Ingredients Needed
- Bacon – Sub maple or thick cut bacon if desired.
- Onion – Use a sweet, Vidalia, or white onion for this recipe.
- Garlic – You can substitute garlic powder or leave it out all together.
- Spices – Use thyme, rubbed sage, salt, and pepper.
- Kale – This is hearty but you can also substitute Swiss chard, beet greens, or spinach.
- Butter – I recommend using unsalted butter as opposed to salted butter.
- Butternut squash – I like to use the prepped squash in the produce department. You can also substitute sweet potato or yams.
- Panko bread crumbs – Panko can be replaced with crushed Ritz crackers for a more buttery flavor.
- Parmesan cheese – This cheese can be swapped with any other cheese blend, for a melty topping.

How to Make Butternut Squash Casserole
- Preheat oven to 375F. Cook bacon in a large dutch oven over medium heat. Remove and drain on paper towels.
- Add your diced onion, garlic, thyme, and sage to the leftover bacon fat and cook until tender. Add in your kale and cook for 5 minutes or until the kale is slightly wilted. Remove the kale and onion mixture and place it in a large bowl.
- Add butter and butternut squash cubes to pot. Cook on the medium high heat for 5 minutes until it is slightly brown on the outside and starting to get tender.
- Remove the squash mixture and add to the kale. Toss together to combine, cooking until the kale starts to wilt.
- Place in 9×13 prepared casserole dish, cover with foil and bake 20-30 minutes or until the squash is tender. While the casserole is baking, make breadcrumb topping.
- Once your squash is tender, remove the foil and coat the top of the casserole with the bread crumb mixture. Bake for another 5 to 15 minutes or until toasted and golden brown. Remove from the oven and cover with your cooked bacon.

How long does it last?
Leftovers will last 3-4 days in the fridge in an airtight container. Reheat in the oven at 375 degrees F, and follow the baking notes provided in the instructions.
I also recommend waiting to top with panko if you plan on refrigerating this casserole, to make sure you get the crispiest topping possible!
Can I freeze it?
Yes, this casserole freezes for up to 2 months like this million dollar chicken casserole! Serve whenever you need a quick meal for a weeknight or just want something savory and easy to make. Perfect for when you are prepping for Christmas dinner early.
Pro tip – allow your casserole to thaw until the next day before you put it in the oven after freezing, to help speed up cooking time.
If you prefer to skip the thaw, place in the oven and cook for close to an hour or until hot throughout. Top with breadcrumbs and serve!
Serving Suggestions
Since this is more of a comforting food, we recommend serving it with side dishes that are lighter, such as a brussels sprouts salad or a side salad with a vinaigrette dressing.
You can also add something more filling such as biscuits or turkey, to help create a well rounded dinner plate for your family. This is great with a butternut squash soup!
Tips for the Best Casserole
- Prepped (cleaned and diced) squash is a time saver!
- Use cooking spray or olive oil to keep your butternut squash casserole from sticking to the baking dish.
- Chop your onions, squash, thyme, garlic, and kale the day before and place in airtight containers in the fridge to save on prep time. Use a food processor for less mess.
- Use fresh breadcrumbs toasted on a baking sheet with butter for a richer flavor.
- For a heartier version, mix in some cooked sweet Italian sausage.
- Mix the melted butter and bread crumbs in a small bowl before sprinkling on casserole.
- You can use canned pumpkin, sweet potatoes, or carrots instead of butternut squash.
- Store leftovers in a container with a tight-fitting lid. In the fridge will last about 5 days.
- To make leftovers last longer, wrap the casserole up and store in the freezer. They will last 3 months.
