Whether you’re craving a cozy side for dinner or looking to seriously upgrade a potluck, this recipe will become your new favorite. The best part?

Ingredients You’ll Need
If ever there was a side dish that proved simple ingredients can create big flavors, it’s French Onion Potatoes. Each component here has a specific job: bringing crunch, body, aroma, or just tying all that irresistible flavor together. Here’s what you’ll need and why you shouldn’t skip a single one!
- Baby potatoes: These tiny spuds roast up with crispy edges and creamy interiors—perfection in every bite.
- French onion soup mix: The flavor foundation! It transforms the potatoes into a savory, slightly sweet, umami-packed masterpiece.
- Olive oil: Helps the seasoning cling and guarantees golden, crunchy bits on every potato chunk.
- Garlic powder: Adds depth and a gentle warmth that blends beautifully with the onion flavors.
- Black pepper: For just the right kick and a touch of peppery balance.
- Salt (optional): Some soup mixes are already salty, so taste before you add more, but just a pinch can really make the flavors pop.
- Fresh parsley (optional for garnish): Sprinkling this on at the end adds a burst of color and a touch of herby brightness.
How to Make French Onion Potatoes
Step 1: Prep Your Oven and Baking Sheet
Start by preheating your oven to 400°F (200°C). Line a large baking sheet with parchment paper or give it a quick mist of nonstick spray. This guarantees easy cleanup and helps the potatoes roast evenly without sticking.
Step 2: Toss the Potatoes
In a big mixing bowl, combine your halved or quartered baby potatoes, French onion soup mix, olive oil, garlic powder, black pepper, and salt if you’re using it. Get your hands in there! Toss everything together until every potato piece is thoroughly coated in that flavorful mix—this is the secret to that amazing crust later on.
Step 3: Arrange and Roast
Spread the coated potatoes out in a single layer on your prepared baking sheet. Space them out for maximum crispiness. Pop the tray into your hot oven and roast for 35 to 40 minutes, flipping them with a spatula halfway through. This ensures every edge gets golden and crunchy while the insides stay pillowy and moist.
Step 4: Garnish and Serve
When your French Onion Potatoes are deeply golden and irresistibly crisped at the edges, pull them from the oven. If you like, shower them with fresh chopped parsley for a gorgeous finish. Serve them piping hot and watch them disappear!
How to Serve French Onion Potatoes

Garnishes
Even the simplest garnish can make French Onion Potatoes look and taste extra special. Fresh chopped parsley or chives add color and a fresh pop of flavor, while a sprinkle of lemon zest offers unexpected brightness. For indulgence, a light dusting of grated Gruyère or mozzarella during the last few minutes in the oven sends these potatoes straight into comfort food heaven.
Side Dishes
French Onion Potatoes pair beautifully with hearty mains. Try them alongside roasted chicken, grilled steak, or your favorite vegetarian protein. They also shine next to braised dishes or a crisp dinner salad—basically, wherever you’d serve traditional oven-roasted potatoes, these are a welcome upgrade!
Creative Ways to Present
Get playful with your presentation! Pile French Onion Potatoes into a rustic serving bowl for a family-style vibe. Or skewer them onto toothpicks for a cocktail party snack. Tuck them into lunch wraps with greens and cheese, or layer them into casseroles for extra flavor—this recipe is a true chameleon.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers (lucky you!), stash them in an airtight container in the fridge. They’ll keep well for up to 4 days and maintain that wonderful flavor, although the edges may soften a bit over time.
Freezing
You can absolutely freeze French Onion Potatoes! Spread the cooled potatoes on a baking sheet and freeze in a single layer, then transfer to a zip-top freezer bag. They’ll keep for up to two months. Just remember to reheat from frozen for best texture.
Reheating
To bring back their crispiness, reheat leftover French Onion Potatoes in a 400°F oven for 10 minutes or until hot and crunchy again. The microwave will work in a pinch, but the edges won’t be quite as crisp—use the oven if you can!
FAQs
Can I use regular potatoes instead of baby potatoes?
Absolutely! Yukon Gold or red potatoes are delicious substitutes. Just cut them into bite-sized chunks for even roasting and that classic French Onion Potatoes look and feel.
Is it possible to make this recipe vegan?
Yes, most store-bought French onion soup mixes are vegan, but it’s always smart to double-check the label. The rest of the ingredients are plant-based, so you’re good to go.
How do I make my potatoes extra crispy?
The key is spreading the potatoes in a single layer and making sure they aren’t crowded on the pan. Also, flipping them halfway through roasting helps every edge get crisp.
Can I add cheese to French Onion Potatoes?
Definitely! Shredded Gruyère, mozzarella, or Swiss added in the last five minutes of roasting will create melty, bubbly perfection and pair beautifully with the onion flavors.
What protein dishes pair best with these potatoes?
French Onion Potatoes complement roast chicken, pan-seared steak, or herby baked tofu especially well. Their savory depth brings warmth to practically any main dish, making them the ultimate dinner sidekick.
Final Thoughts
There’s a lot to love about these French Onion Potatoes—from their toasty edges to those layers of savory, oniony flavor. Whether you’re serving them for a weekday dinner or putting them out at a festive gathering, they never fail to win over a crowd. Go ahead, give them a try and prepare to fall head over heels for your new favorite side!
