Combine the butternut squash, eggs, milk, sugar, butter, vanilla, and spices in a bowl. Mix until combined.
I recommend using a food processor or electric mixer to make it evenly blended and smooth. If you prefer a less smooth texture, however, mix with a fork! Pour the mixture into a greased pan.
Prepare the topping. Feel free to double the topping if you want extra. Make the oat flour (I make this by putting gluten-free oatmeal in a food processor/blender and blending until smooth). Combine it with the syrup, chopped pecans, and butter. Spread over the casserole and bake!
Store this butternut squash casserole in the refrigerator for up to 3 days. To help keep the casserole safe to eat, make sure to refrigerate the casserole within 2 hours and split it into shallow pans for quick cooling. More info on how to safely store leftovers here!

Frequently Asked Questions
Yes! This is a great time-saving tip! Frozen butternut squash cubes can be found in the freezer aisle of most grocery stores. Look for cubes that are already cut up and cooked. Typically, about 1.5-1.75 pounds of frozen butternut squash is equal to a 2-pound whole butternut squash. Warm the cubes in the microwave and then follow the recipe as normal.
Gluten-Free Casserole: use gluten free oatmeal. Double check the ingredient list on all the other ingredients, however, most of them should already be gluten-free!
Dairy Free Casserole: replace the butter with coconut oil. Always check your other ingredients to make sure they don’t have dairy hidden in the ingredients!
- Cook the butternut squash until completely tender. If not cooked long enough, the casserole will not be very creamy.
- Store in a covered dish in the refrigerator for up to 5 days. Reheat in the microwave. Add a dash of butter when reheating to enhance the flavor.
- Save a few pecans out and add to the topping prior to cooking. This helps add a nice garnish.
This dish is considered a healthy (light) version of butternut casserole. Here are a few things that make it healthy:
- Butternut squash is a main ingredient in the casserole. This orange veggie is packed with vitamins and minerals. It is particularly high in Vitamin A, Vitamin C, and potassium.
- Butternut squash is relatively low in calories. It offers a decent serving of fiber, which may help with your digestive tract.
- The casserole is topped with oatmeal and oat flour. This is another good source of fiber.
- The sugar in this dish has been decreased to only ¼ cup in the casserole and 2 tablespoon in the topping. It also uses maple syrup as a source of sweetener.
- There is no added cream and only a small amount of butter, which helps to keep it low in calories compared to your normal butternut squash casserole.
Looking to make this recipe even healthier than it already is? Here are some tips:
- Substitute the brown sugar that’s added to the casserole with a mashed banana. This will add a natural source of sweetener. Just make sure the banana is really ripe!
- Decrease the amount of oatmeal topping used to decrease calories. Cut the recipe in half and sprinkle it on evenly over the top of the casserole.
- Replace the butter with an alternative source of fat, such as coconut oil or olive oil.
