Cajun Chicken Alfredo takes about 45 minutes from a cold stove to four full bowls. You brown chicken and sliced sausage with garlic in one pot, add cream and cooked penne, then finish with parmesan and parsley. That is the whole recipe.
The part people get wrong is the chicken. It goes in raw and sliced thin, and it has to be cooked through before the cream goes anywhere near the pot. Use a thermometer and look for 165F in the thickest piece. Once cream is in, you can no longer tell by looking.
Everything else is forgiving. The sauce thickens fast at the end, so have the parmesan grated and the parsley chopped before you start. You will not have a free hand once the cheese goes in.
Step-by-Step Instructions
1. Heat the oil
Put a 5 to 6 quart pot over high heat and add the 3 tablespoons of olive oil. Let it get hot, about a minute, so the garlic sizzles the moment it touches the pot.
2. Cook garlic, sausage, and chicken
Add the chopped garlic, sliced sausage, and sliced chicken. Stir often until the garlic picks up color and no pink is left in the chicken. Cut into the thickest strip and check for 165F with a thermometer.
3. Coat with Cajun seasoning
Sprinkle the tablespoon of Cajun seasoning over the pot and stir until the sausage and chicken are evenly coated. Keep the heat high here so the spices bloom in the oil.
4. Add the cream
Pour in the 2 cups of heavy cream and bring it to a boil. Stir the bottom of the pot as it heats so nothing sticks and scorches.
5. Stir in the pasta
Add the 4 cups of cooked penne and stir until every piece is mixed into the sauce. Let it bubble for a minute so the pasta takes on the Cajun flavor.
6. Finish with parmesan and parsley
Turn the heat off and add the parmesan and parsley. Stir until the cheese melts and the sauce coats the pasta thickly. If it looks loose, give it another minute on low heat.
7. Serve
Spoon into four bowls while the sauce is still hot. It tightens quickly as it cools, so bring it to the table right away.
Pro Tips
How to Store Cajun Chicken Alfredo
Refrigerator
Keep leftovers in a sealed container in the fridge for up to 3 days. The sauce thickens cold, so expect a solid set.
Freezer
Freezing is not recommended. Cream sauces can separate and turn grainy when thawed, and the pasta goes soft.
Reheating
Warm gently in a covered pan over low heat with a splash of milk or water, stirring until the sauce loosens. High heat will split the cream.
Variations
- Swap the parsley for a handful of spinach stirred in at the end, as some cooks do, and add cooked shrimp with the pasta.
- Use andouille instead of a plain smoked sausage if you want more heat in the background.
- Trade penne for rigatoni or rotini. Any short pasta with ridges holds the sauce the same way.
Frequently Asked Questions
Q: How do I know the chicken is done before adding the cream?
Use a food thermometer in the thickest strip and look for 165F. Color alone is not reliable, especially once the Cajun seasoning darkens the outside of the meat.
Q: Can I use half and half instead of heavy cream?
You can, but the sauce will be thinner and more likely to break when it boils. Heavy cream is what gives this dish its body.
Q: Why did my sauce turn grainy?
Usually too much heat after the cheese went in. Take the pot off the heat before you stir in the parmesan, and keep the heat low if you need to warm it back up.
Q: Can I make this ahead?
The sauce holds up best fresh. If you want a head start, cook the pasta and slice the chicken and sausage the day before, then do the cooking the night you serve it.
Q: How spicy is it?
That depends entirely on your Cajun blend. Start with half the tablespoon, taste after it coats the chicken, and add the rest if you want more heat.
