for white sauce :

  • 2 tsp butter
  • 1 tbsp all-purpose flour (maida)
  • 2 tbsp onion finely chopped
  • 2 tbsp capsicum finely chopped
  • 2 tbsp carrot peeled & grated
  • 2 tbsp boiled sweet corn
  • 1 cup milk
  • ¼ tsp black pepper powder
  • ½ tsp oregano
  • ½ tsp chilli flakes
  • Salt as required
  • 1 cheese cube
  • 4 slices white bread
  • Butter as required for toasting bread


preparing white sauce for sandwich :

  • Collect all the required ingredients.
  • Heat 1 tsp butter in a thick bottomed pan on low flame.
  • Add chopped onion.
  • Saute for a minute or two on low flame.
  • Then add chopped capsicum, grated carrot, and boiled corn.
  • Stir and saute until veggies are little cooked but still crunchy, for around 2-3 minutes on low-medium flame.
  • Now add the remaining butter.
  • When butter melts, add maida.
  • Stir the flour quickly as soon as you add it. Keep on stirring so that no lumps are formed.
  • Saute for a few seconds. Make sure the color of the flour doesn’t change.
  • Keep the flame to the lowest and then pour 1 cup milk in a gentle stream.
  • Pour the milk with one hand and stir the sauce mixture with the other while stirring continuously.
  • Now add salt and black pepper powder.
  • Add cheese if using. I used processed cheese cube here, you can also use grated cheddar cheese also.
  • Then add oregano and chilli flakes.
  • Mix it well and keep stirring until the mixture becomes slight thick and creamy. Cook in low flame.
  • Gently stir until the mixture reaches a thick sauce consistency and the cheese blends well.
  • When the mixture starts to coat the back of a spoon as shown in the picture here, it means that it has started to thicken.
  • Once the sauce is thick in spreadable consistency, give a quick mix and switch off the flame. Set aside to cool.

making white sauce sandwich :

  • Add butter to a hot pan and place the bread slices. You can also smear the softened butter over the slices.
  • Toast bread until golden on one side of both the slices.
  • Flip both of them and transfer them to a plate.
  • Toast the remaining bread slices also.
  • Apply the prepared white sauce over the toasted bread.
  • Spread the sauce evenly on the bread.
  • Cover the white sauce topped bread with the other toasted bread. Place the golden side over the sauce.
  • Smear softened butter on top of the bread slices.
  • Place the white sauce sandwich carefully with the buttered side facing down.
  • Press down on the sandwich with the back of a flat spatula to press the sandwich together.
  • When the bottom bread is grilled well, then spread some butter on top side which is facing you.
  • With a spatula turn over the sandwich. You will see the crisp and grilled side facing you.
  • Flip a couple of times till the white sauce sandwich is crisp and golden.
  • Cut the bread into the half or into desired size and shape.
  • Serve hot.


  • Oregano and pepper powder gives a great flavour.
  • This white sauce mixture will keep well for 3 days if kept in the refrigerator. 
  • I skipped green chillies and added pepper powder instead.
  • Adjust the spiciness as required. 
  • Make sure the sauce is thick enough to apply on bread. 
  • You can also apply tomato ketchup on side of bread. 
  • You can make vegetable white sauce sandwich by adding more vegetables like cabbage, peas, and broccoli. 
  • You can also make open sandwich by just applying the prepared mixture on one side of bread and cook on pan by covering the lid of pan. 
  • I used white bread, you can use wheat or multigrain bread too.
  • I cut each them into small traingles to make serving for kids easier and they will love it too.
  • Make sure you cool down white sauce before you apply it.
  • The white sauce thickens with time so switch it off accordingly.
  • After applying the white sauce, serve immediately else the sandwich will become soggy if resting time is given.
