Detailed Guide: How to Make Spinach Mushroom Chicken

Crafting this flavorful chicken and spinach recipe is straightforward and immensely rewarding. Follow these detailed steps to achieve a perfectly cooked, succulent meal with a rich, savory sauce.

Prepare the Chicken and Aromatics: Begin by preparing your chicken. Take 2 pounds of thin chicken cutlets and slice them into roughly 3-inch long pieces. If using whole chicken breasts, fillet them into thinner cutlets and then gently pound them to about ½-inch thickness using the dull side of a meat tenderizer. This ensures even and quick cooking. Next, thinly slice 1 pound of cremini mushrooms and finely mince or slice 5 cloves of garlic. Having your ingredients prepped beforehand makes the cooking process smooth and efficient.
Season and Dredge the Chicken: Pat the chicken pieces thoroughly dry with paper towels. This crucial step helps achieve a beautiful sear and crispy exterior. Season both sides generously with salt and freshly ground black pepper. Then, lightly dredge the chicken in about ½ cup of flour, ensuring all sides are coated. Shake off any excess flour. A helpful tip for prepping is to place the dredged cutlets on parchment paper; this prevents sticking and makes transfer easier. Discard any remaining flour once the chicken is coated.

Sear the Chicken: Heat a large skillet (a cast iron pan works beautifully here) over medium heat. Add 1-2 tablespoons of olive oil to the hot pan. Carefully place the chicken pieces into the skillet, making sure not to overcrowd the pan. Cooking in batches may be necessary, depending on the size of your pan, to ensure proper browning and even cooking. Sear each side for about 3 minutes, or until the chicken is golden brown and cooked through. Once seared, transfer the chicken to a plate and lightly tent it with aluminum foil to keep it warm while you prepare the sauce. Add a touch more olive oil to the pan between batches if needed.
Cook the Mushrooms: Using the same pan, add the sliced mushrooms. Cook them over medium to medium-high heat, stirring occasionally, until they release their liquid and become beautifully browned and tender, which usually takes about 5-7 minutes. This browning process is essential for developing a rich, umami flavor in your sauce.
Sauté the Garlic: Once the mushrooms are browned, push them to one side of the pan. Add the sliced garlic to the empty side, along with a touch more olive oil if the pan appears dry. Sauté the garlic for about 2 minutes until it becomes fragrant and lightly golden. Be careful not to burn the garlic, as this can turn bitter.
Deglaze and Build the Sauce Base: Season the cooked mushrooms with a pinch of salt and pepper. Pour in 3/4 cup of dry white wine and 1 cup of low-sodium chicken stock. Turn the heat up to high. With a wooden spoon, vigorously scrape up all the delicious browned bits (fond) from the bottom of the pan. These bits are packed with flavor and will contribute immensely to the depth of your sauce. Bring the liquid to a simmer and cook until it reduces by half, which typically takes about 3-5 minutes. Once reduced, lower the heat to medium.

Add Chicken and Spinach: Return the seared chicken pieces to the pan, nestling them among the mushrooms and sauce. Add all 12 ounces of fresh baby spinach on top. It might seem like a lot, but spinach wilts down significantly.
Wilt Spinach and Warm Chicken: Cover the pan with a lid or aluminum foil. Allow it to cook for 2-3 minutes. This steaming action will wilt the spinach and gently warm the chicken through, infusing it with the sauce’s flavors.
Adjust Sauce Consistency (Optional): Taste the sauce and add more salt or pepper if needed. If you find the sauce too thin, you can thicken it using a cornstarch slurry. In a small bowl, combine 2 tablespoons of cornstarch with 2 ounces of water, stirring until smooth. Add half of this mixture to the pan and cook over medium-high heat for about 2 minutes, stirring, until the sauce thickens to your desired consistency. If it’s still too loose, add the remaining mixture. Once satisfied with the thickness, turn off the heat and remove the pan from the burner.

Finish with Butter and Serve: Stir in 3 tablespoons of cubed butter until it completely melts and is incorporated into the sauce. This adds a beautiful sheen and a rich, velvety texture to the sauce. Serve immediately with your favorite crusty bread, pasta, or rice pilaf to savor every last drop of the incredible white wine garlic sauce. Enjoy your homemade spinach mushroom chicken!

