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 .
Where to Get Your Ingredients
We suggest grabbing the ingredients for this recipe at your local Hy-Vee , since they are well-stocked year-round. The employees are always so helpful, if you have any questions. Save time by ordering your groceries for pick up or delivery using Aisles Online .
Ingredient Notes
One of the beauties of this recipe is that the ingredients are easily customized to your liking. As long as you keep these ratios, your Oven Omelette will come out moist and tasty!
Here are the 5 main ingredients you will need from Hy-Vee 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. Aside from spinach or roasted red peppers, veggies will need to be sautéed in advance . Otherwise, they will be undercooked and crunchy. Here are some other options:
Onions
Bell peppers
Mushrooms
Zucchini
Asparagus
Tomatoes
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.

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!

FAQs
Can I make this baked omelette without vegetables? Absolutely! Just omit the veggies from the recipe and feel free to add more meat, if desired. How do I make a vegetarian baked omelette? 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.

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
