The pressure builds and you start counting down minutes until you eat.
It9s a kinda funny feeling you get when you hear the float valve do its thing. You watch it rise, knowing the deliciousness is just minutes away.

You remember all the times you waited around for dinner that took forever. But with your pressure cooker, that wait feels so much shorter. You feel like you cracked the code to speedy dinners that still taste like you spent hours on it.
The Real Reasons You Will Love This Method
- You get a full meal ready in one pot so there9s barely any clean up.
- The cajun seasoning seeps into the chicken deep making it super flavorful.
- Cooking the pasta right in the broth keeps it tender and tasty.
- The veggies soften just the right amount, with a little crunch left.
- Using pressure cooker means the whole thing comes together way faster than stove top.
- You use natural release so the pasta stays perfect with no mush.
The Complete Shopping Rundown
- 1 ½ tablespoon olive oil, divided
- 1 lb boneless skinless chicken breasts, cut into 1-inch pieces
- 1 ½ tablespoon cajun seasoning (you can find my recipe elsewhere or buy a good one)
- 1 medium red bell pepper, sliced into strips
- 1 medium yellow bell pepper, sliced similarly
- 1 small red onion, halved and thinly sliced
- 2 garlic cloves, minced (about 2 tsp)
- 2 (14.5 oz) cans low-sodium chicken broth
- 1 (14.5 oz) can fire roasted diced tomatoes
- ¾ cup heavy cream, divided
- 12 oz penne pasta (Barilla is kinda my fave for this)
- 2 teaspoon cornstarch mixed with 1 tablespoon water for thickening
- ¾ cup finely shredded parmesan cheese
- 3 tablespoon minced fresh parsley
- Salt and fresh ground black pepper to taste

The Exact Process From Start to Finish
- First, heat 1 tablespoon olive oil in your pressure cooker pot over medium heat. Toss in the chicken pieces, coat 'em with cajun seasoning, and cook until browned and cooked through, about 5 to 7 minutes. You9ll want to pull the chicken out and set it aside for now.
- Keep that pot going with the remaining olive oil. Add your sliced red and yellow bell peppers, red onion, and minced garlic. Saut e9 until veggies soften just right, about 5 minutes. The smell already starts ticking your taste buds.
- Pour in the chicken broth and fire-roasted diced tomatoes. Raise the heat to bring the mix to a boil. Watch that steam start to rise, you9re almost there.
- Stir in half the heavy cream and return your browned chicken into the pot. Toss in the penne pasta next, pushing it down so it9s submerged in the broth depth properly. Gently stir to spread everything out.
- Seal your pressure cooker lid, check your float valve is up, then set to cook. When it reaches high pressure, let it cook for about 6 minutes. Use natural release after cooking to keep the pasta from getting mushy. This tender pull moment is exactly what you want.
- Once done, open the lid, stir in your cornstarch slurry to thicken the sauce a bit. Add the remaining heavy cream and parmesan cheese. Season with more cajun seasoning if you want some extra heat. Sprinkle fresh parsley on top before serving. That9s it, you9re ready to dig in!
Quick Tricks That Save Your Time
- If you got pre-cut chicken or even leftover cooked chicken, toss it in right away to speed it up.
- Use pre-minced garlic or garlic powder instead if you9re in a rush, it still packs flavor.
- Bell peppers can be sliced ahead or grabbed pre-sliced from the store to save chopping time.
That First Bite Moment
You catch the steam as you lift your fork for the first bite. It9s the kinda heat that hits gentle at first then spreads warmth through your chest.
The pasta feels just right, tender but with a slight bite. You remember how sometimes pasta gets mushy in pressure cookers but this one9s perfect.
The chicken pulls apart easy, juicy and packed full of that deep cajun flavor. The peppers and onion add a little sweet crunch that makes every bite interesting.
Finishing with the creamy parmesan sauce tying it all together just sends your taste buds spinning. You savor this little victory you made in your pressure cooker.
Smart Storage That Actually Works
- Store leftovers in airtight containers in the fridge. It9ll last about 3 to 4 days and reheats nicely.
- When reheating, add a splash of chicken broth or cream to refresh the sauce, so it doesn9t dry out.
- For longer storage, freeze in freezer-safe bags or containers. Thaw overnight in the fridge before reheating gently on the stove or microwave.

The FAQ Section You Actually Need
- Can I use other pasta shapes? Yeah totally. Penne works great but you can swap in rigatoni, fusilli, or whatever you like best.
- What if I don9t have heavy cream? You can use full-fat coconut milk or half-and-half but the sauce won9t be as thick or creamy.
- How spicy is this dish? The cajun seasoning controls the heat. You can adjust it to your taste, add less if you don9t like too much kick.
- What9s the best way to measure broth depth? Make sure the pasta is just covered by the broth but not swimming. About 1 to 2 inches depth works real good so pasta cooks evenly.
- Do I need to stir during cooking? Nope, just give it a gentle stir before sealing the lid. After cooking, stir it well to mix everything nice.
- How do I know when to natural release? Once cook time ends, let the pressure come down on its own until float valve drops. That means it9s safe to open and your pasta9s tender pull is perfect.
