Real-Life Story: Why I Fell in Love with Slow Cooker Soups

There was a winter when I was working double shifts and barely had time to cook. My slow cooker became my hero. Tossing in humble ingredients before work and coming home to steaming, aromatic soups made me feel cared for in ways I hadn’t expected.

Lesson: Good food doesn’t need constant attention — just a little faith (and a trusty crockpot).

Common Mistakes to Avoid with Vegan Slow Cooker Soups

• Adding greens too early: It’s best to stir in spinach or kale just before you’re ready to serve the dish. This ensures they retain their vibrant colour and texture.
• Over-seasoning early: Keep in mind that flavors tend to become more intense as the dish cooks. Therefore, it’s advisable to taste the food before making any adjustments to the seasonings.
• Skipping sauté steps for onions/spices: Taking a moment to sauté onions and spices before slow cooking quickly will help unlock and enhance the richness of the flavours in your dish.
• Using too much liquid: Remember that slow cookers do not allow much liquid to evaporate during the cooking process. So, it’s important to be cautious and go easy on the amount of broth you add.

“Slow-cooked soups remind us: good things take time — and they’re worth it.”

Perfect Slow Cooker Plant-Based Soups

• Use dried herbs early, fresh herbs late.
• Add acid (like lemon juice) at the end to brighten flavours.
• Layer textures: hearty beans, tender veg, chewy grains.
• Batch cook and freeze for easy future meals.
