"You can substitute any shredded cheese to your liking. For a heartier quiche, substitute one cup of the zucchini for one cup of shredded potato (squeeze out excess water.)"

Why it works: Cheddar cheese and parmesan cheese match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 592 recipes mention both. Both carry ethyl 2-methylbutyrate, which smells fruity, apple. The science ↓

Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Preheat the oven to 350°F (175°C). Grease a 9-inch pie plate with cooking spray, then dust it with the dry bread crumbs, tapping out any extra.

  2. Squeeze excess liquid from the shredded zucchini using a clean towel or by pressing it in a sieve.

  3. In a large bowl, whisk the well-beaten eggs with the vegetable oil until combined.

  4. Stir in the biscuit baking mix, minced onion, minced garlic, dried oregano, salt, and black pepper until smooth.

  5. Fold in the zucchini, shredded Cheddar, and chopped parsley until evenly distributed, then pour the mixture into the prepared pie plate.

  6. Sprinkle the grated Parmesan evenly over the top.

  7. Bake for 40 to 45 minutes, until the top is golden and a knife inserted in the center comes out clean. The eggs must be fully set.

  8. Let the quiche cool for 10 minutes on a rack before slicing and serving.

Flavor stand-ins for the parsley

How well each one fits the dish's main ingredients (bread, egg, biscuit, onion, cheddar cheese, parmesan cheese, garlic):

  1. Pepperabout as good a flavor fit
  2. Celeryabout as good a flavor fit
  3. Parsleythe original
  4. Capersabout as good a flavor fit

Fit is the average pairing score against bread, egg, biscuit, onion, cheddar cheese, parmesan cheese, garlic. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
