Recipe Overview
Time: 40 Minutes
Ingredients: Vegetable broth, milk, broccoli florets, matchstick carrots, yellow onion, sharp cheddar cheese, butter, garlic, flour, Dijon mustard, salt, pepper, French baguette, & olive oil,
Ease: Medium. Simple ingredients and steps, just a few more than your average recipe.
Ingredients & Substitutions
- Broccoli Florets - Fresh is best, but frozen works too. If you want to use frozen, thaw and drain first, then chop any larger pieces into smaller pieces. It will also require 5-10 minutes of less cook time.
- Matchstick Carrots - I like using pre-grated matchstick carrots to save time.
- Onion - Yellow or sweet onions work great for this soup. White onion will give you a slightly stronger flavor.
- Vegetable Broth - You can also use chicken broth for a more savory flavor.
- Milk - Whole milk makes the soup creamier. You can use 2% or skim, but the soup will be a little thinner.
- Garlic - Fresh garlic gives the best flavor for both the soup and the croutons. If needed, you can swap one garlic clove for ½ teaspoon garlic powder.
- All-Purpose Flour - Helps thicken the soup. Whole wheat flour works as well.
- Dijon Mustard (Optional) - It adds a subtle tang that balances the cheese.
- Sharp cheddar cheese - Sharp cheddar gives the strongest cheesy flavor. I like using yellow cheddar, but white cheddar works too.
- French baguette - I like using a thin baguette so the croutons get extra crisp. You can also use sourdough, ciabatta, or any sturdy bread you have on hand.

How to Make Broccoli Cheddar Soup & Croutons
Cook the Veggies
Melt butter, cook the onion until soft, then add garlic. Sprinkle in the flour and whisk for 1-2 minutes.
Build the Soup
Slowly whisk in the broth, then add the milk, broccoli, carrots, Dijon, salt, and pepper. Simmer for about 20 minutes, until the broccoli is tender.
Make the Croutons
Toss torn bread with melted butter, garlic, and oil, then bake, flipping halfway, until crisp and golden.
Finish the Soup
Stir in the cheddar a handful at a time until the soup is smooth and creamy. Season with salt and pepper.
Tips
Chop the broccoli small: Bite-sized pieces cook faster and give the soup a better texture.
Don't boil the soup after adding cheese: Keep the heat low to prevent the cheese from separating.
Want it thicker? Mix 1-2 tablespoons of flour with the same amount of milk, then whisk in and cook for 5 more minutes.
Too thick? Add a splash of broth or milk until it reaches your ideal consistency.
Common Questions
Yes. Thaw it first and drain off excess liquid so the soup doesn't become watery.
This usually happens when the soup gets too hot. Try whisking in a splash of milk or cream over low heat to help cool and smooth it out. Sometimes adding a bit more freshly grated cheese, on low heat, can help it come back together.
Shredded or diced chicken works great, and crispy bacon adds extra flavor. You can also stir in cooked ham or cooked turkey if you have leftovers.
You can use half-and-half for an even creamier soup, or 2%, 1%, and skim milk for a lighter option. Unsweetened almond milk works, but it will change the flavor.
Add 1-2 cups of diced potatoes, cut into small ½-inch pieces, along with the broccoli. They'll cook in about the same amount of time and make the soup heartier.
Make Ahead
For the Next 2-4 Days:
- Make the soup and croutons as directed.
- Store the soup in an airtight container in the fridge for up to 4 days.
- Store the croutons in a sealed container for 2-3 days.
- Reheat the soup on the stove over medium-low heat or in the microwave. Add a splash of milk or broth if it thickens in the fridge.
For the Next 3 Months:
- Make the soup as directed, let it cool completely, then freeze for up to 3 months.
- To reheat, thaw in the fridge overnight, then warm gently on the stove over medium-low heat or in the microwave. Add a little milk or broth as needed.
- Croutons are best made fresh, but you can make them 3-4 days ahead and store in an airtight container. They don't freeze well, they lose their crunch.
