• Crowd Pleaser: Whether it’s a family meal or a potluck, this crisp vanishes quickly and always brings a smile.

Ingredients You’ll Need

• Rhubarb: Go for bright to deep red stalks. They deliver the best color and flavor—avoid any leafy parts (they’re toxic!). Provides that signature tartness and lovely juiciness when baked.
• Strawberries: Fresh, ripe, and preferably local if you can find them. Lends sweetness, balancing the rhubarb’s tart edge.
• Lemon Juice: Just a little brings out all the fruity notes and keeps the colors vibrant.
• Granulated Sugar: Sweetens and helps macerate the fruit, pulling out those luscious juices.
• Cornstarch: Essential for thickening the filling so it doesn’t run all over your plate.
• Brown Sugar: Adds deep, caramel-like sweetness to the topping.
• All-Purpose Flour: Gives body to the oat crumble, ensuring it bakes up crispy.
• Old Fashioned Rolled Oats: Not instant! You need those hearty flakes for real crunch and texture.
• Cinnamon: For a gentle warmth that pairs beautifully with both fruits.
• Kosher Salt: Enhances all the flavors, don’t skip it.
• Unsalted Butter: Don’t melt it—softened gives the perfect crumbly texture.
• Vegetable Oil: Helps create those gloriously golden bits on top.

If you’re wondering if you must cut the fruit a certain way—don’t stress. Keeping things even helps it bake uniformly, but perfection is not the point here.

Variations

Love to play with your food a bit? Here are a few ways to change it up:

• Mix Up the Fruit: Add raspberries, blueberries, or even blackberries for an extra punch of color and flavor.
• Nutty Crunch: Stir in a handful of chopped pecans or walnuts into the topping for added crunch and a toasty note.
• Spice Things Up: Try a touch of ginger or cardamom in the topping for a new flavor twist.
• Lower Sugar: Cut down the sugar slightly if your fruit is already super sweet, or swap some for honey or maple syrup (just watch the consistency).
• Gluten-Free: Use a gluten-free flour blend and certified gluten-free oats to suit dietary needs.

How to Make Strawberry Rhubarb Crisp

Step 1: Prep Your Oven and Dish

Start by heating the oven to 375°F and positioning a rack in the center. Take out a 9” x 13” baking dish—no need for greasing.

Step 2: Make the Filling

In a big bowl, toss together the sliced rhubarb, chopped strawberries, and lemon juice until the fruit is glistening. Sprinkle in the sugar, stir to combine, then dust the top with cornstarch, making sure to incorporate it fully so you don’t get chalky bites. Pour the whole mixture, juices and all, into your prepared baking dish and gently spread it out.

Step 3: Whip Up the Topping

In a separate medium bowl, add your brown sugar, flour, rolled oats, cinnamon, salt, butter (softened, not melted!), and vegetable oil. Use a pastry cutter or your fingertips to blend it all together until shaggy crumbs form—big clumps are not only okay, they’re encouraged.

Step 4: Assemble and Bake

Scatter the crumbly topping evenly over the fruit filling, leaving about an inch around the edges exposed (this gets beautifully caramelized). Resist the urge to press or smooth out the topping—rugged clumps bake up into the best crunchy bites.

Slide the pan into the oven and bake for 45–50 minutes. You’re looking for thick, bubbling fruit around the sides and a topping that’s browned and crisp. If the top is browning too fast, lightly cover with foil.

Step 5: Cool and Serve

Allow the crisp to rest on a cooling rack for 15 minutes before serving. This lets the filling thicken just enough to spoon neatly.

Pro Tips for Making the Recipe

• Even Slices Matter: Cut rhubarb and strawberries into similar-sized pieces so everything softens evenly.
• Watch the Topping: Don’t be afraid if it looks too crumbly going in—rough texture equals crispy bites.
• Butter Consistency: Room temperature butter (not melted, not cold) is key for blending the topping easily.
• Bubbling is Your Sign: Bake until the filling really bubbles—this means the cornstarch is doing its job and thickening up the juices.
• Don’t Cover Up: Let the crisp cool uncovered so the topping stays crunchy (avoid sogginess at all costs!).

How to Serve

Strawberry Rhubarb Crisp absolutely shines when it’s still a bit warm from the oven. Offer generous scoops in shallow bowls, and—this is my strong recommendation—pile on some creamy vanilla ice cream or lightly sweetened whipped cream. If you’re serving guests, a drizzle of heavy cream is also delightful. Pair with freshly brewed coffee or a summery iced tea for a satisfying dessert at any gathering!

Make Ahead and Storage

Storing Leftovers

Leave the crisp uncovered at room temperature for up to two days. This keeps the topping as crunchy as possible. After two days, cover with foil or a tight lid and refrigerate.

Freezing

Strawberry Rhubarb Crisp actually freezes fairly well. Let it cool completely, wrap tightly, and store in the freezer for up to three months. Thaw overnight in the fridge before reheating.

Reheating

To bring back the just-baked texture, reheat portions in a 350°F oven for 10–15 minutes (covered loosely with foil); or, use the microwave in 20–30 second bursts for a quick dessert fix (the topping may soften a little).

FAQs

Can I use frozen rhubarb or strawberries instead of fresh?
Absolutely! Just be sure to thaw and drain off excess liquid so your crisp doesn’t turn soupy. You may want to add a touch more cornstarch for frozen fruit to help thicken things up.

What if my rhubarb is green instead of red?
While red stalks look more festive, greenish rhubarb is perfectly safe and still tasty—just a bit more tart. If you want a sweeter end result, consider increasing the sugar a touch or using especially ripe strawberries.

Can I make this ahead for a party?
Definitely! Assemble it earlier in the day, store in the fridge, and bake just before serving. You can also bake it the night before and gently reheat before guests arrive.

Why is my crisp topping soggy?
This most often happens if the pan is covered while still warm or if it was stored before cooling fully. Always cool it uncovered, and don’t stress—just pop it in the oven for a bit to crisp up again.
