Step 1: Prepare Your Ingredients

Preheat your oven to 350°F (175°C). While it’s heating, take out your eggs and dairy products to bring them to room temperature. This ensures a smoother mixture and more even cooking. Generously butter a 9-inch pie dish or quiche pan, making sure to get into all the corners and up the sides. The butter creates a natural barrier that helps prevent sticking and adds a subtle richness to the outer edge of your Crustless Quiche.

Step 2: Prepare Your Fillings

Now, prepare any mix-ins you’ll be using. If you’re including vegetables like spinach, mushrooms, or bell peppers, sauté them in a little olive oil until they’re just tender and any excess moisture has evaporated. Season them lightly with salt and pepper. For proteins like ham or bacon, make sure they’re fully cooked and cut into bite-sized pieces. Having everything prepped before mixing your egg base ensures you won’t be rushing once the custard is ready.

Step 3: Mix The Egg Base

In a large bowl, whisk the eggs until they’re completely blended. Pour in the heavy cream and milk, continuing to whisk until the mixture is uniform. Add the salt, pepper, and nutmeg, whisking to incorporate. The key here is to whisk thoroughly but gently – you want to blend everything without incorporating too much air, which can cause your Crustless Quiche to puff up dramatically in the oven and then collapse.

Step 4: Assemble And Bake

Scatter your prepared fillings evenly across the bottom of the buttered dish. Sprinkle about two-thirds of the cheese over the fillings. Carefully pour the egg mixture over everything, then top with the remaining cheese. The top layer of cheese will create a beautiful golden crust as it bakes. Bake for 45-50 minutes, or until the center is just set and no longer jiggles when gently shaken. The top should be golden brown and slightly puffed.

Step 5: Rest Before Serving

This step is crucial but often overlooked! Allow your Crustless Quiche to rest for at least 10 minutes before slicing. This gives the eggs time to fully set and makes for cleaner, more beautiful slices. If you cut into it too soon, it may be too soft in the center and fall apart. During this resting time, the quiche will continue cooking slightly from residual heat while the texture stabilizes.
