. Sprinkle the top of each piece evenly with 1 tbsp blackening spice and 1/4 tsp thyme.

Melt butter and olive oil in a skillet over medium-high heat. When skillet is hot, place mahi in the skillet , seasoned side down, and sear 5 minutes. Remove mahi to a foil lined baking sheet (seasoned side up) that’s been sprayed with light coating of cooking spray. Place in preheated oven for 15 minutes while preparing the sauce.

In a medium sauce pan, melt butter then add onion and garlic. Cook and stir for 5 minutes, then stir in mushrooms. Cook for 7 minutes or until mushrooms are soft. Stir in flour, and cook for 1 minute before stirring in the wine. Cook and stir for 1 minute more, then slowly stir in the vegetable broth. Season with the blackening spice, thyme, pepper, and cayenne, if desired.

Place a portion of fish over 1/2 to 3/4 cup of mashed potatoes or red beans and rice, and pour 1/2 cup of mushroom sauce over top!

*If mahi isn’t available, tilapia or swai is a good substitute.
