Savory Onion Pie: A Comfort Food Classic

The first time I tasted onion pie was at my grandmother’s farmhouse. I remember the aroma of sweet, caramelized onions mingling with the buttery scent of the crust filling the entire kitchen. It was a cold autumn evening, and the warmth of the pie, both in temperature and flavor, was exactly what my soul needed. The savory, slightly sweet taste has been a cherished memory ever since, a testament to simple ingredients transformed into something truly special.

• 1 ½ cups sharp cheddar cheese, shredded
• 2 teaspoons mustard
• 1 teaspoon salt
• 1 teaspoon ground black pepper
• ⅛ cup all-purpose flour

Instructions

1. Prepare the pie crust: This step is best done a day in advance to allow the dough to chill properly. In a large bowl, combine the flour and salt.

2. Cut in the shortening: Using a pastry blender or your fingertips, cut the shortening into the flour mixture until it resembles coarse crumbs. The smaller the pieces of shortening, the flakier the crust will be.

3. Add the water: Slowly stir in the water, a little at a time, until the mixture forms a ball. Be careful not to overwork the dough, as this can result in a tough crust. Use only as much water as you need to bring the dough together.

4. Chill the dough: Wrap the dough in plastic wrap and refrigerate overnight, or for at least 4-5 hours. This chilling period is crucial for allowing the gluten to relax and the shortening to solidify, which will contribute to a tender and flaky crust. The original recipe recommends overnight chilling for best results.

5. Roll out the first crust: On a lightly floured surface, roll out one of the balls of dough into a circle large enough to fit your 9-inch pie pan. Gently transfer the dough to the pie pan and crimp the edges. Refrigerate the prepared bottom crust while you prepare the filling.

6. Sauté the onions: In a large skillet, melt the butter over medium heat. Add the thinly sliced yellow onions, salt, and pepper. Sauté the onions until they are tender and translucent, but not browned. This process can take about 15-20 minutes. Stir frequently to prevent sticking and ensure even cooking. At the end of the cooking time, add the minced garlic and sauté for another minute, until fragrant.

7. Assemble the filling: Spread the sautéed onions evenly over the bottom layer of pastry. Sprinkle the shredded cheddar cheese over the onions.

8. Prepare the egg mixture: In a separate bowl, whisk together the slightly beaten eggs, mustard, salt, pepper, flour, cream of mushroom soup, and milk. Blend until smooth and well combined.

9. Pour the filling: Pour the egg mixture evenly over the onions and cheese in the pie pan.

10. Roll out the top crust: Roll out the second ball of dough into a circle large enough to cover the pie. Carefully lay it over the filling.

11. Seal and vent the crust: Cut slits in the top crust to allow steam to escape during baking. This will prevent the crust from becoming soggy. Secure the top crust to the bottom crust by pinching the edges together or pressing them together with the tines of a fork.

12. Bake the pie: Bake the pie in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) for 45-60 minutes, or until the crust is golden brown and the filling is set. A knife inserted into the center should come out clean. If the crust starts to brown too quickly, you can cover it loosely with foil.

13. Cool and serve: Let cool for at least 20 minutes before slicing and serving. This will allow the filling to set up a bit more, making it easier to slice.

Expert Tips & Tricks

• Caramelizing the Onions: For a sweeter, deeper flavor, caramelize the onions instead of just sautéing them. This will require a longer cooking time and more patience, but the result is worth it. Cook the onions over low heat for 30-45 minutes, stirring frequently, until they are a rich golden brown.
• Pre-Baking the Crust: To prevent a soggy bottom crust, you can pre-bake it for 10-15 minutes before adding the filling. This will help to crisp it up and create a barrier against the moisture from the filling.
• Cheese Variations: Feel free to experiment with different types of cheese. Gruyere, Swiss, or a blend of cheeses would all work well in this pie.
• Make-Ahead Tip: The filling can be prepared a day in advance and stored in the refrigerator. This will save you time on the day you want to bake the pie.

Serving & Storage Suggestions

This savory onion pie is delicious served warm or at room temperature. It makes a great appetizer, side dish, or even a light meal. It pairs well with a simple green salad or a cup of soup.

Storage: Leftover pie can be stored in the refrigerator for up to 3-4 days. To reheat, warm in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) for about 15-20 minutes, or until heated through. You can also reheat individual slices in the microwave. The pie can also be frozen for longer storage. Wrap it tightly in plastic wrap and then in foil. It will keep in the freezer for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
