Everything You Need To Make This Recipe Without Stress

Gathering your ingredients ahead of time makes the cooking process smooth and enjoyable. Most of these items are pantry staples or easily found at any grocery store.

INGREDIENTS:

• 1.5 pounds boneless, skinless chicken breasts
• 1 tablespoon olive oil
• 1 medium yellow onion, chopped
• 8 ounces cremini mushrooms, sliced
• 3 cloves garlic, minced
• 5 ounces fresh spinach
• 1/2 cup chicken broth
• 1 teaspoon dried Italian seasoning
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/4 cup grated Parmesan cheese (optional, for serving)

For simple substitutions, you can easily swap boneless, skinless chicken thighs for breasts if you prefer a slightly richer flavor and juicier texture; just ensure they are cooked through. If cremini mushrooms aren’t available, white button mushrooms work just as well. Feel free to use fresh thyme or oregano instead of Italian seasoning if you have them on hand – about 1 teaspoon of fresh herbs, finely chopped, would be a great addition. For a dairy-free option, simply omit the Parmesan cheese or use a plant-based alternative.

How To Make It Step By Step With Visual Cues

Follow these straightforward steps to create a delicious and healthy meal in no time.

1. Prepare the Chicken: Pat the chicken breasts dry with paper towels. Cut them into 1-inch bite-sized pieces. Season the chicken all over with 1/4 teaspoon of salt and 1/8 teaspoon of black pepper. This initial seasoning helps build flavor from the start.
2. Sauté the Chicken: Heat the olive oil in a large skillet over medium-high heat. Once the oil is shimmering, add the seasoned chicken pieces in a single layer. Cook for 5-7 minutes, stirring occasionally, until the chicken is browned on all sides and mostly cooked through. It doesn’t need to be fully cooked at this stage, as it will finish cooking with the vegetables. Remove the chicken from the skillet and set it aside.
3. Cook Aromatics and Mushrooms: In the same skillet, add the chopped yellow onion. Cook for 3-4 minutes until it starts to soften and become translucent. Add the sliced mushrooms and cook for another 5-7 minutes, stirring occasionally, until they release their liquid and start to brown. This browning step adds a rich, earthy depth of flavor.
4. Add Garlic and Seasoning: Stir in the minced garlic and dried Italian seasoning. Cook for just 1 minute more, until the garlic is fragrant. Be careful not to burn the garlic, as it can turn bitter quickly.
5. Incorporate Spinach and Broth: Pour in the chicken broth and scrape up any browned bits from the bottom of the skillet with a wooden spoon – this is called deglazing and adds a lot of flavor. Add the fresh spinach in batches if necessary, allowing it to wilt down before adding more. Stir until all the spinach is wilted, which usually takes about 2-3 minutes.
6. Combine and Finish: Return the cooked chicken to the skillet. Stir everything together and cook for another 2-3 minutes, or until the chicken is thoroughly heated through and the sauce has slightly thickened. Taste and adjust seasoning with the remaining salt and pepper if needed.
7. Serve: Remove the skillet from the heat. If desired, sprinkle with grated Parmesan cheese before serving.

Easy Variations And Serving Ideas That Fit Real Life

This versatile chicken and spinach skillet can be easily adapted to suit different tastes and occasions. For a kid-friendly twist, you can serve it alongside some plain pasta or rice, allowing them to mix in the chicken and vegetables as they please. A sprinkle of mild shredded cheddar cheese instead of Parmesan might also appeal to younger palates.

To bulk up the meal, consider serving it over a bed of quinoa, brown rice, or even cauliflower rice for a low-carb option. It also pairs wonderfully with a simple side salad dressed with a light vinaigrette or some crusty whole-grain bread to soak up the delicious juices. For a bit of extra creaminess, stir in a tablespoon or two of cream cheese or a splash of heavy cream at the very end of cooking. You could also add a pinch of red pepper flakes for a subtle kick if you enjoy a little heat. This dish is fantastic for meal prep; simply divide it into individual containers for healthy lunches throughout the week.

Common Slip-Ups And How To Avoid Them

Even simple recipes can have common pitfalls. Being aware of them can help you achieve perfect results every time.

• Overcrowding the Skillet: When cooking the chicken or mushrooms, resist the urge to cram too much into the pan. Overcrowding lowers the temperature, steaming the ingredients instead of browning them. This results in less flavor and a rubbery texture. Cook in batches if necessary to ensure everything gets a nice sear.
• Under-Seasoning the Chicken: Don’t skip seasoning the chicken before it goes into the pan. Salt and pepper at this stage are crucial for building flavor from the ground up. If you only season at the end, the chicken itself might taste bland.
• Burning the Garlic: Garlic cooks very quickly. Add it after the onions and mushrooms have had a chance to soften, and cook it for only about a minute until fragrant. Burnt garlic will impart a bitter taste to your entire dish.
• Overcooking the Spinach: Spinach wilts rapidly. Add it in batches if your skillet is full, stirring until just wilted. Overcooked spinach can become mushy and lose its vibrant color and some nutrients.
• Not Deglazing the Pan: After cooking the mushrooms and onions, there will be delicious browned bits stuck to the bottom of the skillet. When you add the chicken broth, make sure to scrape these up with a wooden spoon. These “fond” bits are packed with flavor and will enrich your sauce.

How To Store It And Make It Ahead Without Ruining Texture

This chicken and spinach skillet is excellent for meal prepping and stores beautifully.

To store leftovers, allow the dish to cool completely to room temperature. Transfer it to an airtight container and refrigerate for up to 3-4 days.

For reheating, you can warm individual portions in the microwave until heated through, usually 1-2 minutes, stirring halfway. If reheating a larger quantity, transfer it to a skillet over medium-low heat on the stovetop. Add a splash of chicken broth or water to prevent drying out and stir occasionally until thoroughly warmed. Be careful not to overcook the chicken during reheating, as it can become tough.

Making this dish ahead is simple. You can chop your chicken, onions, and mushrooms a day in advance and store them separately in the refrigerator. This cuts down on your active cooking time significantly. The cooked dish itself holds up very well, so you can prepare the entire recipe and portion it out for quick meals throughout the week. The spinach might lose a little of its vibrant green color upon reheating, but the flavor and texture will remain delicious.

Questions People Always Ask Before Making This Recipe

Can I use frozen spinach instead of fresh?

Yes, you can use frozen spinach. Make sure to thaw it completely and squeeze out as much excess water as possible before adding it to the skillet to prevent your dish from becoming watery.

What kind of mushrooms are best for this recipe?

Cremini mushrooms (also known as baby bellas) are excellent for their earthy flavor and firm texture. White button mushrooms are a great and readily available alternative. You could also experiment with sliced shiitake or oyster mushrooms for a different flavor profile.
