Step-by-Step Instructions
Step 1: Prepare the Broccoli
Blanch the Broccoli florets in salted boiling water for 3 minutes until bright green and slightly tender. Immediately transfer to an ice bath to stop the cooking process. This technique preserves the vibrant color and ensures a perfect al dente texture in your final dish. Drain thoroughly and pat dry to prevent a watery gratin.
Step 2: Prepare the Salmon
Season salmon cubes with salt, pepper, and a light drizzle of olive oil. For extra flavor depth, add a pinch of lemon zest. Let the salmon sit at room temperature for 10 minutes while preparing other components – this prevents it from becoming tough during baking.
Step 3: Create the Perfect Béchamel Base
In a medium saucepan over medium heat, melt butter and sauté shallots for 2-3 minutes until translucent. Add minced garlic and cook for another 30 seconds until fragrant. Sprinkle flour over the mixture and whisk continuously for 1-2 minutes to cook out the raw flour taste. This roux is the secret to a smooth, lump-free sauce.
Step 4: Develop the Creamy Sauce
Gradually whisk in the cream, adding it in small increments to prevent lumps. Continue whisking until the sauce thickens enough to coat the back of a spoon (about 5 minutes). Add nutmeg, thyme, salt, and pepper. Fold in half of each cheese, saving the rest for topping. The gradual addition of liquid ensures a silky-smooth texture every time.
Step 5: Assemble the Gratin
Preheat your oven to 375°F (190°C). In a 9×13-inch baking dish, arrange the blanched Broccoli and salmon pieces evenly. Pour the creamy sauce over the ingredients, ensuring everything is well coated. The distribution of ingredients impacts both flavor and aesthetic appeal.
Step 6: Create the Perfect Topping
Combine remaining cheeses with breadcrumbs and olive oil in a small bowl. Sprinkle this mixture evenly over the gratin. This creates a golden, crunchy crust that contrasts beautifully with the creamy interior.
Step 7: Bake to Perfection
Bake uncovered for 25-30 minutes until the top is golden brown and the sauce is bubbling around the edges. For an extra crispy top, broil for the final 2 minutes, watching carefully to prevent burning. Allow to rest for 5-10 minutes before serving to let the flavors meld and the sauce set.

- Skipping the roux step (causes sauce separation)
- Using cold salmon straight from refrigerator (creates uneven cooking)
- Rushing the sauce thickening process (produces lumps)
- Overcrowding the baking dish (prevents proper heat distribution)
- Slicing salmon too thin (causes it to overcook and dry out)
Storing Tips for the Recipe
This Broccoli and Salmon Gratin can be refrigerated for up to 3 days in an airtight container. For best results when reheating, cover with foil and warm in a 325°F oven for 15-20 minutes until heated through, removing the foil for the last 5 minutes.
You can also prepare components ahead of time: blanch the broccoli and prepare the sauce up to 24 hours in advance. Store separately in the refrigerator and assemble just before baking, adding an extra 5-10 minutes to the baking time.

FAQs
Can I use frozen broccoli instead of fresh?
Yes, but thaw completely and pat dry before using. Reduce blanching time to 1 minute as frozen broccoli is partially cooked.
Is it possible to make this dish dairy-free?
Absolutely! Substitute coconut cream for heavy cream and use nutritional yeast instead of cheese for a similar flavor profile.
Can I prepare this gratin in advance?
Yes, assemble up to 24 hours ahead and refrigerate. Add 10-15 minutes to the baking time when cooking from cold.
What’s the best type of salmon to use?
Wild-caught salmon like Sockeye or Coho works best due to firmer texture and richer flavor, but any salmon variety will work.
Can I add other vegetables to this gratin?
Certainly! Cauliflower, asparagus, or spinach make excellent additions or substitutions. Adjust blanching times accordingly for different vegetables.
