Pressure Cooker Chicken Alfredo with Jar Sauce

Comfort food that’s quick, creamy, and weeknight-friendly—this Pressure Cooker Chicken Alfredo with Jar Sauce gives you all of the cozy, indulgent flavor of a classic Alfredo without hours at the stove. Using tender bite-sized chicken thighs, a jar of store-bought Alfredo sauce, and a few pantry-friendly staples, this one-pot meal comes together fast and leaves you with creamy pasta and juicy chicken in a silky sauce. It’s reliable, satisfying, and great when you want a hearty dinner with minimal fuss.

Why this recipe works

This version leans on the pressure cooker to do the heavy lifting: it cooks the chicken quickly and infuses the penne pasta with flavor while keeping cleanup to a minimum. Using jarred Alfredo sauce means you still get that rich, garlicky creaminess without the extra steps of building a sauce from scratch. A touch of cream cheese and butter softens and enriches the jar sauce, and grated Parmesan boosts the savory depth. The result is ultra-creamy pasta with tender chicken in less time than the oven or stovetop method.

Ingredients

• 2lbs skinless boneless chicken thighs, cut into bite sized (about 1″) pieces
• 2 Tbs vegetable oil
• 1 teaspoon kosher salt
• 1 teaspoon ground pepper
• 22oz jarred alfredo sauce (I used Prego in this recipe)
• ¾ Cup broth (can substitute water if you don’t have broth)
• 1 Cup whole milk (can substitute other milks and milk substitute, but flavor may be different in the end)
• 2 Tbs Butter (can substitute imitation butter)
• 4oz cream cheese (can substitute neufchatel or lower fat cream cheese but whole fat cream cheese works best)
• ½ Cup Parmesan Cheese
• 1lb penne pasta
• 1 Cup frozen green peas (optional – I didn’t use in the video or photos. Other frozen small cut veggies work too)
• ½ Cup Parmesan (optional – fresh grated, sprinkled over the top after cooking)

Equipment

• 6-quart (or larger) pressure cooker / electric multicooker
• Wooden spoon or silicone spatula
• Measuring cups and spoons
• Knife and cutting board
• Tongs or slotted spoon

Notes

• All ingredients and steps here follow the ingredient list above—quantities are unchanged.
• If you prefer a thinner sauce, add a splash more broth or milk after pressure cooking and stir over low heat until combined.
• Frozen vegetables like peas, corn, or small-cut carrots can be stirred in at the end to heat through.
• If using a stovetop pressure cooker, follow the manufacturer’s instructions for pressure levels and release methods equivalent to the electric cooker directions below.

Step-by-step instructions

Follow these clear, sequential steps to make the Pressure Cooker Chicken Alfredo with Jar Sauce. The order mirrors the original recipe but with tightened language for ease and consistency.

