Ingredients and Necessary Utensils for Your Raspberry-Rhubarb Slab Pie
This section details the ingredients and equipment you’ll need to bake this delicious Raspberry-Rhubarb Slab Pie. Careful attention to quality ingredients will significantly impact the final flavor and texture. Investing in a few key utensils will also simplify the baking process and help you achieve the best possible results.
Crust Ingredients:
- 2 1/2 cups all-purpose flour (or gluten-free blend for a gluten-free option): Using high-quality flour ensures a tender and flaky crust.
- 1 teaspoon salt: Enhances the flavor of the crust.
- 1 cup (2 sticks) unsalted butter, chilled and cubed: Cold butter is crucial for a flaky crust. Use unsalted butter to control the salt level.

Filling Ingredients:
- 4 cups rhubarb, chopped (about 1 pound): Choose rhubarb that’s firm and not overly fibrous.
- 4 cups raspberries (fresh or frozen): Fresh raspberries offer the best flavor, but frozen work well in a pinch. If using frozen, ensure they’re fully thawed before adding them to the filling.
- 1 1/2 cups granulated sugar: Adjust this amount to your liking, depending on the sweetness of your fruit and personal preference.
- 1/4 cup cornstarch: Acts as a thickening agent for the filling.
- 1 tablespoon lemon juice: Brightens the flavors of the filling and prevents browning.
- 1 teaspoon vanilla extract: Adds depth and warmth to the filling.
- 1/4 teaspoon ground cinnamon (optional): Adds a subtle spice note.
Necessary Utensils:
- 9×13 inch baking pan: This is the standard size for a slab pie.
- Large bowl: For mixing the pie crust.
- Pastry blender or fork: To cut the butter into the flour.
- Measuring cups and spoons: Accurate measurements are essential for baking.
- Rolling pin: To roll out the pie crust.

Detailed Recipe Steps for Your Raspberry-Rhubarb Slab Pie
Follow these detailed steps to create your perfect Raspberry-Rhubarb Slab Pie. Take your time and enjoy the process; the delicious results are well worth the effort!
Making the Crust:
- In a large bowl, whisk together the flour and salt.
- Cut in the cold, cubed butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Work quickly to keep the butter cold.
- Gradually add the ice water, mixing until the dough just comes together. Do not overmix.
- Form the dough into a disc, wrap it in plastic wrap, and chill for at least 30 minutes. This allows the gluten to relax, resulting in a more tender crust.
- On a lightly floured surface, roll out half of the dough into a rectangle large enough to fit your 9×13 inch baking pan.
- Transfer the dough to the prepared pan, pressing it into the corners and trimming any excess.
Making the Filling:
- In a large bowl, combine the chopped rhubarb, raspberries, sugar, cornstarch, lemon juice, vanilla extract, and cinnamon (if using). Gently toss to coat the fruit evenly.
- Pour the filling into the prepared crust.
Topping and Baking:
- Roll out the remaining dough and either place it over the filling or cut it into strips to create a lattice top. Alternatively, for a simpler approach, you can skip a top crust entirely.
- Bake in a preheated oven at 375°F (190°C) for 45-55 minutes, or until the crust is golden brown and the filling is bubbly. If the crust starts to brown too quickly, loosely cover it with foil.
- Let the pie cool completely on a wire rack before cutting and serving. This allows the filling to set properly.
Tips and Variations for Your Raspberry-Rhubarb Slab Pie
Here are some tips and variations to enhance your Raspberry-Rhubarb Slab Pie experience. Experiment with different flavors and techniques to make it your own!
- For a sweeter pie: Increase the sugar to 1 ¾ cups or even 2 cups. Taste the filling before adding it to the crust to adjust to your preference.
- For a tarter pie: Add more rhubarb or reduce the amount of sugar.
- Add a streusel topping: Combine ½ cup flour, ½ cup brown sugar, ¼ cup oats, ¼ cup chopped nuts, and ¼ cup melted butter. Sprinkle over the filling before baking.
- Use a different type of berry: Blackberries, blueberries, or strawberries can be used in place of some or all of the raspberries.
- Make it vegan: Use a vegan butter substitute and a vegan egg replacement in the crust. Ensure your cornstarch is certified vegan.
- Make it gluten-free: Use a gluten-free all-purpose flour blend.
- Avoid overbaking: Overbaked pies will have a dry crust and possibly a burnt filling. Keep a close eye on it during the last 15 minutes of baking.
- Let it cool completely: This allows the filling to set properly. Slices will hold their shape better and be less messy.
