Instant Microwave Macaroni and Cheese is a total game changer ~ this easy recipe makes a single serving ultra creamy mug of cheesy macaroni in just minutes, right in the microwave! This is the ultimate dorm room meal or after school snack.

Instant microwave mac & cheese is the answer to mid day cravings!
I tend to get crazy hunger spikes in the middle of the day, and for some reason I have a block against buying anything remotely appropriate for lunch when I’m at the supermarket. I’m always stuck roaming around the kitchen hunting for something, anything, to deal with my intense mid-day munchies, so imagine my excitement at finding an instant rich and creamy macaroni and cheese… for one… in a mug… made right in the microwave!

Macaroni and cheese for one is perfect if you live alone (or just happen to be alone and hungry)
No leftovers to tempt you into eating too much, or to go to waste! We tested this a whole bunch of times, and came to the conclusion that this recipe works best. Kids can do it themselves after school. or in a dorm. If you like macaroni and cheese, you’re going to want to give this a try, trust me. It may take a few tries to get it right for your mug and your microwave, but it will be worth it.

What you’ll need to make microwave macaroni and cheese
This is quick and easy, but because we’re dealing with a recipe for one, and a microwave, it is fairly precise, so listen up carefully — you’ll need just a few simple things to get started —
- a large mug
- a liquid measuring cup
- a 1/3 cup dry measuring cup
- elbow noodles
- some pre-shredded cheese
- a little milk
- and water.

Once you’ve got the recipe down, you can experiment with variations
But for the first time I suggest trying it as written. I found that store-bought finely shredded cheese worked best, and made the creamiest sauce. I used a cheddar/Monterey Jack blend, but other blends will also work. I used whole milk. My mug had a 1 2/3 cup (400 ml) capacity. My microwave is a fairly standard 1000 watts.

How to make microwave macaroni and cheese ~
- Put 1/3 cup of elbow noodles into your mug. Add a scant 1/2 cup of water to it. Be sure to use a liquid measuring cup to measure your water. And by scant, I mean just shy of 1/2 cup.
- Basically you will microwave this mixture until the water has evaporated. In my microwave this takes about 4 minutes.
- Microwave it for 2 minutes to start, then stir. Then another minute, and stir again. Then a final minute, and the water should be absorbed. If not, microwave a bit more until it is.
- Stir in your milk and cheese, and microwave for a final 30-60 seconds. Stir very well to blend everything together into a creamy sauce, and enjoy.

This might just be the best kitchen hack ever!

What kind of cheese to use for microwave macaroni and cheese?
- We tried this many different ways, and found that the pre-packaged grated cheese made the creamiest sauce. I was stumped about that until I read the ingredients and saw that there is some starch added to prevent clumping in pre-shredded cheese. I think this may also help thicken the sauce. Not sure, just a guess.
- We tried grating our own cheeses and the sauce came out thinner. In that case I added a pinch (1/8 teaspoon) of cornstarch to the milk, and that seemed to help with thickening.

I have eaten SO much mac & cheese in the past few days of testing that I am totally sick of it, so now it’s your turn — Let me know in the comments is you try this, and what worked and didn’t work for you!
Tips for making microwave macaroni and cheese ~
- Use a big mug. Mine had a 1 2/3 cup (400 ml) capacity.
- My microwave is a fairly standard 1000 watts. If yours is different you’ll have to tweak the timing.
- Use elbow pasta, anything larger will not cook quickly enough.
- Whole milk seems to work best, although feel free to use cream or half and half for a decadent treat.
- Measure carefully and accurately according to the recipe directions. Use a liquid measuring cup for the liquid, and a dry measuring cup for the solids.
- Cook your noodles until all of the water has all been absorbed. Check carefully after the 4 minutes, and if there is still any water left in your mug, keep microwaving in short bursts until it is absorbed. Microwaves, like ovens, can be finicky.
- Set your mug on a small plate to catch any water overflow.
- Pre-packaged finely shredded cheese made the creamiest thickest sauce. If you are grating your own cheese, you might experiment with adding a pinch of cornstarch to the milk and cheese.
- Stir well after adding the cheese and microwaving for the final 30-60 seconds. The sauce will develop and get creamy as you stir. It will continue to thicken as it sits. You can reheat it briefly if you like.
- If despite doing everything right you still end up with a thin sauce, you may have had extra water left in your pasta after the initial cooking, Check it carefully because water = watery sauce.
- Once you’ve got the basic operation down, experiment to your heart’s content with different cheeses, etc.

Sue, I’ve been trying to think of some different, easy, just-for-me lunches. And here you are with this! I can’t wait to try it! I just hope I don’t like it *too* much because it would be too easy to make it repeatedly!
I wish I had found this recipe when my son was a wee lad. This is a lot better than that boxed stuff with all the mystery ingredients. I get the munchies, too, so this would be something I’d like. I love mac ‘n cheese!
O MY GOODNESS!!!
My sons are going to love me even MORE for making them these cheesy-mugs!
Thank you so much!
This looks great, Sue! For some reason your blog stopped coming to my email so I signed up again!
Oh my word – what a perfect lunch! Your directions are detailed beautifully. Everyone should share this with college students and empty-nesters with traveling husbands – haha. Love the cheesiness – so beautiful! I have always wondered about making those single serve brownies in a mug – but thought I better not 🙂 Have a wonderful weekend!
something like this could definitely keep me from getting hangry, as i so often do. 🙂
Brilliant! Immediately sending this off to my daughter in college. She’s a mac and cheese freak and missing it terribly. I’m absolutely sure she’ll make good use of it!
I live alone, so this is a no brainer for me. I usually make mac & cheese, (with ham, and mini penne pasta) in a 3 cup pyrex casserole, (not easy to find that size). This makes two servings. I use 2 pre shredded cheese (s), and some grated parm, or ricotta (to replace 1 one shredded cheese), plus all of the basics for white sauce, which I make while I am cooking the pasta. After combining the sauce, penne, & ham, I top the whole thing with some buttered panko bread crumbs, cover it with foil and bake, at 350 degrees for about 35 minutes, then I take the foil off and keep it in the oven for 10 more minutes, so that the panko can get crispy. I let it stand for 15 minutes before I dive in. Very time consuming, but worth it. I am fortunate enough to be able to come for lunch, so I will definitely give this instant version a try. I really enjoy comfort food on a cold Winter day. Thanks again for such a quick and easy take on just about every one’s favorite!
This is so perfect for when you just need to satisfy a mac and cheese craving!
I’ve never tasted mac and cheese before. Shocking, I know 😀
