Frequently Asked Questions
Can I use frozen hash browns instead of fresh potatoes?
Absolutely. In fact, many classic versions of this casserole use a 30-ounce bag of frozen shredded or cubed hash browns (thawed). It’s a huge time-saver. Make sure they are fully thawed and any excess moisture is drained before mixing. You may want to reduce the baking time by about 10 minutes, as frozen potatoes are par-cooked and soften faster. Check for doneness by ensuring the center is hot and bubbly.
What if I don’t have cream of chicken soup?
You can substitute cream of celery, cream of mushroom, or cream of onion soup. For a vegetarian version, cream of celery or mushroom are perfect. You can also make a quick homemade substitute: melt 2 tablespoons of butter, whisk in 2 tablespoons of flour, and cook for 1 minute. Gradually whisk in 1 cup of chicken or vegetable broth and ½ cup of milk, cooking until thickened. Season with salt, pepper, and a pinch of poultry seasoning. Let it cool slightly before mixing with the sour cream.
Can I use a different topping besides Ritz crackers?
Yes! Buttered panko breadcrumbs, crushed cornflakes, crushed potato chips, or French fried onions all make fantastic crunchy toppings. The key is to toss them with melted butter so they brown and crisp in the oven. Each topping brings its own unique flavor and texture, so feel free to experiment with what you have on hand.
My casserole turned out a little runny—what went wrong?
This can happen if the potatoes released a lot of moisture, if the frozen hash browns weren’t drained, or if the sour cream or soup was very thin. To prevent this, make sure to drain any excess liquid from frozen potatoes or corn. Baking the casserole until it’s fully bubbly and set in the center also helps the sauce thicken. If it’s still runny after baking, let it rest for 10–15 minutes; it will thicken as it cools slightly.
Is this dish gluten-free?
It can be. Use a gluten-free cream of chicken soup (or make a gluten-free version), and for the topping, use crushed gluten-free crackers or gluten-free panko breadcrumbs tossed with butter. All other ingredients are naturally gluten-free. Always check labels on packaged ingredients to be sure. If serving to someone with celiac disease, confirm that every component is certified gluten-free.

Rest Time:
5–10 minutes
Total Time:
1 hour 15 minutes
Servings:
8–10
Ingredients
- 4 cups diced potatoes (½-inch cubes), or 1 (30 oz) bag frozen shredded or cubed hash browns, thawed
- 1 can (15 oz) sweet corn, drained (or 1½ cups frozen corn, thawed)
- 1 cup full-fat sour cream
- 1 can (10.5 oz) condensed cream of chicken soup, undiluted
- 2 cups shredded sharp cheddar cheese, divided
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon black pepper
- Salt to taste (be light-handed; soup and cheese are salty)
For the Topping:
- 1 sleeve (about 30 crackers) Ritz crackers, crushed into coarse crumbs
- 4 tablespoons unsalted butter, melted
Instructions
- Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.
- In a very large bowl, combine sour cream, undiluted cream of chicken soup, garlic powder, onion powder, pepper, and a pinch of salt. Stir until smooth. Mix in 1½ cups of the cheddar cheese.
- Fold in the diced potatoes and drained corn until everything is thoroughly coated in the creamy sauce. Transfer to the prepared baking dish and spread evenly. Sprinkle the remaining ½ cup cheddar on top.
- Make the topping: Combine the crushed Ritz crackers and melted butter. Sprinkle evenly over the casserole.
- Bake for 45–55 minutes, until the edges are bubbly, the center is hot and set, and the topping is golden brown. If the top browns too quickly, tent loosely with foil.
- Rest for 5–10 minutes before serving. Garnish with fresh parsley or chives if desired. Serve hot.
Notes
- For a time-saver, use thawed frozen hash browns instead of fresh potatoes; drain any excess liquid. Baking time may be slightly shorter—check for doneness at 40 minutes.
- For a vegetarian version, use cream of celery or mushroom soup. For a gluten-free version, use gluten-free soup and crushed gluten-free crackers or panko for the topping.
- Leftovers keep in the refrigerator for up to 4 days. Reheat in the oven or air fryer to re-crisp the topping.
- Customize with add-ins like cooked bacon, diced ham, green chiles, or steamed broccoli for a main-dish casserole.
