- Large eggs: The star binders that bring the quiche together with creamy structure.
- Whole milk: Incorporates moisture and tenderness into the custard.
- Shredded cheddar or Swiss cheese: Melts beautifully to add gooey texture and tang.
- Cooked spinach: Offers vibrant color and a nutritious boost; thawed and drained if frozen.

How to Make Crustless Spinach Quiche Recipe
Step 1: Preheat and Prepare Your Dish
Start by preheating your oven to 375°F. Then generously grease a 9-inch pie dish or any round baking dish to ensure your quiche doesn’t stick and comes out neatly after baking.
Step 2: Sauté the Aromatics
In a skillet heated over medium heat, warm the olive oil and add the finely chopped onion. Cook until it becomes soft and translucent, about 5 minutes, which builds a mildly sweet foundation. Add minced garlic and cook an additional minute to release its fragrance without burning. Remove from heat afterwards to keep flavors fresh.
Step 3: Mix the Custard and Filling
In a large mixing bowl, vigorously whisk the eggs and whole milk until fully combined and slightly frothy to create a luscious custard base. Fold in shredded cheddar cheese, cooked spinach, and the sautéed onion and garlic. Season with salt, black pepper, and a dash of nutmeg for extra flavor complexity.
Step 4: Assemble and Bake
Pour the egg and spinach mixture into your prepared pie dish, spreading evenly. Sprinkle the grated Parmesan cheese liberally on top to develop a golden, savory crust once baked. Place the dish in the oven and bake for 35 to 40 minutes until the center sets and the top turns a light golden brown.
Step 5: Cool and Slice
Allow your quiche to rest for 5 to 10 minutes once out of the oven. This resting step is crucial as it helps the filling firm up for easier slicing and enhances the dish’s flavors just before serving.
How to Serve Crustless Spinach Quiche Recipe

Garnishes
A simple sprinkle of fresh chopped herbs such as parsley or chives on top raises the presentation and adds a fresh, vibrant note that contrasts deliciously with the warm custard. You could also add a light dusting of cracked black pepper or a drizzle of olive oil for extra shine.
Side Dishes
This crustless dish pairs beautifully with bright, crisp salads or fresh fruit to balance the richness of the quiche. Roasted asparagus, cherry tomatoes, or a simple arugula salad tossed with lemon vinaigrette are perfect companions that keep the meal light and refreshing.
Creative Ways to Present
Try baking this quiche in individual ramekins for charming personal portions that are perfect for brunch parties. Alternatively, serve alongside crunchy artisan bread or make open-faced sandwiches with slices of quiche nestled on crusty toast to surprise and delight your guests.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover your leftover crustless spinach quiche tightly with plastic wrap or transfer it to an airtight container. Store in the refrigerator for up to 3 days, ensuring it stays fresh and flavorful for quick meals later in the week.
Freezing
This recipe actually freezes very well. Wrap portions individually in foil and place them in a freezer bag to avoid freezer burn. Frozen quiche slices can last for up to two months, making it a fantastic make-ahead option for busy days.
Reheating
For a delightful reheated meal, warm slices in a preheated oven at 350°F for about 10 to 15 minutes, or until heated through. This method retains the quiche’s texture best. Microwaving is quicker but might make the texture a bit softer.
FAQs
Can I use fresh spinach instead of frozen?
Absolutely! Fresh spinach works wonderfully. Just make sure to cook it down and drain well to remove excess moisture, which keeps your quiche from becoming too watery.
Is this Crustless Spinach Quiche Recipe suitable for a gluten-free diet?
Yes, since there’s no crust, this quiche is naturally gluten-free, making it an excellent choice for those with gluten sensitivities while still offering incredible flavor.
Can I add other vegetables or proteins?
Definitely. Feel free to mix in sautéed mushrooms, bell peppers, or cooked bacon to customize the dish to your liking. Just remember to cook any added ingredients beforehand to avoid excess moisture.
What can I do if I don’t have Parmesan cheese for the topping?
If Parmesan isn’t on hand, substitute with another hard cheese like Pecorino Romano or simply sprinkle extra shredded cheddar on top for a tasty golden crust.
How do I know when the quiche is fully baked?
The quiche is done when the center is set and no longer jiggles when you gently shake the pan, and the top has a light golden color. A toothpick inserted in the center should come out clean.
