Ingredients
Scale
Vegetables
- 2 cups cauliflower florets
- 2 cups butternut squash, cubed
- 1/2 cup diced red onions
Dairy & Cheese
- 1 cup parmesan cheese
- Aged cheddar cheese, for topping (about 1 cup shredded)
Pantry
- 1 tsp sea salt
- 1 tsp black pepper
- 1 can cream of celery soup (approx. 10.5 oz)
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole.
- Prepare Vegetables: Steam or boil the cauliflower florets and butternut squash cubes until they are tender but not mushy, about 8-10 minutes. Drain and set aside.
- Sauté Onions: In a skillet over medium heat, lightly sauté the diced red onions until they are soft and translucent, approximately 3-4 minutes.
- Combine Ingredients: In a large mixing bowl, combine the cooked cauliflower, butternut squash, sautéed onions, cream of celery soup, sea salt, black pepper, and parmesan cheese. Mix well until all ingredients are evenly incorporated.
- Assemble Casserole: Transfer the mixture to a greased baking dish, spreading it out evenly. Sprinkle the top generously with shredded aged cheddar cheese.
- Bake: Place the casserole in the preheated oven and bake for 20-25 minutes or until the cheese is melted and bubbly, and the top is lightly golden brown.
- Cool & Serve: Allow the casserole to cool for 5 minutes before serving to let it set and enhance flavors.
Notes
- You can substitute cream of celery soup with cream of mushroom or cream of chicken soup for variation.
- For a richer flavor, use fresh grated cheeses instead of pre-shredded cheese.
- This casseroles pairs well with roasted meats or as a vegetarian main when served with a side salad.
- Leftovers can be refrigerated for up to 3 days and reheated in the oven for best results.
