How to Make Broccoli Fridge Clean-Out Soup
STEP 1. Preheat the oven. Set your oven to 400°F (200°C) to preheat while you prepare the vegetables.
STEP 2. Prepare the vegetables. Spread the broccoli, zucchini, and shiitake mushrooms evenly on a baking tray.
STEP 3. Roast the vegetables. Place the baking tray in the oven and roast for 30 minutes until they are tender and slightly caramelized.
STEP 4. Combine the base. While the vegetables roast, sauté the diced celery, carrots, and red onion in a pot with oil and vegan butter until they become soft and fragrant.
STEP 5. Add roasted vegetables. Once roasted, add the broccoli, zucchini, and shiitake mushrooms to the pot with the sautéed base.
STEP 6. Add broth and seasonings. Pour in 3 to 4 cups of vegetable broth, followed by adding oregano, salt, and pepper to taste.

Pro Tips
- Ensure your vegetables are evenly chopped for uniform cooking.
- Roasting vegetables before adding them to the broth enhances their natural flavors.
- Experiment with different herbs and spices to suit your taste.
- If you enjoy a chunkier soup, reserve some of the roasted vegetables to add back after blending.
- Always taste and adjust the seasoning before serving for optimal flavor.
- Use high-quality vegetable broth for a richer base, or make your homemade version for extra depth.
Common Mistakes to Avoid
- Avoid overcooking the vegetables; they should retain some bite after roasting.
- Don’t skip the roasting phase as it contributes essential flavors and textures.
- If using a high-power blender, blend in small batches to prevent overflow.
- Season gradually; it’s easier to add salt than to adjust if it becomes too salty.
- Make sure to chop vegetables to approximately the same size to ensure even cooking.
- Be mindful of blending hot ingredients; allow them to cool slightly for safety.
