Step 1: In a medium bowl, combine the graham cracker crumbs, granulated sugar, and melted butter. Mix until well combined and the crumbs are moistened.
Step 2: Press the mixture firmly into the bottom of a 9x13-inch baking dish. Refrigerate for at least 15-20 minutes to firm up the crust.
Step 3: In a large mixing bowl, beat the softened cream cheese and powdered sugar with an electric mixer on medium speed until smooth and creamy, about 2-3 minutes.
Step 4: Add the whipped topping to the cream cheese mixture. Gently fold it in with a spatula until just combined.
Step 5: Evenly spread the cream cheese mixture over the cooled graham cracker crust. Place the dish in the refrigerator to chill for at least 30 minutes.
Step 6: In a separate bowl, whisk together the strawberry Jell-O mix and 2 cups of boiling water until the Jell-O powder is completely dissolved. Stir for about 2 minutes.
Step 7: Add 2 cups of cold water to the dissolved Jell-O mixture. Stir well and let it cool down to room temperature. This is crucial; the Jell-O must be cool but still liquid.
Step 8: While the Jell-O cools, arrange a layer of fresh, sliced strawberries over the cream cheese layer in your dish.
Step 9: Carefully pour the cooled Jell-O mixture over the strawberries and cream cheese layer. Pour slowly over the back of a spoon to prevent disturbing the layers.
Step 10: Return the dish to the refrigerator and chill for at least 4-6 hours, or preferably overnight, until the Jell-O is completely set and firm.
Step 11: Once set, slice into squares and garnish with extra whipped cream and strawberries if desired before serving. Enjoy your delicious no bake strawberry jello lasagna recipe!
