Grease Pie Plate: Make sure to grease the pie dish well to prevent sticking. This recipe uses butter for this.

Cooling Time: Allow the pie to cool at room temperature before slicing. This allows the custard to set and makes for cleaner slices.

Experiment: Feel free to get creative! You can add a handful of berries for added taste and color. Create a strawberry rhubarb pie by adding a handful of fresh strawberries. Create a raspberry rhubarb pie for added sweetness.

Serving the Rhubarb Pie

However, my daughter and I do think that this tastes best when served with whipping cream or a scoop of vanilla ice cream. A creamy custard element that complements the tartness of the rhubarb.

It is really best served the same day. While it can be stored in the refrigerator and enjoyed the next day, it will take on a more custard taste.

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.

However, fresh is best. Use fresh rhubarb for the best flavor and texture. Look for crisp, firm rhubarb stalks, and avoid wilted or limp ones.

This is something we look forward to every rhubarb season in the late spring. However, if you don’t have a rhubarb patch to pick your own, look for fresh stalks during the season in your local grocery 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.

FAQs

Should rhubarb be peeled for pie? ›

You don't need to peel peak-season rhubarb, but by midsummer, the stalks tend to be tough and fibrous. You might need to peel them to make them tastier.

How do you keep rhubarb pie from getting soggy? ›

Brush Your Pie in Egg Wash

Once you've pre-baked your pie, brush the bottom and sides of the crust with egg wash, then reheat at 400° for 4 minutes to set the glaze. This creates a seal between the crust and the filling so that your crust stays crispy and golden once the filling is added.

Why is my rhubarb pie so runny? ›

Macerate Your Rhubarb With Sugar To Draw Out Excess Liquid

The reason rhubarb pie gets so runny is that rhubarb is 95% liquid, which puts it near the top of watery fruits and vegetables alongside things like melon and cabbage.

Is it better to cut or twist rhubarb? ›

Depending on the variety, they may be only 12 inches long, or as long as two feet. To pick rhubarb, hold the stalk firmly, pull and twist. Do not use a knife to cut the stalks from the plant. The knife can carry diseases from plant to plant, and the remaining stalk can be a point of entry for other pests.

What part of rhubarb can you not eat? ›

Rhubarb leaves are toxic and humans should never ingest them. The stems are safe to eat.

What to put on the bottom of pie crust to keep it from getting soggy? ›

Brush the Bottom with Corn Syrup or Egg White

Coating the inside surface of the bottom crust will create a barrier to prevent sogginess.

Is frozen rhubarb as good as fresh? ›

You can use frozen rhubarb the same way as fresh: in sauces, pies, crumbles, and beyond. Although thawing the rhubarb isn't necessary for cooking, you can do so by leaving it out for a few hours if you wish.

How do you get a crispy crust on the bottom of a pie? ›

Getting a brown, flaky/crispy bottom crust on your pie is all about quick and effective heat transfer. That's why aluminum or aluminum/steel pans — rather than glass or stoneware — are your best choice for baking pie. Metal, especially aluminum, transfers heat quickly and efficiently from oven to pie crust.

How big should you cut rhubarb for pie? ›

Slice the rhubarb and trim off any tough ends or residual green leaves (the leaves are toxic). Slice it into approximately 1 inch / 2.5 cm pieces. I like to slice on the bias (diagonal cuts) because I think it looks prettier, but any cut is fine, of course.

When should you not pick rhubarb? ›

The best time to harvest rhubarb is during the months of May, June and early July. After this, it's best to let the plant be, so it can regrow and recharge to survive the winter. You can cut the flower stalk away before it blooms to help extend the harvesting season.

Is rhubarb good for you? ›

Rhubarb is rich in antioxidants, particularly anthocyanins (which give it its red color) and proanthocyanidins. These antioxidants have anti-bacterial, anti-inflammatory, and anti-cancer properties, which help protect you from many health-related issues such as heart disease, cancer, and diabetes.

Should rhubarb pie be kept in the refrigerator? ›

As surprising as it might sound, rhubarb pies can last for up to three days when kept at room temperature. Shoving your pie into the fridge can have an adverse effect, turning your delicate pie into a soggy mess that isn't quite as appealing to scoop out of the pie dish and serve.

How do you get the most Flavour out of rhubarb? ›

Removing the first layer of skin will take away its "rubbery taste" and bring out the stalk's most appealing flavors, and the brown sugar will temper the tartness.

What can I use to thicken rhubarb? ›

Corn Starch – I use corn starch because it's widely available and many people keep it in the pantry. Rhubarb exudes a lot of juice and needs the starch to thicken the filling. The recipe has just enough starch to keep the filling from becoming soupy, but not so much it becomes pasty.

Why do you put a bucket over rhubarb? ›

Forcing rhubarb

Earlier harvests of sweeter, tender, pale stalks can be produced by covering rhubarb plants with a forcing jar, tall bucket or dustbin in mid-winter, so the stems form in the dark. Choose an early variety, such as 'Timperley Early', and only use a strong, healthy plant.

Why do you pull rhubarb and not cut it? ›

Cutting a rhubarb leaves part of the stalk behind. This leftover stalk can then rot and infect the root of the rhubarb plant. When you pull and twist rhubarb off, it comes off straight from the root. Now the plant will know a whole stalk is gone and set to work replacing it.
