Culinary Tips for the Best Kefir Smoothie
If you want to make smoothies for breakfast and are in a time crunch, place all of the non-frozen ingredients in your blender’s jar and place it in the fridge the night before. Add the frozen ingredients in the morning and blend!
If your smoothie is too thick after blending, add more liquid. If it is too thin, add more fruit or ice. Note that adding more of the optional ingredients will thicken the smoothie.
- Kefir: substitute 1/2 cup plain Greek or regular yogurt + 1/2 cup milk/milk substitute for 1 cup kefir.
- Fresh Fruit: use any fresh fruit. Use creamy fruits such as bananas, avocados, and mangoes to yield creamy smoothies.
- Frozen Fruit: use any frozen fruit. Choose options without any added sugars.
- Leafy Greens: use spinach or kale. If you are unsure about the flavor of greens in your smoothies, start with spinach. Spinach has a milder flavor than heartier greens like kale. Do not use arugula or mustard greens. If you are uncertain about the taste of greens in your smoothie, bananas hide the taste of leafy greens really well!
- Oats: use old-fashioned or quick oats. Do not use steel cut oats, as these need to be cooked.
- Seeds: use chia, hemp, or ground flaxseeds.
- Nut Butter: use almond, peanut, walnut, sunflower, soy nut, or any other variety of your choosing. Choose natural varieties (just nuts and salt) for optimal nutrition.
- Flavor Extracts: use vanilla, almond, coconut, or lemon. Start with 1/4 teaspoon, then adjust to taste.
- Spices: use sweet spices such as allspice, apple spice, cardamom, cinnamon, cloves, ginger, nutmeg, or pumpkin spice.
Base Recipe Variations
Remember that this is a base recipe, so the goal is for you to customize it to your taste!
If the smoothie is too tangy for your taste, add some honey or agave.
“Should I add protein powder to my smoothie?” We don’t recommend it! By adding a few simple ingredients to your morning smoothie, you can satisfy your protein needs and avoid expensive protein powders with questionable ingredients!
For a higher protein berry smoothie, add the optional nut butter, chia seeds, and/or flax seeds.

Which Blender is Best for Smoothies?
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. This recipe features fruit, kefir and leafy greens.
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? 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, a low-fat or fat-free variety is your best choice. If you limit saturated fat in your diet, whole milk varieties are okay.

Leafy green veggies are rich in essential vitamins, minerals, and phytochemicals that promote health and help fight diseases. Blending spinach into a kefir smoothie is an easy way to promote your health.

Will Smoothies Keep in the Fridge?
Keep leftovers in the fridge and enjoy the next day. They can hold for longer than a day but will often begin to separate. Shake before drinking.
