Classic Vegetable Soup – Simple, Warm & Soul-Soothing.

Today is Tuesday, December 23, 2025.¹ We are in the final 48-hour countdown to the Christmas festivities. For many, this is the most frantic day of the year—filled with last-minute grocery runs, travel delays, and the hum of social obligations. In the midst of this whirlwind, the body often sends a quiet signal for something humble.

The Classic Vegetable Soup is the ultimate culinary “deep breath.” It isn’t trying to be flashy or complex. Its power lies in its transparency: clear broth, tender-crisp vegetables, and the grounding aroma of thyme and bay leaves. It is a “clean-out-the-fridge” masterpiece that hydrates, nourishes, and resets the palate before the heavy feasts of the coming days.

Ingredients

The beauty of this soup is its flexibility. While these are the “classic” inclusions, feel free to swap in whatever is currently in your crisper drawer.

The Aromatic Base

1 tbsp Extra Virgin Olive Oil or Butter.²
1 Medium Yellow Onion: Diced.
2 Large Carrots: Sliced into half-moons.
2 Stalks Celery: Sliced.
3 cloves Garlic: Minced.

The Hearty Body

2 Medium Gold Potatoes: Diced into 1/2-inch cubes.
1 can (14.5 oz) Diced Tomatoes: With their juices.
6 cups Vegetable Broth: Low-sodium is best so you can control the salt.
1 cup Green Beans: Trimmed and cut into 1-inch pieces.
1 cup Corn: Fresh, frozen, or canned.

The Seasoning

1 tsp Dried Thyme or Oregano.
1-2 Bay Leaves: Essential for that “simmered all day” flavor.
1 tsp Sea Salt & 1/2 tsp Black Pepper.
1 tsp Lemon Juice or Apple Cider Vinegar: Added at the very end to “wake up” the flavors.

Instructions: The Building Blocks of Flavor

Even a simple soup benefits from a specific order of operations. We want to layer the flavors so the broth isn’t just “salty water,” but a complex infusion.

1. Sweat the Mirepoix

Heat the oil in a large pot or Dutch oven over medium heat. Add the onion, carrots, and celery.

Sauté for 6–8 minutes. You aren’t looking to brown them; you want them to become soft and translucent. This releases the natural sugars of the vegetables into the oil.

2. Sauté the Garlic

Add the minced garlic and cook for only 60 seconds. Garlic burns easily, and burnt garlic will make your entire pot of soup taste bitter.³

3. The Simmer Begins

Add the diced potatoes, tomatoes (with juice), broth, thyme, bay leaves, salt, and pepper.

Bring the soup to a boil, then immediately reduce the heat to low.
Cover and simmer for 15 minutes.

4. Add the Delicate Veggies

Stir in the green beans and corn. Continue to simmer for another 10 minutes, or until the potatoes and green beans are fork-tender.

Chef’s Tip: If you have a Parmesan rind in your freezer, drop it in during the simmer. It adds a deep, savory “umami” quality to the broth without making it cheesy.

5. The Bright Finish

Turn off the heat. Remove the bay leaves. Stir in the lemon juice or vinegar. Taste and add more salt if needed. This final hit of acid is the difference between a “flat” soup and a “soul-soothing” one.

Flavor & Texture Notes

This soup is defined by clarity. The broth should be light and golden, carrying the earthy notes of the thyme and the sweetness of the carrots.

Texturally, it’s a “spoonful of comfort.” Every bite offers a different sensation: the starchy softness of the potato, the slight snap of the green bean, and the burst of sweetness from the corn. It is a light meal that leaves you feeling clean and energized.

FAQ

Can I make this in a Slow Cooker?

Yes! Add everything except the green beans, corn, and lemon juice. Cook on Low for 6-8 hours or High for 3-4 hours. Add the remaining ingredients in the last 30 minutes.

Why did my vegetables turn mushy?

This usually happens from over-simmering. Once the potatoes are tender, the soup is done. If you plan on reheating the soup later, undercook the vegetables slightly so they reach perfection during the second heat-up.

How long does it stay fresh?

This soup stays wonderful in the fridge for up to 5 days. It also freezes beautifully for up to 3 months—just leave the lemon juice out until you reheat it.
