Garden Harvest Frittata

Why This Garden Harvest Frittata Works

As the eggs and milk are whisked together, they trap a bit of air and loosen up, so they pour easily around the vegetables. In the hot skillet, the onion, zucchini, and bell pepper soften and lose some water. They shrink a little and sit closer together, so later the eggs can slide into all the gaps instead of pooling in one spot.

Once the egg mixture goes into the pan, it starts to set first around the edges where the heat is strongest. The eggs slowly firm up around the vegetables and hold everything in one solid piece instead of falling apart like a scramble. Feta and basil stay mostly on top, so they sink in just a bit as the eggs thicken.

In the oven, gentle heat finishes the job. The center of the frittata firms up without drying out, since the vegetables still have some moisture inside them. After it comes out and sits for a few minutes, the eggs finish setting, so slices cut cleanly and the vegetables stay tucked into place.

Mistakes To Avoid

Letting the skillet go into the oven with very runny eggs in the center can cause trouble. The edges will overcook and turn rubbery while the middle still jiggles and stays wet, so by the time the center sets, the outside is tough and dry instead of soft all the way through.

When the vegetables are barely cooked before the eggs go in, they keep releasing water in the oven. The eggs then steam instead of setting cleanly, so the frittata can look watery around the vegetables and feel soggy instead of firm and sliceable.

Using high heat on the stove for the first cook can scorch the bottom. The eggs grab and brown too fast underneath while the top is still loose, so the finished frittata has a dark, hard crust and a strangely layered texture.

Adding the basil at the very start with the onions makes it wilt down to almost nothing. By the time the frittata is baked, the leaves turn dark and stringy and disappear into the eggs instead of sitting as soft, visible bits on top.
