Instructions

  1. Step 1: In a medium saucepan, bring 4 cups water and 1 tsp salt to a boil over medium-high heat.
  2. Step 2: Gradually whisk in 1 cup coarse cornmeal, reducing heat to low. Stir constantly with a wooden spoon for 25-30 minutes until the polenta thickens and becomes creamy.

  5. Step 5: Add 2 cloves minced garlic and 1 tsp fresh thyme leaves to the mushrooms, cooking for 1 more minute until fragrant.
  6. Step 6: Season mushroom mixture with 1/4 tsp black pepper, then stir into the creamy polenta.
  7. Step 7: Garnish with 2 tbsp chopped fresh parsley before serving warm.
