Ingredients You’ll Need

What’s great here is that the ingredients are simple but play together to create something special. Each element, from the fresh spinach to the flaky puff pastry, brings texture and delicious layers of flavor.

• Unsalted butter: Adds richness for sautéing and keeps flavors balanced without salting overkill.
• Shallot: Gives a subtle sweetness and depth without overpowering the dish.
• Garlic cloves: A little punch of aromatics that wakes up the spinach flavor.
• Fresh baby spinach: I prefer baby spinach because it cooks down nicely and stays tender.
• Kosher salt and pepper: Essential for seasoning the fish and veggies perfectly.
• Cream cheese: This makes the spinach luxuriously creamy and binds everything together.
• Parmesan cheese: Adds a nutty, savory touch that complements the salmon beautifully.
• Freshly squeezed lemon juice: Brightens and lifts the whole dish, balancing the richness perfectly.
• Salmon filet (2-pound, 1-inch thick): The star of the show — make sure it’s fresh and skinless for ease of wrapping.
• Puff pastry sheet: Thawed if frozen; it wraps the salmon and greens in a gorgeously flaky crust.
• Egg + water (for egg wash): Gives that golden, glossy finish you can’t resist.

Variations

I love swapping things up depending on the season or what’s in the fridge. Don’t be afraid to make this your own by adjusting flavors or adding your favorite extras—it’s so versatile!

• Herby twist: I sometimes add fresh dill or tarragon to the spinach mixture for an herbal lift that pairs beautifully with salmon.
• Cheese swap: If you’re not a cream cheese fan, goat cheese or ricotta can work nicely for a different creaminess.
• Spinach alternatives: Kale or Swiss chard can be used if you want a more earthy flavor; just cook them longer for tenderness.
• Make it spicy: A pinch of red pepper flakes in the spinach mix adds a subtle warmth my family adores.

How to Make Salmon en Croûte with Spinach and Puff Pastry Recipe

Step 1: Sauté Your Shallots, Garlic, and Spinach to Creamy Perfection

Start by melting that butter over medium heat in a large skillet—it’s where all your flavor begins. Add the diced shallot and minced garlic along with a generous pinch of salt and pepper. Cook for about 2 to 3 minutes until they soften and smell amazing. Then, toss in the fresh baby spinach and stir it frequently until all the leaves have wilted down.

Here’s a trick I discovered: once the spinach is wilted, stir in the cream cheese right away so it melts smoothly, creating a velvety base. Follow with parmesan cheese and finish with freshly squeezed lemon juice for that bright, fresh pop.

Step 2: Season and Prepare the Salmon and Puff Pastry Bed

Lay your sheet of puff pastry on a baking sheet—don’t worry about cutting it down, it’s easier to wrap the fish if you have some edges to fold. Spoon a layer of the creamed spinach right in the center; aim for about the size of your salmon filet or just a bit smaller. This bed keeps the salmon moist and adds that decadent creaminess.

Next, season your salmon all over with kosher salt and freshly ground pepper. Trust me, seasoning every layer pays off in the final flavor punch!

Step 3: Wrap It Up Like a Pro and Get That Perfect Golden Crust

Place the salmon directly on top of the spinach bed on your puff pastry. Now comes the fun part—fold the pastry edges carefully over the salmon to seal it completely. Don’t rush! Make sure there are no gaps where the juices could leak out. I usually flip it over so the seam is on the bottom because it makes for a prettier presentation.

Brush the entire pastry parcel with your egg wash—that combo of beaten egg and a teaspoon of water is what gives the crust that irresistible glossy, golden finish. Before popping it in the oven, score the top lightly a few times with a sharp knife to let steam escape and give a professional bakery look.

Step 4: Bake Until Golden, Crisp, and Absolutely Mouthwatering

Bake your salmon en croûte at 425°F for 25 to 30 minutes. Keep an eye on it—the pastry should puff up and turn golden brown with a crisp texture. When it’s out of the oven, give it at least 5 to 10 minutes to rest. This helps the juices redistribute and allows the salmon to finish cooking gently. Then, slice and get ready for compliments!

How to Serve Salmon en Croûte with Spinach and Puff Pastry Recipe

Garnishes

I usually keep garnishes simple to let the dish shine, but a sprinkle of chopped fresh dill or a few lemon wedges on the side add a fresh, inviting touch. A light drizzle of crème fraîche or a dollop of herbed yogurt can also elevate the experience.

Side Dishes

My go-to sides for Salmon en Croûte include a crisp green salad or some roasted baby potatoes tossed with olive oil and fresh herbs. Another favorite is simple steamed asparagus or green beans seasoned with a squeeze of lemon to keep everything bright and fresh.

Creative Ways to Present

For special occasions, I’ve served this salmon en croûte sliced into elegant individual portions on a wooden board with a sprinkle of microgreens. You can also turn it into a stunning centerpiece by slicing and fanning pieces on a platter surrounded by lemon wedges and edible flowers—it’s a guaranteed crowd-pleaser.

Make Ahead and Storage

Storing Leftovers

If you have leftovers (which doesn’t happen often in my house!), wrap them tightly in plastic wrap or foil and keep them in an airtight container in the fridge for up to 2 days. The pastry will soften a bit but still taste delicious the next day.

Freezing

I’ve had success freezing the assembled but unbaked salmon en croûte. Wrap tightly in plastic and foil, then freeze for up to 1 month. When ready, bake it straight from frozen—just add a few extra minutes to the baking time. This is a great option for meal prep or entertaining last minute.

Reheating

Reheat gently in a preheated 350°F oven for 10-15 minutes to crisp the puff pastry again without drying out the salmon. Avoid microwaving if you want to keep that flaky pastry texture intact.
