  • Total Time: 1 hour

Ingredients

Units Scale

Gluten-Free Crust

  • 1 cup gluten-free rolled oats
  • 1/2 cup nut flour (or ground nuts or seeds)
  • 1/2 cup rice flour
  • 1/2 cup flax seeds
  • 2 tbsp tapioca or potato starch
  • 1/2 tsp sea salt
  • 3/4 cup coconut oil

Filling

  • 1 red onion
  • 2 cloves garlic
  • handful of basil and mint leaves
  • handful of green peas
  • 1 cup asparagus
  • 1/2 small head cauliflower
  • 3 eggs
  • 1 tsp sea salt

Instructions

  1. Start with the crust. In a blender or coffee grinder, grind rolled oats into coarse crumbs. Mix all dry ingredients, including nut flour, rice flour, flax seeds, tapioca starch and sea salt. Add 3/4 cup of room temperature coconut oil. Form a dough ball with your hands and place it in the refrigerator for 5-10 minutes, but no more.
  2. Meanwhile, prepare the filling. Separate half of a small cauliflower head into florets, blanch them for 3 minutes in boiling water, then let them cool. Blend the cooled cauliflower in a blender with 3 eggs and 1/2 teaspoon of salt.
  3. Spread the bottom and sides of a baking dish with oil and cover evenly with the gluten-free base layer (about 5mm thick). Bake in a preheated oven at 350°F (180°C) for 15 minutes, or until the edges are lightly golden.
  4. While the base is baking, prepare the rest of the filling for the quiche. Finely chop 1 red onion of a medium size and thinly slice 2 cloves of garlic. Heat a heavy-bottomed skillet. Melt 1-2 tbsp coconut oil (or ghee) and sauté the garlic and onion until slightly caramelized.
  5. Blanch a handful of green peas and 1 cup of asparagus separately for 30 seconds, adding 1/2 tsp salt.
  6. Remove half-cooked crust from the oven. Spread caramelized onion and garlic on the bottom, add blanched peas, and pour 1/2 of the egg and cauliflower mixture. Arrange a layer of asparagus spears on top and pour the remaining mixture. Place another layer of asparagus on top. Sprinkle with freshly ground pepper and bake for 25 minutes at 350°F (180°C).
  7. When ready let the quiche cool slightly. Before serving, garnish with chopped basil and mint leaves.
