Description

Savory french onion potato bake combines classic French flavors with hearty comfort. Rich layers of caramelized onions, creamy potatoes, and melted gruyère cheese promise a delicious meal you’ll crave again and again.


Ingredients

Scale

Main Ingredients:

  • 6 medium potatoes, thinly sliced (1/8 inch thick)
  • 2 cans (10.5 ounces / 298 grams each) french onion soup
  • 1 cup (240 milliliters) heavy cream
  • 2 cups (226 grams) shredded Gruyere cheese
  • 1 cup (50 grams) crispy fried onions

Herbs and Seasonings:

  • 2 tablespoons fresh thyme
  • Salt to taste
  • Black pepper to taste

Instructions

  1. Arrange the potato slices in a uniform base layer within a greased 9×13-inch baking dish, creating a foundation for the potato bake.
  2. Generously sprinkle salt and freshly ground black pepper across the initial potato layer, ensuring even seasoning throughout.
  3. Gently pour half the condensed cream soup and cream over the seasoned potatoes, allowing the liquid to seep between the potato slices.
  4. Create a second layer of potato slices directly atop the first, overlapping slightly for a consistent texture.
  5. Distribute the remaining cream soup and cream evenly across the top potato layer, ensuring complete coverage.
  6. Liberally scatter grated Gruyere cheese and fresh thyme leaves over the entire surface, creating a rich and aromatic topping.
  7. Cover the baking dish with aluminum foil, creating a sealed environment for initial cooking at 375°F (190°C) for 45 minutes.
  8. Remove the foil and sprinkle crispy onions across the top, returning the dish to the oven for an additional 15 minutes until the surface turns golden brown and crisp.
  9. Remove from oven and let rest for 5-10 minutes before serving to allow the layers to set and flavors to meld together.

Notes

  • Boost Flavor by caramelizing onions before adding to the dish for deeper, richer taste that elevates the entire potato bake.
  • Cheese Selection matters: substitute Gruyere with sharp cheddar or gouda if unavailable, ensuring similar melting qualities and rich flavor profile.
  • Dietary Adaptation easily converts this recipe to gluten-free by using cornstarch-thickened cream and gluten-free cream of mushroom soup.
  • Texture Optimization comes from slicing potatoes uniformly and using a mandoline for consistent, thin cuts that ensure even cooking and crispy edges.
