Common Questions
Why did my broccoli cheese soup turn grainy?
Usually it is heat. Cheese does not love boiling. Keep the soup at a gentle simmer, turn the heat to low, then add the cheese in handfuls while stirring. Also, use freshly shredded cheddar if you can. Pre-shredded cheese often has anti-caking agents that can mess with meltiness.
Can I make this without heavy cream?
Yes. The soup is already plenty creamy from the roux and milk. You can skip the cream entirely, or swap it for more whole milk. Evaporated milk also works if you want extra body without adding cream.
Can I use frozen broccoli?
Absolutely. Add it straight from frozen, but expect it to cook faster and soften more. If you like more texture, stir it in near the end and keep the simmer gentle.
How do I make it thicker?
This version is already spoon-clingy, but you have options. Let it simmer a few extra minutes to reduce, or mash some of the broccoli and carrots against the side of the pot. If you want it extra thick, whisk 1 tablespoon flour into 2 tablespoons softened butter to make a quick paste, then stir it in and simmer 3 to 4 minutes before adding the cheese.
How do I make it gluten-free?
Skip the flour roux and thicken with a cornstarch slurry instead: whisk 3 tablespoons cornstarch with 3 tablespoons cold milk, then stir into the simmering soup and cook 2 minutes before adding cheese. (If you like it very thick, use 4 tablespoons.)
