Preheat your oven to 350°F (175°C). Lightly grease a 9-inch round baking pan with cooking spray and line the bottom with a round piece of parchment paper. This helps to prevent sticking and makes releasing the dessert easier later.

Peel, core, and slice the pears into even pieces. Arrange the sliced pears neatly in the bottom of the prepared baking pan, spreading them out to form an even layer.

In a blender, combine the melted butter, eggs, milk, kosher salt, sugar, all-purpose flour, and vanilla extract. Blend everything together until the mixture is completely smooth, forming a custard-like batter. I like to use room-temperature eggs for a silkier custard.

Pour the smooth custard batter gently over the arranged pear slices in the baking pan. Place the pan in the oven and bake for 40 to 45 minutes, or until the top is golden brown and the center is set and firm to the touch. To test doneness, gently shake the pan—the center should not wobble excessively.

Let the clafoutis cool slightly before slicing. Dust with powdered sugar if desired, and serve slices with strong coffee for a delightful experience. I always enjoy pairing it with coffee to enhance the flavors.
