Simple Avocado Blueberry Smoothie (Vegan, Gluten-Free)

Simple Avocado Blueberry Smoothie (Vegan, Gluten-Free)

When I get back from vacation, the last thing I want to do is meal prep. Coming home to the responsibilities I left behind and loads of laundry to catch up on is tough enough, I don’t want to have to worry about what I’m going to eat the next morning as I begrudgingly get ready for work. This smoothie solves all that. It won’t magically teleport me back to Napa or wherever I returned home from, but it will make the back to work struggle a little bit easier.

How so? Because pretty much everything can be kept in the freezer so it’s ready to go when you get home, without fear of spoiling. That means no after-vacation grocery shopping required. No matter how good my intentions of going to the grocery store are, they never materialize. Same goes for grocery shopping after work. Not going to happen.

Aside from the convenience, this smoothie is creamy enough to feel like a treat (and ween me off of whatever I indulged in on vacation) and packed with vitamins and minerals to help me detox the aforementioned indulgences.

Here’s a breakdown of the good stuff:


The various phytonutrients in blueberries, as well as vitamin C & vitamin A, function as powerful antioxidants. Together, these antioxidants help protect cells against damage from disease-linked free radicals. Studies suggest that antioxidants may also decrease inflammation and prevent oxidative stress.1


These bright green fruits (yep, avocado is a fruit) contain 20 different vitamins and minerals, including more potassium than a banana. They are also loaded with heart-healthy fats. In particular, avocados are high in oleic acid, a monounsaturated fatty acid that is also the major component in olive oil and believed to be responsible for some of its beneficial effects. Eating avocado also helps increase satiety, keeping you fuller for longer – reducing overeating.


There’s a reason Popeye ate so much spinach – it’s loaded with beneficial vitamins and nutrients to help keep your body strong. Spinach has an abundance of potassium, vitamin A, and vitamin K, which help lower blood pressure, maintain bone health, and keep skin and hair healthy. Several of the components in spinach, like potassium, vitamin K, and folate, are associated with slower cognitive decline, reducing the risk of Alzheimer’s for those that consume it regularly.2

Tips for a more wallet-friendly smoothie:

I typically buy an abundance of avocados when they are on sale. When they’re ripe, I cut them into quarters and put them in Ziplock baggies in the freezer – skin removed. It’s the most cost-effective and convenient way I’ve found to always have avocado on hand. I do this with organic berries too. Sometimes I buy them already frozen, but if it’s berry season you can often find fresh ones for cheap. I’ll scoop up some extra and clean them and store in the freezer for smoothies.

So, are you ready for the recipe? If you make it, let me know. I wanna see it! Leave a comment, rate it, and share a photo on Instagram with #dietconfessionals.
