Dairy-Free Cajun Pasta

Cashew Cream Cajun Chicken Pasta

The sauce is a blend, not a reduction. Cashews soaked thirty minutes and blitzed with broth carry the cream here, so nothing has to be simmered down to thicken it.

The cream in this pasta is made in a blender before the skillet is ever hot. Cashews soaked for half an hour go in with broth, garlic, lemon and a teaspoon of the Cajun seasoning, and come out as a sauce that is already the consistency it will be served at.

That changes the cooking. There is no reduction stage and no risk of splitting a dairy sauce over heat — the cashew cream only needs two to three minutes on medium-low to come up to a gentle simmer before the pasta and chicken go back in.

Why This Recipe Works

  • Soaking the cashews is what lets them blend completely smooth; the recipe is specific about thirty minutes in hot water rather than a quick rinse.
  • Splitting the Cajun seasoning between the sauce and the chicken rub seasons the dish in two places, so the heat is in the sauce rather than only on the surface of the meat.
  • Searing the chicken and removing it before the vegetables go in keeps it from overcooking while the peppers take their four to five minutes.
  • Reserved pasta water does the final adjusting, a splash at a time, which is how a blended sauce is brought to glossy rather than by adding more fat.

Ingredient Notes

Raw cashews
Raw rather than roasted, and soaked 30 minutes in hot water. Roasted cashews carry a toasted flavour the sauce is not built around.
Nutritional yeast
Two tablespoons, optional, there for a cheesy note — it is not a thickener.
Cajun seasoning, divided
A tablespoon and a half total: one teaspoon into the blended sauce, the rest onto the chicken.
Butter
One tablespoon, and the recipe offers more olive oil instead — which is what keeps the whole dish dairy-free if you want it that way.

How to Make It

  1. Soak the cashews

    Soak the cashews in hot water for 30 minutes, then drain. This is the step that decides whether the sauce blends silky or gritty.

  2. Cook the pasta and save the water

    Bring a large pot of salted water to the boil, cook the pasta until al dente, and reserve a cup of the cooking water before draining.

  3. Blend the cashew cream

    Blend the soaked cashews with the broth, half a cup of water, garlic, lemon juice, nutritional yeast, a teaspoon of the Cajun seasoning and salt until completely smooth and silky.

  4. Season the chicken

    Pat the chicken dry and toss it with the remaining Cajun seasoning, smoked paprika, cayenne, onion powder, garlic powder, salt and pepper.

  5. Sear and set aside

    Heat a tablespoon of olive oil in a large skillet over medium-high and sear the chicken 3 to 4 minutes per side until golden and cooked through, then move it to a plate.

  6. Soften the peppers

    Add the remaining olive oil and the butter to the skillet and sauté the onion and bell peppers 4 to 5 minutes until tender-crisp.

  7. Deglaze

    Deglaze the pan with a splash of pasta water, scraping up the browned bits the chicken left.

  8. Warm the sauce through

    Turn the heat to medium-low, pour in the cashew cream and stir until it is gently simmering and thickened, 2 to 3 minutes.

  9. Bring it together

    Add the cooked pasta and the chicken and toss, adding pasta water a splash at a time until the sauce is glossy and coats everything.

  10. Finish and taste

    Stir in the cherry tomatoes if using and the parsley, then adjust salt, pepper and heat. Parmesan on top is optional.

Building the Cashew Cream

This sauce is assembled in a blender and then only warmed, so each component is doing one job and none of them is reduction.

  1. The body

    30 minutes in hot water

    1 cup raw cashews, soaked 30 minutes and drained

    All of the thickness. Nothing else in the sauce is a thickener, which is why the soak matters.

  2. The liquid

    1 cup broth plus 1/2 cup water

    Takes the blended nuts down to a pourable cream rather than a paste.

  3. The savour

    3 cloves garlic, 2 tbsp nutritional yeast, 1 tsp Cajun seasoning

    Seasons the sauce itself rather than relying on the chicken rub to carry the dish.

  4. The lift

    1 tbsp lemon juice and salt

    Acid against the fat of the nuts, blended in rather than squeezed over at the end.

Then tasteWarmed 2 to 3 minutes on medium-low until gently simmering, then loosened with reserved pasta water a splash at a time until glossy.

Success Tips

  • Blend longer than feels necessary. Completely smooth is the stated target, and a slightly grainy cashew cream does not smooth out later in the pan.
  • Keep the sauce at medium-low once it goes in; it is already at serving consistency and hard boiling only thickens it past where you want it.
  • Hold back some pasta water even at the end — the sauce keeps tightening off the heat.

Serving Ideas

Four servings, and the Parmesan at the end is marked optional, so the dish can stay entirely dairy-free by using olive oil in place of the butter.

Frequently Asked Questions

Do the cashews really need soaking?

Yes — 30 minutes in hot water, per the recipe. It is what allows them to blend completely smooth, which is the whole basis of the sauce.

Can I make this fully dairy-free?

The recipe already offers more olive oil in place of the tablespoon of butter, and the Parmesan at the end is optional. The cream itself contains no dairy.

What if the sauce gets too thick?

Add reserved pasta water a splash at a time while tossing, which is how the recipe brings it to glossy.

Blend soaked cashews, broth, 1/2 cup water, garlic, lemon juice, nutritional yeast, 1 teaspoon Cajun seasoning, and salt until completely smooth and silky. Pat chicken dry and toss with remaining Cajun seasoning, smoked paprika, cayenne, onion powder, garlic powder, salt, and pepper. Heat 1 tablespoon olive oil in a large skillet over medium-high; sear chicken 3–4 minutes per side until golden and cooked through. Transfer to a plate. Add remaining olive oil and butter to the skillet; sauté onions and bell peppers 4–5 minutes until tender-crisp. Deglaze pan with a splash of pasta water; scrape up browned bits. Reduce heat to medium-low; pour in cashew cream and stir until gently simmering and thickened, 2–3 minutes. Add cooked pasta and chicken; toss, adding pasta water a splash at a time until glossy and saucy. Stir in cherry tomatoes (if using) and parsley; adjust salt, pepper, and heat.
