This recipe makes a big portion so it’s perfect for a crowd or leftovers. It’s easy to assemble and super delicious, perfect for every eater and designed especially for Primal, Keto, Low Carb and GAPS eaters.

Skillet Crustless Quiche

The main differences between a crustless quiche and a frittata are that a crustless quiche is baked in the oven, not started on the stove top, and more importantly, that a crustless quiche is loaded with cream. We must give thanks to the French who knew the pleasure, and even the healthfulness, that comes from using well-sourced fat in abundance. The texture of a quiche is completely, well, creamy. It’s soft and indulgent, with a bit of a crusty top. While frittatas are good, especially when served with homemade salsa, quiches belong to a different echelon.

I bake ours in a big cast iron skillet, giving it a rustic charm, great oven to table functionality and a large serving capacity. The skillet quiche has even more appeal (than a small crustless quiche baked in a pie plate) by allowing us to make a huge rustic quiche, so beautiful for a buffet, yet providing an easy prep and clean-up for the cook. (Cast iron skillets are the best for a quick clean-up!)

Christmas at our house

The first time I made this large skillet quiche was for a Christmas at my parents’ house.

My mom is Jewish.  All the Jewish people who’ve loved me have loved to feed me — large quantities!  So even though blintzes have been our traditional Christmas breakfast my entire life, that year my mom also made SIX pounds of homemade sausage patties, FOUR pounds of lamb chops, sourdough bread and butter, toppings for the blintzes, a huge fruit platter and asked me to bring the large crustless quiche. We had fifteen people.  Fifteen people and all that food! She is always worried we will not have enough!

I won’t mention the dinner feast. But suffice it to say: She is generous, anxious, and we all go home with LOTS of leftovers.

Today I’ll share that Crustless Quiche recipe with you! because it was really good and great for any holiday, gathering or just a house full of hungry eaters (like I always have these days). Plus it’s loaded with tons of veggies, which I love.

The grain-free blintz recipe mentioned above is now published in my cookbook!~ EAT BEAUTIFUL: Grain-free, Sugar-free and Loving It.  It’s one of my favorite recipes; and I hope you get to make it as well.

One more note about this Crustless Quiche recipe and its yumminess: cream and cheese + slow-cooked garlic = MMM. 🙂
