Prep Time, Cook Time, and Total Time
Prep Time: 15 minutes
Cook Time: 25 minutes
Total Time: 40 minutes
Servings: 12 lemon bars
Ingredients
- 1 cup all-purpose flour
- 1/2 cup unsalted butter, melted
- 2 large eggs
- 1 cup granulated sugar
- 1/4 cup fresh lemon juice
Instructions
- Preheat your oven: Begin by preheating your oven to 350°F (175°C).
- Prepare the crust: In a mixing bowl, combine the melted butter, flour, and half of the sugar (1/2 cup). Mix until crumbly. Press the mixture into the bottom of an 8×8 inch baking dish to form an even layer for the crust.
- Bake the crust: Place the baking dish in the preheated oven and bake the crust for 15 minutes, or until lightly golden. Remove from the oven and set aside to cool slightly.
- Make the filling: In a separate bowl, whisk together the eggs, remaining half of the sugar (1/2 cup), and lemon juice until smooth and well combined.
- Add the filling: Pour the lemon filling over the baked crust, spreading it evenly.
- Bake again: Return the dish to the oven and bake for an additional 20 minutes, or until the filling is set. It should not jiggle when you shake the dish gently.
- Cool and serve: Allow the bars to cool completely in the baking dish before cutting them into squares. Dust with powdered sugar if desired.
Pro Tips for Perfect Results
- Using fresh lemon juice enhances the flavor; bottled lemon juice may not yield the same fresh taste.
- For cleaner cuts, pop the bars in the fridge for an hour before slicing them.
- Always let the bars cool completely to ensure the filling sets properly.
- Add a touch of lemon zest to the filling for an extra burst of flavor.
- Store any leftover lemon bars in an airtight container to maintain freshness.
Variations and Substitutions
Feel free to experiment with this classic recipe. You can use almond flour to create a gluten-free version, or substitute coconut oil for butter for a dairy-free option. For a sweeter bar, increase the sugar slightly, or add a bit of vanilla extract for additional depth.
Storage and Reheating Tips
Store your lemon bars in an airtight container in the refrigerator for up to a week. You can also freeze them for longer storage. Simply cut into squares, wrap them tightly in plastic wrap, and store in a freezer-safe container. To reheat, let them thaw in the refrigerator overnight and enjoy cold or at room temperature.
FAQ
1. Can I make lemon bars ahead of time?
Absolutely! Lemon bars can be made a day in advance. Just ensure they are properly covered and stored in the fridge.
2. How do I know when the lemon bars are done?
The filling should be set and lightly golden around the edges. A slight jiggle in the middle is normal; they will firm up as they cool.
3. Can I use bottled lemon juice?
While you can use bottled lemon juice, fresh lemon juice provides a significantly better flavor and aroma!
4. How should I cut my lemon bars?
For neat cuts, use a sharp knife and wipe it with a damp cloth between each cut. This prevents the filling from sticking to the knife.
5. Are lemon bars gluten-free?
This recipe is not gluten-free, but you can substitute regular flour with a gluten-free blend to make them suitable for a gluten-free diet.
