For the casserole:

For the topping:
- Aged cheddar cheese, shredded for easy melting (amount as desired)
- Prepare the Vegetables: In a large mixing bowl, combine 2 cups of cauliflower florets, 2 cups of cubed butternut squash, and 1/2 cup of diced red onions to create the vegetable base for your casserole.
- Add Cheese and Seasonings: To the bowl of vegetables, add 1 cup of freshly grated Parmesan cheese. Season with 1 teaspoon of sea salt and 1 teaspoon of black pepper, ensuring an even distribution for balanced flavor.
- Mix and Combine: Pour in 1 can of celery soup and thoroughly mix all ingredients until everything is evenly coated and well combined, forming a creamy vegetable mixture.
