How to make Tetrazzini

First preheat your oven to 350°F and prepare a 10 inch diameter casserole. Grease it with a bit of olive oil or vegan butter.

Heat a skillet with olive oil. Add the onion, garlic, and mushrooms, then fry for around 4 minutes. After that, add vegan chicken cubes and fry for 5 minutes more. Season with a pinch of salt and pepper.

Now melt vegan butter in a casserole or pot. For making a white sauce, stir flour into the butter. Add the almond milk slowly, while stirring, until the sauce thickens. Seasoned with nutmeg, salt and pepper. Then add half of the vegan parmesan and set aside.

Mixed pasta, vegan chicken, mushrooms, sauce are transferred into a casserole and covered with vegan cheese.

Now give the Tetrazzini into the oven and bake it for about 25 minutes until the cheese is melted. Remove from the oven and let the casserole cool down for at least 5 minutes before serving it on plates or in bowls.

Tips and tricks

Leftovers will stay fresh in the fridge properly stored for 4 days. So you can make it in advance for meal prep.

Freezing: after cooking it, make sure to let it completely cool down before covering in plastic wrap, and freezing.

If you want to reheat it again from the freezer, keep in mind to thaw it completely. The easiest way is to take it from the freezer overnight so you have it on hand thawed right in the morning

After thawing start with a low oven temperature. I would suggest 300°F. Bake until it is warm to your preferences, check from time to time to ensure it is your desired result.
