Oma's Easy Weekday Salmon Casserole (Überbackener Lacks mit Spinat)

My go-to German salmon casserole with spinach, potatoes, and cheese, baked till creamy ... mega lecker!

Ingredients:

• 1 lb (454 g) salmon fillets
• 2 tbsp (30 ml) lemon juice
• salt and freshly ground black pepper, to taste
• 1 onion, diced
• 1 tbsp (14 g) butter
• 2 garlic cloves, minced
• 1 tbsp (8 g) all-purpose flour
• 1 cup (240 ml) heavy (whipping) cream
• 1 cup (240 ml) milk, divided
• ⅓ lb (151 g) grated Emmental, divided
• freshly grated nutmeg, to taste
• 2 large eggs
• 1½ lb (681 g) potatoes, cooked and thickly sliced
• 1 lb (454 g) frozen spinach, thawed and well drained
• fresh dill, to garnish

Instructions:

1. Preheat the oven to 400°F (205°C). Grease a 9×13-inch casserole dish and set aside.
2. Cut the salmon into bite-sized pieces. Sprinkle the pieces with the lemon juice, salt, and pepper. Set aside.
3. In a frying pan, sauté the diced onion in the butter until they become translucent. Add the garlic. Stir in the flour and cook briefly.
4. Mix the cream and ¾ cup (180 milliliters) milk. Add the mixture to the frying pan and whisk until smooth.
5. Add half the cheese to the sauce. Season with salt, pepper, and a generous amount of nutmeg. Remove the saucepan from the heat.
6. Whisk the eggs with the remaining ¼ cup (60 milliliters) milk and stir the mixture into the sauce.
7. Place the potatoes in the casserole dish. Spoon a bit of the sauce over the potatoes. Cover with the spinach. Evenly spread the salmon pieces over top.
8. Spoon the remaining sauce over the top. Sprinkle with the remaining cheese.
9. Bake, uncovered, for about 35 minutes. The cheese and sauce should be bubbly and the salmon should flake when cut.
10. Serve, topped with fresh dill.

Notes/Hints:

• Use Gouda or Swiss cheese.
• If you make this ahead of time, put it in the fridge until it's time to bake. You will need to increase the baking time by about 10 minutes.
• Use a casserole dish that is large and shallow rather than narrow and deep. It will allow the potatoes and spinach to heat up quicker.
