- 1 teaspoon sugar

- 1 cup chicken or vegetable broth
- 1 cup heavy cream
- 1 cup shredded Gruyere cheese (or Swiss cheese)
- 1/2 cup grated Parmesan cheese
- 1/2 cup breadcrumbs
- Fresh parsley for garnish (optional)
Instructions:
- Preheat the Oven: Preheat your oven to 350°F (175°C).
- Caramelize the Onions: In a large skillet, melt the butter and olive oil over medium heat. Add the sliced onions, sugar, salt, and pepper. Cook the onions, stirring occasionally, until they are soft and caramelized, about 15-20 minutes.
- Make the Sauce: Sprinkle the flour over the caramelized onions and stir to combine. Cook for an additional 2-3 minutes to remove the raw flour taste. Gradually whisk in the chicken or vegetable broth, followed by the heavy cream. Continue to cook, stirring constantly, until the mixture thickens.
- Add Cheese: Stir in the shredded Gruyere (or Swiss) cheese and half of the Parmesan cheese until the cheese is melted and the sauce is smooth.
- Assemble the Casserole: Transfer the onion mixture to a greased casserole dish. Sprinkle the remaining Parmesan cheese over the top, followed by a layer of breadcrumbs.
- Bake: Bake in the preheated oven for 25-30 minutes or until the top is golden brown and the casserole is bubbly.
- Garnish and Serve: If desired, garnish the casserole with fresh parsley before serving. Allow it to cool slightly before serving.
This sweet onion casserole makes a delicious side dish for a variety of meals, especially during the holiday season. Enjoy!
