Cheesy Broccoli & Spinach Quiche

Why This Cheesy Broccoli & Spinach Quiche Works

In the pan, the broccoli and spinach hit the hot olive oil and soften. They lose some water and shrink a bit, so they don’t water down the quiche later. The greens also warm up, so when they go into the crust they spread out in an even layer instead of clumping.

In the bowl, the eggs, milk, and ricotta blend into a smooth liquid. Once that mixture goes into the hot oven, the eggs slowly firm up. As they set, they trap the milk, ricotta, and vegetables in place, so the quiche slices cleanly and doesn’t fall apart. The ricotta keeps the egg layer soft instead of rubbery.

On top, the cheddar melts and flows over the surface. As it keeps baking, the cheese starts to brown, which gives a slightly crisp top while the inside stays tender. Letting the quiche sit for a few minutes after baking lets the hot egg and cheese settle, so the center finishes setting and the slices hold together.

Mistakes To Avoid

Pouring the egg mixture into a cold, raw pie crust straight from the package can lead to a soggy bottom. The crust doesn’t have a chance to firm up before the wet filling soaks in, so it bakes up pale and soft instead of holding its shape when sliced.

Letting the quiche bake until the top is very dark and the center is puffed high causes the eggs to overcook. As it cools, the center sinks and the texture turns rubbery and dry instead of soft and custardy.

Adding the vegetables without sautéing them first leaves too much water in the filling. In the oven, that water leaks out, so the quiche can look set on top but stay wet and slightly runny in the middle, with a watery layer at the bottom.

Skipping the 10-minute rest and cutting into the quiche right away makes the slices collapse. The hot filling hasn’t finished setting, so it runs out of the crust and the pieces look messy and loose instead of holding neat wedges.
