Ingredients

Scale

Vegetables

  • 2 medium leeks, cleaned and sliced
  • 1 medium butternut squash, peeled and cubed
  • 1/2 small savoy cabbage, chopped
  • 1 cup Swiss chard leaves, stems removed and chopped
  • 23 medium heirloom tomatoes (Cherokee Purple preferred), chopped
  • 1 medium bulb onion, chopped
  • 2 stalks celery, chopped
  • 3 cloves garlic, minced
  • 1 bell pepper, chopped

Liquids & Seasonings

  • 6 cups vegetable broth
  • 2 tablespoons olive oil
  • Salt and freshly ground black pepper, to taste
  • 1 tablespoon apple cider vinegar

Bread & Cheese

  • 68 slices rustic crusty bread, suitable for layering in pot and topping
  • 1 cup aged cheese (such as Gruyère or sharp cheddar), grated

Optional Topping

  • 2 eggs, fried sunny-side up

Instructions

  1. Prepare the vegetables: Clean and chop all the vegetables according to the ingredient list. Remove tough stems from Swiss chard and slice leeks thoroughly to remove dirt.
  2. Sauté aromatics: Heat olive oil in a Dutch oven over medium heat. Add chopped onion, leeks, celery, garlic, and bell pepper. Sauté until vegetables become fragrant and softened, about 5-7 minutes.
  3. Add the squash and tomatoes: Stir in cubed butternut squash and chopped tomatoes, cooking for another 5 minutes to meld flavors.
  4. Add broth and cabbage: Pour in the vegetable broth and add chopped savoy cabbage and Swiss chard. Bring the soup to a gentle boil, then reduce heat and simmer, uncovered, for 20-25 minutes until all vegetables are tender and flavors are well combined.
  5. Season and add vinegar: Season the soup with salt and pepper to taste. Stir in the apple cider vinegar to brighten the flavors, then remove the pot from heat.
  6. Prepare the bread layers: Line the bottom of the Dutch oven with a layer of rustic bread slices. Ladle the warm vegetable soup on top of the bread layer evenly.
  7. Add the top bread layer and cheese: Place another layer of rustic bread slices on top of the soup. Sprinkle grated aged cheese generously over the bread layer.
  8. Bake until cheese melts: Place the Dutch oven, uncovered, into a preheated oven at 375°F (190°C) for about 10-12 minutes, or until the cheese is melted and bubbly and the bread is toasted on top.
  9. Optional egg topping: While the soup is baking, fry eggs sunny-side up in a skillet until the whites are set but yolks remain runny.
  10. Serve: Ladle the soup into individual bowls, ensuring some bread and melted cheese are included. Top each serving with a fried egg if desired for extra protein and richness. Serve hot and enjoy the cozy autumn meal.

Notes

  • You can substitute Swiss chard with spinach or kale if unavailable.
  • The soup is flexible — feel free to add or substitute other late-summer or fall vegetables like carrots, parsnips, or turnips.
  • For a vegan version, omit the fried egg and use vegan cheese or omit cheese altogether.
  • Leftover soup can be stored in the refrigerator for up to 3 days and reheated gently on the stovetop.
  • The rustic bread layering adds texture and a deliciously melty cheese topping reminiscent of French onion soup.
