Ingredients to make Classic Lemon Bars
Let’s start by gathering the ingredients we need to make my Classic Lemon Bars recipe. In Chef Speak, this is called the Mise en Place, which translates into Everything in its Place.
Not only does setting your ingredients up ahead of time speed the cooking process, but it also helps ensure you have everything you need to make the dish.
Should I use fresh lemon juice or bottled lemon juice?
While fresh lemon juice is preferred for the best flavor, you can use bottled lemon juice as a substitute if fresh lemons are not available. Just make sure it’s 100% pure lemon juice without any added sweeteners or preservatives.
*You’ll need fresh lemons for the lemon zest, so you might as well use fresh juice.
You can also use Meyer lemons to make my homemade lemon bars.

*or the bowl of a stand mixer, fitted with the paddle attachment. - Whisk to combine.

- Place the pan on the center rack of the preheated oven and bake for about 20 minutes or until it’s a light golden brown color.
Remove the pan from the oven and let it cool on a wire rack for a few minutes. The crust should still be a little warm when you add the filling.
