Notes

  • This can be a fresh rhubarb pie or a frozen rhubarb pie. We make it both ways.
  • The filling may be pink or green just depending on the variety of rhubarb you use. 
  • You'll need two pie crusts. Either buy some pre-made from the refrigerated section, or make your own. If you use a refrigerated crust, follow the directions on the package. Most say to remove from the refrigerator prior to using.
  • This recipe calls for two cups of rhubarb. Be sure this is only the stalks. Wash the stalks to remove the dirt. Cut into small chunks, approximately 3/4 inch.  If there's woody ends, you can peel them off.
  • The recipe follows a two-step cooking process. The first 15 minutes is at 425 degrees F, then turn down the oven and cook at 350 degrees F for an additional 45 minutes.
  • The filling may seep out the top. This is ok! It tastes great anyways. You may want to place the pie pan on a flat cookie sheet in case the filling bubbles over.
  • It is best if you allow the pie to rest for an hour before cutting. This lets the filling cool and set up. If you don't do this, the filling will ooze out when you cut it.
