There’s something undeniably comforting about macaroni and cheese—but when you take all that cheesy goodness and turn it into a velvety, spoonable soup? It’s a whole new level of cozy. I remember the first time I made this Creamy Mac and Cheese Soup on a rainy evening, curled up with a big bowl and a slice of crusty bread on the side. It was the food hug I didn’t know I needed.

This dish blends the nostalgic flavors of traditional mac and cheese with the soul-soothing warmth of a soup. It’s rich without being heavy, silky with just the right touch of cream, and bursting with cheesy flavor. Whether you’re feeding picky eaters or looking for something quick and satisfying, this recipe checks every box.

What Type of Cheese Works Best in Creamy Mac and Cheese Soup?

When it comes to this soup, the cheese is the star—and not just any cheese will do. I’ve tested quite a few combinations, and I always come back to sharp cheddar for that bold, classic flavor. It melts beautifully and gives the soup that signature mac-and-cheese color and richness.

For added creaminess, a small amount of cream cheese or Velveeta can take the texture up a notch without overpowering the dish. Gruyère, gouda, or Monterey Jack are also excellent for layering in more flavor if you’re feeling fancy. Whatever you choose, make sure it’s good quality and melts smoothly—you want luscious ribbons of cheese, not grainy bits.

Options for Substitutions

One of the beauties of this soup is how flexible it can be:

Milk: You can use whole milk for richness, but 2% works fine. For a dairy-free version, try unsweetened oat milk or cashew milk—they have the creamiest consistency.
Cheese: As mentioned, cheddar is king, but don’t be afraid to mix in mozzarella for stretch or parmesan for a salty, nutty depth.
Pasta: Elbow macaroni is classic, but small shells, ditalini, or even orzo can work. Just keep the pasta size small to maintain that spoon-friendly texture.
Flour/Butter Roux: If you’re gluten-free, use a 1:1 GF flour blend to make the roux. It works just as well to thicken the soup.
Broth: Chicken broth adds depth, but vegetable broth keeps it vegetarian without sacrificing flavor.

Ingredients for This Creamy Mac and Cheese Soup

Each ingredient in this soup serves a specific role in creating that creamy, cheesy magic. Here’s what you’ll need and why it matters:

Elbow Macaroni: The classic pasta choice—its shape holds onto the cheesy soup, giving you perfect bites every time.
Butter: Used to start the roux, butter adds a rich base flavor and helps the soup develop that luscious, thick texture.
All-Purpose Flour: This is the thickening agent. Combined with butter, it creates a roux that sets the foundation for a creamy soup.
Milk: The liquid base that makes the soup velvety. Whole milk is best for richness, but you can substitute it as needed.
Chicken or Vegetable Broth: Adds a savory depth that balances the richness of the cheese and cream.
Sharp Cheddar Cheese: The star ingredient. It delivers bold flavor and smooth meltability that defines the whole dish.
Parmesan Cheese: Offers a salty, umami punch and helps enhance the complexity of the cheese flavor.
Cream Cheese (optional): For that extra touch of silkiness and body in the soup—especially useful if you like it ultra creamy.
Salt and Black Pepper: Essential for seasoning and balancing out the cheesy richness.
Ground Mustard (optional): Adds a subtle tang that enhances the cheese without making the soup taste mustardy.
Garlic Powder or Onion Powder (optional): For added depth if you want a flavor boost with minimal effort.
Fresh Parsley (for garnish): Adds a pop of color and a fresh note to each bowl.

Step 1: Cook the Pasta

Start by boiling your elbow macaroni in salted water until just al dente—firm to the bite. Drain and set aside. Don’t overcook the pasta since it’ll continue to soften in the soup.

Step 2: Make the Roux

In a large pot or Dutch oven, melt the butter over medium heat. Once fully melted and bubbling slightly, whisk in the flour to form a smooth roux. Cook this mixture for 1-2 minutes to eliminate any raw flour taste. This is the foundation of your creamy texture.

Step 3: Add Milk and Broth

Slowly pour in the milk and broth, whisking constantly to keep things smooth. This will gradually thicken into a velvety soup base. Let it simmer gently (not boil) for about 5–7 minutes, stirring often to avoid any clumps or scorching at the bottom.

Step 4: Stir in the Cheese

Reduce the heat to low and add the shredded cheddar, parmesan, and cream cheese (if using). Stir until all the cheese is fully melted and the soup is luxuriously creamy. Season with salt, pepper, and any optional spices like ground mustard or garlic powder at this stage.

