How to Make Sweet Onion Pie
1. Prepare the Crust
Preheat your oven to 375°F (190°C). Fit the pie crust into a 9-inch pie plate. Prick the bottom lightly with a fork and pre-bake (blind bake) for about 10 minutes to prevent sogginess. Remove and set aside.
2. Cook the Onions
In a large skillet over medium heat, melt butter with olive oil. Add the sliced sweet onions and cook slowly for 15–20 minutes, stirring occasionally.
You’re looking for soft, translucent onions with slight golden edges — not deeply browned. Season lightly with salt and pepper. Let cool slightly.
3. Prepare the Filling
In a mixing bowl, whisk together eggs and cream until smooth. Stir in shredded cheese, thyme, and parsley if using.
4. Assemble the Pie
Spread the cooked onions evenly into the pre-baked crust. Pour the egg and cheese mixture over the onions, ensuring everything is evenly distributed.
5. Bake
Place the pie in the oven and bake for 30–40 minutes, or until the center is set and the top is lightly golden. A knife inserted near the center should come out mostly clean.
6. Rest Before Serving
Allow the pie to cool for at least 10–15 minutes before slicing. This helps the custard set and makes cleaner slices.

Tips for Success

-
Stir in sautéed spinach or mushrooms.
