How to Make French Onion Potato Bake
Follow these simple steps to prepare this delicious French Onion Potato Bake:
Step 1: Preheat Your Oven
Preheat your oven to 375°F (190°C). A hot oven is key to achieving a bubbly, golden top on your potato bake.
Step 2: Caramelize the Onions
In a large skillet over medium-low heat, melt the butter with olive oil. Add the sliced onions and a sprinkle of salt. Cook slowly for about 30 minutes, stirring occasionally, until the onions turn a gorgeous golden brown and are caramelized to perfection.
Step 3: Add Flavors
Stir in garlic powder, thyme, and beef broth into the skillet with the onions. Allow this savory mixture to simmer for a few minutes, letting the flavors meld together.
Step 4: Layer the Ingredients
In a greased 9×13-inch baking dish, layer half of the potato slices at the bottom. Sprinkle with salt and pepper, then cover with half of the caramelized onion mixture, followed by a third of the Gruyère cheese.
Step 5: Repeat the Layers
Repeat the layering process with the remaining potatoes, followed by the rest of the onions and Gruyère cheese. This creates a delightful mixture of flavors and textures in every layer.
Step 6: Add the Creamy Mixture
In a separate bowl, whisk together the heavy cream, salt, and pepper. Pour this cream mixture over the layered bake, ensuring that all the potatoes are well coated.
Step 7: Bake and Serve
Cover the baking dish with aluminum foil and bake for 45 minutes. After that, remove the foil, sprinkle on the Parmesan cheese and optional crispy fried onions, and bake uncovered for an additional 20-30 minutes until the top is golden and bubbly. Bake until the room fills with the irresistible aroma of cooked onions and melted cheese, pulling everyone to the kitchen.
