How to Make Cheesy Ham and Potato Casserole
First, gather all the ingredients. Cube the ham, grate the cheese, chop the onion, green pepper, and parsley.
Rinse, peel, and cut up the russet potatoes into small pieces for faster cooking. Place in cold, salted water.
Bring the covered pot to a boil. Simmer for 10 to 12 minutes or until fork tender. Drain, then add back to the pot.
Saute the red onion and green bell pepper until soft in a small skillet. Add to the cooked potatoes.
Melt the butter and add the flour one tablespoon at a time until the desired consistency is reached. Cook the flour for 3 minutes, whisking constantly.
At moderate heat, gradually add the milk, whisking constantly to achieve a smooth sauce. Keep whisking until the sauce thickens, about 8 to 10 minutes. Lower the heat and gradually add the cheese.
Whisk until the sauce is smooth and all the cheese has melted.
Remove the cheese sauce from the heat. Pour over the potatoes, corn, ham, onions, peppers, and spices.
Gently stir to combine.
Pour into a casserole dish. (If you want to make it ahead, you’ll cover the dish and put it in the fridge at this step.) When ready to serve, cook for 30 minutes at 350 F or 20 minutes at 400 F if you’re in a hurry. Garnish with freshly grated Parmesan cheese and fresh parsley. Allow to set for a few minutes, and serve warm.
- Peel and dice the potato in small even chunks to speed up the cooking.
- Whole milk works better than 2% for the cheese sauce.
- Use freshly grated cheese, not pre-grated.
- Add an extra tablespoon of flour to the roux for a thicker cheese sauce.
- As the potatoes bake, they will absorb some of the cheese sauce.
- Allow to set for a few minutes before serving.
- Cooking for a crowd? It’s easy to double.
- Make Ahead Tip: make the day before then just before serving, bake for 30 minutes and garnish.
