Breakfast Casserole Bake

Having grown up on a farm and being so closely connected to the challenging manual labor that goes into every item in the grocery store I appreciate a good meal.

I especially appreciate a recipe like this ham, egg and cheese bake and Cowboy Breakfast Skillet where I’ve had the opportunity to know farmers who are a part of every ingredient in this meal. The hands-on time commitment to grow the food is significant, but the time spent on improving what they do is equally impressive.

When we serve recipes with pork I know that we’re helping to support not only our farming family, but more than 3,500 family farms in Ohio that raise enough food to feed about 25 million people. So when you buy pork at the grocery store you are supporting Ohio farm families!

I’m also learning more about how foods make my body feel. When I take the time to notice, there’s a big difference in my hunger level when I eat more protein. I feel full longer and feel more satisfied overall when increasing protein consumption.

Every 3 ounces of pork is packed full of 22 – 24 grams of protein which helps me accomplish my goals of smarter eating. Whether it’s our Kielbasa and Sauerkraut or our Pork Chop Casserole I know eating protein is important!

Baked Ham & Cheese Omelet Recipe

Ingredients Needed:

Diced ham – can be purchased already diced OR you can finely dice leftover ham for this meal. Pork is a great source of protein which is important in helping you feel full longer.
Eggs – use large or extra large eggs, this is the predominant flavor in the dish.
Bisquick – thickens the mix, adds flavor and makes the casserole more filling.
Milk – helps the crust brown on top, adds calcium and protein to the meal.
Dry mustard & parsley flakes – add a little dimension and depth to the flavors.
Kosher salt & freshly ground pepper – each have a bit coarser grind and slightly larger particles that enhance the flavor of the dish and can be used based on personal preference.
Sliced mushrooms – using a jar of drained mushrooms is convenient because they have already been sliced and cooked. Fresh mushrooms can be used, but should be chopped up more finely so they can tenderize while baking in the egg casserole.
Tomatoes – add color and texture to the dish while contributing more nutrients as well.
Green onions – are the most mild onion, add more fiber and a bit more dimension to the flavor profile. A couple tablespoons of any onion may be finely chopped and stirred in with the scrambled eggs.
Sharp cheddar cheese – add some fat to the dish which creates more flavor. Sharp cheese provides more contrasting flavors and the melty look and sensation that many people enjoy!

We also love using this baking mix in our Cheddar Bay Biscuits with Bisquick.

Should An Egg Casserole Be Covered While Baking?

Baking an egg casserole uncovered will allow it to become golden brown over top around the edges.

If the casserole is really thick or your oven gets too hot, cover the casserole with foil for the first half of the baking time. This can help play it safe and prevent burning if there’s a concern.

How to Make Baked Eggs with Ham and Cheese

In a medium mixing bowl scramble eggs. A fork is usually easiest for me to use.

Then mix in salt, pepper, dry mustard and parsley flakes.

Add Bisquick.

Mix aggressively until the egg mixture is smooth and no clumps of flour remain

The rest is super easy. Add uniform pieces of ham and stir.

I like to purchase diced ham, but if another kind of ham is used, just make sure to cut small and evenly sized pieces.

Add tomatoes and mushrooms and stir again.

Then bake uncovered in a 350°F for 35 to 45 minutes. When finished a knife inserted in the center should come out clean.

Recipe Tips & Tricks

If using leftover ham make sure to start with a quality juicy product. Dried out ham will not enhance and help create the best flavors in this recipe.
Bisquick can be replaced with 1 to 1 1/2 slices of cubed toast.
Picky eaters may prefer a plain casserole without the vegetables. This is a very easy change to make.
Using an 8×8′ pan makes nice thick pieces. For more of a thinner, omelet feel and a quicker baking time use a larger 9×13′ pan.
Some people love whisking eggs to scramble them, but I find a fork is the most efficient tool I have to get the job done.
A convection oven will bake the eggs a little more quickly than a traditional conventional oven.
