Fish Pie is a classic English dish, probably one of those originally invented to use up fish that was less than fresh. Slathered in mashed potatoes, cheese, and a creamy white sauce, the idea was to cover up the fish, not make it the main focus.
This recipe for Primal fish pie takes a completely different approach. The dish is still covered in a buttery mashed potato crust, but underneath is a light and flavorful filling. Fresh salmon and cod are layered with leeks, zucchini and fresh herbs, and flavored with lemon and Dijon.
The potatoes are flavored with nothing more than creamy, salty, delicious butter. Just keep adding it until the potatoes taste like, well, butter. If you can, use salted grass-fed butter, which has incredible flavor plus a healthier fatty acid composition and higher vitamin content than regular butter.
Servings: 4 to 6
Time in the Kitchen: 1.5 hour
Preheat oven to 400 Fº/205 Cº.
Cover potatoes with salted water in a pot and boil until soft, 12 to 15 minutes. Drain. Mash the drained potatoes with 4 tablespoons butter, or more if you like. Season with salt if needed. Set aside.
In a large saucepan, melt remaining 2 tablespoons/30 g butter over medium heat. Add the leek and celery. Cook until soft, 5 minutes. Add zucchini and cook until the zucchini is soft, 5 minutes.
In a 2 or 3 quart baking dish (or deep pie plate) layer vegetables and fish, and sprinkle lemon zest and parsley on top. Season lightly with salt and pepper.
In a small bowl, whisk together lemon juice, olive oil and Dijon mustard. Pour on top of the fish.
Smooth the mashed potatoes on top of the fish. Dot with small pieces of butter.
Bake for 40 minutes, or until lightly golden and crispy around the edges.
Fish pie can be served warm or at room temperature.
