What Ingredients are in Creamy Cheesy Au Gratin Potatoes?
I’m a firm believer that the best recipes often have the simplest ingredients—things you probably already have in your kitchen right now. These creamy au gratin potatoes are the perfect example of comfort food magic that happens when basic ingredients come together. The combination creates this incredible, rich, cheesy casserole that somehow manages to be both homey and elegant at the same time.
- 7 large potatoes
- 4 tablespoons butter or margarine
- 1 (10½ ounce) can cream of chicken soup
- 1½ cups grated cheddar cheese
- 1½ cups sour cream
- 1 tablespoon minced onion
- Salt and pepper to taste
When shopping for this recipe, quality really does matter for a few key ingredients. Try to find russet potatoes if possible—they have that perfect starchy quality that works beautifully in au gratin dishes.
And while pre-shredded cheese is convenient, freshly grated cheddar will melt more smoothly into that dreamy sauce. Sharp cheddar adds the best flavor, but mild works too if you prefer a more subtle cheese taste.
As for the sour cream, full-fat creates the creamiest result, though reduced-fat will work in a pinch. The beauty of this recipe is its flexibility while still delivering that classic, comforting au gratin experience.
How to Make these Creamy Cheesy Au Gratin Potatoes

Making these creamy au gratin potatoes couldn’t be more straightforward, and the results are absolutely worth it. Start by cooking 7 large potatoes with their skins on until they’re tender. This helps maintain their structure while cooking.
Once they’ve cooled completely (patience is key here), peel them and either cut them into small cubes or grate them—whichever texture you prefer. The smaller pieces help the sauce penetrate every bite, which is exactly what we want.
Now for the creamy, cheesy goodness. In a bowl, combine 4 tablespoons of butter or margarine, a 10½ ounce can of cream of chicken soup, 1½ cups of grated cheddar cheese, and 1½ cups of sour cream.
Don’t forget to add 1 tablespoon of minced onion for that subtle flavor that makes all the difference. Season with salt and pepper to taste—potatoes love salt, trust me on this one.
Pour this heavenly mixture over your prepared potatoes in a 9×13-inch baking dish, making sure every potato piece gets coated. For even more exceptional results, consider using a premium Dutch oven for more even heat distribution and superior cooking performance. Cover the dish and bake at 325°F for about 30-45 minutes.
The result? Potatoes that are creamy on the inside, slightly golden on top, and utterly irresistible. Comfort food doesn’t get much better than this.
Creamy Cheesy Au Gratin Potatoes Substitutions and Variations
While this classic recipe is absolutely delicious as written, the beauty of au gratin potatoes lies in their versatility. I can’t resist suggesting a few delicious swaps that might suit your pantry or preferences.
Try substituting Gruyère or fontina for the cheddar if you’re craving something more complex, or mix in smoked gouda for a wonderful depth. Don’t have sour cream? Greek yogurt works beautifully. Vegetarians can easily switch to cream of mushroom soup instead of chicken.
For exciting variations, I’d recommend adding crispy bacon bits, fresh herbs like thyme or rosemary, or even thinly sliced leeks instead of minced onion.
What to Serve with Creamy Cheesy Au Gratin Potatoes
These indulgent, golden-topped creamy au gratin potatoes deserve perfect companions to create a memorable meal.
I’m always looking for proteins that can stand up to the richness without competing for attention. A simple roasted chicken with herbs, glazed ham, or medium-rare steak all provide beautiful contrast to those creamy, cheesy layers.
For balance, I’d add something green and slightly acidic—perhaps a vinaigrette-dressed arugula salad or roasted Brussels sprouts with a touch of balsamic. The slight bitterness cuts through all that dairy beautifully.
Don’t forget a crisp white wine to refresh your palate between bites!
Final Thoughts
At the heart of every great meal is a dish that brings comfort and connection to the table, and I’m convinced these creamy au gratin potatoes do exactly that.
There’s something magical about the way the tender potato slices meld with rich, melted cheddar and that velvety sour cream sauce, creating little pockets of flavor in every bite.
Whether you’re hosting a holiday dinner or simply craving something hearty on a chilly evening, this classic side dish never disappoints.
The beauty lies in its simplicity—familiar ingredients transforming into something extraordinary with just a bit of time in the oven.
