- Chop all of the vegetables into small pieces and shred the cheddar cheese. Save some time with a bag of shredded cheese.
- Mix the eggs with the milk (if using), cheddar cheese, salt, and pepper. Add the chopped veggies and give it a good stir.
- Pour into a greased casserole dish and top with additional cheddar. Bake for 35 minutes, or until the center no longer wiggles. The time it takes will depend on the size of your pan. When finished, top your tasty omelette with additional tomatoes and cheese if you'd like.
Kristina's Tips
For an 8 x 8 pan, my oven took 40 minutes to fully cook my baked omelet. In a 9 x 13 pan, it took 33. You can also test if it's done by inserting a toothpick into the center.
How To Store
Fridge: Oven baked omelettes will keep in the fridge for 3-4 days in a covered casserole dish.
Freezer: Store in the freezer for up to 6 months. Store individual slices in freezer-safe storage containers for quick and easy defrosting when you want breakfast quick later on.
Thawing: Defrost overnight in the fridge. The omelette will be a little watery after it's defrosted. Squeeze it between paper towels before warming up in the toaster and the water will not be an issue.

I made the Baked Omelette recipe yesterday and it is total yum! I used an ~8½x6½-inch casserole dish. Next time, I'll use a larger square inch dish to get a thinner "omelette". Thank you for this great recipe!
