In a Dutch oven melt half of the butter over medium heat
Add mushrooms and shallots and saute until tender, about 8 minutes.
Add garlic, thyme (strip the leaves off), salt and pepper and stir for an additional minute. Remove mushroom mixture from pan and set aside.
Add remaining butter to pan over medium heat.
Once butter has melted, add rice and stir until rice begins to look translucent, 3-4 minutes but up to 10 minutes.
Add ¾ cup dry white wine and lemon juice and bring to a simmer, stirring constantly until liquid is mostly absorbed.
Add 1 cup of broth and stir until almost all broth is absorbed.
Continuing adding broth 1 cup at a time, and stir until liquid is almost absorbed. (This step takes 20 or so minutes but is absolutely worth the effort!)
Add mushroom mixture into the rice and stir to combine.
Gently stir in heavy cream and parmesan cheese and cook until well incorporated on low heat.
Risotto should be creamy, but still have a bite/firmness about it. Add extra parm for smiling faces.
