Step‑by‑Step Instructions for French Onion Soup Potatoes

Step 1: Caramelize the Onions
In a large skillet, melt 2 tablespoons of butter and 1 tablespoon of olive oil over medium heat. Add 3 thinly sliced large yellow onions and cook for about 25–30 minutes. Stir frequently until the onions are deep amber in color and have a jam-like consistency. This step is crucial for building that sweet flavor foundation in your French Onion Soup Potatoes.

Step 2: Prepare Potato Layers
While the onions are caramelizing, slice 2 pounds of Yukon Gold potatoes into ¼-inch thick rounds for even cooking. Pat the potato slices dry with paper towels to remove excess moisture, ensuring they achieve a creamy texture and a lovely golden finish later on. Set these aside while the onions finish cooking.

Step 3: Combine Liquid Ingredients
In a medium mixing bowl, whisk together 2 cups of beef broth, 1 cup of heavy cream, 1 tablespoon of Worcestershire sauce, and 1 teaspoon of fresh thyme. Season with salt and black pepper to taste. This rich mixture will create the luscious sauce that brings the French Onion Soup Potatoes together seamlessly.

Step 4: Layer the Ingredients
Preheat your oven to 350°F (175°C). In a greased baking dish, start layering the sliced potatoes, followed by the caramelized onions, and a mix of 1 cup shredded Gruyère cheese and ½ cup grated Parmesan cheese. Repeat the layers until you’ve used all the ingredients, finishing with a layer of potatoes on top. Drizzle the prepared liquid mixture evenly over everything.

Step 5: Bake
Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 45 minutes. This allows the potatoes to tenderize beautifully. After 45 minutes, remove the foil and bake for an additional 20–30 minutes, until the top is golden, bubbly, and the edges are slightly crispy—a delightful contrast to the creamy layers below.

Step 6: Rest and Serve
Once baked, remove the French Onion Soup Potatoes from the oven and let them rest for about 10 minutes before serving. This resting time not only enhances the flavors but ensures that the dish holds together nicely when served. Enjoy this comforting side that epitomizes the warmth of home cooking!
