Ingredients You’ll Need

The beauty of French Onion Potatoes is that each ingredient is both humble and essential, coming together to transform ordinary spuds into a crave-worthy, cheesy masterpiece. Here’s how each element boosts the flavor, texture, and appearance:

• Baby potatoes or Yukon gold potatoes: Their creamy texture and natural sweetness ensure every bite is buttery and satisfying; halve or quarter them for optimal crispiness and flavor absorption.
• Olive oil: A little bit of rich olive oil helps the soup mix and seasonings cling perfectly to each potato chunk, promoting golden edges as they roast.
• French onion soup mix: The signature, can’t-miss flavor bomb, this brings all the deep, caramelized onion deliciousness in a single step.
• Garlic powder: This subtle addition gives a warming, aromatic undertone that perfectly complements the onion while elevating the entire dish.
• Salt and pepper: Simple but essential for balancing the flavors—add to taste, especially after the soup mix, to avoid oversalting.
• Shredded mozzarella or Swiss cheese: Melts into a dreamy, bubbly topping that makes the potatoes utterly irresistible; choose Swiss for a more traditional French onion flavor or mozzarella for creamy mildness.
• Chopped fresh parsley: Don’t skip the finishing sprinkle! It brightens and freshens up the savory richness with a pop of color and herbal aroma.
• Nonstick cooking spray: A quick mist ensures an easy release and hassle-free cleanup so every potato makes it to your plate, not stuck to the pan.

How to Make French Onion Potatoes

Step 1: Prep Your Pan and Preheat

Start by preheating your oven to 400°F (200°C) — this creates the perfect roasting environment for crispy edges and soft centers. Lightly coat a 9×13-inch baking dish with nonstick cooking spray so nothing sticks and cleanup is a breeze. This step is crucial for getting those golden brown bottoms without frustration later!

Step 2: Mix Potatoes and Seasonings

Grab a big mixing bowl and toss in your halved or quartered potatoes. Drizzle them with the olive oil, then sprinkle over the French onion soup mix, garlic powder, and a pinch each of salt and pepper. Using clean hands or a sturdy spatula, give everything a thorough toss until every piece is well coated and glistening. The potato pieces should be glossy and speckled with all that savory seasoning.

Step 3: Layer and Cover for the First Bake

Spread the seasoned potatoes in an even layer in your prepared pan. Cover the dish tightly with foil—this traps steam and helps the potatoes become fork-tender while soaking up every bit of flavor. Bake covered for 30 minutes, resisting the urge to peek; you want all that oniony aroma developing under the foil!

Step 4: Add Cheese and Finish Baking

After 30 minutes, carefully remove the foil and give the potatoes a gentle stir so the bottom layer has a chance to brown. Sprinkle the shredded cheese generously over the top, letting it snow down and cling to the potatoes. Return the dish to the oven, this time uncovered, and bake for an additional 10–15 minutes. You’ll know it’s ready when the potatoes are tender and the cheese is golden, bubbling, and too tempting to resist.

Step 5: Garnish and Serve French Onion Potatoes

Once the dish is out of the oven, shower it with fresh parsley for color and a final hint of freshness. Transfer the French Onion Potatoes to the table while hot and bubbly — they’ll steal the show!

Garnishes

A generous handful of freshly chopped parsley makes all the difference in both looks and flavor, but you can also add a few twists of black pepper or even a sprinkle of extra cheese. For a touch of crunch, crispy fried onions or homemade croutons scattered on top will add a little something special to your French Onion Potatoes.

Side Dishes

French Onion Potatoes are a natural partner for grilled or roasted meats, like juicy steak, roast chicken, or pork chops. For a lighter meal, pair them with a crisp green salad, garlicky sautéed greens, or a platter of roasted seasonal veggies. Their savory richness means you don’t need much else—just something fresh to balance out all that cheese and onion goodness!

Creative Ways to Present

Don’t be afraid to get playful: spoon French Onion Potatoes into mini ramekins for an elegant dinner party, or serve them family-style straight from the baking dish for a relaxed gathering. Want to amp up the wow factor? Top with caramelized onions or bacon bits right before serving or offer a build-your-own bar with assorted cheeses and toppings for a customizable side.

Make Ahead and Storage

Storing Leftovers

Once the French Onion Potatoes have cooled completely, transfer any leftovers to an airtight container and keep them in the refrigerator. They’ll stay fresh and delicious for up to four days, making them perfect for quick lunches or midnight cravings.

Freezing

While potatoes can sometimes change texture after freezing, French Onion Potatoes actually freeze quite well because of their rich, cheesy sauce. Just scoop portions into freezer-safe containers and seal tightly. They’ll last in the freezer for up to two months—great for prepping ahead!

Reheating

Reheat individual portions in the microwave or slide the whole batch into a 350°F oven until bubbly and warmed through. For best results, cover with foil so the cheese doesn’t over-brown, and give everything a little stir halfway through. If you revived from frozen, let them thaw overnight in the fridge before reheating.

FAQs

Can I use a different kind of potato in French Onion Potatoes?

Absolutely! While baby potatoes and Yukon golds are favorites for their creamy interiors, you can use russets (peeled and cut into chunks) or even red potatoes. Just aim for roughly even-sized pieces for uniform cooking.

Is it possible to make French Onion Potatoes vegan?

Yes, you can make this dish entirely plant-based by opting for a vegan cheese that melts well and double-checking your French onion soup mix ingredients. Olive oil and the rest of the seasonings work perfectly as is.

How do I keep the potatoes from sticking to the pan?

Spraying your baking dish generously with nonstick spray is key, and tossing the potatoes with olive oil helps too. If you want extra insurance, you can also line the pan with parchment paper before adding your potato mixture.

What’s the best way to get extra crispy potatoes?

Try spreading your potatoes out in a single layer and avoid overcrowding the pan. You can also raise the heat to 425°F for the last few minutes of baking or finish them under the broiler for irresistible crispy tops.

Can I prep French Onion Potatoes in advance?

Definitely! Assemble everything up to the point of baking, cover, and store in the fridge for up to 24 hours. When ready to bake, add a few extra minutes to the covered cooking time to ensure the potatoes are tender all the way through.
