Ingredients You Need for Butternut Squash, Portobello, and Spinach Casserole With Sausage [Vegan]

1 medium butternut squash (around 2.5 lbs), peeled and diced into 1″ cubes
4 Tablespoons extra virgin olive oil, divided
2 links of vegan sausage
3 leeks, white and pale green parts only, washed and cut into thin half-moon slices
2 large cloves of garlic, minced
1 8 oz package of Cremini mushrooms, thinly sliced
2 cups Portobello mushroom soup
1/2 cup vegetable stock
1 teaspoon white miso
2 Tablespoons nutritional yeast
1/4 cup finely chopped fresh sage
1 Tablespoon finely chopped fresh rosemary
1 9 oz bag of baby spinach
Kosher salt and black pepper, to taste
3 cups cooked pearl barley (about 1 cup dry cooked per package directions)
2 Tablespoons fresh parsley, finely chopped

How to Prepare Butternut Squash, Portobello, and Spinach Casserole With Sausage [Vegan]

Preheat oven to 375 degrees.
In a large bowl, toss the diced butternut squash with 2 Tablespoons of olive oil and a pinch of kosher salt and a few grinds of black pepper. Once combined, spread the squash out evenly on a large rimmed baking sheet lined with parchment paper. Place in oven and bake for approximately 30 minutes, or until fork tender. Remove from oven and set aside. Leave oven on, but reduce heat to 350 degrees.
Remove Field Roast sausage links from packaging and place in a food processor. Pulse until the sausage resembles ground sausage.
In a large nonstick pan, heat 1 Tablespoon of olive oil over medium high heat. Add sausage and cook until sausage is browned and slightly crispy. Remove from pan and place on a paper towel lined plate. Set aside.
In the same nonstick pan, add an additional 1 Tablespoon of olive oil over medium high heat. Add the leeks and garlic and cook, stirring frequently, until leeks are tender, about 5-7 minutes. Add the sliced mushrooms, sage, and rosemary and cook an additional 3-4 minutes. Add the mushroom soup, vegetable stock, nutritional yeast, and miso. Stir until miso and nutritional yeast have dissolved into the liquid and everything is combined. Bring to a boil and then immediately reduce heat to low and simmer for 1-2 minutes. Add the fresh spinach and stir until spinach is completely wilted into mushroom mixture. Season to taste with salt and pepper, and remove from heat.
Grease a 9×13″ oven safe casserole dish with nonstick spray. In the dish, gently combine the cooked butternut squash, browned ground sausage, cooked barley, and mushroom mixture with a rubber spatula. Once combined, spread the mixture evenly throughout the baking dish. Place in the oven and cook, uncovered, for 35-40 minutes, or until most of the liquid has evaporated and top is evenly golden brown. Remove from oven and top with fresh chopped parsley. Let sit for 10 minutes before serving.
