Why You’ll Love This Recipe

  • One-Pot Wonder: Everything cooks in the Instant Pot, meaning fewer dishes to wash and less cleanup time.
  • Quick and Efficient: From prep to table in about 40 minutes, making it perfect for those hectic weeknights when you want something delicious but don’t have hours to spend in the kitchen.
  • Foolproof Results: The pressure cooking method ensures perfectly cooked pasta and juicy chicken every single time.
  • Restaurant Quality at Home: This tastes just like (or dare I say better than) what you’d order at your favorite Italian restaurant, but at a fraction of the cost.

Ingredients You’ll Need

  • Chicken breasts: Creates the protein foundation of this dish. Slice them thinly for quicker, more even cooking.
  • Seasonings (garlic powder, onion powder, salt, pepper): These build a flavorful base for the chicken that complements the creamy sauce perfectly.
  • Olive oil: Helps brown the chicken and prevents it from sticking to the pot.
  • Chicken broth: Adds depth of flavor to the pasta as it cooks and creates steam for pressure cooking.
  • Water: Works with the broth to create enough liquid for cooking the pasta properly under pressure.
  • Fettuccine pasta: The traditional choice for alfredo sauce. Breaking it in half helps it fit in the Instant Pot and cook evenly.
  • Heavy cream: The key to that luxurious, velvety sauce texture we all crave in alfredo.
  • Parmesan cheese: Brings the nutty, salty flavor that defines a good alfredo sauce. Use freshly grated for the best melting and flavor.
  • Fresh garlic: Adds a punch of aromatic flavor to the sauce that dried garlic just can’t match.
  • Fresh parsley: Adds a pop of color and fresh flavor that cuts through the richness of the sauce.

Variations

Protein Swaps

Substitute the chicken with shrimp (add after pressure cooking), sliced Italian sausage, or even cubed salmon for different flavor profiles.

Veggie Additions

Stir in steamed broccoli, sautéed mushrooms, or fresh spinach at the end for added nutrition and texture.

Cheese Options

Try mixing in some Romano or Asiago cheese with the Parmesan for a more complex flavor profile.

Cajun Kick

Season your chicken with Cajun spice blend instead of the garlic and onion powders for a spicy twist that’s absolutely addictive.

How to Make Instant Pot Chicken Alfredo

Step 1: Season and Brown the Chicken

Season chicken breasts with garlic powder, onion powder, half the salt, and pepper. Set the Instant Pot to Sauté mode and add olive oil. Once hot, brown the chicken pieces on both sides until golden (about 2-3 minutes per side). Work in batches if needed to avoid overcrowding.

Step 2: Prepare the Pasta Base

Remove the browned chicken to a plate. Pour chicken broth and water into the pot, scraping the bottom to release any browned bits (this prevents the dreaded “burn” notice). Add the remaining salt, then break the fettuccine in half and add to the liquid, ensuring all pasta is submerged.

Step 3: Pressure Cook

Place the browned chicken on top of the pasta. Cancel the Sauté function, then set to Manual/Pressure Cook for 6 minutes. Make sure the valve is set to sealing position.

Step 4: Quick Release and Finish

When cooking completes, perform a quick release of pressure. Remove the chicken to a cutting board and slice it. Add heavy cream, Parmesan cheese, and freshly grated garlic to the pasta in the pot, stirring well to combine.

Step 5: Thicken and Serve

Let the pasta mixture sit for a few minutes – it will continue to absorb liquid and thicken. Arrange the sliced chicken over portions of pasta and garnish with additional Parmesan and fresh parsley.

Pro Tips for Making the Recipe

  • Brown in Batches: Don’t crowd the chicken when browning – work in batches for the best caramelization.
  • Scrape the Bottom: After adding the broth, be sure to deglaze the pot by scraping up any browned bits to prevent the burn warning.
  • Al Dente Perfection: The 6-minute cook time is designed for al dente pasta. If you prefer softer pasta, add an extra minute.
  • Grate Your Own Cheese: Pre-grated cheese often contains anti-caking agents that can make your sauce grainy. Freshly grated melts much better.
  • Let It Rest: Allow the pasta to rest for a few minutes after adding the cream and cheese – the sauce will thicken beautifully as it sits.

How to Serve

Perfect Pairings

Serve this rich pasta dish with a crisp green salad dressed with a light vinaigrette to balance the creaminess of the alfredo.

