In a large skillet over medium heat, melt butter.
Stir in your minced garlic.
Once your garlic starts to caramelize, pour in heavy cream.
When the heavy cream comes to a light simmer, slowly start to stir in shredded parmesan. (I recommend a 1/4 cup at a time to ensure that the cheese melts properly.
Once the cheese has melted, stir in crushed tomatoes, lemon juice, salt and pepper.
Simmer on low for 10 minutes, then use in your favorite dish.
