What Is a Baked Denver Omelette?

A baked Denver omelette is an oven-cooked egg dish made by combining beaten eggs with ingredients such as cheese, vegetables, and meat.

Unlike traditional stovetop omelettes, which are usually cooked individually and folded over their fillings, a baked Denver omelette is prepared in a casserole dish and cut into individual servings.

It’s similar to a frittata, but this version is made entirely in the oven after the fillings have been sautéed.

The result is a thick, tender, cheesy omelette that’s easy to serve and perfect for feeding several people at once.

Ingredients You’ll Need

This recipe uses simple ingredients that come together to create a flavorful, satisfying breakfast.

Eggs

You’ll need 8 large eggs for this recipe. They create the base of the omelette and provide structure as it bakes.

Whole Milk

⅓ cup whole milk helps create a tender egg mixture without making the omelette overly soft or watery.

Ham

You’ll need 1 cup of diced, fully cooked ham (approximately 5–6 ounces) for this recipe. You can use smoked ham, uncured ham, leftover holiday ham, or your favorite ham steak.

Keep in mind that some varieties of ham are saltier or more heavily seasoned than others, so you may want to adjust the additional seasonings accordingly. 

Red and Green Bell Peppers

You’ll need ⅓ cup each of diced red and green bell peppers.

The red bell pepper adds a little sweetness, while the green bell pepper provides that familiar, slightly earthy flavor often found in traditional Denver omelettes.

Onion

Use ⅓ cup diced yellow onion.

Sautéing the onion before baking helps soften its texture and bring out its natural sweetness.

Fresh Garlic

1 large clove of minced garlic adds another layer of savory flavor.

I prefer adding the garlic near the end of sautéing so it becomes fragrant without burning.

Sharp Cheddar Cheese

You’ll need 3 ounces of sharp cheddar cheese, freshly shredded

Sharp cheddar gives this omelette a rich, tangy cheese flavor.

Monterey Jack Cheese

Use 2 ounces of Monterey Jack cheese, freshly shredded.

Monterey Jack has a mild, buttery flavor and melts beautifully, complementing the stronger cheddar.

Badia Complete Seasoning

For a savory, herb-seasoned omelette, use ¾ teaspoon Badia Complete Seasoning, divided between the sautéed ingredients and the eggs.

If you prefer a milder seasoning flavor, start with ½ teaspoon total. Keep in mind that the ham and cheese already add plenty of flavor.

Black Pepper

Use ¼ teaspoon ground black pepper, or adjust to your preference.

Butter

You’ll need 1½ tablespoon of unsalted butter for sautéing the vegetables.

The butter adds richness and helps the peppers and onions cook until tender.

How to Make a Baked Denver Omelette

This recipe comes together in a few simple steps.

Step 1: Preheat the Oven

Preheat your oven to 350°F.

Lightly grease an 8½ × 8½-inch oven-safe glass casserole dish with unsalted butter or nonstick cooking spray.

Set aside while preparing the ingredients.

Dice 1 cup of fully cooked ham into small, bite-sized pieces, approximately ¼-inch cubes.

If you’re using a ham steak or a larger piece of leftover ham, trim away any tough edges before dicing.

Set the ham aside while you prepare the vegetables.

Step 3: Sauté the Vegetables

Melt 1½ tablespoon of butter in a skillet over medium heat.

Add the diced red bell pepper, green bell pepper, and onion.

Sauté for approximately 3–5 minutes, stirring occasionally, until the vegetables begin to soften.

Add the diced, fully cooked ham and continue sautéing for another 1–2 minutes, allowing the ham to warm through and develop a little golden color around the edges.

Next, add the minced garlic and ½ teaspoon of Badia Complete Seasoning.

Cook for another 30–60 seconds, stirring frequently, until the garlic becomes fragrant.

Remove the skillet from the heat and allow the mixture to cool slightly before assembling the omelette.

Step 4: Prepare the Egg Mixture

Crack 8 large eggs into a large mixing bowl.

Add ⅓ cup whole milk, the remaining ¼ teaspoon of Badia Complete Seasoning, and ¼ teaspoon black pepper.

Whisk until the yolks and whites are thoroughly combined and the mixture looks uniform.

Avoid beating the eggs excessively. You want everything well combined without creating too much foam.

