Instructions

  1. Step 1: Melt 1 tbsp butter in a large skillet over medium-low heat. Add finely chopped onion and cook slowly for 25 minutes, stirring occasionally, until deeply golden brown and caramelized — this step is essential for rich flavor.
  2. Step 2: Melt remaining 1 tbsp butter in a medium pot over medium heat. Add sliced mushrooms and cook for 5 minutes until they release moisture and turn golden. Pour in white wine and simmer for 2 minutes until alcohol evaporates.
  3. Step 3: Add Arborio rice to the pot, stirring to coat. Cook for 1 minute, then add 1 cup hot broth. Stir constantly until broth is absorbed, then repeat with remaining broth in 1-cup increments (about 18-20 minutes total).
  4. Step 4: Stir in caramelized onions, thyme, salt, and pepper. Remove from heat, then stir in grated Parmesan until melted and creamy. Adjust seasoning and serve immediately.
