Ingredients Method

Ingredients

  

• 1.5 pounds boneless, skinless chicken breasts or thighs, patted dry and cut into bite-size pieces
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1 teaspoon smoked paprika (or sweet paprika)
• 1/2 teaspoon dried Italian seasoning or dried oregano
• 2 tablespoons olive oil
• 2 tablespoons butter
• 1 small yellow onion, finely chopped
• 3–4 cloves garlic, minced
• 1/2 cup low-sodium chicken broth
• 1/2 cup heavy cream (or 1/3 cup coconut milk for dairy-free)
• 1 teaspoon Dijon mustard
• 1 tablespoon fresh lemon juice, plus extra wedges for serving
• 4–5 cups fresh baby spinach (about 5 ounces)
• 1/4 cup grated Parmesan cheese (optional but recommended)
• Red pepper flakes, to taste (optional)
• Fresh parsley, chopped, for garnish (optional)

Method

 

1. Season the chicken: In a bowl, toss the chicken with salt, pepper, smoked paprika, and Italian seasoning. Coat evenly.
2. Sear the chicken: Heat olive oil in a large skillet over medium-high. Add the chicken in a single layer and cook 4–6 minutes, turning once, until golden and just cooked through. Transfer to a plate.
3. Soften the aromatics: Reduce heat to medium. Add butter to the same skillet. Stir in the onion and cook 3–4 minutes until translucent. Add garlic and cook 30 seconds, until fragrant.
4. Deglaze the pan: Pour in the chicken broth. Scrape up any browned bits with a wooden spoon. Let it simmer for 1–2 minutes to reduce slightly.
5. Build the sauce: Stir in the heavy cream and Dijon. Simmer on low for 2–3 minutes, stirring often, until the sauce thickens slightly. Add lemon juice and a pinch of red pepper flakes if using.
6. Add spinach: Pile the spinach into the skillet. It will look like a lot, but it wilts quickly. Stir until it softens and blends into the sauce, 1–2 minutes.
7. Finish the chicken: Return the chicken and any juices to the skillet. Stir to coat in the sauce and warm through for 1–2 minutes.
8. Cheese and season: Stir in Parmesan. Taste and adjust with more salt, pepper, or lemon as needed. The sauce should be savory and bright.
9. Serve: Sprinkle with parsley and serve hot with rice, quinoa, mashed potatoes, or crusty bread.

1. Season the chicken: In a bowl, toss the chicken with salt, pepper, smoked paprika, and Italian seasoning.

Keeping It Fresh

• Storage: Let leftovers cool, then store in an airtight container in the fridge for up to 3 days.
• Reheating: Warm gently in a skillet over low heat with a splash of broth or water to loosen the sauce.

  Avoid boiling so the chicken stays tender.

• Freezing: The creamy sauce can separate after freezing, but it’s still edible. If you plan to freeze, skip the Parmesan and add it after reheating. Freeze up to 2 months.
• Make-ahead tips: Chop onions and garlic ahead of time.

  Pre-cut and season the chicken up to 24 hours in advance and keep it refrigerated.

Health Benefits

• Lean protein: Chicken provides protein to keep you full and support muscle health.
• Leafy greens: Spinach adds iron, vitamin K, folate, and antioxidants with very few calories.
• Balanced fats: Olive oil and a moderate amount of dairy make the dish satisfying without going overboard.
• Lower sodium potential: Using low-sodium broth and seasoning with lemon lets you control salt more easily.
• Gluten-free friendly: The recipe is naturally gluten-free if your broth and mustard are certified gluten-free.

What Not to Do

• Don’t overcrowd the pan: If your skillet is small, cook the chicken in two batches. Overcrowding steams the meat and prevents browning.
• Don’t boil the cream: High heat can cause the sauce to break. Keep it at a gentle simmer.
• Don’t skip the deglazing: Those browned bits carry flavor.

  The broth pulls them into the sauce.

• Don’t add spinach too early: Add it near the end so it stays vibrant and tender.
• Don’t forget to taste: A squeeze of lemon and a pinch of salt at the end can transform the dish.

Variations You Can Try

• Dairy-free: Use coconut milk instead of cream and skip the Parmesan. Add extra lemon to brighten.
• Mushroom lover’s version: Sauté 8 ounces of sliced mushrooms with the onions for extra savoriness.
• Tomato twist: Add 1/2 cup halved cherry tomatoes with the spinach. Their sweetness balances the sauce.
• Herb-forward: Swap Italian seasoning for fresh thyme and basil.

  Stir in basil just before serving.

• Spicy: Add 1 teaspoon Calabrian chili paste or more red pepper flakes to the sauce.
• Creamy feta: Skip Parmesan and crumble in 1/3 cup feta at the end for tangy richness.
• Greens swap: Use chopped kale or Swiss chard. Sauté a few minutes longer before adding cream so they soften.
• Protein swap: Use turkey cutlets or shrimp. For shrimp, cook them quickly first, then add back at the end.

FAQ

Can I use frozen spinach?

Yes.

Thaw it first and squeeze out as much water as possible. Add it after the sauce thickens so it doesn’t dilute the flavors.

What’s the best cut of chicken for this?

Chicken thighs are forgiving and stay juicy. Chicken breasts work well too—just avoid overcooking them during the sear.

How do I make it lighter?

Use half-and-half or evaporated milk instead of heavy cream, and reduce the butter to 1 tablespoon.

The sauce will be a bit thinner but still tasty.

Can I make it without mustard?

Yes. Dijon adds gentle tang and helps the sauce emulsify, but you can leave it out or replace it with a small splash of white wine.

What should I serve with it?

Rice, mashed potatoes, cauliflower rice, or pasta are great. Crusty bread is perfect for soaking up the sauce.

How do I avoid dry chicken?

Cut pieces evenly, sear over medium-high heat, and remove them once they’re just cooked through.

Finishing them in the sauce keeps them tender.

Can I add more vegetables?

Absolutely. Bell peppers, zucchini, or peas work well. Sauté firmer veggies with the onions so they soften in time.

Is it kid-friendly?

Usually, yes.

Keep the red pepper flakes mild, and you can chop the spinach more finely if texture is a concern.
