Notes & Wine Advice
Serving Suggestions
Serve the quiche warm or at room temperature with a green salad, sliced tomatoes, roasted potatoes, or fresh fruit. It is also suitable for brunch and picnics. For a larger vegetarian meal, pair it with our Cheddar Zucchini Egg Casserole.Recipe Notes
Slice the zucchini thinly and evenly so it becomes tender during baking. Biscuit baking mix contains flour, fat, salt, and leavening, so regular flour cannot replace it without additional adjustments. The quiche is ready when the centre feels firm and no liquid egg remains.Variations
Replace cheddar with Monterey Jack, mozzarella, Gouda, or Parmesan. Add cooked mushrooms, spinach, roasted peppers, sweetcorn, chopped chives, or red pepper flakes. Drain vegetables containing considerable moisture before adding them.Storage
Refrigerate leftovers in an airtight container for up to three days. Reheat individual portions gently in the oven, air fryer, or microwave. The quiche can also be served chilled or allowed to return to room temperature before serving.Wine Advice
A crisp Sauvignon Blanc balances the richness of the eggs and cheddar. A fresh Pinot Grigio is another suitable choice for the mild zucchini and oregano.Nutrition values

About Crustless Zucchini Cheddar Quiche
Crustless Zucchini Cheddar Quiche is an uncomplicated vegetarian dish made with fresh zucchini, eggs, cheddar, onion, garlic, oregano, and biscuit baking mix. This easy zucchini quiche does not require a separate pastry crust. The baking mix gives the filling enough structure to produce neat, satisfying portions while keeping preparation short.
The recipe works well for brunch, lunch, a light family dinner, or a picnic. It can be served warm from the oven, chilled, or at room temperature. That flexibility also makes it useful for meal preparation and entertaining.
Preparing Crustless Zucchini Cheddar Quiche
Cut the zucchini into thin, evenly sized slices before mixing the filling. Thick pieces may remain too firm, while irregular slices can cook unevenly. There is no need to precook the zucchini, but pat it dry when its surface is especially moist.
Zucchini contains a large amount of water. Very large or mature zucchini may have a particularly watery centre, so remove the soft seeds before slicing. This helps the egg filling set properly and prevents excess liquid from collecting in the baking dish.
Grease the dish thoroughly, paying particular attention to the corners and sides. Because this quiche has no pastry crust, the egg and cheese mixture comes into direct contact with the baking dish.
Mixing the Easy Zucchini Quiche
Lightly beat the eggs before adding the biscuit baking mix. Whisk until no visible pockets of dry mix remain. Biscuit baking mix already contains flour, shortening, salt, and leavening, which helps the filling become lightly firm and golden during baking.
Do not replace the baking mix with an equal amount of ordinary flour. Plain flour does not contain the fat and leavening needed to produce the same texture. A homemade biscuit mix can be used when its composition is similar to the packaged version.
Add the onion, cheddar, garlic, oregano, salt, and black pepper before folding in the zucchini. Mixing the seasonings into the egg base first helps distribute them evenly. Fold the zucchini gently so the slices remain intact and become completely coated.
Baking and Checking the Centre
Spread the mixture evenly in the prepared baking dish. Zucchini slices piled in one section can produce uneven cooking and a watery centre. Bake uncovered until the surface is golden and the middle feels firm.
Insert a clean knife into the centre when you are uncertain whether the eggs are set. It should come out without liquid filling. A little melted cheese or moisture from the zucchini is normal, but uncooked egg means the quiche needs several additional minutes.
Allow the finished quiche to rest for 10 minutes. Resting gives the egg filling time to settle and makes cutting cleaner. It also allows moisture from the hot zucchini to redistribute instead of escaping immediately onto the plate.
Serving Ideas and Variations
Serve the quiche with a green salad, sliced tomatoes, roasted potatoes, or fresh fruit. For a larger vegetarian table, combine it with our Cheddar Zucchini Egg Casserole.
Mushrooms, spinach, roasted peppers, sweetcorn, or fresh herbs can be added in moderate quantities. Cook and drain moist vegetables before using them. Monterey Jack, mozzarella, Gouda, or Parmesan can replace some or all of the cheddar.
Storage and Food Safety
Cool leftovers promptly before placing them in an airtight container. Refrigerate for up to three days and reheat only the amount required. Individual portions can be warmed in the oven, air fryer, or microwave until hot throughout.
Keep the quiche properly chilled when transporting it to a picnic. Follow current FDA safe food-handling guidance when preparing eggs and dairy products and when cooling, transporting, storing, or reheating cooked dishes.
With tender zucchini, savoury cheddar, and straightforward preparation, Crustless Zucchini Cheddar Quiche is a versatile recipe for almost any meal.
