How to Make a St. Patrick's Day Celtic Knot out of Pie Dough

Here is an easy way to add a festive touch to your favorite pie. Custard pies, like cinnamon or sweet potato, are great options for this project. Be sure to prepare one in advance. You will also need parchment paper and a printed image of the Celtic knot you would like to create.

Cutting dough for the knot

Follow a good recipe for basic pie dough. Once it is ready, roll it out on a lightly floured surface. Then cut out curved strips of pie dough to about a 1/2 inch wide and 10 to 12 inches long. A soup bowl is a great guide for cutting strips for a larger knot, and biscuit cutters work nicely as a guide for a smaller knot.

Use a printed out celtic knot image as a guide

Place a printed image of a Celtic knot on your workspace, then lay a piece of parchment paper over the top. This "cheat-sheet" will be a tremendous help in creating a clean and symmetrical knot. 

assemble the knot

Using the image as a guide, place strips of dough in a Celtic knot pattern on the parchment paper. For this paticular knot, starting with the circular section works best.


Continue to assemble the knot

Continue adding strips of dough, weaving in and out through each section. Be patient: This project will challenge your lattice skills!

finished celtic knot

Once the Celtic knot is complete, pull out the printed image from underneath the parchment paper. Pinch together the edges at each point and gently press the dough at each intersection. Transfer to the refrigerator and let chill for at least 30 minutes.


Preheat oven to 350 degrees. Brush finished knot with egg wash and sprinkle with sugar. Transfer to oven and bake until the dough is golden, about 10 to 15 minutes.

Remove baked dough from the oven

Remove from oven. Let baked knot cool completely.

Transfer to prepared pie

Place baked Celtic knot on top of your prepared custard pie. Two of my favorites are Martha Stewart's cinnamon custard pie and her sweet potato pie.

Serve and enjoy

Add additional decoration as desired. Serve and enjoy!
