- 1 and 1/2 cups milk: Keeps the cheese sauce creamy and perfectly pourable.

How to Make Cajun Mac and Cheese Recipe
Step 1: Cook Pasta and Sauté Sausage
Start by boiling a large pot of water and cooking your elbow noodles until they are just al dente — tender but still with a slight bite. While the pasta cooks, heat the olive oil in a skillet and sauté the diced red peppers and andouille sausage until they’re beautifully browned and fragrant. This step builds a wonderfully savory foundation with pops of sweetness from the peppers and smoky spice from the sausage.
Step 2: Prepare the Cheese Sauce
In a separate saucepan, melt the butter gently then whisk in the flour and salt to form a roux. This mixture will thicken your sauce, so whisk it well to avoid any lumps. Slowly pour in the milk while stirring constantly, and once the sauce starts thickening, add in 4 cups of the grated white Cheddar cheese along with the Cajun seasoning. Keep stirring until the cheese melts into a silky, creamy sauce that’s bursting with spicy Cajun flair.
Step 3: Combine and Bake
Drain the cooked pasta and mix it thoroughly with the sautéed pepper and sausage mixture. Pour in the luscious cheese sauce and combine everything until every noodle is coated in cheesy goodness. Transfer this mixture to a baking dish, top generously with the remaining cheese, and sprinkle smoked paprika over the top. Bake the dish until it’s bubbly and golden, allowing those flavors to blend and the top to develop a gorgeous crust that adds delightful texture.
How to Serve Cajun Mac and Cheese Recipe

Garnishes
To elevate your Cajun Mac and Cheese Recipe, consider fresh garnishes like chopped green onions or parsley. Their bright herbaceous notes contrast beautifully with the rich, creamy sauce and add a fresh pop of color that makes the dish even more appetizing.
Side Dishes
This dish is rich and hearty, so pairing it with simple, crisp sides works wonders. Think along the lines of a light green salad with a tangy vinaigrette or roasted vegetables that bring a touch of earthiness and crunch to the table, balancing the creaminess perfectly.
Creative Ways to Present
For a fun twist, serve this Cajun Mac and Cheese Recipe in individual ramekins or even inside hollowed-out bell peppers for a colorful, convenient presentation. You could also layer it in a casserole with extra sausage or sprinkle some crispy bacon bits on top for a bold, indulgent treat.
Make Ahead and Storage
Storing Leftovers
Any leftovers from your Cajun Mac and Cheese Recipe can be stored in an airtight container in the refrigerator for up to 3 days. Make sure it’s cooled completely before sealing to keep the texture and flavor intact.
Freezing
You can freeze this dish if you want to enjoy it later. Portion it into freezer-safe containers and store for up to 2 months. When freezing, avoid adding the smoked paprika topping to prevent it from altering flavor during storage.
Reheating
Reheat leftovers gently in the oven at 350°F until warmed through to maintain the creamy texture. If you’re in a hurry, the microwave works great too — just add a splash of milk and stir halfway through heating to keep it from drying out.
FAQs
Can I use other types of sausage?
Absolutely! While andouille sausage provides that classic Cajun spice, you can substitute with smoked sausage or chorizo if you prefer a different flavor profile. Just be mindful of seasoning adjustments.
Is this Cajun Mac and Cheese Recipe very spicy?
The heat level is lively but balanced thanks to the Cajun seasoning and smoked paprika. You can always adjust the amount of seasoning to suit your preference, making it milder or spicier as you like.
What type of cheese works best?
White Cheddar is ideal for its sharpness and great melting qualities, but feel free to mix it with Monterey Jack or Mozzarella for a different creamy texture.
Can I make this recipe vegetarian?
You can replace the sausage with smoked tofu or sautéed mushrooms and increase the Cajun seasoning to keep that bold flavor alive without the meat.
Do I need to pre-cook the sausage before baking?
Yes, sautéing the sausage beforehand ensures it’s fully cooked and releases its flavorful oils into the dish, giving the mac and cheese that signature smoky depth.
