This crockpot spinach soup is my way of holding onto summer, even as the days grow shorter and cooler. I love tossing in fresh, wilted spinach, knowing it will soften into a vibrant, silky broth that’s easy to make on a hectic day. It’s honest food—simple, nourishing, and a little bit nostalgic for those quiet weekend mornings spent in the garden.

Cooking this soup feels like a small act of slowing down. The slow simmer unlocks a subtle sweetness in the spinach, mingling with garlic and a splash of cream for richness. It’s the kind of dish that comforts without fuss, perfect for when you need something warm but don’t want to spend hours in the kitchen.

Every spoonful reminds me that good food doesn’t need to be complicated. This recipe is about embracing the natural flavors of fresh ingredients and letting them do their thing. It’s a humble bowl, but one that feels like a quiet, honest hug after a long day.

This recipe is inspired by my grandmother’s garden, where spinach grew wild and free. I love how this soup captures that nostalgic, earthy scent of fresh spinach, simmered down into a creamy, comforting bowl. It’s a quiet reminder that simple, seasonal ingredients can bring a moment of calm to busy days.

The story behind this recipe

This soup came about on a rainy Sunday, when I opened my fridge and saw a bunch of wilting spinach I’d forgotten about. Instead of tossing it, I threw it into the crockpot with garlic and broth, hoping to save it from the compost pile. The aroma of wilted greens slowly softening into a silky broth was unexpectedly comforting, like a quiet nod to seasons changing.
It’s a reminder that even the most tired produce can be transformed into something nourishing with just a little patience. The slow cooker does most of the work, and I love how this soup feels like a small act of care—simple, honest, and practically effortless when the days get busy.

Ingredient breakdown: key components

Fresh spinach: I love the earthy smell of just-wilted greens, which gives the soup a vibrant, slightly bitter note. If you prefer milder flavor, try baby spinach—it’s tender and less intense.
Garlic: I crush mine to release that pungent, sweet aroma that fills the kitchen. If you’re sensitive to raw garlic, sauté it lightly before tossing it in for a milder, nutty flavor.
Vegetable broth: I opt for homemade when I have time, but store-bought works too. Look for a rich, savory one—skip the overly salty brands if you’re watching sodium.
Cream: I prefer heavy cream for that luscious, velvety texture that coats your palate. For a lighter version, swap with half-and-half or coconut milk—watch how the flavor shifts slightly.
Onion: I use yellow onion for its sweet, mellow base, but shallots can add a subtle, nuanced depth if you want a softer flavor profile. Cook until translucent for best sweetness.
Nutmeg: Just a pinch makes the flavor pop with a warm, aromatic note. If you don’t have it, a dash of cinnamon can add an unexpected warmth that works surprisingly well.
Salt & pepper: I season gradually, tasting as I go. Freshly ground pepper adds a subtle heat, and adjust salt carefully—this soup’s flavor depends on balancing those earthy notes with seasoning.

Notes for ingredient swaps

Dairy-Free: Coconut milk or cashew cream can replace cream for a velvety texture with a hint of sweetness, though the flavor will be slightly different.
Vegetable Broth: Use mushroom broth for a deeper umami hit or water with extra seasoning if you’re out of broth, but expect a lighter flavor.
Fresh Spinach: Frozen spinach works in a pinch; just thaw and drain excess water, though the texture may be slightly softer.
Onion: Shallots add a milder, sweeter note; if you don’t have onion, leeks are a good substitute with a gentle, savory aroma.
Nutmeg: Ground cinnamon can add warmth if you’re out of nutmeg, but use sparingly to avoid overpowering the greens.
Garlic: Garlic powder can work in a pinch; add a teaspoon at the start with the broth, but fresh garlic will give a brighter flavor.
Herbs: Fresh thyme or parsley can brighten the soup; dried herbs should be added earlier for better infusion, but use less to avoid bitterness.

Equipment & Tools

Large slow cooker: To cook the soup slowly and evenly without constant attention.
Stirring spoon: To mix ingredients during cooking and after adding greens.
Ladle: For serving the soup into bowls.
Immersion blender or regular blender: To blend the soup into a smooth, creamy texture.

Step-by-step guide to spinach soup

Gather all your equipment: a large slow cooker, a stirring spoon, a ladle, and a blender or immersion blender for smoothness.
Chop the garlic and onion finely. This helps them release flavor quickly and evenly. Set aside.
Add the chopped onion and garlic to the slow cooker. Pour in the vegetable broth—about 4 cups (950 ml).
Turn the slow cooker on low (around 90°C/194°F) and let it simmer for about 2 hours. The house will smell amazing.
After 1.5 hours, give everything a gentle stir. The onion should be translucent, and the garlic fragrant. If not, give it a little more time.
Add the fresh spinach in batches, stirring gently to wilt. The greens will reduce significantly, about half their volume.
Once the spinach is wilted and tender (about 10 minutes more), use an immersion blender directly in the pot to blend until smooth. Or, carefully transfer to a blender in batches.
Check the soup’s consistency. If it’s too thick, stir in a splash more broth or water. If it’s too thin, let it simmer uncovered for 10 minutes.
Stir in the cream and a pinch of nutmeg. Taste and season with salt and pepper as needed. The soup should be vibrant and silky.
Ladle the soup into bowls. Rest for 5 minutes to let the flavors settle. Finish with a drizzle of cream or a sprinkle of freshly grated cheese if you like.

Let the soup rest for 5 minutes off heat. Finish with a swirl of cream or cheese for extra richness. Serve hot, with crusty bread if desired.

How to Know It’s Done

Color: spinach should be fully wilted and vibrant green.
Aroma: fragrant garlic and onion should fill the kitchen.
Texture: soup should be smooth, velvety, not watery or grainy.
