Ingredients Needed to Make Mac and Cheese Soup
- 5 cups vegetable or chicken broth
- 1 cup (½ pound) elbow macaroni pasta, uncooked
- ⅓ cup unsalted butter
- ¼ cup all-purpose flour
- 1½ cups milk
- 2 cups sharp yellow cheddar cheese, grated

Step-by-Step Guide: How to Make Mac and Cheese Soup
Making Mac and Cheese Soup is surprisingly easy and satisfying, especially when you follow this clear step-by-step guide. Whether you’re a seasoned cook or just starting your comfort food journey, this process breaks down every move so you can confidently create a creamy, velvety soup your whole family will love.
Step 1: Boil the Pasta
Start by bringing 5 cups of broth—vegetable or chicken—to a gentle boil in a large pot. Once it’s bubbling, add your uncooked elbow macaroni. Stir occasionally so the noodles don’t stick to the bottom. Cook until they’re just al dente (firm to the bite), about 8–10 minutes. You don’t want them too soft because they’ll continue to cook in the soup later. Once done, drain and set the pasta aside, but don’t rinse—it helps the sauce cling better later.
Pro Tip: If you’re new to making pasta-based soups, check out our Chicken Orzo Tomato Soup Recipe for more pasta-in-broth cooking tips.
Step 2: Create a Smooth Roux
In a separate saucepan, melt ⅓ cup of unsalted butter over medium heat. When the butter begins to bubble slightly, whisk in ¼ cup of flour to create a roux—a thick paste that’s the secret to a creamy soup base. Whisk constantly for 1–2 minutes until it turns slightly golden and smells nutty. This step is key: it removes the raw flour taste and sets up your soup for that luscious, thick texture.
If you’ve never made a roux before, think of it as the heart of your soup—it’s what makes the cheese sauce smooth instead of grainy. For more roux-based dishes, peek at our Creamy Garlic Sauce Potatoes, which uses a similar technique.
Step 3: Slowly Add the Milk
Keeping your whisk moving, slowly pour in 1½ cups of milk. At first, the roux may clump up—don’t panic! Just keep whisking and adding milk a little at a time. The mixture will smooth out beautifully into a silky base. Once all the milk is incorporated, let it simmer for a few minutes until slightly thickened. You’re looking for a consistency that lightly coats the back of a spoon.
Step 4: Melt the Cheeses
Now for the magic. Reduce the heat to low and add your grated cheeses—2 cups of sharp cheddar, ⅓ cup Parmesan, and ¼ cup mozzarella. Stir constantly until the cheeses melt and blend together into a glossy, golden sauce. The aroma alone will make you want to dive in! Add the garlic powder and mustard powder at this stage. The garlic adds depth, while the mustard gives a gentle tang that enhances the cheese flavor.

Step 5: Combine Everything
Once your cheese sauce is smooth and dreamy, pour it gently into the pot with the cooked pasta and broth. Stir slowly to combine everything. The soup will instantly turn creamy, rich, and irresistible. If it feels too thick, add a little extra milk or broth until it reaches your desired consistency. Taste and adjust seasoning with salt and pepper if needed.
Step 6: Garnish and Serve
Ladle the hot Mac and Cheese Soup into bowls and sprinkle each serving with chopped green onions and freshly cracked black pepper. This adds a pop of color and a subtle freshness that balances the richness of the cheese.
For an extra cozy touch, serve it alongside crusty bread or even a small side of Honey Butter Skillet Corn. If you’re feeling fancy, top with a sprinkle of extra Parmesan or crumbled bacon.
Step 7: Step-by-Step Cleanup Tip
Don’t skip this bonus step-by-step tip—clean your saucepan right after you’re done. Cheese sauce can cling stubbornly to the pan as it cools. Simply fill it with warm soapy water and let it soak while you enjoy your meal. By the time dinner’s over, cleanup will be a breeze.
Final Step: Enjoy and Experiment
Now that you’ve mastered this step-by-step Mac and Cheese Soup recipe, make it your own! Try adding steamed broccoli, crispy ham bits, or even roasted red peppers for a twist.

What to Serve with Mac and Cheese Soup
Mac and Cheese Soup is rich and satisfying, so it pairs beautifully with something crisp or toasty. Try it with buttery garlic bread, a side salad, or even some roasted veggies. If you’re in a soup-and-sandwich mood, serve it alongside a simple grilled cheese or a turkey club. For another comforting side idea, check out Roasted Tomato Soup or Honey Butter Skillet Corn.
Key Tips for Making Mac and Cheese Soup
- Don’t overcook the pasta. You want it slightly firm since it’ll soften more in the soup.
- Use freshly shredded cheese. Pre-shredded cheese often has anti-caking agents that make your soup grainy.
- Adjust the thickness. If you prefer a creamier soup, add more milk; for a heartier texture, let it simmer a bit longer.
- Play with flavor. Add a pinch of smoked paprika or cayenne for a subtle kick—or stir in cooked bacon bits for something extra indulgent.
Storage and Reheating Tips for Mac and Cheese Soup
Let leftovers cool completely before transferring to an airtight container. Refrigerate for up to 3 days. To reheat, warm it slowly on the stove over low heat, stirring often. You can also microwave it in short bursts, stirring between each one. Avoid overheating or it’ll thicken too much. If that happens, add a splash of milk to bring it back to life. This soup doesn’t freeze well because of the cheese base—but honestly, you won’t have much left to freeze anyway.
FAQs
Can I use different cheese? Absolutely! Monterey Jack, Gruyère, or white cheddar all work beautifully.
Can I add protein? Yes! Toss in shredded chicken or crispy bacon for a heartier version.
Can I make it gluten-free? Substitute gluten-free pasta and flour—it still turns out deliciously creamy.
What if it’s too thick? Add a bit more broth or milk until you reach your perfect consistency.
