This Keto Baked Western Omelet is what I make when I need breakfast to cover more than one morning at once. Eggs, ham, cheese, and bell peppers bake into one dish, and it slices into squares that reheat well all week long.

I lean on this one for meal prep, holidays, or any morning I’m feeding more than just myself. It’s endlessly adaptable, swap the ham for sausage or bacon, change up the cheese, or load in extra vegetables depending on what’s in the fridge.
Kids tend to eat this cold straight from the container, which makes it an easy grab-and-go option on busy mornings.
Chef Jenn’s Take on Keto Baked Western Omelet
A lot of baked egg dishes come out either watery in the middle or rubbery on the edges, because the egg-to-dairy ratio isn’t dialed in and the vegetables go in without any prep first. Get either of those wrong and the texture suffers even if the flavor is fine.
Cooking the onion and peppers first and letting them cool before they go into the egg mixture is what keeps this from turning watery. Raw vegetables release moisture as they bake, and that moisture has nowhere to go once it’s trapped inside a custard. Sauté first, cool, then mix in, and the texture holds together instead of pooling liquid in the pan.
What You’ll Love About Keto Baked Western Omelet
- It makes eight servings from one pan, so it covers a full week of breakfasts instead of just one morning.
- It’s endlessly adaptable, swap the protein, the cheese, or the vegetables, and it still works every time.
- It reheats well and even holds up eaten cold, so it travels easily for anyone who needs breakfast on the go.
Ingredients
- Butter – Salted or unsalted both work, just adjust the added salt slightly if using salted.
- Onion – Yellow or brown onion works best. Skip it entirely for a stricter low-carb approach if you prefer.
- Green bell pepper
- Red bell pepper – Any bell pepper color works, just keep the total to about 1 cup.
- Eggs – Large or extra-large both work fine here.
- Heavy whipping cream
- Salt and black pepper – Season to taste.
- Ham – A good way to use up leftover holiday ham.
- Cheddar cheese – Sharp cheddar gives the most flavor, but any melting cheese works.
- Fresh parsley, chives, sliced green onion, diced avocado, or salsa – Optional toppings.
How to Make Baked Western Omelet

Preheat the 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 onion and cook until it starts to soften, about 5 minutes. Stir in the bell peppers and cook another 2 minutes, then remove from heat and let the mixture cool. Cooling this step matters, adding hot vegetables straight to the eggs can start cooking them too early and throw off the texture.
Whisk together the eggs, cream, salt, and pepper in a large bowl until fully combined.
Stir the ham, shredded cheddar, and cooled sautéed vegetables into the egg mixture.
Pour into the greased baking dish and bake for 45 minutes to 1 hour, until the eggs are set and fully cooked through. Cut into squares and garnish with parsley, chives, green onion, avocado, or salsa if desired.
Make it a Meal
I serve this with buttered low-carb toast or a crisp green salad on the side for a full meal. Round it out with Egg Bites with Spinach & Cheese if you’re feeding a crowd and want extra breakfast options on the table. For a different take on baked eggs, Baked Eggs Florentine with Ham makes a good rotation partner so breakfast doesn’t feel repetitive during a big meal-prep week.
Storage
Store leftovers in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave for 30 to 40 seconds, or in the oven at 350°F for about 10 minutes. This freezes well for up to 2 months. Thaw overnight in the fridge before reheating.
FREQUENTLY ASKED QUESTIONS
Yes, a 9×13-inch dish works and cuts the bake time down to around 30 minutes since the mixture spreads thinner. A 10-inch square dish gives you a thicker, taller square per serving.
Yes, cooked sausage or crispy bacon both work well as a substitute. Just make sure the protein is fully cooked before stirring it into the egg mixture.
This usually happens when raw or undercooled vegetables go straight into the egg mixture. Sautéing the onion and peppers first and letting them cool before mixing helps prevent excess liquid from pooling as it bakes.
Yes, it holds up well cold straight from the fridge, which makes it an easy grab-and-go breakfast for kids or busy mornings.
