Old-fashioned Easy Rhubarb Crisp Recipe

I love this time of year and always look forward to when my rhubarb plants are big enough to harvest.  The problem is that I have so much of it and I never want to waste it so I end up doing a lot of cooking with it. I also make some lovely rhubarb wine with it and also freeze much of it for use in the colder months. 

One of the recipes that I make every year and that my family loves is this easy rhubarb crisp recipe. It’s a great way to use up quite a bit of rhubarb at a time. 

This recipe is quite simple to make and can easily be doubled or tripled depending on how many people you’ll be feeding.  I’ve often made large batches of this to bring with me to summer picnics and barbeques and it’s always been a big hit.

The last time I made this easy rhubarb crisp recipe was when I was having a couple of our friends over for an outdoor dinner, which is something we do a lot of in the warm weather months. I opted to make this in an 8-inch cast iron skillet, and it came out beautifully.

I love cooking in cast iron whenever possible and is something I highly recommend investing in. I’ve had some of my cast iron for over 20 years, and they only get better with age.

Making this Easy Rhubarb Crisp Recipe

The steps to making this easy rhubarb crisp recipe are pretty simple and straightforward.

easy rhubarb crisp recipeThe first thing you want to do is chop up 5 cups of rhubarb.  I cut mine into 1/4 to 1/2 inch pieces. 

Once you have cut up the rhubarb, put the pieces into a mixing bowl and add one cup of sugar and 3 tablespoons of flour and stir well. Pour this into your cast iron skillet or baking dish.

To do this, cut the cold butter into 1/2-inch pieces and add to the flour and oat mixture.  When using a fork to cut in butter, simply smash the butter pieces until you have achieved the desired crumbly consistency. 

Add your nuts or coconut at this point and gently incorporate into your crumble mixture.

Let cool a bit and serve warm with ice cream, whipped cream, or light cream drizzled over.  This is also perfectly fine served cold as well and is still delicious.
