Ingredients For Instant Pot Chicken Alfredo

Chicken breast: The star of the dish, boneless, skinless chicken breasts are lean and cook quickly, making them a perfect choice for a speedy and healthy meal.
Italian seasoning: A blend of herbs like oregano, thyme, and basil, this seasoning adds a punch of flavor and brings a touch of Italian flair to the dish.
Water: Water is essential for cooking pasta properly. It ensures that the pasta is fully submerged and can expand as it cooks to a perfect al dente texture.
Fettuccine noodles: These are ideal for absorbing the rich and creamy alfredo sauce, and their broad and flat shape makes them a classic choice for this type of dish.
Olive oil: A bit of this heart-healthy oil is used to prevent sticking and add a subtle, fruity background flavor to the chicken as it cooks.
Alfredo Sauce: The creamy, garlicky sauce that coats the pasta and chicken with its rich, velvety texture can be conveniently bought or lovingly made from scratch with a few ingredients.

Substitutions and Variations

Change out the pasta sauce – Even though I use alfredo sauce, you can try other sauces and see what you think!
Add a little bit of cream cheese – This will add some creaminess to the mixture!
Change up the type of meat – While I love the flavor of this classic chicken alfredo, I also think that shrimp alfredo would taste awesome, too!

How To Make Instant Pot Chicken Alfredo

Pour ¾ cup water into the pot, add a steamer rack, and use the sauté function to boil.
Season the chicken breast evenly with Italian seasoning.
Once the water is boiling, place chicken breasts on the rack; stacking is fine.
Turn off sauté mode.
Add the pasta to a separate inner pot, drizzle with olive oil, cover with water to submerge the pasta, and then add an additional ¼ inch of water. Stir.
Put the pot with pasta over the chicken and cook on high pressure for 8 minutes.
After cooking, use the quick release method to vent.
Remove the pasta pot and stir in alfredo sauce.
Take out the chicken, chop it into chunks, and add to the pasta. Stir.
If desired, transfer to a baking dish and broil until the top is golden.

Expert Tips

Leftover Chicken: If you’re running really low on time, you can use leftovers of a rotisserie chicken to save on food waste!
Prevent Pasta Clumping: To prevent your fettuccine noodles from sticking together, add a tablespoon of butter to the pot along with the olive oil before cooking.
Enhance Flavor: To infuse the dish with a deeper garlic flavor, consider sautéing a few minced garlic cloves or add some garlic powder to the Instant Pot before adding the chicken.
For Thicker Sauce: If you prefer a thicker alfredo sauce, mix a teaspoon of cornstarch with a tablespoon of cold water and stir into the sauce after cooking.
Add Vegetables: After the pressure cooking is done, add steamed broccoli, sautéed mushrooms, or spinach to the mix to enhance its nutritional value and texture.
Adjust Creaminess: For an extra creamy texture, add a splash of heavy cream or half-and-half after stirring in the alfredo sauce.
A Touch of Freshness: To add color and freshness, garnish the top of the pasta with fresh parsley and grated Parmesan cheese before serving.

Alternative Cooking Methods

If you’re not in a rush, the slow cooker can be another fantastic method to make this delicious recipe. The process is simple: layer the seasoned chicken breasts at the bottom of the slow cooker, cover with water, and cook on low for about 3-4 hours.

Once the chicken is cooked through and tender, you can shred it or cut it into chunks. Then add the cooked fettuccine noodles and alfredo sauce, stirring well to combine. Cover and let it sit for an additional 25-30 minutes on the ‘keep warm’ setting to allow the flavors to meld.

This method is an excellent alternative to an Instant Pot and perfect for those days when you want to come home to a warm, ready-to-eat dinner.

Storing Tips

For best results, store the leftover chicken alfredo pasta in an airtight container and keep it in the fridge. You can reheat it in the microwave.

When it comes to storing leftover Chicken Alfredo, you can indeed freeze it for long-term preservation. Make sure to cool the pasta to room temperature before transferring it to a freezer-safe airtight container or heavy-duty freezer bag. Frozen Chicken Alfredo can last up to three months.

For reheating, transfer the thawed or frozen Chicken Alfredo to a microwave-safe dish and cover with a damp paper towel to keep the pasta moist. Microwave on medium power, stirring occasionally, until it’s heated through.

Alternatively, you can reheat it in a saucepan over a low to medium flame, adding a splash of milk or water to loosen the sauce, as it tends to thicken upon cooling. Remember to stir frequently to avoid burning and ensure even warming.

What To Serve With Instant Pot Chicken Alfredo

To complement Instant Pot Chicken Alfredo, consider serving it with sides that add a contrast to the dish’s richness. A crisp green salad dressed with a light vinaigrette provides a refreshing touch, while garlic bread or focaccia makes for a delightful way to soak up the creamy sauce.

For a vegetable side, roasted asparagus or green beans can add color and a touch of elegance to your meal. If you’re looking to bulk up the meal with something more substantial, a side of sautéed vegetables can be a good choice.
