Easy Rhubarb Tart

Growing up, I’d never even heard of rhubarb until my neighbor offered me a slice of her homemade pie. All I knew was that those red stalks in her garden looked like pink celery, and I wasn’t sure what to make of them. The first bite changed everything – sweet, tart, and completely different from anything I’d tasted before.

Years later, I’ve figured out that making a rhubarb tart doesn’t need to be complicated. While my first attempts were hit-or-miss (mostly miss), I’ve learned that the secret lies in balancing the natural tartness of rhubarb with just the right amount of sugar. Now it’s become one of those spring recipes I look forward to making as soon as I spot those familiar stalks at the market.

What Kind of Rhubarb Should I Use?

For the best tasting tart, look for fresh rhubarb stalks that are firm and crisp, with a bright pink to deep red color. While both green and red rhubarb varieties will work in this recipe, the red stalks tend to give your tart a prettier color and slightly sweeter flavor. The thinner stalks are usually more tender and less stringy than the thicker ones, making them perfect for baking. If fresh rhubarb isn’t in season, frozen rhubarb works just fine – just thaw it completely and drain off any excess liquid before using it in your tart.

Options for Substitutions

Here are some helpful swaps if you need to make adjustments to this tart recipe:

• Rhubarb: If rhubarb isn’t in season, you can use tart apples or strawberries instead. For apples, cook them a bit longer and add a splash of lemon juice to mimic rhubarb’s tartness. With strawberries, reduce the sugar to 1/3 cup since they’re naturally sweeter.
• Cornflour: Regular all-purpose flour or arrowroot powder work well as thickeners here. Use the same amount if using arrowroot, but double the quantity if using all-purpose flour.
• Cardamom: No cardamom? Try using cinnamon or a mix of cinnamon and ginger powder. Start with 1/4 teaspoon and adjust to taste.
• White sugar: Brown sugar or coconut sugar can work too, though they’ll give a slightly different flavor and color to the filling. Keep the measurements the same.
• Whipped cream: You can swap this for vanilla ice cream, Greek yogurt, or coconut whipped cream if you’re looking for a dairy-free option.

Watch Out for These Mistakes While Baking

The biggest challenge when working with rhubarb is managing its moisture content – cutting the stalks too small can lead to a soupy filling, while pieces that are too large won’t cook evenly, so aim for 1-inch chunks for the perfect texture.

Many bakers skip the crucial step of letting the cut rhubarb sit with sugar for 15-20 minutes before cooking, but this process helps draw out excess moisture and ensures your tart filling won’t be too wet or too dry.

Temperature control is essential – cooking the filling over too high heat can cause the cornflour to clump or the rhubarb to break down completely, so maintain a medium heat and stir constantly until the mixture just starts to thicken.

For the best results, let your filled tarts cool completely before adding whipped cream, as the residual heat can cause the cream to melt and make your dessert look messy.

What to Serve With Rhubarb Tart?

These sweet-tart little treats are perfect with a dollop of vanilla ice cream or freshly whipped cream on top – though I see you’ve already thought of that! A nice cup of afternoon tea or coffee makes these tarts feel extra special, and I particularly like Earl Grey tea since its subtle bergamot flavor plays nicely with the rhubarb. If you’re serving these for dessert after dinner, consider adding a small scoop of cream cheese ice cream on the side, which adds a lovely tangy contrast to the sweet-tart rhubarb filling. For brunch, these tarts are lovely with a glass of prosecco or champagne, making them feel extra festive.

Storage Instructions

Keep Fresh: Once filled, these rhubarb tarts are best enjoyed within 24 hours to maintain that perfect crispy crust. You can keep them in the fridge in an airtight container, but wait to add the whipped cream and mint until right before serving.

Make Ahead: Good news – you can prep components separately! The rhubarb filling can be made up to 3 days ahead and stored in the fridge. The baked tart shells will stay fresh for 2 days when kept in an airtight container at room temperature. Just assemble when you’re ready to serve.

Save: If you have leftover filling, spoon it into a jar and keep it in the fridge for up to a week. It’s great on toast, stirred into yogurt, or saved for your next batch of tarts. The filled tarts don’t freeze well, as the pastry gets soggy when thawed.

• Calories: 1800-2000
• Protein: 10-15 g
• Fat: 70-80 g
• Carbohydrates: 290-320 g

Ingredients

For the compote:

• 1/2 tsp cardamom powder (freshly ground for best aroma)
• 1 lb rhubarb (chopped into 1/2-inch pieces)
• 1 tbsp cornflour
• 1/2 cup sugar (granulated white sugar)

For the assembly:

• 12 baked tart shells (2-inch each)
• mint leaves (optional, for garnish)
• whipped cream (I like Reddi-wip for convenience)

Step 1: Prepare the Rhubarb

Begin by chopping 1 pound of rhubarb stalks, which should yield approximately 3 cups of chopped rhubarb.

Make sure the pieces are chopped evenly for consistent cooking.

Step 2: Cook the Rhubarb Compote

Place the chopped rhubarb into a small saucepan and add sugar, cornstarch, and cardamom.

Cook over medium heat, stirring occasionally, until the rhubarb breaks down and the mixture thickens, about 5 minutes.

Once cooked, set the mixture aside to cool for a bit before refrigerating.

Step 3: Chill the Compote

Once the rhubarb compote has cooled, refrigerate it for at least 2 hours to allow the flavors to meld and the compote to thicken further.

It can be stored in the refrigerator for up to 3 days if needed.

Step 4: Assemble the Tarts

When ready to serve, divide the chilled rhubarb compote evenly among the tart shells.

This can be done shortly before serving to keep the shell crisp.

Step 5: Garnish and Serve

Top each tart with whipped cream for a creamy contrast to the tangy compote.

For an extra touch, add a mint leaf as a garnish if desired.

Serve immediately and enjoy your delightful rhubarb tarts!
