Ingredients You’ll Need
Each ingredient in this French Onion Potato Casserole Recipe plays a crucial role in building layers of flavor, texture, and warmth. From the creamy base to the crispy topping, these simple components come together beautifully to make this dish utterly irresistible.
- Frozen shredded hash browns: The starchy foundation that offers a tender yet slightly crisp potato texture.
- Unsalted cream of chicken soup: Adds a luscious creaminess and subtle savory depth without overpowering other flavors.
- Refrigerated sour cream based French onion dip: Brings that unmistakable French onion flavor, creamy tang, and richness that make this casserole stand out.
- Shredded cheddar cheese: Melts perfectly to create gooey deliciousness, adding sharpness and extra comfort.

How to Make French Onion Potato Casserole Recipe
Step 1: Preheat and Prepare Your Pan
Start by preheating your oven to 350ºF and lightly spraying a 9×13-inch baking dish with cooking spray. This ensures your casserole won’t stick and makes cleanup a breeze. Trust me, a good base sets you up for success!
Step 2: Mix the Creamy Potato Filling
In a large bowl, combine the frozen shredded hash browns with the cream of chicken soup, the French onion dip, and shredded cheddar cheese. Mix everything gently but thoroughly so every potato strand is coated in that silky, cheesy goodness. This base layer is where all the luscious flavors marry together beautifully.
Step 3: Transfer to Baking Dish
Pour your creamy potato mixture into the prepared pan and spread it out evenly. This even layer will bake up smooth and soft inside, providing just the right bite in every spoonful.
Step 4: Prepare the Crispy Topping
In a small bowl, combine the crushed corn flakes with the melted butter. The butter acts like glue, helping the corn flakes brown into a perfectly crunchy topping as the casserole bakes. Sprinkle this mixture evenly over the potato layer to guarantee a sensational textural contrast.
Step 5: Bake Until Bubbling and Golden
Place your casserole in the preheated oven and bake uncovered for 1 hour. During this time, the flavors deepen and meld, the cheese melts, and the topping becomes a golden, crispy masterpiece. Let it rest a few minutes once out of the oven before serving to help it set up nicely.
How to Serve French Onion Potato Casserole Recipe
Garnishes
A sprinkle of freshly chopped green onions or parsley adds a fresh, vibrant pop of color and a slight bite that complements the rich casserole. You might also add a few crispy fried onions for an extra layer of that classic French onion crunch.
Side Dishes
This casserole pairs wonderfully with lighter, crisp side salads or steamed seasonal veggies to balance out the richness. A simple Caesar salad or some roasted asparagus can turn your meal into a perfectly balanced feast.
Creative Ways to Present
For a festive twist, serve the casserole in individual ramekins for personal portions. You might also top it with dollops of sour cream or a drizzle of caramelized onion jam to amplify that famed French onion flavor.
Make Ahead and Storage
Storing Leftovers
Any leftovers can be covered tightly and stored in the refrigerator for up to 3 days. The casserole flavors actually deepen as it rests, making leftovers taste just as good if not better the next day.
Freezing
This French Onion Potato Casserole Recipe freezes beautifully. Assemble it fully, cover with foil, then freeze for up to 2 months. Thaw overnight in the refrigerator before baking as usual.
Reheating
Reheat individual portions in the microwave for a quick fix, or cover the entire casserole and warm it in a 350ºF oven until heated through to keep the topping crisp and delicious.
FAQs
Can I use fresh potatoes instead of frozen hash browns?
You can, but frozen shredded hash browns are preferred for ease and consistent texture. If using fresh, make sure to shred, rinse, and dry them well to avoid excess moisture.
Is there a vegetarian version of this casserole?
Absolutely! Simply swap the cream of chicken soup for a cream of mushroom or vegetable soup and use a vegetarian French onion dip to keep all the flavor without the meat ingredients.
Can I make this casserole dairy-free?
Yes, with some ingredient swaps: use dairy-free sour cream-based French onion dip, a dairy-free cheddar-style cheese, and a suitable dairy-free cream soup. The delicious taste remains with these alternatives.
What is the best way to crush corn flakes for the topping?
Place the corn flakes in a sturdy plastic bag and gently crush them with a rolling pin or the bottom of a glass until they are in fine, crumbly pieces for an even, crispy crust.
Can I add extra vegetables to this casserole?
Definitely! Diced sautéed mushrooms, caramelized onions, or even chopped spinach can add a wonderful twist and extra nutrition without overpowering the classic flavors.
