Creamy spinach stuffed flounder ingredients

(Note: the full ingredients list, including measurements, is provided in the recipe card directly below.)

Flounder fillet – flounder is meaty enough to hold the stuffing, but it’s flavor is mild. Fresh fish is best, but you can also use frozen fillets.

Spinach – you can use fresh spinach, but I prefer frozen because you get so much more in one pack. 

Bell Peppers and Onions – I love using fresh veggies to pack in more nutrients and flavor to this dish.

Heavy cream– This gives the spinach that creamy texture.

Parmesan cheese –  Use freshly grated parmesan cheese. The salty, nutty flavor from the parmesan gives this dish so much life!

Lemon Juice – Citrus and fish just make a good marriage. The lemon juice brings some acid to a creamy dish to balance out the flavors.   

Tools to make your Creamy Stuffed Fish at home

You’ll need a sauté pan to prepare the spinach. My preference is stainless steal or something non-stick. In addition you’re going to need a baking pan to finish off the stuffed fish in the oven. I like this one that comes with a cover for easy storage.

How to make creamy spinach stuffed flounder

We’re baking our stuffed flounder because I think that’s the easiest approach. However, you can consider cooking this in the air fryer or on a pan with a little oil. 

In the oven this dish is done within 20 minutes. You would probably split that time in half in your air fryer.

Use a cooking thermometer to test your fish for doneness. It should read 145 degrees Fahrenheit.

If I was doing this for a special occasion a brut sparkling wine would be my go to – I think bubbles are good with everything though.
