How to Make Salmon Gratin
-
Combine the thinly sliced onion and flour in a bowl, mixing them well to create a smooth, even consistency. This forms the base for a delicious creamy sauce that will elevate your gratin.
-
Heat a skillet over low heat and add the butter. Allow it to melt gently, infusing the room with a comforting aroma that will have everyone clamoring for dinner!
-
Cook the onion in the skillet until it’s translucent, no longer powdery and white—about 5 minutes. This step softens the onion and deepens its flavor, making the sauce irresistible.
-
Gradually add the milk, stirring continuously until the mixture thickens nicely—about 8-10 minutes. The creaminess will create a wonderful coating for the salmon and veggies.
-
Season with salt to taste, ensuring a well-balanced flavor profile that enhances all the delicious ingredients in your Salmon Gratin.
-
Preheat your oven to 350 degrees F, creating the perfect environment for your gratin to bubble and brown beautifully!
-
Prepare the broccoli by cutting it into bite-sized pieces. You can boil, microwave, or steam it—just aim for tender yet firm, with a vibrant green color.
-
Cut the salmon fillets into bite-sized pieces, lightly salting them to enhance their flavor. This ensures every bite is packed with that delicious ocean goodness.
-
Chop the mushrooms into quarters or smaller, depending on their size. This will help them cook evenly and integrate nicely with the other ingredients.
-
Brown the salmon pieces in a nonstick pan over medium heat for about 2-3 minutes until they have a lovely golden crust. This step locks in flavor and keeps the salmon moist.
-
Remove the salmon from the pan and sauté the mushrooms in the same pan until they’re nicely browned, seasoning with a bit of salt. This method enhances their rich, earthy taste.
-
Combine the cooked broccoli, sautéed mushrooms, and salmon in individual gratin dishes or a casserole dish, ensuring an even distribution for delightful bites every time!
-
Pour the creamy white sauce over the top and lightly stir to help bring the deliciousness to the surface—this creates a cozy layer of flavor.
-
Sprinkle generously with mozzarella or your chosen cheese blend, making sure to cover every inch for that cheesy, bubbling finish when baked.
-
Bake until the cheese is melted and golden, about 20-25 minutes. Optionally, you can pass it under the broiler for a quick moment to achieve that perfectly bronzed top!
Optional: Garnish with fresh herbs like parsley or dill for a pop of color and flavor.

• Cheese Choices: Feel free to mix cheeses! A blend of mozzarella and Gruyère creates a perfect balance of meltiness and flavor, enhancing your Salmon Gratin beautifully.
• Baking Tips: Keep an eye on the gratin during baking—different ovens vary in heat distribution. Broiling at the end gives that perfect golden finish, but don’t walk away!

Salmon Gratin with Creamy Mushroom, Broccoli, and Mozzarella Cheese Recipe FAQs
What type of salmon is best for Salmon Gratin?
Absolutely! Fresh, high-quality salmon fillets are the best choice for this dish. Look for fillets that are firm, moist, and have a vibrant pink color. If fresh isn’t available, frozen salmon can be used as well—just make sure to thaw it properly before cooking to maintain flavor and texture.
How long can I store leftover Salmon Gratin?
You can keep any leftover Salmon Gratin in an airtight container in the fridge for up to 3 days. Be sure to let it cool completely before sealing it up—this helps preserve that creamy texture you love!
Can I freeze Salmon Gratin?
Yes! To freeze your Salmon Gratin, wrap it tightly in plastic wrap, followed by aluminum foil, before putting it in the freezer. You can store it for up to 2 months. When you’re ready to enjoy, thaw it overnight in the refrigerator before reheating.
What should I do if my sauce isn’t thickening?
If your sauce isn’t thickening as expected, don’t worry! Just continue stirring it over low heat for a bit longer—sometimes it just needs a little extra time. If it’s still too thin after about 5 minutes, you can mix another tablespoon of flour with a bit of milk until smooth and then slowly whisk that into the sauce until it reaches your desired consistency.
Can I make Salmon Gratin ahead of time?
Absolutely! You can assemble your Salmon Gratin (without baking) a day in advance. Just cover it well and refrigerate. When ready to serve, bake it straight from the fridge, adding an extra 5-10 minutes to your cooking time for a delicious, effortlessly made meal.
Is Salmon Gratin safe for pets?
Generally, feeding your pets cooked salmon in small quantities is safe; however, this gratin contains dairy and seasoning that might not sit well with them. It’s best to serve plain, cooked salmon to your furry friends instead, ensuring they skip the creamy sauce!
