Irresistible Strawberry Rhubarb Grunt

Here is my favorite strawberry rhubarb grunt recipe, with a simple biscuit topping that steams right on top of the fruit, and a filling made with fresh strawberries, tart rhubarb, sugar, lemon juice, and vanilla.

This grunt is the dessert I turn to every spring when rhubarb season hits. I love that you don’t need to turn on the oven – everything cooks in one pot on the stovetop. Plus, it’s ready in about 30 minutes, which is perfect for those nights when you want something sweet but don’t want to spend hours in the kitchen.

What Kind of Rhubarb Should I Use?

Fresh rhubarb is always your best bet for this recipe, and you’ll find it in season during spring and early summer at most grocery stores and farmers markets. The color of the stalks – whether they’re bright red, pink, or greenish – doesn’t actually affect the flavor much, so don’t worry if yours looks different than what you see in pictures. Just make sure to trim off and discard the leaves completely, as they’re toxic, and cut off any dried or damaged ends before chopping. If fresh rhubarb isn’t available, you can use frozen rhubarb instead – just don’t thaw it before adding it to the recipe, as this will help prevent it from getting too mushy.

Options for Substitutions

This classic dessert is pretty forgiving when it comes to swaps:

• Rhubarb: If rhubarb isn’t in season or you can’t find it, you can use all strawberries instead (7 cups total). You might want to add an extra tablespoon of lemon juice to keep that tart balance.
• Strawberries: Fresh is best, but frozen strawberries work too. Just thaw them first and drain any excess liquid before using. You can also try raspberries or blackberries for a different berry twist.
• Butter: Shortening works great if you prefer it, or you can use half butter and half shortening. Some folks even use coconut oil for a dairy-free option – just make sure it’s cold and solid.
• Milk: Any milk works here – whole, 2%, or even buttermilk. For dairy-free, try oat milk or almond milk. Start with 3/4 cup and add more as needed to get a thick, biscuit-like dough.
• All-purpose flour: You can use a 1:1 gluten-free flour blend if needed, though the dumplings might be slightly less fluffy.

Watch Out for These Mistakes While Cooking

The biggest mistake when making grunt is lifting the lid while the dumplings cook, which releases the steam they need to cook through properly – resist the urge to peek for the full 15 minutes.

Another common error is making the dough too thick or too thin, so aim for a consistency that’s sticky but still holds its shape when scooped, adding milk gradually until you get it just right.

If your fruit mixture isn’t simmering gently when you add the dumplings, they’ll either sink to the bottom or cook unevenly, so make sure you see steady bubbles before dropping the dough on top.

To test if the dumplings are done, insert a toothpick into the center – it should come out clean, and if it doesn’t, cover and give them another 3-5 minutes.

What to Serve With Strawberry Rhubarb Grunt?

This warm, fruity dessert is absolutely perfect with a big scoop of vanilla ice cream melting into all those strawberry-rhubarb juices. I love serving it straight from the pot while it’s still warm, letting everyone dig in family-style with their own bowls and spoons. A dollop of fresh whipped cream or even some tangy Greek yogurt works great too, especially if you want to balance out the sweetness. For a fun breakfast twist, leftover grunt is amazing the next morning with a drizzle of maple syrup and a cup of strong coffee.

Storage Instructions

Store: Keep your strawberry rhubarb grunt covered in the fridge for up to 3 days. The dumplings will soften a bit as they sit, but the flavors actually get better as everything melds together overnight.

Freeze: You can freeze the fruit filling on its own for up to 3 months, but I don’t recommend freezing the whole dish with the dumplings. They tend to get a bit mushy when thawed, so it’s better to make fresh dumplings when you’re ready to serve.

Reheat: Warm up individual portions in the microwave for about 30-60 seconds, or reheat the whole dish covered in a 300°F oven for about 15-20 minutes. It won’t be quite as fluffy as fresh, but it’s still delicious served warm with a scoop of vanilla ice cream.

