Blair Lonergan’s solution to omelet duty is beautifully direct: put the whole Western lineup—ham, cheddar, onion, green pepper, red pepper—into one egg mixture, slide one square dish into the oven, and return with breakfast for nine.

The original 2015 formula does not need extra flour, a potato crust, or a skillet prelude. Its ease depends on small cuts, even distribution, and a patient read of the center. Begin checking at 45 minutes; let the set and temperature decide whether the dish needs the rest of the hour.

“An easy, hands-off and nutritious way to feed a group for breakfast, brunch, lunch or dinner.”

Chop for the clock

Fine onion and pepper pieces soften in the egg mixture without adding a stovetop step.

Spread the fillings

An even layer prevents one corner from becoming all ham while another bakes as plain egg.

Read the middle

The center should no longer ripple like liquid and should register 160°F before the dish leaves the oven.

Each filling has a clear job, and the measured restraint keeps the bake sliceable without becoming heavy.

01

Eggs + milk

Eight eggs and one cup of milk form the tender, sliceable base that turns a skillet breakfast into a nine-serving bake.

Use the source’s whole-egg formula or its stated four-egg-plus-six-white alternative; do not change the rest of the ratios.
02

Ham + cheddar

Eight ounces of cooked ham provide savory weight while a modest half cup of cheddar melts through the custard.

Dice the ham small enough that every square gets some without creating heavy pockets on the bottom.
03

Onion + two peppers

Equal half-cup measures of onion, green pepper, and red pepper carry the classic Western-omelet identity.

Fine, even cuts matter because the vegetables go into the dish raw and soften only during baking.

Fifteen minutes that make the oven hands-off

Do the precise work before the eggs are mixed; once the dish is filled, the oven should own the next move.

Brunch clockCut whisk fill bake check rest

One hour, with the oven doing most of it

The card reports a one-hour total. The practical sequence leaves 45 minutes for baking and uses the upper limit only when the center needs it.

  1. 0:00

    Heat and grease

    Set the oven to 350°F and coat an 8-inch square baking dish all the way into the corners.

  2. 0:04

    Cut the fillings

    Dice the cooked ham and finely chop the onion and both bell peppers; shred the cheddar.

  3. 0:12

    Whisk the base

    Blend the eggs, milk, and seasoned salt, then stir in every filling.

  4. 0:15

    Fill the dish

    Pour, redistribute any clusters, and move the dish straight into the oven.

  5. 1:00

    Begin checking

    At 45 minutes, look for a set center and verify 160°F; continue only as needed, up to 1 hour.

  6. 1:05

    Rest and cut

    Pause for five minutes, then divide the square into a three-by-three grid and add chives.

Doneness cuesEven puffed still hot

Four signs the center is ready to cut

Color varies with the pan and oven; distribution, movement, and center temperature give the more useful evidence.

01

Fillings in every zone

Before baking, the ham and vegetables should be spread through the dish rather than banked at one edge.

02

Edges softly puffed

The perimeter rises a little and looks matte before the more protected center is ready.

03

No liquid wave

A gentle movement of the dish should not send uncooked egg rolling across the middle.

04

160°F at the center

Temperature settles the safety question; the short rest then settles the structure for slicing.

Keeping planBake cool cover reheat

Nine squares for brunch now or breakfast later

A baked omelet portions naturally. Prompt cooling and deliberate reheating keep that convenience safe.

Bake for the table

The source is already a crowd method: one dish replaces a sequence of individual omelets.

Cool promptly

Move leftovers into shallow covered containers and refrigerate within two hours of baking.

Keep 3 to 4 days

Use the FDA window for cooked egg dishes and keep the refrigerator at 40°F or below.

Reheat to 165°F

Warm only the portions you need until thoroughly hot; serve immediately after reheating.

Ingredients

Omelet

  • 8 large eggs, or 4 large eggs plus 6 egg whites
  • 1 cup milk
  • 1/2 teaspoon seasoned salt
  • 8 ounces cooked ham, diced
  • 1/2 cup shredded cheddar cheese
  • 1/2 cup finely chopped onion
  • 1/2 cup finely chopped green bell pepper
  • 1/2 cup finely chopped red bell pepper

To finish

  • Fresh chives, chopped, for garnish (optional)

Directions

  1. Heat the oven to 350°F (177°C). Grease an 8-inch square baking dish, reaching into the corners.
  2. Crack the eggs into a large bowl. Add the milk and seasoned salt, then whisk until the whites and yolks are fully blended.
  3. Stir in the diced cooked ham, shredded cheddar, finely chopped onion, green bell pepper, and red bell pepper until evenly distributed.
  4. Pour the mixture into the prepared baking dish. Use a spoon to spread any clustered ham and vegetables into an even layer.
  5. Bake for 45 minutes to 1 hour, until the center is set rather than liquid and an instant-read thermometer checked in the center reaches 160°F (71°C).
  6. Let the omelet stand for 5 minutes for cleaner squares. Cut into 9 portions and finish with chopped chives, if desired.
