Prepare the pie crust ahead of time, allowing it to chill for at least 2 hours before rolling out and blind baking.
Roll out the dough on a floured surface to a 12-inch diameter and place it in a 9-inch pie dish. Chill the crust for at least 30 minutes.
Preheat the oven to 400°F. Line the chilled crust with parchment paper, fill with pie weights, and bake until the edges start to brown, about 15-16 minutes.
Remove the weights, prick the crust with a fork, and bake for another 7-8 minutes until the bottom begins to brown.
Reduce the oven temperature to 350°F.
In a skillet, heat olive oil and garlic, add spinach, and cook until wilted. Set aside.
Whisk together eggs and milk, then add sun-dried tomatoes, goat cheese, spinach, salt, and pepper. Pour into the pre-baked crust.
Bake for 45-60 minutes until the center is set. Allow to cool for 15 minutes before serving.
