Instructions
 

Oven Instructions (recommended method)

  • Place unwrapped soup brick in an oven safe dish large enough to contain the full portion (soup is 10 oz). Bake in 400 degree F oven for 40 minutes, until cheese is melted and golden brown.

Quick Oven Method

  • Place unwrapped soup cube in an oven and microwave safe bowl and microwave for 3 minutes on high. Transfer to 400 degree oven for approximately 20 minutes until cheese is melted.

Stove Top Instructions

  • Place unwrapped soup brick in a small saucepan. Heat on medium, moving the frozen block around occasionally with a spoon as it starts to melt. Stir more frequently and reduce heat to low as the liquid boils around the frozen puck. Takes 15-20 minutes.

Microwave Instructions

  • Place unwrapped soup cube in a microwave safe bowl and heat on high for 3 minutes. Stir and microwave an additional 2 minutes.

Notes

For all methods, place soup cheese side up to heat.
For air fryers, follow oven instructions but reduce cooking time- start checking at 25 minutes.
