This Cajun Pasta recipe is one I wouldn’t expect my whole family to love, because it sounds like it might be “too spicy” for them. But every time I make this, my kids and husband can’t help but walk by and taste-test the sauce, even before it’s ready to serve. There’s something so irresistible about it!
I’ve purposely kept this dish on the mild side, using easy pantry spices. But I’ve also included tips to make it spicier, if you prefer. It’s easy to taste and adjust as you go.
If you’re familiar with my vegan mac and cheese, you know how creamy and comforting a cashew-based cream sauce can be. It becomes silky smooth in seconds. The hardest part of this recipe is waiting for the water to boil for the pasta, so make sure you start with that first! Everything else will be ready to eat in no time.

Ingredients You’ll Need
- Pasta. I like to use penne pasta for this recipe, but any other shape will work as well. Use gluten-free pasta if you need to, and choose a protein-packed option, like chickpea pasta, if you want a higher protein dish.
- Canned Tomatoes with Green Chilies. If you’ve ever made Rotel dip, you’re probably familiar with this ingredient. The green chilies add a ton of flavor, and we aren’t wasting a drop; the juices from the can will go into the cashew cream sauce.
- Veggies. Red onion and bell peppers pair perfectly with Cajun seasoning. You can also add zucchini or mushrooms, if you like!
- Cashews. These create the creamy sauce, so use unroasted and unsalted ones when possible. If you can only find salted cashews, use half the salt when blending the sauce.
- Pantry Spices. You’ll need 5 basic spices to create a Cajun seasoning: oregano, onion powder, garlic powder, smoked paprika, and cayenne pepper. Plus salt and pepper, to taste.
How to Make Cajun Pasta
Step 1:
Bring a pot of water to a boil over high heat. Season the water with 2 teaspoons of salt, so the pasta will be seasoned when it’s done cooking. As soon as it’s rapidly boiling, add the pasta and cook according to the package directions.
While you wait for the water to boil, add the oregano, onion powder, garlic powder, smoked paprika, and cayenne pepper to a small bowl.
In a large, deep skillet over medium-high heat, add a drizzle of olive oil, then add the chopped onion and bell peppers. Stir often, until the veggies soften, about 8 minutes. Then add the spices and stir for one more minute, just until fragrant.
Tip: If your veggies start to cook too quickly, leaving a browned residue in the pan, use a splash of pasta cooking water to deglaze the pan. This will make all the browned bits transfer to the veggies, making them extra flavorful.

Step 2:
Open the can of diced tomatoes with green chilies, and drain the juices into a small blender. Add the cashews, a half teaspoon of salt, and a half cup of water. Then secure the lid and blend until smooth, about 60 seconds.
Pour the canned tomatoes into the pan with the veggies and spices, then add the cashew cream sauce.
Step 3:
When the pasta is done cooking, drain away the water and add the pasta to the pan. (Note: You can reserve some of the cooking water if you think you’ll want a creamier sauce.)
Stir well over medium heat until the pasta is coated in the cream sauce and everything is warm. Season to taste with additional salt, if needed. (I usually add another 1/4 teaspoon.)
This Cajun pasta is ready to serve right away with any toppings you love. You can stir in cooked protein, if desired, or garnish with green onion and cilantro. If the sauce becomes too thick, add a splash of the reserved cooking water.
Storage Tip: You can store leftover pasta in the fridge for up to 4 days. The sauce will thicken when chilled, so it might look dry when you reheat it. Add a splash of water to help it become creamy while reheating, if needed.
Creamy Cajun Pasta (Dairy-Free!)
Ingredients
- 8 ounces penne pasta (gluten-free, if needed)
- 1 tablespoon extra-virgin olive oil
- ½ red onion , chopped
- 2 bell peppers (I use red and green)
- fine sea salt
- ½ teaspoon dried oregano
- ½ teaspoon onion powder
- ½ teaspoon garlic powder
- ¼ teaspoon smoked paprika
- Pinch of cayenne pepper
- 14.5 ounces diced tomatoes with green chilies , reserve juices for sauce
- ½ cup raw cashews
- chopped green onions or cilantro , for garnish
Instructions
- Bring a pot of water to a boil (I add 2 teaspoons of salt), then cook the pasta according to the package directions. When it's done cooking, drain and set aside.
- While the pasta is cooking, heat the olive oil in a separate large skillet. Sauté the onion and bell peppers until they start to soften, about 8 minutes. Season the veggies with ½ teaspoon of salt as you stir.
- In a small bowl, combine the oregano, onion powder, garlic powder, smoked paprika, and cayenne pepper. Start with just a pinch of Cayenne pepper, because you can always add more later, but you can't undo spice! An ⅛ teaspoon of cayenne pepper makes this dish quite spicy, so I recommend starting with less if you don't like spicy food. Set this aside until the veggies are tender.
- To make the creamy sauce, pour the juices from the diced tomatoes directly into your blender. Then add the cashews, ½ cup of water, and ½ teaspoon of salt. Blend until very smooth, with no visible cashew pieces remaining. (Note: This works best in a personal-size blender due to the small batch size.)
- Once the veggies are tender, add in the spice blend and stir briefly. Then, add in the diced tomatoes, the creamy sauce, and the drained pasta, and toss well.
- Taste the pasta, and adjust any seasoning, as needed. You can add more salt to boost the flavor, some freshly ground black pepper, and another pinch of cayenne pepper, if you like things spicier, or a little more smoked paprika, for more of a smoky flavor. Serve warm, with any extra garnishes you like. (I added chopped green onions and cilantro.) Leftovers can be stored in an airtight container in the fridge for up to 3 days.

Every Saturday I make a big pot of pasta and this recipe is one of our favorites. It’s so flavorful and I love that it’s full of veggies. I use a bit less onion and tomatoes and swap zucchini for the mushrooms per my family’s tastes. It’s a winner!
Excellent! Our family (3 carnivores and 1 gf vegetarian) loved it!
This was so good!!! I added shrimp for extra protein, but it also would have been delicious with sliced sausage. Great recipe for Mardi Gras
Megan did it again! Delicious!
I can always trust these recipes because I know you test them and have different adjustments, substitutions etc. Thank you!
This was absolutely delicious! And so easy. The family all loved it. A good suggestion with the green bell pepper. I omitted the mushrooms and added shredded chicken. We’ll definitely make this again.
