Slice of omelet baked in the oven.

Back in my younger days, one of my favorite things to do with friends was head over to Shoney’s on Wednesday nights because that was the night where they served their breakfast buffet for dinner. To a teenager, this was pure bliss and our night out became a tradition I carried forward after I got married.

While I don’t get to eat my beloved French toast sticks as often these days, I’m still a huge fan of breakfast for dinner. In fact, those two-ingredient banana pancakes have become one of the go-to quick meals in my house. Today I thought I’d show you my favorite easy omelet that’s baked in the oven and ready to eat in 40 minutes. Every slice is creamy, fluffy, and cheesy perfection.

The ingredients are really simple (just eggs and milk) and you can customize your omelet to your own tastes. Isn’t that the cool thing about omelets? While I’ve opted for a combination of turkey sausage, cheddar cheese, and peppers/onions, I also think an omelet with roast beef, peppers, and mozzarella cheese would be divine. I gotta get around to doing that one day!

You’ll find a list of customization ideas down below, so let’s get cooking and make ourselves a delicious fluffy omelet in the oven!

Helpful Kitchen Tools

Eggs in a bowl

Crack all your eggs into the bowl.

Now listen, I know this recipe calls for eight but if you only have six, just go ahead and make it with six. Don’t go running out to the store to get more eggs just for this. I think the best dishes are the ones you make do with, that is how all of the good recipes came about anyhow.

Add milk to eggs in mixing bowl.

Add your milk to the scrambled egg mixture.

I’m using whole milk, but 2% or even skim milk will work just fine.

Whisk together eggs and milk.

Whip it, whip it good!

If you just smiled and did a little dance when you read that, you dated just dated yourself!

Add cheese to mixing bowl.

Add the cheddar cheese to the milk and egg mixture.

Add turkey sausage to mixing bowl.

Then add the turkey sausage to the beaten eggs.

Add pepper and onions to mixing bowl.

Add in your peppers and onions.

I use about a cup of the mixed variety.

Mix all omelet ingredients together.

Mix that up as well.

Prepared dish

Here is my 8×8 pan, already sprayed with cooking spray.

Pour omelet into prepared dish.

Pour the omelet into your prepared dish. Wasn’t that easy?

Now, instead of standing over the stove and watching this cook in a skillet, all we have to do is pop it in the oven and go about our day.

Bake your easy omelet in a 350-degree oven for about 40 minutes, or until it no longer wiggles in the middle when you shake it a bit.

Dinner’s ready! I like to serve a slice of baked omelet with a dollop of sour cream on top and season with salt and black pepper to taste.



  • Store omelet leftovers in an airtight container in the fridge for up to 4 days. Simply reheat in the microwave before serving.
  • You can also freeze cooked portions for up to 3 months. Thaw in the fridge before reheating in the microwave.

Customize Your Omelet

Here are some easy substitutions and additions to customize this baked American omelette recipe and make it your own:

  • Substitute a cup of your favorite veggies for the onion and bell pepper blend. I recommend chopped mushroom, spinach, tomatoes, green onion, or red onion.
  • Use your favorite shredded cheese in place of the cheddar cheese, like mozzarella cheese, Swiss cheese, or Pepperjack cheese.
  • Add in leftover meat in place of the turkey sausage. You could also use baked ham or bacon.
  • Top your easy omelet with salsa, Hollandaise sauce, avocado, extra shredded cheese, sour cream, or hot sauce.
  • Add in some extra flavoring through different seasonings and fresh herbs. This might include fresh parsley, oregano, garlic powder, red pepper flakes, or paprika.

Recipe Notes

  •  I love onions and bell peppers and I also love shortcuts. So sometimes I just buy this bagged mix of them unless I already have the peppers on hand. You can often find a mix of onions and bell peppers in the freezer section under the name of seasoning mix or pepper and onion blend.
  • Make a breakfast sandwich and place your slice of omelet between two pieces of toast or an English muffin. Serve with spinach and one of the sauces mentioned above.
  • Top your slice of omelet with a slice of cheddar cheese and quickly heat it in the microwave for something different.
  • You could also serve a slice of your easy omelet with a refreshing and light side salad.
  • For a slightly healthier version, you can use half egg yolks and half egg whites.
