Classic's note

Take the pot off the heat before the cheese goes in. Boiled cheese splits into grease and rubbery strands, and it cannot be brought back.

Method

6 steps · tap one to tick it off

Tips

  • Grate the cheddar from a block. Pre-shredded cheddar is coated in starch to stop it clumping, which makes the soup grainy and adds carbs. Grate it yourself and add it off the heat.

  • Vent the blender lid. Hot soup expands when blended and can force a sealed lid off. Fill the jug halfway and leave the center cap open under a towel, or use a stick blender.

  • Season only after the cheese melts. Cheddar and broth are both salty. Taste once the cheese is in, or the soup ends up oversalted.

Swaps

  • No vegetable broth? Water with a vegetable bouillon cube. Choose a low-sodium one, since the cheddar is salty.

  • No cream? Full-fat cream cheese, whisked in until smooth before the cheddar. Thicker and tangier.

  • No mustard powder? Dijon mustard, stirred in with the cream instead.

Storage

  • Fridge: 3 to 4 days in a sealed container.

  • Freezer: Not worth freezing: the cream and cheddar split and turn grainy on thawing. Freeze the blended base before they go in, for 2 to 3 months.

  • Reheat: Over low heat, stirring often and never letting it boil, until steaming hot (75°C in the center).

Fridge and reheating follow Illinois Extension; freezer times are for quality and follow the University of Nebraska-Lincoln, as on what freezes and what does not.
