- After testing this recipe five times, I finally got it just right — the texture is creamy, not watery, and it holds together perfectly for slicing.
Ingredients You’ll Need
- 2 tablespoons olive oil
- 1 medium onion, finely diced
- 2 cloves garlic, minced
- 200g fresh spinach leaves
- 6 large eggs
- 200ml double cream
- 100ml whole milk
- 150g feta cheese, crumbled
- 50g grated Parmesan cheese
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon ground nutmeg
- Butter for greasing the dish
Tip: Use full-fat dairy here — it gives the quiche a silky, rich texture that lower-fat versions simply cannot match.
How to Make Crustless Spinach and Feta Quiche
- Preheat your oven to 180°C (160°C fan) and generously butter a 20cm round pie dish or a 20cm square baking dish. The butter helps release the quiche cleanly and adds a lovely golden edge.
- Heat the olive oil in a large frying pan over medium heat. Add the diced onion and cook for 4–5 minutes, stirring occasionally, until the pieces turn translucent and glossy and release a sweet, savoury aroma.
- Stir in the minced garlic and cook for 30 seconds until fragrant — you’ll smell it immediately, so don’t walk away. Add the spinach in handfuls, letting each batch wilt down before adding more. The leaves will turn a deep, vivid green and reduce dramatically in volume. This takes about 2–3 minutes total.
- Transfer the cooked spinach mixture to a clean tea towel or a fine-mesh sieve. Press gently with the back of a spoon to extract as much liquid as possible. This step is crucial — excess moisture will make your quiche watery and prevent it from setting properly.
- In a large mixing bowl, whisk the eggs until they are frothy and pale yellow, about 30 seconds of vigorous whisking. Add the double cream, milk, salt, pepper, and nutmeg, and whisk again until the mixture is completely smooth and uniform in colour.
- Fold the squeezed spinach mixture, crumbled feta, and grated Parmesan into the egg base. Stir gently until everything is evenly distributed — you should see flecks of green and white throughout the pale yellow custard.
- Pour the mixture into the prepared dish and spread it evenly with a spatula. Bake for 28–32 minutes, until the top is golden brown and the centre feels just set when you gently shake the dish — it should wobble slightly but not slosh. A knife inserted into the centre should come out clean.
- Let the quiche rest in the dish for at least 10 minutes before slicing. During this time, the residual heat finishes cooking the centre and the structure firms up, making slices clean and neat rather than messy.
Tips From My Kitchen
- Squeeze the spinach thoroughly: Fresh spinach holds a surprising amount of water. If you skip this step, your quiche will release liquid as it bakes and end up with a soggy texture. I use a clean tea towel and really wring it out — the more liquid you remove, the creamier the final result.
- Whisk the eggs until frothy: This incorporates air, which gives the quiche a lighter, more delicate crumb. Just 30 seconds of brisk whisking makes a noticeable difference in the finished texture.
- Let the onion cool slightly before adding the eggs: If you add hot onions directly to the egg mixture, you risk cooking the eggs prematurely and creating lumps. A 2-minute rest on the side is all it needs.
- Use a metal or ceramic dish for even baking: Glass dishes can cause uneven cooking, with the edges setting too quickly while the centre remains runny. A metal or ceramic dish distributes heat more consistently.
- Make it ahead for busy mornings: This quiche can be fully baked the night before, cooled, covered, and refrigerated. In the morning, slice it cold or reheat individual portions in the microwave for 45 seconds — perfect for grab-and-go breakfasts or packed lunches.
Equipment You’ll Need
- Large frying pan or skillet
- Sharp knife and cutting board
- Mixing bowls
- Wooden spoon or spatula
- 20cm round or square baking dish
- Whisk
- Clean tea towel or fine-mesh sieve
Common Mistakes to Avoid
- Overcrowding the pan: When wilting spinach, add it in batches rather than piling it all in at once. Too much spinach at once traps steam and leads to uneven wilting, with some leaves overcooked and others still raw. A handful at a time gives you control and consistent results.
- Wrong temperature: Baking at too high a temperature will cause the eggs to curdle and the top to brown before the centre sets. Stick to 180°C (160°C fan) and resist the urge to crank it up for speed — patience pays off here.
- Skipping the rest time: I know it’s tempting to slice straight from the oven, but the quiche needs that 10-minute rest to finish setting. Cutting too early releases steam and causes the structure to collapse, leaving you with a sloppy slice instead of a neat wedge.
Delicious Variations to Try
- Spicy Version: Add ½ teaspoon of red chilli flakes along with the garlic, and swap half the feta for a crumbled spicy cheese like pepper jack. The heat cuts through the richness beautifully.
- Vegetarian/Vegan Option: Replace the eggs with 400g of silken tofu blended until smooth, use plant-based cream and milk, and swap the cheeses for a vegan feta-style block. The texture will be slightly softer but still sliceable, and the flavour holds up well.
- Different Protein: Stir in 150g of shredded cooked chicken or diced turkey breast along with the spinach. This turns the quiche into a heartier meal that satisfies bigger appetites without extra effort.
What to Serve With Crustless Spinach and Feta Quiche
- A simple green salad dressed with lemon juice and olive oil — the acidity balances the creamy quiche.
- Roasted cherry tomatoes on the vine, drizzled with balsamic vinegar, for a burst of sweetness.
- Steamed green beans or asparagus, tossed in butter and flaked sea salt.
- For a more substantial meal, try it alongside my 30 Minute Greek Turkey Burgers With Cucumber Salad — the flavours complement each other perfectly.

Frequently Asked Questions
Can I use frozen spinach instead of fresh?
Yes, but you must thaw it completely and squeeze out every drop of water first. Frozen spinach contains even more moisture than fresh, so take extra care when pressing it dry. Use about 300g of thawed, squeezed frozen spinach to match the quantity of fresh.
Can I make this quiche dairy-free?
Absolutely. Substitute the double cream and milk with full-fat coconut milk or unsweetened almond milk, and use a dairy-free feta alternative. The texture will be slightly less firm but still delicious, and the coconut milk adds a subtle sweetness that works well with the spinach.
How do I store leftovers and reheat them?
Store cooled slices in an airtight container in the fridge for up to three days. To reheat, place a slice on a microwave-safe plate and heat on medium power for 45–60 seconds, or warm it in a 160°C oven for 8–10 minutes if you prefer a crisper edge.
Can I freeze this crustless quiche?
Yes, it freezes well. Let the baked quiche cool completely, then wrap it tightly in cling film and a layer of foil. Freeze for up to two months. Thaw overnight in the fridge and reheat as above — the texture remains creamy and intact.
Why is my quiche watery on the bottom?
This usually happens when the spinach hasn’t been squeezed dry enough, or the quiche hasn’t baked for the full time. Make sure you press the cooked spinach firmly in a tea towel, and always test the centre with a knife before pulling it from the oven.
