These overnight oats are packed with the calories, carbs, and protein you need to achieve healthy vegan weight gain!
What is the point of Overnight Oats?
Well first let me explain what overnight oats are.
Overnight night are where typically rolled oats have been soaked in a liquid (usually milk) overnight. The point of making your oat meal this way is it saves time!
With overnight oats, oatmeal is already ready in the morning to eat!
Pumpkin Spice Overnight Oats Ingredients
- Pumpkin Puree: One of the main ingredients,(NOT PUMPKIN PIE FILLING). You can make your own using this guide, How to Make Pumpkin Puree.
- Pumpkin Spice: Can't be a pumpkin spice recipe without pumpkin spice!
- Old Fashioned Oats: A Vegan With Curves pantry staple!
- Chia Seeds: These are really necessary for overnight oats as they absorb water making your oatmeal nice and thick. Plus chia seeds are vegan calorie dense foods and a great source of omega 3s!
- Plain Vegan Yogurt: This really helps balance out the taste of your pumpkin overnight oats.
- Maple Syrup: This sweetener pairs well with pumpkin flavor!
- Sea Moss Milk: My sea moss milk recipe has over 10 grams of protein per serving and is perfect for this recipe.
- Pea Protein: Typically I used hemp protein powder however, hemp protein powder is best paired with chocolate recipes. Caramel or vanilla pea protein powder pairs well with the pumpkin flavor.
Pea Protein Powder
In my Vegan Protein Powder for Weight Gain article (coming soon!), I list this brand here of pea protein powder as one of my favorite protein powders to use.
For this recipe it gives a nice flavor that pairs well with the pumpkin spice. You use hemp protein powder if you like but hemp protein powder will change the color of your oats. Typically I like hemp protein powder paired with chocolate flavors like in my chocolate cherry smoothie.
Can You Meal Prep these Overnight Oats?
Yes!
There are 2 ways meal prep and store this smoothie recipe:
Once a Week Meal Prep
Overnight oats can last in the refrigerator for up to 5 days. One of the best things you can do is get 4 to 5 mason jars and make individual portions once a week. And then each day add your desired toppings.
You can also make a big batch of these overnight oats in one large bowl, and then each morning for the week, portion them out into individual bowls and add your desired toppings.
Because these overnight oats are so easy to make, I do not recommend you freeze them. Freezing this recipe could change the texture of the oatmeal and honestly it is not worth it being that it takes only 5 minutes to put together.
So refrigerator storage is best.
Nightly Meal Prep
Overnight oats can also be prepped each night before you go to bed and then you add your desired toppings the next morning. This method might work best for your meal prep if you know you don't want to eat oatmeal every morning for the week.
Substitution, Cook, & Storage Tips
- Old fashioned oats is best for this recipe but you can also try it with instant oats. Keep in mind with instant oats, you will not have as much texture. Not suitable for steel cut oats.
- Vanilla flavored protein pairs best with this recipe. I use this brand of pea protein powder which can be ordered on amazon.
- Be sure to use canned pumpkin puree and NOT pumpkin pie filling.
- These overnight oats are best stored in the refrigerator for up to 5 days. I do not recommend freezing this recipe. Scroll up the post to view specific meal prep tips.
