What Is Cheddar Cheese Soup?

At its core, traditional American cheese soup is a rich, creamy, and savory dish built upon a classic culinary foundation: the roux. A roux is simply a mixture of fat (usually butter) and flour cooked together, which serves as the thickening agent. Once you whisk broth and milk into this base, you create a velvety liquid just waiting for handfuls of freshly grated cheese.

Unlike clear broths or chunky vegetable stews, cheese soup is all about luxurious texture and deep, savory dairy notes. It traces its American popularity back to the Midwest, specifically Wisconsin, where abundant local dairy production made cheese the star of many regional dishes. While it shares DNA with the beloved broccoli cheddar soup, a pure cheese soup allows the complex, sharp notes of the cheddar to stand alone, supported only by a subtle background of aromatic vegetables and spices.

Why You’ll Love This Recipe

You might be used to ordering this dish at your favorite bakery-café, but making it at home offers benefits that go far beyond saving a few dollars. Here is why this recipe will earn a permanent spot in your dinner rotation:

Incredible Texture: By shredding your own cheese and managing the heat correctly, you will achieve a silky-smooth consistency that canned or pre-packaged soups simply cannot match.
Customizable Base: This pure cheese soup acts as a fantastic blank canvas. You can easily fold in roasted broccoli, crispy bacon, or diced jalapeños depending on your mood.
Pantry Staples: Aside from picking up a high-quality block of cheese and perhaps some heavy cream, you likely already have the butter, flour, aromatics, and broth waiting in your kitchen.
Quick Cooking Time: Despite tasting like it simmered all day, this soup comes together on the stovetop in under 45 minutes, making it highly realistic for busy weeknights.

Ingredients

To achieve the best flavor and texture, the quality of your ingredients matters. Here is exactly what you will need for this recipe.

The Aromatics and Base

1/4 cup Unsalted Butter (1/2 stick): We start with butter to sauté the vegetables and build the roux. Unsalted butter allows you to perfectly control the sodium level of the final dish.
1 cup Yellow Onion, finely diced: Yellow onions offer a mild, slightly sweet background flavor that won’t overpower the cheese.
1/2 cup Carrots, very finely diced: Carrots add a touch of sweetness and a beautiful speckle of color.
1/2 cup Celery, very finely diced: Celery provides an earthy, aromatic backbone essential to all great soups.
2 cloves Garlic, minced: Fresh garlic enhances the savory depth.

The Thickeners and Liquids

1/4 cup All-Purpose Flour: This combines with the butter to thicken the soup.
2 cups Low-Sodium Chicken Broth (473 ml): Using low-sodium broth is critical because cheese is naturally salty. You can always add salt later, but you cannot take it out.
2 cups Whole Milk (473 ml): Whole milk provides the creamy body of the soup. Do not use skim milk, or the soup will be too thin and lack richness.
1/2 cup Heavy Cream (118 ml): A splash of heavy cream at the end adds that luxurious, restaurant-quality mouthfeel.

The Seasonings and Cheese

1 teaspoon Dry Mustard Powder: This is the secret ingredient. Mustard powder doesn’t make the soup taste like a hot dog; instead, it acts as a flavor enhancer that makes the cheese taste “cheesier.”
1/2 teaspoon Smoked Paprika: Adds a very subtle, warm smokiness that pairs beautifully with cheddar.
1/4 teaspoon freshly ground Black Pepper: Freshly ground provides the best flavor.
Salt to taste: Always taste your soup after the cheese is melted before adding any additional salt.
16 ounces Sharp Cheddar Cheese (450g), freshly grated off the block: The undeniable star of the show. Choose a high-quality sharp yellow cheddar for the best flavor and color.

How to Make Cheese Soup

The secret to a flawless cheese soup lies in the pacing. Take your time whisking, respect the heat levels, and do not rush the melting process.

Prep Time: 15 minutes Cook Time: 30 minutes Total Time: 45 minutes Servings: 6

Step 1: Sauté the Aromatics

Place a large heavy-bottomed pot or Dutch oven over medium heat. Add the unsalted butter and let it melt completely. Add the finely diced yellow onion, carrots, and celery. Sauté the vegetables for about 6 to 8 minutes, stirring occasionally, until the onions are translucent and the carrots have softened. Add the minced garlic and cook for 1 more minute until fragrant.

