2 heads garlic, separated into cloves and peeled
4 cups homemade chicken stock or 4 cups reduced sodium
chicken broth 1 teaspoon chopped fresh thyme or 1/2 teaspoon dried
thyme 4 thin slices French bread
extra-virgin olive oil for drizzling
2 large eggs at room temperature
1/3 cup grated parmigiano-reggiano cheese
salt freshly ground
black pepper Set aside 1 garlic clove to use for rubbing on the toasts. In a saucepan, combine the remaining garlic cloves, the chicken stock, and the thyme. Place over medium heat, bring to a simmer, and cook until the garlic can be easily pierced with a fork, 12 to 15 minutes.
Just before the soup is ready, toast the bread slices, rub them with the reserved garlic clove, and drizzle on a little olive oil. Keep warm.
Remove the soup from the heat and strain through a fine-mesh sieve, discarding the garlic and thyme. In a small bowl, whisk together the eggs and a few tablespoons of the hot soup (off the heat) while stirring constantly. Be sure not to halt your stirring until the eggs are fully incorporated or they can curdle. Add the cheese and stir to integrate, then season to taste with salt and pepper.
Ladle the soup into warmed bowls. Serve the toasts alongside.
