Instant Pot Chicken Alfredo: a simple, family-friendly dinner made with fettuccine, chicken, and creamy Alfredo sauce cooked entirely in a pressure cooker. Ready in minutes—perfect for busy weeknights.
If you own an Instant Pot (or other electric pressure cooker), this Instant Pot Chicken Alfredo is a must-try. There’s no need to pre-cook the pasta or chicken—just combine the ingredients in the pot, pressure cook, and dinner is done. It’s an easy, comforting meal that comes together with minimal effort.
This version uses a store-bought jar of Alfredo sauce for convenience, though you can experiment with homemade sauce if you prefer. I tested the straightforward “dump-and-cook” approach and was pleasantly surprised by how well it turned out—creamy sauce, tender chicken, and perfectly cooked pasta with very little hands-on time.
What is an Instant Pot
An Instant Pot is a popular multi-function electric pressure cooker that also often acts as a slow cooker, rice cooker, steamer, and sauté pan. They’re convenient for getting meals on the table quickly. Different models offer different features, but most are simple to use for basic pressure-cooking recipes like this one.
This recipe uses just a few ingredients and can be adapted with optional seasonings or vegetables. If you want to add vegetables, you can try adding them while cooking, but results will vary depending on the vegetable and size of pieces. Seasonings like Italian seasoning, oregano, or basil are easy additions if you’d like more flavor.
Instant Pot Chicken Alfredo Ingredients
- Jarred Alfredo sauce (about 16 ounces)
- Chicken broth (about 14.5 ounces)
- Fettuccine, broken in half (about 1/2 pound)
- Boneless skinless chicken breasts, cut into small cubes (about 1 pound)
- Optional toppings: freshly grated Parmesan and chopped fresh parsley
How to Make Instant Pot Chicken Alfredo
- Pour the Alfredo sauce and chicken broth into the bottom of the Instant Pot and stir to combine.
- Add the broken fettuccine and the cubed chicken, stirring to ensure the pasta and chicken are submerged and not clumped together.
- Secure the lid and set the Instant Pot to high pressure for 10 minutes.
- When the cooking cycle finishes, allow a 10-minute natural release, then carefully release any remaining pressure. Check that the pasta and chicken are cooked through. If needed, replace the lid (do not pressurize) and let the pot sit for another 5–10 minutes so the hot liquid finishes cooking the ingredients.
- Serve topped with Parmesan and chopped parsley, if desired.
Note: Cooking times can vary by model and ingredient size. If pasta or chicken appear slightly underdone when you remove the lid, letting the dish rest in the hot liquid will usually finish the cooking.
Serving Suggestions
- Garnish with fresh chopped parsley and freshly grated Parmesan before serving.
- Serve immediately while hot straight from the Instant Pot.
- Pair with a green salad and warm bread or dinner rolls for a complete meal.
- A steamed or roasted vegetable like broccoli or green beans makes a nice side.
Quick Tips for Best Results
- Cut chicken into small, uniform pieces so it cooks evenly during the pressure cycle.
- Stir ingredients well in the pot so pasta and chicken aren’t clumped together and everything is covered by liquid.
- Because pressure cookers and ingredient brands vary, test this recipe once and adjust timing or amounts for your equipment and taste before serving to guests.
- If the sauce is thinner than you like after cooking, whisk in a small slurry of cornstarch and water and simmer briefly using the sauté function or let it thicken off heat.
FAQ
How should I store leftovers?
Store leftovers covered in the refrigerator. This dish is best eaten fresh but will keep for a few days refrigerated.
Can I freeze it?
Freezing is not recommended; Alfredo-based dishes can separate or change texture when frozen and reheated.
How long will it last?
Properly stored in the fridge, expect a few days of quality. Reheat gently on the stovetop or in the microwave.
Substitutions?
You can try different pasta shapes or use vegetable broth instead of chicken broth. I haven’t extensively tested other proteins or significantly different pasta types, so you may need to adjust cooking time.
Can I make it vegetarian, vegan, low-carb, or gluten-free?
Vegetarian: omit the chicken. Vegan: try a vegan Alfredo sauce and plant-based protein, though results will vary. Low-carb or gluten-free: use alternative pastas but expect to experiment with cook time.