Step 2: Build the Roux

Sprinkle the all-purpose flour evenly over the sautéed vegetables. Stir continuously with a wooden spoon or silicone spatula for 2 full minutes. The flour will coat the vegetables and form a thick paste. This step is crucial as it cooks out the raw flour taste and lightly toasts the starches, preparing them to thicken your liquids.

Step 3: Incorporate the Liquids

Switch to a wire whisk. Slowly pour in the low-sodium chicken broth, about half a cup at a time, whisking vigorously after each addition. By adding the liquid slowly, you prevent lumps from forming. Once all the broth is incorporated and smooth, slowly whisk in the whole milk.

Step 4: Simmer and Thicken

Stir in the dry mustard powder, smoked paprika, and black pepper. Bring the soup to a gentle simmer over medium heat. Do not let it come to a hard, rolling boil, as high heat can scorch the milk on the bottom of the pot. Once simmering, reduce the heat to medium-low and let it cook uncovered for 10 to 15 minutes. Stir occasionally, scraping the bottom of the pot, until the soup has thickened enough to lightly coat the back of a spoon.

Step 5: Temper the Cream (Optional but Recommended)

Stir the heavy cream into the pot. Let it warm through for about 2 minutes.

Step 6: Melt the Cheese (The Crucial Step)

This is the most important step in the entire recipe. Turn off the stove and completely remove the pot from the heat source. Wait about 60 seconds to let the boiling action completely subside.

Grab a handful of your freshly grated sharp cheddar cheese and sprinkle it into the soup. Gently whisk in a figure-eight motion until that handful is completely melted and smooth. Repeat this process, adding the cheese one handful at a time, until all 16 ounces are incorporated.

Step 7: Final Seasoning

Taste the soup. Because cheese and broth vary in saltiness, this is the time to decide if you need a pinch of kosher salt. Ladle the hot soup into bowls and serve immediately.

Helpful Tips for the Best Results

Creating a smooth, creamy dairy soup requires a bit of culinary finesse. Follow these pro tips to ensure a perfect pot every time.

Never Use Pre-Shredded Cheese in Bags If you only take one piece of advice from this recipe, let it be this: grate your own cheese from a solid block. Pre-packaged shredded cheeses are tossed with anti-caking agents (like cellulose or potato starch) to keep them from clumping in the bag. These powders prevent the cheese from melting smoothly, resulting in a gritty, grainy soup. Take the extra five minutes to use a box grater.

Remove the Pot from the Heat Before Adding Cheese Cheese proteins are very delicate. If you dump cheese into a pot that is boiling over an active flame, the proteins will seize, tighten, and separate from the fat. This leaves you with a greasy, broken broth with rubbery clumps of cheese at the bottom. Always remove the pot from the heat and stir the cheese in slowly using residual heat.

Bring Dairy to Room Temperature If possible, measure out your milk and heavy cream and let them sit on the counter for 20 minutes before making the soup. Adding ice-cold milk into a hot roux can shock the mixture and create lumps.

Chop Vegetables Finely Because this is a creamy, luxurious soup, you don’t want giant, crunchy chunks of vegetables interrupting the texture. Take the time to dice your onions, carrots, and celery as finely and uniformly as possible. If you prefer a completely smooth soup without any vegetable texture, you can use an immersion blender to puree the base right before you add the cheese.

Variations and Substitutions

Once you have mastered this base recipe, you can easily tweak the ingredients to suit your cravings or dietary needs.

Classic Broccoli Cheddar: To make this a broccoli cheese soup, chop 2 cups of fresh broccoli florets into very small, bite-sized pieces. Add them to the pot at the same time you add the broth and milk. They will cook perfectly during the 15-minute simmering phase.
Wisconsin Beer Cheese Soup: For a pub-style twist, substitute 1 cup of the chicken broth with 1 cup of a light-colored beer, such as a pale ale or a pilsner. Avoid dark stouts or heavily hopped IPAs, as they will make the soup unpleasantly bitter.
Vegetarian Cheese Soup: Simply swap the chicken broth for a high-quality, low-sodium vegetable broth.
Spicy Jalapeño Cheddar: If you love a kick of heat, finely mince one or two fresh jalapeños (seeds removed for less heat) and sauté them with your onions and celery. Swap out half of the sharp cheddar for pepper jack cheese.
Gluten-Free Cheese Soup: To make this recipe gluten-free, substitute the all-purpose flour with a high-quality 1-to-1 gluten-free baking blend. Alternatively, you can skip the roux entirely, simmer the vegetables in broth, and thicken the soup at the end using a cornstarch slurry (2 tablespoons cornstarch mixed with 2 tablespoons cold water) before adding the dairy and cheese.

