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.

Should I thaw rhubarb before baking? ›

It is not necessary to thaw frozen rhubarb before cooking with it, but if you are baking with rhubarb, it's best to thaw it first as it shrinks a bit after thawing and you want an accurate measurement. Frozen rhubarb will keep for 1 year. It is still safe to eat after that, but its quality will decline.

Go for whatever is in season to help keep costs down, too. Apples, clementines, bananas and rhubarb are good sources of vitamin C, which is good for boosting your immune system and wound healing. Dried raisins are a source of iron, which is needed to make the oxygen carrying part of your blood.

Does rhubarb need a lot of sugar? ›

Rhubarb can be eaten in a number of ways. It is usually used in jams and desserts, which contain plenty of added sugar. That said, it's easy to use in low-sugar recipes — or even cooked with no sugar at all.

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.

How do you keep crumble topping crunchy? ›

They're supposed to be chunky and craggy, with big pieces of crumble on top. By freezing your topping, it makes it harden just slightly and that means the texture will be nice and crispy when it's cooked.” To do this properly, you first need to make sure that the topping is still a little lumpy.

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 many cups is 2 pounds of rhubarb? ›

A cup is a measure of volume while pounds is a measure of weight so a direct calculation is difficult. If we only take liquid weight into account, one cup is eight ounces and two pounds would be 32 ounces so two pounds of rhubarb would equate to 4 cups.

How many stalks of rhubarb make a cup? ›

Recipes generally call for pounds, cups or number of stalks. One pound of rhubarb makes about 4 cups, or 1 quart, of cut-up rhubarb. Four stalks of rhubarb equals approximately 2 cups of diced rhubarb.

Do I need to peel rhubarb before baking? ›

Cut away and discard any tough, woody, or bruised parts of the stalks. Wash the stalks thoroughly and scrub with a vegetable brush. 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.

Do you add sugar when freezing rhubarb? ›

You can also toss sliced rhubarb with granulated sugar, which helps prevent freezer burn by minimizing the rhubarb's exposure to air.

Is rhubarb a fruit or a vegetable? ›

Rhubarb is a vegetable often thought to be a fruit. There's actually a good reason for this confusion: in 1947 the USDA classified it as a fruit because the tariffs on bringing fruits into the country were lower on fruits than vegetables. In actuality though, rhubarb is a vegetable - a member of the buckwheat family.

Can you substitute white sugar for brown sugar in crumble topping? ›

If you don't have brown sugar, you can use all granulated white sugar instead. If you do, add 1/2 teaspoon vanilla extract and maybe a pinch of cinnamon or another spice you have just to add a little flavor (as some will be lost if you don't use brown sugar).

What does rhubarb taste like without sugar? ›

Rhubarb has a naturally tart flavour, so the addition of sugar made a delicious sweet and sour combination which lent itself perfectly to a sweet rhubarb pie.

What makes rhubarb sweet? ›

Rhubarb is usually known for its extremely sour flavor that's best tempered with a generous amount of sugar and other fruits to produce sweet stalks (check out these recipes for some inspo).
