Sassy Spinach Soup

This is what happens when spinach soup meets creamy mac and cheese, and the cross-pollination somehow works. Thin noodles break down just enough to thicken the broth, while a double hit of melted cheddar and Swiss cheese creates a silky, spoon-coating finish that beats any boxed soup on the shelf.

The cheddar-Swiss pairing is the smart move. Sharp cheddar brings tang and color; Swiss adds nutty, creamy depth and melts without the stringy pulls that mozzarella would produce. Using both gives the soup body and complexity neither would deliver alone.

Squeezing the frozen spinach dry before adding is the step home cooks skip at their peril. Wet spinach waters down the soup and kills the creamy consistency. A firm squeeze in a clean dish towel pulls out enough liquid to keep the finished bowl thick and luxurious.

Critically, the soup should never boil after the milk and cheese go in. High heat breaks the emulsion and leaves you with grainy, separated soup. Medium-high with constant stirring until the cheese melts smooth is the target.

Kitchen Tips

• Use fresh-grated cheese; pre-shredded has anti-caking starch that prevents smooth melting
• Keep the water at a steady boil when adding the noodle flakes so they cook evenly and do not clump
• Do not boil after cheese goes in, keep the heat at medium-high and stir constantly until smooth
• The soup thickens as it cools; add a splash of milk or broth when reheating leftovers

Variations

• Stir in a cup of shredded rotisserie chicken for more protein and a heartier meal
• Add a pinch of nutmeg with the milk; the classic cream soup aromatic brightens everything
• Top each bowl with crispy bacon bits, croutons, or a drizzle of hot sauce for texture and heat