• Fat: 22-26 g
• Carbohydrates: 370-410 g

Ingredients

For the fruit base:

• 3.5 cups strawberries (hulled and sliced into 1/2-inch thick pieces)
• 3.5 cups rhubarb (trimmed and cut into 1/2-inch slices)
• 1.25 cups sugar
• 4 tsp lemon juice (freshly squeezed for best acidity balance)
• 3/4 cup water
• 1 tsp vanilla extract

For the dough:

• 2 cups flour (I always use King Arthur all-purpose flour)
• 1 tbsp baking powder
• 1/2 tsp salt
• 1/4 cup sugar
• 1/2 tsp ground cinnamon
• 6 tbsp butter (I like Kerrygold unsalted butter for this)
• 3/4 cup milk (room temperature, about 70°F)

Step 1: Prepare the Mise en Place and Make the Biscuit Dough

• 2 cups flour
• 1 tbsp baking powder
• 1/2 tsp salt
• 1/4 cup sugar
• 1/2 tsp ground cinnamon
• 6 tbsp butter
• 3/4 cup milk
• 3.5 cups strawberries
• 3.5 cups rhubarb
• 4 tsp lemon juice

While you’re preparing ingredients, get a head start on the biscuit dough since it needs minimal mixing.

In a medium bowl, whisk together the flour, baking powder, salt, sugar, and cinnamon.

Cut the cold butter into small cubes and add to the dry mixture.

Using your fingertips or a pastry cutter, work the butter into the flour until the mixture resembles coarse breadcrumbs with some pea-sized pieces of butter remaining—this creates the flaky texture in the finished dumplings.

Stir in the milk until just combined into a shaggy, sticky dough; don’t overmix or the biscuits will be tough.

Set the dough aside.

Meanwhile, hull and slice the strawberries into 1/2-inch thick pieces, trim the rhubarb and cut it into 1/2-inch slices, and squeeze fresh lemon juice into a small bowl.

Step 2: Build the Fruit Base and Bring to a Simmer

• 3.5 cups strawberries
• 3.5 cups rhubarb
• 1.25 cups sugar
• 4 tsp lemon juice
• 3/4 cup water
• 1 tsp vanilla extract

Add the sliced strawberries and rhubarb to a large, heavy-bottomed pot or Dutch oven with the sugar, lemon juice, water, and vanilla extract.

Stir well to combine and dissolve the sugar slightly.

Place the pot over medium-high heat and bring the mixture to a gentle boil, stirring occasionally to help the fruit release its juices and ensure even cooking.

Once boiling, reduce the heat to medium-low and let it simmer for about 5 minutes.

I like to taste the fruit at this point—the acidity from the rhubarb should be balanced by the strawberry sweetness and lemon juice, creating a bright filling that won’t be too tart.

Step 3: Add the Biscuit Dumplings and Steam Until Cooked

• biscuit dough from Step 1
• fruit mixture from Step 2

Using a large spoon or ice cream scoop, drop spoonfuls of the biscuit dough from Step 1 directly onto the simmering fruit mixture, spacing them about an inch apart—they’ll expand slightly as they cook.

Cover the pot with a lid (or use foil if you don’t have one that fits) and reduce the heat to medium-low to maintain a gentle simmer.

Let the grunts cook for about 15 minutes without lifting the lid, as the steam is essential for cooking the dumplings through.

I find that keeping the heat steady and consistent prevents the bottom from scorching while the tops stay moist and tender.

Step 4: Check Doneness and Serve

After 15 minutes, carefully remove the lid and check if the biscuits are cooked through by inserting a toothpick into one of the larger dumplings—it should come out clean or with just a few moist crumbs, not wet batter.

If the toothpicks shows wet batter, cover and simmer for another 2-3 minutes.

The fruit should be bubbling gently around the edges, and the biscuits should be set and lightly golden on top.

Serve the strawberry rhubarb grunt warm in bowls, spooning both the biscuits and the berry sauce into each serving.

Step 5: Finish and Serve with Accompaniments

Divide the warm grunt between serving bowls, making sure each bowl has a generous portion of both biscuits and fruit sauce.

Top with softly whipped cream, vanilla ice cream, or a dollop of crème fraîche if desired.

The warmth of the grunt will soften ice cream beautifully while the cool creaminess balances the tart fruit.
