Cheesy Broccoli Soup is that perfect bowl of comfort made creamy with melted cheese and packed with tender broccoli. It’s smooth, rich, and has just the right amount of cheesy goodness that makes it so satisfying on cool days. The hint of warmth from the soup wraps around you like a cozy blanket.
I’ve always loved how simple ingredients come together to create something so tasty and comforting in this soup. What makes it extra special for me is the way the broccoli keeps a little bite so you get both creamy and chunky textures in every spoonful. I like to add a sprinkle of extra cheese on top—it just makes it feel like a little treat every time.
This soup is great on its own, but I especially enjoy it with a side of crusty bread or a grilled cheese sandwich to dip in. It’s the kind of meal that feels like a warm hug, perfect for lunch or dinner when you want something easy but still filling and tasty. Whenever I make it, my family asks for seconds, and I’m happy to give it to them!
Key Ingredients & Substitutions
Broccoli: Fresh broccoli gives the best flavor and texture. You can use frozen if fresh isn’t available, but thaw it first and drain well to avoid watery soup.
Butter & Flour (Roux): Butter and flour work together to thicken the soup. If dairy-free, try coconut oil with gluten-free flour for a similar effect.
Chicken Broth: Chicken broth adds depth, but vegetable broth works well for a meatless option. Use low-sodium broth to control saltiness.
Cheddar Cheese: Sharp cheddar melts nicely and adds a bold flavor. Try gouda or Monterey Jack for a milder taste or a mix for creaminess.
Dijon Mustard: A small touch of mustard helps balance the cheese richness. If you don’t have Dijon, a pinch of dry mustard powder will work.
How Do I Make a Smooth, Creamy Soup Without Clumps?
The key to a smooth and creamy soup is in the roux and slow whisking. Here’s what I do:
- Melt butter and cook the onions, then add flour and whisk constantly for a few minutes to cook out the raw taste.
- Add broth and milk slowly while whisking, so the flour blends in without clumping.
- Simmer gently to let the mixture thicken before adding broccoli.
- When adding cheese, remove soup from heat and stir constantly to ensure smooth melting without clumping.
Using an immersion blender partially helps avoid lumps while leaving some broccoli chunks for a nice texture contrast.
Equipment You’ll Need
- Large heavy-bottomed pot – perfect for even heat and easy stirring without burning the soup.
- Wooden spoon or silicone spatula – great for stirring the roux and soup gently.
- Whisk – helps mix the flour into the butter and liquids smoothly, preventing lumps.
- Immersion blender – handy for blending the soup directly in the pot to your preferred texture.
- Cutting board and sharp knife – for chopping broccoli, onion, and garlic easily and safely.
Flavor Variations & Add-Ins
- Swap sharp cheddar for smoked cheddar or gouda for a richer, smokier flavor.
- Add cooked bacon or ham pieces for extra savory bites and a meaty touch.
- Stir in a cup of cooked rice or small pasta to make the soup more filling.
- Mix in sautéed mushrooms or cauliflower for more veggie variety and texture.

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare and around 20 minutes to cook, so expect to spend about 30 minutes total from start to finish. It’s a quick and cozy meal you can whip up any day of the week!
Step-by-Step Instructions:
1. Cook the Onions and Garlic:
In a large pot, melt the butter over medium heat. Add the finely chopped onion and cook it gently until soft and translucent, about 4-5 minutes. Then, add the minced garlic and cook for another minute until it smells great.
2. Make the Roux:
Sprinkle the flour over the onion and garlic mixture. Whisk constantly for 2-3 minutes to cook out the floury taste and create a smooth roux that will help thicken your soup.
3. Add Liquids and Thicken:
Slowly whisk in the chicken broth and milk, stirring well to avoid lumps. Bring everything to a gentle simmer and let it thicken slightly, which should take about 5-7 minutes.
4. Cook the Broccoli:
Add the fresh broccoli florets into the pot. Cover and allow them to cook until tender but still bright green, about 6-8 minutes.
5. Blend the Soup:
Using an immersion blender, carefully puree part of the soup right in the pot until you get the texture you like—smooth but with some broccoli chunks for a nice bite. If you don’t have an immersion blender, blend half the soup in a regular blender, then stir it back in.
6. Add Cheese and Finish:
Stir in the shredded cheddar cheese and Dijon mustard until the cheese melts and your soup becomes creamy and rich. Season with salt, pepper, and add a pinch of nutmeg if you like.
7. Serve and Enjoy:
Ladle the hot soup into bowls. For a little extra treat, top with more shredded cheddar or a sprinkle of cracked black pepper. Serve with crusty bread or crackers for dipping. Enjoy your warm, cheesy, broccoli-filled comfort!
Can I Use Frozen Broccoli Instead of Fresh?
Yes! Just make sure to thaw and drain the frozen broccoli well before adding it to the soup to prevent extra wateriness. It may cook a little faster, so keep an eye on it.
Can I Substitute the Milk for a Dairy-Free Alternative?
Absolutely. Use unsweetened almond milk, oat milk, or any other dairy-free milk you prefer. Choose full-fat versions for creamier results and avoid flavors that could alter the soup’s taste.
How Do I Store Leftover Soup?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or microwave, stirring occasionally to keep the soup smooth and creamy.
Can I Make Cheesy Broccoli Soup Ahead of Time?
Yes! You can prepare the soup a day in advance. When reheating, warm it slowly and stir in extra cheese if needed to refresh the creaminess before serving.
