Broccoli cheddar soup is the kind of meal that makes the whole house smell incredible before you even sit down. This recipe gives you a rich, velvety, and deeply cheesy bowl that beats any restaurant version, and it comes together in just 30 minutes. I’ve made it so many times that it’s basically written into our family’s cold-weather routine.
I still remember the first time I made this on a chilly Tuesday night with nothing but a head of broccoli and a block of sharp cheddar in the fridge. What came out of that pot was so good, my kids asked for it two nights in a row. That is when I knew this broccoli cheddar soup needed a permanent spot in our dinner rotation.
The secret is in the balance. Plenty of broccoli, a bold sharp cheddar, a perfectly seasoned base with smoked paprika and dry mustard, and a creamy sauce that stays smooth and silky. No blending. No shortcuts. Just real, honest comfort food that your family will ask for again and again. You are going to love this one!

Ingredients for Broccoli Cheddar Soup
I always grate my cheddar fresh from a block for this recipe. In my experience, pre-shredded cheese has anti-caking coatings that prevent smooth melting and can leave you with a grainy, separated sauce. Sharp cheddar is my go-to here because it gives the soup that bold, tangy flavor that truly stands out. Have all your vegetables prepped before you heat the pot since this recipe moves quickly once you start.
- 1/3 cup butter
- 1 large onion (chopped)
- 1 3/4 tsp kosher salt
- 3/4 tsp black pepper
- 3/4 tsp dry mustard powder – I recommend this for its ability to enhance cheddar flavor naturally
- 1/8 to 1/4 tsp cayenne pepper
- 3/4 tsp smoked paprika – Pro tip: this is the ingredient that takes the flavor from ordinary to outstanding
- 2 cloves garlic (smashed and minced)
- 1/3 cup all-purpose flour
- 3 cups low-sodium chicken broth
- 3 cups whole milk (or half and half)
- 3 large heads broccoli, about 8 cups chopped including stems (about 1.5 lbs) – My preference is to keep the stems, they cook up tender and add great texture
- 3 carrots (shredded or cut into matchsticks)
- 1/2 to 1 cup heavy cream
- 4 cups sharp cheddar cheese, packed and freshly grated (about 14 to 16 oz) – I usually add it one cup at a time for the smoothest melt
- Extra shredded cheddar cheese, for garnish
- Chopped green onions, for garnish
Step-by-Step Instructions
I recommend prepping every single ingredient before you turn on the stove. This recipe moves fast and having everything ready keeps the process relaxed and enjoyable.
Step 1: Chop the broccoli into bite-sized florets and do not throw away those stems. Slice them into small pieces and they will cook up perfectly tender. Shred or matchstick the carrots, chop the onion, and mince the garlic. Set everything aside.
Step 2: In a large soup pot, melt the butter over medium heat. Add the chopped onion along with the salt, pepper, dry mustard powder, cayenne, and smoked paprika. Stir to combine and saute until the onion is soft and translucent, about 4 to 5 minutes. Add the minced garlic and cook for one more minute until fragrant.
Step 3: Sprinkle the flour over the onion mixture a little at a time, stirring after each addition until it is fully absorbed into the butter and forms a smooth paste. This roux is what gives your soup its rich, thick body.
Step 4: Using a whisk, slowly pour in the chicken broth a little at a time, stirring constantly after each addition. Go slow here. Adding liquid too fast will prevent your sauce from becoming creamy and smooth. Once all the broth is incorporated, continue the same process with the whole milk, whisking until everything is combined.
Step 5: Increase heat to medium-high and bring to a low simmer. Add the broccoli and carrots. Once you see small bubbles forming, reduce the heat back to low and maintain a gentle simmer. Cook for 5 to 10 minutes until the broccoli is just barely tender. Do not let the soup reach a rolling boil or the dairy can separate and turn grainy.
Step 6: Turn off the heat. Stir in 1/2 cup of heavy cream. Add the freshly grated cheddar one cup at a time, stirring until fully melted before adding the next cup. If the cheese is not melting, return the heat to low just until it melts, then turn it off right away. Taste and adjust seasoning. Add the remaining cream if you want it richer. Serve immediately topped with extra cheddar and chopped green onions.

How to Store and Reheat Your Soup
Let the soup cool completely before transferring to an airtight container. It keeps well in the refrigerator for 3 to 5 days. For longer storage, freeze in a freezer-safe bag or container for up to 3 months. Label it with the date so nothing gets forgotten.
When reheating, always use the stovetop over low heat. Stir gently and go slow. The soup will thicken significantly in the fridge as the cheese sets and the broccoli absorbs liquid, so add a splash of broth, milk, or cream to bring it back to the right consistency. Do not microwave from frozen and avoid high heat at any stage or the sauce can curdle and lose its silky texture.
Pro tip: reheat only the portion you plan to eat rather than the whole batch. This keeps the texture much better over multiple days and prevents repeated heating from breaking down the cheese sauce.
Frequently Asked Questions
Can I use frozen broccoli instead of fresh?
Yes, frozen broccoli works fine. Add it during the last 3 to 5 minutes of simmering to prevent it from turning mushy. No need to thaw it first, just toss it in straight from the bag.
Why is my soup grainy or separated?
This almost always comes from one of two things: pre-shredded cheese or heat that is too high. Always grate your cheese fresh from a block and keep the heat on low when adding it. Adding it one cup at a time also helps it melt evenly into the sauce.
Can I make this soup vegetarian?
Absolutely. Just swap the chicken broth for vegetable broth. Everything else stays exactly the same and the flavor is still rich and satisfying. This is a great option for meatless Monday or when cooking for mixed groups.
