Discover the Magic of Fresh Rhubarb Desserts
Have you ever ventured into making a fresh rhubarb dessert? Many find it surprisingly simple, especially when paired with other fruits like apples or strawberries. We recently found some vibrant fresh rhubarb and were inspired to create this apple rhubarb crisp. It’s a dessert that brings a unique tanginess, a welcome contrast to overly sweet treats, and pairs wonderfully with the natural sweetness of apples.
Rhubarb seems to be one of those nostalgic ingredients, perhaps more commonly used by previous generations. I remember my Grandmother incorporating it into everything from pies to savory dishes. These days, finding fresh rhubarb in local grocery stores, especially in rural areas, can be a bit of a treasure hunt! That’s why this year, we decided to take matters into our own hands and are successfully growing fresh rhubarb right in our garden. It’s incredibly rewarding to harvest your own ingredients for such a cherished recipe.
Using Frozen Rhubarb for Year-Round Enjoyment
While fresh rhubarb offers the best texture and flavor, its season can be short. Don’t worry if fresh isn’t available; you can absolutely use frozen rhubarb! When using frozen, be aware that it will release more liquid as it thaws, which can affect the final texture of your crisp. To achieve the best results, place the frozen rhubarb in a bowl on the counter for about 1.5 to 2 hours to thaw completely. Once thawed, make sure to drain all the excess liquid thoroughly before measuring and incorporating it into your recipe. This crucial step prevents a watery crisp and helps maintain the desired consistency.
Essential Ingredients for Your Perfect Crisp
Crafting the perfect apple rhubarb crisp starts with selecting the right ingredients. Here’s a closer look at what you’ll need and some tips for each:
- Rhubarb: For optimal flavor and texture, fresh rhubarb is always our top recommendation. However, as mentioned, frozen can be used if properly thawed and drained. The vibrant red stalks often indicate a sweeter, riper flavor, though green stalks are perfectly safe to eat and just require a bit more sugar.
- Apples: Peeled and diced apples provide a lovely sweetness and complementary texture. We prefer Fuji apples for their delightful balance of sweetness and firmness, which holds up well during baking. If you lean towards a tarter crisp, Granny Smith apples are an excellent choice.
- Sugar: Rhubarb is naturally quite tart, so granulated white sugar is essential to balance the flavors. Depending on your preference, you can adjust the amount, with a full cup yielding a sweeter crisp.
- Butter: Whether you choose salted or unsalted butter, it plays a vital role in creating a rich, creamy fruit filling. We often opt for salted butter, like Kerrygold, for that extra depth of flavor that complements the fruit beautifully.
- All-Purpose Flour: This is a key ingredient for both the fruit filling (to help thicken) and the crisp, crumbly topping.
- Old-Fashioned Oats: Crucial for the “crisp” in apple rhubarb crisp, old-fashioned oats provide a wonderful texture and a wholesome chewiness. Avoid quick-cooking oats, as they can become mushy.
- Cornstarch (or Arrowroot Flour): To ensure a perfectly thick and luscious fruit sauce, a thickening agent is necessary. Cornstarch is a common choice, but arrowroot flour is a fantastic gluten-free alternative.
- Brown Sugar & Cinnamon: These two ingredients are critical for the oatmeal topping, adding a warm, caramel-like sweetness and inviting aroma that makes the crisp truly irresistible.
Delicious Variations to Customize Your Crisp
One of the joys of baking is the ability to customize recipes to suit different tastes or dietary needs. Our apple rhubarb crisp is wonderfully adaptable:
- Dairy-Free Option: Simply swap out traditional butter for a high-quality vegan plant-based butter product. The crisp will be just as delicious and suitable for those with lactose intolerance or dairy allergies.
- Sugar-Free Alternative: If you’re managing sugar intake, you can use a brown sugar substitute like Splenda brown sugar blend to sweeten both the fruit filling and the topping.
- Fruit Combinations: While apples and rhubarb are a classic pairing, feel free to experiment with other fruits. Strawberries pair exceptionally well with rhubarb, creating a vibrant “strawberry rhubarb crisp.” Blueberries or raspberries could also be lovely additions. For best texture, we still recommend including a firm apple variety like Fuji or Granny Smith, similar to how versatile our huckleberry cobbler is.
- Nutty Topping: For an extra layer of crunch and flavor, consider adding chopped nuts like pecans or walnuts to your oatmeal topping mixture.
