The Complete Shopping Rundown
You’ll need some key ingredients for this dish. Here’s what you want to grab from the store or your pantry.
- 8 ounces of penne pasta
- 1 pound boneless skinless chicken thighs, cut into bite size pieces
- 1 tablespoon extra virgin olive oil
- 4 teaspoons Cajun seasoning
- ½ cup shredded sharp cheddar cheese
- Parsley for serving, if you’re feeling fancy
- 2 tablespoons butter
- 2 tablespoons flour
- ¼ cup grated Parmesan cheese
- 2 cups milk
Each of these plays a part in building that creamy, spicy vibe. Your pasta gives you a nice bite, chicken soaks in Cajun heat, and the cheesy sauce pulls it all together. Don’t skip the parsley unless you want it looking kinda plain.
Your Complete Cooking Timeline
Step one, you preheat the oven to 375°F so it’s ready to finish the bake.
Step two is cooking your penne pasta until it’s just right and al dente. Drain and set it aside for later.
Next, heat olive oil in a large skillet over medium-high heat. Toss in your chicken with 2 teaspoons of Cajun seasoning. Cook it up for around 6 to 8 minutes until it’s browned and cooked through. Then set that chicken aside.
For step four, melt butter in the same skillet over medium heat. Whisk in flour and keep stirring until it turns a golden color, about 1 or 2 minutes.
Step five, slowly whisk in your milk. Keep cooking and stirring until your sauce thickens, about 3 to 4 minutes. Then stir in Parmesan, ¼ cup shredded cheddar, and the last 2 teaspoons of Cajun seasoning. The cheese melts in and makes the sauce all smooth and creamy.
Finish with step six by mixing the chicken and pasta into that sauce. Pour everything into a greased baking dish, top with the remaining ½ cup sharp cheddar cheese, and bake for 15 to 20 minutes. Your cheese should be bubbly and melted, perfect for serving with some chopped parsley if you want.

Easy Tweaks That Make Life Simple
- Use pre-cooked rotisserie chicken instead of raw to cut down active cooking time.
- Swap penne for rigatoni or any pasta shape you got handy.
- Add frozen bell peppers with the chicken if you want a quick veggie boost.
- Make the sauce in the pressure cooker itself right after chicken to save on dishes.
These tweaks help you tailor the meal based on what you got and how much time you wanna spend. Keeps life simple and tasty without sweating it too much.
What It Tastes Like Fresh From the Pot
Your first bite hits with creamy cheesy sauce that wraps every piece of pasta. It’s rich but not too heavy.
Those Cajun spices kick in next with a warm, spicy hug that’s just right. Chicken bits carry that flavor deep inside, keeping it juicy and lively.
The melting sharp cheddar on top gives that crunchy golden crust finish, adding a nice contrast to the softness below. A sprinkle of parsley brightens things up just a bit, making every mouthful a comfort hug.

Making It Last All Week Long
- Refrigerate: Store leftovers in airtight containers and eat within 3 to 4 days for best taste.
- Freeze: If you wanna save it longer, freeze in portions sealed tight in freezer bags or containers. Thaw overnight in fridge before reheating.
- Reheat gently: Use a microwave or stovetop on low heat with a splash of milk so sauce stays creamy, not dry.
- Meal prep tip: Pack individual portions for work lunches. It reheats real good and feels fresh with a quick warm up.
Getting your portions and storage right keeps the pasta bake tasting great, no matter when you dig back in.
Your Most Asked Questions Answered
- Can I use chicken breasts instead of thighs? Sure thing. Just keep an eye on cooking time since breasts cook faster and can dry out if overcooked. Adjust to 5-6 minutes if you’re using the pressure cooker.
- What if I don’t have penne? Any pasta will do. Rigatoni, elbows, shells, whatever’s sitting in your pantry. Just watch cooking times since some shapes cook faster.
- Do I have to use sharp cheddar? Nope, but it gives a nice bite. You can swap for mozzarella if you want milder cheese or a mix of cheeses for your own twist.
- How do I make it spicier? Add more Cajun seasoning or toss in a pinch of cayenne pepper while cooking the chicken. Easy way to turn up the heat.
- Can I do the whole thing in the pressure cooker? You sure can. Brown the chicken right in the pot, make the sauce there, then toss in pasta and chicken before pressure cooking. Just be sure to quick release to avoid overcooking pasta.
- How do I know when natural release is better than quick release? Natural release works better for meats that need resting to stay juicy. Quick release is great for pasta dishes so it doesn’t turn mushy and cooks just right. For this recipe, use quick release after pressure cooking chicken and pasta.
