Ingredients for Potbelly Broccoli Cheddar Soup

Simple ingredients come together to create this creamy broccoli cheddar soup.

For the best flavor, use high-quality vegetarian broth—homemade or store-bought. I prefer Pacific Foods or Imagine Foods for their rich, savory taste. If using frozen broccoli, thaw and drain well to avoid excess moisture. Fresh broccoli works too—just chop it into small florets.

No half-and-half? Heavy cream or a mix of milk and cream works as a substitute. For an extra creamy soup, add more cheddar cheese or a splash of cream. If you like a bit of spice, add a pinch of cayenne pepper. The carrot adds a touch of sweetness—feel free to omit if you prefer.

This soup stores well in the fridge for up to 4 days and freezes nicely for 3 months. Reheat gently on the stovetop, adding a splash of cream or broth if it thickens too much. For the best texture, reheat slowly and stir frequently.

Step-by-Step Instructions for Potbelly Broccoli Cheddar Soup

Here’s the method to create this creamy, comforting soup that’ll become your new favorite.

Step 1: Sauté the Aromatics

Start by melting the 4 tbsp Unsalted Butter in a large pot over medium heat. Once it’s fully melted and starting to foam, add the 1 whole Medium Onion, chopped, and cook for 5-7 minutes until it becomes translucent and starts to caramelize. You’ll know it’s ready when the onion is soft and fragrant.

Next, add the 4 cloves Garlic Cloves, minced, and cook for another 1 minute, stirring constantly to prevent burning. The garlic should be fragrant and just starting to turn golden. Be careful not to let it burn, as this can quickly ruin the flavor.

Step 2: Create the Roux and Add Broth

Sprinkle the 0.25 cup All-Purpose Flour over the onion and garlic mixture, stirring constantly to create a smooth roux. Cook for 1-2 minutes until the flour is lightly golden and has a nutty aroma. This step is crucial for thickening the soup.

Gradually whisk in the 2 cups Chicken Broth, making sure to scrape up any browned bits from the bottom of the pot. Bring the mixture to a simmer and cook for 2-3 minutes until it thickens slightly. If you’re using vegetarian broth, it’s a great alternative that still packs plenty of flavor.

Step 3: Add Vegetables and Simmer

Add the 4 cups Broccoli Florets and 1 whole Carrot, peeled and grated, to the pot. Stir well to combine, then reduce the heat to low and let it simmer for 15-20 minutes, or until the vegetables are tender. The broccoli should be bright green and the carrot should be easily pierced with a fork.

During this time, the flavors will meld together, and the soup will start to take on that creamy, comforting quality you’re looking for. Be patient and let it cook slowly to develop the best flavor.

Step 4: Blend and Add Creaminess

Using an immersion blender, carefully blend the soup until it’s mostly smooth, leaving some chunks of broccoli for texture. If you don’t have an immersion blender, you can transfer the soup in batches to a regular blender, then return it to the pot.

Stir in the 1 cup Half-and-Half (or heavy cream for an even richer version) and let it heat through for 2-3 minutes. The soup should now be creamy and smooth, with a velvety texture that coats the back of a spoon.

Step 5: Finish with Cheese and Seasonings

Add the 2 cups Sharp Cheddar Cheese, shredded, in batches, stirring until each batch is fully melted before adding the next. This ensures a smooth, creamy texture without any clumps. Stir in the 1 tsp Dried Mustard, 0.5 tsp Paprika, 1 tsp Salt, and 0.5 tsp Black Pepper to enhance the flavor.

Taste and adjust the seasoning as needed. Serve hot, garnished with additional cheddar cheese if desired. This soup is perfect for a comforting meal on a chilly day, and it’s sure to become a family favorite.

Common Mistakes When Making Perfect Results

Overcooking the Broccoli

One of the most common mistakes when making broccoli cheddar soup is overcooking the broccoli, which results in an unpleasant, mushy texture and a loss of vibrant green color. To avoid this, add the broccoli florets towards the end of the cooking time and monitor their tenderness closely. I prefer my broccoli to retain some crunch, so I cook it for 5-7 minutes until it’s tender but still bright green 🔥.

Incorrect Roux Preparation

A proper roux is crucial for achieving the right consistency in your broccoli cheddar soup. Avoid adding the flour too quickly, as this can create lumps. Instead, gradually sprinkle it over the butter and onion mixture while stirring constantly. Cook the roux for 1-2 minutes until it’s lightly golden to remove any raw flour taste.

Curdling the Cream

When adding the half-and-half or heavy cream, it’s essential to temper it properly to prevent curdling. Gradually add a small amount of the warm soup to the cream while whisking, then slowly pour the tempered cream into the pot. This technique ensures a smooth, creamy texture that remains stable even when reheated.

Insufficient Seasoning

Broccoli cheddar soup can be quite bland if not seasoned properly. Don’t be shy with the salt and pepper – taste and adjust frequently throughout the cooking process. I also recommend adding a pinch of dried mustard and paprika to enhance the flavor profile and give it that signature Potbelly taste.

Using Low-Quality Cheese

The quality of your cheddar cheese significantly impacts the final flavor of your soup. Avoid pre-shredded cheese that contains anti-caking agents, which can affect the texture. Instead, opt for a high-quality, sharp cheddar that you shred yourself. This will result in a richer, more authentic flavor that makes your broccoli cheddar soup truly special.

Not Blending Properly

To achieve that signature creamy texture, it’s crucial to blend the soup correctly. Using an immersion blender allows you to leave some chunky texture while still achieving overall creaminess. If you prefer a completely smooth soup, transfer it in batches to a regular blender, then return it to the pot. Be cautious when blending hot liquids to avoid splatters.
