Ingredients You’ll Need

Here’s what you’ll need to make these creamy, cheesy French Onion Potatoes:

  • 2 pounds baby potatoes – Cut in half or quarters.
  • 1 packet French onion soup mix – The star seasoning of this dish.
  • 3 tablespoons unsalted butter – Melted for rich flavor.
  • 1 tablespoon olive oil – Helps crisp the potatoes while baking.
  • 1 cup shredded cheese – Gruyère, Swiss, or mozzarella work great.
  • ½ cup sour cream – Adds creamy texture.
  • 2 tablespoons fresh parsley – For garnish.
  • Salt & pepper – To taste.

Step-by-Step Instructions

1. Prep the Potatoes

Preheat your oven to 400°F (200°C). Wash and dry the baby potatoes, then cut them into even-sized pieces for even cooking.

2. Season and Toss

In a large bowl, combine potatoes, melted butter, olive oil, and the French onion soup mix. Toss until the potatoes are evenly coated.

3. Bake the Potatoes

Spread the potatoes evenly on a baking sheet or in an oven-safe casserole dish. Bake for 30-35 minutes, stirring halfway through, until they’re golden brown and tender.

4. Make it Cheesy

Once the potatoes are done, sprinkle shredded cheese over the top. Return to the oven for 5 minutes, or until the cheese is fully melted and bubbly.

5. Garnish and Serve

Top with a dollop of sour cream and fresh parsley for a pop of color and flavor. Serve hot alongside roasted chicken, steak, or a fresh salad.

Tips for the Best French Onion Potatoes

  • Use waxy potatoes like Yukon Gold or red potatoes for the best texture.
  • Don’t skip the butter – It gives richness and helps the soup mix stick.
  • Try caramelized onions – For an extra punch of sweet-savory flavor.
  • Mix cheeses – Gruyère for nuttiness, mozzarella for meltiness.
  • Make ahead – Prep the potatoes in the morning, then bake before serving.

Variations You Can Try

  • French Onion Potato Casserole – Add cream of mushroom soup before baking for an even creamier texture.
  • Bacon Lovers’ Version – Stir in cooked, crumbled bacon before adding cheese.
  • Loaded Style – Top with green onions, extra sour cream, and shredded cheddar.
  • Spicy Kick – Add a pinch of cayenne or red pepper flakes.

Storage & Reheating

  • Refrigerator – Store leftovers in an airtight container for up to 4 days.
  • Freezer – Freeze for up to 2 months (without sour cream topping).
  • Reheat – Warm in the oven at 350°F until heated through for best texture.

  • Holiday dinners like Thanksgiving or Christmas.
