How to make Broccoli Cheese Soup:
You’ll start with a classic soup base of onion and garlic; which is pretty much the best way to start any dish in my personal opinion! Then you’ll melt the butter and add flour.
You’ll stir the flour into the veggies and cook it for about 1 minute. Then you’ll add vegetable broth.
Next add milk and a few spices. Then stir in shredded cheese until it is all melted and creamy.
And last but not least of course, add the broccoli!
Simmer everything for 20 minutes, stirring occasionally and dinner is done!
What makes this broccoli cheddar soup so thick and creamy?
The combination of butter and flour in this recipe is what makes it so thick and creamy! Melted butter mixed with flour is called a roux. This is the base that is used to thicken numerous different kinds of soups and sauces in cooking.
Some recipes require you to remove the veggies and then create the roux with melted butter and flour. But after testing this recipe both ways, I found that it made no difference if I made the roux with the veggies right in the pot or separately.
And I’m all about short cuts, so save yourself some time and just melt the butter along with the onion and garlic and then stir in the flour!
Can you make broccoli cheese soup ahead of time?
Yes, just be aware that if you are going to make this soup ahead of time, you will likely need to add a couple splashes of milk when it comes time to re-heat!
Because of the roux and the cheese, this soup thickens up considerably as it cools. If you’re planning to reheat it at a later date, just make sure you add a few splashes of milk before reheating and probably a few more as it heats up!
Whenever I loosen up a soup with milk or another liquid, I always compensate for the dilution of flavor by adding a few big pinches of salt and a little more pepper.
Along the same lines, whenever you’re reheating any leftovers, it’s a great idea to season to taste with salt and pepper as the flavors do change over time.
Can you freeze broccoli cheese soup?
Yes! This soup freezes fabulously! I like to thaw it in the fridge overnight the day before I plan to reheat it. Once the soup is thawed, it will be easier to re-heat evenly.
As mentioned above, in regards to reheating you’ll definitely have to stir in some additional milk to loosen up the thickened soup if you’ll be enjoying it at a later date.
And don’t forget to give it another quick taste before serving and season with more salt and pepper!
Tips for making the best broccoli soup:
- Always use unsalted butter for this broccoli cheese soup. Using unsalted butter allows you to better control the amount of salt and therefor the flavor of the soup. In fact, you should use unsalted butter in every recipe, unless otherwise noted.
- Buy blocks of cheese and shred it yourself. Pre-shredded cheeses are coated with cellulose to help the shreds not stick together. Which also means that it won’t melt as well. I’ve often found that buying cheese in blocks is cheaper than pre-shredded too!
- Be sure to stir the soup occasionally as it simmers so that it doesn’t stick to the bottom and burn. Stirring every 5 minutes is perfect!
- When reheating this soup, make sure you add a bit more milk. As the soup cools it will thicken considerably. Adding milk will loosen it up and make it smooth and creamy again. Be sure to season taste with salt and pepper after reheating also!
