What Is Fish Florentine?

Fish Florentine is a classic seafood dish that features white fish fillets served with a creamy spinach sauce. The term Florentine refers to dishes prepared in the style of Florence, Italy, which typically include spinach and a rich, buttery sauce. While this style is often associated with eggs (Eggs Florentine) or chicken (Chicken Florentine), it also pairs exceptionally well with delicate white fish.

The Origin of Florentine-Style Dishes

The Florentine cooking style traces its roots back to Catherine de’ Medici, an Italian noblewoman from Florence who married King Henry II of France in the 16th century. Legend has it that she introduced spinach-based dishes to French cuisine, inspiring the Florentine-style recipes we know today. Over time, chefs began incorporating creamy sauces, cheese, and proteins like fish or chicken to enhance these dishes.

Why White Fish Works Best for Florentine Recipes

The mild, flaky texture of white fish fillets makes them an excellent base for Florentine-style cooking. Some of the best fish choices include:
Cod – Mild, flaky, and holds up well in creamy sauces.
Tilapia – A budget-friendly option with a mild taste.
Haddock – A slightly firmer texture that absorbs flavors beautifully.
Halibut or Sole – Great for a more delicate, melt-in-your-mouth experience.

The rich spinach sauce provides a smooth, velvety contrast to the light, flaky fish, creating a perfectly balanced dish.

Garlic – Enhances the sauce with a rich, savory aroma and deep flavor. Freshly minced garlic works best.
Butter or Olive Oil – Used for sautéing the garlic and spinach, adding richness to the dish.
Fresh Spinach – The star ingredient of Florentine-style dishes. It wilts down beautifully into the creamy sauce.
Heavy Cream – Adds a rich, smooth, and creamy consistency to the sauce.

White Wine – Provides acidity and a subtle depth of flavor (optional but recommended).

Step-by-Step Guide: How to Make Fish Florentine

Making Fish Florentine is easier than you think! This one-pan recipe ensures a flavorful dish with minimal cleanup. Below is a detailed, step-by-step guide to help you create a perfectly cooked fish with a rich and creamy spinach sauce every time.

Step 1: Prepare the Fish

The key to a delicious Fish Florentine is using fresh, high-quality white fish fillets and seasoning them properly.

Pat the Fish Dry – Use paper towels to remove excess moisture to ensure even cooking.
Season Generously – Sprinkle salt, black pepper, and Italian seasoning over both sides of the fillets.
Dredge Lightly (Optional) – Lightly coat the fish in flour or cornstarch for a subtle crispiness when searing.

Cooking the Fish:

Heat a large pan over medium heat and add butter or olive oil.
Sear the fish fillets for 2-3 minutes per side until they develop a light golden crust. (They don’t need to be fully cooked yet, as they’ll finish cooking in the sauce.)
Remove the fish from the pan and set it aside on a plate while you make the creamy spinach sauce.

Pro Tip: Be gentle when flipping the fillets to keep them from breaking apart.

Step 2: Make the Creamy Spinach Sauce

The Florentine sauce is what makes this dish truly special. It’s rich, garlicky, and packed with flavor!

How to Make the Sauce:

Sauté the Garlic & Spinach

In the same pan, add a bit more butter or olive oil.
Stir in the minced garlic and cook for about 30 seconds until it releases its aroma.
Toss in fresh spinach and cook until it wilts down, about 2-3 minutes.

Deglaze the Pan (Optional but Recommended)

Pour in a splash of white wine and let it simmer for 1 minute to enhance the depth of flavor.

Add the Cream & Cheese

Stir in heavy cream and let it simmer for 2-3 minutes, allowing it to thicken slightly.
Sprinkle in Parmesan cheese and stir until melted and combined.
If needed, use a teaspoon of cornstarch mixed with water to thicken the sauce.

Adjust Seasoning

Taste and add salt, pepper, and a pinch of nutmeg for extra depth.
Add red pepper flakes if you like a bit of spice.

Pro Tip: If the sauce becomes too thick, add a splash of milk or broth to loosen it up.

Step 3: Combine and Cook Everything Together

With the sauce prepared, it’s time to combine all the ingredients!

Return the Fish to the Pan

Nestle the seared fish fillets back into the pan, spooning some of the creamy spinach sauce over the top.

Let the Fish Simmer

Cover the pan and let the fish simmer for 3-5 minutes over low heat until it’s fully cooked and flaky.

Final Touches

Sprinkle extra Parmesan cheese on top.
(Optional) Add a handful of shredded mozzarella and let it melt for a cheesy crust.

Pro Tip: The fish is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).

Step 4: Serve and Enjoy!

