Step 1: Preheat the Oven
Preheat your oven to 180°C (350°F). Lightly spray a 23 cm (9-inch) quiche dish with cooking spray.
Step 2: Prepare the Sweet Potato Crust
Place the raw sweet potato pieces and rolled oats in a food processor. Blend until finely chopped.
Add one egg, garlic powder, salt, and black pepper. Blend again until the mixture starts to hold together.
Step 3: Bake the Crust
Transfer the mixture into the prepared quiche dish. Press it firmly across the bottom and up the sides to create an even crust.
Bake for 20 minutes until slightly golden and firm.
Step 4: Make the Filling
In a large bowl, whisk the remaining five eggs.
Add the cooked shredded chicken, reduced-fat mozzarella, dried herbs, onion powder, salt, and pepper. Stir until everything is well combined.
Step 5: Assemble the Quiche
Remove the baked crust from the oven and carefully pour in the chicken and egg mixture.
Arrange the asparagus pieces evenly over the filling and sprinkle the grated Parmesan cheese on top.
Step 6: Bake Until Golden
Return the quiche to the oven and bake for 25–30 minutes, until the filling is completely set and the top is golden brown.
Allow it to cool for 5–10 minutes before slicing.
Serve warm or cold with a fresh green salad.
