Honey Rhubarb Crisp Recipe with Brown Butter Oat Topping

We’re back with another crisp recipe, and this Honey Rhubarb Crisp is a springtime winner. Tart rhubarb is tossed in honey and a touch of orange, then baked under an oat-and-almond crumble flavored with almond extract and orange zest. The result is a balanced dessert — bright and tart, sweet and crunchy — that feels comforting and homemade.

This crisp hits the notes many of us love about fruit desserts: an easy, rustic topping and a juicy filling. You can use fresh or frozen rhubarb, and the recipe is forgiving enough to let kids help. Serve it warm with vanilla ice cream, whipped cream, or Greek yogurt for a simple, crowd-pleasing dessert.

What You Need for Rhubarb Crisp

• Chopped rhubarb: Fresh or frozen (thaw first).
• All-purpose flour: Helps thicken the filling and gives structure to the topping (can be swapped).
• Quick-cooking oats: Create a tender, crunchy crumble.
• Brown sugar: Adds sweetness and a caramel note to both filling and topping.
• Honey: Sweetens the filling and complements rhubarb’s tartness.
• Fresh orange juice and zest: Brightens the filling and topping with citrus acidity and aroma.
• Almond extract: A little goes a long way to deepen the flavor.
• Butter: For the topping to make a buttery crumble.
• Slivered almonds (optional): Add crunch and a nutty flavor to the topping.

When Is Rhubarb in Season?

Rhubarb is typically in season in spring, sometimes stretching into early summer depending on your region. In cooler climates it arrives a bit later in the season. If fresh rhubarb isn’t available, frozen chopped rhubarb works very well.

Can I Use Frozen Rhubarb?

Yes. Most supermarkets sell bags of frozen chopped rhubarb. Thaw it completely and drain any excess liquid if needed before mixing with the filling ingredients.

Ingredient Swaps

This crisp is easy to customize:

• Flour: Use whole wheat, almond flour, or a gluten-free blend if desired.
• Honey: Swap in maple syrup or agave nectar for a different sweetener.
• Almond extract: Omit or replace with vanilla extract for a more familiar flavor profile.
• Extra texture: Fold in chopped pecans, walnuts, or pumpkin seeds into the topping for added crunch.

Pro Tips for the Best Rhubarb Crisp

• If the topping hasn’t browned toward the end of baking, increase the oven temperature to 400ºF for a few minutes while watching closely.
• Don’t overwork the topping — you want a mix of small and larger clumps for the best texture.
• Allow the crisp to rest 10–15 minutes after baking so the filling sets slightly and is easier to serve.

Serving Suggestions

Serve the crisp warm for maximum appeal. Popular accompaniments include:

• Vanilla ice cream or frozen yogurt
• Lightly sweetened whipped cream
• Plain or honey-sweetened Greek yogurt

How to Store and Freeze Rhubarb Crisp

Store leftover crisp covered in the refrigerator for 3–5 days.

To freeze: cool completely, wrap tightly in plastic wrap and foil, and freeze up to 3 months. Thaw in the refrigerator overnight, then reheat at 350ºF for 20–30 minutes until heated through.

Honey Rhubarb Crisp — Recipe

This version yields about 12 servings. Prep time: 20 minutes. Bake time: 1 hour. Total time: 1 hour 20 minutes.

Servings: 12

Ingredients

Filling

• 6 cups chopped rhubarb (about 2 lbs)
• 3 tablespoons all-purpose flour (or substitute)
• 3 tablespoons quick-cooking oats
• 1 tablespoon packed brown sugar
• 1/4 cup honey
• 1 tablespoon fresh orange juice
• 1/2 teaspoon almond extract

Topping

• 1 1/2 cups quick-cooking oats
• 1/2 cup all-purpose flour
• 1/2 cup packed light brown sugar
• 1 teaspoon kosher salt
• 2 teaspoons orange zest
• 1 teaspoon almond extract
• 1/2 cup slivered almonds
• 8 tablespoons (1 stick) butter, softened

Instructions

1. Preheat the oven to 375ºF. Grease a 9×9-inch baking pan with butter or nonstick spray.
2. If using frozen rhubarb, thaw and drain any excess liquid. In a large bowl combine the rhubarb with the flour, oats, brown sugar, honey, orange juice, and almond extract. Toss until the rhubarb is evenly coated; set aside.
3. Make the topping by combining oats, flour, brown sugar, salt, orange zest, almond extract, and slivered almonds in a large bowl.
4. Add the softened butter and use a fork or your fingers to cut the butter into the dry ingredients until a crumbly mixture forms with clumps of varying sizes (about 3–4 minutes).
5. Spread the rhubarb filling into the prepared pan. Reserve about half the topping, then sprinkle the other half over the filling and press it gently into the rhubarb with a spatula. Top with the remaining crumble.
6. Bake for 30 minutes covered or until bubbling at the edges. Uncover and bake an additional 20–30 minutes, or until the topping is golden brown and the filling is bubbling. If the topping needs extra browning, raise the oven temperature to 400ºF for a few minutes while watching carefully.
7. Remove from the oven and let rest 10–15 minutes before serving. Serve warm with vanilla ice cream, whipped cream, or Greek yogurt.

Tips & Notes

• If the topping isn’t golden toward the end of the bake time, increase the oven to 400ºF and watch closely until browned.
• Letting the crisp rest after baking helps the filling thicken slightly and makes it easier to serve.
