Method
Prepare the biscuit toppers
- In a medium bowl, whisk the self-rising flour, reserving 1 tablespoon for shaping.
- Cut the cold butter into the flour with a pastry blender or your fingertips until pea-size pieces remain.
- Pour in the cold buttermilk and stir just until a shaggy dough forms.
- Turn the dough onto a surface dusted with the reserved flour and pat it into a 3/4-inch-thick rectangle.
- Fold the dough in half and turn it a quarter turn; repeat twice.
- Pat the dough back to 3/4 inch and cut it into 6 equal squares.
- Arrange the biscuits on a plate and refrigerate them while you make the soup.
Make the soup
- In a 6-quart Dutch oven, bring 4 cups of the chicken broth to a gentle simmer over medium heat.
- Add the chicken, cover, reduce the heat to maintain a gentle simmer, and cook 12–18 minutes, until the thickest part reaches 165°F.
- Transfer the chicken to a plate and reserve the broth in the pot.
- When cool enough to handle, shred the chicken.
- Add the olive oil, onion, carrots, and celery to the pot and cook over medium heat for 6–8 minutes, stirring occasionally, until the vegetables begin to soften.
- Stir in the garlic and thyme and cook for 30 seconds.
- Sprinkle in the all-purpose flour and stir for 1 minute.
- Gradually whisk in the reserved broth and the remaining 2 cups broth.
- Stir in the potato, salt, and pepper, bring to a simmer, and cook 12–15 minutes, until the potato is tender.
- Stir in the shredded chicken, peas, and heavy cream and cook over low heat for 3–5 minutes, until the peas are hot.
- Do not let the soup boil, then cover and keep warm over the lowest heat.
Bake and serve
- Heat the oven to 425°F and line a rimmed baking sheet with parchment paper.
- Bake the biscuits for 14–17 minutes, until risen and golden brown.
- Ladle the soup into bowls and serve each topped with a warm biscuit.
Notes
For tender biscuits, stop mixing as soon as a shaggy dough forms, and do not let the soup boil after adding the cream. Refrigerate leftovers for 3–4 days; freezing is not recommended because the cream can separate and the biscuits lose their texture. For a lighter soup, use half-and-half in place of the heavy cream.
