Why you'll love it

Fish florentine, or Poisson a la Florentine, is a traditional French dish consisting of white fish topped with creamy spinach sauce and breadcrumbs.

In its original form, it's very close to fitting a ketogenic diet. With a couple of small adjustments, this fish recipe will make a wonderful addition to your meal plan.

I love this recipe because it's quick, delicious, and versatile. It's perfect to serve to friends and family for a special occasion or to be enjoyed on an average weeknight.

You can also very easily make this recipe your own with modern variations or traditional methods, depending on your preference.

Ingredients

ingredients for the fish florentine

While this dish looks impressive, it's deceivingly simple. Here's what goes into this fresh fish dish:

Cod fillets

The base of this recipe is cod. Cod is a wonderful white fish that is mild in flavor with a firm, flaky texture.

It's also fair in price and widely available!

Dairy

Part of what makes this recipe so delicious is all of its dairy components.

Fish florentine includes high-fat ingredients such as heavy whipping cream, butter, and parmesan cheese.

Vegetables

Onion, garlic, and spinach add flavor, color, and nutrition to this dish.

Pork rind crumbs

For a keto breadcrumb alternative, pork rind crumbs are the answer!

Made from ground pork rinds, these breadcrumbs are naturally gluten-free, carb-free, and suitable for a keto diet.

Try out this recipe for homemade keto breadcrumbs.

Seasoning

While these ingredients are delicious in their own right, we bump it up a little further with some flavor-enhancing seasonings.

Add salt, black pepper, and chicken stock for a simple yet effective seasoning.

Tips

  • Saute garlic after your onions have already cooked down. This will prevent your garlic from burning and give your dish a burnt garlic taste.
  • You can use fresh or frozen spinach. If you use frozen, make sure it has been completely thawed and well-drained before adding it to your sauce. You don't want your sauce to be watered down.

Instructions

Fish florentine is one of my favorite recipes to serve because it's keto-friendly, packed with nutrients, and totally delicious.

Here is a bit of information about how I make this decadent, creamy fish florentine.

Initial prep

First, preheat your oven to 375°F. Then, as it heats, place your fish fillets in a casserole dish and season them with salt and pepper.

Flavor your butter

Add two tablespoons of butter to a large skillet over medium heat.

Flavor your butter by adding your chopped onion to the skillet and saute until they are soft and fragrant.

Add your garlic and saute for an additional thirty seconds.

Create your sauce

Add your greens

The final touch to your fish florentine sauce is spinach! Add frozen spinach to your skillet and stir until it has cooked down.

Season your spinach mixture with salt and pepper to taste.

Make your breadcrumbs

To make keto-friendly breadcrumbs, combine your pork rind crumbs with a quarter cup of parmesan cheese in a bowl.

This addition will bump up the fat content of the dish and make it super tasty.

Bake and serve

Pour your creamed spinach mixture onto the prepared fish fillets.

Then, sprinkle your keto breadcrumbs overtop.

Serving suggestions

This recipe would be great to serve at your next family dinner. As an appetizer, try stuffed portobello mushrooms with spinach and artichoke, Zuppa Toscana soup, or an impressive keto charcuterie board.

You can also serve it alongside oven-roasted asparagus, green beans almondine, or cilantro lime cauliflower rice.

If you're hosting and want to make a real impression, follow your dish up with a scrumptious dessert. Try a light and fluffy almond flour cake, white chocolate pudding, or keto chocolate biscotti to round off your meal.

Variations

Cooking is all about getting creative and having fun; feel free to make this recipe your own!

Here are a few variation ideas:

  • Substitute cod for halibut, grouper, or another mild, white fish.
  • Add extra greens like kale for a nutrition boost!
  • Season your pork rind breadcrumbs for extra flavor.
  • Include fresh lemon juice in your sauce for a touch of acid.
  • Try coconut milk or cream cheese in your sauce to add depth of flavor.

FAQs

These are a few common questions I get about my keto fish florentine recipe. If you don't see your question answered, please leave it for me in the comments down below.

What is a Florentine sauce made of?

Florentine sauce is quite simple to make. Traditionally, it is made from heavy cream, butter, garlic, white wine, and spinach.

Is fish keto-approved?

Fish is keto-friendly; it's packed with protein and nutrients and is low in carbs. Plus, fish like salmon are practically carb free!
Remember to research net carbs before you choose a fish. While most white varieties are low in carbs, some fish have higher carb counts.

Is halibut a white fish?

It is. Halibut is a delicious, flaky, white fish that would work well in this fish florentine recipe!

  • Fish Tacos are filled with healthy fried cod and pico for a fresh and delicious meal.
  • Sheet Pan Pizza with Fish, Shrimp, and Scallops is a seafoodie's delight! Enjoy keto pizza with mouth-watering flavor.
