Ingredients (Serves 6):
– 4 large sweet onions, thinly sliced
– 2 tablespoons of unsalted butter
– 2 tablespoons of olive oil
– 2 tablespoons of all-purpose flour
– 1 cup of vegetable broth
– 1 cup of heavy cream
– 1 cup of shredded Gruyere cheese
– 1/2 cup of grated Parmesan cheese
– 1 teaspoon of fresh thyme leaves
– Salt and freshly ground black pepper, to taste
– 1 cup of panko breadcrumbs
– Fresh parsley, chopped (for garnish)


1. Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish for a flawless casserole experience.

2. In a large skillet over medium heat, melt the butter and add the olive oil. Once the butter has melted and the oil is hot, add the thinly sliced sweet onions. Sauté them until they become soft and caramelized, releasing their natural sweetness and adding depth to the dish.

3. Sprinkle the flour over the sautéed onions and stir until the flour is well incorporated. This step will help thicken the sauce and bind the ingredients together.

4. Slowly pour in the vegetable broth and heavy cream, stirring constantly to avoid lumps. Let the mixture simmer for a few minutes until it thickens into a velvety, creamy sauce that envelops the onions in sheer indulgence.

5. Stir in the shredded Gruyere cheese and grated Parmesan cheese, allowing them to melt into the sauce and infuse it with their rich, nutty flavors. The cheese elevates the dish to a whole new level of scrumptiousness.

6. Add the fresh thyme leaves, salt, and freshly ground black pepper, adjusting the seasoning to your taste preferences. Thyme adds a touch of herbaceousness that complements the sweet onions perfectly.

7. Transfer the creamy onion mixture into the greased baking dish, spreading it out evenly to ensure each bite is a delightful balance of flavors.

8. In a separate bowl, combine the panko breadcrumbs with a drizzle of olive oil, mixing until the breadcrumbs are coated. This step will give the casserole a golden, crispy topping that’s simply irresistible.

9. Sprinkle the breadcrumb mixture over the creamy onion layer, creating a tantalizing contrast of textures and adding a lovely crunch to every spoonful.

10. Bake the Sweet Onion Casserole in the preheated oven for 20-25 minutes, or until the top is golden brown and the casserole is bubbling with flavors.

11. Once done, remove the casserole from the oven and let it rest for a few minutes. The aroma that fills your kitchen at this point is simply divine!

12. Garnish with freshly chopped parsley, adding a pop of vibrant color and a hint of freshness to the dish.
