We love Rhubarb!

When I go look at my rhubarb patch and I see it’s so full and almost taking over the north side of my garden it would be easy to feel overwhelmed. Instead, I often wonder if it’s enough to get us through the winter.

About once a week I go out a cut as much as I can carry. I trim the leaves, poisonous, and leave them outside. Then I wash it, chop it and measure it out into quart freezer bags. My goal is to have enough bags of rhubarb in the freezer to use one bag a week all winter long. Once I have that goal in mind, I never feel like the rhubarb is too abundant.

  • 2 cups of flour
  • 2 cups of quick cook oats
  • 1 1/3 cups of brown sugar
  • 1/2 tsp baking soda
  • pinch salt
  • 1 cup butter
  • 2 1/2 cups rhubarb
  • 1/4 cup water, if you're rhubarb was frozen you probably won't need this
  • 1 cup Sugar, more or less if you prefer sweeter or tangy
  • 4 TBSP flour
  • 2 cups sliced strawberries


  1. Preheat the oven to 350˚ Make the Crust/Topping:
  2. mix the dry ingredients together
  3. cut the butter in chunks and drop it in the dry mix, cut in with a pastry blender or two knives, or use your hands mix it in
  4. keep mixing until it's looks like coarse crumbs
  5. save off 1 cup of crumbs
  6. press the rest in the bottom of a 9X13 baking dish
  7. Make the Filling
  8. put the rhubarb, water (if using) and sugar in a sauce pan
  9. bring it to a boil over medium high heat, it will get very juicy as it cooks
  10. once it comes to a boil reduce the heat to keep it from scorching, just keep it bubbling lightly until the rhubarb is just starting to get soft
  11. add the sliced strawberries and cook for one more minute or so
  12. remove 2/3 cup of the juice and whisk in the flour into it
  13. add it back in the pan and stir until thickened, cook and stir for 1-2 minutes and remove from the heat (you just made rhubarb gravy!)
  14. spread the strawberry rhubarb mixture over the base layer in the 9X13 sprinkle with reserved crumbs
  15. bake for 30-35 minutes until top is lightly brown and the strawberry rhubarb layer is bubbly
  16. let it cool before you cut it for best results
