Ingredients

1 pound fresh rhubarb, cut into 1/2 inch pieces
1 pound fresh strawberries, sliced
3/4 cup granulated sugar
2 tablespoons cornstarch
2 teaspoons lemon juice
1 teaspoon vanilla extract
1/8 teaspoon salt

For the Brown Butter Streusel

1/2 cup butter
3/4 cup all-purpose flour
3/4 cup old-fashioned oats
3/4 cup packed brown sugar
1 teaspoon ground cinnamon
1/8 teaspoon salt

Ingredient Notes and Easy Substitutions

Rhubarb: Fresh rhubarb is crucial for the right tartness. If you can’t find it, frozen rhubarb can be used; just thaw and drain excess moisture before combining it with the other ingredients.
Strawberries: Feel free to substitute strawberries with other berries such as blueberries or blackberries for a fun twist.
Cornstarch: This is necessary for thickening the fruit filling. If you need a substitute, you can use arrowroot powder, but keep an eye on the texture of your filling.
Brown Sugar: Light or dark brown sugar will work, but dark brown sugar will add a richer flavor due to its higher molasses content.
Butter: For a dairy-free option, you can use a plant-based butter or coconut oil, although the flavor will differ slightly.

Instructions

Brown the Butter: Melt the butter in a small saucepan over medium heat. Stir frequently until it turns golden brown and you see tiny brown bits forming at the bottom—this will take about 5 to 7 minutes. Remove it from heat and let it cool slightly in the refrigerator.
Preheat the Oven: Set your oven to 350°F (175°C) so it’s ready for baking.
Prepare the Fruit: In an 8-9 inch skillet or baking dish, mix the rhubarb, sliced strawberries, granulated sugar, cornstarch, lemon juice, vanilla extract, and salt until well combined.
Make the Streusel: In a mixing bowl, combine the flour, oats, brown sugar, cinnamon, and 1/8 teaspoon of salt. Pour in the cooled brown butter and mix until the mixture is crumbly.
Assemble the Crisp: Sprinkle the streusel evenly over the fruit mixture in the baking dish.
Bake: Place the dish on a parchment-lined baking sheet to catch any drips and bake for about 40-45 minutes, or until the filling is bubbling and the topping is golden brown.
Cool and Serve: Allow the crisp to cool for about one hour before serving. This cooling time helps the filling set up nicely. Serve warm with a scoop of vanilla ice cream for an extra treat.

Expert Tips for the Best Results

Don’t skip the cooling: Letting the crisp cool before serving allows the filling to thicken, making it easier to serve.
Check for bubbling: The filling should be visibly bubbling around the edges; this indicates it’s cooked through.
Presentation matters: To make it visually appealing, consider serving it in individual ramekins instead of one big dish.
Use parchment paper: This makes for easy clean-up and prevents sticky messes during baking.

Variations

Peach Addition: Combine peaches with the strawberries for a different fruity flavor.
Nutty Streusel: Add chopped nuts like pecans or walnuts to the streusel for added crunch.
Spicy Twist: Incorporate a pinch of nutmeg or cardamom into the streusel for a warm, spiced flavor profile.
Coconut Flakes: Mix in unsweetened coconut flakes into the streusel for a tropical twist.
Maple Sweetener: Instead of granulated sugar, use maple syrup to sweeten the fruit for a different taste.

Serving Suggestions

The Brown Butter Streusel Strawberry Rhubarb Crisp is delightful on its own but can be enhanced with various accompaniments.

Ice Cream: Vanilla or caramel ice cream will add a creamy balance to the tart flavors.
Whipped Cream: Lightly sweetened whipped cream is a classic topping that complements the crisp beautifully.
Custard: Serve with a warm vanilla custard for an indulgent treat.
Beverages: Pair with a chilled glass of sparkling water or a sweet iced tea for a refreshing contrast.

Storage and Reheating

To store leftovers, let the crisp cool completely, then cover it tightly with plastic wrap or foil. It will keep in the refrigerator for up to 3-5 days. To reheat, place in a 350°F (175°C) oven until warmed through, about 15-20 minutes. The crisp can also be enjoyed cold for breakfast or a late-night snack!

If you want to make it ahead of time, it can be assembled a day in advance. Just bake it on the day you plan to serve it for the best flavor.

Common Mistakes to Avoid

Soggy Bottom: Ensure the cornstarch is thoroughly mixed with the fruit mixture; this will help thicken the juices as they cook.
Not Cooling Enough: Skipping the cooling period can result in a runny filling, making it difficult to serve.
Baking Time: Keep an eye on the crisp; every oven varies, and baking time may differ.
