Potato Crust Quiche – Easy Gluten-Free Quiche Recipe

This Potato Crust Quiche is a delicious alternative to traditional quiche made with pastry. Instead of a flour-based crust, grated potatoes form a crispy, golden crust that holds a creamy egg, cheese and bacon filling. It is naturally gluten-free and makes a satisfying breakfast, brunch, lunch or dinner.

I love how easy this quiche is to customize. You can keep the bacon and Gruyère for a rich, savory filling, or add vegetables such as broccoli, spinach, mushrooms or red peppers.

Ingredients for Potato Crust Quiche

For the potato crust

Potatoes: Red potatoes work well because they hold their shape and create a sturdy crust. Rinse the grated potatoes and squeeze out as much moisture as possible so the crust becomes crisp rather than soggy.

Olive oil: Helps the potato crust brown and become crisp around the edges.

Salt, pepper and garlic powder: Simple seasonings that add flavor to the potatoes.

For the quiche filling

Bacon: Cook it until crisp before adding it to the quiche for the best texture and flavor.

Eggs: Create the structure of the creamy quiche filling.

Cooking cream: Makes the filling rich and tender. Whole cream can also be used.

Gruyère or cheddar cheese: Both work well here. Gruyère gives the quiche a deeper, nutty flavor, while cheddar adds a familiar sharpness.

Green onions: Add a fresh, mild onion flavor that works especially well with the potatoes, bacon and cheese.

Nutmeg: Just a pinch adds a subtle warmth to the creamy egg filling.

How to make potato crust quiche

First, you have to prepare the potato crust. Grate the potatoes and rinse well under cold water. Use a kitchen towel to squeeze as much liquid as possible. Transfer the potatoes to a large bowl and mix with salt, pepper, garlic powder, and olive oil. 

Spread the potatoes over the base and sides of a greased pie pan and press slightly. Bake at 400F (200C) for 30 minutes until slightly golden. While the crust is baking, cook the bacon in a medium frying pan until crisp and drain on paper towels. Grate the cheese and set aside until ready to use. Reduce the oven temperature to 350F (180C).

Now you can prepare the filling by whisking together the eggs with cream, salt, pepper, nutmeg and chopped green onions. 

At this point, you can easily customize this potato crust quiche to suit different dietary needs and preferences. Besides being gluten-free, you can adapt it to make it vegetarian or vegan too, by using dairy-free cheese and leaving out the bacon. You can use various ingredients for the filling, like spinach, red pepper, or mushrooms, and add more nutrients to this potato dish. 

Fill the potato crust with grated cheese and crispy bacon.  Pour the egg mixture over the potato crust. Bake in the oven until the filling is set and the top is golden brown. 

Let the quiche cool slightly. Cut into wedges and serve hot or cold alongside a fresh salad and crusty bread.  

Whether you are looking for a hearty breakfast, a light lunch, or a savory dinner, this Potato Crust Quiche is sure to satisfy your cravings and impress your guests.

Tips for Making Potato Crust Quiche

• Squeeze the potatoes well. This is one of the most important steps. Excess moisture can prevent the potato crust from becoming crisp.
• Press the potatoes firmly into the pan. Cover the bottom and sides evenly so the crust holds together when sliced.
• Bake the crust before adding the filling. The potato crust needs a head start in the oven so it becomes golden and sturdy.
• Cook the bacon until crisp. This keeps it flavorful and prevents the filling from becoming too greasy.
• Let the quiche rest before slicing. Give it at least 10 minutes to cool so the filling can set properly.
• Don’t be afraid to change the filling. Broccoli, spinach, mushrooms, red peppers and other vegetables can be added along with the cheese.

Potato Crust Quiche Variations

You can easily adapt this quiche to what you have in the refrigerator.

Vegetarian potato quiche: Leave out the bacon and add sautéed mushrooms, spinach, broccoli or bell peppers.

Broccoli and cheddar quiche: Replace the bacon with cooked broccoli and use sharp cheddar for a simple vegetarian version.

Mushroom potato quiche: Sauté sliced mushrooms before adding them to the filling so they release excess moisture.

Different cheese: Try cheddar, Gruyère, Swiss cheese or a combination of cheeses.

Frequently Asked Questions

Can I use a different type of potato?

Yes. While red potatoes work particularly well, you can use other potatoes as long as you squeeze out as much moisture as possible after grating.

Can I make this potato quiche without bacon?

Absolutely. Simply leave out the bacon and add vegetables such as broccoli, spinach, mushrooms or peppers for a vegetarian version.

Can I use milk instead of cooking cream?

For the creamiest filling, cream or whole cream works best. You can use milk, but the filling will be lighter and less rich.

Can I make the potato crust ahead of time?

You can bake the potato crust ahead and let it cool before adding the filling. When ready, add the filling and continue with the recipe.

How should I store leftover potato crust quiche?

Store leftovers covered in the refrigerator for up to 3 days. Reheat individual slices in the oven or microwave, or enjoy them cold.
