Ingredients for biaggi's chicken florentine soup
Elegant ingredients for a restaurant-worthy velouté with poached chicken and vibrant spinach.
| Ingredient | Amount | Notes |
|---|---|---|
| Chicken Breast 🍗 | 1 ½ lb | Bone-in, skin-on for flavor |
| Fresh Baby Spinach 🌿 | 4 cups | Packed, stems removed |
| Unsalted Butter 🧈 | 4 tbsp | European-style preferred |
| All-Purpose Flour 🌾 | ¼ cup | Sifted for smooth roux |
| Chicken Stock 💧 | 4 cups | Homemade or high-quality store-bought |
| Heavy Cream 🥛 | ¼ cup | Full-fat for richness |
| Garlic Cloves 🧄 | 3 cloves | Peeled and smashed |
| Shallots 🧅 | 2 whole | Minced for subtle sweetness |
| Dry White Wine 🍷 | ½ cup | Sauvignon Blanc preferred |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Coarsely ground |
| Fresh Thyme Leaves 🌿 | ¼ cup | Stems removed |
| Grated Parmesan Cheese 🧀 | ¼ cup | Freshly grated from block |
The chicken breast quality is non-negotiable here—bone-in, skin-on pieces ensure maximum flavor infusion during poaching. Look for well-marbled cuts from your butcher or a trusted grocer like Whole Foods or Eataly for authentic Italian-style poultry. Fresh spinach should be vibrant green with no wilting, so buy it the day you cook or freeze it first to preserve texture. The butter and flour form the velouté's foundation—European-style butter has higher fat content for a richer roux, and sifted flour prevents lumps that can ruin the silky texture. For the chicken stock, homemade or high-end brands like Pacific Foods make a noticeable difference in depth of flavor.
No white wine? Substitute with extra chicken stock—just add an extra splash of lemon juice to brighten the flavor. Fresh thyme is ideal, but dried thyme at one-third the amount works in a pinch. The shallots add subtle sweetness—substitute with 3 tablespoons minced onion if unavailable. For the Parmesan, grate it yourself from a wedge—pre-grated contains anti-caking agents that make it grainy. The wine can be swapped for dry vermouth if you prefer, but it will alter the flavor profile slightly. If you're short on time, frozen spinach thawed and squeezed dry maintains the green hue, though fresh is superior for texture.
Store any leftover chicken in the broth for up to 3 days—it reheats beautifully and makes excellent sandwiches. The velouté keeps for 4 days refrigerated or 3 months frozen, though the texture may break down slightly upon thawing. For best results, reheat gently over low heat and stir in a splash of cream at the end. The spinach should be wilted just before serving—add it last to preserve its vibrant color. Portion the soup into containers with a layer of cream on top to prevent a skin from forming when refrigerated.

Step-by-step instructions for Biaggi's chicken florentine soup
Master this velouté technique for silky texture and poached chicken perfection.
Poach the Chicken Breast for Tender Results
Bring the 4 cups chicken stock to a gentle simmer in a large pot over medium-low heat. Season with the 1.5 teaspoons salt, 0.5 teaspoon black pepper, and the 0.25 cup fresh thyme leaves. The liquid should shimmer with tiny bubbles but not boil vigorously—this prevents tough meat.
Add the 1.5 lb bone-in, skin-on chicken breast and poach for 12-15 minutes until the internal temperature reaches 165°F and the meat is just cooked through. Use a meat thermometer to check—overcooking will make the chicken dry. Remove the chicken, let it rest for 5 minutes, then carefully shred it into bite-sized pieces with two forks. Reserve the poaching liquid for the soup base.
Build the Velouté Base with Classic Roux Technique
In the same pot, melt the 4 tablespoons unsalted butter over medium heat until foaming. Whisk in the 0.25 cup all-purpose flour to form a smooth paste. Cook for 2-3 minutes until the mixture turns a pale golden color—this is your blond roux, the foundation for velouté.
Gradually whisk in the reserved poaching liquid, about 1 cup at a time, ensuring each addition is fully incorporated before adding more. Stir constantly to prevent lumps from forming. Bring the mixture to a gentle boil, then reduce heat to medium-low and simmer for 10 minutes until thickened enough to coat the back of a spoon.
Infuse with Aromatics and Spinach
In a separate skillet, melt 2 tablespoons of the remaining butter over medium heat. Add the minced 2 whole shallots and smashed 3 cloves garlic, cooking for 3-4 minutes until soft and fragrant—not browned. Pour this aromatic butter into the velouté base and stir to combine.
Add the 4 cups fresh baby spinach all at once and stir vigorously for 1-2 minutes until just wilted. The spinach should brighten the soup's color to a vibrant green. Remove from heat and stir in the 0.5 cup dry white wine and 1 tablespoon lemon juice. This acidity balances the richness while enhancing the spinach's natural sweetness.
Finish with Cream and Poached Chicken
Return the soup to medium-low heat and whisk in the 0.25 cup heavy cream, being careful not to let it boil. Simmer gently for 3-4 minutes until the cream is fully incorporated and the soup reaches your desired consistency. Taste and adjust seasoning with additional salt or pepper if needed.
Gently fold in the shredded chicken and simmer for another 2 minutes to heat through. The chicken should be fully coated in the velouté, absorbing its rich, spinach-infused flavor. Remove from heat and let it rest for 5 minutes to allow the flavors to meld completely.
