The Complete Cheesy Potato Casserole Recipe
This recipe serves 6‑8 people. It fits a 9×13 inch baking dish and can easily be doubled.
Ingredients:
6‑7 medium russet potatoes (about 2.5 lbs / 1.1 kg), peeled and thinly sliced (⅛‑inch thick)
1 can (10.5 oz) condensed cream of chicken soup (do not add water)
2 cups (8 oz / 225g) shredded sharp cheddar cheese
Salt and black pepper, to taste
Optional Add‑Ins and Toppings:
4 slices cooked bacon, crumbled
½ cup diced onion
½ cup sour cream (for extra creaminess)
¼ cup grated Parmesan cheese (to mix with cheddar)
½ cup crushed cornflakes or panko breadcrumbs mixed with 2 tablespoons melted butter (for a crunchy topping)
Fresh parsley or chives for garnish
Equipment:
- 9×13 inch baking dish
- Non‑stick spray or butter
- Aluminum foil
- Cutting board and knife (or mandoline for even slices)
Step‑by‑Step Instructions
Step 1 – Preheat and Prepare the Dish
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with non‑stick spray or butter.
Step 2 – Slice the Potatoes
Peel the russet potatoes and slice them thinly, about ⅛‑inch thick. A mandoline slicer makes quick work of this and ensures even slices. Uniform slices are key to even cooking. Do not rinse the sliced potatoes – you want the starch to help thicken the casserole.
Step 3 – Layer the Potatoes
Arrange the sliced potatoes evenly in the prepared baking dish. Season lightly with salt and black pepper. Remember that the soup and cheese already contain salt, so go easy.
Step 4 – Add the Soup and Cheese
Spread the condensed cream of chicken soup over the potatoes. Use a spatula or the back of a spoon to spread it evenly. Do not add water – the soup will thin out as it bakes. Sprinkle the shredded cheddar cheese generously over the top. If you are adding onion or bacon, scatter them over the potatoes before adding the cheese.
Step 5 – Cover and Bake
Cover the baking dish tightly with aluminum foil. Bake at 375°F for 50‑60 minutes, until the potatoes are nearly fork‑tender.
Step 6 – Uncover and Finish Baking
Remove the foil. If you are adding a crunchy topping (like crushed cornflakes or breadcrumbs), sprinkle it over the cheese now. Return the dish to the oven, uncovered, and bake for an additional 15‑20 minutes, until the cheese is golden and bubbly and the potatoes are completely tender (a knife should slide through with no resistance).
Step 7 – Rest and Serve
Let the casserole rest for 10 minutes before serving. This allows the potatoes to set and makes serving easier. Garnish with fresh parsley or chives if desired. Serve hot as a side dish or a vegetarian main.
Pro Tips for the Best Cheesy Potato Casserole
Follow these expert tips for perfect creamy potato casserole every time:
Slice potatoes evenly – Uneven slices will result in some potatoes being undercooked while others turn to mush. Use a mandoline or a sharp knife.
Do not rinse the sliced potatoes – The natural starch helps thicken the casserole and creates a creamier texture.
Use sharp cheddar for the best flavor – Sharp or extra‑sharp cheddar stands up to the creamy soup. Mild cheddar can get lost.
Do not add water to the soup – The condensed soup is meant to be used as is. The potatoes release moisture as they bake, creating a perfect sauce.
Cover tightly with foil – This traps steam and ensures the potatoes cook through without drying out.
Test for doneness – Pierce the thickest potato slice with a fork or knife. It should slide in easily. If not, bake covered for another 10 minutes.
Let it rest before serving – Resting allows the casserole to set, making it easier to scoop and serve.
Delicious Variations (Same Easy Base)
Once you master the classic cheesy potato casserole, try these fun twists. These potato casserole variations will keep your dinners exciting.
1. Bacon Cheddar Potato Casserole
Add ½ cup of cooked, crumbled bacon to the layers. Sprinkle extra bacon on top before the final bake. The smoky, salty bacon is a perfect match. This is a bacon cheese potato casserole that is pure comfort.
2. French Onion Potato Casserole
Add 1 cup of caramelized onions to the potato layers. Use Gruyère or Swiss cheese instead of cheddar. The sweet, savory onions add incredible depth. This is a French onion potato bake.
3. Creamy Sour Cream Potato Casserole
Mix ½ cup of sour cream into the condensed soup before spreading. The sour cream adds tang and extra creaminess. This is a sour cream potato casserole that is extra decadent.
Add 1 cup of diced cooked ham along with the potatoes. Use a mix of cheddar and Swiss cheese. This is a great way to use leftover ham. This is a ham and potato casserole perfect for post‑Easter.
5. Broccoli Cheese Potato Casserole
Add 2 cups of steamed broccoli florets to the potato layers. The broccoli adds color and nutrients. This is a broccoli potato casserole that is a complete meal.
Replace the potatoes with 4 cups of thinly sliced turnips or cauliflower. Reduce baking time by 10‑15 minutes (cauliflower cooks faster). This keto potato casserole is low in carbs.
7. Gluten‑Free Cheesy Potato Casserole
Ensure your condensed cream of chicken soup is gluten‑free (many brands are). The rest of the ingredients are naturally gluten‑free. This gluten free potato bake is safe for celiacs.
Before the final uncovered bake, sprinkle ½ cup of crushed cornflakes or panko breadcrumbs mixed with 2 tablespoons of melted butter over the cheese. The extra crunch is wonderful.