Expert Tips for the Best Spinach Mushroom Chicken

Chicken Selection and Preparation: For a speedy meal, opt for pre-packaged thin chicken cutlets. Alternatively, purchase whole boneless, skinless chicken breasts, slice them horizontally to create thinner fillets, and then pound them to an even ½-inch thickness. This ensures uniform cooking and keeps the chicken tender. If you prefer to use boneless, skinless chicken thighs, they are a fantastic alternative, offering a richer flavor profile. Just be aware that thighs typically require a slightly longer cooking time, usually around 5-6 minutes per side, compared to the quicker-cooking breasts.
Mastering the Mushrooms: Cremini mushrooms (also known as Baby Bellas) are our top recommendation for this dish. They are readily available, budget-friendly, and boast a wonderfully earthy flavor that complements the chicken and spinach beautifully. White button mushrooms also work well, or you can experiment with a mix of more exotic varieties for added depth. The key to perfectly cooked mushrooms is patience: allow them to brown thoroughly and release their natural liquids. This process, taking about 5-7 minutes, concentrates their flavor and improves texture. Avoid overcrowding the pan, as this can steam the mushrooms instead of browning them.
The Role of Wine in Your Sauce: Dry white wine, such as a Sauvignon Blanc or Pinot Grigio, adds a complex acidity and depth to the sauce that is truly exceptional. It’s a common ingredient in many of our recipes, like our chicken involtini. If you prefer to cook without alcohol, you can easily substitute the wine with an equal amount of additional low-sodium chicken stock. A small squeeze of fresh lemon juice added at the end can mimic some of the brightness that wine provides.
Achieving the Perfect Sauce Consistency: The sauce is a defining element of this dish; it should be rich and flavorful, with a pleasant thickness that coats the back of a spoon, rather than being watery. If, after reducing, you find your sauce is too thin, a simple cornstarch slurry is your best friend. Whisk together 1-2 tablespoons of cornstarch with 2 ounces of cold water until smooth. Gradually whisk this slurry into the simmering sauce and cook for a few minutes until it reaches your desired thickness. For an even richer, creamier sauce, a splash of heavy cream can be added, though this will increase the calorie count.
Serving Suggestions Beyond Bread: While crusty bread is excellent for soaking up every drop of this delectable sauce, don’t limit yourself! This versatile dish pairs wonderfully with a variety of sides. Consider serving it over creamy mashed potatoes, a delicate pasta like angel hair or orzo, fluffy quinoa, or alongside roasted asparagus or green beans for a complete meal. For an exciting leftover idea, try it on hero bread or garlic bread, topped with melted fontina or mozzarella cheese – it’s a delightful sandwich!
Storing and Reheating Leftovers: Leftover spinach mushroom chicken can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm it in a skillet over medium heat on the stovetop until heated through, adding a splash of chicken stock or water if the sauce has thickened too much. Alternatively, you can reheat portions in the microwave.

Pin Recipe

Simple, one-pan dish featuring tender chicken breasts, fresh baby spinach, and savory cremini mushrooms bathed in a delightful white wine garlic sauce.

Ingredients

2 pounds (908g) thin sliced chicken cutlets (pounded flat)
Salt and pepper to taste
1/2 cup (65g) flour for dredging
1/4 cup (60g) olive oil
1 pound (454g) cremini mushrooms, sliced
5 cloves garlic, sliced
3/4 pound (340g) baby spinach
1 cup (240g) low sodium chicken stock
3/4 cup (180g) dry white wine
3 tablespoons (42g) butter, cubed

For cornstarch slurry (optional)

2 tablespoons (15g) cornstarch
1/4 cup (60g) water

Instructions

Cut chicken into roughly 3-inch long pieces. Pat chicken dry and season well with salt and pepper on both sides. Dredge the chicken in flour on all sides and shake off excess.
Heat a large skillet over medium heat. Add 1-2 tablespoons of olive oil to the pan and once hot, add the chicken pieces. Do not crowd the pan. Sear the chicken for 3 minutes per side (or until cooked through) then place on a plate lightly tented with foil. Work in batches, adding more oil as required, and set all chicken aside.
Add the mushrooms to the same pan and cook until browned (about 5-7 minutes). Once browned, add the garlic to the pan and cook for 2 minutes more.
Season the mushrooms with salt and pepper then add the wine and chicken stock to the pan and turn the heat to high. With a wooden spoon, scrape all of the brown bits off the bottom of the pan. Cook until the liquid reduces by half (about 3-5 minutes) then turn the heat down to medium.
Add in the chicken and the spinach. Cover and cook for 2-3 minutes to wilt the spinach and warm the chicken through.
Taste test the sauce and add more salt or pepper if required. If the sauce is too loose, add half of the optional cornstarch mixture to the pan and cook over medium-high until thickened (about 2 minutes). If still too loose, add the remaining mixture. Once satisfied with the sauce’s consistency, turn the heat off and remove the pan from the heat.
Mix in the cubed butter and stir until melted. Serve with crusty bread to mop up the sauce. Enjoy!

Notes

Boneless, skinless chicken thighs can be substituted for breasts. You will need to cook them longer (about 5-6 minutes per side) than thin-sliced cutlets.
To ensure even cooking, use store-bought thin chicken cutlets or fillet and pound out chicken breasts to about a ½-inch thick.
The cornstarch slurry is an easy way to thicken the sauce if needed. Heavy cream is another option for a richer sauce, though it will increase calories.
Leftovers can be stored in the refrigerator for up to 3 days and reheated in the microwave or on the stovetop over medium heat.
