Ingredients

Vegetables

  • 2 cups cauliflower florets
  • 2 cups butternut squash, cubed
  • 1/2 cup diced red onions

Cheese and Seasonings

  • 1 cup parmesan cheese, grated
  • 1 tsp sea salt
  • 1 tsp black pepper
  • Aged cheddar cheese, for topping (about 1 to 1 1/2 cups, shredded)

Other

  • 1 can (10.5 oz) celery soup

Instructions

  1. Prepare the Vegetables: In a large bowl, combine 2 cups of cauliflower florets, 2 cups of cubed butternut squash, and 1/2 cup of diced red onions. Ensure the vegetables are cleaned and prepped for mixing.
  2. Add Cheese and Seasonings: Add 1 cup of grated parmesan cheese into the bowl. Season the mixture with 1 teaspoon of sea salt and 1 teaspoon of black pepper, adjusting to your taste preferences.
  3. Mix and Combine: Pour in 1 can of celery soup to the vegetable and cheese mixture. Mix all the ingredients thoroughly until everything is evenly coated and well combined.
  4. Assemble the Casserole: Transfer the mixture into a square baking dish, spreading it out evenly. Then, top with a generous layer of aged cheddar cheese according to your liking.
  5. Bake the Casserole: Preheat your oven to 375°F (190°C). Place the baking dish in the oven and bake for approximately 25 minutes, or until the cheese is melted, bubbly, and the vegetables are tender when pierced with a fork.
  6. Serve and Enjoy: Remove the casserole carefully from the oven. Let it cool for a few minutes to set before serving. Enjoy your warm, cheesy butternut squash casserole as a delicious side or vegetarian main dish.

Notes

  • You can substitute the celery soup with a homemade cream of celery sauce for a fresher taste.
  • To add a crunchy texture, sprinkle some breadcrumbs on top before adding the cheddar cheese.
  • For a vegan version, replace parmesan and cheddar with plant-based cheese alternatives and use a dairy-free cream soup.
  • Ensure vegetables are cut uniformly to promote even cooking.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
