Method
Prep
- Shred the white cheddar and keep it chilled; core and dice the apples and finely chop the onion.
Cook aromatics
- Melt butter in a 4- to 6-quart Dutch oven over medium heat, add the chopped onion and a pinch of salt, and cook until translucent, 6–8 minutes. Add the minced garlic and cook 30 seconds.
Make the base
- Stir in the flour and cook 1–2 minutes to remove the raw flavor, then slowly whisk in the milk and broth, scraping the bottom. Add the diced apples, salt, pepper, and thyme and bring to a gentle simmer.
- Simmer until apples are tender, 8–10 minutes, then remove the pot from the heat.
Finish and temper
- Use an immersion blender to puree the soup mostly smooth (or puree half in a blender and return). Let the soup sit off heat 1 minute, then add the shredded cheddar in four additions, stirring until each addition melts before adding more. If too thick, stir in up to 1/4 cup additional milk.
- Return to the lowest heat and warm gently 2–3 minutes; do not boil. Stir in heavy cream and lemon juice if using. Adjust seasoning.
Serve
- Ladle into bowls and top with toasted pecans and chives if desired. Serve with crusty bread.
Notes
Shred cheese from a block for best melting—pre-shredded cheese can be waxy. If using cornstarch for gluten-free thickening, mix 2 tablespoons cornstarch with 2 tablespoons cold milk and stir into simmering soup instead of flour. Do not boil the soup after adding cheese; heat gently to avoid separation.
