Caramelized Onion and Mushroom Stuffed Butternut Squash #SundaySupper

Today is Sunday Suppers 2nd Birthday. Sunday Supper is the brain child of Isabel Reis Laessig. It was Isabel’s dream to inspire bloggers to help bring families back together at the dinner table. I joined this amazing group a year and a half ago and have loved being inspired by my other fellow bloggers. We were told to share our favourite memory of Sunday Supper today. Mine is bitter sweet in a way because my fondest memories of the last year and a half were the two times I was actually able to participate in the live twitter chat. Because of the time difference here in the UK I can’t participate in the twitter chats so the few times I have been able to participate have been so fun. These bloggers are so fun to hang out with. If you haven’t joined them yet on Sunday nights for the twitter chats you need to. Until I joined this group I had never really gotten into using twitter, I didn’t really get it. But joining this fabulous group of bloggers I discovered how fun twitter can be as a platform to talk to people all around the world. Hopefully I will be able to join in on more chats in the future but until then I just enjoy the fellowship I get with this community through our blogs.

Caramelized Onion and Mushroom Stuffed Butternut Squash

2 medium sweet onions, sliced
(10 oz) mushrooms, sliced
3 Tbsp olive oil and more as needed
(1/4 c.) balsamic vinegar
1 medium size butternut squash
olive oil for drizzling
handful of chopped walnuts *optional

Turn oven onto 180C (350F) Cut the butternut squash in half and place in a roasting tin cut side up and drizzle some olive oil over them, sprinkle with some freshly cracked salt and pepper. Put in oven for 40 minutes.

While the butternut squash is roasting in a large sauce pan heat the olive oil medium high heat. Add the onions and mushrooms. Once the onions/mushrooms begin to brown, turn the heat down to medium. Stir often to prevent burning and reduce the heat if needed. Allow the onions to caramelized to a beautiful tan/brown colour, this could take up to 30 minutes.

Once the onions have started to caramelise deglaze the pan with the vinegar, stir the pan to make sure you pick up any browning bits stuck to the pan. Remove from heat.

Take the squash out of the oven and scoop out the middle, being careful as it will be hot.

Chop up the squash innards and toss with caramelized onions and mushrooms. Season to taste with salt, pepper and possibly more balsamic vinegar.

Full the butternut squash shells with the mixture and top with chopped nuts. Put back in the oven for 10-15 minutes until nuts are toasted.

    I love everything about this recipe, Laura! Lately we’ve been having roasted butternut pretty often but always as a side dish. I am pinning this on my Recipes to Try board because I think it deserves center stage the next time!

    I have yet to take part in a live Twitter chat because of the time difference but they always sounds like such fun. I must remedy that when I am home this summer!
