Begin by spiralizing the zucchinis into noodles using a spiralizer. Set aside.
In a large skillet, heat the olive oil over medium heat. Add the cubed chicken breast and season with salt and pepper. Cook until the chicken is browned and cooked through, about 6-8 minutes. Remove the chicken from the pan and set aside.
In the same skillet, add the minced garlic and sauté for about 1 minute until fragrant.
Pour in the heavy cream, stirring to combine. Allow it to simmer for 2-3 minutes.
Gradually whisk in the grated parmesan, garlic powder, and nutmeg until the cheese has melted and the sauce thickens slightly.
Add the zucchini noodles to the skillet and toss until they're well coated in the sauce. Cook for an additional 2-3 minutes until the noodles are tender but still have a slight crunch.
Finally, return the cooked chicken to the skillet, tossing everything together until well combined and heated through.
Taste and adjust seasoning if necessary, adding more salt or pepper as needed.
Notes
Serve the dish in bowls, garnished with freshly chopped parsley and an extra sprinkle of parmesan cheese on top for added color and flavor.
