Creamy Mac and Cheese Without Flour

Most homemade mac and cheese starts with a roux, a mix of butter and flour cooked together to thicken the sauce. This one skips it. This mac and cheese without flour cooks the pasta right in milk and water. The starch from the pasta naturally thickens the liquid. Then you stir in cheese, and it melts into a smooth, silky sauce.

It takes about 20 minutes, uses one pot, and it's easy enough for beginners. It's also a great choice if you're out of flour or want a gluten-free version (with gluten-free pasta).

Why This Recipe Works

• Pasta starch thickens the sauce, so no flour is needed.
• A mix of milk and water gives enough liquid to cook the pasta and stay creamy.
• Adding cheese off the heat stops it from turning grainy or oily.
• A little mustard powder makes the cheese taste cheesier.
• Evaporated milk (optional) keeps the sauce extra smooth.

Ingredients

• 8 oz (225 g) elbow macaroni or small shells
• 2 cups (480 ml) whole milk
• 1 cup (240 ml) water
• ½ teaspoon salt
• 2 tablespoons butter
• ½ teaspoon mustard powder (or 1 teaspoon Dijon mustard)
• ¼ teaspoon garlic powder
• Pinch of paprika
• 2 cups (225 g) freshly shredded sharp cheddar
• ½ cup (55 g) shredded mozzarella or Monterey Jack (for stretch)
• ¼ cup (60 ml) evaporated milk or extra milk, as needed
• Black pepper

Why Shred Your Own Cheese?

Bagged shredded cheese is coated with powder (often starch or cellulose) to stop it sticking. That coating can make your sauce grainy. Shredding a block of cheese yourself takes 2 minutes and gives a much smoother sauce.

Best cheeses: Sharp cheddar for flavor, plus a melty cheese like mozzarella, Monterey Jack, Gouda or Colby for creaminess.

Step 1: Cook the Pasta in Milk

In a medium pot, add the milk, water and salt. Bring to a gentle simmer over medium heat. Watch it closely; milk can boil over fast.

Stir in the macaroni. Cook for 8–10 minutes, stirring often (every minute or so), until the pasta is tender and the liquid has thickened and mostly been absorbed.

Stirring is very important. Milk can stick and burn on the bottom of the pot.

Liquid gone but pasta still firm? Add a splash of water or milk and keep cooking.

Step 2: Add Butter and Seasoning

Lower the heat to low. Stir in the butter, mustard powder, garlic powder and paprika.

Step 3: Add the Cheese Off the Heat

Turn off the heat. Add the cheese one handful at a time, stirring gently until it melts before adding more.

Too much heat makes cheese separate and turn oily or stringy. The heat of the pasta is enough to melt it.

Step 4: Adjust the Texture

Stir in the evaporated milk (or more milk) a little at a time until the sauce is creamy and loose. Mac and cheese thickens as it sits, so make it a bit looser than you want.

Taste and add salt and black pepper. Serve right away.

Optional: Baked Crunchy Topping

Want a crispy top?

1. Heat the broiler.
2. Move the mac and cheese to an oven-safe dish.
3. Mix ½ cup panko breadcrumbs with 1 tablespoon melted butter and sprinkle on top with a little extra cheese.
4. Broil 2–3 minutes, until golden. Watch carefully.

Tips for the Creamiest Mac and Cheese

• Use whole milk. Low-fat milk makes a thinner sauce.
• Shred cheese from a block.
• Stir often while the pasta cooks.
• Add cheese off the heat, a little at a time.
• Serve right away. It's creamiest fresh.

Common Problems

Grainy sauce. The cheese got too hot, or bagged cheese was used. Keep the heat low and shred your own.

Oily or separated sauce. Overheated cheese. Stir in a splash of cold milk and stir gently to bring it back together.

Too thick. Stir in warm milk.

Too thin. Let it sit 2–3 minutes; it thickens quickly. Or add more cheese.

Burnt bottom. The heat was too high or it wasn't stirred. Use medium heat and stir often.

Variations

• Gluten-free: Use gluten-free pasta. Add a bit more milk, since some GF pasta absorbs more.
• Bacon mac: Stir in crumbled cooked bacon.
• Broccoli mac: Add small broccoli florets in the last 3 minutes of cooking.
• Spicy: Use pepper jack cheese and a pinch of cayenne.
• Extra protein: Add shredded cooked chicken or tuna.
• Smoky: Use smoked Gouda and smoked paprika.

Kid-Friendly Tips

Kids usually like milder cheese, so use medium cheddar and mozzarella. Small shell pasta holds more sauce in each bite. Add frozen peas for an easy vegetable.

Storage and Reheating

Fridge: Cool and refrigerate within 2 hours. Keeps 3–4 days in an airtight container.

Reheat: Add a splash of milk and warm on the stove over low heat, stirring, or microwave in 30-second bursts, stirring each time. Milk brings back the creamy texture.

Freezer: Possible for up to 2 months, but the sauce may get grainy. Reheat slowly with extra milk.

FAQs

Can you make mac and cheese without flour?

Yes. The starch from pasta cooked in milk thickens the sauce, so you don't need flour.

Why is my mac and cheese grainy?

The cheese got too hot, or you used pre-shredded cheese. Use low heat and shred from a block.

Can I use only water instead of milk?

Milk makes it creamy. Water alone gives a thinner, less rich sauce.

What is the best cheese for mac and cheese?

Sharp cheddar for flavor plus a melty cheese like mozzarella, Jack or Gouda.

Can I make it ahead?

It's best fresh. If making ahead, add extra milk when reheating.

Is this mac and cheese gluten-free?

It is if you use gluten-free pasta and check that your cheese and seasonings are gluten-free.
