Common Questions
Can I use frozen broccoli?
Yes. Frozen broccoli works great for weeknights. Add it straight in and simmer until tender. It will cool the soup for a minute and may need a slightly longer simmer depending on floret size. Expect it to break down a bit more, which is totally fine in a creamy soup.
Why did my cheese turn grainy?
Usually it is heat. Add the cheese off the heat and stir until melted. Also, use freshly shredded cheddar if possible. Pre-shredded cheese has anti-caking agents that can affect melt.
Do I have to blend the soup?
Nope. Blending just a portion makes it feel thicker and more velvety. If you use an immersion blender, do it in short bursts, about 3 to 10 seconds total, so you do not overdo it and dull the broccoli. You can also mash with a potato masher for a low-drama option, or skip entirely for a more brothy texture.
Can I make it gluten-free?
Yes. Swap the all-purpose flour for a gluten-free 1:1 flour blend. Results can vary by brand, so choose one labeled for sauces or thickening. For a more predictable option, skip the flour and thicken at a simmer with a cornstarch slurry: whisk 2 tablespoons cornstarch with 2 tablespoons cold water, then stir it in and simmer 1 to 2 minutes until the soup thickens.
What cheddar should I use?
Sharp cheddar gives the most flavor. Mild cheddar melts nicely but can taste a little flat. My sweet spot is sharp cheddar plus a small handful of white cheddar if you want it extra cozy. For the smoothest melt, shred from a block.
