Ingredients for Southern-Style Cajun Pasta

To make this delicious pasta recipe, you'll need to roast some sweet bell peppers, make the creamy Cajun cheese sauce, and whip up simple pecan breadcrumbs. 

And cook the pasta, of course. I recommend starting the pasta water first.

To Make the Roasted Bell Peppers, you'll need:

  • Sweet bell peppers. I love the baby bell peppers. They're so sweet! But regular peppers will work too. 
  • Dried parsley. You could swap in another favorite dried herb if you like. 
  • Seasonings. Infuse your pasta with flavor from smoked paprika, garlic powder, dried oregano, dried basil, and dried thyme.

Next, make the cream Cajun Pasta Sauce. You'll need:

  • Butter. Use unsalted. 
  • Garlic. If you don't have fresh, substitute with ½ teaspoon of powdered garlic. 
  • Heavy cream. see below for a dairy-free option. 
  • Vegetable stock. Chicken stock will also work. 
  • White wine. Use your favorite dry white.
  • Parmesan cheese. Grana Padano would also work. 
  • Cajun seasoning. Use store-bought or homemade seasoning blend.

How to Make Pecan Breadcrumbs

Do not skip these toasted nutty breadcrumbs. Here's what you need to make them:

  • Pecans. Use pre-chopped to skip a step!
  • Breadcrumbs. You can use panko or Italian-style
  • Cinnamon. To add a touch of warming spice to the Cajun pasta. 

Can I Make Dairy-Free Cajun Pasta?

Yes! To make this sauce dairy-free, simply use vegan butter instead of the regular butter. Then swap the cream with full-fat coconut milk or coconut cream. And use your favorite dairy-free shredded cheese or nutritional yeast instead of parmesan.

What about Gluten-Free?

To make this recipe gluten-free, simply use your favorite gluten-free pasta. I recommend a short pasta to toss with the roasted bell peppers and creamy sauce. 

Storing Leftover Pasta

Store leftovers in an airtight container in the fridge for up to four days. This makes a great meal prep recipe for a satisfying lunch! Reheat in the microwave or on the stove to serve.
