Ingredients for Easy Cream of Broccoli Soup

This simple broccoli cheddar soup recipe uses accessible ingredients you likely already have. Measurements are precise for consistent results:

Ingredient	Amount	Substitution Options
Fresh broccoli	4 cups florets (about 1 large head)	Frozen broccoli (thawed)
Yellow onion	1 medium, finely diced	Shallot or leek
Garlic	2 cloves, minced	1/2 tsp garlic powder
Unsalted butter	3 tbsp	Olive oil (for dairy-free)
All-purpose flour	3 tbsp	Rice flour (gluten-free)
Vegetable broth	4 cups	Chicken broth
Whole milk	1 cup	Half-and-half or coconut milk

Step-by-Step Instructions for Perfect Soup

1. Prep vegetables: Cut broccoli into uniform florets. Finely dice onion and mince garlic.
2. Sauté aromatics: Melt butter in a large pot over medium heat. Add onion and cook until translucent (5 minutes). Add garlic and cook 1 minute until fragrant.
3. Create roux: Sprinkle flour over onions and whisk constantly for 2 minutes until golden. This eliminates raw flour taste.
4. Add liquid gradually: Slowly pour in 1 cup broth while whisking continuously to prevent lumps.
5. Build soup base: Add remaining broth and broccoli. Bring to simmer, then reduce heat and cook covered for 15 minutes until broccoli is tender.
6. Blend smoothly: Use an immersion blender to puree until smooth (or carefully transfer to countertop blender).
7. Add dairy: Return to low heat and stir in milk. Heat gently (do not boil) for 5 minutes to thicken.
8. Season: Add salt, pepper, and optional pinch of nutmeg. Taste and adjust seasoning.

Pro Tips for the Best Results

These professional techniques transform a simple recipe into exceptional soup:

• Don't skip the roux cooking time—2 minutes ensures no floury taste while maintaining thickening power
• Cut broccoli uniformly so all pieces cook at the same rate
• Heat dairy gently to prevent curdling—never bring milk-based soups to a full boil
• Add acid at the end—a squeeze of lemon brightens flavors if the soup tastes flat
• For extra richness, stir in 1/4 cup shredded sharp cheddar at the end (creates easy broccoli cheddar soup)

Common Questions Answered

Here are solutions to frequent challenges with cream of broccoli soup:

• Why is my soup grainy? You likely added cold liquid to hot roux too quickly. Always temper by adding small amounts of warm broth while whisking.
• Can I use frozen broccoli? Yes! Thaw completely and pat dry to prevent watery soup.
• How do I make it thicker? Simmer uncovered for 5-10 minutes or make a slurry of 1 tbsp cornstarch + 2 tbsp cold broth.
• Why did my soup separate? Dairy was added to boiling liquid. Always reduce heat before adding milk products.
• Can I make this in a slow cooker? Sauté aromatics first, then transfer to slow cooker with other ingredients (except milk) and cook on high 3-4 hours. Add milk before serving.

This easy cream of broccoli soup recipe proves that simple ingredients, when treated properly, create extraordinary results. The technique-focused approach ensures consistent success whether you're a beginner or experienced cook. Unlike recipes that rely on canned soup shortcuts, this from-scratch method delivers pure broccoli flavor with luxurious texture. Make a double batch—it freezes beautifully and makes weeknight dinners effortless. Serve with crusty bread for a complete meal that looks impressive but requires minimal effort.

Can I make cream of broccoli soup without using cream of mushroom?

Yes, this recipe creates creamy texture using a roux (butter and flour) with milk instead of relying on cream of mushroom soup. The roux method provides better flavor control and avoids the metallic taste of canned soup bases.

How do I prevent my broccoli soup from becoming grainy?

Prevent graininess by properly cooking the roux for 2 minutes, gradually adding warm broth while whisking constantly, and ensuring broccoli is fully tender before blending. Never add cold liquid to a hot roux as this causes clumping.

What's the best way to store leftover broccoli soup?

Store cooled soup in airtight containers in the refrigerator for up to 4 days. For longer storage, freeze in portion-sized containers for up to 3 months. When reheating, add small splashes of broth or milk if the soup has thickened too much.

Can I make this broccoli soup dairy-free?

Absolutely. Substitute olive oil for butter and use full-fat coconut milk instead of dairy milk. For the roux, use rice flour instead of all-purpose flour to keep it gluten-free and dairy-free. The coconut flavor will be subtle and complements the broccoli well.

Why did my soup separate after adding milk?

Soup separates when dairy is added to boiling liquid. Always reduce heat to low before adding milk, and never let the soup return to a full boil after dairy is incorporated. Gentle reheating also prevents separation when serving leftovers.