Your Fish Florentine is now ready to serve! Here are some great serving ideas:

With a Side of Rice – Garlic butter rice or creamy risotto complement the dish perfectly.
Over Mashed Potatoes – A great option for a comforting meal.
With Crusty Bread – Perfect for soaking up the extra creamy sauce.
Alongside Roasted Veggies – A light and nutritious pairing.

Making Fish Florentine is simple, but a few expert tips can take your dish from good to restaurant-quality. Here are the best tips and tricks to ensure your fish is perfectly cooked and your sauce is creamy and flavorful every time.

1. Choosing the Best Fish for Florentine

The type of fish you use can greatly impact the taste and texture of the dish. Follow these tips for the best results:

Opt for Mild, Flaky White Fish – Cod, tilapia, haddock, halibut, or sole work best. These types of fish absorb the creamy sauce beautifully without overpowering it.
Use Fresh or High-Quality Frozen Fish – If using frozen fish, thaw it completely and pat it dry to prevent excess water from diluting the sauce.
Skinless and Boneless Fillets are Best – This makes cooking easier and ensures a smooth, enjoyable bite.

Pro Tip: If you prefer a firmer texture, go for haddock or halibut. If you like a more delicate, buttery texture, opt for sole or cod.

2. How to Cook the Fish Perfectly

Overcooking is one of the biggest mistakes when making Fish Florentine. Follow these tips to achieve tender, flaky fish every time:

Sear on Medium Heat – Cooking the fish too fast on high heat can make it dry. Medium heat allows for even cooking.
Don’t Overcook – The fish is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).
Let the Fish Rest After Cooking – This helps retain moisture and keeps it tender and juicy.

Pro Tip: If your fish starts to break apart, don’t worry! The creamy sauce will still hold everything together.

3. Making the Creamiest Florentine Sauce

The Florentine sauce is the heart of this dish, and getting the right consistency and flavor balance is key.

Use Heavy Cream for a Velvety Texture – This creates a rich, luscious sauce. If you prefer a lighter option, you can use half-and-half or coconut milk.
Don’t Skimp on Parmesan – It adds umami, saltiness, and depth of flavor. Always use freshly grated Parmesan for the best results.
Deglaze with White Wine – A splash of dry white wine enhances the flavors of the sauce. If you don’t want to use wine, a little chicken broth works as a substitute.
Season in Layers – Season each step of the cooking process rather than just at the end. This ensures a well-balanced and flavorful sauce.

Pro Tip: If the sauce becomes too thick, add a small splash of milk or broth to loosen it up. If it’s too thin, simmer for a few extra minutes or add a cornstarch slurry (1 teaspoon cornstarch + 1 teaspoon water).

4. Avoiding Common Mistakes

Here are some common mistakes and tips to prevent them:

Adding Too Much Spinach at Once – Fresh spinach wilts quickly. Introduce it in small portions to guarantee even cooking.
Skipping the Garlic & Onion – These aromatics build the foundation of the sauce’s flavor.
Cooking the Fish in the Sauce for Too Long – Once the fish is returned to the pan, let it simmer just until cooked through. Overcooking can make it fall apart.
Not Tasting & Adjusting the Seasoning – The sauce needs balanced saltiness, richness, and a touch of acidity. Season with salt, pepper, or a splash of lemon juice to taste, if necessary.

Pro Tip: If the sauce tastes too rich, a pinch of nutmeg or a splash of lemon juice can help cut through the heaviness.

5. Serving and Storing Fish Florentine

To make the most of your delicious creamy fish dish, follow these serving and storage tips:

Best Sides to Serve With Fish Florentine

Garlic butter rice – A great way to soak up the creamy sauce.
Mashed potatoes – Adds extra comfort to the dish.
Crusty bread – Great for dipping into the flavorful sauce.
Steamed or roasted vegetables – A healthy, low-carb pairing.

How to Store Leftovers

Refrigeration: Keep in an airtight container and refrigerate for up to 2 days.
Reheating: Gently warm over low heat on the stove, adding a splash of broth or milk to keep the sauce creamy.
Freezing: Not advised, as the creamy sauce may separate when thawed.

Pro Tip: If reheating in the microwave, use short 30-second intervals to prevent overcooking the fish.

Fish Florentine is already a great low-carb meal, but you can make a few tweaks to make it fully keto-friendly:

Low-Carb Thickening Options:
Cream Cheese – Adds thickness and richness without using flour.
Xanthan Gum – A tiny pinch (⅛ teaspoon) thickens the sauce without adding carbs.
Reduce the Cream – Simmer the sauce longer to naturally thicken it without any thickeners.

Keto-Friendly Side Dish Ideas:

Cauliflower Mash – A creamy, buttery substitute for mashed potatoes.
Zucchini Noodles (Zoodles) – A great alternative to traditional pasta.

Vegetable Add-Ins:
