Ingredients

Scale

1 lb boneless chicken breasts or thighs, diced

1 cup orzo pasta

3 large yellow onions, thinly sliced

3 cups beef or chicken broth

1 ½ cups Gruyère or Swiss cheese, shredded

2 tbsp butter

1 tsp fresh thyme or parsley

Salt and pepper to taste

2. Add onions and cook slowly until golden and caramelized (about 20 minutes).

3. Add diced chicken, season with salt and pepper, and cook until lightly browned.

4. Stir in the orzo, coating it with the onion mixture.

5. Pour in broth, bring to a simmer, and cook until most liquid is absorbed.

8. Garnish with thyme or parsley and serve warm.

Notes

This casserole reheats beautifully and can be frozen for up to 2 months. For a vegetarian version, substitute mushrooms for chicken. For extra crunch, top with crispy onions before baking.