Serve with Parmesan and Fresh Herbs
Ladle the soup into warmed bowls and garnish each serving with 1 tablespoon of the 0.25 cup grated parmesan cheese and a sprinkle of fresh thyme leaves. The parmesan adds a salty contrast that brightens the dish, while the thyme echoes the herbaceous notes used throughout.
Serve immediately with crusty bread for dipping. The soup should be velvety with visible strands of spinach and tender chicken pieces suspended throughout. Each spoonful should deliver a perfect balance of creamy richness, bright acidity, and delicate spinach flavor—just like Biaggi's signature version.
Pro Tips For Making Biaggi'S Chicken Florentine Soup
- CHOP CHICKEN UNEVENLY: I learned this the hard way—slicing chicken breast too thinly turns it to mush when simmered. Cut pieces into ½-inch thick slabs (not perfect slices) so they hold shape but cook through evenly in the broth.
- MELT BUTTER SLOWLY: High heat burns butter fast, and you’ll end up with a floury paste instead of a smooth roux. Melt the butter over medium-low, stirring constantly, until it’s just golden—about 3-4 minutes. No rushing.
- ADD SPINACH AT THE END: Baby spinach wilts instantly in hot liquid, turning into a sad, watery mess. Wait until the soup is off the heat, then stir in the spinach just until wilted—it’ll stay vibrant and tender, not limp.
- USE COLD CHICKEN STOCK: Room-temperature stock can make your roux break or turn grainy. Chill the stock first, then add it gradually to the butter-flour mixture while whisking—this keeps the sauce silky, not clumpy.
Storing and reheating this recipe
Refrigerator Storage
Store your Chicken Florentine Soup in an airtight container with a layer of heavy cream on top to prevent skin formation. The soup keeps well in the refrigerator for up to 4 days—just make sure it cools completely before storing to maintain its velvety texture.
I like using glass Pyrex containers because they're sturdy and won't absorb flavors. When reheating, stir in a splash of chicken stock if the soup seems too thick after refrigeration. 🥣
Freezer Storage
For longer storage, freeze the soup in airtight, freezer-safe containers for up to 3 months. Leave ½-inch headspace to prevent expansion cracks. When ready to eat, thaw overnight in the refrigerator and reheat gently on the stovetop.
I recommend portioning into individual servings before freezing—this way, you can reheat just what you need without thawing the whole batch. The spinach may soften slightly after freezing, but the flavor remains rich and comforting. ❄️
Reheating Methods
For the best texture, reheat the soup on the stovetop over low-medium heat—never microwave directly, as it can break down the velouté's delicate structure. Stir in 1-2 tablespoons of heavy cream at the end to restore richness.
If the soup seems too thick after reheating, thin it with warm chicken stock or a splash of white wine. The chicken should remain tender, and the spinach should still add vibrant color to each spoonful. 🔥
Reviving Spinach Color
If the spinach loses its bright green hue after reheating, stir in 1 teaspoon of lemon juice or a pinch of salt to refresh its appearance. The acidity helps restore some of the spinach's natural vibrancy.
For extra freshness, add a handful of fresh spinach just before serving—it wilts quickly in the hot soup, bringing back that signature green pop. This trick works especially well if you're reheating leftovers for a quick lunch. 🌿
Chicken Handling Tips
The poached chicken stays moist for 3 days refrigerated or 3 months frozen, but it's best used within 2 days for optimal texture. If the chicken dries out during reheating, simmer it in ½ cup extra chicken stock for 2-3 minutes to restore moisture.
For extra flavor, add a splash of lemon juice or a pinch of fresh thyme when reheating. The chicken should remain tender and fully coated in the velouté. 🍗
Serving Leftovers
Leftovers make a fantastic lunch the next day—just reheat and garnish with freshly grated Parmesan and a sprinkle of black pepper. For a quick upgrade, top with crispy fried shallots or a drizzle of truffle oil if you're feeling fancy.
The soup's creamy texture and rich flavors actually improve after resting overnight, making it perfect for meal prep. Serve with crusty bread or a side of arugula salad to balance the richness. 🥖
Nutrition facts
Frequently asked questions
Why does this recipe use poached chicken instead of shredded rotisserie?
Poaching keeps the chicken juicy and tender while infusing it with the soup's flavors. Rotisserie chicken often dries out when reheated, and its skin can make the velouté greasy. The poaching liquid also becomes part of the soup base, adding depth that store-bought chicken can't match.
Can I make this soup dairy-free?
Yes! Replace the heavy cream with coconut milk or a dairy-free cream substitute, and use olive oil instead of butter for the roux. For extra richness, stir in ½ cup cashew cream at the end. The spinach will still wilt beautifully, though the texture will be slightly lighter.
What's the secret to keeping the spinach vibrant green?
Add the spinach just before serving and wilt it for only 1-2 minutes over medium heat. Overcooking turns it mushy and dull. For extra brightness, stir in 1 teaspoon lemon juice when reheating leftovers. Fresh spinach should be washed and dried thoroughly before adding.
How do I fix a broken velouté texture?
If your soup becomes grainy, whisk in 1 tablespoon cold butter or 1 tablespoon heavy cream while stirring vigorously. For lumps from the roux, strain the soup through a fine-mesh sieve. If it's too thick, thin with warm chicken stock or a splash of white wine. Always cook the roux at medium heat to prevent burning.
Can I prepare this soup ahead of time?
Assemble the soup up to 2 days ahead and refrigerate. Reheat gently on the stovetop, adding a splash of cream or stock to restore texture. For best results, reheat only the portions you'll serve immediately—the spinach may soften further if reheated multiple times. The chicken stays tender when stored properly.
