Instant Pot Stuffed Shells

If you like pasta, this is the dish for you! A combination of shells, spinach and cheese, what could be better?

Anyway, it’s a great option for meatless Monday or anytime you like a vegetarian dinner.

You can make in your Instant Pot or any other pressure cooker in 25 minutes.

For the marinara sauce , you can make it yourself or just use store-bought.

Can I use a different sauce?

Yes! Feel free to replace the marinara sauce with pesto, meat sauce or anyone you like.

I’m doing it always when I want to diversify without getting bored of this recipe.

Do you have more one-pot meals options?

Sure! Try this vegetarian lasagna, this chicken alfredo or this spaghetti bolognese.

  1. I’m seeing comments about a BURN notice and the FB post where I found the recipe references BURN notices. Anyway to avoid this error message?

  2. Could I make this with an Alfredo based sauce or would it be too thick? Would the shells stick to the bottom without a thick layer of meat sauce to place the shells on top of?

    1. Its up to your choice to use the Alfredo sauce instead of marinara sauce. But definitely it would be a new taste.

  3. I got the BURN NOTICE too. GRRRRR. I wish the author would have addressed this.
    How frustrating. I should have listened to the posts.

  4. I am a new owner of the 1.5L cooker and I have a lot of difficulty resizing recipes for the smaller pot. I’m not to good at converting liters to cups.
