Recipe Info

  • Prep Time: 25 minutes
  • Cook Time: 40 minutes
  • Total Time: 65 minutes
  • Yield: 8 servings

Ingredients

For the Fruit Filling:

  • 4 cups (about 1.5 lbs) fresh rhubarb, trimmed and cut into ½-inch pieces
  • 4 cups (about 1.5 lbs) fresh strawberries, hulled and quartered
  • ¾ cup granulated sugar (adjust to taste, depending on fruit sweetness)
  • ¼ cup cornstarch
  • 1 tablespoon fresh lemon juice
  • 1 teaspoon vanilla extract

For the Crisp Topping:

  • 1 ½ cups rolled oats (old-fashioned, not instant)
  • 1 cup all-purpose flour
  • ½ cup packed light brown sugar
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon salt
  • ½ cup (1 stick) cold vegan butter, cut into small cubes

Step-by-Step Instructions

  1. Prepare the Fruit Filling: Preheat your oven to 375°F (190°C). In a large bowl, combine the chopped rhubarb and quartered strawberries. Add the granulated sugar, cornstarch, lemon juice, and vanilla extract. Toss gently until the fruit is evenly coated. The cornstarch will help thicken the juices as it bakes.
  2. Assemble in Baking Dish: Pour the fruit mixture into a 9×13-inch baking dish or a similar 2-quart oven-safe dish. Spread it evenly across the bottom.
  3. Make the Crisp Topping: In a separate medium bowl, combine the rolled oats, all-purpose flour, brown sugar, cinnamon, and salt. Whisk them together until well mixed.
  4. Incorporate Vegan Butter: Add the cold, cubed vegan butter to the dry topping ingredients. Using your fingertips, a pastry blender, or a fork, work the butter into the dry mixture until it resembles coarse crumbs with some pea-sized pieces remaining. Avoid overworking the mixture; a crumbly texture is key.
  5. Top the Fruit: Sprinkle the prepared crisp topping evenly over the fruit mixture in the baking dish. Ensure the fruit is mostly covered.
  6. Bake the Crisp: Place the baking dish on a baking sheet (to catch any potential overflow) and bake in the preheated oven for 40-45 minutes. The crisp is done when the topping is golden brown and the fruit filling is bubbling thickly around the edges. The fruit should be tender when pierced with a fork.
  7. Cool and Serve: Remove the crisp from the oven and let it cool on a wire rack for at least 15-20 minutes before serving. This allows the filling to set and prevents it from being too runny.

Pro Tips for Success

  1. Don’t Overmix the Topping: When combining the vegan butter with the dry ingredients for the crisp topping, aim for a crumbly texture with visible pieces of butter. Overmixing can lead to a tough or less crumbly topping.
  2. Adjust Sugar to Fruit Sweetness: The sweetness of strawberries can vary. Taste a small piece of your strawberries before mixing the filling. If they are very sweet, you might reduce the sugar slightly. If they are tart, you might add an extra tablespoon or two.
  3. Use Fresh, Firm Rhubarb: For the best texture and flavor, choose rhubarb stalks that are firm, crisp, and free from blemishes. Avoid limp or stringy stalks.
  4. Let it Rest: While it’s tempting to dig in immediately, allowing the crisp to cool for at least 15-20 minutes after baking is crucial. This time allows the cornstarch to fully thicken the fruit juices, resulting in a perfectly set and less watery filling.

Variations & Substitutions

  • Gluten-Free Option: To make this crisp gluten-free, simply substitute the all-purpose flour in the topping with a 1:1 gluten-free all-purpose flour blend (ensure it contains xanthan gum) and use certified gluten-free rolled oats.
  • Other Fruit Combinations: While strawberry rhubarb is classic, feel free to experiment with other fruits. Peaches and blueberries, apples and cranberries, or a mix of various berries would also be delicious. Adjust sugar content based on the sweetness of your chosen fruits.
  • Spice It Up: For an extra layer of warmth, add a pinch of ground ginger or cardamom to the fruit filling, or a touch of nutmeg to the crisp topping.
  • Nutty Topping: For added crunch and flavor, incorporate ½ cup of chopped pecans or walnuts into the crisp topping mixture.

Serving Suggestions

This Vegan Strawberry Rhubarb Crisp is a delightful dessert on its own, but it truly shines when served warm with a scoop of creamy vegan vanilla ice cream. The cold, melting ice cream against the warm, bubbling fruit and crunchy topping is an unbeatable combination. Alternatively, a dollop of coconut whipped cream or a drizzle of vegan custard would also be exquisite. It’s perfect for a spring or summer gathering, a comforting weeknight treat, or a special occasion dessert.

Storage & Reheating

  • Fridge: Leftover crisp can be stored, covered tightly with plastic wrap or in an airtight container, in the refrigerator for 3-4 days.
  • Freezer: To freeze, allow the crisp to cool completely. Cover it tightly with plastic wrap and then aluminum foil, or transfer individual portions to freezer-safe containers. It can be frozen for up to 3 months. Thaw overnight in the refrigerator before reheating.
  • Reheating: To reheat, place individual servings in the microwave for 30-60 seconds, or warm larger portions in an oven preheated to 350°F (175°C) for 15-20 minutes, until heated through and the topping is crisp again.

Frequently Asked Questions

Q: Can I make this crisp ahead of time?

A: Yes, you can prepare the fruit filling and the crisp topping separately and store them in the refrigerator for up to 24 hours. Assemble and bake just before serving for the freshest results. You can also bake the entire crisp ahead of time and gently reheat it before serving.

Q: Why is my crisp topping soggy?

A: A soggy topping can occur if the crisp is underbaked, if there’s too much moisture in the fruit, or if it’s stored improperly. Ensure the crisp is baked until golden brown and bubbling. If your fruit is particularly juicy, you might add an extra tablespoon of cornstarch to the filling. Always let the crisp cool slightly before covering to prevent condensation.

Q: Can I use frozen strawberries or rhubarb?

A: Yes, you can use frozen fruit. Do not thaw the fruit before mixing with the other filling ingredients; add it directly to the dish. You may need to add an extra tablespoon of cornstarch to account for the additional moisture released by frozen fruit, and the baking time might be slightly longer.

Final Thoughts

This Vegan Strawberry Rhubarb Crisp is more than just a dessert; it’s an invitation to savor the simple, yet profound, pleasures of seasonal eating. With its vibrant flavors, comforting warmth, and delightful textures, it promises to be a memorable addition to your recipe repertoire.
