Preheat the oven to 375 degrees F. Lightly butter 6 (6-ounce) ramekins.
Whisk the oats, flour, brown sugar, pecans, and salt in a medium bowl. Rub in the butter with your fingertips until it is in even, pea-size pieces. Peel, core, and coarsely chop the apples and divide evenly among the ramekins. Scatter the crisp topping evenly over the fruit in each ramekin.
Transfer the ramekins to a baking sheet and cook until the fruit bubbles around the sides and the top is golden, about 30 minutes.
Preheat a broiler. Place the crisps about 4 inches from the broiler and cook until golden brown, about 30 seconds. Let cool about 15 minutes before serving. Serve warm with whipped cream, if using.
