Step 1: Preheat your oven to 375 degrees F.

Step 7: Pour the mixture into the prepared baked pie crust.
Step 8: Top with sliced green onions.

Step 9: Bake for 40-50 minutes until set. The top will look a little soft, but it will reach 160 degrees F on an instant read thermometer.
Step 10: Let cool for 5-10 minutes before slicing and serving.

Instructions
- Preheat and blind bake. Preheat the oven to 375°F. Prick the pie crust several times with a fork and blind bake for 10 minutes. Remove from the oven and set aside.

- Whisk the eggs. In a large bowl, whisk the eggs until fully beaten. Add the milk and whisk again until combined.
- Build the filling. Stir the onion and garlic mixture into the eggs. Add the spinach, chopped salmon, Swiss cheese, salt, and pepper, stirring gently to combine.
- Assemble the quiche. Pour the egg mixture into the prepared pie crust and sprinkle the green onions evenly over the top.
- Bake. Bake for 40 to 50 minutes, until the center is set and the quiche reaches 160°F on an instant-read thermometer.

Notes

- Salmon options. Smoked salmon can be replaced with canned boneless salmon, drained, or 1 cup of cooked leftover salmon.
