I have all kinds of macaroni and cheese recipes on the blog, from a Crock-Pot version to green mac and cheese, and today I have a Creamy One Pot Macaroni and Cheese to add to the collection.

My other stove-top macaroni and cheese recipe is still a favorite, but I don’t always have canned milk. The difference is that this recipe makes a thick and sticky macaroni and cheese (it almost has the texture and taste of baked macaroni to me), while the other recipe has almost a runny sauce.

They are both excellent but different enough that I wanted to share both recipes.

How to Make One Pot Mac and Cheese

  1. Add milk, butter, and macaroni noodles to a large pot.
  2. Cook on medium, stirring often, until the noodles are cooked, about 15-18 minutes. 
  3. Add the cheese and salt, stirring until melted.
  4. Taste and adjust seasonings, adding more cheese if desired.

Recipe FAQs

What pasta is best for mac and cheese?

I prefer elbow macaroni, but bow tie, fusilli, and penne pasta also work well.

Can you use water instead of milk for mac and cheese?

You can use water instead, but your mac n cheese will be less creamy.

How do you fix runny mac and cheese?

If you end up having too much liquid in your macaroni and cheese, bring the contents back to a boil and cook until the desired consistency. Be sure to stir constantly to keep the milk and cheese from sticking to the bottom of the pot and burning.

Does mac and cheese make good leftovers?

This stuff in the blue box is not ideal for leftovers. The sauce gets powdery and has a weird texture. But this one-pot mac and cheese tastes SO good reheated. You still have the creamy factor, and the flavors have a chance to deepen. I recommend eating the leftovers within 1-2 days and storing them properly in the refrigerator.

Expert Tips

  • You don’t need to drain the pasta in this recipe. Cooking the pasta directly in the milk makes it extra creamy, and the sauce sticks to it much better.
  • To get the full creaminess factor, I recommend using whole milk or at least 2%
  • Use mild or sharp cheddar, adding more cheese if needed to achieve the true cheesy taste you’re looking for.

Creamy One Pot Macaroni and Cheese

This One Pot Macaroni and Cheese is so easy! Cook the macaroni right in the milk that's used to make the sauce. Creamy, delicious & ready in 15 minutes!
Prep: 5 minutes
Cook: 10 minutes
Total: 15 minutes
Servings: 4

Ingredients 

  • 2 1/2 cups whole or 2% milk

Instructions 

  • In a large pot add the milk, butter, and macaroni noodles. Turn the burner on medium and bring the mixture to a simmer, stirring often.
  • Reduce the heat if the milk seems to stick to the bottom of the pan and stir often until the noodles are cooked through, about 15-18 minutes. Slow and low is your friend here. If you cook this too fast and hot, the milk will curdle.
  • Stir in the cheese and salt until everything is melted.
  • Depending on the type and sharpness of cheese you may want to add up to another cup of cheese. Taste it and see. I used a moderately sharp cheddar and liked it at about 1 and 1/4 cups of cheese. If I had used something milder I think I would have used more.
  • Serve right away.

Notes

  • Don’t boil the noodles; just simmer them gently, or the milk will curdle, and your mac and cheese will have a gross texture. 
  • Whole milk is the best choice for creaminess, but 2% will also work.
  • I’ve made this a handful of times and each time I used a different amount of cheese, depending on my mood and how much cheese I have in the fridge. The milder the cheese, the more I think it needs to get a good cheese flavor.
  • If it has too much liquid, bring the contents back to a low boil and cook until the desired consistency, stirring constantly.

    I needed 4 c of milk and in the end it was still to dry/sticky. That said, Mac and cheese is comfort food. It was yummy.

    This is an excellent recipe. Props to Fotina, I just tried adding a tbsp to my gouda, cheddar, gruyere mix and it was truly a next level dish!

    Literally the best mac and cheese we’ve ever made. Made plenty in the past that took more work and more of a mess and didn’t taste as good as this simple recipe

    I love this recipe! I’ve made macaroni and cheese every way you can imagine. I always come back to this one. I’m not one to follow recipes, this one I do. It’s perfect, not mushy.
    Thank you for sharing it with us, Melissa!