Step 5: Assemble the Omelette

Spread the sautéed ham and vegetables evenly across the bottom of your prepared 8½ × 8½-inch casserole dish.

Combine the shredded sharp cheddar and Monterey Jack cheeses.

Sprinkle approximately half of the cheese mixture over the ham and vegetables.

Slowly pour the seasoned egg mixture over the fillings, allowing the eggs to flow between the ingredients.

If necessary, gently move the fillings around with a fork to help distribute everything evenly.

Sprinkle the remaining shredded cheese over the top. 

Step 6: Bake

Place the casserole dish on the center rack of your preheated oven.

Bake uncovered at 350°F for approximately 30–40 minutes, or until the center is set and the eggs reach an internal temperature of 160°F.

The edges may puff up as the omelette bakes. This is completely normal!

If the center needs additional time, continue baking in short intervals until fully cooked.

Step 7: Rest and Serve

Remove the baked omelette from the oven and allow it to rest for 10 minutes before slicing.

During this time, the eggs will settle slightly, making the omelette easier to cut into neat squares.

Serve warm and enjoy!

Tips for the Best Baked Denver Omelette

Sauté the Vegetables First

Cooking the peppers and onions before adding them to the eggs improves their flavor and helps reduce excess moisture.

Don’t Overmix the Eggs

Whisk until the eggs and milk are thoroughly combined. There’s no need to beat them until extremely frothy.

Shred Your Own Cheese

Freshly shredded cheese generally melts more smoothly than packaged shredded cheese, which often contains anti-caking ingredients.

Watch the Seasoning

Ham and cheese already contain salt, so be careful when adding seasoned blends.

It’s easier to add more flavor than to correct an overly salty omelette.

Don’t Overbake

The omelette should be set in the center but still tender.

Overbaking can cause the eggs to become dry or rubbery.

Let It Rest Before Slicing

Allowing the omelette to rest for 10 minutes makes it easier to cut and serve.

Easy Variations

One of the best things about a baked Denver omelette is how easily you can change the ingredients.

Sausage and Cheese Omelette: Replace the ham with cooked, crumbled breakfast sausage.

Vegetarian Omelette: Leave out the meat and add mushrooms, spinach, or other vegetables.

Extra Cheesy Omelette: Add a little additional shredded cheddar if you prefer a stronger cheese flavor.

Simple Seasoned Omelette: Skip the Badia Complete Seasoning and use salt and black pepper to taste. Start with a small amount of salt, since the ham and cheeses are already salted.

What to Serve With a Baked Denver Omelette

This omelette is filling enough to enjoy on its own, but it also pairs beautifully with classic breakfast sides.

Some of my favorites include:

• Crispy hash browns or breakfast potatoes
• Buttered toast
• Homemade biscuits
• Fresh fruit
• Pancakes or waffles

If you’re serving this omelette with bacon or another salted side dish, I recommend keeping the seasoning on the lighter side.

How to Store and Reheat Leftovers

Refrigerating

Allow the omelette to cool, then transfer leftovers to an airtight container.

Refrigerate within 2 hours of cooking and store for up to 3–4 days.

Reheating

Reheat individual portions in the microwave in short intervals until heated thoroughly to 165°F.

You can also reheat portions in a covered oven-safe dish at 325°F until heated through.

Freezing

For longer storage, wrap individual cooled portions tightly and place them in a freezer-safe container or bag.

Freeze for approximately 1–2 months for best quality.

Thaw overnight in the refrigerator before reheating.

Keep in mind that the texture may become slightly softer after freezing and reheating.

Frequently Asked Questions

Can I make a baked Denver omelette ahead of time?

Yes! You can prepare the cooked fillings and shred the cheese the night before.

Store everything separately in the refrigerator, then whisk the eggs and assemble the omelette when you’re ready to bake.

How do I know when my baked omelette is done?

The center should be set without visible liquid egg.

For food safety, check that the thickest part reaches an internal temperature of 160°F.

Can I make this recipe without milk?

Yes. You can omit the milk for a slightly firmer, more egg-forward texture.

Can I use only cheddar cheese?

Yes! If you don’t have Monterey Jack, you can substitute additional cheddar.

However, I enjoy combining the two because cheddar adds bold flavor while Monterey Jack provides a mild, creamy melt.
