Preheat oven to 350 degrees F. Line 18 (½-cup) muffin cups with paper liners.
Whisk applesauce, sugar and oil in a large bowl. Add flour, baking soda and salt; whisk until combined. Gently fold in strawberries. Divide the batter among the prepared muffin cups.
Bake the muffins until the tops spring back when touched lightly and a toothpick inserted in the center comes out clean, 22 to 28 minutes. Let cool in the pan for 5 minutes, then turn out onto a wire rack to cool completely.
