Ingredients
- Butter – Salted butter adds richness, but unsalted works just as well.
- Onion – Yellow or brown onions are best, but sweet onions work too. Red onions can be used, though they tend to lose their color when cooked. Eliminate the onions if you’re doing strict keto.
- Green bell pepper
- Red bell pepper – Any bell pepper variety will work, just ensure you have 1 cup total.
- Eggs – Extra-large eggs will work as well; this recipe is flexible.
- Heavy Whipping Cream
- Salt and few grinds of black pepper – Adjust to taste.
- Ham – A great way to use up leftover ham!
- Cheddar cheese – Sharp cheddar provides great flavor, but any cheese will do.
- Parsley, chives, sliced green onions, diced avocado, or salsa – Optional toppings.
How to Make Baked Western Omelet
- Set your oven to 350°F and grease a 10-inch square baking dish with nonstick spray.
- Melt the butter in a skillet over medium heat. Add the diced onions and cook until they start to soften, about 5 minutes. Stir in the bell peppers and cook for another 2 minutes. Remove from heat and let cool.
- Whisk together the eggs, cream, salt, and pepper until fully combined.
- Stir in the ham, shredded cheese, and the cooled sautéed vegetables.
- Pour the mixture into the greased baking dish and bake for 45 minutes to 1 hour, or until the eggs are set and fully cooked.
- Cut into squares and garnish with parsley, chives, green onions, avocado, or salsa if desired.

Chef’s Tips

- Add mushrooms, spinach, or tomatoes for extra texture and flavor.
- Cut into squares and store in an airtight container for a quick grab-and-go breakfast.
- A dash of cayenne or some chopped jalapeños will give it a bit of heat.
