Quiche vs. Frittata

While a crustless quiche and a frittata are made up of similar ingredients (eggs, dairy, and add-ins), they are different things. The main difference comes from the baking techniques. Quiches are baked like tarts, in a pie pan in the oven. While frittatas are first cooked like an open-faced omelet in a cast-iron skillet, and then transferred to the oven for the last few minutes of the bake.

“I used sharp cheddar for this recipe. Other than that, I followed it exactly and it was DELICIOUS! This is definitely going into my recipe rotation,” says JDRABIK.

“My hubs and 14yo son are gobbling it up! I used fresh spinach with a pinch of nutmeg and added an extra egg. I used cheddar because that’s all I had. Served with fried potatoes. They both want it again, that’s high praise,” raves Donna Patterson.

“This is delicious. I made it today and my 9 year old daughter almost ate the entire thing. I used regular cheddar cheese, added a little nutmeg, 2 crushed cloves of garlic, some red pepper for color and an 8oz container of sour cream. I also added the salt and pepper to the spinach. WONDERFUL,” according to Louise McKay-Edwards.
