Tips & Tricks for the Best Crustless Vegetable Quiche

Chop veggies small: Small pieces blend better and help the crustless vegetable quiche bake evenly.
Drain moisture: Use a paper towel to blot spinach or zucchini so your quiche isn’t soggy.
Whole milk = better texture: While any milk works, whole milk adds a touch of creaminess that makes this quiche extra satisfying.
Cheese strategy: Mix some in, then sprinkle more on top for that golden finish.
Check for doneness: A clean knife in the center means your crustless vegetable quiche is ready.

Can I prep this ahead of time?

Definitely. You can assemble it the night before or bake the full quiche and store slices in the fridge for up to 4 days. It reheats beautifully, which makes this recipe great for meal prep.
