Preheat the oven to 400°F. Line a baking sheet with parchment paper and set aside.
Cut the delicata squashes in half lengthwise and scoop out the stringy insides and seeds. Save to roast separately!
2 small delicata squashes
Brush the inside of the squash with olive oil and sprinkle lightly with sea salt.
2 tablespoons olive oil
Place the squash cut side down on the baking sheet and bake for 30 to 40 minutes, or until a knife easily pierces the squash.
While the squash bakes, prepare the filling. Start by making the cashew cream sauce: blend the cashews, water, nutritional yeast, garlic, lemon juice, and salt in a high-powered blender until completely smooth, about three minutes, and set it aside while you prepare the spinach and white beans.
½ cup raw cashews, ½ cup water, 2 tablespoons nutritional yeast, 1 garlic clove, 2 tablespoons fresh lemon juice, 1 teaspoon sea salt
To make the filling, heat one tablespoon of olive oil in a medium-sized deep-sided saute pan over medium heat. Once hot, add the diced onions and cook for about 5 minutes, until translucent. Add the garlic and saute until fragrant, about 1 to 2 minutes.
1 small white or yellow onion, 3 garlic cloves
Add in the spinach and white beans, and cook until the spinach is wilted and the beans are warmed through. Pour in the cashew cream sauce and mix until fully combined, letting the sauce thicken slightly as it mixes with the vegetables. Taste, and add salt and pepper as needed.
1½ cups (15 oz. can) white beans, 4 cups fresh spinach, Salt & pepper
Divide the creamed spinach filling into the roasted squash halves. Top with toasted breadcrumbs, if using (breadcrumb how-to in the Notes below). Return to the oven for five minutes to warm it all through and serve immediately.
