Rhubarb crisp is one of my all-time favorite “old timey” desserts. I call it old timey because aClassic Rhubarb Crisp recipealways reminds me of childhood and my parents and grandparents.

Rhubarb itself just seems like one of those classic old-fashioned garden items that doesn’t get the attention of other more in-fashion produce.

Ialways think the best rhubarb is the stalks that come for a friend, neighbor or relative’s backyard or garden.

The rhubarb found in the store just isn’t quite as awesome. The stalks are usually much smaller and it doesn’t hold up to those big, sturdy homegrown stems. But, since I don’t have a rhubarb plant of my own, I have resorted to buying it in the grocery store.

Last weekend I was lucky enough to stop at a garage sale where they were selling big bags of rhubarb for only $1!! I snatched that up in a hurry and now wish I had bought more to stock the freezer.

I used up the rhubarb I did buy for my favorite of all rhubarb recipes – to make up a pan of this Classic Rhubarb Crisp Recipe. As usual, it was DELICIOUS!!

Moving forward, I definitely need to plant some rhubarb in my own yard. I have done some exploring online and found out that I can order rhubarb bulbs from Burpee. I remember my parents getting their catalog in the mail every year before the days of the internet!

Ordering online will be much quicker, but I think I want to see if I could start getting that catalog again. If you need rhubarb plants too, you can buy them right here.

If you end up with too much rhubarb (is that even a thing??) you can use the extra to make rhubarb vinegar. It’s so delicious and versatile.

My favorite part of this tasty rhubarb dessert is the crisp topping! The brown sugar helps to give it that delicious flavor and adds to the crisping too.

To serve this old-fashioned Rhubarb crisp, my favorite way is just as-is with nothing on top, but you can top it with vanilla ice cream, whipped cream or anything else you like.

Just make sure not to put topping on until right before eating so that the crisp topping stays crisp!

Now on to the super delicious rhubarb recipe!! If you love it as much as I do, please use the buttons above to share it by pinning on Pinterest or sharing with your friends on Facebook!

NOTE: The recipe as written is very sweet. I mentioned Grandma, and mine made everything super sweet. She even added an extra cup of sugar when mixing up Country Time Lemonade! So, usually when I make this recipe now I use only 3/4 cup of white sugar rather than a full cup in the rhubarb layer.

FAQs

Why is my rhubarb crisp runny? ›

Why is my rhubarb crumble dry? ›

Usually it's the crumble that wrong. It might be too lean, making it rather dry and everlasting to eat, or it's undercooked so that it has the pasty flavour of uncooked flour.

Where did rhubarb crisp originate? ›

Rhubarb Crumble is a classic British dessert, made with a vegetable-slash-fruit originally from Siberia. It's associated with springtime, but I only just this week managed to get my hands on some. It's both hothouse-grown and field-grown in the US and has been cultivated in the UK since the 1600s.

Not adding a thickener

Fruit is naturally watery, and when it bakes, that liquid cooks out and mixes with your sugar and spices to create a delicious sauce. However, you don't want your apple crisp weeping everywhere. Just toss in a little cornstarch or tapioca starch with your fruit before baking.

What happens if you put too much butter in crumble? ›

If you use more butter than the recipe calls for, the crumb topping will be melted and greasy. If you don't use enough butter it will be dry and floury.

Why is my crumble not crisping up? ›

How do you firm up rhubarb? ›

Spread a single layer of cut rhubarb on trays, freeze until firm (1 to 2 hours), then put in air tight bags or containers. Rhubarb may also be frozen with sugar or syrup. For a sugar pack, mix 1 part sugar and 4 parts rhubarb and allow to stand until sugar is dissolved before packing into freezer containers.

What is the difference between fruit crisp and crumble? ›

What to do with a bunch of rhubarb? ›

How to keep rhubarb pie from being runny? ›

Thankfully the science of baking has an easy trick up its sleeve to deal with this, and all it involves is tossing your rhubarb with some sugar. Mixing your fresh fruit with sugar and letting it sit is called maceration, and it helps draw excess liquid out of your rhubarb before it cooks out and leaves your pie soggy.

Why is my crumble watery? ›

The ingredient list for a crumble or crisp is relatively short, but don't be tempted to leave out the cornstarch. As fruit cooks, it releases its juices, becoming saucy and soupy.

How do I make my rhubarb thicker? ›

The rhubarb plant is a "heavy feeder." The plant must take in large amounts of nutrients from the soil to produce its large stalks and leaves. Make it an annual practice to supplement the soil with either a balanced commercial fertilizer or rich compost, or both.
