- Heavy cream (1 cup): Ensures the dish is luxuriously smooth and creamy.
- Milk (½ cup): Lightens the cream just enough for perfect consistency.

How to Make French Onion Potato Bake: Creamy, Cheesy Comfort Food Recipe
Step 1: Prepare Your Oven and Dish
Start by preheating your oven to 375°F (190°C) so it’s ready to go when your bake is assembled. Lightly grease a 9-by-13-inch baking dish; this ensures the potatoes won’t stick and the edges crisp up just right.
Step 2: Caramelize the Onions
In a large skillet, gently melt the butter with olive oil over low heat. Add the thinly sliced onions and patiently cook them for 25 to 30 minutes until they turn a rich, golden brown and become sweet and soft. Stir occasionally—this slow cooking is where much of the magic happens! Toss in the minced garlic and cook for an extra minute to release its fragrant goodness.
Step 3: Mix the Creamy Cheese Sauce
In a mixing bowl, whisk together the heavy cream, milk, salt, pepper, and half of your grated Gruyère and Parmesan cheeses. This creamy mixture is what pulls everything together, coating the potatoes and onions with a velvety, cheesy blanket.
Step 4: Layer the Potatoes and Onions
Begin layering by spreading half of your thin potato slices evenly across the bottom of your prepared baking dish. Next, add half of the caramelized onion and garlic mixture over the potatoes. Pour half of the cream and cheese blend on top. Repeat the layering process with the remaining potatoes, onions, and cream mixture to build up the flavors beautifully.
Step 5: Top and Bake
Sprinkle the remaining Gruyère and Parmesan cheese evenly over the top layer. Cover your dish tightly with foil to prevent the cheese from browning too quickly. Bake for 40 minutes, then remove the foil and bake for another 15 to 20 minutes so the top becomes golden brown, bubbly, and irresistible.
Step 6: Rest and Garnish
Allow your French Onion Potato Bake to rest for about 10 minutes once out of the oven. This helps it settle and makes serving easier. For an aromatic and colorful touch, sprinkle fresh thyme leaves over the top before serving.

Garnishes
A sprinkle of fresh thyme or chopped chives not only makes the dish visually stunning but adds a refreshing herbal note that cuts through the richness beautifully.
Side Dishes
This bake pairs wonderfully with a crisp green salad tossed in a light vinaigrette to balance the creaminess. For heartier meals, roasted vegetables or a simple protein like grilled chicken or steak complement it perfectly.
Creative Ways to Present
Try serving the French Onion Potato Bake in individual ramekins for a charming presentation at dinner parties. Alternatively, add a few crumbled cooked bacon strips on top before the final bake for a smoky twist that guests will adore.
Make Ahead and Storage
Storing Leftovers
Place any leftovers in an airtight container and store in the refrigerator for up to 3 days. The flavors deepen overnight, making for a fantastic next-day meal.
Freezing
This dish freezes well—transfer cooled leftovers into a freezer-safe container and freeze for up to 2 months. Thaw in the refrigerator overnight before reheating to preserve its creamy texture.
Reheating
To reheat, cover the dish with foil and warm it in a 350°F (175°C) oven for about 20-30 minutes until heated through. Avoid microwaving if possible to keep that luscious cheesy texture intact.
FAQs
Can I use other types of cheese besides Gruyère or Swiss?
Absolutely! Cheeses like mozzarella, Fontina, or even a sharp cheddar can work well, although Gruyère gives the classic nutty, melty quality that pairs best with the onions and potatoes.
Do I have to caramelize the onions for so long?
Slow caramelization is key for developing the deep, sweet flavor that makes this dish special. Rushing this step might leave the onions less flavorful and impact the overall taste of the bake.
Can I make this recipe dairy-free or vegan?
While the cream and cheese are central to the indulgent texture, you could substitute plant-based milk, vegan butter, and vegan cheese alternatives, though the flavor profile and creaminess will be different.
Is it better to use Yukon gold or russet potatoes?
Both work well. Yukon golds are naturally buttery and hold their shape nicely, while russets become fluffier and softer, making the bake creamier. Choose based on your texture preference.
Can I add other vegetables to this bake?
Yes! Sliced mushrooms or sautéed spinach make great additions to add more earthiness and nutrition, complementing the onions and cheesy potatoes beautifully.

Ingredients
Potatoes
- 2 lbs (900g) Yukon gold or russet potatoes, thinly sliced
Onion Mixture
- 2 large onions, thinly sliced
- 2 tbsp butter
- 1 tbsp olive oil
- 2 cloves garlic, minced
Dairy & Cheese
- 1 cup grated Gruyère or Swiss cheese
- 1/2 cup Parmesan cheese
- 1 cup heavy cream
- 1/2 cup milk
Seasoning & Garnish
- Salt & pepper to taste
- Fresh thyme (optional, for garnish)
Instructions
- Preheat and Prepare: Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish to prevent sticking and facilitate easy cleanup.
- Caramelize the Onions: In a large skillet, melt the butter with olive oil over low heat. Add the thinly sliced onions and cook slowly for 25–30 minutes until they are deeply golden and caramelized. Stir in the minced garlic and cook for an additional minute to infuse the flavors.
- Mix Cream and Cheese: In a separate bowl, combine the heavy cream, milk, salt, pepper, and half of the grated Gruyère and Parmesan cheeses. This mixture will provide the creamy base and cheesy flavor for the bake.
- Layer the Ingredients: Arrange half of the sliced potatoes evenly in the prepared baking dish. Spread half of the caramelized onion mixture over the potatoes, followed by half of the cream and cheese mixture. Repeat these layers with the remaining potatoes, onions, and cream mixture to build the dish.
- Top and Bake: Sprinkle the remaining cheese on top to create a deliciously golden crust. Cover the dish with foil and bake for 40 minutes. Then remove the foil and continue baking for another 15–20 minutes until the top is bubbly and golden brown.
- Rest and Garnish: Allow the bake to rest for 10 minutes to set and cool slightly. Garnish with fresh thyme, if desired, before serving to add an aromatic touch.
Notes
- Using Yukon gold potatoes adds a creamy texture, but russet potatoes also work well for a fluffier finish.
- Slow caramelization of onions is key to develop deep, sweet flavors—do not rush this step.
- Gruyère cheese can be substituted with Swiss cheese for a milder taste.
- For a lighter version, substitute half-and-half or whole milk for heavy cream, though it may reduce creaminess.
- This dish is best served warm and is perfect as a comforting side or a vegetarian main course.
