Perfect for spreading on toast, mixing into yogurt, spooning over pancakes, or swirling into desserts, this versatile rhubarb spread can transform everyday meals into something special.

What Is Rhubarb Butter?

Rhubarb butter is a smooth, fruit-based spread made by gently simmering rhubarb with sugar, water, and flavor enhancers like lemon juice or vanilla. The mixture is cooked down into a thick, luscious consistency, similar to fruit preserves or apple butter, but with rhubarb’s distinctive tartness and vibrant color. Unlike jams and jellies, fruit butters don’t require pectin, making them easier to prepare and perfect for small-batch cooking.

This rhubarb butter recipe uses fresh or frozen rhubarb, making it accessible year-round. The end result is a glossy, magenta-hued spread that’s bold in flavor yet smooth in texture—perfect for breakfast, snacks, or even savory pairings.

Homemade Rhubarb Butter Recipe

Ingredient List

  • 4 cups chopped rhubarb – fresh or frozen

  • 1/2 cup granulated sugar – adjust depending on the tartness of your rhubarb

  • 1/4 cup water – helps the rhubarb cook evenly and break down

  • 1 teaspoon lemon juice – enhances brightness and preserves color

  • 1/2 teaspoon vanilla extract (optional) – adds warmth and depth

Ingredient Tips

  • Use trimmed rhubarb stalks and avoid the leaves, which are toxic.

  • If using frozen rhubarb, there’s no need to thaw before cooking.

  • Adjust the sugar to taste—start with less and add more after cooking if needed.

  • Fresh lemon juice is preferred for a cleaner citrus flavor.

  • Vanilla extract is optional but enhances the overall richness of the spread.

How to Make Rhubarb Butter

Making rhubarb butter is a straightforward process that takes less than 30 minutes from start to finish. You don’t need any special equipment—just a saucepan and a blender if you prefer a smoother texture.

Step-by-Step Instructions

Step 1: Combine Ingredients
In a medium saucepan, add the chopped rhubarb, sugar, and water. Stir to combine. Set the pan over medium heat and bring the mixture to a simmer.

Step 2: Simmer Until Tender
Let the rhubarb mixture cook gently for about 15 to 20 minutes, stirring occasionally. The rhubarb should break down into soft fibers and begin to form a thick, jammy consistency. Stir regularly to avoid burning and ensure even cooking.

Step 3: Add Flavor Enhancers
Once the rhubarb is fully softened, stir in the lemon juice and vanilla extract if using. These additions balance the sweetness and elevate the flavor profile with subtle complexity.

Step 4: Blend for a Smooth Texture (Optional)
If you prefer your rhubarb butter silky smooth, use an immersion blender directly in the pot to puree the mixture. You can also transfer it to a countertop blender or food processor. Be cautious when blending hot liquids—allow the mixture to cool slightly before blending and blend in small batches if needed.

Step 5: Cool and Store
Allow the finished rhubarb butter to cool to room temperature. Transfer it to a clean glass jar or airtight container. Refrigerate for up to 2 weeks. For long-term storage, freeze in small portions for up to 3 months.

How to Use Rhubarb Butter

One of the best things about rhubarb butter is its incredible versatility. This sweet-tart spread can be used in countless ways across breakfast, snacks, desserts, and even savory dishes.

Expert Tips for the Best Rhubarb Butter

To make the best possible batch of rhubarb butter, keep these practical tips in mind:

  • Cook low and slow to develop richer flavor and a smoother texture.

  • Adjust sugar to taste depending on the tartness of your rhubarb variety.

  • Use a non-reactive saucepan such as stainless steel or enamel-coated cookware to prevent metallic flavors.

  • Don’t skip the lemon juice—it balances the tartness and preserves the color.

  • For a chunkier texture, skip the blending step and enjoy it rustic-style.

Frequently Asked Questions

Can I use frozen rhubarb?
Absolutely. Frozen rhubarb works just as well as fresh. There’s no need to thaw it before cooking, although you may need to extend the cooking time slightly to account for the extra moisture.

Is this recipe suitable for canning?
No, this particular recipe isn’t formulated for canning. Because it’s low in sugar and acidity, it doesn’t meet safe canning guidelines. For shelf-stable rhubarb preserves, use a tested canning recipe from a trusted source like the Ball Canning Guide or USDA.

Can I make a sugar-free version?
You can try using alternative sweeteners like stevia or monk fruit, though the final texture and taste may vary. Keep in mind that sugar also acts as a preservative, so sugar-free versions may spoil more quickly.

In the refrigerator, rhubarb butter lasts up to 2 weeks. In the freezer, it will keep for up to 3 months.
