In a large pot, heat olive oil over medium heat for 2 minutes. Cut chicken breasts into 4 strips, season on both sides with salt, pepper, and onion powder.
Sear in pan for about 3 minutes on each side, and add garlic to cook for about 30 seconds. Make the sauce while the chicken is cooking.
For the sauce:
While chicken is cooking, combine water, milk, chicken bouillon and flour in a bowl and whisk until smooth.
To the pot, add the garlic and cook for about 30 seconds. Add in the water/milk mixture, and gnocchi.
Bring to a simmer, stir occasionally, and cook for 5-7 minutes, until the sauce thickens, gnocchi is soft and chicken is cooked through (165℉ internal temp).
Add in fresh grated parmesan, fresh lemon juice, and lemon zest and stir. Garnish with basil and parmesan to serve.
Notes
Don't use pre shredded parmesan, it has anti caking additives that make the sauce grainy in texture if used. Fresh grated is best! Add more or less lemon to taste. Store refrigerated for up to 4 days. The lemony taste gets stronger the next day or two.
