✔ ½ tsp freshly ground black pepper
✔ 1 tsp dried tarragon
✔ 1 tsp dried thyme
✔ ⅓ cup brandy or dry white wine

✔ 1 cup heavy cream
✔ 3–4 cups cooked chicken, chopped (rotisserie is perfect!)

🔪 Instructions

1️⃣ Caramelize the Onions

In a large skillet, melt 1½ tbsp butter and heat 1½ tbsp olive oil over medium-low. Add sliced onions and cook for 30–45 minutes, stirring occasionally, until deeply golden and caramelized.

2️⃣ Flavor It Up

Add garlic, salt, pepper, tarragon, and thyme to the onions. Stir for 1 minute.
Remove from heat, pour in brandy or wine, and return to heat to let the liquid cook off. Stir in Worcestershire sauce, then set mixture aside.

3️⃣ Cook the Mushrooms & Rice

In a dry pan, sauté mushrooms until browned (5–10 mins).
Add remaining 1½ tbsp butter and 1½ tbsp olive oil, then stir in rice. Cook for 5 minutes, stirring occasionally.

4️⃣ Wilt the Spinach & Simmer

Add spinach, cook for 1 minute until wilted.
Pour in chicken stock, bring to a simmer, cover, and let it cook for 15 minutes until rice is tender.

5️⃣ Creamy Chicken Time

Remove pan from heat. Stir in heavy cream and chopped chicken until well combined.

6️⃣ Assemble the Casserole

Preheat broiler. Transfer rice mixture to a greased 9×13-inch baking dish.
Top evenly with the caramelized onion mixture and sprinkle with Gruyère cheese.

7️⃣ Broil & Serve

Broil for 2–4 minutes, or until the cheese is bubbly, melted, and golden on top.
Serve hot and savor every creamy, cozy bite!

Wine-Free Option: Use a splash of chicken stock + 1 tsp vinegar instead of brandy or wine.
