I ate classic turkey tetrazzini quite a bit as a child- its one of my dad’s favorites! As an adult, I’ve skipped the meat in this version but still kept a lot of the classic flavors and tastes of the traditional version.

This mushroom tetrazzini is a delicious vegan comfort food recipe. A creamy, hearty, flavorful bowl of veggie pasta?  Sign me up!

What’s In This Mushroom Tetrazzini?

• Pasta of choice: I used spaghetti because we had a ton on hand and I love dragging a forkful of twirled pasta through the creamy mushroom sauce – but use any pasta shape you like! Egg noodles would also be delicious.
• Olive oil: for sauteing the vegetables
• Onion and garlic: for flavor, I always load aliums in my pasta dishes because #yum
• Mushrooms: I used crimini because thats what we had on hand (and my grocery delivery service sent me about 5x the amount of mushrooms I ordered! Not mad at all about that mix up). You can use any variety you’d like.
• Butter and Flour: to make a roux to thicken the sauce. This is something I don’t do often enough – these 2 ingredients make a world of difference and turn a thin sauce into something amazing!
• Unsweetened almond milk, or any milk of your choice.
• Greek Yogurt, dairy free, plain unsweetened. You can use cashew cream too. I’m amazed by all the great vegan dairy substitutes nowadays.
• Chopped parsley, to give the dish a fresh flavor
• Breadcrumbs for the topping: use gluten-free if you are avoiding wheat… or panko if you aren’t, the crunch is excellent!

How Do I Make Mushroom Tetrazzini?

Dietary Modifications

While this is vegan, you can totally use a regular unsweetened dairy yogurt if you eat dairy.

And if you are gluten-free, just make sure you use a gluten free pasta choice, and make sure to check those breadcrumbs too.  Also use a almond or coconut flour instead of the regular all purpose for the roux!
