Amazing Garlic Herb Butternut Squash Casserole Recipe FAQs
How do I choose the perfect butternut squash?
Absolutely! Look for a butternut squash that feels heavy for its size, has a smooth, tan skin, and is free of dark spots or blemishes. A good squash should yield slightly to pressure when pressed, indicating ripeness and tenderness.
What is the best way to store leftovers?
Store the casserole in an airtight container in the refrigerator for up to 3-4 days. If you want to keep it even longer, I recommend portioning it out into smaller containers to make reheating easier. Just pop it back in the oven at 350°F (175°C) for the best texture!
Can I freeze this casserole?
Yes, you can! To freeze the Amazing Garlic Herb Butternut Squash Casserole, wrap it tightly in plastic wrap, followed by foil to prevent freezer burn. It can be frozen for up to 3 months. When you’re ready to bake, just pop it in the oven from frozen and add around 20–30 extra minutes to your baking time.
My casserole looks a bit watery, what can I do?
If your casserole is watery, it might be due to excess moisture in the squash or broth. Next time, make sure to roast the squash until it’s just caramelized and reduce the amount of broth slightly. If it still needs fixing, you can sprinkle some additional breadcrumbs on top about halfway through baking to soak up some of that excess moisture!
Are there any common allergens in this recipe?
The Amazing Garlic Herb Butternut Squash Casserole is naturally vegetarian and gluten-free if you use gluten-free breadcrumbs. However, it does contain dairy if you decide to add Parmesan cheese, which is something to keep in mind if you’re catering to lactose-intolerant guests. For a vegan alternative, you can substitute the cheese with nutritional yeast or a vegan cheese option.
Can I make this dish in advance?
Very! You can assemble the casserole ahead of time and store it covered in the refrigerator for up to two days before baking. Just remember to add a bit of extra baking time if it’s coming straight from the fridge, as it will be colder than a room-temperature dish. It’s an excellent option for busy days or holiday feasts!
