24 ounces vegan evaporated milk
20 ounces vegan cream of chicken substitute

Ingredient Notes

Spaghetti –Tetrazzini is traditionally made with long, thin pasta such as spaghetti or linguine. However, other types of pasta can also work well in this dish depending on your personal preference. Fettuccine or tagliatelle are also good choices for this recipe.
Vegan Evaporated Milk – Look for dairy-free evaporated milk on the baking aisle or in the vegan specialty section of your supermarket. If it’s not available in your area, try homemade Vegan Evapored Milk. The recipe yields the equivalent of one 12-ounce can so it needs to be doubled for this recipe.
Vegan Cream of Chicken Substitute – I use my own recipe for Vegan Cream of Chicken Substitute. It yields the equivalent of one can of cream of chicken soup so be sure to double it to get the 20 ounces needed for this recipe.

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

How to Make Easy Cheesy Tetrazzini:

STEP ONE: Preheat the oven to 350°F. Spray a 9×13-inch baking dish with non-stick cooking spray.

STEP TWO: Cook spaghetti according to package directions. Rinse with cold water, drain, and return to the cooking pot.

STEP THREE: Into a large saucepan over medium-high heat, add the butter. When the butter is melted, add the onion and mushrooms. Cook, stirring frequently for 3 minutes, until softened. Add the 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

STEP FOUR: Pour the sauce over the spaghetti. Toss to evenly distribute the sauce throughout. The mixture will be very soupy. Transfer the pasta to the prepared 9×13-inch baking dish. Sprinkle Colby-Jack cheese over the top.

STEP FIVE: Bake, uncovered for 40 minutes then serve hot.
