I love lemon bars because they are delightfully sweet and tangy! Perfect for any gathering, they bring a bright happy pop of color to any spread.
This recipe for lemon bars is quick and turns out every time. Pre-baking the crust makes sure it is tender and perfectly golden prior to adding the lemon layer. Most recipes for lemon bars that you’ll find on the internet have a very thin layer of lemon but these have a substantial lemon curd that can stand on its own.

Best Lemon Squares Recipe FAQs
A crust on a lemon bar is completely normal! This comes from the air rising to the surface.
This all depends on your personal taste. I typically bake these in a glass pan, but a metal pan works as well.
In most situations, if lemon bars have a slightly eggy taste, it is because they were overcooked. Make sure you only bake until the lemon layer has just set and is no longer runny.
You can leave lemon bars on the counter for up to 24 hours. Then they are best stored in the fridge.
There are a couple of things that can impact the integrity of your lemon bars. The first is if your crust has cracks in it and the lemon curd fills in the cracks. This can cause your lemon bar to break! It may also break if you don’t bake the crust long enough or the lemon layer is underbaked.
Your lemon bars may be mushy if the crust is not baked enough before adding in the lemon layer to bake.
Make sure you allow your lemon bars to completely set before you cut them. This will keep them from spreading and becoming sticky.
Results may vary, but it’s worth a shot! Throw them back in the oven at the original temperature and rotate every 5 minutes until it appears done.
What to serve with Lemon Bars
These are the perfect party dessert but are pretty sweet and tangy. I find it best to serve it with an assortment of salty snacks and mild beverages.
