This Keto Salmon Quiche has a golden low-carb crust filled with tender baked salmon, eggs, cheese, and fresh herbs. It's a delicious way to use leftover salmon and makes a lovely lunch or dinner with a fresh salad on the side.
Prepare the crust. Preheat the oven to 350°F (175°C). Prepare the savory keto pie crust according to its recipe. Press the dough evenly into a greased pie pan, covering the bottom and sides. Prick the bottom with a fork, then bake for 10–12 minutes, until lightly golden. Remove from the oven and let cool slightly.
Cook the onion. Meanwhile, melt the butter in a small skillet over medium heat. Add the chopped yellow onion and cook for 3–4 minutes, until softened and translucent. Stir in the green onion and cook for another 30 seconds. Remove from the heat.
Prepare the egg mixture. In a large mixing bowl, whisk together the eggs, heavy cream, water, Parmesan, shredded cheese, salt, and black pepper until well combined.
Assemble the quiche. Spread the cooked onions evenly over the partially baked crust. Add the flaked salmon and sprinkle with fresh dill, distributing everything evenly.
Add the filling. Slowly pour the egg and cheese mixture over the salmon. Make sure the filling is evenly distributed without overflowing the crust.
Bake. Bake at 350°F (175°C) for 45–50 minutes, or until the edges are set and the center is no longer liquid. The filling should reach 160°F (71°C) in the center.
Let it rest. Remove the quiche from the oven and let it rest for 5–10 minutes before slicing. This helps the filling set and makes it easier to serve.
Serve. Cut into 8 slices and serve warm with fresh dill and a simple green salad.
