How this recipe became a weeknight staple for me

I remember the first time I made this dish—honestly, it was out of sheer desperation to use up a bag of spinach wilting in my fridge! I had some salmon fillets in the freezer and a pint of half & half that was about to expire. It was one of those “throw it all in the pan and hope for the best” nights. But as soon as I took that first bite, I knew I’d stumbled onto something magical. The creamy sauce, the earthy mushrooms, and the bright pop of lemon paired with the rich salmon—it all just worked. Since then, this dish has become one of my go-to recipes for when I want something quick but impressive. And yes, I still think about that random bag of spinach that started it all.

Where does Florentine come from? A little backstory

Florentine dishes are inspired by the flavors of Florence, Italy, where spinach is a star ingredient. In classic Italian cuisine, anything “Florentine” typically involves spinach and a creamy sauce. While this salmon Florentine recipe isn’t exactly traditional, it takes inspiration from those comforting, spinach-filled flavors. Over time, the concept of Florentine has become a popular way to elevate all kinds of dishes, from chicken to pasta. With its balance of creamy and fresh ingredients, it’s easy to see why Florentine-style cooking has become such a beloved technique.

Let’s talk ingredients: The stars of the dish

The beauty of this recipe is its simplicity. Each ingredient plays a key role in bringing the dish together:

Salmon fillets: These are the heart of the dish, offering a rich, flaky texture and bold flavor. Look for salmon with a vibrant orange-pink color and no overly fishy smell. If fresh salmon isn’t available, high-quality frozen fillets work well too.
Baby spinach: The star “Florentine” ingredient! Fresh spinach wilts beautifully into the creamy sauce. In a pinch, frozen spinach can work—just make sure to thaw and squeeze out the excess water.
Mushrooms: Sliced mushrooms add an earthy depth of flavor. I prefer cremini or button mushrooms, but feel free to experiment with shiitake or even oyster mushrooms.
Half & half: This creates the creamy base without being as heavy as cream. If you want a lighter option, you can substitute with whole milk and a bit more cornstarch.
Parmesan cheese: Just a couple of tablespoons add a nutty richness that ties the sauce together. Grate it fresh if you can—it’s worth it!
Lemon juice: A splash of lemon cuts through the richness and brightens the dish. Fresh lemon juice makes all the difference here!
Seasonings: Red chili flakes bring a gentle kick, while salt enhances all the other flavors. You can adjust the spice level to your liking.

Kitchen gear: What you’ll need to make this dish

Don’t worry—this recipe doesn’t require any fancy gadgets. Here’s what I use:

A large nonstick skillet: Perfect for searing the salmon and making the sauce in one pan. If you don’t have nonstick, a well-seasoned cast iron pan works too.
A spatula: Use a sturdy spatula for flipping the salmon without breaking it.
A whisk: To mix the cornstarch into the half & half smoothly. A fork can work in a pinch, but a whisk makes life easier.
Sharp knife and cutting board: For chopping onions, garlic, and slicing mushrooms.
Measuring spoons and cups: Accuracy matters when working with cornstarch and seasonings!

Step-by-step: How to make creamy salmon Florentine

Making this dish is easier than you think! Here’s how it all comes together:

Sear the salmon
Start by heating the vegetable oil in a large nonstick pan over medium-high heat. While it’s heating, sprinkle the salmon fillets with salt and red chili flakes. Once the pan is hot, sear the salmon for about 5 minutes per side, until it’s cooked through and develops a golden crust. Transfer the fillets to a plate and set them aside. (Pro tip: Don’t overcrowd the pan or the salmon won’t brown properly.)
Sauté the aromatics and mushrooms
In the same pan, toss in the finely chopped onion. Cook until it turns translucent, stirring occasionally so it doesn’t burn. Add the minced garlic and cook for about 30 seconds, just until fragrant. Then, add the sliced mushrooms and sauté until they release their moisture and turn golden brown.
Make the creamy sauce
While the mushrooms are cooking, dissolve the cornstarch in the half & half. Pour this mixture into the pan, stirring as you go, and add the Parmesan cheese. Bring it to a gentle simmer, allowing the sauce to thicken slightly. You’ll know it’s ready when it coats the back of a spoon.
Add the spinach and season
Toss in the baby spinach and stir until it wilts into the sauce. Season with salt, red chili flakes, and a tablespoon of fresh lemon juice. Give everything a good stir to combine the flavors.
Finish with the salmon
Finally, nestle the seared salmon fillets back into the pan, spooning some sauce over the top. Let it all simmer together for a minute or two before serving. The sauce will keep the salmon moist and flavorful!

Variations and adaptations to try

This recipe is super versatile, and you can tweak it to suit your taste or dietary needs:

Make it dairy-free: Replace the half & half with coconut milk and skip the Parmesan. The sauce will still be creamy and delicious!
Low-carb option: Serve the salmon over cauliflower rice or zucchini noodles for a keto-friendly meal.
Add some protein: Stir in a handful of cooked shrimp or scallops for an extra seafood twist.
Vegetarian version: Swap the salmon for thick slices of roasted cauliflower or grilled tofu. The sauce pairs beautifully with both.
Seasonal twist: In summer, try adding fresh cherry tomatoes to the sauce for a burst of sweetness. In fall, use kale instead of spinach for a heartier texture.

How to serve and make it look amazing

Presentation is key when serving this dish! Place the salmon fillet on a plate and spoon the Florentine sauce generously over the top. Add a sprinkle of fresh Parmesan and a few cracks of black pepper for a finishing touch. Pair it with steamed broccoli, roasted asparagus, or even a simple side salad for a complete meal. If you’re feeling fancy, serve it with a slice of crusty bread to soak up that dreamy sauce.

Perfect drink pairings for salmon Florentine

Here are a few great choices:

Sparkling water with lemon: The zesty citrus complements the dish’s lemony notes beautifully.
Iced green tea: Its light, refreshing flavor balances the richness of the sauce.
Cucumber-mint lemonade: This crisp, herbaceous drink adds a fresh twist to your meal.

Storing leftovers and reheating tips

If you have leftovers, store the salmon and sauce in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm it in a skillet over low heat, adding a splash of milk or water to loosen the sauce. Avoid microwaving, as it can make the salmon dry and the sauce too thick. Trust me, it’s worth the extra few minutes on the stovetop!

Scaling the recipe for a crowd (or just yourself)

This recipe makes four servings, but it’s easy to adjust. For two people, halve the ingredients and use a smaller pan. For a crowd, double the recipe and cook the salmon in batches to avoid overcrowding the pan. Just remember, the sauce thickens as it cools, so keep it warm until serving.

Common issues and how to avoid them

Sauce too thick? Add a splash of milk or water to thin it out.
Salmon falling apart? Make sure your pan is properly preheated before adding the fillets.
Too bland? Don’t skimp on the lemon juice and Parmesan—they’re key to balancing the flavors.

Whether you’re a seasoned cook or a beginner, you’ll love how quickly it comes together and how delicious it tastes. Feel free to experiment with the variations and make it your own—I promise, it’ll turn out amazing every time!
