Ham and Cheese Hash Brown Casserole

There’s something wonderfully comforting about a hot, cheesy hash brown casserole. Tender potatoes, savory ham, melted cheese, and a creamy sauce come together in one bubbling dish that feels just right for a relaxed breakfast or brunch.

This casserole is especially handy when you’re feeding a group. It can be assembled ahead of time, baked when you’re ready, and served straight from the dish. The edges turn golden and cheesy while the center stays soft and creamy.

It’s also a great way to use leftover ham after a holiday meal. Add a simple green salad or some fresh fruit on the side, and you have an easy meal without much extra work.

Getting Those Crispy, Cheesy Edges

The key to a good hash brown casserole is getting the potatoes cooked through without letting the whole dish become watery. If you’re using frozen shredded hash browns, thaw them first and gently squeeze out excess moisture.

For the nicest texture, spread the mixture evenly in the baking dish rather than packing it down too firmly. That gives the potatoes room to cook while the top develops those golden, browned edges.

Ingredients You’ll Need

Here’s everything you need to make this hearty casserole:

• Frozen shredded hash browns, thawed
• Cooked ham, diced
• Cheddar cheese, shredded
• Cream of chicken soup
• Sour cream
• Milk
• Yellow onion, finely diced
• Garlic powder
• Salt
• Black pepper
• Butter

How To Make Ham And Cheese Hash Brown Casserole

1. Step 1: Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray.

2. Step 2: In a large bowl, whisk together the cream of chicken soup, sour cream, milk, garlic powder, salt, and black pepper until smooth. Stir in the diced onion.

   

3. Step 3: Add the thawed hash browns, diced ham, and about 1½ cups of the shredded cheddar. Gently fold everything together until the potatoes are evenly coated. Try not to mash or overmix the hash browns.

4. Step 4: Transfer the mixture to the prepared baking dish and spread it into an even layer. Sprinkle the remaining cheddar over the top and dot with a little butter if desired.

5. Step 5: Bake uncovered for 45–55 minutes, until the casserole is hot and bubbling around the edges and the cheese is melted and lightly browned. If the top starts browning too quickly, loosely cover it with foil for the remainder of the baking time.

6. Step 6: Let the casserole rest for about 5–10 minutes before serving. This gives the creamy filling a chance to settle and makes it easier to scoop without the casserole falling apart.

   

FAQs

Can I Use Fresh Potatoes Instead Of Frozen Hash Browns?

Yes. Shred about 4–5 medium russet potatoes and rinse them well to remove excess starch. Dry them thoroughly with a clean kitchen towel before adding them to the mixture.

Do I Need To Thaw The Hash Browns?

It’s recommended. Thawed hash browns cook more evenly and release less excess water into the casserole. If you use them frozen, you may need to add extra baking time.

Can I Make This Casserole Ahead Of Time?

Absolutely. Assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours. Let it sit at room temperature for about 15–20 minutes before baking, and expect to add a little extra time if it’s still quite cold.

What Kind Of Ham Should I Use?

Diced leftover baked ham works beautifully, but sliced deli ham or a thick-cut ham steak can also be used. Just cut it into small, bite-sized pieces.

Can I Use A Different Cheese?

Yes. Cheddar is a classic choice, but Monterey Jack, Colby, Swiss, or a cheddar-Jack blend all melt nicely.

Why Is My Casserole Watery?

The most common reason is excess moisture from the potatoes. Make sure frozen hash browns are thawed and well drained before mixing them into the casserole.

Recipe Variations

Ham And Broccoli

Stir in 1–2 cups of cooked, chopped broccoli for extra vegetables. Make sure the broccoli is well drained so it doesn’t add too much moisture.

Ham And Pepper

Add a diced bell pepper with the onion for a little sweetness and color. Red or green peppers both work well.

Extra Cheesy

For a richer casserole, increase the cheese slightly or combine cheddar with Monterey Jack. A little Parmesan sprinkled over the top also adds a nicely browned finish.

Breakfast-Style

Add a few beaten eggs to the mixture for a more substantial breakfast casserole. Serve it with fresh fruit and toast for a complete brunch.

Turkey And Cheese

Leftover cooked turkey can be substituted for the ham, making this an easy option after Thanksgiving or another holiday meal.

Storage And Reheating

Refrigerate leftovers in an airtight container for up to 3–4 days. Reheat individual portions in the microwave, or warm larger amounts in a 350°F oven until heated through. The casserole can also be frozen, preferably in individual portions, for up to 2 months; thaw overnight in the refrigerator before reheating.

What To Serve With Ham And Cheese Hash Brown Casserole

This casserole is hearty enough to stand on its own, but it’s especially good alongside fresh fruit, sliced melon, or a simple green salad to lighten things up. For breakfast or brunch, serve it with scrambled eggs, fresh berries, toast, or a glass of orange juice; for lunch or dinner, roasted vegetables make an easy side.

If you’re serving it for a crowd, let it rest briefly after coming out of the oven so the slices or scoops hold together nicely. The combination of creamy potatoes, salty ham, and crisp golden cheese is best while it’s still warm.

This Ham and Cheese Hash Brown Casserole is a creamy, cheesy comfort food favorite made with crispy hash browns, savory ham, and plenty of melted cheese. It’s easy to prepare, hearty, and perfect for breakfast, brunch, or a cozy family dinner.
