Preheat the oven to 350°F (175°C).
In a large mixing bowl, whisk together the pumpkin puree, heavy cream, brown sugar, eggs, vanilla extract, cinnamon, nutmeg, and salt until smooth and well combined.
Place your ramekins in a baking dish. Carefully pour the pumpkin mixture into each ramekin, filling them about 3/4 full. Pour hot water into the baking dish, around the ramekins, until it reaches halfway up the sides.
Bake in the preheated oven for about 30-35 minutes, or until the filling is set and a knife inserted comes out clean.
Remove the ramekins from the water bath and let them cool at room temperature. Chill in the refrigerator for at least 2 hours, or overnight for best results.
Just before serving, sprinkle a thin layer of granulated sugar over the top of each chilled brulee. Using a kitchen torch, caramelize the sugar until it’s golden and bubbly.
Allow the brûlée to sit for a minute to let the sugar harden before serving. Enjoy the delightful crunch of the topping followed by the creamy pumpkin filling!
