Weeknight spaghetti just got a facelift! This Cajun Spaghetti made with a creamy homemade pasta sauce and homemade cajun seasoning, in under 30 minutes.

Weeknight Spaghetti Just Got A Facelift – She’s Now Creamy, Filled With Veggies And Full Of Smokey Cajun Flavor.
Spaghetti is the best pasta shape, in my opinion. The thin pasta shape allows for the ideal pasta-to-sauce ratio, ensuring you get all the flavors from the sauce in every bite. That’s why I always thought it was such a shame that most people just eat their spaghetti with a store-bought marinara sauce and meatballs. That’s all about to change with this recipe!
This weeknight pasta takes less than 30 minutes to make from start to finish! For the creamy sauce, we use a base of flour, garlic and butter (the roux) with milk. Then, add in the spices and vegetables! While the sauce thickens, boil the spaghetti. Finally, marry the pasta with the sauce, parmesan cheese and a splash of pasta water. This recipe makes four generous portions of Spaghetti, that each come out to 390 calories per bowl!

This is by far the best pasta I have made and this is coming from someone who is not a good cook. It’s an easy recipe but taste like a restaurant dish. A must try!

This pasta was amazing! It had spice, crunch and creaminess which is the only way to eat pasta! Made it with bow tie pasta and turned out so good that we are having it again!
