Ingredients for Chicken Florentine Instant Pot
Chicken, spinach, and Parmesan create this elegant pressure-cooked dish with minimal effort.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Skinless Chicken Breast 🍗 | 1 ½ lb | Pounded to even thickness |
| Fresh Baby Spinach 🥬 | 6 cups | Packed, roughly chopped |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Parmesan Cheese 🧀 | ¾ cup | Freshly grated from block |
| Garlic Cloves 🧄 | 4 cloves | Minced for sauce |
| Unsalted Butter 🧈 | 2 tbsp | For sautéing and sauce |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Chicken Broth 🍲 | ½ cup | Low-sodium preferred |
| Dry White Wine 🍷 | ¼ cup | Optional for deglazing |
| Yellow Onion 🧅 | ½ whole | Finely diced |
| Dried Italian Seasoning 🌿 | 1 tsp | Or fresh herbs if available |
| Kosher Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | To taste |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Olive Oil 🫒 | 1 tbsp | For initial sautéing |
The chicken breast quality matters here. Air-chilled, boneless, skinless from a reputable grocer like Whole Foods or Costco ensures tenderness. Pound to even thickness for uniform cooking. For the Parmesan, Parmigiano-Reggiano is non-negotiable—pre-grated lacks the melt and depth. Buy a wedge and grate it fresh (the microplane does this beautifully).
No white wine? Substitute additional chicken broth with a squeeze of lemon. Fresh spinach only—frozen releases too much water. Heavy cream can be replaced with half-and-half (less rich) or coconut milk (dairy-free). The Italian seasoning is flexible: use one-third the amount of dried if substituting fresh herbs. For gluten-free, swap the flour for cornstarch at half the quantity.
The sauce thickens as it cools. Store leftovers in airtight containers for up to 4 days in the fridge. Reheats well but avoid boiling to prevent curdling. Freezes beautifully for 3 months—thaw overnight before reheating.
Why You’ll Love This Recipe
- Dump and Done: I just toss everything in the Instant Pot—chicken, spinach, cream, garlic—and walk away. No babysitting, no fuss.
- Garlic-Parmesan Dream: The garlic melts into the cream and parmesan, coating the spinach and chicken in this rich, savory sauce. I could drink it with a straw.
- Feeds My Week: I make a double batch on Sunday and it reheats beautifully for lunches. The spinach stays tender, not mushy.
- Pantry to Table: Between the frozen chicken I always have and that bag of spinach about to wilt, this saves me from takeout. Again.
Step-by-Step Instructions for Chicken Florentine
Master this pressure-cooker method for tender chicken and creamy spinach in a fraction of the time.
Step 1: Sauté Aromatics and Brown the Chicken
Set the Instant Pot to Sauté mode and add the 1 tbsp Olive Oil. When shimmering, add the 0.5 whole Yellow Onion and cook for 3-4 minutes until translucent and just beginning to caramelize at the edges.
Add the 4 cloves Garlic Cloves and cook for 30 seconds until fragrant, stirring constantly to prevent burning. Push the aromatics to one side, then add the 1.5 lb Boneless Skinless Chicken Breast in a single layer. Sear for 2-3 minutes per side until golden brown.
This step builds the flavor foundation. The chicken doesn’t need to cook through—just develop a light crust for depth.
Step 2: Deglaze and Pressure Cook
Pour in the 0.25 cup Dry White Wine and scrape the bottom of the pot with a wooden spoon to release any browned bits. Add the 0.5 cup Chicken Broth, 1 tsp Dried Italian Seasoning, 1 tsp Kosher Salt, and 0.5 tsp Freshly Ground Black Pepper.
Secure the lid, set the valve to Sealing, and cook on High Pressure for 8 minutes. The liquid should just cover the chicken—if it doesn’t, add a splash more broth. Once cooking completes, allow a natural release for 5 minutes, then quick-release any remaining pressure.
