- 2 pounds baby potatoes, halved: Choose smooth, firm potatoes to ensure even roasting and a creamy interior.
- 1 packet (1 oz) French onion soup mix: The star seasoning that infuses the potatoes with rich, savory onion flavor and herbs.
- 3 tablespoons olive oil: Helps to crisp the potatoes beautifully while adding a fruity depth.

How to Make French Onion Potatoes Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 400°F (200°C). Lightly grease a baking dish or sheet to prevent sticking and make cleanup easier. This prep sets the stage for perfectly roasted potatoes.
Step 2: Season the Potatoes
In a large bowl, toss your halved baby potatoes with olive oil and the entire packet of French onion soup mix. Make sure all the potatoes are evenly coated so every bite is packed with that classic onion herb goodness.
Step 3: Roast Until Golden
Spread the seasoned potatoes out in a single layer on your prepared baking dish. Roast them in the oven for 25 to 30 minutes, stirring halfway through to ensure even cooking. You’ll know they’re ready when they turn tender inside and develop a gorgeous golden crisp outside.
Step 4: Add the Cheese
Sprinkle shredded cheese evenly over the hot potatoes and return the dish to the oven. Bake for another 5 to 7 minutes until the cheese melts into irresistibly bubbly, golden perfection. This step transforms simple roasted potatoes into a luscious, cheesy delight.
Step 5: Garnish and Serve
Finish your French Onion Potatoes Recipe with a sprinkle of fresh chopped parsley for a burst of color and freshness. Serve immediately while hot and enjoy the comforting layers of textures and flavors you’ve created.

Garnishes
Fresh parsley is a simple but beautiful garnish that lifts the rich flavors and adds a pop of green. You can also experiment with a sprinkle of finely grated Parmesan or a dash of smoked paprika for a subtle smoky note.
Side Dishes
These potatoes pair wonderfully with roasted meats like chicken, beef, or pork, soaking up any accompanying sauces. They also complement a vibrant green salad or steamed vegetables if you’re aiming for a lighter meal without sacrificing flavor.
Creative Ways to Present
Try serving the French Onion Potatoes Recipe in individual ramekins topped with cheese and parsley for a charming presentation at dinner parties. Alternatively, layer them in a baking dish with caramelized onions for an even more indulgent experience that feels like an elevated side dish.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftovers to an airtight container and keep them in the refrigerator. They will stay fresh for up to 3 days, making this recipe a perfect candidate for easy weekday meals or meal prep.
Freezing
While best enjoyed fresh, you can freeze French Onion Potatoes for up to a month. Place cooled potatoes in a freezer-safe container, and thaw overnight in the refrigerator before reheating to preserve the flavors and texture.
Reheating
Reheat leftovers in the oven at 350°F (175°C) to maintain the crispy edges and melty cheese. Avoid microwaving if you want to keep that desirable roast texture intact, but if in a hurry, short bursts in the microwave work fine too.
FAQs
Can I use other types of potatoes for this recipe?
Absolutely! While baby potatoes work best for even roasting and tender texture, you can use fingerlings or small Yukon golds. Just remember to cut larger potatoes into smaller pieces so they cook through evenly.
Is it necessary to use French onion soup mix, or can I make my own seasoning?
The French onion soup mix is key to getting that authentic flavor easily, but if you prefer, you can blend your own combination of dried onion flakes, beef bouillon, thyme, and parsley. This gives you more control over salt and seasoning intensity.
Can I make this recipe vegan?
Yes! Simply swap out the cheese for your favorite vegan cheese alternative, and double-check that your soup mix does not contain animal products. Olive oil and fresh herbs will keep the dish flavorful and satisfying.
How crispy do the potatoes get in this recipe?
The roasting process creates a lovely golden crust on the outside while keeping the insides tender and creamy. Adding the cheese at the end adds a gooey topping instead of additional crisp, balancing the textures perfectly.
What cheese works best for this recipe?
Gruyère is the classic choice and adds a nutty sweetness, but Swiss or mozzarella cheeses are great alternatives offering meltiness and a mild flavor that complements the savory onion seasoning beautifully.
