Ingredients You’ll Need
Gathering simple, fresh ingredients is key to making a casserole this delicious. Each component plays a special role, adding unique flavors, textures, and colors that marry beautifully when baked.
- 2 cups of cauliflower cloves: Provides a tender, slightly nutty base that complements butternut squash perfectly.
- 2 cups of butternut squash (cubed): Adds a naturally sweet, creamy texture with vibrant orange color.
- 1/2 cup of diced red onions: Brings a subtle sharpness and depth of flavor when baked.
- 1 cup of parmesan cheese: Offers a salty, umami boost to elevate every bite.
- 1 tsp sea salt: Enhances all the natural flavors without overpowering.
- 1 tsp black pepper: Adds just the right amount of heat and spice.
- 1 can of celery soup: Acts as the creamy binder that keeps the casserole moist and luscious.
- Aged cheddar cheese: Sprinkle on top for a golden, melty, rich crust that’s irresistible.
How to Make Easy Butternut Squash Casserole Recipe
Step 1: Prepare the Vegetables
Start by preheating your oven to 375°F (190°C). While it warms, chop the cauliflower into small florets and peel and cube the butternut squash. Dice the red onions finely. These fresh vegetables are the foundation of your casserole, so taking your time here ensures wonderful texture and flavor in every bite.
Step 2: Mix the Base
In a large bowl, combine the cauliflower, butternut squash, and diced onions. Add the can of celery soup, sea salt, black pepper, and parmesan cheese. Gently fold everything together so the vegetables are evenly coated in the creamy soup and cheesy goodness. This mix is where the magic begins, building layers of flavor and creating a cohesive casserole filling.
Step 3: Assemble and Bake
Transfer your mixture into a greased baking dish, spreading it evenly. Generously top with shredded aged cheddar cheese to create that golden crust we all love. Place the dish in your preheated oven and bake for about 30-35 minutes, or until the cheese is bubbly and browned, and the vegetables are tender when pierced with a fork.
How to Serve Easy Butternut Squash Casserole Recipe
Garnishes
Sprinkle freshly chopped parsley or chives on top just before serving to add a fresh, bright note that contrasts beautifully with the rich cheese and squash. A light drizzle of browned butter can also enhance the nutty flavors if you’re feeling indulgent.
Side Dishes
This casserole pairs wonderfully with crisp green salads, roasted meats like turkey or chicken, or even a simple crusty bread to mop up every last bit. It’s flexible enough to be the star or a comforting side, fitting into many meal plans.
Creative Ways to Present
For a festive touch, serve the casserole in individual ramekins for personalized portions. You can also layer it with caramelized onions or add toasted pecans on top for an unexpected crunch and sweetness that brightens the dish.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer leftovers to an airtight container and store in the refrigerator for up to 3 days. The flavors actually meld and improve, making it an excellent next-day meal option.
Freezing
This casserole freezes beautifully. Portion it into freezer-safe containers before baking or freeze after baking once fully cooled. Either way, it can be kept for up to 2 months. Just thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers in the oven at 350°F (175°C) covered with foil to prevent drying out, for about 15-20 minutes until warmed through, or microwave individual portions for a quicker fix with slightly less crispy topping.
FAQs

Consider mixing in cooked quinoa, cooked chicken, or cooked sausage for added protein and heartiness without sacrificing flavor.
