Mini Blueberry-Lemon Cheesecakes

Preheat oven to 325 degrees F. Line 24 (1/2-cup) muffin cups with paper liners or coat with cooking spray.

Combine graham cracker crumbs and oil in a small bowl. Press about 2 teaspoons in the bottom of each muffin cup.

Beat ricotta in a large mixing bowl with an electric mixer until smooth. Add cream cheese, eggs, sugar, lemon zest and juice, vanilla and salt; beat until smooth. Fold in 1 cup blueberries. Spoon about 1/4 cup cheesecake batter into each muffin cup. Sprinkle each cheesecake with some of the remaining blueberries.

Bake the cheesecakes until almost set in the center, 32 to 35 minutes. Let cool in the tin on a wire rack until room temperature, about 1 hour. Loosely cover with plastic wrap and refrigerate until cold, at least 2 hours and up to 1 day.
