Instant Pot Mushroom Tetrazzini Simple Creamy Comforting Spaghetti Pasta dinner with simple pantry ingredients. 1 Pot Tetrazzini. Vegan Soyfree Recipe. Can be nutfree, Glutenfree, Oilfree. Jump to Recipe
Simple Creamy Comforting Pasta dinner with simple pantry ingredients. Ready within minutes! The sauce is like bechamel sauce with a roux. I use cashew cream for a cheesy creamy thickness. Usually you would cook the noodles separately, cook the mushrooms, veggies or meat, then mix the lot, top with cheese and breadcrumbs and bake. That’s a lot of dishes and time! This tetrazzini gets made in the Instant pot Pressure Cooker.
Saute the mushrooms, then roast the flour for a roux, add broth and noodles and close the lid. Meanwhile, prep your garnishes and dinner is ready. I like to add toasted breadcrumb topping to the dish as the texture and flavor makes it feel like it is a baked dish that has hours put into it :). You can use any other toppings of choice,some vegan parm, vegan cheese (add when hot so it melts), fresh herbs, black pepper or pepper flakes.
I have not tried gf pasta in Instant Pot. Use stove top method for gluten-free. Easily nutfree, oilfree

Tips to Cook Pasta in Instant Pot
Pasta in the Instant pot/pressure cooker can be very iffy. It can get overcooked, undercooked, stick to each other, stick to the bottom and cause burn message and what not.
- Add a bit more liquid than you think is enough. This allows for pasta to breathe while cooking and reducing chances of sticking to each other and the bottom.
- Pressure Cook the pasta to the lower amount of half the cooking time listed on the pasta package. (eg. 4 mins for 8 to 11 mins range)
- Quick release or release within a few mins and give it the pasta a good mix immediately to separate the noodles. You also want to remove the pasta from the Instant Pot soon. The Pot remains hot for a while and will keep cooking the pasta.
- Pasta brands can differ in cooking times, so if your noodles are overcooking, reduce cook time by 1 min, and if not cooking evenly, increase time by a min.
- When doubling, add about 1.75 times the water and add a minute to the pressure cooking time.
