Step-by-Step Instructions for Garlic Chilli Cacio e Pepe
Preparation Phase
- Gather all ingredients and equipment
- Take out all ingredients and place them on your counter
- Check that you have enough of everything before starting
- Place your large pot on one burner and skillet on another
- Get your cheese grater, measuring cups, knife, and cutting board ready
- Prepare the cheese
- Take out the block of Pecorino Romano cheese
- Using the fine side of your grater, grate 2 cups (200g) of cheese
- Place grated cheese in a bowl and let it come to room temperature while you prepare other ingredients
- BEGINNER TIP: Room temperature cheese melts more smoothly than cold cheese
- Prepare the black pepper
- Place whole peppercorns in a pepper mill or grinder
- Grind 2 tablespoons of black pepper into a small bowl
- BEGINNER TIP: If you only have pre-ground pepper, use 1½ tablespoons instead
- You want visible specks of pepper – this is a key flavor element of Garlic Chilli Cacio e Pepe!
- Prepare the garlic
- Peel 4 large garlic cloves
- Place a clove on your cutting board and hold it steady with your fingertips curled under (to protect them)
- Using a sharp knife, slice each clove as thinly as possible (aim for paper-thin slices)
- Place sliced garlic in a small bowl
- BEGINNER TIP: The thinner you slice the garlic, the more flavor it will release without becoming too harsh
- Measure remaining ingredients
- Measure 3 tablespoons olive oil into a small bowl or measuring cup
- Measure 1-2 teaspoons red pepper flakes into another small bowl
- Place 2 tablespoons salt near your pasta pot
- BEGINNER TIP: Having everything measured before cooking is called “mise en place” and makes the cooking process much smoother
Cooking Phase
- Boil the water
- Fill your large pot about ¾ full with cold water (about 4-5 quarts/liters)
- Place on high heat and bring to a rolling boil
- BEGINNER TIP: A rolling boil means large bubbles are constantly breaking the surface
- This will take 8-10 minutes, so you can prepare other things during this time
- Salt the water
- Once water is boiling, add 2 tablespoons salt
- CAUTION: Stand back when adding salt as water may bubble up aggressively
- Stir to dissolve salt
- BEGINNER TIP: Pasta water should taste salty like seawater – this seasons the pasta from within
- Cook the pasta
- Add 1 pound of pasta to the boiling water
- Stir immediately with tongs to prevent sticking
- Check the package directions for cooking time, then subtract 2 minutes (for al dente)
- Set a timer for this adjusted time
- Stir occasionally while pasta cooks
- BEGINNER TIP: “Al dente” means the pasta has a slight firmness when bitten – it will continue cooking in the sauce
- Prepare the water measuring cup
- While pasta cooks, place a heatproof measuring cup near the pasta pot
- You’ll use this to reserve pasta water before draining
- BEGINNER TIP: Pasta water is starchy and helps create a silky sauce without cream
- Make the garlic-chili oil
- While pasta is cooking, place your large skillet on another burner over medium heat
- Add 3 tablespoons olive oil and let it warm for 30 seconds
- Add sliced garlic and 1 teaspoon red pepper flakes (start with less if sensitive to heat)
- WATCH CAREFULLY: Stir constantly with a wooden spoon or heat-resistant spatula
- Cook for 2-3 minutes until garlic turns light golden (not brown or dark!)
