Whether you’re introducing your friends and family to kabocha for the first time or treating yourself to a new take on flan, this recipe will quickly become a household favorite.

Ingredients for Instant Pot Kabocha Flan

Flan Custard

• 3 large eggs (50 g each, without shells)
• ½ cup milk
• ½ cup heavy whipping cream
• 1 tsp pure vanilla extract
• 3 Tbsp sugar
• 15 oz kabocha squash (weighed with seeds)

Caramel Sauce

• 4 Tbsp sugar
• 1 Tbsp water
• 2 Tbsp hot water

Tools Needed

• Instant Pot (with steamer basket and trivet)
• 4 ramekins (6-oz each)
• Fine-mesh sieve or food processor

Preparing the Kabocha Squash

Start by choosing a fresh kabocha squash. Look for one with a firm exterior and vibrant green color. Rinse the kabocha under running water and cut it in half to remove the seeds using a spoon. Cut the squash into wedges and then into 2-inch pieces for steaming. The kabocha’s skin is edible but will not be used in this recipe to maintain the custard’s silky texture.

Add 1 cup of water to the Instant Pot and place the steamer basket inside. Arrange the kabocha pieces in a single layer and seal the lid. Set the Instant Pot to High Pressure for 2 minutes, ensuring the steam release handle is set to “Sealing.” Once done, allow the pressure to release naturally for 10 minutes before performing a quick release. The kabocha should now be tender enough to easily scoop out the flesh.

To create the kabocha purée, press the steamed flesh through a fine-mesh sieve or use a food processor for a smoother texture. Measure out ½ cup (120 g) of the purée and set it aside. If you have extra purée, save it for other recipes, such as soups or smoothies.

Crafting the Caramel Sauce

The caramel sauce is the heart of any flan, providing a rich and slightly bitter contrast to the sweet custard. In a small saucepan, combine 4 tablespoons of sugar with 1 tablespoon of water. Heat over medium heat without stirring, gently shaking the pan occasionally to distribute the sugar evenly. As the sugar melts and turns golden brown, watch closely to prevent burning. Once the caramel reaches a deep amber color, carefully add 2 tablespoons of hot water to loosen it. Be cautious, as the mixture will bubble vigorously. Swirl the pan to combine and immediately pour the caramel into the bottom of each ramekin. Allow the caramel to cool and harden before proceeding.

Mixing the Custard

In a large mixing bowl, whisk together the eggs and sugar until the mixture is well combined but not frothy. Add the milk, heavy cream, and vanilla extract, mixing gently to incorporate. Finally, stir in the prepared kabocha purée, ensuring the mixture is smooth and homogeneous. For an ultra-silky texture, strain the custard through a fine-mesh sieve into a large measuring cup or bowl. This step removes any lumps and ensures a creamy final product.

Divide the custard mixture evenly among the ramekins, pouring it over the cooled caramel. Cover each ramekin tightly with aluminum foil to prevent condensation from dripping into the custard during cooking.

Cooking the Flan in the Instant Pot

Add 1 cup of water to the Instant Pot and place the trivet inside. Arrange the ramekins on the trivet, ensuring they are stable and not tilted. Close the lid and set the Instant Pot to High Pressure for 6 minutes. Once the cooking cycle is complete, let the pressure release naturally for 10 minutes before performing a quick release. Carefully remove the ramekins from the Instant Pot using tongs or a kitchen towel.

To check for doneness, insert a skewer into the center of one flan. If it comes out clean or with just a slight wobble, the flan is set. If the custard appears undercooked, return the ramekins to the Instant Pot and cook for an additional 1–2 minutes.

Allow the flans to cool to room temperature before transferring them to the refrigerator. Cover the ramekins with a paper towel to absorb any condensation, then wrap them in plastic wrap. Chill for at least 2 hours, or preferably overnight, to fully set the custard and enhance the flavors.

Serving Suggestions

To serve, run a knife around the edge of each ramekin to loosen the flan. Place a serving plate over the ramekin, then invert and gently shake to release the flan onto the plate. The caramel sauce will cascade beautifully over the custard, creating an elegant presentation.

For a touch of flair, garnish with a dollop of whipped cream, a sprinkle of cinnamon, or a drizzle of additional caramel sauce. Pair the flan with a cup of green tea or a light dessert wine for a truly indulgent experience.

Tips and Variations

• Ingredient Substitutions:
  If you don’t have kabocha squash, substitute it with butternut squash or sweet potato for a similar texture and flavor. For a dairy-free version, use coconut milk and coconut cream in place of milk and heavy cream.
• Texture Adjustments:
  If you prefer a firmer flan, increase the cooking time by 1–2 minutes. For a softer, more delicate custard, reduce the cooking time slightly.
• Flavor Enhancements:
  Experiment with adding spices like cinnamon, nutmeg, or ginger to the custard mixture for a warm, spiced twist. A touch of orange zest can also brighten the flavors and add complexity.
• Presentation Ideas:
  For individual servings, use smaller ramekins or decorative molds. To serve a larger group, consider making the flan in a single baking dish and slicing it into portions.
• Storage Tips:
  Leftover flan can be stored in the refrigerator for up to 2 days. Keep the ramekins covered to prevent the custard from absorbing odors or drying out.
