Ingredients and Measurements

• 3 cups rhubarb cut into small pieces
• 3 cups strawberries cut into small pieces
• 1 cup sugar
• 1 ⅓ cups flour divided
• 1/2 teaspoon cinnamon
• 1 cup brown sugar
• 1 cup old fashioned oats
• 1/4 teaspoon nutmeg
• 1/2 cup butter melted

How to Assemble and Bake

1. Preheat oven to 350°F and grease a 9×13-inch baking dish with nonstick spray or butter.
2. Wash rhubarb, trim ends and discard leaves, then cut stalks into small even pieces.
3. Remove strawberry stems and roughly chop strawberries to match the size of the rhubarb.

4. In a large bowl, toss rhubarb, strawberries, sugar, 1/3 cup flour, and cinnamon until evenly coated.

5. Let the sugared fruit sit briefly to macerate and release juices.
6. Spread the fruit mixture evenly into the prepared baking dish.

10. Bake uncovered at 350°F for 35–40 minutes, until the topping is golden brown and the fruit is bubbling around the edges.
11. If the topping browns too quickly, lightly tent with foil and continue baking until done.

12. Let the crisp rest for 10–15 minutes to thicken before serving.

    

Quick Tips for Perfect Texture

• Make sure you use equal amounts of rhubarb and strawberries, cutting both into small, similar-sized pieces. This ensures everything cooks evenly and you get a well-balanced bite every time.
• Let the sugared fruit sit for a bit before baking to macerate. This softens the fruit and helps release its juices, making the filling juicy and tender.
• Add flour (or you could try cornstarch) to the fruit mixture to thicken those juices during baking—otherwise, you’ll end up with a runny mess. This recipe calls for about 1/3 cup flour in the filling.
• When you spread the oat topping, press down lightly to help it adhere to the fruit below so it stays crunchy and doesn’t fall apart when serving.
• Bake at 350°F until golden and bubbly around the edges, which usually takes 35–40 minutes. If the topping starts browning too fast, lightly cover it with foil partway through baking to protect it.
• After baking, let the crisp rest for 10–15 minutes before serving. This step thickens the filling and makes it easier to scoop into perfect servings.
• To keep the topping crisp after storing leftovers, let the crisp cool completely before covering. If the topping softens in the fridge, just pop it back in a hot oven at 350°F for 8–12 minutes to crisp it up again.
• If you’re using frozen fruit, be sure to thaw it first and drain off any extra liquid—similar to how we handle syrupy fillings in our Easy Peach Cobbler with Canned Peaches. Adding an extra tablespoon or two of flour or cornstarch helps absorb the moisture and keep the filling just right.
• Remember to always trim away and discard the rhubarb leaves—they aren’t edible and could be harmful. Only the stalks go into the dish.

Flavor Swaps and Add-Ins

• Berry swaps: Try swapping some or all of the strawberries for blueberries, raspberries, or blackberries. A mixed berry and rhubarb crisp is just as delicious and adds color and flavor variety.
• Nutty topping: Stir in a half cup of chopped pecans or walnuts to the oat topping for extra crunch and a nutty twist your family will love. Pistachios are lovely too—see this Rhubarb Rose Upside-Down Cake with Pistachio Crumb for inspiration.
• Gluten-free: Use certified gluten-free oats and swap the all-purpose flour for almond flour or a gluten-free blend in both the filling and topping to keep it safe for gluten sensitivities.
• Less sugar: If your strawberries are very sweet, you can reduce the sugar in the filling by 1/4 to 1/2 cup. Alternatively, use coconut sugar or a sugar substitute—just adjust the amount to your preference.
• Vegan: Replace the butter with coconut oil or any vegan butter alternative. You can also swap the sugar for maple syrup or coconut sugar for a plant-based version.
• Flavor boosts: Brighten the filling with a teaspoon of lemon zest (orange is fantastic with rhubarb too—see this Rhubarb & Orange Frangipane Galette) or add a dash of cardamom. For a different aroma, stir 1/2 teaspoon of vanilla or almond extract into the topping.
• Individual servings: Want to make this for a smaller group or just yourself? Bake the crisp in 4–6 small ramekins. Just shorten the bake time a bit and watch for bubbling and a golden topping.

Serving, Storing, and Reheating

How to serve: This dessert can spread out a bit when you dish it up, so I like to serve it in shallow tart dishes that have flat bottoms and low sides to keep it neat. It’s even better with a big scoop of vanilla ice cream, freshly whipped cream, or a warm pour of creamy egg custard—trust me, that combo is heavenly!

Storage: Crisps tend to lose their crunch when covered tightly, so I recommend leaving this dessert on the counter up to 2 days, loosely covered with a paper towel and plastic wrap to help maintain the topping’s texture.

Can you freeze a fruit crisp?

Absolutely! Fruit crisps freeze beautifully. Just let the dessert cool completely, then wrap it tightly with two layers of plastic wrap and aluminum foil. You can freeze it for up to 6 months. When you’re ready to enjoy, thaw it and bake until the topping crisps up again. Perfect for busy days!

Answers to Common Questions

• Q: Can I use frozen strawberries or rhubarb? A: Yes, you definitely can! Just make sure to thaw them completely and drain off any extra liquid before putting together your crisp. You might want to add an extra tablespoon or two of flour or cornstarch to help thicken the filling, and the bake time might be a little longer.
• Q: How do I keep the topping crisp? A: Baking uncovered helps keep that crunch. After baking, let the crisp cool completely before covering it loosely. Avoid sealing it tightly while it’s still warm. If leftovers soften, just reheat in a 350°F oven for about 8–12 minutes to bring back that crunch.
• Q: Can I make this ahead of time? A: Absolutely! You can prep the fruit filling and topping separately and keep them in the fridge for up to 24 hours before baking. Or assemble the whole crisp and freeze it well wrapped for up to 6 months. When ready, thaw and bake until the topping crisps again.
• Q: How do I know when the crisp is done? A: Look for a golden-brown topping and bubbling fruit filling around the edges. If the center still looks too liquidy, just pop it back in for a few more minutes.
• Q: Are rhubarb leaves safe to eat? A: No. Rhubarb leaves are not edible and should always be trimmed off and discarded. Only use the stalks in your recipes.
• Q: Can I halve or scale this recipe? A: Yes! Just halve the ingredients and bake in an 8×8-inch dish or use smaller individual ramekins. Adjust baking time as needed and keep an eye out for bubbling fruit and a golden top.
