As a nutritionist, I’m always excited about recipes that make portions simple without taking the joy out of eating. Here, you get one satisfying serving, and you can choose the pasta that works best for you. Classic elbows deliver that nostalgic mac-and-cheese experience, while rotini catches plenty of gooey cheddar in its spirals. For extra protein and fiber, choose whole grain or a pasta that’s made with legumes (like chickpeas, lentils, edamame, etc).

I first played around with this idea on one of those nonstop afternoons when lunch somehow kept getting pushed further down the schedule. I didn’t want to boil a pot of water or deal with cleanup, so I grabbed the biggest mug in my cabinet and let the microwave take over. A few minutes later, I was stirring cheddar into piping-hot pasta and feeling very excited about my tiny culinary shortcut. It’s amazing how much happiness can fit into one mug, haha.

Why this little mug is mighty

  • Comfort in minutes: You’re just a quick microwave session away from a warm mugful of cheesy goodness.
  • Just 3 ingredients: Pasta, water, and cheddar are all you need (plus a little Parm if you’re like me!).
  • One perfectly portioned serving: There’s no need to cook an entire box when you’re feeding yourself or squashing a sudden craving.
  • Choose your favorite noodle: Small elbows, rotini, and chickpea pasta can all work with slight timing adjustments.
  • Cleanup stays contained: The pasta cooks and the cheese melts in the same oversized mug.

The mug size matters

Be sure to use an extra-large 20-ounce microwave-safe mug. The water will bubble up and overflow as the pasta cooks, so always place the mug on a microwave-safe plate or inside a large bowl. That way, the excess water lands neatly underneath instead of turning your microwave into a splash zone. The bubbling is part of the process… no need to panic!

Microwave strengths and pasta shapes can vary, so taste a noodle after the initial cooking time. When it has reached your preferred tenderness, stir in the cheddar immediately while everything is still very hot. The residual heat melts the cheese into a smooth, creamy coating. Add a little Parmesan for an extra cheesy finish, then grab a fork and dig in straight from the mug!

Ingredients
 

  • ½ cup small elbow macaroni or rotini/chickpea pasta*
  • ½ cup water
  • ½ cup shredded cheddar cheese
  • Optional 1 to 2 teaspoons parmesan cheese
Ingredient Details to Know
*Rotini – after 3 ½ minutes in microwave, carefully remove mug, add an additional tablespoon of water, stir, and microwave for another 1 minute.
*Banza Elbows – after 3 ½ minutes in microwave, carefully remove mug, add an additional tablespoon of water, stir, and microwave for 30 more seconds. 
 

Instructions
 

  • Mist the inside of an extra-large (20oz) mug with oil spray. Add the pasta and water. Place the mug on a microwave-safe plate or inside a large mixing bowl (this is important because there will be water overflow as the pasta cooks and this ensures the water will neatly spill onto the plate or bowl versus making a mess in the microwave)—and microwave for 3 ½ to 4 minutes.
  • Carefully remove the mug, test a piece of pasta and if it’s too al dente for your liking, stir it up and place the mug back in the microwave for another 30 seconds or so.
  • Immediately add in the cheese (while the pasta is still very hot) and mix until it becomes all melty and gooey. Enjoy!
