Instructions

  1. Step 1: Heat 1 tbsp olive oil in a medium saucepan over medium heat. Add 1 minced garlic clove and cook for 1 minute until fragrant, stirring constantly.
  2. Step 2: Add 2 cups fresh spinach and cook for 2 minutes until wilted and reduced in volume. Stir in 1 1/2 cups low-sodium chicken broth and simmer for 5 minutes to meld flavors.
  3. Step 3: Remove from heat, let cool slightly, then transfer mixture to a blender. Add 1 peeled and pitted avocado, 1 tbsp lemon juice, 1/4 tsp salt, and 1/8 tsp black pepper. Blend on high for 2 minutes until completely smooth, scraping down sides as needed.

Frequently asked questions

How long does Avocado and Spinach Soup take to make?

Total time is about 20 minutes (10 min prep + 10 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Avocado and Spinach Soup?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep avocado from drying out.

Can I substitute ingredients in Avocado and Spinach Soup?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Avocado and Spinach Soup for a different number of people?

The recipe is written for 2 servings. Multiply each ingredient by (your serving target / 2). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

Is Avocado and Spinach Soup low carb?

Yes — this recipe is tagged low carb based on its ingredient list. Always cross-check labels for packaged ingredients (sauces, broths, condiments) since formulations vary by brand.
