Recipe Highlights

One day I had some leftover spinach dip in the fridge and wondered, "What could I make with this? How about a Spinach Dip Frittata?"

Not only did it work, it turned out to be the best brunch dish I've ever made. Everyone who tastes it says it's the most amazing crustless quiche they've ever had!

Over the years, it's been a big hit at special occasions like bridal brunches and Mother's Day. It's also one of the easiest and most delicious dishes you can make on Christmas morning.

This easy spinach frittata is so rich, you'll never miss the crust found in most quiche recipes. You'll love the creamy custard and velvety texture from the addition of sour cream. It goes really well with my Sundried Tomato Orzo Pasta, and Sassy Fruit Platter if you're feeding a big crowd.

Frittata vs Quiche

What's the difference between a frittata and a quiche? The main difference between the two is the crust. A frittata is basically a crustless quiche, while a traditional quiche has a thick crust on the bottom.

The word frittata is derived from Italy, while quiche is a classic French dish. Quiche is often made with heavy cream, while frittata recipes are sometimes made with less dairy.

Both are a type of egg custard that features different types of meats, vegetables and fresh herbs. The cooking method is different which also alters the cooking time. It takes less time to bake a frittata than a quiche since there is no crust involved.

This spinach frittata recipe is as simple as making a batch of spinach dip and adding 8 beaten eggs. The whole thing is that easy! Your guests will never know unless you tell them. But, they will definitely tell you it's the best thing they've ever eaten!
