Broccoli Cheddar Soup

A warm bowl of creamy soup feels especially inviting when the cheese has melted into the broth and tender pieces of broccoli and carrot show through every spoonful. This Broccoli Cheddar Soup combines sharp cheddar, Parmesan, fresh vegetables, and a lightly seasoned cream base without requiring a long afternoon at the stove.

Most of the cooking happens in one 4-quart pot, and an immersion blender creates a smooth base while leaving some vegetables chunky. It’s rich enough for a cozy lunch or simple dinner, yet the complete recipe takes about 20 minutes when the vegetables are prepared efficiently.

• Sharp cheddar and Parmesan create a rich, savory cheese flavor.
• One batch makes six servings for lunch or a casual dinner.

Ingredients

• 1 Tbsp butter (14 g)
• 1 small onion, diced
• 1 cup diced carrot (240 mL by volume)
• 3 cups broccoli florets (710 mL by volume)
• 2 cups chicken broth (475 mL)
• ½ tsp dried thyme leaves
• ½ tsp garlic powder
• ¼ tsp salt
• ¼ tsp black pepper
• 2 Tbsp all-purpose flour (16 g)
• 1½ cups half-and-half or light cream (355 mL)
• 1 cup freshly shredded sharp cheddar cheese (4 ounces/113 g)
• ⅓ cup shredded Parmesan cheese (1 ounce/28–30 g)

Use evenly sized broccoli florets and diced carrots so they become tender within the short simmering time. Freshly shredding the cheddar helps it melt smoothly into the hot soup.

How to Make This Recipe

Step 1: Soften the Onion and Carrot

Melt the butter in a heavy-bottomed 4-quart saucepan or Dutch oven over medium heat. Add the diced onion and carrot, then cook for about 3 minutes. Stir regularly until the onion softens but doesn’t become deeply browned.

Pro Tip: Keep the carrot pieces small and even. Large pieces may remain firm after the broccoli is ready.

Step 2: Simmer the Broccoli and Seasonings

Add the broccoli florets, chicken broth, dried thyme, garlic powder, salt, and black pepper. Bring the mixture to a simmer and cook for about 8 minutes. The broccoli should be tender enough for an immersion blender to break down easily, without becoming dull and mushy.

Remove 1 cup of the cooked vegetables, coarsely chop them, and set them aside. These pieces will return to the pot later and give the creamy soup a pleasantly chunky texture.

Step 3: Blend and Thicken the Soup

Blend the vegetables and broth remaining in the pot with an immersion blender until relatively smooth. Place the flour in a small heat-safe bowl, then gradually stir in the half-and-half or light cream until the mixture is smooth and free of visible flour lumps.

Bring the blended soup base to a boil. Whisk in the cream mixture and continue whisking for 3–4 minutes, until the soup looks thick and bubbly.

Pro Tip: Adding the cream gradually to the flour is important. Pouring all the liquid over the flour at once can leave stubborn lumps in the finished soup.

Step 4: Melt in the Cheese and Serve

Remove the saucepan from the heat. Stir in the freshly shredded sharp cheddar, Parmesan, and reserved vegetables until both cheeses melt completely. The finished Broccoli Cheddar Soup should look creamy and cohesive, with tender vegetable pieces distributed throughout.

Serve immediately. Don’t boil the soup after adding the cheese; excessive heat can cause the dairy to separate and give the soup an oily or grainy consistency.

Pro Tip: If the cheese needs another moment to melt, keep stirring off the heat. The soup will still be hot enough to finish the job.

Expert Tips for Better Results

• Cut the broccoli into small, evenly sized florets so it becomes tender during the 8-minute simmer.
• If using broccoli stems, peel or cut away the tough outer portion before chopping them.
• Shred the cheddar shortly before cooking to encourage smooth, even melting.
• Use a heavy-bottomed pot to distribute heat more evenly while the thickened soup bubbles.
• Blend carefully while keeping the immersion blender head below the liquid to reduce splashing.
• Serve the soup soon after adding the cheese because extended heating or holding can change its consistency.

Variations

• Frozen broccoli: Use 3 cups frozen broccoli florets without thawing them first. Continue with the same simmering method and cook until tender enough to blend.
• Vegetarian version: Replace the 2 cups chicken broth with 2 cups vegetable broth. The flavor will depend more heavily on the strength and seasoning of the selected broth.
• Light cream option: Use 1½ cups light cream in place of half-and-half, as permitted in the ingredient list. The finished soup remains creamy and rich.

Serving Suggestions

• Serve the soup with crusty bread for dipping into the thick, creamy broth.
• Pair it with a simple green salad to add a crisp contrast to the rich cheese base.
• Offer toasted bread alongside each bowl for a warm, satisfying lunch.
• Serve smaller portions before a simple roasted chicken or vegetable dinner.
• Ladle it into warmed bowls so the cheese stays fluid and creamy at the table.

Storage and Reheating

• Room temperature: Refrigerate the soup promptly after serving rather than leaving the dairy-based soup at room temperature for an extended period.
• Refrigeration: Transfer leftovers to a covered container and refrigerate for up to 4 days.
• Freezing: Freezing isn’t recommended because the dairy and cheese may separate or develop a grainy texture.
• Thawing: No thawing method is recommended because the soup shouldn’t be frozen.
• Stovetop reheating: Warm the soup over medium-low heat, stirring frequently, until it reaches 165°F (74°C). Don’t let it boil.
• Microwave reheating: Heat in short intervals, stirring occasionally, until the center reaches 165°F (74°C). Gentle reheating helps preserve the creamy texture.
