We're approaching casserole season. Casseroles are really one of my favorite types of dishes - mostly because they're easy, delicious and taste even better when eaten the next day.

This Oven Baked Omelette falls in the casserole category, in my opinion, because it's a one pan meal, perfect for serving a crowd and heats up well the next morning. I love that this is baked RIGHT IN THE OVEN!

When I say this feeds a crowd, I mean it. The omelette, itself, uses 18 eggs.

Once you have the eggs whisked, you start mixing in all of the other goodies. . .ham, green peppers, onions, cheese, mushrooms, etc.

I call it the ultimate oven baked omelette because you can really throw anything in there that appeals to you. Dice up some jalapeños and add those to the omelette if you want to add a little heat!

Once you have everything mixed together, you just pour it into a greased 13x9" baking pan. I use butter to give it a little more flavor and make sure to brush the sides of the pan in addition to the bottom for easy removal after the omelette is baked.

I also like to divide the shredded cheese, so I mix half in with the rest of the ingredients and sprinkle the remaining cheese on top before I pop it into the oven.

It takes a little over an hour to bake, but when it's finished, it's golden brown and ready to eat.

And it cuts beautifully.

It's perfect for a brunch, party or the holidays when you're serving a group of people.

And I'm pretty sure it would go over well with the guys, too. Serve it alongside some toast or pancakes and fresh fruit, and everyone should be happy.

So, if you're not sure what you're making for breakfast tomorrow, give this ultimate oven baked omelette a try!

Notes

Customize Ingredients: The beauty of this oven-baked omelette recipe is its versatility. Feel free to customize the ingredients to suit your taste preferences or dietary restrictions. Swap out the suggested vegetables and protein for your favorites, or add additional ingredients like spinach, tomatoes, or cooked bacon. Make it your own by experimenting with different flavor combinations.
Even Distribution: Ensure that all the ingredients are evenly distributed throughout the egg mixture to ensure each bite is flavorful. After mixing everything together, use a spatula to spread the mixture evenly in the baking pan. This helps prevent any pockets of ingredients from clumping together, resulting in a more uniform texture and taste in the finished dish.
Proper Baking Time: Since ovens can vary in temperature, it's essential to monitor the omelette closely during baking to avoid overcooking or undercooking. The omelette is ready when it's set in the center and lightly golden brown on top. Use a toothpick or knife inserted into the center to check for doneness; if it comes out clean, the omelette is cooked through. Adjust the baking time as needed based on your oven's characteristics.
