Dive into the yummiest dairy-free Cajun shrimp pasta — dinner perfection

I’m always experimenting to make at-home pasta night feel special, and shrimp is one of my go-to proteins because it cooks so fast and adds an elevated flavor to simple weekday meals. This recipe brings smoky Cajun spices together with sautéed peppers, garlic, a touch of tomato paste, and a cashew cream that gives the sauce a luxurious texture.

Cashew cream is a favorite dairy-free trick in my kitchen: when made from raw cashews it blends into a smooth sauce that mimics the mouthfeel of a cream-based pasta but stays entirely plant-based. In this recipe, the cashew cream softens and balances the bold Cajun flavors, creating a dish that’s both comforting and lively.

It’s easy enough for a weeknight yet elevated enough to serve to guests. If you like shrimp as much as I do, this one will quickly become a repeat recipe.

Key ingredients

Although the ingredient list looks long, many items are pantry spices. Once the cashews are soaking and the peppers and onion are chopped the recipe moves quickly.

Peeled and deveined shrimp

Use peeled shrimp for speed. Tails on add flavor and can help prevent overcooking, but tails off are easier to eat—both work well.

Savory spices

The spice mix is what gives the dish its Cajun personality. You can use a pre-made Cajun blend or combine kosher salt, black pepper, onion powder, garlic powder, dried oregano, paprika, dried thyme, and a pinch of cayenne for heat.

Raw cashews

Raw, unsalted cashews are essential for a creamy cashew sauce. They soak and blend into a silky consistency that becomes the base of the dairy-free sauce.

Note on pasta: I used gluten-free spaghetti for this version. If you use regular wheat pasta, you may be able to stretch the sauce a bit farther and adjust the cooking time according to the package. Any pasta shape will work—pick your favorite.

How to make dairy-free Cajun shrimp pasta

This recipe takes about 40 minutes and uses one skillet, one large pot for pasta, and a high-speed blender to make the cashew cream. Minimal chopping required—just the peppers, onion, and garlic.

Step-by-step overview

1. Soak the cashews. Cover raw cashews with just-boiled water and soak 15–30 minutes until plump.
2. Cook the pasta. Boil generously salted water and cook pasta according to package directions, draining about 2 minutes early. Reserve about 3/4 cup of the cooking water.
3. Combine the spices. Mix kosher salt, black pepper, onion powder, garlic powder, dried oregano, paprika, dried thyme, and a pinch of cayenne (optional) in a small bowl.
4. Sear the shrimp. Pat shrimp dry, toss with part of the spice blend, and sear in hot oil in a large skillet 3–4 minutes until just cooked. Transfer to a plate.
5. Sauté the vegetables. In the same skillet, add a little more oil and sauté diced onion, sliced bell peppers, and chopped garlic until tender. Stir in tomato paste and the remaining spice blend for 1–2 minutes.
6. Make the cashew cream. Drain the soaked cashews and blend them with chicken broth (or vegetable broth) and nutritional yeast until completely smooth.
7. Combine and finish. Return the skillet to medium-low heat, add the drained pasta, cooked shrimp, and cashew cream. Scrape any browned bits into the sauce and simmer gently until it thickens and coats the pasta, adding reserved pasta water if needed to reach the desired consistency.
8. Adjust and serve. Taste and season with salt and pepper. Serve hot garnished with chopped parsley.

Serving suggestions

This pasta shines on its own but pairs beautifully with a crisp green salad or a bright arugula salad with radishes for contrast. Serve with lemon wedges if you like an extra citrusy lift.
