This tangy rhubarb crisp recipe is the perfect way to enjoy fresh rhubarb stalks. Rhubarb is in season from April through June, so get some when you can!
Rhubarb is actually a vegetable, but it tastes like a fruit when added to a crumble or a pie. While it's a little too tart raw, it's delightful when baked with some sugar.
Why You'll Love This Rhubarb Dessert
If you like crisps and crumbles, you'll love this tangy and tart dessert. Its crispy, nutty topping is offset by a citrusy and flavorful rhubarb center.
It pairs perfectly with a scoop of vanilla ice cream or some whipped cream.
Ingredients You'll Need
Because rhubarb has such a tart flavor, we've increased the amount of toppings we typically use per cup of fruit. This is an almost 1 to 1 ratio of fruit filling to crisp topping. Here's what you'll need.
Rhubarb - You'll need 1 pound of fresh rhubarb stalks for this recipe. Remove any leaves from the stalks as they are toxic to humans.
Mix-ins - To mix with the rhubarb, you'll need 1 cup of brown sugar, 2 tablespoons of orange juice, 2 teaspoons of orange zest, and 1 teaspoon of lemon zest. You'll also add in a teaspoon of cardamom (or cinnamon if you don't have cardamom). Finally, you'll want ½ tablespoon of cornstarch to thicken up the fruit filling.
Crisp Topping - You'll need 1 cup of rolled oats, 6 tablespoons of butter, ½ cup of flour, a ½ cup of pecans, ¼ cup of pistachios, and 2 tablespoons of honey (or granulated sugar).
Choosing the Best Rhubarb
Rhubarb stalks should be firm and not floppy. They'll also have a nice shine to them when they've been recently harvested.
Some varieties are harvested when they are green and pink, and some are better when they're all bright pink - the color doesn't affect the flavor too much (although the bright pink is very pretty)!

Tips for Making this Recipe
Cooking Tips - You want a crispy crust, so keep an eye on this for the last 5 minutes of bake time. Don't let it burn, but if it's not getting golden brown, let it bake an additional 5 minutes.
Storing Tips - Store leftover crisp in the refrigerator for up to 5 days. It freezes well - you can save it in a freezer-safe container for up to 3 months.
Diet/Allergy Alternatives - If you'd like to make this recipe vegan, sub the butter for vegan butter and the honey for granulated sugar.
