- Egg: helps bind the mixture together. Leave out for dietary needs if desired
- Almond Milk: regular skim milk, soy milk or coconut milk can be used instead
- Brown Sugar: adds sweetness. Sub with maple syrup if desired
- Melted Butter: alternative options are coconut oil or margarine
- Spices: Add a festive flavor, feel free to adjust to your liking

Combine the butternut squash, eggs, milk, sugar, butter, vanilla and spices in 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!
Frequently Asked Questions:
Can I Use Frozen Butternut Squash?
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.
How Can I Make This Recipe Allergy Friendly?
To make this a gluten free butternut squash casserole, use gluten free oatmeal . Double check the ingredient list on all the other ingredients, however most of them should already be gluten free!
To make this a dairy free butternut squash casserole, replace the butter with coconut oil. Always check your other ingredients to make sure they don’t have dairy hidden in the ingredients!
Tips for Success:
- 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.
