With a twist on a classic Italian dish, this bucatini cacio e pepe recipe uses a key ingredient, cornstarch, to create a rich and silky sauce.
I love quick and easy pasta dishes - from garlic butter pasta to easy fettuccine alfredo to a weeknight bolognese to penne al baffo.
But the king of simple Italian pasta dishes is cacio e pepe. It literally means cheese and pepper. It typically is made with thick spaghetti and the sauce comes from combing Pecorino Romano, black pepper and pasta water.
If you really think about it, this is the original mac and cheese. But it relies on the pasta water with cornstarch instead of milk or cream to mix with the cheese to make smooth, cheesy sauce.
Why This Recipe Works
- It is a perfect weeknight meal as you can have ready in under 20 minutes.
- The combination of sharp cheeses and freshly cracked black pepper creates a creamy, savory and slightly spicy sauce that is deeply satisfying.
- By using cornstarch to thicken the sauce, it is a foolproof way to create the luxuriously creamy sauce while preventing clumping which can be an issue for other recipes.

Ingredients Notes
- Pasta - Bucatini is a thick cut pasta with a hole in the middle making it the perfect vehicle for the sauce. You can use other pastas like spaghetti.
- Cornstarch - The key ingredient which keeps the cheese sauce form clumping up when heated.
- Black pepper - Freshly cracked black pepper is key. Grinding it fresh releases its oils and enhances the flavor, giving the dish its signature spicy kick.
- Cheese - While not traditional, I like using the combination of Pecorino Romano and Parmesan to get a slightly tangy and nutty flavor. You can also use all of one or the other.
- Pasta water - Pasta releases some if its starches when boiling so it helps create a creamy dish when tossed with the cheese.
Variations
As with any dish, you can customize this to your preference. Some variations include:
- Pasta - While bucatini is my go-to, tonnarelli, spaghetti or even fettuccine all work.
- Protein - Shrimp, chicken or pancetta would all work great.
- Veggies - Asparagus, broccoli or peppers would complement the sauce well.
- Heat - A pinch of crushed red chili flakes would add some heat.
- Texture - Some toasted breadcrumbs or pine nuts can add great texture and flavor.

FAQs
I mentioned it above, but it is a Roman pasta dish that means "cheese and pepper. It usually comprises spaghetti, black pepper and Pecorino Romano.
Because of the Pecorino, you get a sharp, nutty flavor and a hot, biting flavor from the black pepper. I personally like to add Parmesan as well but it can be omitted.
Good thing is this recipe prevents the clumping issue because of the cornstarch.
Cornstarch helps emulsify the cheese and pasta water into a smooth and creamy sauce. It also helps to thicken the sauce and prevent it from becoming clumpy or separating.
The addition of cornstarch ensures that the sauce has a consistent texture and coats the pasta evenly, resulting in a delicious and creamy dish.
This cacio e pepe will last about 3 days if stored in an airtight container in the fridge.
My preferred method is placing the leftover pasta in a skillet with a splash of water. Cook on medium-low until heated through.
You can also microwave. Place in a microwave-proof bowl with a splash of water and microwave for 1 minute. Stir and microwave for another minute or until heated through.
Equipment
The equipment you use is important to how the recipe turns out. What is needed is the following:
- Kitchen scale - Helps get the precise amount of cheese needed.
- Cheese grater - I mentioned multiple time but use a cheese block and grate yourself.
- Food processor - Needed to blend the cheese paste together. A blender can be used too.
- Skillet/Dutch oven - You want something large enough to cook the sauce.
- Spoon - You want a good wooden spoon to stir everything together.
Pro Tips/Recipe Notes
- Make sure the water you are cooking the pasta in is salted as some of the flavor comes from it.
- Adding cornstarch to the cheese mixture helps emulsify the cheese and water, creating a smooth and creamy sauce.
- DO NOT overcook the pasta when boiling. You want it just al dente or slightly under. It continues to cook with the sauce.
- Toasting the black pepper enhances the flavor, but can be skipped if you want. Speaking of pepper, only use freshly ground.
- Don't use pre-shredded cheese. You want if finely grated so it melts well. Pre-shredded has added ingredients that will just make it clump up.
