Ingredients for the Crust
You will want to use fresh lemons for this recipe, not lemon juice concentrate. But if it’s all you have, see below for how to use it. It will not give you the best flavor, however.

- Flour: You will divide the flour.
Lemon Filling Ingredients

- Sugar: Brings the sweetness to counterbalance the tartness from the lemons.

All About Lemons!
Lemons are the star of this dessert. You want it to be divine, so picking and using your lemons matters. When your lemons are perfect, it can really brighten any dish. Some of my best recipes contain lemons as the main ingredient. Try one of these favorites like this Scallops , Chicken, or Fettuccine.
- How do I pick a good Lemon? It can seem complicated, but when you know what to look for, you’ll be an expert. Look for lemons that seem heavy when you hold it in your hands. Also look for thin skin, that is firm and has a fine texture to the peel. It should be a deep yellow color. The heavier the fruit and thinner the skin the more juice it will have.
- Where should I store Lemons? It is so tempting to decorate your counter with fresh fruit in a pretty bowl. Just leave the lemons out. If left at room temperature the skins can become tough and the lemons can actually dry out. Keep your lemons in the fridge.
- Zesting Lemons: Wash your lemons thoroughly before zesting. If you don’t have a zester you can use the smallest holes of a cheese grater. You want to stop zesting once you hit the pith or white part as it is quite bitter.
- Juicing Tip: Cut and quarter your lemons and then microwave them for about 30 seconds. This helps the lemons release more of its juice.
- Can I use bottled lemon juice instead of lemons? You can but it will definitely change the flavor a bit. I always prefer fresh. When substituting lemon concentrate for real lemon juice in a recipe, use two tablespoons of bottled lemon juice to replace the juice of one lemon. Substitute lemon juice concentrate for equal proportions in any recipe calling for lemon juice.
Tips for the Best Lemon Bars
The tartness of these lemon bars is perfectly controlled by the powdered sugar. Just don’t inhale when you take a bite, speaking from experience, airways full of powdered sugar is no fun.
- Cool: It is best to let your bars cool at room temperature for at least two hours.
- Room Temperature: Use room temperature eggs and butter. They mix up easier and better.
- Line the Pan: If you are worried about the lemon bars not being able to come out, use foil or parchment paper in the bottom.
- Sift: Use a sifter or sieve to spread the powdered sugar on top of the bars. It will cover them evenly and without lumps
- Store: You can keep these at room temperature, however the flavor improves when they are refrigerated.
