This breakfast casserole takes me back to my childhood in Ohio. After church every Sunday my family would eat at Bob Evan’s restaurant. I ordered their Denver omelette (now called their Western omelette) with a side of fried potatoes and wheat toast almost every single time.

What is an Omelette [omelet] ?

Omelettes are beaten eggs cooked (not scrambled) in butter or oil. Most omelettes are filled with ingredients like vegetables, meat, and cheese and then folded in half before serving. The thing I love about omelettes are that you can tailor them to your liking. They can be made plain, savory, or even sweet. Obviously this is not a traditional omelette for 2 reasons. One, it’s in casserole form. And second, it’s either baked or slow cooked.

The Denver Omelette

A Denver omelette is also known as the Western or Southwestern omelette. In addition to the eggs, the main ingredients in a Denver omelette are diced ham, bell peppers, onion, and cheese. Like all omelettes, there are of course variations to this.

FAQs & Tips

  • I used half red & half green bell pepper to be fancy but you don’t have to use two different peppers you can just use one.
  • Use the milk of your choice.
  • To make this paleo and Whole30 compatible, use almond milk and omit the cheese (or sub nutritional yeast). 
  • Store leftovers in the refrigerator for up to 4 days. 
  • A modified version of this recipe appears in my 1st cook book, The Easy & Healthy Slow Cooker Cookbook.
  • I used a 6-quart slow cooker for this recipe.

Can I do this in an InstaPot egg bites dish? What changes would I need to make and how long would I cook it? I just got an InstaPot and am still learning how to use it.

Has anyone doubled the recipe and cooked it overnight? If so did it turn out okay or how would/did you modify the cooking time?

I actually have:-) I'm in the middle of updating the recipe for a larger 6-quart slow cooker. Using 12 large eggs, it will need to cook low 6-8 hours. Mine was done after 7 hours on low.
