Step-by-Step
Instructions
1.
Prepare the Oven
Preheat the oven to 200°C (400°F).
Lightly grease a baking dish.
2.
Season the Salmon
Cut salmon into large chunks.
Season with salt, black pepper,
garlic powder, and paprika.
Set aside.
3.
Prepare the Broccoli
Blanch broccoli florets in boiling
water for 2 minutes.
Drain and rinse with cold water.
This keeps the broccoli vibrant and
slightly crisp.
4.
Make the Cream Sauce
In a saucepan, melt butter over
medium heat.
Add garlic and cook briefly until
fragrant.
Whisk in flour and cook for 1
minute.
Slowly pour in milk and cream while
whisking continuously.
Add Dijon mustard, thyme, salt, and
pepper.
Cook until the sauce thickens and
becomes smooth.
5.
Assemble the Gratin
Place broccoli evenly in the baking
dish.
Add seasoned salmon pieces on top.
Pour the creamy sauce over
everything evenly.
6.
Add the Topping
In a small bowl, mix mozzarella
cheese, Parmesan cheese, breadcrumbs, and melted butter.
Sprinkle evenly over the casserole.
7.
Bake Until Golden
Bake uncovered for about 20–25
minutes until bubbly and golden brown.
The salmon should be fully cooked
and flaky.
8.
Rest Before Serving
Allow the gratin to rest for 5
minutes before serving.
This helps the sauce set slightly.
9.
Garnish and Serve
Top with parsley, lemon wedges, or
chili flakes.
Serve warm.
