This Best Broccoli Cheddar Soup Recipe Slaps: Creamy, Cozy, and Done in 30

You know that soup that makes you feel like you’ve got life figured out? This is it. It’s thick, rich, super cheesy, and somehow still loaded with veggies so you can claim it’s “healthy-ish.” No runny broth, no weird grainy cheese—just velvety perfection that tastes like your favorite café, minus the $12 price tag.

I tested the ratios so you don’t have to, and yes, it reheats like a dream. Ready to make your cold-weather flex in one pot?

Why This Recipe Works

Right balance of fat, dairy, and heat control. The combo of butter, flour, and whole milk creates a sturdy base that stays smooth when you add cheese. No curdling, no clumps.

Sharp cheddar for punch, a touch of Parmesan for depth. Sharp cheddar gives that classic flavor; Parmesan adds umami without turning it into Alfredo.

Blended just enough. We purée half the soup for a creamy texture and keep half chunky for bite.

Best of both worlds—silky spoonfuls with real broccoli pieces.

Brief simmer, not a boil. Gentle heat preserves the broccoli’s color and the cheese’s texture. High heat is how you ruin good soup fast.

Ingredients Breakdown

Butter (4 tbsp) – For sautéing and building the roux. Flavor + body.
Yellow onion (1 medium, diced) – Sweet, mellow base that rounds out the cheese.
Garlic (3 cloves, minced) – Big flavor in small doses.
All-purpose flour (1/4 cup) – Thickens the soup without making it gummy.
Chicken or vegetable stock (3 cups) – Use low-sodium so you can control the salt.
Whole milk (2 cups) – Creaminess without heavy cream heaviness.
Broccoli (5 cups florets, finely chopped) – Fresh is best; stems peeled and chopped are welcome.
Carrot (1 large, grated) – Classic color and a hint of sweetness.
Sharp cheddar cheese (12 oz, freshly grated) – Freshly grated melts smoother than bagged.
Parmesan (1/4 cup, finely grated) – Optional but recommended for savory depth.
Dijon mustard (1 tsp) – Quietly boosts cheese flavor.
No, it won’t taste like mustard.
Smoked paprika (1/2 tsp) – Adds warmth and a subtle smoky note.
Nutmeg (1/8 tsp) – Tiny pinch wakes up dairy-based soups.
Kosher salt and black pepper – To taste. Start small; adjust at the end.
Optional: Red pepper flakes (pinch) – For a little heat.

Let’s Get Cooking – Instructions

Sweat the aromatics. In a large pot over medium heat, melt the butter. Add onion and a pinch of salt.
Cook 5–6 minutes until translucent. Stir in garlic; cook 30 seconds until fragrant.
Make the roux. Sprinkle in the flour and stir constantly for 1–2 minutes until the mixture smells toasty and looks like wet sand. Don’t brown it.
Add liquids gradually. Whisk in the stock slowly to avoid lumps, then add the milk.
Bring to a gentle simmer, stirring often. Keep it below a boil.
Vegetable time. Stir in broccoli and grated carrot. Simmer uncovered 8–10 minutes until the broccoli is tender but still green.
Season with 1/2 tsp salt and a few grinds of pepper.
Blend for texture. Using an immersion blender, blend about half the pot to thicken while keeping chunks. No immersion blender? Carefully transfer 2 cups to a blender, purée, and return to pot.
Flavor boosters. Stir in Dijon, smoked paprika, and nutmeg.
Taste, then adjust salt and pepper.
Cheese goes in last. Reduce heat to low. Add cheddar in small handfuls, stirring until melted before adding more. Fold in Parmesan.
Do not boil after adding cheese—grainy city.
Serve. Ladle into bowls. Optional: top with extra cheddar, a crack of pepper, and a drizzle of good olive oil or a few croutons. Victory tastes cheesy.

Storage Instructions

Fridge: Cool completely, then store in airtight containers for 3–4 days.
Reheat: Warm gently over low heat, stirring often.
If it’s too thick, splash in stock or milk. Avoid boiling.
Freezer: Technically possible up to 2 months, but dairy can separate. If freezing, undercook the broccoli slightly and reblend after thawing for best texture.

Nutritional Perks

Broccoli brings fiber, vitamin C, and vitamin K, plus plant compounds that support overall health.
Cheddar adds protein and calcium—satisfying and bone-friendly.
Reasonable fats from butter and cheese make it filling, so smaller portions still feel like a meal.
Smart swaps available (see Mix It Up) if you want lighter without losing vibe.

Common Mistakes to Avoid

Boiling after adding cheese. This breaks the emulsion and turns your soup gritty.
Low heat only.
Using pre-shredded cheese. Anti-caking agents block melting. Freshly grate for silky results. Seriously.
Skipping the roux. Cornstarch alone won’t give that classic body and mouthfeel.
Overcooking the broccoli. Gray broccoli is a vibe killer.
Tender, not mushy.
Under-seasoning. Cheese is salty, but the base still needs salt. Taste at the end and adjust.

Mix It Up

Lighter version: Use 1 tbsp butter + 1 tbsp olive oil; swap half the milk for unsweetened cashew milk; reduce cheddar to 8 oz. Still creamy, less rich.
Extra veg: Add 1 cup cauliflower florets with the broccoli—blends super smooth.
Protein boost: Stir in 1 cup cooked shredded chicken or crumbled cooked bacon at the end.
Not mad about it.
Heat lovers: Add 1–2 tsp hot sauce or a pinch of cayenne with the spices. Balanced, not fiery.
Gluten-free: Swap flour with 2 tbsp cornstarch. Whisk into cold milk first, then add to the pot.
Ultra-smooth: Fully blend the soup and strain for a restaurant-level texture.
Crouton topper: Cube day-old bread, toss with olive oil, garlic powder, and salt; toast at 375°F for 8–10 minutes.
Crunch factor: elite.

FAQ

Can I use frozen broccoli?

Yes. Use the same amount, but add it straight from frozen and simmer a couple extra minutes. It’ll be softer than fresh, so consider blending a bit less.

What cheddar is best?

Sharp or extra-sharp cheddar, block style, freshly grated.

White or orange both work. Mild cheddar melts fine but tastes flat, IMO.

How do I fix grainy soup?

Take it off the heat immediately and whisk in a splash of warm milk or stock. Blend a cup of soup and stir it back in.

Next time, lower the heat before adding cheese and add in small handfuls.

Can I make it vegetarian?

Absolutely. Use vegetable stock and skip any bacon add-ins. The flavor stays big thanks to the Parmesan and spices.

How thick should it be?

Coat-the-spoon thick but pourable.

If it’s too thick, loosen with warm stock or milk. Too thin? Simmer a few more minutes or blend a bit more.

Is heavy cream better than milk?

It’s richer but not necessary.

Whole milk keeps it balanced; heavy cream can make it too heavy. If you want extra luxe, swap 1/2 cup of the milk for cream.