What to Serve With It

A rich bowl of cheese soup begs for the right accompaniments. Contrast and texture are your best friends here.

The Classic Bread Bowl: Hollow out a round loaf of sourdough or French bread and ladle the soup directly inside. The way the bread soaks up the creamy soup is unmatched.
Crusty French Baguette: Simple slices of warm, crusty bread smeared with a little garlic butter are perfect for dipping.
Soft Pretzels: Large, warm, salty soft pretzels are the ultimate pairing, especially if you opt for the beer cheese variation.
A Crisp, Acidic Salad: Because the soup is very heavy and rich, serve it alongside a bright salad. A mix of arugula, sliced green apples, candied walnuts, and a sharp lemon-dijon vinaigrette provides the perfect acidic contrast to cut through the dairy.
Garnishes: Top individual bowls with extra shredded cheese, chopped fresh chives, a dollop of sour cream, or crispy crumbled bacon.

Storage and Reheating

Dairy-based soups require a little bit of special care when it comes to storing and reheating to ensure they don’t break or curdle the next day.

How to Store: Allow the soup to cool until it is just warm, then transfer it to an airtight glass or plastic container. Store it in the refrigerator for up to 3 to 4 days. As it chills, the soup will become very thick, almost like a pudding. This is completely normal and expected due to the flour and cheese.

How to Reheat: The absolute best way to reheat cheese soup is on the stovetop. Transfer the chilled, thickened soup to a saucepan. Place it over medium-low heat. You may need to add a splash of milk or broth (about 1 to 2 tablespoons per bowl) to help loosen it up. Stir constantly and gently until it is warmed through. Do not let it boil.

If you must use the microwave, heat it in short 30-second bursts at 50% power, stirring well between each burst to distribute the heat evenly. Microwaving on high power will cause the cheese fats to separate and leave you with an oily soup.

Can You Freeze Cheese Soup? It is generally not recommended to freeze soups heavily reliant on dairy and cheese. When frozen and thawed, the milk proteins and fats separate, resulting in a grainy, unappetizing texture that is very difficult to bring back together. For the best quality, enjoy this soup fresh or from the refrigerator.

Frequently Asked Questions

Why did my cheese soup turn out grainy? Grainy soup is usually caused by one of two things: using pre-shredded bagged cheese that contains anti-caking agents, or boiling the soup after the cheese has been added. High heat causes the proteins in the cheese to seize and separate from the fat, resulting in a gritty texture. Always grate your own block cheese and turn off the heat before adding it.

What is the best cheese for cheese soup? Sharp yellow cheddar is the standard choice because it offers a robust, tangy flavor that can stand up to the broth and milk. Mild cheddar often lacks enough flavor punch and can get lost in the creamy base. You can also mix cheeses, such as combining sharp cheddar with a little bit of Gruyère or Fontina for extra meltability and nutty flavor.

Can I use half-and-half instead of milk and heavy cream? Yes. If you prefer to simplify the dairy ingredients, you can replace the 2 cups of whole milk and 1/2 cup of heavy cream with 2.5 cups of half-and-half. The result will still be wonderfully rich and creamy.

How do I fix a cheese soup that is too thin? If your soup hasn’t reached the desired thickness, do not just dump raw flour into the pot (it will clump instantly). Instead, create a slurry. Whisk 1 tablespoon of cornstarch with 1 tablespoon of cold water until smooth. Stir this into the simmering soup before you add the cheese, and let it cook for 2 minutes to thicken.

Can I make this soup ahead of time? Yes, cheese soup holds up very well in the refrigerator for a few days. Many people feel the flavors actually meld and improve on the second day. Just remember to reheat it very gently on the stove to maintain the silky texture.

Is dry mustard absolutely necessary? While you can skip it if you are in a pinch, dry mustard is highly recommended. It acts as an emulsifier and a flavor enhancer, bringing out the savory sharpness of the cheddar without making the soup taste like mustard. If you don’t have dry mustard powder, you can whisk in 1 teaspoon of classic Dijon mustard instead.
