What you will need
This recipe uses 5 simple ingredients that you can find at any grocery store:
- 2 cups pre-cooked spaghetti or angel hair
- 0.75 cup finely grated Pecorino Romano cheese
- 1.5 teaspoons coarsely ground black pepper
- 3 tablespoons water
- 1 tablespoon butter
Step by step instructions
Step 1: Heat the Pasta
Place the pre-cooked pasta and water in a large microwave-safe bowl. Microwave on high for 2 minutes until the pasta is hot and the water has mostly absorbed.
Step 2: Toast the Pepper
Push the pasta to one side and add the butter to the bowl. Microwave on high for 30 seconds until the butter melts, then stir in the black pepper and toss with the pasta.
Step 3: Add Cheese and Emulsify
Sprinkle the grated Pecorino Romano over the hot pasta in batches, tossing vigorously between each addition. Microwave for an additional 30 seconds if the cheese needs more help melting, then toss again until a creamy coating forms.
Step 4: Serve Immediately
Divide between two warmed bowls, finish with extra Pecorino and a crack of black pepper, and serve right away before the sauce tightens.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- Pecorino Romano → Parmesan cheese for a milder less salty sauce
- pre-cooked spaghetti → microwaveable rice noodles for a gluten-free version
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Adding the cheese to pasta that is too cool, which prevents it from melting properly and creates clumps
- Using too much water so the sauce becomes watery and fails to coat the pasta evenly
