Paula Deen’s Chicken Casserole–a quick and easy one-pot Instant Pot pasta made with tender chicken, penne and a creamy cheesy sauce that’s perfect for busy weeknights.

Paula Deen’s Chicken Casserole
This recipe really hit the spot! It comes together so quickly, and the sauce is incredibly flavorful without being too heavy. Even though it’s made with sour cream, it’s not overpowering at all…you’d hardly know it’s there, just that the sauce is smooth and creamy. The chicken and pasta turn out perfectly tender, making every bite so satisfying. It’s also really easy to customize. You can stir in peas, spinach, broccoli, or green beans to add some greens, and you can switch up the pasta with macaroni, rotini, or ziti depending on what you have on hand. This is one you’ll want to add to the rotation! (Recipe adapted from 100K Recipes.)

Notes/Tips
- Serve with green salad, garlic bread or roasted vegetables
- I used my 4 quart Instant Pot*. You can also make this in a 3, 6 or 8 quart pot.
- Use freshly shredded cheese for the best melting.
- For extra protein, you can increase the chicken slightly without adjusting the liquid.
- Store leftovers in an airtight container* in the refrigerator for up to 3-4 days. This can be frozen, but the texture may change slightly due to the dairy.
- Other recipes you can make with sour cream are Soft Lemon Sugar Cookies and Instant Pot No Time To Cook Chicken.
