Ingredients

  

• Chicken: 2 large boneless, skinless chicken breasts (or 4 small), or 4 boneless thighs
• Salt and black pepper
• Olive oil
• Butter: 2 tablespoons
• Cremini or button mushrooms: 8 ounces, sliced
• Fresh garlic: 3–4 cloves, minced
• Fresh spinach: 4–5 cups (about 5 ounces)
• Chicken broth: 1 cup (low-sodium preferred)
• Heavy cream or half-and-half: 1/2 cup
• Parmesan cheese: 1/3 cup, finely grated (optional but recommended)
• Italian seasoning or dried thyme: 1 teaspoon
• Red pepper flakes: Pinch (optional)
• Lemon: 1 (for zest and juice)
• All-purpose flour or cornstarch: 1–2 teaspoons (optional, for thickening)
• Fresh parsley: A small handful, chopped (optional garnish)

Instructions

 

• Prep the chicken. Pat the chicken dry and slice large breasts horizontally into cutlets for even cooking. Season both sides with salt, pepper, and a pinch of Italian seasoning.
• Sear the chicken. Heat 1 tablespoon olive oil in a large skillet over medium-high. Add the chicken and cook 3–5 minutes per side until golden and cooked through. Transfer to a plate and tent loosely with foil.
• Sauté the mushrooms. Reduce heat to medium. Add the butter and remaining 1 tablespoon olive oil. Stir in the mushrooms with a pinch of salt. Cook, stirring occasionally, until they release their moisture and turn golden, about 6–8 minutes.
• Add garlic and seasoning. Stir in the minced garlic, red pepper flakes (if using), and another pinch of Italian seasoning. Cook 30–60 seconds until fragrant.
• Deglaze with broth. Pour in the chicken broth. Scrape up browned bits from the bottom of the pan. Simmer 2–3 minutes to reduce slightly.
• Make it creamy. Lower the heat and stir in the cream (or half-and-half). If you want a thicker sauce, whisk 1–2 teaspoons flour or cornstarch into a splash of cold broth first, then stir into the pan. Simmer gently for 2–3 minutes.
• Melt in the spinach. Add the spinach in handfuls, stirring until wilted. Fold in the Parmesan and a little lemon zest. Taste and adjust salt and pepper.
• Return the chicken. Nestle the chicken back into the skillet and spoon the sauce over it. Warm for 1–2 minutes. Finish with a squeeze of lemon juice and chopped parsley.
• Serve. Plate with rice, mashed potatoes, or buttered noodles to soak up the sauce. Add extra Parmesan if you like.

Why This Recipe Works

This dish succeeds because it balances flavor and texture in a smart way. Searing the chicken first locks in moisture and builds a flavorful base for the sauce.

Mushrooms add umami and soak up butter and garlic like a sponge, boosting richness. Fresh spinach softens into the sauce, bringing color and freshness. A touch of cream or half-and-half gives it body without tipping into heavy territory.

Another win: it’s flexible.

You can use chicken breasts or thighs, and the sauce easily adapts to dairy-free or gluten-free needs. The method is simple enough for beginners but still rewarding for more experienced cooks.

How to Make It

1. Prep the chicken. Pat the chicken dry and slice large breasts horizontally into cutlets for even cooking. Season both sides with salt, pepper, and a pinch of Italian seasoning.
2. Sear the chicken. Heat 1 tablespoon olive oil in a large skillet over medium-high.

   Add the chicken and cook 3–5 minutes per side until golden and cooked through. Transfer to a plate and tent loosely with foil.

3. Sauté the mushrooms. Reduce heat to medium. Add the butter and remaining 1 tablespoon olive oil.

   Stir in the mushrooms with a pinch of salt. Cook, stirring occasionally, until they release their moisture and turn golden, about 6–8 minutes.

4. Add garlic and seasoning. Stir in the minced garlic, red pepper flakes (if using), and another pinch of Italian seasoning. Cook 30–60 seconds until fragrant.
5. Deglaze with broth. Pour in the chicken broth.

   Scrape up browned bits from the bottom of the pan. Simmer 2–3 minutes to reduce slightly.

6. Make it creamy. Lower the heat and stir in the cream (or half-and-half). If you want a thicker sauce, whisk 1–2 teaspoons flour or cornstarch into a splash of cold broth first, then stir into the pan.

   Simmer gently for 2–3 minutes.

