Ingredients

For the Quiche:

2 tbsp olive oil (30 ml)
1 small yellow onion, finely chopped (100 g)
3 cups fresh spinach, roughly chopped (90 g)
4 large eggs (200 g)
1 cup milk (240 ml)
1 cup shredded cheddar cheese (100 g)
½ cup grated Parmesan cheese (50 g)
½ cup ricotta cheese (125 g)
2 cloves garlic, minced (6 g)
½ tsp dried thyme (1 g)
½ tsp kosher salt (3 g)
¼ tsp black pepper (0.5 g)
¼ tsp ground nutmeg (0.5 g)

How to Make It

1. Prepare the Oven and Pie Dish

Preheat the oven to 375°F (190°C). Lightly grease a 9-inch (23 cm) pie dish with olive oil or nonstick cooking spray to help prevent the quiche from sticking.

2. Sauté the Onion and Garlic

Heat the olive oil in a skillet over medium heat. Add the finely chopped onion and cook for 4–5 minutes, stirring occasionally, until softened. Add the minced garlic and cook for another 30 seconds, just until fragrant.

3. Cook the Spinach

Add the chopped spinach to the skillet and cook for 2–3 minutes, stirring until wilted. Remove the skillet from the heat and let the mixture cool slightly. If there is excess liquid in the pan, drain it before continuing to help the quiche set properly.

4. Prepare the Egg and Cheese Mixture

In a large mixing bowl, whisk together the eggs, milk, cheddar cheese, Parmesan, ricotta, dried thyme, salt, black pepper, and ground nutmeg. Mix until the ingredients are evenly combined and the cheeses are distributed throughout.

5. Combine the Ingredients

Fold the cooked spinach, onion, and garlic mixture into the egg and cheese mixture. Stir gently to distribute the vegetables evenly without overmixing.

6. Fill the Pie Dish

Pour the mixture into the prepared pie dish and spread it evenly with a spatula. Gently level the surface so the quiche cooks uniformly.

7. Bake Until Set

Bake for 35–45 minutes, or until the centre is set, the top is lightly golden, and a knife inserted near the centre comes out clean. If the centre still appears too soft, continue baking for a few more minutes and check again.

8. Rest and Serve

Remove the quiche from the oven and let it rest for 10 minutes before slicing. This resting time helps the egg mixture firm up and makes serving easier. Enjoy warm or at room temperature for breakfast, brunch, lunch, or a simple family dinner.

Why This Recipe Works

This crustless quiche combines eggs and milk to create a tender, savoury base without the need for pastry. Ricotta adds creaminess, cheddar brings a familiar cheesy flavour, and Parmesan contributes a savoury depth that complements the spinach and garlic.

Cooking the spinach before adding it to the egg mixture helps remove excess moisture, which is essential for a quiche that sets properly. The onion adds natural sweetness, while thyme and nutmeg bring gentle aromatic flavours that make the finished dish especially comforting.

Tips for the Best Crustless Spinach & Cheese Quiche

Remove excess moisture: Drain the cooked spinach mixture if needed. Too much liquid can prevent the quiche from setting firmly.
Let the vegetables cool slightly: Allowing the spinach and onion mixture to cool before combining it with the eggs helps the ingredients blend evenly.
Use freshly grated cheese: Grating cheddar and Parmesan yourself can help them blend more smoothly into the mixture.
Avoid overbaking: Remove the quiche once the centre is set and the top is lightly golden to help keep the texture tender.
Allow time to rest: Resting for 10 minutes makes the quiche easier to slice and serve neatly.
Season to taste: Parmesan and cheddar both contribute saltiness, so adjust the salt slightly if preferred.

Serving Suggestions

Serve a warm slice of crustless spinach and cheese quiche with a fresh green salad, sliced tomatoes, or roasted vegetables for a balanced lunch or light dinner. For breakfast or brunch, pair it with wholegrain toast, fresh fruit, or sautéed mushrooms.

This quiche also works well on a brunch table alongside roasted potatoes and other simple dishes. Finish with a sprinkle of fresh herbs, such as parsley or chives, if you would like a fresh touch before serving.

Frequently Asked Questions

Why is my crustless quiche watery?

Excess moisture from the spinach is a common reason. Cook the spinach until wilted and drain any liquid before mixing it with the eggs. Also, make sure the quiche is fully set before removing it from the oven.

Can I make this quiche ahead of time?

Yes. Bake the quiche, let it cool, and refrigerate it in a covered container. Reheat individual slices gently in the oven or microwave, or serve them chilled or at room temperature if preferred.

Can I use frozen spinach?

Yes. Thaw the spinach completely and squeeze out as much liquid as possible before adding it to the sautéed onion and garlic. This helps maintain the right texture.

Can I substitute the cheeses?

You can use other melting cheeses in place of cheddar, such as mozzarella or Gruyère. Ricotta contributes a creamy texture, while Parmesan adds a savoury flavour, so changing these cheeses will slightly alter the final result.

How do I know when the quiche is ready?

The edges should look set, the top should be lightly golden, and the centre should no longer appear liquid. A knife inserted near the centre should come out clean. Let the quiche rest for 10 minutes before slicing.

How should I store leftovers?

Allow the quiche to cool, then place it in an airtight container and refrigerate for up to 3–4 days. Reheat portions until warmed through. Avoid leaving cooked eggs and dairy at room temperature for more than two hours.
