Hello, welcome to Djalali Cooks. I love a classic lemon bar. The sweet/tart flavor of lemon custard sitting on top of a lightly sweet shortbread crust; it’s a fantastic dessert. It’s perfect anytime of year, but its brightness feels especially right come spring. We are giving the classic lemon bar a little twist by adding fresh basil to the shortbread. Infusing this sweet/tart treat with a fresh and verdant herbal flavor. Basil’s natural sweetness melds with the lemon in such a gentle and natural way. A great twist on a classic, it’s Basil Lemon Bars!
This recipe is really simple, and aside from the time spent cooling between baking the shortbread and baking the lemon curd, it’s all pretty quick.
Start by preheating the oven to 350 degrees F. Line a 13 x 9-inch baking pan with parchment; leave about 2-inches of parchment climbing up the sides of the pan. Spray the parchment with cooking spray. To make the parchment cooperate in the pan, you may need to spray the bottom of the pan, then press the parchment into the pan.
Basil Lemon Shortbread Crust
In a food processor, combine basil, kosher salt, lemon zest, 2 cups of flour and 1/2 cup of granulated sugar.
Process the mixture until the basil leaves are chopped up very small – about 1 minute.
Then add the cubed butter and pulse until the mixture is crumbly and sandy, about 15 pulses.
Transfer the shortbread mixture to the prepared baking pan and firmly press the dough into the pan.
Bake the shortbread in the preheated oven for about 30-35 minutes, until it’s lightly golden. When you pull it out, be sure to leave the oven on.
Let the shortbread cool for about 20-30 minutes.
Lemon Custard
In a large bowl, whisk together the eggs, lemon juice, baking powder, remaining 1/4 cup flour and 2 cups of sugar.
Pour the lemon custard mixture on top of the cooled basil lemon shortbread. Gently tap the pan on the counter a few times to release any air bubbles.
Bake in the 350 degree oven for 30-35 minutes, until the lemon curd is set. Let the Basil Lemon Bars cool on a wire rack for about 1 hour.
Then, cut into 2-inch squares and sift with powdered sugar. I like to use my pizza blade cutter for jobs like this.
And that’s it! You can keep the Basil Lemon Bars covered in the fridge for 3-4 days. Like I mentioned at the top, the basil adds just a little herbal sweetness to these bars that really sets them apart from your average lemon bar. Such a refreshing and bright flavor combination. I do hope you give these a try! I have a number of citrusy desserts on Djalali Cooks; try Atlantic Beach Pie, or Lemon Cake with Lemon Cream Cheese Frosting. Take care and be well, xo Kelly

March 30, 2023 at 10:14 amLemon bars are a longtime favorite at our house. I don’t recall my mother ever making or buying them, but my mother-in-law made some good ones, and they disappeared quickly, and I have made them more than a few times! I like the addition of basil. It will be deliciously different, and our taste buds need help waking up after a long cold winter of comfort foods. It’s time to be reenergized, and I am looking forward to the change. I will let you know how long these last. My guess is it won’t be long. 😊 Happy Thursday Kelly, and have a wonderful day.
