Broccoli Cheddar Soup (Lightened Up)

Lightened up broccoli cheddar soup in a white bowl with melted cheddar

This lightened-up broccoli cheddar soup is just as rich and cheesy as the original, but without the heavy cream weighing you down. ♡

The secret is using milk instead of cream and letting the vegetables do the thickening work. A quick blend gives you that silky Panera-style texture, and sharp cheddar melted in at the end means you need less cheese for maximum flavor.

Grab a head of broccoli and your favorite sharp cheddar. Let’s make it together.

Step by step process of making broccoli cheddar soup

How to Make Broccoli Cheddar Soup (Lightened Up)

  1. Sauté. Melt butter in a large pot over medium heat. Add the onion, garlic, and carrot and cook 4 to 5 minutes until softened.
  2. Thicken. Sprinkle the flour over the vegetables and stir constantly for 1 minute to cook out the raw flour taste. Slowly pour in the broth while whisking to prevent lumps.
  3. Simmer. Add the broccoli florets and milk. Bring to a gentle simmer and cook for 12 to 15 minutes until the broccoli is very tender.
  4. Blend. Use an immersion blender to blend about two-thirds of the soup until smooth, leaving some chunks for texture. (Or transfer half to a blender and return to the pot.)
  5. Melt. Remove from heat and stir in the shredded cheddar and mustard powder until the cheese is completely melted and smooth. Season with salt and pepper.

Tips

  • Shred the cheddar yourself from a block. Pre-shredded cheese has anti-caking agents that prevent smooth melting.
  • Use sharp or extra-sharp cheddar. Stronger cheese means you can use less for the same flavor.
  • Add the cheese off the heat. If the soup is too hot, the cheese can get grainy instead of smooth.
  • Don’t over-blend. Leaving some broccoli chunks gives the soup great texture.
  • The carrot adds natural sweetness and helps thicken the soup without extra cream.

Variations

  • Add a pinch of nutmeg for a classic French touch.
  • Stir in cooked bacon bits for a smoky, savory version.
  • Use cauliflower instead of half the broccoli for an even lighter soup.
  • Make it gluten-free by using cornstarch instead of flour (mix with cold milk first).
  • Add a splash of white wine with the broth for extra depth.

FAQ

Simmer it uncovered for a few extra minutes to reduce. You can also add an extra tablespoon of flour in the thickening step. Blending more of the soup also makes it thicker.
Gruyere or white cheddar both work well. Avoid soft cheeses like brie or cheese with low melting points. The cheese should be something that melts smoothly.
Dairy-based soups can separate when frozen. It’s best eaten fresh or stored in the fridge for up to 4 days. If you do freeze it, reheat gently and whisk well.
Yes, swap the chicken broth for vegetable broth. Everything else stays the same. The cheese and butter give it plenty of richness.
