Introduction
Garlic Chilli Cacio e Pepe is a fiery, flavorful upgrade to the beloved Roman pasta classic. While traditional Cacio e Pepe relies on the magic of just pecorino romano, black pepper, and pasta water, this version introduces sautéed garlic and red chili flakes for an extra kick. The result? A rich, creamy sauce that coats each strand of pasta with the perfect balance of heat, sharp cheese, and aromatic spice—comforting yet bold in every bite.
The first time I made this, I was amazed at how just a few simple ingredients could create such depth of flavor. Toasting the pepper and chili flakes in butter and olive oil released a fragrant heat that infused the dish beautifully, while the creamy emulsion of pasta water and pecorino romano tied everything together. It was the kind of meal that felt both luxurious and effortless, ready in minutes but full of restaurant-worthy flavor.
What I love most about Garlic Chilli Cacio e Pepe is its versatility. You can control the heat level by adjusting the chili flakes, swap in parmesan for a milder cheese, or even add a squeeze of lemon for a bright twist. Pair it with a crisp white wine and a side of roasted vegetables or garlic bread for a complete meal. Whether you’re cooking for a quick weeknight dinner or impressing guests with minimal effort, this dish always delivers.

Step-by-Step Instructions
Cook the Pasta:
- Boil Water: Bring a large pot of salted water to a boil.
- Cook the Pasta: Add spaghetti and cook until just al dente (about 1-2 minutes less than package instructions).
- Reserve Pasta Water: Before draining, reserve 1 ½ cups of pasta water.
Prepare the Sauce:
- Toast the Black Pepper: In a large skillet over medium heat, toast the black pepper for 30 seconds until fragrant.

- Toss in the Pasta: Add the drained pasta to the skillet and toss to coat.
Emulsify the Sauce:
- Lower the Heat: Reduce to low heat before adding cheese to prevent clumping.
- Add the Pecorino: Gradually sprinkle in the pecorino while tossing continuously, allowing it to melt into a creamy sauce.
- Adjust Consistency: Add more pasta water if needed, stirring until the sauce is glossy and coats the pasta evenly.

Special Equipment
- Large Pot – Essential for boiling pasta with enough water to allow even cooking and proper starch release.
- Spider Strainer or Slotted Spoon – Helps transfer pasta directly to the sauce while retaining starchy water, which is key for emulsification.
- Microplane or Fine Grater – Ideal for grating Pecorino Romano finely so it melts smoothly into the sauce without clumping.
- Pepper Mill – Freshly ground black pepper is crucial for authentic flavor. A good mill allows you to control the grind size for maximum aroma.
- Mortar and Pestle – Perfect for crushing black peppercorns and red chili flakes to release their oils for a more intense, aromatic heat.
- Saucepan or Sauté Pan – A wide, shallow pan is best for tossing the pasta with cheese, pepper, and pasta water to create a creamy sauce.
- Fine Mesh Sieve – Useful for sifting grated cheese to remove clumps and ensure it incorporates smoothly into the sauce.
- Ladle – Helps scoop and control the amount of starchy pasta water added to the sauce for emulsification.
- Tongs – The best tool for tossing and evenly coating the pasta with the sauce while incorporating air for a silky texture.
- Infrared or Instant-Read Thermometer – Optional but helpful to ensure the cheese melts properly without overheating and clumping (ideally around 150–160°F (65–70°C)).
