Creamy mushroom anything is a hit in our house. This pasta bake is no different and whenever I make it, I know there will be clean plates all around.

Oh wow! Not only was this easy to make but also very delicious!! I will be making this again.
I think I’ll add some onions (we love onions).
I did use gf Rice noodles and it still tasted very good!
Is the 500g of pasta the weight of the dry pasta before cooking, or should I cook less dry pasta to yield 500g of cooked pasta?
No, 500g dry uncooked pasta.
Hi Alida,
The recipe looks so delicious. I’m gonna cook for my family tomorrow. Was just wondering why sour cream is used. Any alternative if I have cooking cream, milk, cheese only?
It really just adds extra creaminess but it’s not a must. Just leave it out. 🙂
Absolutely delicious–half a recipe, except for cheese, because we are a small family. I used about 3/4 c of white cheddar. Someone added spinach and I think that’s a brilliant addition–will do it next time.
could I add spinach into the bake for cooking?
Absolutely! That would be delicious!
So yummy! really i like very much this recipe
What herb can be used instead of chives ?
Thyme, Parsley, sage or rosemary will all be delicious.
How much ML of milk/sour cream/cream did you use ?
1 cup = 250ml, so it’s 250ml cream and 250ml milk.
Absolutely delicious as the vegetarian main of our Sunday dinner and a great side dish for the meat eaters. Even my daughter who claims to hate mushrooms had two helpings. I made it with farfalle because everyone loves those bow ties. Thanks for a great recipe!
So happy to hear that. Love the idea of using bow ties!
Hi Alida,
Thanks for a good meal. I just made this for my wife and me and it was very welcome as the outside temperature is dropping toward 0 C. As ever with online and similar sourced recipes by good cooks, I doubled the preparation time. I’ve learned that my inexperience has consequences… I look forward to cooking this one again soon.
But in the meantime, perhaps a further sign of my inexperience, I’d find it so much easier if recipe writers would stick to one unit of quantity. Mixing grams, spoons, cups and pinches adds an unwelcome layer of confusion as I scrabble for conversion tables. Couldn’t we stick to grams?
I’m so glad you liked the recipe. I would love to have only one measurement on my blog but as I have a varied, international audience I am trying to cater to everyone’s needs.
Hi Ali, Making this one tonight as I have some leftover pasta from last nights dinner and some mushrooms waiting to be used before too long. I might even add some shredded cooked chicken and baby spinach as we LOVE our greens.
I agree with you re the various measurements for the global audience as much as I hated having to convert recipes, but now I have ALL measurement conversions printed out and stuck at arms length inside my pantry door – NO MORE ANSTIES. Yeah!
