Culinary Tips for the Best Strawberry Kefir Smoothie

If you want to make strawberry kefir smoothies for breakfast and are in a time crunch, place all of the ingredients, except the frozen strawberries, in your blender’s jar and place it in the fridge the night before. Add the strawberries in the morning and blend!

Spinach has a milder flavor than heartier greens like kale, so if you are unsure about the flavor of greens in your smoothies, start with spinach. Leafy greens will turn your beautiful pink smoothie a greenish/brownish hue, but we promise it will still taste great!

Place the oats in the blender before adding the other ingredients and blend into a fine powder if you are unsure about the texture of oats in a smoothie.

Add the oats 1 Tablespoon at a time and taste test between each addition if you are unsure about the flavor of oats in your smoothies. Do this until you reach your desired flavor.

If your smoothie is too thick after blending, add more liquid. If it is too thin, add more fruit or ice.

Ingredient Substitutions

  • Banana: sub another creamy fruit, like mangos or avocados.
  • Strawberries: sub your favorite frozen fruit.
  • Kefir: sub 1/2 cup plain Greek or regular yogurt + 1/2 cup milk/milk substitute for 1 cup kefir.
  • Oats: sub quick oats, but not steel cut. Steel cut oats need to be cooked for optimal digestion.

Recipe Variations

Add a dash of real vanilla or almond extract for extra flavor.

If too tangy for your taste, add some honey or agave.

For more protein, add 1 Tablespoon of nut butter, chia seeds, and or flax seeds.

For a chocolate dipped strawberry kefir smoothie, add 1-2 Tablespoons of cocoa powder. The variations are endless!

Which Blender is Best for Smoothies?

Any blender will work! While a Vitamix probably makes the creamiest smoothies, any full-size blender, single-serve blender, immersion blender, or even food processor will do the job.

Are Smoothies Healthy?

While eating whole fruit is normally best, a smoothie can be a great way to get lots of fruits and/or vegetables in one easy serving. Beyond fruit, this smoothie also features kefir and oats which are both healthy ingredients! The combination of probiotic bacteria and prebiotic fiber make this a super gut-friendly smoothie! Learn all about prebiotics and probiotics in this article!

Fresh & Frozen Fruit

Both fresh and frozen fruit is healthy. Fruit contains fiber, water, vitamins, minerals, and phytochemicals. All of these nutrients help your body fight, prevent, and manage diseases. Aim to include a variety of colors throughout the week.


What is kefir? What kind should you buy? Kefir is a fermented milk beverage – basically a pourable yogurt drink. It is high in probiotic cultures, which makes for a happy gut. We recommend buying plain varieties to avoid added sugars and organic, if you can afford it. Select a fat content that works with your overall diet. If you tend to consume a lot of foods high in saturated fat (i.e. lots of animal products), a low-fat or fat-free variety is the best choice. If you limit saturated fat in your overall diet, whole milk varieties are okay.

Oats in a Smoothie?

Yes! Oats add fiber and complex carbohydrates. Fiber is important for digestion, satiety, stable blood sugar, good cholesterol, and healthy gut bacteria. The soluble fiber in oats acts as a prebiotic to feed the healthy bacteria in your gut. Complex carbohydrates are important for steady energy and focus. (1, 2)
