👩‍🍳 How to Make Sourdough Quiche

1. Make the Sourdough Crust:

1. In a bowl, mix flour and salt. Add cold cubed butter and cut it in using a pastry cutter or your fingers until the mixture resembles coarse crumbs.

2. Add the sourdough starter and mix until the dough just comes together. Add cold water if needed, 1 tbsp at a time.

3. Shape into a disk, wrap in plastic wrap, and refrigerate for at least 1 hour.

2. Blind Bake the Crust:

1. Preheat oven to 375°F (190°C).

2. Roll out the chilled dough and fit it into a 9-inch tart or pie pan.

3. Prick the bottom with a fork, line with parchment paper, and fill with pie weights or dried beans.

4. Bake for 15 minutes, remove weights and parchment, then bake another 5–7 minutes until lightly golden.

5. Let the crust cool slightly while you prepare the filling.

3. Prepare the Filling:

1. In a mixing bowl, whisk together eggs, milk, cream, salt, and pepper.

2. Stir in shredded cheese, cooked bacon or veggies, and herbs if using.

4. Assemble and Bake:

1. Pour the filling into the pre-baked crust.

2. Bake at 375°F (190°C) for 35–40 minutes, or until the center is set and the top is golden.

3. Let cool for at least 10 minutes before slicing.

📝 Notes

• Sourdough Starter: This recipe works with discard or active starter. Discard will give a stronger tang.

• Make Ahead: The crust can be made and chilled up to 2 days in advance.

• Fillings: Try combinations like spinach + feta, mushroom + Swiss, or tomato + basil + mozzarella.

• Dairy-Free Option: Use unsweetened almond milk and dairy-free cheese, though the texture may vary.

❓ FAQs

Can I freeze sourdough quiche?

Yes! You can freeze the whole quiche or individual slices. Wrap tightly and freeze for up to 2 months. Reheat at 350°F (175°C) until warmed through.

Do I have to blind bake the crust?

Blind baking ensures the crust stays crisp and doesn’t get soggy from the filling. It’s highly recommended.

Can I use gluten-free flour for the crust?

Yes, you can use a 1:1 gluten-free flour blend, but the texture may be more crumbly.

What if I don’t have sourdough starter?

You can substitute with ¼ cup plain yogurt and ¼ cup flour to mimic the acidity and structure, but the flavor will differ.
