Italian inspired food is an all-time family favorite.  It always makes me laugh a little when people comment that all we Southerners consume is comfort food. While we do know our way around the best of the best comfort foods, dishes like classic spaghetti, oven baked Italian sausage manicotti, cheesy chicken spaghetti and even spaghetti salad are beloved make no bones about it. Just like any other part of the country and world, it depends solely on the occasion and who will be eating with us that typically dictates what direction I go with the entrée at any meal that I serve.

  1. Why did no one catch that it says use a third of the meat sauce, repeat two more times, then asked for a fourth?

    1. You only use 1 cup of sauce as stated in the recipe, on the bottom of the slow cooker. Divide the remaining into thirds for the layers. Nothing was missed on our end.

  2. I don’t like sausage in my pasta. I know to add extra beef, but are there any other changes I should make?

    1. 5 stars
      That’s what I used. If you go by directions it turns out amazing!! I wouldn’t change a thing.
      I will be taking this to church tomorrow for our potluck…can’t wait.
      The sausage adds that little zip to the sauce and blends nicely. It doesn’t stand out. Worth adding it.

    1. You can. Typically cooking on high takes half the amount of time but, test it as slow cookers are just like ovens, and can vary wildly.

      1. I believe step #4 had a typo, where it says “…cook string…” Instead of ‘stiring’. 😊

  3. This looks fantastic. I’ve been wanting to try the “slow cook” function on my Instant Pot and this will be just the recipe I’ll try it with.
    Thanks for the great post!
