Full Ingredients

Pasta Base

• 1/3 cup (40 g) small pasta (elbow macaroni, small shells, ditalini)
• 3/4 cup (180 ml) water
• 1/4 tsp kosher salt

Cheesy Sauce

• 1/2 cup (about 2 oz / 56 g) shredded sharp cheddar cheese
• 2 tbsp milk
• 1 tsp unsalted butter (optional, for richer flavor)
• 1 slice American cheese (optional, for a smoother melt)

Veggie Upgrade

• 1/2 cup frozen broccoli florets, chopped into bite-size pieces or 1/2 cup frozen peas
• 1 tbsp water (for steaming the vegetables)

Seasonings (Add to Taste)

• 1/8 tsp garlic powder
• 1/8 tsp ground mustard (optional, makes it taste more “mac-and-cheese”)
• 1/8 tsp black pepper, plus more to taste
• (Optional) Pinch of smoked paprika or cayenne for gentle heat

Step-by-Step Instructions

Step 1: Choose a big enough mug or bowl

Use a microwave-safe 16–20 oz mug or a deep cereal bowl. The pasta will bubble as it cooks, so giving it extra headspace helps prevent boil-overs. Keep a plate or paper towel handy to set under the mug if your microwave tends to bubble over.

Step 2: Microwave the pasta until tender

Add 1/3 cup pasta, 3/4 cup water, and 1/4 tsp kosher salt to the mug/bowl. Stir.

Microwave on HIGH for 4 minutes, then carefully remove and stir well. Continue microwaving on HIGH in 1-minute bursts, stirring each time, until the pasta is tender and most of the water is absorbed. Total cook time is typically 5–7 minutes depending on pasta shape and microwave power (this timing is written for an 1100W microwave).

Step 3: Drain (but not completely)

Carefully drain off excess water. For the creamiest result, leave about 1 tablespoon of hot starchy water in the mug. (That little bit helps the cheese melt into a smoother sauce.)

Step 4: Steam the broccoli or peas

In a small microwave-safe bowl, add 1/2 cup frozen broccoli (chopped) or 1/2 cup frozen peas plus 1 tablespoon water. Cover loosely (a lid slightly ajar or a plate works well).

Microwave on HIGH for 1–2 minutes until hot and bright green. Drain off any water.

Step 5: Make it cheesy and smooth

To the hot pasta, add 1/2 cup shredded cheddar, 2 tablespoons milk, 1 teaspoon butter (if using), and 1 slice American cheese (if using). Stir vigorously for 30–45 seconds until the cheese melts and the sauce looks glossy.

If the cheese looks stringy or tight, microwave for 10–15 seconds more, then stir again until smooth.

Step 6: Season and add the vegetables

Stir in 1/8 teaspoon garlic powder, 1/8 teaspoon black pepper, and 1/8 teaspoon ground mustard (if using). Taste and add a pinch more salt if needed.

Fold in the hot steamed broccoli or peas. If you want everything extra hot, microwave for a final 10–20 seconds.

Step 7: Finish and serve

Let it sit for 1 minute (the sauce thickens slightly as it cools). Give it one last stir and enjoy straight from the mug or bowl. Optional: top with a pinch of smoked paprika or chopped chives for a little extra flavor.

Pro Tips

• Avoid boil-overs: Use a larger mug/bowl than you think you need and stir every minute once it starts bubbling.
• Shred your own cheese if possible: Pre-shredded cheese has anti-caking agents that can make the sauce slightly grainy. It still works, but freshly shredded melts smoother.
• American cheese is a cheat code: One slice helps emulsify the sauce for a creamier, more stable melt.
• Adjust thickness easily: Too thick? Stir in 1–2 teaspoons more milk. Too thin? Microwave 10–15 seconds and stir to thicken.
• Salt after cheese: Cheese adds saltiness; always taste at the end before adding more.

Variations

• Spicy broccoli mac: Add 1/4 tsp hot sauce or a pinch of cayenne, and finish with black pepper.
• Protein boost: Stir in 1/4 cup cooked diced ham or 1/3 cup shredded rotisserie chicken after the cheese melts.
• Different cheeses: Swap half the cheddar with 2 tbsp grated Parmesan for sharper flavor, or use a mild cheddar plus American for the smoothest texture.

Storage & Make-Ahead

This mac & cheese is best eaten right away. If you have leftovers, cool and refrigerate in a covered container for up to 24 hours. Reheat in the microwave on HIGH in 20–30 second bursts, stirring each time, and add 1–2 tablespoons milk to loosen the sauce. For make-ahead, pre-measure the dry pasta and seasonings in a container; shred cheese in advance and keep refrigerated.
