Dietary Variations:

  • To make this dish without potatoes, you could just leave them out and make it into a frittata. In that case you can just bake it directly in a lightly oiled pie pan or casserole dish.
  • To make this quiche dairy-free, use a dairy-free cheese. My favorite is storebought kite hill ricotta, or my homemade cashew ricotta.

This quiche takes about 45 minutes of prep and 45 minutes to cook. Great for a Sunday brunch or special occasion!

Potato Crust

  • 12 oz potatoes and/or sweet potatoes, sliced into thin rounds
  • 1 tsp olive oil
  • dash sea salt and pepper

Quiche Filling

  • 5 eggs, beaten
  • 1/2 cup milk of choice, I use non-dairy milk
  • dash of sea salt, black pepper, and nutmeg

Ideas for Add-Ins

  • sliced veggie sausage, browned first in a skillet
  • crumbled tempeh, browned first in a skillet
  • crumbled cheese, I use plant-based cheese
  • asparagus spears, trimmed and cut into 1/2" pieces
  • cherry tomatoes, halved
  • sliced mushrooms, browned first in a skillet
  • broccoli florets
  • diced bell peppers
  • spinach, kale, or chard, steam or sauté prior to adding
  • a dollop of pesto, swirled into the quiche mixture

Suggestions for Garnish

  • fresh chives or chive flowers
  • fresh basil, small leaves
  • green onions, sliced


  • Preheat the oven to 400° F.
  • Use a mandoline or sharp knife to thinly slice the potatoes into rounds.
  • In a lightly oiled pie pan or casserole dish, lay the potatoes in a single layer to cover the bottom and sides of the dish. It’s fine for them to overlap but don’t pile them on top of each other too much.
  • Spray lightly with oil (if desired) and sprinkle with salt and pepper.
  • Bake in the oven for 15 minutes, until partially cooked.
  • Beat the eggs with the milk in a bowl or pyrex liquid measuring cup. Stir in a dash of salt, pepper, and nutmeg.
  • Remove the potato crust from the oven. It should be partially cooked and starting to lightly brown.
  • Reduce the oven temperature to 375°.
  • Pour the egg mixture into the crust. Sprinkle in the add-ins such as veggies, protein, pesto, and cheese, distributing evenly. Don't overdo it on add-ins or the quiche will overflow.
  • Sprinkle salt and pepper over the top and return to the oven.
  • Bake for 40 to 45 minutes, or until the center of the quiche is set. Let rest for at least 15 minutes before eating.
  • Garnish with fresh herbs, if desired.
