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.

Refrigerate the remaining cashew cream for upto 4 days to use in other recipes or make cashew alfredo. Stove top: Cook the Spaghetti according to instructions on the package.
