Ingredients You’ll Need
This recipe is wonderfully straightforward, relying on a handful of pantry staples and fresh ingredients that pack a punch. Each component contributes something unique—baby potatoes for that creamy bite, onions for sweetness, and the soup mix for that iconic French onion zest that ties everything together beautifully.
- 2 pounds baby potatoes (halved): Choose firm, evenly-sized potatoes for quick, consistent roasting.
- 2 tablespoons olive oil: Adds richness while helping the potatoes crisp up nicely in the oven.
- 1 large yellow onion (thinly sliced): Caramelizing this slowly brings out luscious sweetness and depth.
- 1 packet (1 oz) French onion soup mix: The secret ingredient that infuses the dish with signature savory, onion-forward notes.
- 2 tablespoons unsalted butter: Lends a velvety texture and enhances the caramelization process for the onions.
- 1 teaspoon garlic powder: Introduces a subtle, warm garlic undertone without overpowering the dish.
- ½ teaspoon black pepper: Adds a gentle heat for balance.
- ½ teaspoon salt (optional): Use carefully as the soup mix already contains sodium; adjust to taste.
- 1 tablespoon fresh parsley (chopped, for garnish): Provides a fresh, bright contrast and lovely color on the finished dish.
How to Make French Onion Potatoes Recipe
Step 1: Caramelize the Onions
Begin by heating the butter and olive oil together in a large skillet over medium heat. Add your thinly sliced yellow onions and let them cook slowly, stirring now and then. After about 8 to 10 minutes, they will transform into soft, golden brown ribbons. This step is crucial—it gently releases the natural sugars and creates that deep, sweet flavor that every bite of this dish celebrates.
Step 2: Prepare the Potato Mixture
While your onions are working their magic, place the halved baby potatoes in a big mixing bowl. Sprinkle in the French onion soup mix, garlic powder, black pepper, and a pinch of salt if you find it necessary. When the onions are ready, stir them in and toss everything together until the potatoes are completely coated in the glorious onion goodness. This coating is what sets this recipe apart and guarantees every roast potato is bursting with flavor.
Step 3: Roast the Potatoes
Transfer the potato and onion mixture into a greased 9×13 baking dish or a large sheet pan for even roasting. Slide it into your preheated 400°F oven and roast for 35 to 40 minutes. Be sure to stir the mixture once halfway through baking so all sides get that beautiful golden color and tender finish. The result? Crispy edges paired with a soft, fluffy inside — pure deliciousness!
Step 4: Garnish and Serve
Just before serving, sprinkle fresh chopped parsley over the top to add a pop of color and a fresh herbal hint. If you want to take things up a notch, sprinkle shredded Gruyère or Swiss cheese during the last few minutes of baking. This French Onion Potatoes Recipe transforms easily into an indulgent treat anyone will rave about.
How to Serve French Onion Potatoes Recipe
Garnishes
Fresh parsley is a classic choice, lending a bright contrast to the rich potatoes and caramelized onions. You can also add a sprinkle of finely chopped chives or a small handful of grated cheese for extra flair. These garnishes not only make the dish look irresistible but also add layers of fresh flavor.
Side Dishes
This French Onion Potatoes Recipe pairs exceptionally well with grilled steaks, roasted chicken, or even a holiday ham. Its savory and slightly sweet profile complements meats beautifully, but it also stands alone as a hearty vegetarian side dish that everyone will love.
Creative Ways to Present
For a fun twist, serve these potatoes in individual ramekins topped with melted cheese and a sprinkle of fresh herbs. Alternatively, turn them into a baked potato bar with various toppings like sour cream, bacon bits, and scallions for guests to customize their own. The comforting flavors lend themselves to many creative presentations, perfect for entertaining.
Make Ahead and Storage
Storing Leftovers
Store any leftover French Onion Potatoes Recipe in an airtight container in the refrigerator for up to three days. The flavors meld even more after resting, making the leftovers delicious and easy to reheat for busy nights.
Freezing
You can freeze the roasted potatoes by placing them in a freezer-safe container or bag, separated in single layers for easy portioning. They keep well for up to two months. However, keep in mind that the texture may soften slightly after thawing and reheating due to the moisture content in the potatoes.
Reheating
To reheat, warm the potatoes in a 350°F oven for about 15 minutes until heated through and crisp on the edges again. You can also reheat them in a skillet over medium heat with a little olive oil for that freshly roasted crunch.
FAQs
Can I use other types of potatoes for the French Onion Potatoes Recipe?
