Salmon Lasagna Ingredients
For the Filling

- Canned or Fresh Salmon – The main protein source; use canned for convenience or fresh for a richer flavor.
For the Béchamel Sauce
- All-Purpose Flour – Used to thicken the béchamel sauce; substitute with gluten-free flour for a gluten-free option.
- Milk – Forms the base of the béchamel sauce; alter with plant-based milk for dairy-free variations.
- Dijon Mustard – Adds a subtle tanginess to the béchamel; adjust quantity to taste based on preference.
- Lemon Zest – Brightens flavors; use fresh zest for the best flavor.
- Dill – Fresh herb for added flavor; can substitute with parsley if preferred.
- Grated Parmesan – Adds savory depth to the sauce; use nutritional yeast as a dairy-free alternative.
- Nutmeg – Offers warm flavor to béchamel; optional based on taste.

Step‑by‑Step Instructions for Salmon Lasagna
Step 1: Prepare the Filling
Melt 2 tablespoons of unsalted butter in a large skillet over low heat. Add sliced leeks and sauté for 5–10 minutes until they soften and become translucent. Stir in the drained fresh or thawed frozen spinach, sprinkle with salt, and cook until just wilted. Drain any excess moisture using a sieve to prevent a watery lasagna.
Step 2: Make the Béchamel Sauce
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Whisk in 4 tablespoons of all-purpose flour to form a roux, cooking for about 2 minutes until bubbling. Gradually whisk in 2 cups of milk, stirring continuously for 5–7 minutes until the sauce thickens and coats the back of a spoon. Stir in Dijon mustard, dill, lemon zest, nutmeg (if using), and half of the grated Parmesan, seasoning to taste.
Step 3: Assemble the Lasagna
Preheat your oven to 350°F (180°C). In an ovenproof dish, spread a thin layer of béchamel sauce on the bottom, then layer the no-pre-cook lasagna sheets on top. Add a layer of flaked salmon, followed by a generous portion of the spinach filling, and then more béchamel. Repeat the layers, finishing with a top layer of béchamel sauce and the remaining grated Parmesan.
Step 4: Bake the Lasagna
Cover the assembled Salmon Lasagna with aluminum foil and place it in the preheated oven. Bake for 25 minutes, or until the sauce is bubbling. For an extra golden top, remove the foil and broil on high for an additional 5 minutes, keeping a close eye to prevent burning.
Step 5: Serve the Dish
Once out of the oven, allow the lasagna to cool for about 10 minutes for easier slicing and to let the flavors meld together. Cut into squares and serve with a side salad or steamed vegetables for a delightful and comforting meal that’s perfect for any night of the week.

How to Store and Freeze Salmon Lasagna

Expert Tips for Salmon Lasagna
