Ingredients You’ll Need

Gathering the right ingredients for this dish is straightforward and rewarding. Each component plays a vital role, from the creaminess and crispness of the baby potatoes to the sweet depth of the caramelized onions and the savory seasoning that ties it all together.

  • 2 pounds baby potatoes (halved): These small potatoes roast beautifully, offering a perfect balance of creamy interior and slightly crisp edges.
  • 2 tablespoons olive oil: Helps achieve a lovely golden roast while adding a subtle fruity richness.
  • 1 large yellow onion (thinly sliced): Caramelizing these slowly brings out their natural sweetness and deep flavor complexity.
  • 1 packet (1 oz) French onion soup mix: The secret seasoning blend that infuses the dish with that unmistakable French onion taste.
  • 2 tablespoons unsalted butter: Adds richness and helps with the buttery texture that coats every bite of potato and onion.
  • 1 teaspoon garlic powder: Enhances the savory profile without overpowering the main flavors.
  • ½ teaspoon black pepper: Provides just the right hint of spice and balance.
  • ½ teaspoon salt (optional): Use according to taste, especially considering the saltiness of the soup mix.
  • 1 tablespoon fresh parsley (chopped, for garnish): Brightens up the dish with fresh color and a light herbal note.

How to Make French Onion Potatoes Recipe

Step 1: Caramelize the Onions

Start by heating the butter and olive oil in a large skillet over medium heat. Once melted and warm, add the thinly sliced yellow onion. Stir occasionally as they cook for 8 to 10 minutes until the onions are soft, golden, and sweet, creating that signature caramelized flavor that is essential for the French Onion Potatoes Recipe.

Step 2: Prepare the Potato Mixture

While your onions are working their magic, place the halved baby potatoes in a large mixing bowl. Add the French onion soup mix, garlic powder, black pepper, and salt if you choose. Then fold in the warm caramelized onions, tossing everything gently until each potato piece is beautifully coated with seasoning and golden onion goodness.

Step 3: Roast to Perfection

Transfer this irresistible mixture into a well-greased 9×13-inch baking dish or a spacious sheet pan. Spread it out evenly, then pop it into your preheated oven at 400°F. Roast for about 35 to 40 minutes, stirring once halfway through to ensure even cooking and browning. Look for golden, tender potatoes with edges that are perfectly crisped.

Garnishes

Once out of the oven, sprinkle fresh chopped parsley over the potatoes for a burst of color and fresh flavor contrast. For an indulgent touch, try adding shredded Gruyère or Swiss cheese during the last five minutes of roasting so it melts beautifully over the potatoes and onions.

Side Dishes

French Onion Potatoes Recipe pairs magnificently with grilled steak, roasted chicken, or even holiday ham. The rich, savory flavor profile complements hearty proteins perfectly, making it a versatile side whether you’re planning a casual dinner or celebrating a special occasion.

Creative Ways to Present

For an eye-catching presentation, serve these potatoes in individual ramekins topped with a sprinkle of cheese and parsley. You can also turn them into a loaded baked potato base by adding sour cream, crispy bacon bits, or caramelized mushrooms for extra layers of flavor and texture.

Make Ahead and Storage

Storing Leftovers

After enjoying your meal, place any leftover French Onion Potatoes Recipe in an airtight container and refrigerate. They’ll keep nicely for up to 3 days, allowing you to enjoy the same comforting flavors without any fuss the next day.

Freezing

If you want to save these potatoes for longer, freeze them in a freezer-safe container for up to one month. To maintain the texture, it’s best to cool them completely before freezing.

Reheating

To bring leftover French Onion Potatoes back to life, warm them in the oven at 375°F for about 15 minutes, or until heated through and slightly crisp. Microwaving works too for convenience but might soften the crispy edges.

FAQs

Can I use other types of potatoes for this recipe?

Absolutely! While baby potatoes work wonderfully, Yukon Gold or red potatoes are great alternatives. Just adjust the roasting time slightly if your pieces are larger.

Is this recipe dairy-free?

The classic version includes butter, which is dairy, but you can substitute with a non-dairy butter or additional olive oil to make it dairy-free without sacrificing flavor.

What if I don’t have French onion soup mix?

You can create a quick homemade version using onion powder, beef or vegetable bouillon, garlic powder, and some herbs. However, the soup mix delivers a unique, convenient flavor that’s tough to replicate perfectly.

Can I add cheese to the French Onion Potatoes Recipe?

Definitely! Adding shredded Gruyère or Swiss cheese in the last few minutes of baking adds richness and a wonderful melt that complements the caramelized onions beautifully.

How spicy is this dish?

This recipe is mild and savory with just a touch of black pepper. It’s not spicy, making it suitable for all palates, including kids and those sensitive to strong heat.