Step 5: Add the Pasta

Fold the cooked macaroni into the cheese soup, stirring gently to coat all the pasta without breaking it apart. Let everything simmer together for just a couple more minutes so the flavors can meld.

Step 6: Final Touches

Give it a taste and adjust the seasoning if needed. If the soup seems too thick, you can loosen it with a splash more broth or milk. Ladle into bowls, sprinkle with more cheese or fresh parsley, and serve hot.

How Long to Cook the Creamy Mac and Cheese Soup

This recipe is weeknight-friendly and doesn’t take long at all. Here’s the breakdown:

Pasta Cooking: 7–8 minutes (until al dente)
Roux and Liquid Base: 10 minutes
Cheese Melting & Final Simmer: 5–7 minutes
Total Time: Around 25–30 minutes from start to finish

The key is not to overcook once the cheese is added. Keep the heat low during the final stage to prevent the cheese from separating and becoming grainy.

Tips for Perfect Creamy Mac and Cheese Soup

Shred Your Own Cheese: Pre-shredded cheese has anti-caking agents that can prevent smooth melting. Block cheese always wins for creaminess.
Low Heat for Cheese: After adding the cheese, keep the heat low to avoid curdling or gritty texture.
Season Gradually: Cheese is salty, and broths can vary. Always taste before adding more salt.
Roux Patience: Don’t rush the roux. Cooking it for at least 1-2 minutes before adding liquids ensures your soup won’t taste floury.
Balance the Thickness: If the soup thickens too much as it sits, add a splash of milk or broth to loosen it up.
Use Al Dente Pasta: Slightly undercooked pasta will finish perfectly in the soup without becoming mushy.
Avoid Boiling Post-Cheese: Once the cheese goes in, no boiling! Just a gentle simmer is all you need.
Serve Immediately: It’s best enjoyed fresh when the cheese is at its silkiest and the texture is at its prime.

Watch Out for These Mistakes While Cooking

Even a comforting soup like this one can go sideways if you’re not careful. Here are the most common missteps and how to steer clear of them:

Boiling After Adding Cheese: This can cause the cheese to split and become grainy. Keep the heat gentle once the cheese is in the pot.
Using Pre-Shredded Cheese: It contains additives that prevent smooth melting, which can affect both taste and texture.
Overcooking the Pasta: Remember, it continues cooking in the soup. Aim for al dente when boiling.
Skipping the Roux Step: Without properly cooking the flour and butter, you risk ending up with a thin or gritty soup.
Too Much Pasta: Don’t overload the soup with macaroni—it should be brothy enough to eat with a spoon.
Adding Cold Milk All at Once: This can cause the roux to seize up. Warm the milk slightly or add it in slowly while whisking.
Not Seasoning in Layers: Build flavor as you go—season the roux, then the broth, then after cheese is added.
Letting It Sit Too Long Before Serving: The soup thickens as it sits. Serve right away or keep it gently warmed if needed.

What to Serve With Creamy Mac and Cheese Soup?

A rich soup like this pairs wonderfully with something crisp, tangy, or fresh to balance it out. Here are 8 delicious options:

1. Garlic Bread

Buttery, crisp, and perfect for dipping into every cheesy spoonful.

2. Roasted Broccoli

Adds some green to the plate and a nice smoky edge to contrast the creaminess.

3. Caesar Salad

Crunchy romaine, sharp parmesan, and that classic tangy dressing—it’s a great match.

4. Grilled Cheese Sandwich

Because more cheese is never a bad idea. Especially with tomato or bacon.

5. Apple Walnut Salad

Sweet, tart, and nutty—it brings freshness and texture to the table.

6. Crispy Bacon Bits

Sprinkle on top for a salty, smoky crunch. Or serve on the side for add-as-you-go.

7. Pickled Vegetables

Their acidity cuts through the richness and cleanses the palate.

8. Spicy Roasted Chickpeas

For a crunchy, protein-packed topping or snack to go with the soup.

Storage Instructions

Creamy Mac and Cheese Soup stores quite well, but there are a few things to keep in mind to maintain its texture and flavor:

Refrigeration: Store leftovers in an airtight container in the fridge for up to 3–4 days. The soup will thicken as it cools, so you may want to add a splash of milk or broth when reheating to bring it back to a silky consistency.
Reheating: Warm gently over low heat on the stovetop or in the microwave in short intervals, stirring in between. Avoid boiling to prevent the cheese from separating.
Freezing: Not recommended. The dairy and pasta don’t freeze well and can become grainy or mushy when thawed. If you must freeze it, do so before adding the pasta, and add freshly cooked pasta when reheating.
