Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F and place six 6-oz ramekins in a deep roasting pan.
  2. Step 2: In a small saucepan over medium heat, combine 1/2 cup granulated sugar and 1/4 cup water; cook without stirring until the mixture turns a deep amber caramel color, about 8-10 minutes. Immediately pour the caramel evenly into the bottoms of the ramekins, swirling to coat.
  3. Step 3: In a large bowl, whisk together 4 whole eggs, 2 egg yolks, 1/2 cup granulated sugar, 2 cups whole milk, 1 can (14 oz) sweetened condensed milk, and 2 tsp vanilla extract until smooth.
  4. Step 4: Strain the custard through a fine mesh sieve to remove any lumps, then carefully pour the mixture over the caramel in each ramekin.
  5. Step 5: Pour hot water into the roasting pan until it reaches halfway up the sides of the ramekins to create a water bath.
  6. Step 6: Bake for 50-60 minutes until the custard is just set but still slightly jiggly in the center.
  7. Step 7: Remove ramekins from water bath and cool to room temperature; refrigerate at least 4 hours or overnight.
  8. Step 8: To serve, run a thin knife around the edges and invert each flan onto a dessert plate, allowing the caramel sauce to drizzle over.

Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.

Can I substitute ingredients in San Antonio-Inspired Mexican Vanilla Flan?

How do I scale San Antonio-Inspired Mexican Vanilla Flan for a different number of people?

The recipe is written for 6 servings. Multiply each ingredient by (your serving target / 6). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
