To Prepare the Warm Mushroom Salad
In a large bowl, toss mushrooms with just enough of the olive oil to moisten them, then add the rosemary and lemon zest. Allow to rest for 1⁄2 hour.
After the 1⁄2 hour, heat a medium sauté pan and add the remainder of the olive oil and the garlic and shallots; season with salt and pepper and lightly sauté for about a minute.
Add the mushrooms and turn the heat up to high and cook quickly for 2 minutes to wilt the mushrooms. Season with salt and pepper, stir in the parsley and remove from heat.
To Prepare the Mascarpone Polenta
Bring the cream and chicken stock to boil in a medium saucepan. Season liberally with salt and pepper and reduce to a simmer. Slowly, whisking constantly, add the polenta to the simmering liquid. Allow to simmer 2 additional minutes, then remove from the heat. Mix in the mascarpone and Parmesan cheeses, then cover.
Taste all the components for seasonings and adjust, if necessary. Place a generous spoonful of the polenta on each plate and top with half of a round of burrata. Spoon the warm mushroom salad over the burrata. Finish with a drizzle of extra-virgin olive oil and a sprinkle of Parmesan cheese.
