Mexican Quiche with Oat and Almond Crust

We all have daily rituals, those things we do that keep us sane, grounded and less irritable to the world. My mornings begin with a cup of piping hot tea, two cups if things are looking a bit rough. You don’t want to talk to me before I’ve had my morning shot of caffeine. I’m incapable of forming actual sentences. Words, out they come, particular order, none.

Two things I’ve added to my daily routine lately: word games (specifically, Codewords) and quiche. Word games to flex the brain muscles, quiche to nourish them.

I got the idea for this quiche when I was flipping through the morning paper in England (tea in hand, of course). It was a vegan Mediterranean quiche made with tofu instead of eggs. The tofu filling seemed like a bold move, even for me. The experimentation will come an another time, for sure. Just not now.

This quiche looks all fancy, but it comes together easy peasy. Just mix the ingredients into a dough, press it into a tart (or pie pan), fill with the egg/veggie mix, bake, and, MAGIC. Fresh quiche, right at your fingertips.

This quiche also gets bonus recipe points because it stays good for a few days, so that we can all have quiche breakfasts with a cup of tea in the morning. Care to join?

  • Baking the Crust: Before baking the crust, make sure to press along the bottom crease of the pan. This ensures that you don’t get a thick piece of crust along the edges. You may notice that the pie crust puffs up in the center or forms a few small cracks after you par bake it. That’s fine. Just press it back down with the back of a spoon.
  • Using a Pie Dish: I haven’t tried this but you can probably bake this quiche in a regular 9-inch pie dish. You may have a bit too much filling, so watch out!
  • More Flavor Combinations: I tested a version of this quiche with a few tablespoons of diced green chiles and sliced green onion, and it tasted great!
  • Handling Tart Pans: Whenever you’re moving around a tart pan that’s filled, be sure to lift from the edges, and not the center. I made that mistake once and the filling of my tart spilled all over the floor. We ain’t got time for a messy kitchen here.
  • Chopped Cilantro: I’ve been using a lot of Gourmet Garden’s lightly dried herbs lately. They come in very handy because the herbs are all chopped up, and the herbs last about 4 weeks in your refrigerator even after the package is opened! Serious kitchen time saver. I used this lightly dried cilantro for the quiche.

  • 1 1/4 cups (135g) rolled oats
  • 1 cup + 3 TBS (150g) almond flour
  • 1 tsp dried oregano
  • 1/2 tsp ground cumin
  • 1/2 tsp sea salt
  • 1 large egg + 1 egg white
  • 1/2 to 1 tablespoon water
  • cooking spray
  • Filling
  • 1/2 TBS olive oil
  • 2/3 cup (80g) chopped red onion
  • 1 clove garlic, minced
  • 1/3 cup (20g) chopped red pepper
  • 1 small tomato (20g), seeded and diced
  • 1 tsp dried oregano
  • 1/2 tsp dried cumin
  • 4 large eggs + 1 egg yolk
  • 1/2 cup (120ml) low-fat milk (I used 2% milk)
  • 1/2 cup (55g) shredded pepper jack cheese
  • 1 tsp sea salt
  • freshly cracked pepper
  • 1/2 TBS chopped cilantro


  1. Spray a 10-inch tart pan with cooking spray. Set aside.
  2. Preheat oven to 350 degrees F (175 degrees C).
  3. Place rolled oats in a food processor and mix until it turns into flour. It's okay if the flour is still a little gritty. Pour in a large bowl. Mix in almond flour, oregano, cumin and salt. Whisk egg and egg white together, and mix with flours. A dough should start to form. Add water to the dough, about 1/2 tablespoon at a time. Use as much water as necessary to get a slightly moist dough. Place dough in tart pan, and using your fingers, press dough so that it covers every part of the pan. Be sure to press down along the bottom crease of the pan to prevent an overly thick crust. Bake for 15 minutes.
  4. While dough is baking, prepare filling. Heat oil in a skillet over medium-high heat. Cook onions until soft, about 2 to 3 minutes. Add pepper and cook for another minute. Turn off heat. Mix in diced tomatoes, 1 teaspoon oregano and 1/2 teaspoon cumin. Set aside.
  5. Whisk 4 eggs and remaining yolk in a medium bowl, Mix in milk, cheese, salt, and some pepper.
  6. Take crust out of the oven and raise the heat to 375 degrees F (190 degrees C). The crust may puff up a little, but just press it down with a spoon. Spoon half the vegetables on to baked crust. Mix rest of vegetables with egg mixture. Pour egg mixture into tart pan. Sprinkle cilantro on top.
  7. Bake quiche for 23 to 25 minutes, until the center of the quiche is firm to touch. The filling may puff up at different spots when it comes out the oven, but it will deflate once it cools.
  8. Slice and serve immediately.

    Theres nothing like a good Quiche! I find it's an anytime food; breakfast, lunch or dinner. Making it for dinner then having breakfast on the ready the next morning is the best! With tea of course! Love the Mexican flavors you've used here, Lisa... you've reminded me it's been way too long since I made quiche! Thank you my dear!

      That quiche has served me well the past few weeks! Whenever I craved something savory, I just pop a small slice into the microwave, and I'm a happy girl.

    would it be ok to use coconut flour instead of almond? I have that one,but not almond and really don't want to buy another one to have laying around.

      Hi Joan! I haven't used coconut flour for this recipe before, but I think it would work. However, I would alter the oats/flour ratio because coconut flour just doesn't have as much structure as almond flour. I would probably do something like 1 1/2 or 1 2/3 cups of oats to 3/4 cup + 2 TBS coconut flour. Hope this helps!
