Mac and Cheese Soup Recipe

I made a big pot of this mac and cheese soup on a chilly evening, and it was pure velvety comfort in a bowl. As soon as I stirred the sharp cheddar and Velveeta into the warm, garlic-infused broth, the rich cheese aroma instantly made my mouth water.

I love how the tender pasta shells catch the silky cheese sauce in every single spoonful. It has quickly become my go-to recipe when I want all the comforting goodness of baked macaroni in a cozy, sip-worthy soup.

Ingredients

Here are the simple ingredients you will need to build this ultra-creamy, comforting cheese soup in your kitchen.

• 2 cups Uncooked Small Pasta Shells – Small shells work best because their open shape scoops up the rich cheese broth with every bite.
• 4 tbsp Butter – Unsalted butter creates a rich base for sautéing the aromatic vegetables and forming the roux.
• 1 Celery Stalk (finely chopped) – Chop your celery small so it softens completely and adds subtle savory depth without large crunchy bits.
• 1 medium Yellow Onion (chopped) – Finely dice your onion so it cooks down evenly into the buttery soup base.
• 3 tbsp All-Purpose Flour – Whisked into the melted butter, flour acts as the essential thickening agent for a silky soup structure.
• 2 cups Chicken Broth – Low-sodium chicken or vegetable broth provides a flavorful liquid base that balances the rich dairy.
• 2 cups Milk – Use whole milk or half-and-half to give the soup a luscious, creamy body without becoming overly heavy.
• 8 oz Velveeta (cut into cubes) – Cutting Velveeta into small cubes ensures it melts smoothly without scorching or separating.
• 1 cup Shredded Cheddar Cheese – Grate your cheddar fresh from a block because pre-shredded cheese contains coatings that prevent smooth melting.
• 1 tsp Dry Mustard – Adds a subtle tangy bite that cuts through the rich cheese and enhances the natural cheddar flavor.
• 1 tsp Worcestershire Sauce – Delivers a splash of savory umami depth that elevates the overall flavor profile.
• ½ tsp Garlic Salt – Seasons the soup evenly while adding a punch of savory garlic goodness throughout.
• ¼ tsp Freshly Ground Black Pepper – Freshly cracked pepper adds a touch of sharp spice to balance the creamy dairy.
• ⅛ tsp Cayenne Pepper – A tiny pinch adds a gentle warmth that perks up the cheeses without making the soup spicy.

Note: Serves 6 people as a comforting starter or 4 people as a hearty main meal.

Equipment You Need

Having these basic kitchen tools ready makes assembling this rich, creamy soup quick and effortless.

• Dutch Oven or Large Pot: Provides plenty of room and even heat distribution for simmering the soup base smoothly.
• Medium Stockpot: Used to boil the pasta shells until perfect al dente texture before adding to the soup.
• Whisk: Essential for blending the flour into the butter and smoothly incorporating the liquids without lumps.

How to Make Mac and Cheese Soup?

Making this soup is a straightforward process of cooking your pasta, building a simple roux, and melting in the cheeses. The key to success is keeping the heat gentle so your cheese melts smoothly into the broth without separating. Follow these step-by-step instructions for a flawless bowl of soup.

Boil the Pasta

Bring a large pot of salted water to a rolling boil over high heat and add the pasta shells. Cook the shells according to package instructions just until al dente, usually about 1 or 2 minutes less than fully done. Drain the pasta immediately in a colander and set aside while you prepare the soup base. Keep in mind that the pasta will continue to soften slightly once added to the hot cheese soup later.

Sauté Vegetables and Make Roux

Melt the butter in your Dutch oven over medium heat, then add the finely chopped celery and onion. Cook the vegetables for 4 to 5 minutes, stirring occasionally until the celery softens and the onions turn translucent. Sprinkle the all-purpose flour directly over the cooked vegetables and stir constantly for 1 minute to cook out the raw flour taste. This roux step creates the thickening engine that gives the soup its velvety restaurant-quality body.

Whisk Liquids and Seasonings

Gradually pour in the chicken broth and milk while whisking constantly to prevent any flour lumps from forming. Bring the liquid mixture to a gentle simmer over medium heat until it begins to thicken slightly. Stir in the dry mustard, Worcestershire sauce, garlic salt, black pepper, and cayenne pepper until completely integrated. Reduce the heat to low so the milk mixture simmers gently without boiling over or scalding.

Melt Cheese and Combine

Add the cubed Velveeta to the simmering pot, stirring continuously until the cubes are completely melted and smooth. Remove the Dutch oven from the heat entirely before stirring in the fresh shredded cheddar cheese until silky. Gently fold in your cooked pasta shells until every piece is coated in the thick, glossy cheese soup. Taste the soup and adjust seasonings if needed, then ladle hot into bowls for serving.

Additional Tips for Making this Recipe Better

Through my own experience making this recipe, I have learned a few key tricks that ensure the absolute best results.

• I always cook my pasta shells separately and add them at the very end so they do not absorb all the broth and turn mushy.
• I recommend removing the pot from the heat before adding the shredded cheddar so the cheese melts smoothly without breaking.
• I like to grate my cheddar fresh off the block because pre-shredded cheese contains cellulose that makes soup grainy.
• I splash in an extra splash of warm milk right before serving if I prefer a thinner, more sip-able soup consistency.

Make Ahead and Storage

Proper storage and gentle reheating techniques keep this cheese soup rich and delicious for days.

Preparing Ahead

You can chop your celery and onions and shred your cheddar cheese up to two days in advance to speed up dinner prep. Store the prepped ingredients in separate airtight containers in the refrigerator until you are ready to start cooking.

Refrigeration and Restoring

Store leftover soup in an airtight container in your refrigerator where it will stay fresh for up to 3 to 4 days. As it cools, the pasta will absorb liquid and thicken the soup, so stir in a splash of milk or broth when restoring its texture.

Freezing Guidelines

Freezing dairy-based soups can cause the cheese sauce to separate and turn grainy upon thawing, so freezing is not recommended for this recipe. For best quality and texture, enjoy this soup fresh or stored in the refrigerator short-term.

Reheating Instructions

Reheat individual portions on the stove over low heat, stirring frequently and adding a splash of milk to restore creaminess. Avoid boiling the soup during reheating, as high heat can cause the cheese sauce to break and lose its smooth texture.
