Instant Pot Cheesy Chicken Pasta

Instant Pot Cheesy Chicken Pasta is my go-to answer for busy weeknights when everyone is hungry and the clock is not on my side. Cubed chicken breast and penne cook together under pressure, then get stirred with freshly grated sharp cheddar, milk, and heavy cream into a rich, velvety homemade cheese sauce that tastes like you spent way more time than you actually did.

I still remember the first Tuesday night I made this, standing in the kitchen in my work clothes, skeptical that raw chicken and dry pasta could come out of a pressure cooker together and taste this good. They did. That glossy, creamy cheddar sauce coating every piece of penne was the kind of comfort food that made everyone at the table go quiet in the best way. This cheesy chicken pasta has earned a permanent spot in the weekly rotation, and once you taste it, it will earn one in yours too.

Everything You Need for This Cheesy Chicken Pasta

I always reach for a block of sharp cheddar and grate it fresh. it makes a night-and-day difference compared to the bagged pre-shredded kind, which contains anti-caking agents that prevent smooth melting. Pro tip: grate a little extra to sprinkle over each bowl right before serving.

• 3.5 cups low-sodium chicken broth
• 1 pound dry penne pasta (macaroni, rotini, or rigatoni work great too)
• 1 pound boneless, skinless chicken breasts, cubed (chicken thighs give a slightly richer result)
• 1 teaspoon dried oregano (Italian seasoning, herbes de Provence, or dried rosemary all work well)
• 2.5 cups sharp cheddar cheese, freshly grated (Colby Jack, Monterey Jack, or mozzarella are excellent swaps)
• 2/3 cup milk
• 1/3 cup heavy cream (half-and-half works for a slightly lighter sauce)

Personal tip: I prefer extra-sharp cheddar over mild here because the bolder flavor holds up beautifully once it melts into the cream and broth. For extra depth, try blending sharp cheddar with a small amount of Gruyere.

Step-by-Step Guide to Making Instant Pot Cheesy Chicken Pasta

I recommend grating your cheese and measuring out the milk and cream before you seal the lid. That way everything is ready to stir in the moment the pressure releases, and the residual heat does all the melting work for you.

Step 1: Add the chicken broth, dry penne pasta, cubed chicken, and dried oregano to the Instant Pot. Stir everything together and press the pasta fully below the broth. Any pasta sticking up above the liquid will cook unevenly or stay hard.

Step 2: Close the lid and set the pressure release valve to SEALING. Select PRESSURE COOK or MANUAL, set to HIGH pressure, and program the timer for 4 minutes. Note: the Instant Pot takes roughly 10 minutes to build pressure before the 4-minute cook timer begins.

Step 3: When the cooking cycle finishes, carefully perform a QUICK RELEASE. Fold a kitchen towel over the steam release valve before turning it to prevent hot steam from spraying. Wait until all pressure has fully released before opening the lid.

Step 4: Open the lid and let the contents cool for 1 to 2 minutes. If there is a lot of liquid pooled at the bottom from the chicken releasing moisture during cooking, drain off a small amount. You need some liquid to melt the cheese smoothly, but too much will thin out the sauce.

Step 5: Add the freshly grated sharp cheddar, milk, and heavy cream directly to the pot. Stir vigorously and continuously until the cheese is fully melted and the sauce is smooth, creamy, and coats every piece of pasta evenly.

Step 6: Taste and add a pinch of salt if needed. Serve immediately while the sauce is at its creamiest.

How to Store and Reheat Cheesy Chicken Pasta

Leftovers keep well in an airtight container in the refrigerator for up to 3 days. The pasta will absorb the sauce overnight and thicken considerably, which is completely normal.

To reheat, microwave in 60-second intervals and stir in a splash of milk between each round to revive the creamy texture. On the stovetop, warm over medium-low heat with a tablespoon of milk, stirring gently until the sauce loosens and everything heats through evenly.

Pro tip: freezing is not recommended for this Instant Pot cheesy chicken pasta. The cheese sauce separates when frozen and thawed, and the pasta texture turns mushy. This recipe is best enjoyed fresh or within 3 days from the fridge.
