This Cheese Omelet was one of my mom’s go-to Lenten recipes. Not a typical Omelet, it’s absolutely delicious, and simply made from eggs, cheese, and bread!

Though more like a Cheese Souffle than an omelet, the egg whites are whipped separately to give a delightful lightness to this easy vegetarian recipe.

Why You Must Make

Most of my recipes can be found in binders, all printed off the computer over the past 15 years or so. But I have a few treasured note cards in my recipe box, in my mom’s handwriting. This Cheese Omelet is one of those.

  • I make this cheese omelette every Lent when a meatless meal is needed.
  • It’s made with a simple mixture of cheese, eggs, and bread; it is easy and tasty.
  • Not quite an omelet, yet not quite a soufflé recipe. But it’s quite delicious!

Ingredient Notes

  • Kitchen Staples – Milk, Salt, Freshly Ground Black Pepper
  • Bread – 4 slices. Use sandwich bread, brioche or challah. I don’t recommend whole wheat bread for this recipe.
  • Butter – Have at room temperature to butter the bread and the souffle dish.
  • Grated Cheese – I use sharp cheddar. Gruyere would be tasty, too. 
  • Eggs – Separate when cold since the yolks are less likely to break. Let the whites come to room temperature for the best volume when whipped. Make sure the bowl for whipping is free of grease or the whites won’t beat properly. The bowl and beaters have to be very clean, too.

Recipe Tips

  • Slice your bread into ¾ to 1-inch pieces, leaving the crusts on. Use hearty bread so it does not completely disintegrate when the milk is added. My mom used sandwich bread when making this cheese souffle recipe, so it is an alternative.
  • Make sure to butter the bread before slicing. No one wants to deal with buttering individual bread cubes!
  • PRO-Tip – As with meringue, make sure your bowls and utensils are grease-free before beating the whites. Even a speck of egg yolk contaminating the whites will prevent them from whipping properly.
  • Whip the whites until they’re white and fluffy, then use a rubber spatula to gently fold them into the bread, cheese, and yolk mixture.
  • PRO-Tip – Don’t overmix as it will deflate the egg whites.
  • Sharp Cheddar cheese was my mom’s cheese of choice, but so many varieties would work well. Monterey Jack, Gruyere, or even a Pepper Jack would be delicious.
  • If you want a crusty or brown topping, place the souffle under the broiler for a minute or so, watching carefully so it doesn’t burn.

Frequently Asked Questions

What’s the Difference Between a Souffle and an Omelet?

A French Souffle Recipe is an egg dish with whipped egg whites and egg yolks combined with other ingredients to make either a savory or sweet dish. This Cheese Omelet fulfills the souffle definition.
On the other hand, an omelet is also an egg dish but can be made in a couple of different ways. An omelet, or omelette, is made of beaten eggs, sauteed in oil or butter, then folded over other ingredients like cheese, meats, herbs, and/or vegetables. Unlike scrambled eggs, the mixture is not stirred while cooking. A French omelet is made by a special technique where eggs are stirred with a fork while cooking and the pan is also shaken. This results in a fluffier consistency and is removed from the heat slightly underdone.

What Are the Different Kinds of Omelets?

Upon further investigation, there are four categories of omelets: American, French, Frittata, and Souffle. So it all makes sense now!

Does This Omelet Need a Collar?

No, this omelet will not collapse like a chocolate omelet due to the structure provided by the bread. A collar, made of foil or parchment, gives light and fluffy dessert omelets something to cling to as they rise, helping increase their height.

More Meatless Entrees for Lent

Perfect for Lent, but also lovely when looking for a vegetarian entree to work into your menu. The cheese and eggs provide plenty of protein and are fine to eat if you’re a lacto-ovo vegetarian. Here are some more meatless meals you’ll love:
