This Lime Jello Salad is an old-fashioned favorite made with lime Jell-O, cream cheese, crushed pineapple, and Cool Whip. It’s creamy, fruity, and firm enough to cut into pretty slices, which makes it perfect for holidays, potlucks, and Sunday dinner.
Pour the crushed pineapple into a fine-mesh strainer set over a bowl. Press gently to remove as much juice as possible. Measure ½ cup of the pineapple juice and set aside. Keep the drained pineapple for later.
Add the lime Jell-O powder to a small mixing bowl. Pour in 1 cup boiling water and stir for about 2 minutes, or until the gelatin is completely dissolved.
Stir in the reserved ½ cup pineapple juice. Let the mixture cool for about 15 minutes, or until it is no longer warm.
In a separate large bowl, beat the softened cream cheese with an electric mixer until completely smooth and creamy.
With the mixer on low, gradually pour the cooled Jell-O mixture into the cream cheese, a little at a time, beating until smooth. Refrigerate for 20-30 minutes, or until the mixture is cool and just beginning to thicken. Don't let it set.
Gently fold in the Cool Whip until evenly combined. Fold in the drained crushed pineapple.
Spread the mixture evenly into a lightly greased 9x9-inch baking dish. Cover and refrigerate for at least 6 hours, preferably overnight, until completely set.
Cut into squares with a sharp knife. For especially clean slices, wipe the knife clean between each cut. Keep refrigerated until ready to serve. Optional to top with whipped cream.
Notes
Keep the Jell-O salad tightly covered in the refrigerator until you are ready to serve. Leftovers are best within about 3 days. I don't recommend freezing because the gelatin, cream cheese, and Cool Whip can separate and become watery once thawed.
