Nothing beats a good key lime pie, and our readers have given this recipe 5 stars. It's a lighter version due to the fat-free sweetened condensed milk and frozen reduced-calorie whipped topping, but it tastes just as rich and fresh. You'll never know the difference.

How to Make It

Step 1

Preheat oven to 350°.

Step 2

Beat eggs and egg whites at medium speed of a mixer until well-blended. Gradually add juice, rind, and milk to egg mixture, beating until well-blended. Spoon mixture into crust, and bake at 350° for 20 minutes or until almost set (the center will not be firm but will set up as it chills). Cool pie on a wire rack. Cover loosely, and chill 4 hours. Spread whipped topping evenly over filling.

Super easy and really good! I used fresh key limes because I already had them, but they didn't yield quite enough juice. I added a bit more zest to make up for it. Excellent!

So easy and delicious! Used about 30 small key limes off our tree (they're about half the size you'd buy in store). Served pieces garnished with thin slices of lime.

Like everyone else has said: quick, easy, and amazing! Definitely a frequently-requested favorite, especially in the summer. I make my own graham cracker crust with Cooking Light's recipe and it's easy and very tasty as well.

I made this for a labor day BBQ with friends and I was so proud of the results! I second the other reviewers comments about never knowing it was a light recipe. Usually when I make a pie the pieces fall apart, but this sliced so nicely and looked very professional when dished out. I will only make this key lime pie recipe from now on!

This pie is divine! It's very fresh and flavorful, does not taste at all like it is low in fat. I will make this pie again and again. So good and extremely easy to make. Will use homemade whipped cream next time instead of cool whip.

This recipe is soooo simple and the results are wonderful. People cannot believe it is a cooking light recipe when they taste it. I have made this so many times and it is always a hit!
