▢8ounces fettuccine noodles, broken in half
▢1tablespoon unsalted butter, cut into small chunks

▢½cup freshly grated Parmesan cheese

Equipment

6-quart or larger Instant Pot (or other electric pressure cooker)
Tongs or a long spoon for stirring
Measuring cups and spoons
Grater for the Parmesan (if not pre-grated)

Preparation notes

Use freshly grated Parmesan for the best melting and flavor. Break the fettuccine noodles in half so they fit in the pot and submerge evenly. Heavy cream must be used as listed for the sauce texture — it won’t set up the same with substitutions.

Step-by-step instructions

Add the broth and aromatics: Pour 2 cups low-sodium chicken broth (or vegetable broth) into the Instant Pot. Sprinkle in 2 teaspoons minced garlic, ½ teaspoon kosher salt, and ½ teaspoon black pepper. Stir once to distribute the garlic and seasonings evenly through the liquid.
Layer the pasta: Break 8 ounces fettuccine noodles in half and arrange them in the pot. Try to fan the noodles slightly so they lie in an even layer and are mostly submerged in the broth. Do not stir the pasta into the liquid; you want it to sit in place to reduce sticking.
Add butter on top: Scatter 1 tablespoon unsalted butter, cut into small chunks, over the top of the fettuccine. The butter will melt during cooking and help create a slick surface for the noodles.
Seal and pressure cook: Close the Instant Pot lid and set the valve to sealing. Cook on Manual/High Pressure for 5 minutes. Because the noodles are broken in half and layered, 5 minutes gives tender, but not mushy, fettuccine.
Quick release the pressure: When the cook time ends, perform a quick release by carefully turning the pressure valve to venting. Once the steam has fully released and the float valve drops, open the lid away from your face.
Stir and add cream: Immediately stir the pasta to combine it with the cooking liquid. Pour in 1 cup heavy cream and mix thoroughly so the cream heats and begins to emulsify with the broth. Stir gently and make sure all the noodles are coated.
Melt in parmesan: Sprinkle ½ cup freshly grated Parmesan cheese over the pasta and stir until it melts into the sauce. If the mixture seems thin, let it sit in the still-warm pot for a minute or two while stirring occasionally — this helps the sauce thicken slightly.
Adjust seasoning and serve: Taste and adjust with a pinch more salt or pepper if needed. Serve immediately so the sauce is at its creamiest. Garnish with extra grated Parmesan or a sprinkle of freshly cracked black pepper, if you like.

Troubleshooting and tips

Sauce too thin: Let the pasta rest in the pot for 2–3 minutes while stirring occasionally to allow the sauce to thicken. Parmesan and the cooling cream will tighten up the sauce as it rests.
Pasta sticking together: Breaking the fettuccine in half and layering rather than stirring it into the broth helps prevent clumping. If you notice a few strands stuck, gently tease them apart with tongs after cooking.
Want more flavor: Use vegetable broth for a lighter flavor or chicken broth for a heartier base. A splash of white wine before pressure cooking (omit if avoiding alcohol) or a pinch of nutmeg added with the cream can deepen the sauce’s profile.
Reheating: Reheat gently on the stovetop over low heat with a splash of cream or broth to revive the sauce consistency. Stir continuously to avoid scorching.

Serving suggestions

This Instant Pot Fettuccine Alfredo is a fantastic base. Serve it with a crisp green salad and crusty bread to balance the richness. For a complete plate, top with sliced cooked chicken or sautéed mushrooms. If you add protein or vegetables, cook them separately and spoon over the finished pasta to keep the sauce silky.

Make-ahead and storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. The sauce will firm up when chilled; warm gently with a little cream or broth. This pasta can be made ahead and gently reheated for gatherings, but it’s best enjoyed fresh.