- Spice It Up: Beyond cinnamon, a pinch of nutmeg or cardamom can add delightful warmth and complexity to the fruit filling.
Do You Need to Peel Rhubarb Before Cooking It?
A common question when preparing rhubarb is whether or not to peel it. The simple answer is no, it’s not necessary. While some cooks prefer to lightly peel the outer layer of rhubarb stalks, much like you might with celery, we generally skip this step for our crisp recipe. The skin softens beautifully during baking and adds to the rustic charm and fiber content of the dessert. So, save yourself some time and effort – no peeling required!
Baking Time and Tips for a Perfect Crisp
Achieving that ideal balance of tender, bubbling fruit and a golden, crunchy topping is key to a perfect crisp. Once you’ve assembled your apple rhubarb crisp, it will need to bake in the oven for approximately 40 to 45 minutes, or until the fruit is fork-tender and the topping has turned a beautiful golden brown. You can easily test the fruit’s doneness by carefully pulling out a small piece with a fork near the end of the baking time.
It’s crucial to allow the crisp to cool on a wire rack for at least 15 minutes after removing it from the oven. This cooling period is vital for the fruit filling to set and thicken properly, preventing a runny dessert. Patience is a virtue when it comes to serving crisp!
Serving Suggestions for Your Rhubarb Masterpiece
This apple rhubarb crisp is truly versatile, making it suitable for various occasions and serving styles. We love serving it warm, fresh from the oven, with a generous scoop of vanilla ice cream melting decadently over the top. The contrast between the warm, tart fruit, the crunchy topping, and the cold, creamy ice cream is simply divine.
But the possibilities don’t stop there! Consider these serving ideas:
- For Brunch or Breakfast: Enjoy a smaller portion with a dollop of Greek yogurt for a wholesome start to your day.
- With Whipped Cream: A cloud of freshly whipped cream is another excellent accompaniment, adding a lighter, airy texture.
- Custard or Crème Anglaise: For an elegant touch, serve it with a smooth vanilla custard or crème anglaise.
- Plain and Simple: Sometimes, the crisp is perfect on its own, allowing the pure flavors of the fruit and topping to shine.

Frequently Asked Questions About Rhubarb Crisp
Can I substitute frozen rhubarb for fresh rhubarb in a crisp?
Absolutely! While fresh rhubarb generally offers a slightly firmer texture and brighter flavor, frozen rhubarb is a perfectly acceptable substitute, especially when fresh is out of season. You can approach this in two ways: either purchase pre-frozen rhubarb from the store or freeze your own fresh rhubarb during its peak season. If you freeze it yourself, slice it into desired pieces and store in freezer bags. When using frozen rhubarb for your crisp, remember to thaw it completely and drain any excess liquid before adding it to the recipe. This step is crucial to prevent your crisp from becoming watery.
What happens if rhubarb is green? Is it safe to eat?
Yes, green rhubarb is safe to eat! The color of rhubarb stalks can vary depending on the variety and how much sun exposure it received during growth. Green rhubarb typically means it’s less ripe or is a variety that naturally stays greener. It will usually be tarter than its red counterparts, so you might want to adjust the sugar content in your recipe to achieve your desired sweetness level. Don’t let the green color deter you from enjoying this wonderful ingredient!
Can I make apple rhubarb crisp ahead of time?
You can certainly prepare parts of the crisp ahead of time. You can mix the fruit filling and store it in the refrigerator for up to a day. The crisp topping can also be made and stored in the refrigerator for a few days, or even frozen for longer storage. However, for the best texture and crunch, it’s always recommended to assemble and bake the crisp fresh on the day you plan to serve it. Baking it fresh ensures the topping remains perfectly crisp and the fruit filling is warm and bubbly.
How should I store leftover apple rhubarb crisp?
Leftover apple rhubarb crisp should be covered tightly with plastic wrap or aluminum foil and stored in the refrigerator. It will typically last for 3-4 days. To reheat, you can warm individual servings in the microwave or place the entire pan back in a preheated oven at 350°F (175°C) for 15-20 minutes, or until warmed through and the topping is crisp again. Reheating in the oven helps restore the crispness of the topping.
With its delightful combination of tart rhubarb and sweet apples, crowned with a golden, crunchy oat topping, this Apple Rhubarb Crisp is more than just a dessert – it’s a comforting experience. We hope this comprehensive guide inspires you to create this incredible treat in your own kitchen. Enjoy the process, and savor every delicious bite!
