Frozen blueberry blintzes are a delightful make-ahead breakfast or dessert featuring delicate crepes filled with a sweet, tangy blueberry filling. They are perfect for busy mornings or impromptu brunches, as you can prepare a batch and freeze them for later. This recipe yields tender crepes with a luscious blueberry center, ready to be pan-fried to golden perfection straight from the freezer.
Ingredients
- For the Crepes:
- 1 cup (125 g) all-purpose flour
- 1 tablespoon (15 g) granulated sugar
- 1/4 teaspoon salt
- 3 large eggs
- 1 1/4 cups (300 ml) whole milk
- 2 tablespoons (30 g) unsalted butter, melted, plus more for the pan
- 1/2 teaspoon vanilla extract
- For the Blueberry Filling:
- 2 cups (300 g) fresh or frozen blueberries (if frozen, thaw and drain)
- 1/4 cup (50 g) granulated sugar
- 1 tablespoon (15 ml) lemon juice
- 1 teaspoon lemon zest
- 1 tablespoon (8 g) cornstarch mixed with 2 tablespoons (30 ml) cold water
- For Assembly and Cooking:
- 1 large egg, beaten (for sealing the blintzes)
- 2 tablespoons (30 g) unsalted butter, for frying
- Optional: powdered sugar, sour cream, or extra blueberries for serving
Instructions
- Make the crepe batter: In a blender, combine the flour, sugar, salt, eggs, milk, melted butter, and vanilla. Blend until smooth, about 30 seconds. Let the batter rest at room temperature for 15 minutes (this helps the crepes be more tender).
- Cook the crepes: Heat a non-stick skillet or crepe pan over medium heat. Lightly butter the pan. Pour about 1/4 cup (60 ml) of batter into the center, swirling to coat the bottom evenly. Cook for 1-2 minutes until the edges look set and the bottom is lightly golden. Flip and cook for another 30 seconds. Transfer to a plate. Repeat with the remaining batter, stacking the crepes with parchment paper between them. You should have about 8 crepes. Let them cool completely.
- Make the blueberry filling: In a medium saucepan, combine the blueberries, sugar, lemon juice, and lemon zest. Cook over medium heat, stirring occasionally, until the blueberries release their juices and the mixture comes to a simmer, about 5-7 minutes. If using fresh blueberries, you may need to add 1-2 tablespoons of water to prevent sticking.
- Thicken the filling: Stir the cornstarch slurry again, then pour it into the blueberry mixture. Cook, stirring constantly, until the mixture thickens and becomes glossy, about 2 minutes. Remove from heat and let cool completely. The filling will thicken further as it cools.
- Assemble the blintzes: Place a crepe on a clean work surface with the lighter side up. Spoon about 2 tablespoons of the cooled blueberry filling onto the center of the crepe. Fold the bottom edge over the filling, then fold in the sides, and roll up tightly like a burrito. Brush the top edge with the beaten egg to seal. Repeat with the remaining crepes and filling.
- Freeze the blintzes: Place the assembled blintzes on a baking sheet lined with parchment paper, making sure they are not touching. Freeze for at least 1 hour, or until firm. Once frozen, transfer them to a freezer-safe bag or container, separating layers with parchment paper. They can be stored for up to 3 months.
- Cook from frozen: When ready to serve, heat 1 tablespoon of butter in a large skillet over medium heat. Add the frozen blintzes in a single layer (do not overcrowd). Cook for 3-4 minutes per side, until golden brown and heated through. The internal temperature should reach 165°F (74°C) as a safe minimum for leftovers, though these are fully cooked and just need reheating. Serve immediately.
Tips
- Crepe batter rest: Don’t skip the 15-minute rest for the batter. This allows the gluten to relax, resulting in more tender crepes that are less likely to tear when folding.
- Filling consistency: Make sure the filling is completely cooled before assembling. If it’s warm, it will make the crepes soggy and harder to seal.
- Sealing the blintzes: The beaten egg acts as a glue to seal the edges. If you skip this, the blintzes may open during frying. You can also use a little water, but egg is more reliable.
- Freezing in batches: Freeze the blintzes in a single layer first. If you stack them before they’re firm, they’ll stick together and be impossible to separate without tearing.
Serving Suggestions
Serve the blintzes warm, dusted with powdered sugar and a dollop of sour cream or Greek yogurt. A drizzle of maple syrup or a spoonful of additional fresh blueberries on top also works beautifully. For a brunch spread, pair them with scrambled eggs and bacon.
Variations
- Cheese filling: For a classic blintz, replace the blueberry filling with a mixture of 2 cups (450 g) ricotta cheese, 1 egg yolk, 2 tablespoons sugar, and 1/2 teaspoon vanilla extract. Cook as directed.
- Mixed berry: Substitute half of the blueberries with raspberries or blackberries for a different flavor profile.
- Lemon curd: For a tangier option, use 1 cup (240 ml) of lemon curd as the filling. Omit the lemon zest in the blueberry version if you do this.
- Gluten-free: Use a 1:1 gluten-free flour blend instead of all-purpose flour. The crepes may be slightly more delicate, so handle them gently.
Storage and Reheating
Refrigerator: Cooked blintzes can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet over medium heat for 2-3 minutes per side, or in the microwave for 1-2 minutes.
Freezer: Uncooked, assembled blintzes can be frozen for up to 3 months as described in the instructions. Cooked blintzes can also be frozen; place them on a baking sheet to freeze individually, then transfer to a bag. Reheat frozen cooked blintzes in a 350°F (175°C) oven for 10-12 minutes, or until heated through.
Frequently Asked Questions
Can I use frozen blueberries directly in the filling without thawing? Yes, you can. If using frozen berries, add them directly to the saucepan and increase the cooking time by 2-3 minutes. Just make sure the mixture comes to a full simmer before adding the cornstarch.
Why are my crepes tearing? Crepes can tear if the batter is too thin or if the pan is too hot. Make sure the batter has rested, and use a medium heat. Also, be gentle when flipping; use a thin spatula.
Can I make the crepes ahead of time? Absolutely. You can cook the crepes up to 2 days in advance and store them in the refrigerator, wrapped in plastic wrap. Let them come to room temperature before assembling.
How do I know when the blintzes are done cooking? They should be golden brown on both sides and heated through. Since the filling is already cooked, you’re mainly reheating. If you’re unsure, check the center with a food thermometer—it should read at least 165°F (74°C).
Can I bake the blintzes instead of frying? Yes, you can bake them. Preheat your oven to 375°F (190°C), place the blintzes on a baking sheet, brush with melted butter, and bake for 12-15 minutes, flipping halfway, until golden and heated through.
What if my filling is too runny? If the filling is too runny after cooking, you can add a little more cornstarch slurry (1 teaspoon cornstarch mixed with 1 tablespoon water) and cook for another minute. Also, ensure the filling is completely cool before assembling; a warm filling will loosen the crepes.
