4-6 servings
|
- 4 cups chicken broth, vegetable broth, or garlic broth (e.g., Garlic Better than Bouillon)
- 1 lb spaghetti
- 8 tbsp salted butter, divided into 1-tablespoon pats 1 stick
- 1 cup grated Pecorino Romano or Parmesan (or 1/2 cup of each) plus more for serving
- 1 tbsp cracked black pepper plus more to taste ( note: For best results freshly crack the pepper with a pepper mill
Ingredients
|
- Pour the broth into the Instant Pot, break the spaghetti over it and add to the broth, then follow with 4 tablespoons of the butter.
- Secure the lid and move the valve to the sealing position. Hit Manual or Pressure Cook on High Pressure for 8 minutes. Quick release when done. (NOTE: The pasta will appear soupy once the lid comes off. This is what we want because adding the dairy will thicken it up perfectly.)
- Stir in the remaining 4 tablespoons butter until melted, then add the cheese and stir until well combined. The sauce will thicken as soon as the cheese is absorbed, which is almost immediately.
- Add the cracked black pepper and give it a final stir. Add more pepper to taste.
- Transfer the pasta to bowls and top with more cheese and pepper, if desired.
Lighter comforts: Use ghee instead of butter.
JEFF’S TIP: If you want this to be a more traditional cacio e pepe, use water instead of broth and skip the butter. However, you will run the risk of the spaghetti clumping together when pressure cooked without the butter to keep it slick and independent.
If you want the sauce creamier (though less traditional in a cacio e pepe), add 1⁄2 cup heavy cream, half-and-half, or an unsweetened nondairy milk and an additional 1⁄4 cup cheese in Step 3.
Due to the heavy buttery/cheesy nature of this dish, it’s best eaten immediately and when freshly made.
Any leftovers stored in the fridge will dry out quickly due to the amount of butter and cheese absorbed by the pasta. So if reheating in the microwave or pot, add a little cream or any type of milk, then add a little more cheese after cooking and mix it up!
