Ingredients You’ll Need

  • Rolled oats – Old-fashioned rolled oats (use gluten-free if needed). They provide texture, fiber, and keep the smoothie satisfying.
  • Banana – One ripe banana (fresh or frozen). Adds natural sweetness and potassium.
  • Greek yogurt – For creaminess, added protein, and a bit of tang.
  • Flaxseed meal – A ground seed that contributes fiber and healthy fats.
  • Milk – Unsweetened almond milk works well, but use oat, soy, dairy, or any milk you prefer.
  • Peanut butter – Adds protein and a nutty flavor. Swap for almond butter or another nut/seed butter if desired.
  • Vanilla extract – A 1/2 teaspoon enhances overall sweetness and aroma.
  • Cinnamon – A pinch or 1/2 teaspoon to round out warm flavors.

If you only have steel cut oats, avoid adding them raw since they’re chewier and take longer to soften. Two easy options:

  • Cook the steel cut oats for 10–15 minutes on the stove or in the microwave, let them cool, then blend into the smoothie.
  • Soak them overnight in water or milk to soften before blending.

How to Make the Banana Oat Smoothie

  1. Add ingredients to a blender: Combine rolled oats, banana, Greek yogurt, flaxseed meal, milk, vanilla, cinnamon, and peanut butter in a blender or food processor.
  2. Blend until smooth: Process until creamy and well combined. Add more milk for a thinner drink or ice/frozen banana for a thicker texture. Taste and adjust sweetness or spice as needed.
  3. Serve: Pour into glasses or jars. Enjoy immediately for the best texture, or chill for a short time before serving.

Tips and Variations

  • Thicker smoothie: Use a frozen banana or add a handful of ice. For extra creaminess without extra sweetness, try frozen cauliflower florets as a neutral-volume booster.
  • Add protein powder: Stir in a scoop of whey or plant-based protein to increase protein content for a post-workout or more filling meal.
  • Natural sweeteners: If you prefer a sweeter smoothie, add a teaspoon of honey or maple syrup, or increase the peanut butter slightly.
  • Vegan option: Substitute plant-based yogurt and non-dairy milk to make the smoothie fully dairy-free and vegan-friendly.
  • Green boost: Add a handful of spinach or kale for extra nutrients—these greens blend smoothly and have a mild flavor when paired with banana.
  • Optional mix-ins: Chia seeds, hemp seeds, or fresh berries work well for added texture, omega-3s, and antioxidants.

Prep and Storage

To store: Keep the smoothie in an airtight jar or container in the refrigerator for up to 2–3 days, though it is best within 24 hours for taste and texture. Separation can occur; shake or stir before drinking. The banana may brown slightly over time.

To freeze: Pour the blended smoothie into freezer-safe containers for up to one month. Thaw in the refrigerator or at room temperature and re-blend if needed. Freezing in small portions or ice cube trays is convenient for individual servings or smoothies for kids.
