Reduce the oven temperature to 325°F and position two racks—one in the middle and one on the lowest level. Start heating 3 cups of water in the microwave; you’ll need it when it's time to bake.
In a large mixing bowl or the bowl of a stand mixer fitted with a paddle attachment, beat the cream cheese, sugar, salt, and vanilla on medium-high speed until very smooth, about 2 minutes. Scrape the bowl 1-2 times as needed during this step.
32 oz full fat, brick cream cheese, 1¼ cup granulated sugar, ½ teaspoon kosher salt, 1 tablespoon vanilla
Add the eggs one at a time and mix on low speed, mixing until each is well combined before adding the next one. Scrape the bowl occasionally.
3 large eggs
Add the heavy cream and lemon juice on low until just combined. Pour the filling into the cooled crust and place the pan on a rimmed cookie sheet.
⅓ cup heavy cream , 2 tablespoon lemon juice
Moving quickly, place the cookie sheet on the middle rack. Then place a large roasting pan on the bottom rack and pour in the hot water. Close the door to the oven quickly to trap the steam.
Bake at 325°F for 55 minutes. Then turn the oven off and prop the oven door slightly (I used a wooden spoon) and let it cool for 1 hour. Don't open the oven all the way or the heat will escape and it won't finish cooking.
After an hour, remove the cheesecake from the oven and cool for 3-4 hours at room temperature, then refrigerate overnight or until fully chilled. Once it is completely chilled, remove it from the springform pan and serve.
