Oatmeal Smoothie High Protein Healthy

Need more healthy smoothie recipes? Try my breakfast smoothie, avocado smoothie, or carrot smoothie next. I used to think there was no breakfast more convenient than overnight oats. That is, until I discovered you can blend oats into smoothies. Turns out, when you blend oats with more traditional smoothie ingredients, you’re left with a thick, creamy smoothie that’s deceptively filling. I can have an oatmeal smoothie and even forget when it’s lunchtime. Now that’s saying something!

Why I love this recipe

Great for weight loss. Oats are full of fiber, peanut butter is naturally satiating, and I even added a scoop of protein powder for good measure. Banana-free. I love banana smoothies, but sometimes, when I make them, I find I’m hungry 10 minutes later. Thickshake texture. It’s like drinking my healthy milkshake. Customize it however you want. I like to add superfoods or swap the nut butter, but you can modify this smoothie however you need to.

Ingredients needed

Rolled oats. Also known as old fashioned oats, these will be blended to add fiber and thickness to the smoothie. Quick oats can also be used, but I wouldn’t recommend steel cut oats as they’re difficult to blend finely. Cocoa powder. Adds essential chocolate flavor plus antioxidants. Protein powder. Optional but highly recommended if you’d like more staying power and extra chocolate flavor. Sweetener. I like using agave or maple syrup, but sugar or sweeteners also work. Chia seeds. Optional, but it thickens the smoothie and gives it an extra boost of fiber and omega-3 fatty acids. Creamy peanut butter or alternative. A spoonful of peanut butter adds tons of richness and helps keep you full for longer. Alternatively, try my low calorie peanut butter or almond butter. Milk. To blend. I prefer unsweetened almond milk, but oat milk or any dairy-free milk works.

Arman’s recipe tips

Taste as you go, and add any sweetener as needed. Thicken the smoothie. Add ice cubes or, if you don’t mind extra calories, add avocado or a dollop of Greek yogurt. Add a dash of cinnamon. To complement the chocolate and peanut butter flavor. Nut-free. Swap the peanut butter for sunflower seed butter or tahini.

Storage instructions

To store: While best enjoyed fresh, this smoothie can be stored in the fridge in a sealed container for up to 3 days. Stir it well before serving.

Strawberry banana oat smoothie. Omit the cocoa powder and peanut butter, and add ½ frozen banana and ½ cup of frozen strawberries. Tropical oat smoothie. Add ½ cup of frozen pineapple and mango. Green oat smoothie. Add 2-3 kale leaves and ½ of a frozen banana for extra sweetness.

To freeze: Pour the smoothie into ice cube trays and freeze for 6 months. When ready to re-blend, place the smoothie cubes into a blender and blend until thick and smooth.
