- 2 pounds baby potatoes, halved: Choose tender baby potatoes for even roasting and a perfect bite-sized texture.
- 1 packet (1 oz) French onion soup mix: This is the heart of the recipe, imbuing the potatoes with deep, savory onion and herb flavors.
- 3 tablespoons olive oil: Helps to crisp the potatoes beautifully and enhances the rich flavor profile.

How to Make French Onion Potatoes Recipe
Step 1: Preheat Your Oven
Get started by preheating your oven to 400°F (200°C). Preparing the oven ahead ensures that your potatoes start roasting immediately, locking in flavor and creating that delightful crispy edge we all love. Lightly grease your baking dish or sheet to prevent sticking and make cleanup easier.
Step 2: Season the Potatoes
In a large bowl, toss your halved baby potatoes with olive oil and the French onion soup mix. This step is crucial—the olive oil helps each potato get evenly coated, while the soup mix showers them with deep onion, garlic, and herb spices. Make sure every piece is well-coated for maximum flavor in every bite.
Step 3: Roast Until Golden
Spread the seasoned potatoes evenly on your prepared baking sheet or dish. Let them roast in the oven for 25-30 minutes, turning halfway through to ensure even cooking and to develop that perfect golden-brown crust. You’ll notice the irresistible aroma starting to fill your kitchen at this stage!
Step 4: Add the Cheese
Once the potatoes are tender and golden, sprinkle your chosen shredded cheese generously over the top. Pop them back in the oven for another 5-7 minutes, or until the cheese melts into a bubbly, slightly browned blanket that ties all the flavors beautifully together.
Step 5: Garnish and Serve
Finish your French Onion Potatoes Recipe by sprinkling freshly chopped parsley over the melty cheese. This final touch adds a pop of green color as well as a fresh herbal note, making the dish as pleasing to the eye as it is to the palate. Serve hot and watch everyone dig in with joy!
How to Serve French Onion Potatoes Recipe

Garnishes
Fresh parsley is classic, but you can also sprinkle some chopped chives, or even a pinch of smoked paprika for a subtle smokiness. These garnishes elevate the presentation and layer in extra flavor complexity, enhancing each bite and impressing at the table.
Side Dishes
This French Onion Potatoes Recipe pairs beautifully with juicy grilled meats, roasted chicken, or a fresh green salad. Think about complementary textures and flavors such as crisp greens or a creamy cucumber dip to balance the richness of the cheesy onions and potatoes.
Creative Ways to Present
For a family dinner, serve the potatoes family-style in a rustic ceramic dish straight from the oven. For an intimate gathering, portion the potatoes into individual ramekins topped with a sprinkle of cheese and parsley, creating a charming and elegant touch everyone will admire.
Make Ahead and Storage
Storing Leftovers
Any leftover French Onion Potatoes Recipe can be stored in an airtight container in the refrigerator for up to 3 days. Make sure the potatoes have cooled completely before sealing to maintain freshness and avoid sogginess.
Freezing
While these potatoes are at their best fresh, you can freeze leftover cooked potatoes in a freezer-safe container for up to 2 months. Note that the texture may soften slightly after freezing, but reheating can bring back much of their original charm.
Reheating
To reheat, use a 350°F (175°C) oven or toaster oven so the potatoes remain crispy and the cheese melts again beautifully. Avoid the microwave if possible, as it can lead to a soggy texture.
FAQs
Can I use regular yellow potatoes instead of baby potatoes?
Absolutely! Just cut them into smaller, uniform pieces to ensure they cook evenly and achieve that crispy outside with tender inside.
What kind of cheese works best for this recipe?
Gruyère and Swiss add a rich, nutty flavor, while mozzarella offers stretchiness and gooeyness. Feel free to experiment or mix cheeses for your favorite cheesy finish.
Is there a dairy-free option for the cheese topping?
Yes! You can use a dairy-free cheese alternative that melts well, or skip cheese entirely and finish with a sprinkle of nutritional yeast for a cheesy flavor without dairy.
Can I make this recipe vegan?
By using plant-based cheese and ensuring the French onion soup mix contains no animal-derived ingredients, this recipe can easily be adapted to vegan diets.
How can I add more herbs to the French Onion Potatoes Recipe?
Feel free to toss in fresh rosemary, thyme, or oregano with the potatoes before roasting for an herbaceous twist that complements the onion flavor beautifully.
