Ingredients in Lemon Bars From Scratch

Lemon Filling

  • Lemon Juice – Make sure to use fresh lemon juice for the best lemon flavor.
  • Zest from Lemons – it’s best to zest the lemons before cutting and juicing them.  You’ll need zest from about 3-4 lemons for a single batch of this recipe.
  • Sugar – this recipe calls for white granulated sugar.
  • Flour – all-purpose flour works great.  It helps to bind the custard together.
  • Eggs – any type of large eggs will work well.

Shortbread Crust For Lemon Bars

  • Flour – we use all-purpose flour for this shortbread crust.
  • Sugar – you’ll need white granulated sugar for the crust.
  • Salt – either sea salt or kosher salt.
  • Butter – you’ll want your butter to be room temperature so that you can cut it into the dry ingredients more easily.

How to Make Lemon Bars with Shortbread Crust

  1. Prepare your baking dish.  Spray a 9″ x 9″ baking dish with nonstick cooking spray, then line the inside with parchment paper.  Make sure the parchment paper overlaps the edges so they can be easily lifted.  Set aside.
  2. Prepare the Lemon Filling.  To make the lemon filling, combine the lemon juice, lemon zest, sugar, flour and eggs in a large bowl and whisk to combine.  Set aside while you make the crust.
  3. Make the Shortbread Crust.  In a separate large mixing bowl, combine the flour, sugar and salt and whisk together.  Add the room temperature butter and mix with a pastry cutter (or your fingers) until the mixture is combined and slightly crumbly.  Pat the shortbread dough into the bottom of the prepared baking dish.
  4. Bake the crust.  In a preheated 350 degree oven, bake for about 12 minutes until set, then remove from the oven.
  5. Bake the lemon filling with the crust.  Whisk the lemon custard filling gently, making sure there aren’t any lumps, then pour on top of the baked crust.   Place the baking dish back into the oven and bake for an additional 20 minutes, or until the lemon custard is set and the edges of the lemon bars are light golden brown.
  6. Cool.  Remove the shortbread lemon bars from the oven and let them cool completely. Once cooled, lift them out of the pan using the edges of the parchment paper and dust with powdered confectioner sugar.  Cut into squares and enjoy!

Tips and Tricks

  • For best results, mix the filling before making the crust so that it will have time to rest.   This will help to prevent bubbles from forming on top of the lemon curd bars, and also give the flour a chance to hydrate more before baking.
  • Greasing the Pan– To ensure easy removal of the lemon bars, grease the baking pan with butter or cooking spray before adding the shortbread crust. This will prevent sticking and help maintain the shape of the bars.
  • I like to use a couple of pieces of parchment paper on the bottom of the baking dish- one for the length and one for the width.  This allows you to pull the lemon squares by the edges of the parchment paper after they’ve baked and cooled.
  • Dusting with Powdered Sugar– Before serving, dust the top of the lemon bars with powdered sugar for a professional finish. This not only adds a touch of sweetness but also enhances the visual appeal of your homemade treats.
  • To get the best lemon flavor, always use fresh lemon juice!  
  • For a fun switch-up, use fresh lime juice or a combination of lemon and lime to make citrus bars.
  • You can make the shortbread crust in an electric mixer if you’d like.  Add all ingredients and mix on low speed using the paddle attachment until crumbly.

Frequently Asked Questions

How do I know when my Lemon Bars are done baking?

The bake time given is just a suggestion and may vary but a minute or two.  You will know your Lemon Bars are done when you lightly jiggle the pan and the custard isn’t runny.  The edges should also be lightly browned. 

Do Lemon Bars need to be refrigerated?

Yes – they can sit out at room temperature for up to 1 hour and then they should be refrigerated.  They can be stored in the fridge for up to 1 week.

Can you freeze Lemon Bars?

Yes!  Make sure they are completely set up and cut into squares, place the entire baking dish into the freezer for about 30 minutes, then remove and wrap each lemon bar in aluminum foil.  Transfer to a freezer bag and store for up to 2 months frozen. 

Why do my Lemon Bars taste eggy?

Most likely, if your Lemon Bars have an eggy taste to them it is because they were overcooked.  Make sure and bake only until the custard has set and it is no longer runny.

  1. Greta recipe! At first, when I clicked the link, a different video popped up with different measurements… but once I found the right video, the recipe was easy to follow!

  2. came out perfect. recipe is spot on. I added another half recipe to the crust and baked an additional 5 minutes before adding the custard filling. My family loved it. This one is a keeper

  3. After 12 minutes at 350 the shortbread was no where near set so I put it back in for an additional 3 minutes. It still didn’t look totally solid but I decided to trust the recipe since otherwise I followed it to the letter. The lemon filling went right through the shortbread and created a mess. Flavors were good but bake time need to be corrected!
