Ingredient Checklist


Instructions Checklist
  • In a large skillet, heat vegetable oil over medium-high heat. Add onion, carrot, and celery; season with salt and pepper; cook, stirring occasionally, until vegetables begin to soften, about 5 minutes.

  • Add garlic and cook for 1 minute. Add mushrooms and thyme leaves; cook, stirring frequently, until mushrooms are almost tender, about 3 minutes. Add tomato and cook, about 2 minutes more.

  • Add stock to skillet, 2 tablespoons at a time, bringing liquid to a simmer before each addition. Simmer until thickened, about 30 minutes. Remove from heat and set mushroom bolognese aside to cool.

  • In a medium bowl, mix polenta with 2 tablespoons water to moisten. Bring 4 cups water to a boil in a medium saucepan over high heat. Add a pinch of salt to boiling water and slowly stir in polenta. Bring to a boil, stirring constantly, and immediately reduce to a simmer. Cook polenta, stirring occasionally, until no longer grainy, about 30 minutes. Remove from heat; stir in olive oil and season with salt.

  • Preheat oven to 350 degrees. Spoon half of the polenta into a medium baking dish and cover with reserved mushroom bolognese. Top with remaining polenta and sprinkle with Parmigiano Reggiano.

  • Transfer baking dish to oven and bake until top is golden, about 40 minutes. Serve immediately.
