Combine lemon juice with cornstarch and stir into mixture and simmer an additional minute until thickened. Place strawberry mixture in food processor and pulse until smooth. Place in a bowl and set aside.
Pour half of the strawberry sauce on top of cheesecake. Use remaining sauce however you wish, I like adding it to lemonade, yum! Bake at 325 degrees for 36 minutes or until cheesecake is just slightly jiggly.