1. Prep the chicken: Trim any excess fat from the chicken thighs and cut them into approximately 1-inch bite-sized pieces. Pat the pieces dry with paper towels. Sprinkle the chicken with 1 teaspoon kosher salt and 1 teaspoon ground pepper; toss to coat evenly.
2. Heat the oil in the pressure cooker: Set the pressure cooker to the sauté setting (or use the stovetop pot over medium-high heat). Add 2 tablespoons vegetable oil and let it heat until shimmering but not smoking.
3. Sear the chicken in batches: Add half of the seasoned chicken pieces to the hot oil in a single layer. Let them cook without disturbing for about 2 minutes to get a golden sear, then stir or flip and cook another 1–2 minutes until lightly browned on the outside but not cooked through. Remove the browned chicken to a plate and repeat with the remaining chicken, adding a little more oil if the pot looks dry.
4. Deglaze the pot: Pour ¾ cup broth (or water) into the pot and use a wooden spoon to scrape any browned bits off the bottom. This step prevents a burn notice during pressure cooking and captures flavor from the seared chicken.
5. Add jarred sauce and dairy: Pour the 22-ounce jar of Alfredo sauce into the pot, followed by 1 cup whole milk. Add 4 ounces cream cheese (cut into a few chunks so it melts faster) and 2 tablespoons butter. Stir gently to combine so the cream cheese starts to break up and incorporate into the sauce.
6. Return chicken to the pot: Nestle the seared chicken pieces back into the sauce mixture, spreading them out somewhat evenly so they cook through uniformly.
7. Layer the pasta: Scatter 1 pound of penne pasta over the sauce and chicken, pressing it down gently so most of the pasta is submerged or touching the liquid. Do not stir the pasta into the sauce; a light press helps the pasta absorb liquid evenly without clumping.
8. Seal and cook under pressure: Close the pressure cooker lid and set the valve to sealing. Cook on high pressure for 6 minutes. This time allows the penne to cook through while the chicken finishes cooking. If your pressure cooker has different pasta settings, the 6-minute manual high-pressure setting is the target.
9. Quick release and check: When the cook time finishes, perform a quick pressure release according to your cooker’s instructions. Open the lid carefully once pressure has fully released. Stir the contents gently to combine the pasta and sauce. If you see excess liquid, stir to distribute it; the sauce will thicken as it cools. If the pasta needs a minute more, you can switch back to sauté and simmer for 1–2 minutes, stirring frequently.
10. Add cheese and peas: Stir in ½ cup grated Parmesan cheese until melted and incorporated. If you are using the optional 1 cup frozen green peas (or other small-cut frozen veggies), stir them in now; residual heat will thaw them quickly, or warm them for 1–2 minutes on the sauté setting to bring them to temperature.
11. Taste and adjust: Taste a piece of chicken and a forkful of pasta. Add salt or pepper as needed—remember the Parmesan and jarred sauce contribute saltiness, so adjust sparingly. If the sauce tastes too thick, stir in a little more milk or broth until you reach the desired consistency.
12. Serve: Scoop the chicken Alfredo and penne into bowls or onto plates. Sprinkle the optional ½ cup freshly grated Parmesan over individual servings for a bright, salty finish. Serve immediately while hot.

Troubleshooting and tips

• If you get a burn or scorch warning on your cooker, release pressure and remove the lid. Stir and deglaze the bottom with a little extra broth, then continue. Make sure there are no large bits stuck to the pot before resealing.
• For a lighter final texture, you can substitute part of the whole milk with a lower-fat milk, but cream cheese and butter will still add richness.
• If your pasta clumps after pressure cooking, adding 1–2 tablespoons of milk or broth and stirring briskly on the sauté setting helps loosen it up.
• To keep chicken extra tender, avoid overcooking. Cutting thighs into 1-inch pieces helps them cook through quickly and remain juicy.
• For a brighter flavor, finish with a squeeze of lemon or a handful of chopped fresh parsley just before serving.

Make-ahead and storage

This dish stores well in the fridge for 3–4 days. Cool to room temperature, transfer to airtight containers, and refrigerate. Reheat gently on the stove over low heat with a splash of milk or broth to loosen the sauce. You can also reheat individual portions in the microwave, stirring every 30–45 seconds and adding a little liquid if the sauce thickens too much.

Serving suggestions

Serve this Pressure Cooker Chicken Alfredo with Jar Sauce topped with extra grated Parmesan and a sprinkle of freshly cracked black pepper. A simple green salad, garlic bread, or roasted vegetables make excellent partners. For a pop of color, toss in baby spinach at the end and let it wilt in the hot sauce for a minute before serving.

Nutritional notes

This is a rich, comfort-style meal—calorie and fat content is influenced by whole milk, cream cheese, butter, and Parmesan. To reduce calories and fat, use lower-fat milk and a reduced-fat cream cheese, but be aware the sauce will be slightly less creamy. Adding lots of veggies like peas, spinach, or broccoli boosts fiber and nutrients while stretching the dish to feed more people.

Final thoughts

This Pressure Cooker Chicken Alfredo with Jar Sauce is the kind of dinner that feels special but requires minimal time and effort. Searing the chicken adds depth, and the pressure cooker finishes everything quickly so your penne comes out tender and the sauce is lusciously thick. Keep the ingredient amounts the same and follow the step-by-step directions above for consistent results. Whether you’re feeding a family or prepping for a cozy night in, this one-pot meal is dependable, satisfying, and worth making again and again.
