Ingredients You’ll Need

One of the beauties of French Onion Potatoes is how a handful of humble ingredients can create something truly memorable. Each component plays a crucial role — from the savory punch of the onion soup mix to the gooey combo of cheeses — making every bite rich, flavorful, and incredibly satisfying.

Baby potatoes (2 pounds, halved): These little spuds roast up creamy inside, crisp outside, and soak up all those gorgeous flavors.
Olive oil (2 tablespoons): Adds richness and helps everything roast beautifully, giving the potatoes a golden edge.
Dry French onion soup mix (1 packet, 1 oz): The secret ingredient for intense flavor with zero fuss — it infuses every bite with bold, savory onion taste.
Shredded mozzarella cheese (1 cup): This cheese melts perfectly, lending gooeyness and a bit of stretch on top.
Shredded cheddar cheese (1/2 cup): Cheddar brings sharpness and vibrant color, balancing out the mild mozzarella.
Unsalted butter (2 tablespoons, melted): Just a touch for that rich, irresistible finish on your potatoes.
Sour cream (1/4 cup, optional): For serving — a cool, creamy dollop gives each forkful extra decadence.
Chopped fresh parsley (garnish): This adds a pop of freshness and color to your finished dish.

How to Make French Onion Potatoes

Step 1: Prep the Ingredients

Start by preheating your oven to 400°F (200°C). Halve your baby potatoes and gather up all your ingredients — trust me, having everything set up before you start makes this dish come together effortlessly. Grease a 9×13-inch baking dish, so those potatoes slide right out at the end.

Step 2: Toss and Coat

In a large mixing bowl, combine the halved potatoes, olive oil, dry French onion soup mix, and melted butter. Toss everything together until each potato piece is evenly coated in the savory mixture. The potatoes should glisten, and you’ll notice the tantalizing aroma of onion and spices already building.

Step 3: Arrange and Bake (Covered)

Transfer the coated potatoes into your prepared baking dish, spreading them out in a single, even layer to ensure even roasting. Cover the dish with aluminum foil and slide it into the oven. Bake for 30 minutes, letting the potatoes steam and begin to absorb those French onion flavors.

Step 4: Add the Cheese and Finish Baking

Carefully remove the foil, give those potatoes a quick stir, and then sprinkle both the mozzarella and cheddar cheeses evenly over the top. Return the dish to the oven uncovered. Bake for another 15–20 minutes, until the potatoes are fork-tender and the cheese is melted, golden, and bubbling at the edges. It’ll smell so good, you’ll want to dive in immediately.

Step 5: Garnish and Serve

As soon as the French Onion Potatoes come out of the oven, dust them with a generous sprinkle of freshly chopped parsley. Let them sit for a minute or two (if you can wait that long!), then serve warm with dollops of sour cream if you like.

How to Serve French Onion Potatoes

Garnishes

Brighten up the rich, cheesy dish with a shower of finely-chopped fresh parsley — it adds a pop of herbaceous flavor and gorgeous color contrast to the French Onion Potatoes. If you’re feeling fancy, a little extra freshly cracked pepper or even some sliced green onions are great, too. And don’t forget that cool, creamy dollop of sour cream: it’s the perfect finishing touch!

Side Dishes

French Onion Potatoes make an incredible partner for roasted or grilled meats like chicken, steak, or pork chops. They’re also dreamy alongside a holiday spread with glazed ham or roast turkey. For a vegetarian feast, serve them with sautéed greens and a crisp salad — the cheesy, deeply savory potatoes will be the star of any meal.

Creative Ways to Present

Serve French Onion Potatoes in mini cast-iron skillets for a rustic, charming touch at dinner parties. Or, portion them in individual ramekins for elegant plating at gatherings. You can also scoop leftovers into baked potato skins and broil with extra cheese for a fun appetizer twist!

Make Ahead and Storage

Storing Leftovers

Pop any leftover French Onion Potatoes into an airtight container and refrigerate within two hours of serving. They’ll stay delicious for up to 3–4 days, and honestly, reheated potatoes can taste even richer as the flavors meld!

Freezing

If you want to freeze the leftovers, let the potatoes cool completely, then transfer to a freezer-safe dish. They’ll keep their flavor and texture well for up to two months. When you’re ready to enjoy, thaw overnight in the refrigerator for best results.

Reheating

For the best texture, reheat the French Onion Potatoes in the oven at 350°F until warmed through and the cheese is bubbly again (about 15 minutes). You can also use the microwave for a quick fix, but the oven gives back some of that lovely crispy top.

FAQs

Can I use regular potatoes instead of baby potatoes?

Absolutely! Just cut larger Yukon gold or red potatoes into chunks about the size of halved baby potatoes. The texture and bake time will be quite similar.

Can I make French Onion Potatoes ahead of time?

Yes, you can toss and assemble everything in your baking dish up to a day in advance. Refrigerate, then bake as directed, adding a few extra minutes if baking straight from the fridge.

Is sour cream necessary?

Sour cream is totally optional but highly recommended for a creamy, cool contrast to the cheesy, warm potatoes. Greek yogurt is a good substitute if you’re looking for something lighter.

Can I make this dish vegan?

Definitely! Use vegan cheese shreds and substitute plant-based butter. Double-check your onion soup mix to make sure it’s vegan-friendly, and the results will be just as crave-worthy.

What can I do to make the potatoes crispier?

For extra crispy French Onion Potatoes, you can skip the initial foil covering and roast them uncovered. Stir them halfway through, and you’ll get beautifully golden, crisp edges.

Final Thoughts

French Onion Potatoes check every comfort food box — creamy, cheesy, savory, and so deliciously simple to make. Whether you’re feeding a crowd or just want something special on a regular weeknight, these potatoes might just become your new go-to side. Give this cozy recipe a try and watch how fast they disappear!
