Essential Ingredients

Here’s what you’ll need to make this delicious dish:

Potatoes: Choose starchy potatoes like russets for a fluffy texture that absorbs all the delicious flavors.
Onions: Yellow onions are perfect here; they caramelize beautifully and provide that sweet savory depth.
Cheese: A mix of Gruyère and mozzarella gives a gooey texture and rich flavor that’s hard to resist.
Butter: Use unsalted butter for sautéing; it allows better control over the overall saltiness of your dish.
Thyme: Fresh thyme adds an aromatic touch that complements the sweetness of the onions perfectly.
Heavy Cream: For richness, heavy cream binds everything together into a luxurious bake.
Salt and Pepper: Essential for seasoning; adjust according to your taste preferences.

Let’s Make it together

First things first: Prep your workspace and gather all ingredients so you’re ready to rock this recipe like a pro.

Preheat Your Oven: Start by preheating your oven to 375°F (190°C). Trust me; this step is crucial for achieving that golden-brown crust we all crave.

Sauté Those Onions: Melt 3 tablespoons of butter in a skillet over medium heat. Add thinly sliced onions and cook until soft and caramelized—it takes about 15 minutes. Inhale deeply; this is where the magic begins!

Slice Your Potatoes: While those onions work their magic, wash and thinly slice your potatoes using a mandoline or sharp knife. Aim for uniform thickness—about 1/8 inch works wonders.

Mix It Up!: In a large bowl, combine the sautéed onions with heavy cream, thyme leaves, salt, and pepper. Stir until everything is well incorporated. You’re almost there!

Layer It Up!: In a greased baking dish, layer half of the potato slices evenly across the bottom. Top with half of the onion mixture followed by half of the cheese mix. Repeat these layers until you’ve used everything up.

Bake It Perfectly!: Cover your dish with aluminum foil and bake for 40 minutes. Remove foil and bake for an additional 20 minutes until bubbly and golden brown on top—your kitchen will smell heavenly!

Now you have created an irresistible Savory French Onion Potato Bake that will surely become a family favorite!
