Spinach Caramelized Onion and Feta Quiche: Step-by-Step Guide

Step 1: Prepare the Onions

In a skillet over medium heat, add 2 teaspoons of olive oil. Once heated, add 3 cups of chopped onions and sauté until they begin to soften. Sprinkle in 1 teaspoon of granulated white sugar to help with the caramelization process. Stir frequently, allowing the onions to turn a rich golden brown, about 15-20 minutes. Once done, set them aside to cool slightly.

Step 2: Prepare the Hash Brown Crust

Preheat your oven to 375°F (190°C). In a mixing bowl, combine the 2 cups of thawed Southern-style hash brown potatoes with a pinch of salt. Press the mixture into the bottom and up the sides of a greased 9-inch pie dish to form a crust. Bake in the preheated oven for about 20 minutes or until golden brown. Remove from the oven and let it cool slightly.

Step 3: Combine the Filling Ingredients

In a large mixing bowl, whisk together 1 cup of nonfat milk, 3 large egg whites, and 2 large eggs until well combined. Fold in the thawed, drained, and squeezed dry 10-ounce package of frozen chopped spinach, the caramelized onions, and 1 1/2 cups of crumbled feta cheese. Mix until everything is evenly distributed.

Step 4: Assemble the Quiche

Pour the filling mixture over the baked hash brown crust, ensuring it’s evenly spread out. The filling should sit just below the edge of the crust.

Step 5: Bake the Quiche

Place the assembled quiche back in the oven and bake for 30-35 minutes, or until the filling is set and lightly golden on top. You can check for doneness by inserting a knife into the center; it should come out clean.

Step 6: Cool and Serve

Once baked, remove the quiche from the oven and allow it to cool for at least 10 minutes before slicing. This resting period helps the filling set further, making it easier to cut clean slices. Serve warm or at room temperature.

Variations for Dietary Needs

• Dairy-Free: Substitute nonfat milk with a plant-based milk like almond or soy, and replace feta with a dairy-free cheese alternative.
• Gluten-Free: Use a gluten-free pie crust instead of the breadstick dough.
• Vegetarian: This recipe is already vegetarian-friendly, but feel free to add other vegetables like bell peppers or mushrooms for added flavor.
• Protein Boost: For added protein, mix in cooked and crumbled turkey sausage or diced chicken.

Troubleshooting Tips

• If your quiche is too watery, ensure the spinach is thoroughly drained and squeezed dry before adding it to the filling.
• To prevent a soggy crust, bake the hash brown crust until it’s well browned before adding the filling.
• If the quiche is browning too quickly, cover it loosely with aluminum foil during the last 10 minutes of baking.
• For a firmer filling, you can add an extra egg or reduce the amount of milk slightly.

Storage Pro Tips

Leftover Spinach Caramelized Onion and Feta Quiche can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply place slices in the microwave for about 30-60 seconds or warm in the oven at 350°F (175°C) until heated through.

• Freezing: You can freeze slices of quiche for up to 2 months. Wrap each slice tightly in plastic wrap and place them in a freezer-safe bag.
• Thawing: To enjoy frozen quiche, thaw in the refrigerator overnight and reheat as desired.

Common Questions

Can I use fresh spinach instead of frozen?

How do I know when the quiche is done baking?

The quiche is done when the filling is set and the top is slightly golden. A knife inserted into the center should come out clean.

What can I serve with this quiche?

This quiche pairs wonderfully with a light green salad, fresh fruit, or some crusty bread for a complete meal.
