This comforting bowl highlights rolled oats cooked with diced carrots, leek, celery, and potatoes in a savory vegetable broth. Aromatic herbs like thyme and bay leaf infuse the soup, which is enriched with milk or plant-based alternatives and optional greens like spinach or kale. Slightly blended for a creamy texture and garnished with fresh herbs, it offers a hearty, soothing meal ideal for chilly days and nourishing any season.

I discovered this soup on a particularly gray November morning when I couldn't shake the chill from my bones. My grandmother used to make something similar, though she called it her "kitchen sink" soup—a way to use whatever vegetables were wilting in the crisper drawer. The first time I made it myself, I remember standing over the pot, watching the cream swirl into the golden broth, and suddenly understanding why she'd made it so often. It wasn't just food; it was comfort in a bowl, proof that simple ingredients could become something deeply nourishing.

I made this for my friend Maya on a day when she'd had one of those weeks where everything felt overwhelming. She arrived at my door tired, and I had a pot of this waiting. She sat at my kitchen counter, wrapped her hands around the bowl, and we talked for hours while she ate. That's when I realized this soup does something special—it doesn't just fill your stomach, it settles something deeper.

Ingredients

  • Rolled oats (100g): The quiet hero here—they dissolve into the broth just enough to create body and creaminess without any dairy needed. They also add fiber that keeps you satisfied for hours. I learned the hard way that quick oats make the soup gummy, so stick with rolled oats.
  • Carrot, leek, celery, and onion: This is the flavor foundation, the aromatic base that makes people ask what you did to make it taste so good. The secret is taking time to soften them properly—rushing this step steals from the final depth.
  • Potato (1 medium, diced): It adds substance and a subtle sweetness that balances the earthiness of the greens. It also contributes to that naturally creamy texture.
  • Garlic (2 cloves, minced): Mince it fine so it disperses throughout the soup evenly. Garlic in soup should be a flavor you feel rather than a texture you encounter.
  • Spinach or kale (100g, roughly chopped): Add this near the end so it stays bright and tender. The seasonality here matters—use whatever seasonal greens make sense where you are. In spring, try tender lettuce or peas. In fall, kale is perfect.
  • Vegetable broth (1L): This is where quality matters. A flavorful broth makes the difference between soup that tastes like something and soup that tastes like almost nothing. I make my own when I can, but a good store-bought version works beautifully.
  • Milk or plant-based milk (200ml): This softens the soup's edges and adds a gentle richness. Unsweetened works best—let the vegetables sing, not the milk.
  • Bay leaf and thyme: These herbs are the whisper in the background that makes people say 'what is that flavor?' Don't skip them, even though they seem like small things. Fresh thyme is worth the extra effort if you have it.
  • Salt, pepper, and nutmeg: Salt brings everything into focus. A pinch of nutmeg—and I mean a careful pinch—adds a warmth that makes the soup feel luxurious without tasting like anything obvious.
  • Fresh chives or parsley: The final garnish of bright green is more than decoration; it's a flavor surprise that makes each spoonful feel intentional and fresh.

Instructions

Start with the soffritto:
Heat your pot over medium heat and add a splash of olive oil. Let it warm until it's just beginning to shimmer. Now add your onion first, letting it turn translucent—this takes about 2 minutes. Then add the garlic, and immediately follow with the carrot, leek, and celery. Stir them together and listen to that gentle sizzle. Let them cook for about 5 minutes, stirring occasionally, until they're noticeably softer and the kitchen smells like someone who knows what they're doing.
Toast the oats:
Stir in your oats and let them cook for about 2 minutes, stirring frequently. This step is small but important—it develops a subtle nuttiness that deepens the whole soup. You'll notice the oats start to smell toasted and smell less raw.
Build the broth base:
Add your diced potato, bay leaf, thyme, and vegetable broth. Stir everything together, then turn up the heat and let it come to a boil. You'll see the surface begin to move with purpose. Once it's boiling, reduce the heat to a gentle simmer—just the occasional bubble breaking the surface.
The long simmer:
Cover the pot and cook for 15 minutes, stirring occasionally. This is when you can sit down, take a breath, and let the magic happen. The oats soften, the vegetables release their sweetness into the broth, and the whole thing becomes more than the sum of its parts. After about 10 minutes, take a taste—the vegetables should be tender, the oats mostly dissolved but still providing texture.
Final enrichment:
Stir in your milk, the spinach or kale (if using), salt, pepper, and that pinch of nutmeg. Give it a good stir and let it simmer for another 5 minutes. The greens will wilt and turn a deeper color, and the milk will create a subtle, creamy undertone.
Taste and adjust:
Remove the bay leaf (this is important—no one wants to bite into it). Now taste the soup. Does it need more salt? More pepper? A whisper more of thyme? This is your moment to make it exactly right for your palate.
Optional blending:
If you like a smoother soup, use an immersion blender to partially blend it—I usually go for about half blended, leaving some texture. Or leave it as is for more rustic texture. Both ways are right.
Serve with intention:
Ladle it into bowls, let it cool just enough to eat without burning your mouth, then garnish generously with fresh chives or parsley. Watch how the green flakes float on top like edible confetti.

My favorite moment with this soup came when my son, who typically turns his nose up at anything with vegetables he can see, asked for seconds. He didn't realize he was eating kale. We didn't tell him until the bowl was empty and he was already reaching for the bread. That's when I understood that this soup does something beyond nutrition—it brings people together in the most unassuming way.

Seasonality and Vegetable Swaps

One of my favorite things about this soup is how it shifts with the seasons. In spring, I replace the kale with fresh peas or tender lettuce added at the very end. Summer calls for zucchini and fresh basil instead of thyme. Fall is perfect as written, with kale and maybe some roasted squash. Winter is when I add parsnip for extra sweetness and earthiness. The soup becomes a conversation with whatever the farmer's market is offering that week, and each season tastes completely different even though you're making the same dish.

Making It Vegan or Extra Hearty

If you're making this for people who avoid dairy, swap the milk for unsweetened oat milk or almond milk—the soup won't know the difference, and it's just as creamy. For extra protein and heartiness, stir in cooked white beans or lentils in the last few minutes, or add them in the same step as the milk. I've found that white beans almost disappear into the creaminess, while lentils add a slightly earthy punctuation. Whichever you choose, you're making something that feels complete and satisfying.

The Bread Pairing That Makes It Perfect

This soup asks for crusty bread—the kind that's crusty on the outside and soft inside, preferably made with whole grains. I usually tear off a chunk and use it to chase the last bits of soup from the bowl. There's something about the contrast of that bread against the warm, creamy soup that completes the experience. Sometimes I butter the bread. Sometimes I dip it in the remaining soup. Either way, it's the punctuation mark on a good meal. If you have sourdough on hand, that's my first choice, but honestly, any bread made with some substance will do the job beautifully.

  • Toast the bread lightly if it's been sitting out—it adds a welcome crunch
  • Tear the bread rather than cut it, which somehow makes it taste better
  • Don't be shy about letting people have their own bread experience with the soup
