Healthy Spaghetti Squash Alfredo with Chicken and Broccoli

If you’re looking for something healthy, quick, easy and very satisfying I’ve got you covered. This spaghetti squash gets filled with chicken and broccoli and smothered in a creamy cashew Alfredo sauce. Oh also, it’s also made with less than 10 ingredients. The sauce is made with softened cashews, onions, garlic, nutritional yeast and some salt, garlic powder and water. Say what!? You heard me right. It may sound weird but I promise you it is absolutely delicious.  If you’re questionable I urge you to give it a try but you could easily substitute an Alfredo sauce made with milk and parmesan cheese too. On the other hand, if you want to omit the chicken and make this vegan this is a perfect vegan dinner. Just add peas in place of the chicken. 

What You'll Need

  • Spaghetti Squash – 1 medium sized spaghetti squash or frozen works too!
  • Broccoli – 2 medium sized heads of broccoli for about 3 cups of bite sized pieces. You can also use frozen broccoli thawed and drained. 
  • Chicken – I love to use a rotisserie chicken for this because it makes it that much faster!
  • Cashews – You want to use raw cashews that have either been soaked in water overnight or you can gently boil them for 10 minutes. 
  • Onion – 1 medium onion
  • Garlic – 2 large garlic cloves
  • Nutritional Yeast – Nutritional yeast adds a cheesy umami flavor to the Alfredo sauce without adding cheese. It also happens to have a lot of vitamins and minerals as well as all nine essential amino acids making it a complete protein. 
  • Garlic Powder – Because I love garlic powder. It adds more of a roasted garlic flavor vs a sharp garlic flavor. 
  • Fresh Bread Crumbs – I prefer fresh bread crumbs that I make from a few slices of bread that I throw in the blender or food processor. You can substitute store bought bread crumbs or panko if you wish! 

To Make the Cashew Alfredo Sauce

  • Soak or Gently Boil the Cashews
    • Cover the cashews with water and allow to soak overnight at room temperature. 
    • Bring the cashews and water up to a gentle boil and allow to simmer for 10 minutes. 
    • Drain the cashews
  • Sauté the Onions & Garlic
    • In a pan over med-low heat add a little olive oil, the chopped onions and a little salt. Cover and stir occasionally for about 7 minutes. 
    • Add the garlic and sauté 1-2 minutes longer. 
  • Blend
    • In a blender combine the softened cashews, the onions and garlic, nutritional yeast, garlic powder (optional), salt and water. 
    • Blend until smooth.
  • Season to taste!

    • My favorite method for easy juicy chicken breast. Learned from Katie Lee Biegel on the Kitchen.
