I have always loved hominy, and this hominy au gratin casserole is no exception. It’s creamy, cheesy, and flavorful.

What is hominy?

Hominy is corn. To make hominy, field corn or maize is dried. It is then treated by soaking and cooking the mature, hard grain (versus fresh, soft corn) in a dilute solution of either lye, slaked lime, which is calcium hydroxide, or wood ash. This process is termed nixtamalization. The soaked maize loosens the hulls from the kernels and softens the kernels themselves. The process causes the kernels to double in size. It is then either left whole for hominy or ground into masa, used for tortillas and tamales, among other things.

I made a béchamel base for this casserole and added cheddar cheese. Béchamel is a “white sauce” made with milk, butter, and flour.

This recipe is very similar to macaroni and cheese. Although the hominy provides a different texture than pasta, it has many of the same flavors.

Most noteworthy, Béchamel sauce is the mother, or base, sauce of many other classic sauces with the addition of a few more ingredients, including:

  • Mornay sauce, which is a cheese sauce
  • Nantua sauce is a crayfish, butter, and cream
  • Crème sauce uses heavy cream
  • Cheddar cheese sauce contains cheddar cheese, dry mustard, and Worcestershire sauce.

I’ve made this recipe for years and recently decided to top it with bacon. Consequently, bacon does make everything better. I didn’t think it was possible this casserole was better, but bacon does it. Of course, you can omit the bacon if you so desire. I cooked and crumbled bacon which does take a few minutes to cook. However, for an easy bacon addition, you may want to use bacon bits, which you put on salads. They are good and save a lot of cooking time.

Another suggestion, I don’t recommend using pre-shredded cheese, it is coated with cornstarch to prevent it from sticking together.

Also, to make this a main dish meal, simply stir in 1 cup of cooked, shredded, or cubed chicken.

    Wow! So delicious. Very surprised, creamy with lots of flavor. The hominy makes it taste like your eating a tamale casserole. This is a keeper recipe, a little different spin on meat and potatoes too.

    1. If it were 350 Celsius the equivalent would be 662 degrees Fahrenheit. I seriously doubt that anyone would cook anything at that temperature or would have an oven that could reach that temperature. So to answer your question, I would ASSUME that 350F is the correct assumption.
