Begin preparing the ingredients, including cooking your spaghetti to al dente, cutting your veggies, steaming the snow peas/peas/green beans and combining the chicken stock and half & half/light cream together.
Begin by warming the butter on medium heat. Once warm, add the mushrooms and onions and cook until the mushrooms are soft and the excess water has cooked out of them. Also add garlic and don't forget to season with salt & pepper.
Add the flour and continue to stir around for 3-4 minutes to cook off the flour. Add the white wine, continuing to stir to cook off the alcohol, another 3-4 minutes.
Now add the chicken stock and tempered cream a little at a time. Once you have a thick sauce, add Italian seasoning, Worcestershire sauce and hot sauce. Taste the cream sauce and season with salt & pepper, if needed.
Now add the cream cheese and 1+ cup of mozzarella. Stir until well combined.
Now add the cooked pasta, snow peas and chicken and mix until well combined.
Top with the remaining mozzarella and finish cooking in the oven for 25-30 minutes. In the final 5 minutes, place under the boiler to achieve a brown top.
Serve warm, enjoy and cheers 🥂!
