In a large pot or deep skillet, heat the olive oil over medium heat. Once hot, add the diced chicken breast. Season with salt, pepper, and Italian seasoning. Cook for approximately 5-7 minutes, stirring occasionally, until the chicken is golden brown and cooked through. Remove the chicken from the pot and set it aside in a bowl.
In the same pot, add the diced onion. Sauté for about 3-4 minutes until it becomes translucent. Next, add the minced garlic and cook for an additional 1-2 minutes, stirring constantly until fragrant.
Carefully pour in the chicken broth, scraping any brown bits from the bottom of the pot. Bring the mixture to a gentle simmer.
Add the potato gnocchi into the simmering broth. Follow the package instructions, typically about 2-3 minutes, or until they float to the surface, indicating that they are cooked.
Reduce the heat to low and stir in the heavy cream. Mix thoroughly, allowing the sauce to gradually thicken for about 2-3 minutes.
Return the cooked chicken to the pot along with the fresh spinach. Stir gently until the spinach wilts and the chicken is heated through, roughly 2-3 minutes.
Taste the dish and adjust the seasoning by adding more salt, pepper, or Italian seasoning as desired to enhance the flavors.
Once everything is well combined and has a creamy consistency, remove the pot from heat.
