I’ll be honest with you – when I first heard about one pot pasta dishes, I was skeptical. How could you possibly get properly cooked pasta and perfectly seasoned chicken in the same pot without everything turning into mush? But after testing this kosher chicken alfredo recipe dozens of times, I can tell you it works beautifully. The key is layering your ingredients at just the right moments and using the right ratio of liquid to pasta.
Traditional alfredo sauce poses an obvious problem for kosher kitchens since it combines butter, cream, and parmesan with chicken. My solution uses cashew cream and nutritional yeast to create that rich, cheesy flavor without any dairy. The cashews need to soak for at least two hours (I usually start them in the morning), and once blended, they create an incredibly smooth base that rivals any heavy cream sauce.
Making Dairy-Free Alfredo That Actually Tastes Good
The technique here matters more than you might think. You’ll brown the chicken first to get good color and flavor, then remove it while you build the sauce base. The pasta cooks directly in the seasoned liquid, which means it absorbs all those flavors as it softens. I learned through trial and error that you need to stir every few minutes to prevent sticking, and adding the liquid gradually gives you better control over the final consistency.
Why the Cooking Order Matters in One Pot Pasta
This dish works perfectly for weeknight dinners when you want something satisfying but don’t want to wash multiple pots. I serve it with a simple green salad and some crusty bread. The leftovers reheat well too, though you might need to add a splash of vegetable broth to loosen things up.

Ingredients
Method
- Drain and rinse the soaked cashews. Add them to a high-speed blender with 1 cup water. Blend on high for 2-3 minutes until completely smooth and creamy. Set aside.
- Season the chicken pieces with salt and pepper. Heat 2 tablespoons olive oil in a large, heavy-bottomed pot over medium-high heat. Add chicken and cook for 5-6 minutes, stirring occasionally, until golden brown and cooked through. Remove chicken to a plate.
- Reduce heat to medium and add the remaining tablespoon of oil to the same pot. Add diced onion and cook for 3-4 minutes until softened. Add minced garlic and cook for another 30 seconds until fragrant.
- Add the chicken broth, almond milk, Italian seasoning, and red pepper flakes (if using) to the pot. Bring to a gentle boil, then add the fettuccine pasta. Stir well to prevent sticking.
- Cook pasta according to package directions, stirring every 2-3 minutes to prevent sticking. If the liquid level gets too low, add more broth or water as needed.
- When pasta is almost al dente, stir in the cashew cream, nutritional yeast, and lemon juice. Add the cooked chicken back to the pot and stir gently to combine.
- Continue cooking for 2-3 minutes until the sauce has thickened slightly and pasta is tender. Taste and adjust seasoning with salt and pepper as needed.
- Remove from heat and let stand for 2-3 minutes to allow sauce to thicken further. Garnish with fresh parsley before serving.
