How to make lightened creamy cajun shrimp pasta
This creamy cajun shrimp recipe may seem overwhelming at first, but it truly comes together so easily! The steps below should make the process smooth and simple.
To begin, prepare the spaghetti according to the directions on the box. Drain the noodles and keep them warm by putting the lid back on the pot.
Then, use a large bowl to mix together the shrimp, half of the cajun seasoning, and the salt and pepper.
Heat a large dutch oven over medium-high heat. Add the oil. Once hot, add the shrimp and cook it for 3-4 minutes total, stirring occasionally.
Remove the shrimp from the heat and place them back in the bowl.
Then, add the butter and the minced garlic to the same hot pot. Mix and let cook for 30 seconds on medium-high heat, and then add the diced tomatoes and milk.
Remove 1/4 cup of the milk mixture from the pot and place it in a bowl. Whisk in the flour. This will create a roux, which is a thick sauce that will help to thicken the main dish. Once everything is mixed together, add the roux back into the main pot and whisk until combined.
Next, stir in the parmesan cheese and the remainder of the cajun seasoning. Let it simmer over medium heat for 5-6 minutes, or until it has thickened. Be sure to stir occasionally. Once thick, turn off the heat.
Add the shrimp and spaghetti to the sauce. Mix together using tongs until everything is combined. Then, add the bag of baby spinach and mix. It will take a few minutes to wilt down, so you can either put the lid on to let it steam or keep mixing until it has wilted.
Top with chopped parsley and extra parmesan and serve!
