Pro Tips from My Kitchen

I’ve learned a few crucial things while making this soup over the years:

  • Always grate your own cheese. Pre-shredded cheese contains anti-caking agents that can make your soup grainy
  • Room temperature dairy products are essential for preventing curdling
  • Don’t rush the cheese-melting process – low and slow is key
  • For extra flavor, roast the vegetables before adding them to the soup
  • Save some of the smaller broccoli florets to add as garnish

Common Questions and Answers

Q: Can I make this soup vegetarian?
A: Yes! Simply ensure you’re using vegetable stock and verify that your cheeses are made with vegetarian rennet.

Q: How can I make this soup lower in calories?
A: You can substitute half-and-half for the heavy cream and use light cream cheese. While it won’t be quite as rich, it will still be delicious.

Q: Can I use frozen vegetables?
A: Absolutely! Just add them directly to the soup without thawing, but you may need to adjust the cooking time slightly.

Q: Why did my cheese clump up?
A: This usually happens when the heat is too high or the cheese is added too quickly. Make sure your heat is on low and add the cheese gradually, stirring constantly.

Q: Can I make this in a slow cooker?
A: Yes, but add the dairy products in the last 30 minutes of cooking to prevent curdling.

Q: How can I make the soup thicker?
A: Create a slurry with equal parts cornstarch and cold water, then stir it into the simmering soup until it reaches your desired consistency.
