Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Onions: Sweet onions work best for that rich flavor; yellow onions are also great if you prefer a bit more bite.
Butter: Use unsalted butter for better control over the saltiness in your dish.
Heavy Cream: This provides the luscious creaminess that makes this bake so indulgent—don’t skimp on it!
Cheese: Gruyère or Swiss cheese melts beautifully and adds a nutty flavor to balance the sweetness of the onions.
Bread Crumbs: Fresh bread crumbs add a crunchy topping that contrasts nicely with the soft filling.
Fresh Thyme: A sprinkle of fresh thyme elevates the flavor profile with its earthy notes.

Let’s Make it Together
Prepare Your Ingredients: Start by peeling and slicing your onions thinly; aim for about ¼ inch thick so they cook evenly. Gather all your other ingredients for easy access while cooking.
Sauté Those Onions: In a large skillet, melt butter over medium heat until bubbling. Add sliced onions and sauté until they become soft and translucent—about 15 minutes—stirring occasionally to prevent sticking.
Add Cream and Cheese: Once your onions are perfectly caramelized, reduce heat and pour in heavy cream. Stir in half of your cheese until melted and combined, creating that cheesy goodness we all adore.
Assemble Your Bake: Transfer the onion mixture to a greased baking dish, spreading it evenly. Top with remaining cheese and sprinkle breadcrumbs generously across the surface to achieve that heavenly crunch.
Bake Until Golden Brown: Preheat your oven to 375°F (190°C). Bake for about 30-35 minutes until bubbly and golden brown on top—your kitchen will smell divine!
Serve and Enjoy!: Let it cool slightly before serving; this allows flavors to settle. Scoop out generous portions onto plates and prepare for compliments from family and friends as they dive into this savory goodness!
Content: The right onion choice is crucial; sweet varieties caramelize beautifully, enhancing flavor. I learned the hard way after using yellow onions that were too pungent.
Butter cubes need to be evenly cut; this ensures a consistent melt and flavor distribution. I’ve had dry spots before when I rushed this step.
Covering the baking dish with foil locks in moisture, resulting in tender onions. My first attempt was disappointingly firm due to skipping this step.
Perfecting the Cooking Process
Start by sautéing the onions while your oven preheats. This keeps everything on track and maximizes flavor absorption during baking.
