What is zucchini quiche?
Quiche is a savoury French tart, usually made with an egg-and-cream custard baked in pastry. This version keeps the familiar creamy filling but uses an almond and coconut flour crust instead of conventional pastry.
Courgette, cheese and herbs give the filling its savoury character, while tomato and courgette slices make a colourful topping. The contrast between the tender filling and the sturdier nut-flour crust is what makes this version work.

The almond flour, butter, cheese and cream supply much of the fat, while the eggs and cheese contribute protein. The courgette and small amount of flour contribute most of the carbohydrate; pair a slice with salad or extra green vegetables for a more balanced plate.
The nut-flour crust
Flour balance: almond flour brings richness, while coconut flour absorbs moisture and helps the crust hold together. Blend the crust ingredients until evenly combined before pressing the mixture into the dish.
Chilling: give the shaped crust its full 30 minutes in the refrigerator. This helps it firm up before baking and makes it easier to handle.
Getting the courgette ready
Grated courgette: squeezing it thoroughly in a clean towel is important because excess water can loosen the custard and soften the crust. Take care when squeezing, as the courgette releases more liquid than it may first appear to hold.
Topping slices: cut the half courgette into thin, even slices so they sit neatly on the quiche and cook through in the final bake.
Blind-baking the crust
Baking weights: parchment and dry beans help stop the base from puffing up while it bakes. Spread the weights across the crust rather than piling them in one spot.
Colour cue: bake the crust for 15 minutes, checking for a lightly golden surface. It will bake again once filled, so it does not need to be deeply browned at this stage.
Checking when it is done
Filling: bake for 25–30 minutes, looking for a firm centre and a golden top. If the centre still looks loose, give it a little more time and check again.
Resting: let the quiche cool for a few minutes before cutting. This brief pause helps the slices hold their shape.
Serving ideas
Fresh side: serve a warm slice with a crisp green salad or simply dressed leaves to complement the rich filling.
For a fuller meal: add steamed green vegetables or a bowl of soup. The quiche can also be served at room temperature for a picnic-style lunch.
Recipe notes & tips
- Use a 23 cm pie dish so the crust and filling sit at the intended depth.
- Squeeze the grated courgette over the sink or a bowl to catch the released liquid.
- Keep the crust pressed to an even thickness across the base and sides.
- Let the crust cool briefly while you prepare the filling.
- Use a sharp knife to cut clean slices after the quiche has rested.
Variations
- Cheese swap: use either cheddar or Gouda as listed for a slightly different savoury flavour.
- Herb change: replace the dried rosemary with dried thyme for a different herbal note.
- Extra vegetables: add a small amount of finely chopped spring onion, as mentioned in the method, if you have it.
- Tomato topping: arrange the sliced cherry tomatoes evenly for a bright finish.
- Peppery finish: add a little more freshly cracked black pepper to the filling before baking.
Common mistakes to avoid
- Wet courgette: squeeze the grated courgette well so its liquid does not thin the filling.
- Skipping the chill: refrigerate the shaped crust for about 30 minutes so it firms before baking.
- Unweighted crust: use parchment and dry beans to help keep the crust base flat.
- Uneven crust: press the mixture to a similar thickness across the base and sides for more even baking.
- Cutting too soon: allow a few minutes of cooling so the filling has a chance to settle.
How to store
Refrigerate leftover quiche in a covered container for up to 3 days. Reheat slices in the oven until warmed through, or serve them cold or at room temperature.
Frequently asked questions
Can I make the quiche ahead?
Yes. Bake it in advance, let it cool, then cover and refrigerate. Reheat slices in the oven or serve the quiche cold.
How do I know the filling is cooked?
The filling should look firm rather than liquid in the centre, and the top should be golden. Bake for the stated 25–30 minutes, checking towards the end.
Why does the grated courgette need draining?
Courgette releases a lot of water as it cooks. Squeezing it out helps keep the egg filling from becoming watery.
Can I use cheddar instead of Gouda?
Yes. The ingredients list either grated cheddar or Gouda, so use whichever you prefer.
Why bake the crust before adding the filling?
The initial bake sets and colours the crust before it is filled. Parchment and dry beans help hold its shape during this stage.
Are spring onions included?
The method mentions chopped spring onions, but the ingredient list gives no quantity and does not list them. They are therefore not included in the ingredient quantities above.
