Description

This Easy Butternut Squash Casserole combines tender butternut squash and cauliflower, creamy celery soup, and melty cheese for a comforting, flavorful side dish that’s perfect for fall dinners or anytime comfort food is calling.


Ingredients

  • 2 cups cauliflower florets
  • 2 cups butternut squash, cubed
  • 1/2 cup diced red onion
  • 1 cup grated Parmesan cheese
  • 1 teaspoon sea salt
  • 1 teaspoon black pepper
  • 1 can (about 1011 oz) condensed cream of celery soup
  • 1 cup aged cheddar cheese, shredded (for topping)

Instructions

  1. Preheat the oven to 375°F (190°C).
  2. In a large bowl, combine cauliflower, butternut squash, and red onion.
  3. Stir in Parmesan cheese, salt, and pepper until the vegetables are evenly coated.
  4. Mix in the cream of celery soup until everything is well combined.
  5. Transfer the mixture into a baking dish and spread it out evenly.
  6. Sprinkle the top with shredded aged cheddar cheese.
  7. Bake uncovered for about 25 minutes, until the cheese is melted, bubbly, and the vegetables are tender.
  8. Let it cool slightly before serving. Enjoy warm.

Notes

  • Substitute butternut squash with sweet potatoes or pumpkin—adjust cooking time until tender.
  • Make it dairy-free with 3/4 cup nutritional yeast and a plant-based cheese alternative.
  • Use mushroom soup or homemade cashew cream (from blended soaked cashews and broth) instead of celery soup.
  • Add a crunchy topping of breadcrumbs or crushed nuts for texture contrast.
  • Sprinkle in cayenne or smoked paprika for a spicy kick.
