Vegan Leek and Mushroom Fettuccine With a White Sauce

Growing up as a vegetarian, we typically consumed a lot of dairy. Cheese, yoghurt, milk, cream you name it!

Since becoming a vegan, however, I’ve wanted to recreate some dishes that would always call for dairy but now isn’t an option for me. One of my favourite ways to enjoy pasta was with a leek and mushroom white sauce.

I must say though, since creating this vegan version, I much prefer this! It tastes amazing, and you don’t even realise that there’s no dairy in it.

Sometimes it’s okay to indulge in comfort food

I don’t eat pasta often as it’s very much a “sometimes food” in our house but when I do, I enjoy it wholeheartedly. I used to always feel guilty for eating things that aren’t “technically” good for you but having a balanced diet is more important than stressing about it.

Stress does more damage to your body than eating things that aren’t the healthiest. Sometimes you just need to let it go and enjoy.

I find that as soon as I let go of this stress, my digestion also works better. We’re not meant to be eating when our bodies are in a stressed state of being.

Our stomachs close up, and the food doesn’t get digested well. You are only meant to be stressed for a short period and shouldn’t be consuming food when you are.

Think about it. When we were cavemen, we were only stressed when we were running from a bear or a lion. Your body isn’t meant to sustain that feeling for more than let’s say 10 minutes. And you certainly aren’t eating when you’re running for your life!

So, put things into perspective and give yourself that food that sometimes you feel guilty about ๐Ÿ™‚

  1. I love it. This pasta is amazing and it tasted like carbonara pasta. Easy and quick recipe.
    Thanks for sharing!

  2. Hello,

    This is indeed a great recipe! Thank you for sharing! Delicious and simple!

    With metta,

  3. This recipe is amazing! Thank you! It is a one that is definitely better than the ‘real thing’ (aka dairy cream). And less sickening to the stomach than a traditional creamy pasta. My non vegan and non friends LOVED it! I am actually about to make it again tonight.
    This time I am soaking the cashews for a few hours before blending for a creamier and quick assemble ๐Ÿ™‚ (I blended on and off for 20 mins so it wasn’t ‘grainy’)
    Thanks again and kind regards xx

    1. Hi Kirra,

      LOVE to hear when non vegans love a traditional meal that has been adapted ๐Ÿ™‚

      Thanks for the feedback. I sometimes forget that not everyone has a high speed blender like me that turns everything into a super creamy, smooth consistency. I will add that to the steps to let people know! ๐Ÿ™‚
