Slow Cooker Vanilla and Orange Blossom Flan Step-by-step instructions

Before you start

Before beginning, ensure your slow cooker insert is clean and dry. Gather all ingredients and measure them accurately. If your slow cooker has a non-stick coating, avoid using metal utensils, as these can damage the surface and affect the cooking process.

Prepare a space in your refrigerator where the insert can sit level while it cools, ensuring there is enough clearance to allow for proper airflow around the container during the final chilling phase.

Instructions

Preparation and Mixing

1. 1Combine Ingredients
   Crack the four eggs directly into the base of the slow cooker insert. Add the granulated sugar, cornstarch, and whole milk into the insert. Use a whisk to combine all ingredients thoroughly until the cornstarch is completely dissolved and no lumps remain in the mixture.
   Look for mixture is smooth and uniform
   Tip Ensure the cornstarch is fully incorporated to prevent any powdery pockets during the cooking process.

At the end of this phase, the mixture should be completely homogeneous, with no visible streaks of egg whites or clumps of cornstarch. The sugar should be fully dissolved, and the texture should be thin and pourable. Check the bottom of the slow cooker insert to ensure all dry ingredients have been incorporated into the liquid, leaving a clean surface for the custard to set evenly during the cooking phase.

Slow Cooking

2. 2Slow Cook the Custard
   Cover the slow cooker with its lid. Set the appliance to the low heat setting and cook for approximately 3 hours. This gentle heat ensures the custard sets properly without curdling or developing air bubbles, maintaining the desired glossy and firm consistency throughout the entire dish.
   Look for center is set and slightly jiggly
   Safe temperature 160°F (71°C) internal temperature (egg dishes)
   Tip Avoid lifting the lid frequently, as this releases heat and moisture, which can alter the cooking time significantly.

After the cooking time, the custard will have transitioned from a thin liquid to a firm, set state. The surface should look smooth and glossy, not dry or cracked. It should feel firm to the touch when pressed lightly with a finger. The temperature should be at least 160°F (71°C). If the center still appears liquid, continue cooking for an additional 15 minutes before checking again, as individual slow cooker temperatures can vary.

Cooling and Setting

3. 3Cool and Set
   Once cooked, turn off the slow cooker and carefully remove the insert. Allow the flan to cool at room temperature for 30 minutes. Transfer the insert to the refrigerator to chill for at least 30 minutes, allowing the custard to firm up before slicing and serving on a chilled plate.
   Look for firm and cool to the touch
   Tip The cooling phase is essential for achieving the perfect sliceable texture that holds its shape on the plate.

Once the flan has cooled and spent time in the refrigerator, it should feel cool to the touch and appear very stable. It should release easily from the sides of the insert.

When sliced, the custard should hold its shape perfectly on the plate without sagging or losing its structure. The texture should be consistent throughout, offering a smooth, creamy sensation that is the hallmark of a properly prepared and cooled custard dessert.

Common mistakes

A common mistake is whisking the mixture too vigorously, which incorporates excess air and creates bubbles that mar the surface of the finished flan. Whisk just until the ingredients are combined. Another error is failing to allow the flan to cool completely.

Cutting into the flan while it is still warm will cause it to collapse, as the protein structure needs time to stabilize during the refrigeration process. Finally, do not rush the cooling time, as this is vital for texture.

How to tell it’s done

The flan is properly cooked when the edges are set and firm, while the center retains a slight, uniform jiggle when the insert is gently shaken. Using a digital thermometer, ensure the internal temperature reaches at least 160°F (71°C) to guarantee the eggs are safely cooked through.

The surface should appear glossy and smooth, with no signs of separation or liquid pooling. Once reached, remove from the heat immediately to prevent overcooking and potential graininess.
