  1. Since subscribing to your blog, I have tried many of your Instant pot recipes and I must say I have not been disappointed at all. I have yet to try any of these pasta dishes but will definitely do so. Thank you so much for all your recipes.

    1. Hi Freny – So happy that you have been enjoying the recipes on the blog. I would love to hear how it turns out when you try the next pasta recipe.

  2. Hi Meeta,
    Love all of your recipes. thank you for all of your hard work.
    my issue with pasta in IP is that they become dry after 10-15 minutes. i do quick pressure release but if we’re having dinner then i’ll serve first batch and leave rest in the pot and by the time i get to the next serving they are already dry like no sauce.

    1. Hi Mona – Thank you for the feedback. You can add a little extra broth or water when cooking the pasta. Also, it could help to take the steel insert out of the instant pot, so there is less heat around the pasta, and it wont dry as quickly.

  3. I have made the mushroom and the lo mein. Next on the list is the lemon asparagus. All these yummy recipes make it hard to cut down the carbs!
