Instructions How To Make Rhubarb Berry Crisp  

  1. Preheat oven to 375°F. Grease an 8-inch or 7-inch x 11-inch baking dish that can hold about 2 quarts. Set aside.
  2. Make the homemade filling: Combine strawberries, rhubarb and cherries with the flour and sugar in a large bowl. Toss gently until combine, then spoon and spread into prepared baking dish.
  3. Shortcut Filling Version: Use a can of strawberry pie filling and a can of cherry pie filling and just add in small, chopped rhubarb. No extra sugar or flour needed. Just mix it all together and you have instant filling, ready to bake because the rhubarb is raw to start with. Make sure you cut the rhubarb in small ½ inch chunks, so it cooks through thoroughly.
  4. In a small bowl, combine the flour, oats, brown sugar, baking powder and salt. Cut in butter using a fork or pastry cutter until mixture resembles coarse crumbs. Sprinkle the streusel mixture over rhubarb berry mixture. Add some additional oats on top for visuals if desired.
  5. Bake until the crisp topping is lightly brown and filling is bubbly, about 35-40 minutes. Serve a la mode and warm with a scoop of ice cream for next level yumminess!

Pro Tips

  • Keep that butter cold. Cold butter = the crispiest, crunchiest oat topping.
  • Slice rhubarb like celery. No peeling, no fuss — just chop and drop.
  • Let it rest. Give your crisp 10–15 minutes after baking so the juices settle into that perfect jammy goodness.
  • Frozen fruit? Totally fine. Just thaw + drain so your crisp doesn’t turn into a berry soup.
  • Go big on oats. Extra oats = extra farmhouse crumble magic.

Variations 

  • Strawberry‑Only Crisp: Skip the cherries and go full strawberry fields.
  • Mixed Berry Crisp: Toss in blueberries, raspberries, blackberries — whatever’s in your basket.
  • Peach Rhubarb Crisp: Summer in a pan.
  • Nutty Crunch: Add chopped pecans or almonds to the topping for extra texture.
  • Cinnamon‑Vanilla Cozy: Add a splash of vanilla + a sprinkle of cinnamon for warm bakery vibes.
  • Gluten‑Free: Swap in your favorite 1:1 GF flour — crisp still turns out perfect.

Storage & Reheating 

How to Store It

  • Fridge: Store leftovers covered for 3–4 days.
  • Freezer: Freeze in an airtight container for up to 2–3 months.
  • Make‑Ahead: Assemble the fruit filling and topping separately, then sprinkle + bake when ready.

How to Reheat It

  • Oven (best): 350°F for 10–15 minutes until warm and crisp again.
  • Microwave: 20–30 seconds for a quick fix (topping will be softer).
  • From Frozen: Thaw overnight, then warm in the oven to revive that buttery oat crunch.

Serving Ideas 

  • Scoop of vanilla ice cream — the classic “melts‑right‑into‑the‑crisp” magic.
  • Fresh whipped cream — light, fluffy, and perfect with tart rhubarb.
  • A drizzle of warm caramel — farmhouse‑fancy and ridiculously good.
  • Lemon zest on top — brightens the berries and adds a sunny pop.
  • Toasted almonds or pecans — extra crunch for that bakery‑style finish.
  • Serve it warm on the porch — bonus points if you’ve got a summer breeze and a mason jar of sweet tea.

FAQs

Do I need to peel rhubarb?

Nope! Just wash, slice, and you’re good to go.

Are the leaves really poisonous?

Yes — toss those leaves immediately. The stalks are totally safe.

Can I use frozen rhubarb or frozen berries?

Absolutely. Thaw and drain first so your crisp stays crisp.

Why is my crisp runny?

Too much liquid from frozen fruit or not enough resting time. Let it cool a bit and it’ll thicken up.

Can I make this ahead?

Yep! Assemble the fruit + topping separately, then sprinkle and bake when ready.

How do I store leftovers?

Fridge for 3–4 days. Reheat at 350°F for 10–15 minutes to revive the crisp topping.
