Ingredients
FOR THE CRISP TOPPING
½ cup plus 2 tablespoons/141 grams unsalted butter
1 ¼ cups/160 grams all-purpose flour
½ cup/100 grams light brown sugar
½ cup/55 grams sliced almonds
½ teaspoon kosher salt (such as Diamond Crystal) or ¼ teaspoon fine salt
FOR THE RHUBARB
2 pounds rhubarb, chopped into 1-inch pieces (8 cups)
½ cup plus 2 tablespoons/113 grams granulated sugar
2 tablespoons all-purpose flour
2 teaspoons vanilla paste or extract
½ teaspoon finely grated orange zest
Pinch of kosher salt
Vanilla ice cream or lightly sweetened whipped cream, to serve
Preparation
- Step 1
Heat oven to 350 degrees. Meanwhile, brown the butter: Melt ½ cup/113 grams of the butter in a small skillet set over medium heat. (Use a skillet with a light interior so you can easily see the milk solids change color.) Cook the butter, stirring occasionally and scraping the milk solids off the bottom and sides of the pan as needed, until the milk solids turn golden brown and smell toasty, a few minutes. Transfer the butter to a medium heatproof bowl. Cut the remaining butter into 2 pieces and add it to the bowl with the hot butter. Stir occasionally until all the butter melts.
- Step 2
Add the flour, brown sugar, almonds and salt to the butter, and stir together until evenly combined and clumps form. You may need to use your fingers to do the last bit of mixing.
- Step 3
Prepare the rhubarb: In a 9-by-9-inch (or 9-inch round) baking dish, combine the rhubarb, granulated sugar, flour, vanilla paste, orange zest and a pinch of salt. Stir until combined and evenly mixed. Press the rhubarb gently into the pan, then scatter the crumble evenly over the top.
- Step 4
Bake until the topping is deep golden brown and the rhubarb juices are bubbling, 55 to 65 minutes. Cool slightly, then serve warm with ice cream or lightly sweetened whipped cream. Store any leftovers in an airtight container in the fridge for up to 2 days. The topping will soften as it sits.

Delicious! Very rhubarb-y!!! Made with ingredients as stated. Only had 8x8 glass dish, worked fine. Note that I do look at recipe commenter suggestions to reduce sugar to avoid being "too sweet" but would not do that here. This struck a good balance. There was some sweetness but it still very much allowed the rhubarb tartness to come through and let rhubarb be a dominant flavoring.
The brown butter is such a tasty addition to the crumble and definitely adaptable for many fruits. I was always intimidated by brown butter, but it isn't as hard as I feared. I only had 1 lb of rhubarb from my CSA, So I added frozen blueberries. Also had an excessive amount of ginger from said CSA, So I added about 1.5 to 2 tablespoons of finely chopped ginger. Ginger and rhubarb is a delicious combination!
I made this with only a pound of rhubarb in a 9-inch round and pecans instead of almonds with great results. One of my go-to rhubarb recipes!
Definitely don't skimp on the sugar in the topping. I found the dish to be barely sweet enough as is. Also the topping is not a crisp, as others have noted--it is more of a paste, like cookie dough, even after baking for over an hour. It's pretty tasty but just not a crisp in the traditional sense--kind of a mush.
I did 1.5 x the recipe and used a 9x11 inch pan. Perfect ratio. I eliminated the orange zest b/c I didn't have any oranges. Added some cinnamon and dash of cardamom to the rhubarb mixture. Brought to a family event and it was a huge hit.
I followed the recipe exactly but went 50/50 with rhubarb and strawberries. I don’t bake much and this was one of the best things I’ve ever made.
