This potato crust quiche has transformed my breakfast routine with its perfect balance of crispy potatoes and protein-packed filling. It's become my go-to weekend brunch dish that impresses guests while being surprisingly simple to prepare.
I first created this recipe when hosting a brunch for friends with various dietary restrictions. The potato crust was my solution to accommodate everyone, and it ended up becoming more popular than traditional pastry crusts. Now it's requested at every gathering.
Key Ingredients
- Potatoes: Choose starchy varieties like russets for the crispiest crust results
- Olive oil: Helps bind the potato crust and creates that golden exterior
- Eggs: Provide structure and protein; the fresher the better for maximum flavor
- Almond milk: Creates a lighter texture than dairy milk and keeps the recipe dairy-free
- Onions: Offer an aromatic base that flavors the entire quiche
- Spinach: Packs in nutrients and wilts perfectly into the egg mixture
- Bell peppers: Add sweet crunch and vibrant color
- Grape tomatoes: Burst with juicy flavor when baked
- Mushrooms: Contribute earthy umami notes that balance the dish
- Salt and pepper: Enhance all the flavors without overpowering
- Garlic powder: Adds depth without the harshness of fresh garlic
Step By Step Instructions
- Prepare the Potato Crust:
- Grating fresh potatoes is the secret to this recipe. After grating, the critical step is removing excess moisture by squeezing thoroughly with a clean kitchen towel. This prevents a soggy crust and ensures maximum crispness. Toss with olive oil which helps conduct heat evenly for perfect browning.
- Form and Pre-bake the Crust:
- Press the grated potatoes firmly against the sides and bottom of your pie plate, creating an even layer about ¼-inch thick. The pre-baking step at high heat is essential for developing a sturdy crust that will hold up to the egg filling without becoming soggy.
- Prepare the Filling:
- Whisking eggs until slightly frothy creates a lighter texture in the finished quiche. Fold in your chopped vegetables gently to maintain their integrity and ensure even distribution throughout the quiche.
- Assemble and Bake:
- Pour the egg mixture slowly into the pre-baked crust to prevent disrupting the delicate potato edges. The lower temperature for the second bake allows the eggs to set gently without becoming rubbery.
- Rest Before Serving:
- The ten-minute rest period is not optional. This allows the proteins in the eggs to relax and firm up, making slicing clean and presentation-worthy.

I discovered the potato crust technique after experimenting with hashbrown breakfast casseroles. The moment I tasted how the edges of the potatoes caramelized against the glass pie plate, creating a savory contrast to the fluffy eggs, I knew I'd found something special. My family now judges all quiches against this version.
Make-Ahead Options
This quiche can be fully prepared up to three days in advance. Store it covered in the refrigerator and reheat individual slices in a 350°F oven for about 10 minutes until warmed through. The potato crust maintains its texture surprisingly well, unlike pastry crusts that often become soggy when stored. For longer storage, freeze individual slices wrapped tightly in plastic wrap and foil. Thaw overnight in the refrigerator before reheating for best results.
Vegetable Variations
The beauty of this recipe lies in its adaptability to whatever produce you have available. In summer, I love using fresh zucchini, corn, and basil. Fall calls for butternut squash, sage, and caramelized onions. Winter versions might include roasted brussels sprouts and leeks. Just maintain the same total volume of vegetables to ensure proper cooking. Always pre-cook watery vegetables like zucchini or mushrooms to remove excess moisture before adding to the egg mixture.
Making It Your Own
While this version remains paleo and Whole30 friendly, the recipe welcomes modifications. Adding cheese transforms the dish entirely—try sharp cheddar for classic flavor or goat cheese for tangy complexity. Dairy milk substitutes beautifully for almond milk. For meat lovers, cooked bacon, sausage, or ham fold in perfectly with the vegetables. Just remember that any additions should be fully cooked before adding to the egg mixture.
Serving Suggestions
For an impressive brunch spread, pair this quiche with a simple arugula salad dressed with lemon and olive oil. The peppery greens complement the richness of the eggs. A side of fresh fruit provides sweet balance. If serving for dinner, roasted vegetables or a hearty soup make excellent companions. The quiche tastes wonderful at room temperature, making it perfect for picnics or buffet-style gatherings.