7. Melt in the spinach. Add the spinach in handfuls, stirring until wilted. Fold in the Parmesan and a little lemon zest. Taste and adjust salt and pepper.
8. Return the chicken. Nestle the chicken back into the skillet and spoon the sauce over it.

   Warm for 1–2 minutes. Finish with a squeeze of lemon juice and chopped parsley.

9. Serve. Plate with rice, mashed potatoes, or buttered noodles to soak up the sauce. Add extra Parmesan if you like.

Storage Instructions

• Refrigerator: Store leftovers in an airtight container for up to 3 days.

  The sauce may thicken; loosen with a splash of broth or water when reheating.

• Freezer: Cream sauces don’t always freeze perfectly, but this one holds up reasonably well. Freeze up to 2 months in a freezer-safe container. Thaw overnight in the fridge, then reheat gently and whisk to smooth.
• Reheating: Warm in a skillet over low heat, adding a bit of broth or cream to prevent drying.

  Avoid boiling to keep the sauce silky.

Benefits of This Recipe

• Nutrient-rich: Spinach adds iron, folate, and vitamin K, while mushrooms contribute B vitamins and antioxidants. Chicken provides lean protein.
• Balanced flavors: Savory mushrooms, bright lemon, and creamy sauce give complexity without a long ingredient list.
• One-pan convenience: Less mess and easy cleanup, perfect for weeknights.
• Flexible and scalable: Works with different cuts of chicken and adapts to dietary needs or what you have on hand.
• Family-friendly: Mild flavors with an option to add heat for those who want it.

Pitfalls to Watch Out For

• Overcooking the chicken: Dry chicken is the quickest way to ruin this dish. Aim for 165°F internal temperature and pull it off the heat as soon as it hits that point.
• Wet mushrooms: Crowding the pan steams the mushrooms.

  Give them space and time to brown for deeper flavor.

• Curdled sauce: Don’t boil the cream. Keep the heat gentle and simmer lightly.
• Under-seasoning: Taste at each stage. Mushrooms and cream need adequate salt and a pop of acid from lemon.
• Too thick or too thin: Adjust with broth to thin or a touch of slurry to thicken.

  Make changes slowly to avoid overcorrecting.

Recipe Variations

• Dairy-free: Use olive oil instead of butter and swap the cream for unsweetened oat or cashew cream. Skip Parmesan or use a dairy-free alternative.
• Gluten-free: Thicken with cornstarch instead of flour and ensure your broth and Parmesan are gluten-free.
• Herb-forward: Add fresh thyme or tarragon at the end for a fragrant finish.
• Smoky twist: Stir in a pinch of smoked paprika with the garlic for depth.
• Wine upgrade: Deglaze the pan with 1/4 cup dry white wine before adding broth.
• Extra veggies: Add sliced onions or shallots with the mushrooms, or toss in sun-dried tomatoes for a sweet-savory note.
• Protein swap: Try turkey cutlets or pork tenderloin medallions using the same method.
• Pasta skillet: Stir in cooked penne or egg noodles and a splash of pasta water to make it a complete one-pan pasta.

FAQ

Can I use frozen spinach?

Yes. Thaw and squeeze it very dry so the sauce doesn’t get watery.

Start with 1 to 1 1/2 cups of thawed spinach, then adjust to taste.

What mushrooms work best?

Cremini (baby bella) have great flavor and hold their shape well. Button mushrooms are fine, too. If you want a stronger mushroom note, mix in some sliced shiitakes.

How do I keep the sauce from breaking?

Use moderate heat, and add the cream after the broth has simmered down slightly.

Avoid vigorous boiling. If the sauce looks too hot, reduce the heat and whisk in a small splash of cream to bring it back together.

Can I make this ahead?

You can cook the chicken and make the sauce up to a day in advance. Store separately, then reheat gently and combine.

Fresh spinach is best added right before serving for color and texture.

What should I serve this with?

It’s great with rice, pasta, mashed potatoes, or crusty bread. For a lighter option, try cauliflower rice or a simple salad on the side.

Is Parmesan necessary?

No, but it adds savory depth and helps the sauce taste more complete. If skipping, add a touch more salt and a small extra squeeze of lemon to balance the flavors.

Final Thoughts

Spinach Mushroom Chicken is a reliable, cozy meal that tastes like more effort than it takes.

With a golden sear on the chicken, deeply browned mushrooms, and a creamy, lemony sauce, it checks all the boxes. Keep it simple or dress it up with herbs and a splash of wine. Either way, it’s an easy win for dinner and even better the next day.

Save this one—you’ll want it in your regular rotation.
