Ingredients

  • 2 lb zucchini sliced
  • kosher salt and ground pepper to taste
  • 3 tbsp olive oil divided
  • 1 onion grated
  • 3-4 garlic cloves minced
  • 1 cup almond milk or 2% milk
  • 1 1/2 tbsp cornstarch
  • ½ tsp oregano
  • 1/4 cup finely grated parmesan cheese
  • 1/2 cup cheddar cheese
  • 1/4 cup seasoned bread crumbs

Instructions

  • Preheat the oven to 425F.
  • Place the sliced zucchini in an oven-safe dish and season with salt and pepper.
  • Drizzle with 2 tablespoons of oil and toss well with your clean hands. Bake for 10-12 minutes, or until the zucchini slightly softens.
  • Heat the remaining tablespoon of oil in a medium saucepan over medium heat. Sauté the onion and garlic for 2-3 minutes.
  • Meanwhile, in a small bowl whisk the almond milk with cornstarch and oregano.
  • Pour the milk mixture into the saucepan and simmer, stirring frequently for 3-4 minutes, or until sauce thickens to coat the back of the spoon. Stir in the parmesan cheese.
  • Remove the baking dish with the roasted zucchini from the oven. Drizzle with the garlic-parmesan sauce.
  • Sprinkle with cheese and breadcrumbs. Bake for 35-40 minutes or until squash is tender.
  • Serve and enjoy.

Notes