- If garlic starts browning too quickly, immediately remove pan from heat
- BEGINNER TIP: Burnt garlic tastes bitter and will ruin your dish, so monitor closely
- Reserve pasta water
- When pasta is 1-2 minutes from being done, dip your measuring cup into the pot
- Carefully scoop out at least 2 cups of the starchy pasta water
- Set aside 1½ cups for the recipe and keep the extra in case you need more
- BEGINNER TIP: The starchy water is key to creating the creamy sauce without adding cream
- Create the sauce base
- Add 1 cup of the reserved hot pasta water to the skillet with garlic-chili oil
- Be careful as it may spatter when water hits oil
- Add 1½ tablespoons of your freshly cracked black pepper
- Stir to combine and bring to a gentle simmer
- Let simmer for 1-2 minutes to slightly reduce and infuse flavors
- BEGINNER TIP: This creates a flavor-infused base that will coat every strand of pasta
- Drain the pasta
- When your timer goes off, check pasta by taking one strand and biting it
- It should have slight resistance in the center (al dente)
- DON’T DUMP INTO A COLANDER – you’ll transfer pasta directly to sauce
- If pasta isn’t ready yet, continue testing every 30 seconds
- Combine pasta and sauce
- Using tongs, grab pasta directly from water and transfer to skillet with sauce
- BEGINNER TIP: It’s okay if some pasta water comes along with it
- Keep heat at medium-low
- Toss continuously using tongs, lifting and turning pasta to coat every strand
- Do this for 1-2 minutes until pasta absorbs some sauce and finishes cooking
- If mixture looks dry, add more pasta water, 2 tablespoons at a time
- Add the cheese – CRITICAL STEP
- IMPORTANT: Remove skillet from heat completely
- Wait 10 seconds to let the temperature drop slightly
- Sprinkle half the grated cheese (1 cup) over pasta
- Using tongs, toss vigorously until cheese melts and creates a creamy coating
- BEGINNER TIP: If you add cheese when the pan is too hot, it will clump instead of melt
- Gradually add remaining cheese while continuing to toss
- Keep tossing until all cheese is melted and sauce is smooth and creamy
- TROUBLESHOOTING: If sauce seems too thick, add more pasta water 1 tablespoon at a time
- If sauce seems too watery, add a bit more cheese and continue tossing
- Final adjustments
- Taste a strand of pasta
- If needed, add more black pepper, red pepper flakes, or a pinch of salt
- If cheese isn’t fully melted, return to very low heat for 30 seconds while tossing constantly
- The final sauce should cling to pasta without pooling in the bottom of the pan
- BEGINNER TIP: The sauce will thicken as it cools, so it’s better to have it slightly loose when serving
Serving Phase
- Plate immediately
- Garlic Chilli Cacio e Pepe is best served right away when the sauce is at its creamiest
- Warm your plates by running them under hot water and drying them (optional but recommended)
- Use tongs to create a nest of pasta on each plate by twirling in a circular motion
- Divide pasta equally among 4 plates
- BEGINNER TIP: Warmed plates keep the sauce creamy longer
- Finish the dish
- Sprinkle each plate with a little more freshly cracked black pepper
- Add a very small pinch of red pepper flakes on top for color and extra heat (optional)
- For an extra touch of richness, drizzle a tiny amount of high-quality olive oil on each plate
- Serve immediately
- BEGINNER TIP: Have forks ready and encourage everyone to eat while it’s hot!
Troubleshooting Your Garlic Chilli Cacio e Pepe
Cheese Clumping
- Problem: Cheese forms into sticky clumps instead of smooth sauce
- Fix: Remove pan from heat before adding cheese and make sure pasta water is still hot but not boiling
- Prevention: Always take the pan off heat before adding cheese and add cheese in small batches while tossing constantly
Sauce Too Thin
- Problem: Sauce isn’t clinging to pasta
- Fix: Add more cheese and continue tossing over low heat
- Prevention: Don’t add too much pasta water at once; add in small increments
Sauce Too Thick
- Problem: Sauce is gummy or sticky
- Fix: Add more hot pasta water, 1 tablespoon at a time, while tossing
- Prevention: Keep extra pasta water handy and don’t let the pasta sit too long before serving
Garlic Burning
- Problem: Garlic turns dark brown or black
- Fix: Lower heat immediately and start over if severely burnt (bitter taste will ruin dish)
- Prevention: Use medium-low heat and stir constantly while garlic cooks
Pasta Too Soft
- Problem: Pasta is mushy instead of al dente
- Fix: Unfortunately, this can’t be fixed once it happens
- Prevention: Set a timer and cook pasta 2 minutes less than package instructions
