Directions

Prep 15 minCook 30 min

1
Heat the oven to 350°F. Lightly coat a 9×13-inch baking dish with cooking spray.
2
Bring a large pot of salted water to a boil. Cook the penne until al dente (8–10 minutes), then drain well.
3
Meanwhile, warm the oil in a large skillet over medium heat. Add the sliced portobellos and cook, stirring occasionally, until they release their liquid and begin to brown, 5–7 minutes; transfer to a plate.
4
In the same pan, melt the butter over medium heat. Stir in the flour, garlic, and basil; cook 1–2 minutes to form a paste. Gradually whisk in the milk and cook, whisking, until smooth and thickened, 4–6 minutes. Off the heat, stir in half of the mozzarella until melted.
5
Squeeze the thawed spinach very dry. Add the cooked pasta, sautéed mushrooms, spinach, and soy sauce to the sauce and fold gently to coat.
6
Transfer to the prepared baking dish, sprinkle with the remaining mozzarella, and bake until bubbly and lightly browned, about 20 minutes. Let rest 5 minutes before serving.
