Add broth: Pour in the vegetable or chicken broth. Bring the mixture to a simmer and let it cook for about 15 minutes until the broccoli is tender.
Thicken the soup: In a small bowl, mix the flour with a bit of the cream to create a slurry. Gradually whisk in the remaining cream and add to the pot. Stir well.
Stir in cheese: Reduce the heat to low and sprinkle the shredded cheddar cheese into the soup, stirring until melted and creamy.
Season the soup: Add salt, pepper, and nutmeg to taste. Adjust seasoning as necessary.
Serve warm: Once everything is well combined and heated through, remove from the heat and prepare to serve.
Notes
Pairs well with crusty sourdough bread or a simple green salad. Freezes well for up to 2 months.
