How to Make Loaded Cheesy Ham and Hash Brown Casserole

Step 1: Preheat and Prepare the Dish

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with non-stick spray or butter to prevent sticking and ensure a golden crust.

Step 2: Mix the Ingredients

In a large bowl, combine:

• Thawed hash browns

• Diced ham

• Shredded cheddar and mozzarella

• Sour cream

• Cream of mushroom soup

• Milk

• Finely chopped onion

• Melted butter

• Garlic powder, salt, and pepper

Mix until everything is well combined and evenly coated.

Step 3: Assemble the Casserole

Pour the mixture into your prepared baking dish and spread it evenly. If using bacon bits, sprinkle them generously over the top for extra texture and flavor.

Step 4: Bake to Perfection

Cover the dish with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 15–20 minutes, or until the top is golden brown and bubbling around the edges.

Step 5: Cool and Serve

Let the casserole cool for 5–10 minutes before serving. Sprinkle with fresh parsley for a pop of color and added freshness.

Recipe Tips & Shortcuts

• No ham? Use rotisserie chicken, leftover turkey, or cooked sausage instead.

• Add veggies like bell peppers, mushrooms, or spinach to bulk it up and add color.

• Cream of chicken soup can be substituted for cream of mushroom if preferred.

• Make it ahead: Assemble everything the night before and store covered in the fridge. Just pop it in the oven when you’re ready!

• Low-fat option: Use low-fat sour cream, reduced-fat cheese, and skim milk to lighten it up slightly without sacrificing flavor.

Storage and Reheating Tips

This casserole is a dream for leftovers. Here’s how to store it:

• Refrigerator: Store tightly covered or in an airtight container for up to 4 days.

• Freezer: Wrap portions tightly in plastic wrap and foil or use freezer-safe containers. Freeze for up to 3 months.

• To Reheat: Microwave individual servings or reheat in the oven at 325°F (160°C) until warmed through. If frozen, thaw overnight in the fridge first for best results.

What to Serve With It

This loaded casserole is practically a meal on its own, but here are a few tasty pairings:

Frequently Asked Questions

Can I use fresh potatoes instead of frozen hash browns?

Yes, but you’ll need to shred them first and soak them in water to remove excess starch. Then pat them dry thoroughly to avoid sogginess.

Can I make this casserole without soup?

You can substitute the soup with a homemade white sauce using butter, flour, milk, and seasonings if you prefer a from-scratch version.

Can I use different cheese?

Absolutely. Try Monterey Jack, pepper jack, Gruyère, or Colby for a fun twist. Just make sure to keep the cheese to about 2 cups total.

Is this casserole gluten-free?

Most ingredients are naturally gluten-free, but check that the cream of mushroom soup is certified gluten-free or use a homemade substitute.
