No Fuss Deliciously Simple Pie

No pie crust to make and roll out. Just dice the rhubarb and butter your pie plate. Blend the rest of the ingredients and bake! That’s it!

I had the easy part of this recipe – the blender. My daughter had to dice all of the rhubarb. Note, when preparing the rhubarb…do not use the leaves of the rhubarb – I have always been told that they are poisonous.

Baking does not get any simpler than this.

The custard has a creaminess that is slightly sweet because of the little bit of added sugar. Pair this with the tangy rhubarb and you have a great combination for your taste buds. I don’t even miss the pie crust when eating this.

However, my daughter and I do think that this tastes best when served with whipped cream or ice cream.

Fresh Versus Frozen Rhubarb

Often, we have more rhubarb in the spring of the year than we can eat. Therefore, we clean, dice, and freeze the extra rhubarb in plastic containers or freezer bags. Normally, about 2 or 3 Cups in each container.

That way, we can just add the frozen rhubarb to whatever recipe we are making. This recipe and many other rhubarb recipes are very forgiving. I have used both fresh and frozen rhubarb with no problem. No need to thaw before use either.

This is a great way to use frozen rhubarb. Bake in the oven an extra 10 minutes because the center needs a little more time. it will puff up beautifully. Eat with a little ice cream.

As you can see from the first photo, this pie was made in a decorative pie plate. You can find the one I used here in my store.

Rhubarb Pie or Bars?

Well, we tried this recipe as both a pie and bars. The bars had to cook only 30 minutes. We made this in a cake pan for bars.

However, both my daughter and I thought that this recipe tasted better as a pie. The custard is thicker, which adds just the right amount of creaminess. Therefore, we recommend this recipe as a pie.

What is Rhubarb?

According to Healthline, rhubarb is a vegetable that requires a cold winter to grow. In Wisconsin, we have the cold winters and each spring, this perennial plant sprouts out of the ground with the sour stalks.

When I was a child, I used to bring a small bowl of sugar out to the garden. Then I would pick a stalk of the rhubarb and dip it in the sugar and eat it. I remember only being able to eat 1 or 2 stalks at one time. Too sour after a while – even for a child’s taste buds.

When to Harvest Rhubarb

Do maybe have a rhubarb plant or two growing somewhere on your property? You might be wondering about harvesting. Generally, in Wisconsin, we are able to start enjoying this in May-June.

According to Cumberledge, K (2020). How to Harvest Rhubarb, once the stalks are at least 10-12 inches long. it is time to start picking. This will make sure that the plant will stay healthy for the next year. In her article, she also detailed information about harvesting, trimming, and storing of rhubarb, There is a lot of useful information.

This was incredibly easy to make and I love that it wasn’t even *that* much sugar compared to other recipes. It was super tasty! I altered it a little bit. I did about 2 1/4 cups of rhubarb and about 1 cup of strawberries. It turned out amazing!

Very easy to make and so good! I was craving a rhubarb recipe with custard but didn't want to mess with making a crust. I had some heavy cream to use up, so used half cream and half milk. The additional richness was Not a problem lol!

Is this to be served warm or chilled? You didn’t mention that but in my head, anything custard would be cold.

Thanks!

Let it cool to room temperature to serve. It is also wonderful chilled. Vicky

I made this today following the recipe, however after I let it rest it had a puddle of liquid in the centre. Any suggestions? It was very brown on top. The outer edges were tasty.

It sounds like it wasn't cooked through in the center. Did you let your oven preheat before baking? I would check the oven temperature with a thermometer for accuracy, as you may have to adjust the temperature. Lastly, if the edges were over cooking and the center undercooking, you can put aluminum foil around the edges of the pie to keep them from overcooking before the center finishes baking. Hope one if these tips works for you. Vicky
