Ingredients You’ll Need

It’s truly amazing what you can achieve with just a handful of simple ingredients! Each one plays a key role in building the irresistible flavors and textures of French Onion Potatoes — from creamy baby potatoes to gooey cheese and that iconic onion soup burst.

• Baby potatoes (2 pounds, halved): Their tender, buttery texture soaks in all the flavors and bakes up beautifully.
• Olive oil (2 tablespoons): Helps crisp and brown the potatoes, while adding a subtle flavor.
• Dry French onion soup mix (1 packet, 1 oz): The star ingredient bringing effortless savory depth and aromatic onion notes.
• Mozzarella cheese (1 cup, shredded): Melts to gooey perfection, creating that irresistible cheese pull.
• Cheddar cheese (1/2 cup, shredded): Adds a bit more color, tang, and extra cheesy richness.
• Unsalted butter (2 tablespoons, melted): Coats the potatoes for more flavor and a silky finish.
• Sour cream (1/4 cup, optional): Dolloped on top for those who love a bit of creamy cool contrast.
• Chopped fresh parsley: For a fresh, vibrant garnish that makes the whole dish pop.

How to Make French Onion Potatoes

Step 1: Preheat and Prep

Begin by preheating your oven to 400°F (200°C). This ensures the potatoes will roast evenly and develop that golden roasted edge we all crave. Lightly grease a 9×13-inch baking dish, so nothing sticks — cleanup is a breeze later!

Step 2: Toss the Potatoes

In a large mixing bowl, combine the halved baby potatoes, olive oil, melted butter, and the packet of French onion soup mix. Give everything a really good toss, making sure each potato gets its fair share of that rich, savory coating. It’s this step that locks in all that flavor to every bite of your French Onion Potatoes.

Step 3: Layer and Bake Covered

Spread the coated potatoes out in your greased baking dish so they’re in a nice, even layer. Cover tightly with foil, which helps steam and soften the potatoes as they bake. Slide them into the oven and let them cook for 30 minutes, filling your kitchen with mouthwatering aromas!

Step 4: Add Cheese and Finish Baking

After that first bake, remove the dish from the oven (careful, it’s hot!) and take off the foil. Give the potatoes a quick stir, then sprinkle the mozzarella and cheddar cheese evenly over the top. Return the dish to the oven uncovered, and bake for another 15–20 minutes, until the potatoes are fork-tender and the cheese is bubbled and gloriously golden brown.

Step 5: Garnish and Serve

When your French Onion Potatoes emerge from the oven, shower them with chopped fresh parsley for a bright touch. If you like, add a dollop of sour cream to each serving, and watch as everyone dives in, eager for that first cheesy bite.

How to Serve French Onion Potatoes

Garnishes

A sprinkle of fresh parsley is the classic touch, adding contrast and color to the golden, cheesy top. A spoonful of sour cream on the side brings a cool tang that pairs perfectly with the savory flavors. You can also dust with a bit of freshly cracked black pepper or finely sliced chives for extra flair.

Side Dishes

These French Onion Potatoes are totally versatile! Serve them with roasted chicken, steak, or pork chops for a hearty main attraction. They also stand out at holiday tables alongside ham, turkey, green beans, or a crisp salad. Honestly, they’re so satisfying, they could even star as a vegetarian main with a simple green side.

Creative Ways to Present

If you’re aiming for a show-stopping spread, try baking and serving French Onion Potatoes in individual ramekins for a personal touch. Or, scoop them into a crispy potato skin shell for a hand-held party snack. Layer leftovers on flatbread for a quick, cheesy potato pizza, or tuck some into an omelet for a brunch twist!

Make Ahead and Storage

Storing Leftovers

Pop any cooled leftovers into an airtight container and refrigerate. The cheesy potatoes stay delicious for up to 4 days, making them perfect for packed lunches or effortless dinners.

Freezing

If you want to get ahead, you can freeze French Onion Potatoes after they’ve cooled. Use a freezer-safe dish and wrap tightly. For the best texture, thaw in the refrigerator before reheating — keep in mind the cheese may lose a little creaminess after freezing, but the flavor will remain cozy and rich.

Reheating

To recapture that fresh-from-the-oven glory, reheat French Onion Potatoes in a 350°F oven, covered with foil, until hot (about 15-20 minutes). For smaller portions, a quick zap in the microwave works too, though the oven helps keep the edges nice and crispy.
