Try this mushroom leek kale spaghetti squash for a vegan main served with a mixed greens salad or as simple side for a weeknight dinner or even a big holiday meal.
Who knew hitting the jackpot could be finding a spaghetti squash in my CSA last week.
It’s the little things, right?
Throwing gratitude into the air even for what one person might consider insignificant doesn’t take much effort.
And I hope this kind of easy breezy positivity is contagious. That might be the only bug I want to catch these days!
Last month I made healthy roasted tomato spinach spaghetti squash.
Ever since it’s been on my list to share another recipe with this incredibly versatile vegetable: mushroom leek kale spaghetti squash.
Mushrooms and leeks go so well together, and kale is a welcome addition.
I like including nutritious greens whenever I can. It’s not difficult because they work in lots of cold weather meals like soups and sauteed vegetable dishes.
How To Make Mushroom Leek Kale Spaghetti Squash
First, I bake the spaghetti squash in the oven. You absolutely can do this in advance to save time.
The halved spaghetti squash takes about 40 minutes to roast. If you plan to bake it ahead of time, use a fork to comb the flesh from the skin, let it cool down and then store it in an airtight container for up to 1-2 days.
In a skillet on the stove, I heat olive oil and sauté the leeks. Once the leeks start to soften, I add sliced cremini mushrooms.
When the mushrooms have caramelized, I stir in minced garlic.
Then I add chopped curly kale and watch the greens wilt.
After that I fold the spaghetti squash into the mushrooms and greens in the skillet.
In addition to salt and pepper for seasoning, I use nutritional yeast, a common vegan substitute for Parmesan.
Nutritional yeast melds right into the spaghetti squash adding wonderfully cheesy flavor.
To finish, I mix in chopped toasted walnuts and parsley.
Try Spaghetti Squash as a Vegan Main or Side
Especially during the fall and winter months, I am on a constant hunt for nutritious comfort food.
I like serving mushroom leek kale spaghetti squash as a main with a salad. It is a different option than soup with that same warm, cozy and comforting bite.
Spaghetti squash also makes a great side, too. With mushrooms and leeks, it would fit right in with a holiday meal like Thanksgiving.
