Creamy Avocado Spinach Smoothie for Clean Detox

Silky, verdant and packed with feel-good nutrients, this powerhouse smoothie is the reset button your body has been asking for.

I never planned to fall in love with a green smoothie. I’ve always preferred my breakfasts warm and carb-forward—think banana bread straight from the oven or a skillet of caramelized-onion frittata. But last spring I came back from a long research trip feeling bloated, foggy, and craving something—anything—that felt clean. My blender was the only clean appliance in the kitchen, the spinach in the freezer was still good, and I had a perfectly ripe avocado begging to be used. One minute later, I was staring at the creamiest mint-green blend I’d ever seen. I took a sip and felt like someone had pressed a gentle “refresh” button on my entire system. Ten months later it’s still a twice-weekly ritual, and even my kale-averse husband requests it after his Sunday long runs.

This smoothie is ideal after travel, a holiday season of heavy foods, or simply those Mondays when you want to start the week glowing from the inside out. It is thick enough to feel like a milkshake, naturally sweet, and delivers almost every micronutrient your cells are craving. Let’s break down why it works—then blend away.

Ingredients You'll Need

1 large ripe avocado — The foundation of silkiness. Use a ready-to-eat avocado that gives softly when pressed but has no sunken spots. If all you have is a hard one, pop it in a paper bag with a banana for one night. No avocado? Substitute halffrozen zucchini or Greek yoghurt for a texture shift, but add 1 tsp MCT oil to keep healthy fat levels high.

1 cup lightly packed frozen spinach — Frozen leaves give a frosty texture and keep the smoothie food-safe longer. Frozen spinach contains more vitamin C than fresh spinach that has wilted in the fridge. If you prefer fresh, add 1 cup spinach plus ½ cup ice.

1 cup frozen pineapple — Adds bright sweetness and is loaded with bromelain, an enzyme that supports protein digestion.

1 cup unsweetened almond milk — Choose one without carrageenan for a cleaner flavor. Oat milk works, but the smoothie will be sweeter. For nut-free, use oat, hemp or coconut milk.

½ cup cucumber (peeled if skin is bitter) — Cucumber is 96% water, meaning more hydration without extra volume. I like English cucumber for its mild seeds.

¼ avocado oil or MCT oil — optional — A teaspoon adds more medium-chain trigidlycerides, ideal if you drink this smoothie as a meal replacement.

1 tbsp chia seeds — Thickens the drink and adds omega-3s and soluble fiber to stabilize blood sugar.

1 tbsp fresh lemon juice (about ½ lemon) — Brightens flavor while vitamin C aids iron absorption from spinach.

1 tsp grated fresh ginger — Anti-inflammatory, plus a gentle zing to balance sweetness.

1 tsp maple syrup or ½ pitted Medjool date — Totally optional if your pineapple is very ripe.

How to Make Creamy Avocado Spinach Smoothie for Clean Deto/2 class="mt-5 mb-4" style="color:#10b981;">

Step 1: Chill your blender

Put your blender jar in the freezer for 5 minutes while you gather the rest of your ingredients. A cold jar keeps the smoothie from oxidising, keeping that bright emerald color longer.

Step 2: Layer Liquids First

Add almond milk and lemon juice to the jar. Liquids closest to the blades means you never have to fight air pockets—especially if you’re using a lower wattage motor.

Step 12: Finish with a creamy swirl

Blend on high for 45-60 seconds, stopping to scrape the sides if necessary. Pour into chilled glasses. For the café-style swirl, add 1 tbsp coconut cream and pulse for 2 seconds. Serve immediately; sprinkle chia or hemp hearts on top for crunch.
