Ingredients

Instructions

  1. Step 1: Finely dice 1 medium onion and mince 2 garlic cloves; heat 1 tbsp olive oil in a heavy pot over medium heat until shimmering, then sauté onions until translucent (5 minutes), adding garlic in the last minute until fragrant.
  2. Step 2: Add 1 ½ cups Arborio rice to the pot and stir constantly for 2 minutes until rice grains are coated and slightly translucent.
  3. Step 3: Pour in ½ cup dry white wine and stir until fully absorbed, about 2 minutes until liquid evaporates and rice smells nutty.
  4. Step 4: Add 4 cups warm vegetable stock, one ladle at a time (about ½ cup per addition), stirring constantly until each portion is absorbed before adding more, maintaining a gentle simmer for 20-25 minutes until rice is creamy but still slightly firm.
  5. Step 5: While rice cooks, slice 8 oz cremini mushrooms and sauté in 2 tbsp butter over medium-high heat until golden brown and crispy (6-8 minutes), then stir in 3 tbsp fresh thyme leaves.
  6. Step 6: Once rice is cooked, fold in the mushroom mixture, ½ cup grated Parmesan, and remaining 1 tbsp butter until fully melted and glossy, tasting to adjust salt if needed.
  7. Step 7: Let rest for 3 minutes off heat to thicken, then serve immediately with extra thyme for garnish.