Bread Options

Garlic bread or a crusty Italian loaf makes the perfect companion for soaking up extra sauce.

Wine Suggestion

A light Pinot Grigio or unoaked Chardonnay pairs beautifully with the creamy sauce without overwhelming the dish.

Make Ahead and Storage

Storing Leftovers

Store any leftover chicken alfredo in an airtight container in the refrigerator for up to 3 days. The sauce will thicken considerably when cold.

Reheating

When reheating, add a splash of milk or cream to loosen the sauce. Warm gently on the stovetop over medium-low heat, stirring frequently to prevent scorching. Alternatively, microwave in 30-second intervals, stirring between each until heated through.

Freezing

While cream-based sauces typically don’t freeze well, you can freeze this dish in a pinch. Thaw overnight in the refrigerator and expect to add extra cream when reheating to restore the sauce’s consistency.

FAQs

  1. Can I use frozen chicken breasts for this recipe?

    Yes, but you’ll need to adjust the cooking method slightly. Skip the browning step and increase the pressure cooking time to 8 minutes. The texture won’t be quite the same, but it will still be delicious. Just make sure the chicken reaches 165°F before serving.

  2. What if I don’t have fettuccine?

    Other pasta shapes work wonderfully! Linguine or pappardelle are closest in shape to fettuccine. For shorter pastas like penne or bow ties, you may need to adjust the cooking time slightly (typically a minute less for smaller shapes).

  3. Why did my sauce come out too thin?

    This typically happens if you release the pressure too soon after cooking. Let the pasta sit for 5-10 minutes after adding the cream and cheese – it will continue to absorb liquid and thicken. If it’s still too thin, you can set the Instant Pot to Sauté mode for a minute or two, stirring constantly.

  4. Can I make this dish lighter?

    You can substitute half-and-half for the heavy cream, though the sauce won’t be quite as rich. Another option is using evaporated milk with a tablespoon of cornstarch mixed in to help thicken the sauce. For the cheese, stick with real Parmesan, but you can use a bit less.

Final Thoughts

This Instant Pot Chicken Alfredo brings together convenience and indulgence in one magnificent dish. Whether you’re cooking for a family dinner or looking to impress guests without spending hours in the kitchen, this recipe delivers restaurant-quality results with minimal effort.

  • 1/8 teaspoon ground black pepper
  • 2 tablespoons olive oil

For the Pasta:

  • 1 cup low-sodium chicken broth
  • 3 1/2 cups water
  • 1 pound dry fettuccine pasta, broken in half

For the Alfredo Sauce:

  • 1 cup heavy cream
  • 1/2 cup freshly grated Parmesan cheese (plus more for serving)
  • 2 cloves garlic, grated

Optional Garnish:

  • Chopped fresh parsley

Instructions

  1. Season the Chicken
    Season the chicken breasts with garlic powder, onion powder, ½ teaspoon kosher salt, and ground black pepper. Ensure the chicken is evenly coated for flavor.
  2. Brown the Chicken
    Add olive oil to the Instant Pot and press the Sauté button. Once the oil is heated, place the chicken breasts in the pot. Cook for a few minutes on each side until browned. If needed, do this in batches and add more oil if necessary. Remove the chicken from the pot and set it aside on a plate.
  3. Prepare Pasta Base
    Add the chicken broth, water, and the remaining ½ teaspoon of salt to the Instant Pot. Break the fettuccine pasta noodles in half and add them to the pot, stirring to fully submerge the noodles in the liquid. Place the browned chicken back on top of the pasta.
  4. Pressure Cook
    Press the Cancel button, then select the Manual or Pressure Cook function, and set it for 6 minutes. When the cooking time is complete, carefully perform a quick release to immediately release the steam.
  5. Slice the Chicken
    Remove the cooked chicken breasts from the pot and place them on a cutting board. Let them rest for a moment before slicing into strips.
  6. Make the Alfredo Sauce
    Pour the heavy cream, Parmesan cheese, and grated garlic into the Instant Pot with the cooked pasta. Stir everything together to create a creamy sauce. Allow the pasta to sit for a few minutes to absorb any excess liquid.
  7. Serve
    Plate the Alfredo pasta, top with the sliced chicken breast, and sprinkle with additional grated Parmesan cheese and chopped fresh parsley, if desired. Serve immediately and enjoy!

Notes

  • Add Cajun seasoning to the chicken for a spicier, Cajun-inspired twist on this classic Alfredo.
