Blueberry Cobbler Recipe

Overview

This blueberry cobbler has a juicy, lightly thickened blueberry filling beneath a tender biscuit topping. Lemon zest and juice brighten the berries without overpowering their flavor, while a little cinnamon adds warmth.

Fresh or frozen blueberries both work well. Frozen berries can go straight into the baking dish, although the cobbler may need a few extra minutes in the oven. Serve it warm, when the fruit is glossy and bubbling and the topping is golden at the edges.

Ingredients

• 6 cups blueberries, fresh or frozen
• 1/2 cup granulated sugar, divided
• 2 tablespoons cornstarch
• 1 tablespoon lemon juice
• 1 teaspoon finely grated lemon zest
• 1 teaspoon vanilla extract
• 1/4 teaspoon ground cinnamon
• 1 1/2 cups all-purpose flour
• 2 teaspoons baking powder
• 1/2 teaspoon fine salt
• 6 tablespoons cold unsalted butter, cut into 1/2-inch cubes
• 1/2 cup whole milk, plus 1 tablespoon for brushing
• 1 large egg
• 1 tablespoon coarse sugar, optional, for sprinkling

How to make it

1. Heat the oven and prepare the dish. Set a rack in the center of the oven and heat it to 375°F (190°C). Lightly grease a 9-by-13-inch baking dish. Place the dish on a rimmed baking sheet to catch any juices that bubble over.

2. Make the blueberry filling. Add the blueberries, 1/4 cup of the granulated sugar, cornstarch, lemon juice, lemon zest, vanilla, and cinnamon to the baking dish. Stir gently until the berries are evenly coated. If using frozen blueberries, do not thaw them first.

3. Mix the dry ingredients. In a medium bowl, whisk together the flour, baking powder, salt, and the remaining 1/4 cup granulated sugar. Breaking up any small lumps now will help the topping bake evenly.

4. Cut in the butter. Add the cold butter and rub it into the flour mixture with your fingertips, or cut it in with a pastry blender. Stop when the mixture resembles coarse crumbs with a few pea-sized pieces of butter still visible. Those pieces help create a tender texture.

5. Add the wet ingredients. Whisk the egg and 1/2 cup milk in a small bowl. Pour this mixture into the flour mixture and stir with a fork or flexible spatula just until no dry flour remains. The dough should be thick and slightly sticky; do not keep mixing once it comes together.

6. Top the berries. Drop the dough over the blueberries in 10 to 12 rough mounds, leaving a few small gaps for steam to escape. The mounds do not need to be perfectly even. Brush the tops with the remaining 1 tablespoon milk and sprinkle with coarse sugar, if using.

7. Bake the cobbler. Bake for 45 to 55 minutes, or until the biscuit topping is deeply golden and the blueberry juices are bubbling visibly in the center, not just around the edges. If using frozen berries, expect the longer end of the baking time. If the topping browns before the filling bubbles, loosely cover the dish with foil and continue baking.

8. Cool before serving. Let the cobbler stand for at least 20 minutes. The fruit will thicken as it cools, making it easier to spoon. Serve warm on its own or with vanilla ice cream or lightly sweetened whipped cream.

Expert tips

• Use frozen berries without thawing. Thawed berries release extra liquid before baking and can make the filling looser. Add frozen berries directly to the dish and allow a little extra baking time.
• Keep the butter cold. Soft or melted butter can make the topping dense rather than tender. If the dough becomes warm while mixing, refrigerate it for 10 minutes before topping the fruit.
• Do not judge doneness by the edges alone. The middle of the filling must be actively bubbling so the cornstarch thickens properly. A pale topping or quiet center usually means the cobbler needs more time.
• For a less sweet cobbler, reduce the sugar in the filling to 3 tablespoons. Keep the sugar in the topping unchanged so it still browns properly.
• For a dairy-free version, use a plant-based butter that is suitable for baking and unsweetened, unflavored plant milk. The dough may be slightly less rich but should still be thick and spoonable.
• If the topping is dry, it was likely overmixed or the flour was packed into the measuring cup. Next time, spoon flour into the cup and level it, and stop stirring as soon as the dough comes together.
• If the filling is too runny, the cobbler may not have baked until the center bubbled, or it may have been served immediately. Let it cool for 30 minutes; if it is still loose, refrigerate leftovers before serving again.

Serving and storage

Serve the cobbler warm after its 20-minute rest. A scoop of vanilla ice cream contrasts with the warm fruit and tender topping, while plain yogurt gives a less sweet finish.

Cover cooled leftovers and refrigerate them within 2 hours of baking. They keep for up to 4 days in the refrigerator. Reheat individual portions in the microwave in short intervals, or warm the covered baking dish in a 325°F (165°C) oven until heated through. The topping is best on the first day, but reheating in the oven helps it regain some of its texture.

Frequently asked questions

Can I use frozen blueberries for this cobbler?

Yes. Add the frozen blueberries directly to the baking dish without thawing them. The filling may need 5 to 10 extra minutes in the oven, and it is done when the juices bubble in the center and the biscuit topping is golden.

Why is my blueberry cobbler runny?

The cobbler may have been removed before the center of the filling bubbled, or it may not have rested long enough. Cornstarch thickens as the filling heats, and the juices continue to set during a 20- to 30-minute cooling period.

Can I make blueberry cobbler with other berries?

Yes. Replace up to half of the blueberries with raspberries or blackberries. Juicier berries may produce a softer filling, so rely on the bubbling-center doneness cue and allow the cobbler to cool before serving.

How do I store leftover blueberry cobbler?

Cover the cooled cobbler and refrigerate it within 2 hours. It keeps for up to 4 days. Reheat portions in the microwave or warm the covered dish in a 325°F oven until hot.

Can I make the biscuit topping without an egg?

Yes. Replace the egg with 3 tablespoons of additional milk, adding it gradually until the dough is thick and spoonable. The topping may be slightly less rich and less deeply golden.
