Ingredients You’ll Need

This French Onion Potatoes Recipe calls for a handful of simple ingredients that come together beautifully to create a dish bursting with flavor, golden color, and the perfect crispy texture. Each ingredient plays an essential role in making this recipe a standout.

  • Baby potatoes: Use about 2 pounds, halved or quartered for perfect bite-sized pieces that roast evenly and develop crispy edges.
  • French onion soup mix (1 ounce): This is the secret to infusing savory, caramelized onion flavor without extra fuss.
  • Olive oil (3 tablespoons): Helps the potatoes roast to crispy perfection and adds a subtle fruity richness.
  • Garlic powder (1 teaspoon): Adds depth and a gentle garlic note that complements the onion soup mix wonderfully.
  • Black pepper (½ teaspoon): Gives just a touch of heat and balances the overall flavor.
  • Salt (optional, ½ teaspoon): Add only if your soup mix isn’t already salty enough.
  • Chopped fresh parsley (2 tablespoons, optional): A fresh, vibrant garnish that adds a pop of color and brightness to the finished dish.

How to Make French Onion Potatoes Recipe

Step 1: Preheat and Prepare

Start by heating your oven to 400°F (200°C). This temperature is key to achieving that perfect balance of tender insides and crisp, golden edges on the potatoes.

Step 2: Toss the Potatoes

In a large bowl, combine the halved or quartered baby potatoes with the French onion soup mix, olive oil, garlic powder, black pepper, and salt if you’re using it. Toss everything thoroughly so each piece is evenly coated with that savory, seasoned oil that will caramelize beautifully in the oven.

Step 3: Arrange on Baking Sheet

Spread the potatoes out in a single layer on a baking sheet lined with parchment paper or lightly greased. Ensure they’re not too crowded—that’s the secret to getting them nicely crisp on the outside.

Step 4: Roast to Perfection

Place the baking sheet in the preheated oven and roast the potatoes for 35 to 40 minutes. Flip them halfway through the cooking time to guarantee even roasting and that irresistible golden crust all over.

Step 5: Garnish and Serve

Once your French Onion Potatoes are golden brown and crispy, remove them from the oven. Sprinkle with fresh chopped parsley if you want to add a fresh, herbaceous touch before serving.

Garnishes

Fresh parsley is a classic choice that brightens the earthiness of the potatoes, but you could also add a sprinkle of grated Parmesan or a handful of crispy fried onions for extra texture and flavor. A light drizzle of sour cream on the side can add a creamy tang that pairs beautifully, too.

Side Dishes

This French Onion Potatoes Recipe pairs exceptionally well with grilled meats like steak, roasted chicken, or pork chops. It’s also fantastic alongside a crisp green salad or steamed veggies, making for a well-rounded and satisfying meal.

Creative Ways to Present

For a fun twist, serve these potatoes in mini cast iron skillets or rosemary sprigs scattered on top for an aromatic garnish. You can also layer them in a cozy casserole dish with melted cheese on top, turning this side into a decadent, shareable treat perfect for gatherings.

Make Ahead and Storage

Storing Leftovers

Place any leftover French Onion Potatoes in an airtight container and refrigerate for up to 3 days. Storing them properly helps maintain their flavor while keeping them safe to enjoy later.

Freezing

If you’d like to freeze these potatoes, spread them on a baking sheet in a single layer and freeze until firm. Then transfer to a freezer-safe bag or container. They’ll keep well for up to 2 months, ready for you to reheat from frozen whenever a craving strikes.

Reheating

To bring leftovers back to crispy life, reheat in a 375°F oven for about 10-15 minutes or until warmed through and crisp. Avoid microwaving when possible, as it tends to make the potatoes soggy.

FAQs

Can I use other types of potatoes in this French Onion Potatoes Recipe?

Absolutely! While baby potatoes are ideal for their size and texture, Yukon Gold or red potatoes cut into bite-sized pieces work wonderfully and result in slightly different but equally delicious textures.

Is the French onion soup mix gluten-free?

Many French onion soup mixes contain gluten, so if you require a gluten-free option, check the label carefully or opt for a gluten-free mix or make your own blend with dried onions and gluten-free seasonings.

Can I add cheese to this dish?

Yes! For a cheesy version, sprinkle shredded Gruyère or mozzarella over the potatoes during the last 5 minutes of baking. It melts beautifully and adds a creamy richness that makes the dish even more indulgent.

How crispy will these potatoes get?

Because they roast at a relatively high temperature and are coated in oil, the outer edges get satisfyingly crisp while the interior stays tender and creamy. Flipping halfway through cooking ensures even crispiness.

Is this recipe suitable for vegetarians?

Definitely! This recipe contains no meat products and is perfect for vegetarians, especially when served with a vegetarian-friendly soup mix and paired with other plant-based sides.

Final Thoughts

This French Onion Potatoes Recipe is one of those deliciously simple dishes that feels special every time you make it. It combines classic, comforting flavors with a satisfying texture that keeps everyone coming back for more. So don’t hesitate—grab those baby potatoes, toss them with the soup mix and spices, and get ready to enjoy one of the easiest, tastiest sides you’ll want to serve again and again.
