Description

This cozy butternut squash and sausage casserole is a comforting and hearty meal perfect for fall and winter. It features roasted butternut squash, savory sausage, tender greens, and melty cheese all baked together in one delicious dish.


Ingredients

  • 4 cups butternut squash, peeled and cubed
  • 2 tbsp olive oil
  • Salt and black pepper, to taste
  • 1 lb Italian sausage (mild or spicy)
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 2 cups chopped kale or spinach
  • 1 cup cooked rice, farro, or quinoa (optional)
  • 4 large eggs
  • 1 cup milk or cream
  • 1 ½ cups shredded cheese (cheddar, mozzarella, or blend)
  • ¼ cup grated parmesan cheese (optional)
  • 1 tsp fresh thyme or chopped sage (optional)

Instructions

  1. Preheat oven to 400°F. Toss cubed butternut squash with olive oil, salt, and pepper. Spread on a baking sheet and roast for 25–30 minutes until tender and golden. Reduce oven temperature to 375°F.
  2. Meanwhile, cook sausage in a large skillet over medium heat, breaking it up as it browns. Drain excess fat if needed.
  3. Add chopped onion and garlic to the skillet. Cook until onion is soft, about 5 minutes.
  4. Stir in the chopped kale or spinach and cook until wilted. Remove from heat.
  5. In a large bowl, whisk together eggs, milk or cream, salt, pepper, and half of the shredded cheese.
  6. In a greased 9×13-inch baking dish, combine roasted squash, sausage mixture, and cooked grains (if using). Pour the egg mixture over and gently toss to combine.
  7. Top with remaining shredded cheese and parmesan (if using).
  8. Bake at 375°F for 25–30 minutes, or until the casserole is set and bubbling. Let rest for 5–10 minutes before serving.

Notes

  • Use store-bought pre-cut butternut squash to save time.
  • Add mushrooms or sweet potatoes for variation.
  • For vegetarian, substitute sausage with white beans or lentils.
  • Top with breadcrumbs or crushed crackers for added crunch.
