Ingredients for Easy Cheesy Tetrazzini:

spaghetti
vegan butter
yellow onion
cremini mushrooms
vegan evaporated milk – take this recipe for evaporated milk and double it
vegan cream of chicken substitute – same; take this recipe for vegan cream of chicken and double it
vegan Cheddar cheese – I like Violife brand
Montreal Chicken seasoning – it’s vegan; I checked
celery salt
sea salt
ground black pepper
vegan Colby-Jack cheese – again, Violife

Note: Both the vegan evaporated milk and cream of chicken substitute are super easy to make. Promise. The evaporated milk does need a bit of simmer time so plan accordingly.

How to make Easy Cheesy Tetrazzini:

For the pasta:

Cook spaghetti according to package directions. Rinse with cold water, drain, and set aside.

Into a large skillet over medium heat, add vegan butter.

For the sauce:

When butter is melted, add chopped onion and mushrooms. Cook for 3-5 minutes, until softened.

Add evaporated milk, cream of chicken substitute, cheddar cheese, Montreal Chicken seasoning, celery salt, sea salt, and ground black pepper. Stir to combine. Adjust seasoning to taste.

Putting it all together:

Place the cooked spaghetti back into the now-cool cooking pot.

Pour sauce over the spaghetti. Toss to evenly distribute the sauce. The mixture will be very soupy.

Transfer to a prepared 9×13-inch baking dish. Sprinkle Colby-Jack cheese over the top.

Bake, uncovered, 45 minutes.

Serve hot.

Cheers!
