For the Orzo Base

• 1 tsp fresh thyme (or ½ tsp dried thyme)
• 1 tsp garlic powder

Step-by-Step Instructions

1 – Caramelize the Onions

Heat butter and olive oil in a large oven-safe skillet over medium-low heat.
Add sliced onions and sugar. Cook slowly for 25–30 minutes, stirring occasionally, until deep golden brown. Season with salt and pepper.

2 – Add Broth & Orzo

Once onions are caramelized, add orzo, thyme, balsamic vinegar, garlic powder, and beef broth.
Stir and bring to a simmer. Cook uncovered for 8–10 minutes, stirring occasionally, until the orzo begins to absorb the liquid.

3 – Stir in Cream & Cheese

Reduce heat to low. Add heavy cream, half of the Gruyère, and mozzarella. Stir until melted and creamy.

4 – Bake Until Golden

Top with the remaining cheese and Parmesan.
Transfer skillet to a preheated oven at 375°F (190°C).
Bake for 15–20 minutes or until bubbly and golden on top.

5 – Serve Hot

Let cool for 5 minutes before serving.
Garnish with fresh thyme and a sprinkle of extra cheese.
