The Story

I’ve officially embraced it: summer is over. And honestly, I love this time of year — crisp mornings, open windows, leaves slowly unraveling their color, pumpkin patches, and couch cuddling under a blanket. But I wasn’t ready for it this time. Life’s been good busy, but still…busy.

I tried to force the transition — a few PSLs, a scarf or two — but the fall feeling just wasn’t there. Until I made this. Because if there’s one thing that can ease me into the season, it’s autumn food. Roasted roots. Soups and chilis. Squash and pumpkin everything. When the kitchen smells like warm spices and comfort, I remember exactly why I love this season.

Ingredients

• 3 cups butternut squash, cut into bite-size pieces
• 2 tbsp grape seed or neutral oil, divided
• 3/4 cup quinoa
• 1½ cups vegetable broth
• 1/2 medium yellow onion, thinly sliced
• 2 cloves garlic, minced
• 8 oz cremini, button or baby Bella mushrooms, quartered
• 1/2 cup walnuts, roughly chopped
• 3 cups kale, loosely packed & chopped
• 1/3 cup parmesan cheese (or vegan parm), divided
• sea salt and black pepper, to taste

Instructions

• Lightly grease an 8×8-inch (or comparable size) baking dish and preheat oven to 400°.

Butternut Squash

• Line a baking sheet with parchment paper. Add cubed butternut squash and toss with 1 tablespoon oil. Season with a healthy pinch of salt and pepper. Bake at 400 F for 15-20 minutes until fork tender. Remove from oven and set aside.

Quinoa

• While the squash is baking, rinse quinoa in a mesh strainer. Add to small saucepan with vegetable broth and bring to a boil over high heat. Reduce heat to low, cover and cook until liquid is fully absorbed and quinoa is fork-tender (15-20 minutes). Once quinoa is finished cooking, season with a healthy pinch of salt and pepper and half of the vegan Parmesan cheese. Stir, sample and adjust seasonings to taste. Remove from heat and leave covered.

Onions, Mushrooms & Kale

• Heat large skillet over medium heat. Add remaining 1 tablespoon oil, onion and garlic. Season with a pinch each of salt and pepper. Cook until onion is translucent (about 4 – 5 minutes) stirring frequently. Add mushrooms and walnuts and season once more with salt and pepper. Continue cooking for 5 minutes or until mushrooms are lightly browned.
• Make room in the pan and add kale. Season once more with a good pinch of salt and pepper and stir to coat. Cook until kale is just tender (about 3 – 5 minutes). Remove from heat and set aside.

Assemble and Bake

• Reduce oven temperature to 375 F and add cooked quinoa to prepared baking dish. Top with vegetable-walnut mixture and roasted butternut squash. Lightly stir to combine. Top with remaining vegan Parmesan cheese and bake uncovered for 10 minutes to warm through. Serve immediately. Leftovers will keep covered for up to 3 days.