Step 3: Prepare the Creamy Spinach Sauce
Transfer the chicken to a plate and set the Instant Pot back to Sauté mode. Stir in the 2 tbsp Unsalted Butter until melted, then whisk in the 2 tbsp All-Purpose Flour to form a smooth roux. Cook for 1-2 minutes until lightly golden.
Slowly pour in the 1 cup Heavy Cream, whisking constantly to avoid lumps. Add the 6 cups Fresh Baby Spinach in batches, stirring until wilted before adding more. Simmer for 2-3 minutes until the sauce thickens slightly.
Step 4: Finish with Parmesan and Lemon
Return the chicken to the pot and stir in the 0.75 cup Parmesan Cheese, allowing it to melt into the sauce. The cheese should create a velvety texture without over-thickening. Finally, stir in the 1 tbsp Lemon Juice to brighten the richness.
Let the dish sit for 2-3 minutes off heat to meld the flavors. The spinach should be tender, the sauce should cling to the chicken, and the Parmesan should be fully incorporated. Serve immediately while hot.
Pro Tips For Making Chicken Florentine Instant Pot
- Sear the Chicken First: I learned this the hard way—skipping the sear gives you bland, rubbery chicken. Two minutes per side in the Instant Pot on sauté mode makes a real difference in flavor and texture.
- Wilt Spinach Last: Add the baby spinach only after pressure cooking, then let it sit covered for 3-4 minutes. It’ll wilt perfectly without turning to mush, and you won’t lose that bright green color.
- Thin the Cream: Heavy cream can curdle under high pressure. Stir in 2 tablespoons of warm broth or water to the cream before adding it to the pot—sounds weird, but it works.
- Grate Fresh Parmesan: Pre-shredded parmesan has anti-caking agents that make the sauce grainy. Take the extra minute to grate a block yourself—your sauce will be silkier and more flavorful.
Make-Ahead Tips for This Recipe
Prep Ahead Strategy
I always prep the 1.5 lb chicken breast and 6 cups spinach the night before. Pound the chicken to even thickness, then store in an airtight container. Wash and chop the spinach, keeping it in a separate container with a paper towel to absorb excess moisture.
Sauce Base Prep
Measure out all your dry ingredients—2 tbsp flour, 1 tsp Italian seasoning, and 0.75 cup Parmesan cheese—and store them together in a small container. This saves 5-10 minutes of hunting through cabinets during cooking. 💡
Instant Pot Prep
If your Instant Pot has a removable inner pot, you can prep the entire base (onion, garlic, broth) in it the night before. Store it covered in the fridge, then just set it in the housing and start sautéing in the morning. Cold ingredients may add 2-3 minutes to come to pressure.
Reheating Tips
Store leftovers in airtight containers for up to 4 days. Reheat gently on the stovetop over medium-low heat with a splash of broth or cream to restore the sauce’s velvety texture. Avoid microwaving, as it can cause the sauce to separate.
Freezing for Later
This dish freezes beautifully for up to 3 months. Cool completely, then transfer to freezer-safe containers, leaving 1 inch of headspace. Thaw overnight in the fridge before reheating on the stovetop.
I love having this elegant meal ready to go on busy nights. ❄️

Frequently Asked Questions
Can I use frozen spinach instead of fresh?
Fresh spinach works best for texture, but frozen can work in a pinch. Thaw and drain it completely first to avoid a watery sauce. Squeeze out all excess moisture before adding.
What if my sauce turns out too thin?
Simmer it uncovered on Sauté mode for 2-3 minutes to thicken. If needed, mix 1 tsp cornstarch with cold water and stir in, then cook for 1 more minute.
Can I substitute chicken thighs for breasts?
Yes! Use 1.5 lb boneless thighs and reduce pressure cooking time to 6 minutes. Thighs stay juicier and handle the sauce well.
How do I prevent the sauce from curdling?
Temper the cream by adding a spoonful of hot liquid to it before mixing in. Avoid boiling the sauce and stir frequently while cooking.
