Ingredients
  

Soup Ingredients
  • 1/4 cup Unsalted Butter 56g
  • 1 medium Yellow Onion 150g, finely diced
  • 3 cloves Fresh Garlic 15g, minced
  • 1/4 cup All-Purpose Flour 30g
  • 3 cups Chicken or Vegetable Broth 720ml
  • 2 cups Whole Milk or Heavy Cream 480ml
  • 3 medium Yukon Gold Potatoes 600g, peeled and diced into 1/2-inch cubes
  • 3 cups Fresh Broccoli Florets 250g, chopped into bite-sized pieces
  • 2.5 cups Sharp Cheddar Cheese 280g, freshly shredded from a block
  • 1 tsp Kosher Salt 5g
  • 0.5 tsp Freshly Ground Black Pepper 1g, plus extra for garnish

Equipment

  • 1 Heavy-bottomed Dutch Oven Essential for even heat distribution to prevent the dairy from scorching.
  • 1 Wooden Spoon or Silicone Whisk Necessary for creating a lump-free roux.

Method
 

Soup Preparation
  1. Place your Dutch oven over medium heat and melt the butter until it begins to foam. Add the finely diced yellow onion and sauté for 4-5 minutes. Stir in the minced garlic and cook for 30 seconds more.
  2. Sprinkle the all-purpose flour evenly over the butter and onion mixture. Whisk continuously for 1 to 2 minutes until the flour turns a light golden color.
  3. Slowly pour in the broth, whisking vigorously. Gradually stream in the whole milk. Add the diced Yukon gold potatoes, salt, and half the black pepper. Bring to a gentle boil, reduce heat to low, cover, and simmer for 15 minutes.
  4. Once potatoes are tender, stir in the fresh broccoli florets. Keep the pot uncovered and simmer for an additional 5-7 minutes until the broccoli is tender-crisp and vibrant green.
  5. Remove the pot entirely from the heat. Gradually sprinkle in the freshly shredded sharp cheddar cheese, stirring gently until completely melted and smooth. Serve hot garnished with black pepper.

Notes

Always grate your own cheese from a block; pre-shredded cheese contains anti-caking agents that will cause a gritty soup texture.
Never boil the soup after adding the cheddar cheese, or the dairy will separate and become oily.
