• Sugar (1 cup): Balances the tartness and enhances flavor
• Tapioca (3.5 tbsp): Thickens the filling for a perfect consistency
• Raspberries (1.5 cups): Adds a pop of color and sweet-tart complexity
• Ground cinnamon (1/2 tsp): Warms up the fruit with subtle spice

For the Topping:

• All-purpose flour (1 1/4 cups): Forms the base of the crisp topping
• Oats (1.5 cups): Adds texture and a hearty crunch
• Brown sugar (1 cup): Provides rich sweetness and caramel notes
• Baking soda (1/4 tsp): Helps create a light, crumbly texture
• Salt (1/4 tsp): Enhances all the flavors
• Pecans (1/2 cup, chopped): Adds nuttiness and crunch
• Butter (3/4 cup, melted): Brings everything together into a golden, crispy topping

How to Make Sweet Pineapple Rhubarb Crisp

1. Prepare the Crisp Topping

In a large bowl, mix together the flour, oats, brown sugar, baking soda, salt, and cinnamon until evenly combined. Stir in the chopped pecans. Pour in the melted butter and mix with a fork until you get a crumbly texture with pea-sized pieces. Tip: Make sure the butter is cooled to room temperature—if it’s too hot, it can make the topping clump instead of crumble. Set aside.

2. Prepare the Fruit Filling

In another bowl, gently combine the rhubarb, crushed pineapple, sugar, tapioca, raspberries, and cinnamon. Let the mixture sit for about 15 minutes. This step is essential because it allows the tapioca to absorb juices and ensures your filling sets properly instead of becoming runny.

3. Assemble the Crisp

Preheat your oven to 350°F (175°C). Pour the fruit mixture into a 9×13-inch baking dish and spread it evenly. Sprinkle the prepared topping over the fruit, breaking up large clumps while keeping some small chunks for texture.

4. Bake to Perfection

Bake for about 45 minutes, or until the topping is golden brown and the filling is bubbling around the edges. You’ll know it’s ready when the top looks crisp and the fruit beneath is thick and glossy.

5. Cool and Serve

Let the crisp cool for at least 10 minutes before serving. This helps the filling set and makes it easier to scoop.

Tips for Success

• Let the fruit mixture rest before baking for the best texture
• Use fresh rhubarb when possible for brighter flavor
• Don’t skip the cooling time—it improves consistency
• Keep an eye on the topping; cover loosely with foil if it browns too quickly
• Chop pecans evenly for consistent crunch

Equipment Needed

• Large mixing bowls
• Measuring cups and spoons
• 9×13-inch baking dish (or similar)
• Fork or pastry cutter for the topping
• Oven

Recipe Variations

• Strawberry Twist: Replace raspberries with strawberries for a sweeter flavor
• Tropical Upgrade: Add shredded coconut to the topping for extra texture
• Low-Sugar Option: Reduce sugar and use naturally sweet pineapple juice
• Gluten-Free Version: Substitute flour with a gluten-free blend and certified GF oats
