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 soggy? ›

TROUBLESHOOTING: WHY IS MY RHUBARB CRISP RUNNY? It's pretty typical for any kind of fruit crisp to be a bit liquid-y while it's still warm. The juices are flowing and they are just thinner because of the warmth. But as long as you used the right amount of cornstarch, it should “gel” quite a lot as it cools down.

Should you soak rhubarb before baking? ›

Wash rhubarb with cool tap water, but do not soak.

Does rhubarb need to be cooked before baking? ›

Absolutely not. I have never pre-cooked the rhubarb. In fact, I think it would be a runny mess if you did.

What is the difference between rhubarb crisp and crumble? ›

So what's a crumble vs. a crisp? A crumble is just a crisp without oats in the streusel. It may feature nuts, but the streusel topping is usually a simple combination of butter, flour, and sugar that is more clumpy than that of a crisp.

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.

How to take the tartness out of rhubarb? ›

Solution: Soak the rhubarb in water to reduce the acid, simmer in orange juice and sugar (and don't stir too much) to retain texture and color, and layer with lightly whipped, sweetened cream for ideal flavor and texture and an attractive, unusual presentation.

What happens if you don't peel rhubarb? ›

So, in conclusion: You don't have to peel rhubarb before eating it. Of course, you can if you want to. But doing it means that some of the lovely red flavor is going to disappear. I usually just prepare rhubarb by rinsing it and then cutting it into thin slices!

How to cook rhubarb without it going mushy? ›

Method. Put the rhubarb into a saucepan with the orange zest, juice, sugar and 2 tbsp water. Bring to the boil then simmer for 8 mins until the rhubarb is cooked but still holds its shape.

Why do you pull rhubarb instead of cutting? ›

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.

How much baking soda do I put in rhubarb? ›

Neutralizing Rhubarb's Acidity

Once the rhubarb has given up its juices, pull it from the oven and stir in a quarter teaspoon of baking soda using a heat-resistant spatula.

Can you eat rhubarb raw? ›

Its stalks are deeper red and tinged with green, while its leaves are bright green. It has a more intense flavour and robust texture than the forced variety. Although it can be eaten raw, rhubarb tends to be too tart this way, and it's usually best when cooked with plenty of sugar.

When not to use rhubarb? ›

Kidney disease: There are chemicals in rhubarb that might harm the kidneys or increase the risk of kidney stones. If you already have kidney disease, avoid rhubarb. Kidney stones: Rhubarb contains a chemical that the body can convert into kidney stones. If you have ever had kidney stones, don't take rhubarb.

Should you peel rhubarb before baking? ›

Preparation of fresh rhubarb

If you buy it during the peak season (April to June), peeling isn't necessary. But after peak season, the stalks can be tough, and peeling with a small and sharp knife might be necessary to help make it more palatable (via BBC Good Food).

Why is my rhubarb pie so runny? ›

The rhubarb contains so much water, you either have to add too much thickener or coax the rhubarb to release its liquid before thickening it. What's the answer? To solve this problem, I mix the rhubarb with the sugar. Over time, the sugar draws out the excess juices.

How do you fix a soggy crumble? ›

If you think it's too wet, add a little more flour to soak up the extra butter.

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 going soft? ›

Rhubarb plants can be prone to honey fungus, crown rot and viruses. Any of these diseases will weaken the plant and it is best to dig up affected plants and start again on a new site. Crown rot is the most common. It's a fungal infection at the base of the stalks, and causes the crowns to turn brown and soft.
