Warm olive oil in a medium pot over medium heat. Add shallot, garlic, lemon zest, and red pepper flakes (if using). Cook, stirring, until fragrant and translucent, 2–3 minutes.
Pour in white wine (if using) and simmer 1 minute to reduce slightly.
Add chicken broth, Parmesan rind, bay leaf, and peppercorns. Bring to a gentle simmer, then cook uncovered over low heat for 20–25 minutes to infuse flavor.
Strain the broth into a clean pot, discarding solids. Return to a gentle simmer.
Stir in spinach until just wilted, 30–60 seconds. Add lemon juice and season with salt to taste.
Ladle into warm bowls. Top with chopped basil and a light drizzle of olive oil. Serve immediately. (If you don’t have a rind, stir in 2 tablespoons (30 ml) finely grated Parmesan off heat instead.)
