Instructions
- Preheat the Oven:
- Set your oven to 350 degrees Fahrenheit and grease a nine by thirteen inch baking dish generously. This prevents sticking and helps develop those irresistible golden edges.
- Mix the Ingredients:
- In a large bowl combine cooked rice, cubed ham, frozen peas, cream of chicken soup, sour cream, two cups of shredded cheddar cheese, most of the salt, pepper, onion powder, garlic powder, and hot sauce. Stir thoroughly until everything is evenly coated and no pockets of creamy soup remain.
- Layer the Casserole:
- Transfer the mixture into your prepared baking dish. Spread it evenly using a spatula. Sprinkle the last cup of shredded cheddar cheese evenly over the top to form a cheesy crust.
- Bake Until Bubbly:
- Place the casserole on the center rack of your oven and bake uncovered for about thirty minutes. Look for bubbling around the edges and a golden, melted cheese topping.
- Cool Slightly and Serve:
- Remove from the oven and let the casserole sit for five minutes. This resting time helps the dish set so that slices hold together neatly when served.

I always savor that first bite when the melted cheddar melds perfectly with the savory ham and the sweetness of the peas. One of my favorite memories is my youngest helping sprinkle the cheese on top and proudly declaring this dinner the best ever.
Storage Tips
Store leftovers covered tightly in the fridge for up to four days. Reheat single servings in the microwave with a splash of milk for creaminess. For longer storage, cool completely, wrap tightly, and freeze for up to three months. Reheat from frozen in the oven or microwave until heated through.
Ingredient Substitutions
Try turkey or cooked chicken in place of ham if you want a different protein. Cream of mushroom or celery soup works well instead of cream of chicken for a new flavor angle. For glutenfree needs, use certified glutenfree canned soups and verify your other ingredients.
Serving Suggestions
Pair this casserole with a crisp green salad or steamed broccoli for a fresh contrast. Garlic bread or warm dinner rolls make excellent sides for mopping up any extra cheesy sauce.

This cheesy ham and pea casserole is an easy, crowd pleasing weeknight meal that makes the most of leftover ham. It reheats well and freezes nicely for simple make ahead dinners.
