Wait…You Can Bake an Omelette?
When you hear the word “omelette”, you likely think of the stovetop egg dish and not of a casserole-style recipe. But, we’re shaking things up and giving you an oven-baked version of this classic recipe.
You’ll find that a baked omelette is just as easy and yields equally delicious results. Plus, it can make enough “omelettes” for the whole family or a group. You can even use slices of it to make Breakfast Sandwiches.
Ingredient Notes
One of the beauties of this recipe is that the ingredients are easily customized to your liking. As long as you keep the ratios in our recipe below, your Oven Omelette will come out moist and tasty!
Here are the 5 main ingredients you will need to get started…
- Eggs – We used large eggs in this recipe.
- Cheese – While shredded cheddar is great, you can mix up the cheese you use. I’ve tested with feta, and it’s delicious!
- Milk – I’ve tested with 2% milk, half and half, and almond milk. All work!
- Veggies – You can use none, one, or several vegetables in your omelette. Some veggies like chopped spinach, fresh herbs, or roasted red peppers can go straight into the egg mixture uncooked. However, most veggies will need to be sautéed in advance, so they won’t turn out undercooked and crunchy. Here are some you will need to saute first:
- Onions
- Bell peppers
- Mushrooms
- Zucchini
- Asparagus
- Broccoli
- Cooked breakfast meat – Again, choose your own adventure. Or just add more veggies if you want to make it vegetarian. Here are some ideas:
- Chopped ham (a great way to use leftovers from Crockpot Ham)
- Breakfast sausage
- Bacon (try baking bacon in the oven to save on the mess).
Tip: Cook Once and Eat All Week!
You can easily double this recipe and store the leftovers in the fridge for busy week mornings. It works perfectly as a grab and go breakfast.
How to Make a Baked Omelette
Combine Ingredients
In a large mixing bowl, beat the eggs and milk until combined. Stir in cheese.
Now add your cooked and cooled veggies and meat.
Note: If you want to add spinach, this would be the time to do it.
Bake the Omelette
You will add your ingredients to a greased 9-inch baking pan. This can be glass or metal. If using glass, you might have to add a few minutes to our cooking time.
My Favorite Baking Pan
I can’t say enough good things about our Caraway Bakeware. I didn’t even have to use cooking spray for this recipe. The nonstick ceramic does all of the work for me!
Serve and Enjoy!
While the oven omelette is its very best right out of the oven, it makes great leftovers too. Serve it with our Classic Fruit Salad or one of our 7 Smoothies for a perfectly well-rounded breakfast!
Make It a Freezer Meal

Like so many of our freezer meal recipes, this egg dish will work beautifully as a make ahead breakfast.
To Freeze:
Assemble all of the ingredients together in a freezer container or freezer bag. Do not bake. Seal and freeze.
Bagwell Freezer Bag Stand
When a freezer meal recipe is large or has lots of liquid, I have found that this particular bag stand works best. It’s more secure and less prone to slipping or tipping over. Check it out!
Recipe FAQs
Absolutely! Just omit the veggies from the recipe and feel free to add more meat, if desired.
To make this recipe vegetarian, simple leave out the cooked meat. Instead, add more sautéed vegetables like chopped bell peppers, onions, mushrooms, sweet potatoes, potatoes, etc. Or add fresh chopped spinach and herbs, such as parsley or basil, without sautéing first.
Yes, a baked omelette is a great recipe to make ahead for the week. Once it’s baked and cooled, cover and store it in the refrigerator for up to 3-4 days. When you’re ready to serve, you can reheat slices in the microwave or a preheated oven.

Instructions
Make It Now:
- Prep: Preheat oven to 400°F degrees. Grease an 8×8 or 9×9 casserole dish with cooking spray.
- Saute Veggies: In a medium skillet, heat the oil over medium-high heat until shimmery. Add the diced veggies. Season lightly with salt and pepper. Stir occasionally until the vegetables are softened, about 4-5 minutes. Remove from heat and set aside. (This would also be a good time to cook the meat, if it isn’t already.)
- Combine: In a large mixing bowl, beat the eggs and milk until combined. Stir in cheese, veggies, and cooked meat. Note: If you want to add fresh chopped spinach or herbs, this would be the time to do it.
- Bake: Pour egg mixture into the casserole dish. Bake for 20-25 minutes, just until eggs are set in the middle. Let cool slightly before slicing.
Freeze For Later: Follow Steps 2-3. Pour the batter into a gallon-size freezer bag or into a greased square casserole dish with lid. Seal tightly and freeze. (Tip: Freeze the freezer bag on a sheet pan. Remove pan once it’s frozen.)
Prepare From Frozen: Thaw completely. Bake according to directions.
Notes/Tips
- Dairy-Free Version: Use plain non-dairy milk (i.e. almond milk) and omit the cheese or use dairy-free cheese like Daiya brand.
- Instead of sautéing the veggies, you can instead add them to a microwave-safe bowl and toss with oil. Cover with a paper towel and microwave for 4-5 minutes, until softened.
- I don’t recommend freezing this dish after baking, unless you cut it into slices to put on Breakfast Sandwiches. They freeze great!
- My favorite baking dish for this casserole is the Caraway Square Baking Pan. If you want to freeze it in a dish and bake later, try the Oxo Freezer-to-Oven Dish.

Looks yummy im gonna try the recipe
Would it be ok to make the night before and chill in the fridge before cooking in the morning. Trying to figure out some good healthy breakfasts for my family, but I have a horrible time trying to get up in the mornings!
Absolutely! This works well.
Had this last week and its in the oven again for tonight! Loved it that much! AND it was SO easy!!!
I want to make this and add hash brown potatoes to the mix? Would you add them frozen?
I haven’t added frozen hashbrowns to this particular recipe before, so I’m not sure. Has anyone else tried this?
I make something similar and I’ve found the normal loose hash browns don’t work well because they are pale bland and don’t have that nice crisp thing going. However frozen tater tots or the frozen hash brown patties work well since they are already crispy. I do add them still frozen. They work well putting it straight back in the freezer or in the fridge overnight to cook in the AM.
Ooo, good tip! My kids would love that. Thanks, Rachel
Just made today for a great Memorial Day breakfast. It was a hit with the whole family. The best part was it was so easy to make & tasted awesome. I put sautéd onions & peppers, spinach, bacon, green onion & cheese in mine.
Ooo, that sounds delicious. Can’t go wrong with more veggies and of course bacon and cheese.
Do you know if this freezes well? To be heated up as individual servings? I am the first one to leave the house in the mornings and am constantly looking for super easy breakfast solutions for my family. As long as they can grab it and nuke it, they will usually eat it!
Debbie, this really isn’t a great one to freeze ahead and reheat in the microwave. Gets a little tough. I would suggest trying the Breakfast Casserole Muffins, Savory Breakfast Muffins, Chocolate Banana Muffins (Version 2.0), and Breakfast Cookies if you want some freezable/reheatable options for the family. I make up a batch, let them cool completely, put them in a freezer bag. To reheat from frozen, cover with a moist paper towel and microwave in increments (start with 30-60 seconds and keep going until warmed through).
I love this idea. I “make” omelets every other day and I just want something easier.
For sure going to try this one!
