Step-by-Step Instructions
Prepping the Chicken
First, take your diced chicken and put it in a bowl. Sprinkle the Cajun seasoning over the chicken. Mix it well until every piece is coated with the spice. This step makes the chicken flavorful and spicy.
Sautéing the Ingredients
Set your Instant Pot to 'Sauté' mode and add olive oil. Once the oil is hot, add the seasoned chicken. Cook it for about 5 minutes until it turns brown. Remove the chicken and set it aside. Next, add the diced onion, garlic, and bell pepper to the pot. Sauté these veggies for about 3-4 minutes. You want them to soften and become fragrant.
Cooking Under Pressure
Now, return the chicken to the pot. Add the drained diced tomatoes, chicken broth, and penne pasta. Stir everything together. Close the Instant Pot lid and set it to manual high pressure for 6 minutes. After the cooking time is up, let the pressure release naturally for 2 minutes. Then, carefully turn the valve to release any remaining pressure.
Final Touches
Open the pot and stir in the heavy cream. Let it heat for a couple of minutes. Then, add the shredded cheddar cheese. Stir until it melts and creates a creamy sauce. Taste it and add salt and pepper if you need to. Finally, serve it hot and garnish with freshly chopped parsley.
Tips & Tricks
Adjusting Spice Levels
To make the dish milder, use less Cajun seasoning. You can start with one tablespoon. For heat, add extra seasoning or a pinch of cayenne. Taste as you go. This way, you can find your perfect spice level.
Ensuring Creaminess
For a creamy texture, use heavy cream. Stir it in slowly after cooking. Make sure the heat is low to avoid curdling. You can also add more cheese for extra creaminess. Cream cheese or mascarpone can work well too.
Timing Suggestions
Cook the penne pasta for six minutes under pressure. This timing gives you perfect pasta. If you like it softer, add one or two minutes. Remember, the pasta will cook a bit more after you release the pressure, so don’t overdo it!
Pro Tips
- Perfect Cajun Seasoning: For an authentic flavor, use a homemade Cajun seasoning blend with herbs and spices tailored to your taste. Adjust the heat level by adding more or less cayenne pepper.
- Cook Pasta Al Dente: Since the pasta will continue to cook slightly after pressure cooking, aim for slightly undercooked pasta to maintain the perfect texture.
- Creamy Consistency: To achieve an ultra-creamy sauce, slowly stir in the heavy cream and cheese off the heat to prevent curdling.
- Fresh Herb Finish: Add fresh herbs like basil or thyme as a final garnish for an extra burst of flavor and freshness that complements the dish beautifully.
Variations
Protein Options
You can swap chicken for many proteins in this dish. Shrimp adds a nice touch. Just make sure to cook it for a shorter time. Sausage is also a great choice. You can use spicy sausage for extra heat. For a milder taste, choose sweet Italian sausage. Both options work well with the Cajun flavor.
Pasta Alternatives
If you want to try different pasta, go for it! Penne is great, but you can use fusilli or rotini too. These shapes hold sauce well. You can even use whole wheat pasta for added fiber. Gluten-free pasta is also an option if needed. Just follow the cooking times on the package.
Vegetarian/Vegan Options
You can make this dish plant-based easily. Replace chicken with tofu or tempeh. Use vegetable broth instead of chicken broth. For a creamy texture, try coconut milk. Nutritional yeast can replace cheese for a cheesy flavor. Fresh vegetables like zucchini or mushrooms can add more depth.

FAQs
Can I use frozen chicken?

Is it possible to make this recipe in a slow cooker?
Yes, you can adapt this recipe for a slow cooker. Start by sautéing the chicken and vegetables in a pan on the stove. Then transfer them to the slow cooker.
