Take comfort to the max with this Cheesy Baked Cajun Pasta! Penne pasta is combined with a rich cheese sauce with cajun flavors and sliced sausage throughout. It’s filling and comforting!
If you love cajun flavors, you’ll also need to try these Spicy Cajun Cheesesteak Sandwiches, this Crispy Cajun Chicken and Pasta, or this Cajun Sausage Pasta.

I can’t believe I’m about to say it, but summer vacation is almost here. My daughter reminds me of it every day. In fact, she has been on countdown mode for several weeks now. 13, 12, 11… Ahhh!
But I am looking forward to summer and slower mornings relaxed schedules. And I’m hoping for lots of summer adventures and lots of ice cream.
But in the meantime, you need to make this Cheesy Baked Cajun Pasta before it’s too hot to turn on the oven. I’m actually a fan of cheesy pasta dishes all summer long, so I could totally see myself making this for a Sunday supper in the middle of July. But that’s just me. 😉
My husband and I both fell in love with this cheesy pasta dish. But I’m slowly discovering that there are very few cheesy pasta dishes that I don’t love! This one is a little different, though, with the cajun spices and the sausage. It is definitely packed with flavor, and definitely packed with comfort!!

Ingredients
- Pasta: I used penne pasta, but any short cut pasta should work.
- Oil: A neutral oil would be best, but olive oil will work, as well.
- Vegetables: You will need onion, bell pepper, and garlic. I used a green bell pepper, but any color should work.
- Flour: The flour will help to thicken the sauce.
- Milk: I used 2% milk, but whole milk will work. If you use skim, the sauce may not thicken up enough.
- Cream Cheese: The cream cheese makes the sauce nice and smooth. It also helps to keep the sauce from separating.
- Seasoning: You will need salt and pepper, along with Cajun seasoning. I like to use my homemade cajun seasoning, but store bought will work, as well.
- Cheese: We’re using a mixture of sharp cheddar cheese and gruyere. You want to make sure to use freshly grated cheese.
- Kielbasa: I like to use kielbasa if at all possible, but if I can’t find it, a smoked sausage will work.
- Breadcrumbs: Panko breadcrumbs make a nice crispy topping. You can also skip the breadcrumb topping, if desired.
- Butter: You just need a little bit of butter to help crisp up the topping.
How to Make Cheesy Baked Cajun Pasta
STEP 1: Cook the pasta. Once tender, drain and reserve the pasta.
STEP 2: Meanwhile, heat the oil then add the onion and pepper. Cook until tender, then add the garlic. Sprinkle the flour over the vegetables.
STEP 3: Pour in the milk and bring it to a simmer. Add in the cream cheese and cook until softened, then add in the cheddar and the gruyere.
STEP 4: In another skillet, heat the remaining oil and add the kielbasa. Cook until browned.
STEP 5: Combine the pasta, kielbasa, and cheese mixture. Pour into a baking dish.
STEP 6: Combine the breadcrumbs and the butter, then sprinkle over the pasta. Bake until bubbling.

Just made this for dinner, and this recipe will be a keeper! I sautéed the sausage and cajun seasoning along with the vegetables. I also used 2-3 times the recipe amount of the seasoning – we like it spicy! So creative to use gruyere and cheddar. Next time, I might try the mixed seafood blend from Trader Joe’s (scallops, shrimp and calamari) in place of sausage for seafood version. Yum! Thank you for posting!
Deborah says
LOVE the idea of using the seafood! I’m so happy you loved it!
Angela says
I made this a few weeks ago and it was great!! I used andouille sausage. I took many many bites before I put it in the oven, and honestly I think I preferred it fresh off the stove rather than baked. So I’ll probably skip the baking step next time. Solid recipe!
Deborah says
I’m so glad you liked it!
Cindy says
Reminds me of my Mama’s Cajun lasagne!
Joanne Bruno says
It is CRAZY that summer vacation is almost here for you guys!! Time is FLYING. I plan on eating cheesy pasta for long after June 21st, though…so bring it on!
Gerry says
Sounds great, but if it is Cajun, why not use Andouille instead of kielbasa? After all, Cajun seasoning alone does not make a dish Cajun. I never use those seasonings. I make my own and I am an old Cajun.
Deborah says
You definitely could use andouille! Kielbasa is easier to find where I live, but a substitution would totally work!

How creamy, cheesey and delicious! I’m excited about summer but super suprised it’s already here!
Hayley @ The Domestic Rebel says
Now this is my kinda comfort food! Purely indulgent, hopelessly cheesy, and filled with flavor!
Shawn@ I Wash You Dry says

Liz says

I will gaze upon it fondly, but never make it. My husband doesn’t eat noodles in any form so unless he’s not home…no pasta for us. *sigh* Looks yummy!
