    Start strong with a Green Breakfast Smoothie With Oats, a quick, creamy, dairy-free drink made with wholesome spinach, banana, oatmeal, and peanut butter.

    This vegan green shake is ready in minutes and perfect for busy mornings.

    If you love this recipe, you'll also enjoy my green protein smoothie and crisp spinach apple cucumber smoothie.

    Smoothie recipes like this green breakfast smoothie with oats are ones I make regularly because they're simple, nourishing, and surprisingly filling for such a quick recipe.

    On mornings when I forget to prep my overnight oatmeal the night before, this creamy spinach oats smoothie always saves the day.

    The texture is thick yet smooth, with a naturally sweet banana flavor balanced by hearty oats and nutty peanut butter, making it taste like comfort in a glass.

    I'm such a green smoothie lover that I like to mix things up with my pineapple mango spinach smoothie, refreshing parsley smoothie, or energizing spirulina protein smoothie - all tasty, nutrient-packed options to match any mood or morning.

    🍌Ingredients and Substitutions

    Green breakfast smoothie ingredients.
    • Rolled oats: I used rolled oats for a thick, hearty smoothie, but quick oats work too if that's what you have.
    • Spinach: Both baby spinach and regular spinach blend well, so use whichever you prefer.
    • Ground flaxseeds (flaxseed meal): They add creaminess and healthy fats, but you can easily swap them with chia seeds.
    • Peanut butter: I love the flavor, but almond or cashew butter works just as well.
    • Banana: I like using frozen bananas because they makes the smoothie cold, refreshing, and naturally sweet.
    • Date: Adds a caramel-like sweetness, but you can substitute it with maple syrup or agave.
    • Lemon juice: Balances out the spinach and brightens the flavor.
    • Dairy-free milk: I used almond milk, but soy milk, oat milk, or any plant milk you love will work.

    As always, you can find the full recipe with a list of ingredients with measurements in a printable recipe card at the end of this post.

    📋Variations

    • Tropical twist: Add pineapple or mango for a sweet, refreshing flavor.
    • Berry boost: Toss in a handful of frozen berries for a fruity, antioxidant-rich smoothie.
    • Chocolate version: Blend in 1 teaspoon cocoa powder or cacao nibs for a chocolatey green treat.
    • Nut-free: Replace peanut butter with sunflower seed butter or tahini.
    • Extra protein: Add a scoop of vegan protein powder or hemp seeds.

    💡Marinela's Tips

    • Freeze your banana: keeps the smoothie cold and creamy without ice.
    • Adjust thickness: add more plant milk for a thinner drink or extra oats for a shake-like consistency.
    • Sweetness check: Taste before serving and add an extra date or a splash of maple syrup if you like it sweeter.

    ❓Frequently Asked Questions (FAQ's)

    Can I make this smoothie ahead of time?

    Yes! You can prep all the ingredients in a freezer bag and blend in the morning for a quick, grab-and-go green breakfast smoothie.

    Can I use other greens instead of spinach?

    Absolutely! Kale, Swiss chard, or mixed baby greens work well and won't overpower the flavor.
