Ingredients

  • Oats: You can choose rolled oats for a chewy texture or quick oats if you like them softer. They both provide a sustained energy source due to their complex carbohydrate content.
  • Milk: Whole milk adds calories to this recipe and has a creamy texture. For those seeking non-dairy alternatives, almond, soy, or oat milk are great choices.
  • Protein Powder: Use your preferred protein powder and flavor. I like to use chocolate-flavored whey protein but use any flavor you prefer. If you use casein protein, you may need to add more milk, as casein protein thickens more then whey protein. 
  • Chia Seeds: These tiny seeds are packed with omega-3 fatty acids, fiber, and protein.
  • Greek Yogurt: Aside from its thick texture and rich protein content, Greek yogurt is packed with probiotics. This makes it an excellent choice for gut health, especially in the morning to kickstart digestion.
  •  Peanut Butter: An excellent source of healthy fat and protein, which will help sustain energy levels. If you prefer, you can also use almond butter, or if you have a nut allergy, you can use nut-free seed butter like sunflower butter. 
  • Maple Syrup or Honey: If you have a sweet tooth, add a dash of a natural sweetener like maple syrup or honey.
  • Banana: This adds natural sweetness, vitamins, minerals, and additional calories. If you fancy a change, blueberries are a good alternative.

Expert Tips

Consistency to Your Liking: For thicker overnight oats, reduce the quantity of milk a bit and increase the Greek yogurt. If you lean towards a thinner consistency, prepare the oats as per the recipe. After chilling, if you find it too thick, mix in a little milk until it’s to your liking.

Meal Prep: If you’re preparing the overnight oats in advance, consider mixing the protein powder in just before eating in single servings rather than adding it during initial preparation. This ensures the oats maintain their freshness, lasting up to 5 days in the fridge, compared to the shorter 2-day shelf life when the protein powder is mixed in from the start.

Protein Powder Flavor: Experiment with flavors like chocolate, vanilla, or strawberry. Using non-flavored protein powder? Enhance it with a tablespoon of cocoa powder, turning your overnight oats into a chocolaty delight.

Storage and Leftovers

Store these high calorie overnight oats in an airtight glass container to maintain optimal freshness and flavor. When protein powder is added to your mixture, it’s best to consume the oats within 2 days of refrigeration. But if you omit the protein powder, the oats will remain fresh in the fridge for up to 5 days.

Meal Prep:

If you plan on meal-prepping these overnight oats, it’s better to prepare your mixture without the protein powder. Then, when you’re ready to enjoy a serving, mix in a scoop of protein powder. This way, you can extend the freshness and meal prep for longer.

FAQs

Do I need to include protein powder?

No, you can simply omit the protein powder. If you do skip it, you might want to reduce the liquid quantity slightly to achieve your desired consistency.

What’s the best type of protein powder to use?

It really depends on your goals and preferred texture. Casein offers a creamier texture to your oats and releases protein more slowly, making it great for sustained energy. Whey protein, on the other hand, is absorbed quickly, ideal for post-workout recovery.

Can I use water instead of milk?

Yes! While milk, especially whole milk, imparts a creamier texture and adds more calories (which is the goal of this recipe), you can replace the milk with an equal amount of water if you like.
