1/4 cup heavy cream (optional)

For Garnishing:

Preparation Steps

1. Prepare the Chicken Breasts

Begin by placing the chicken breasts on a clean cutting board.

Pat the chicken dry using paper towels to remove excess moisture. This important step helps the chicken develop a beautiful golden-brown crust when it comes into contact with the hot skillet.

If the chicken breasts are particularly thick, carefully slice them horizontally into thinner cutlets or gently pound them to an even thickness.

Evenly sized chicken pieces cook more consistently and are less likely to become dry on the outside before the center is fully cooked.

Place the prepared chicken into a large mixing bowl.

2. Season the Chicken

In a small bowl, combine the garlic powder, smoked paprika, Italian seasoning, onion powder, salt, and freshly ground black pepper.

Mix the seasonings thoroughly.

Drizzle the chicken with a little olive oil, then sprinkle the seasoning mixture evenly over both sides.

Using clean hands or kitchen tongs, gently rub the spices into the chicken until every piece is well coated.

Allow the chicken to rest in the refrigerator for approximately 15–20 minutes while preparing the vegetables and potatoes.

This gives the seasonings time to develop their flavor and helps create a deliciously seasoned crust during cooking.

3. Prepare the Potatoes

Peel the potatoes and rinse them thoroughly under cold running water.

Cut them into evenly sized chunks, approximately 1–2 inches wide.

Place the potato pieces into a large saucepan and cover them with cold water.

Add a generous pinch of salt.

Starting the potatoes in cold water allows them to heat gradually and cook more evenly.

Place the saucepan over medium-high heat and bring the water to a boil.

Once boiling, reduce the heat slightly and allow the potatoes to simmer for approximately 15–20 minutes.

The potatoes are ready when a fork slides easily through the center without resistance.

Drain them thoroughly in a colander.

Return the drained potatoes to the warm saucepan for approximately 1 minute over very low heat, stirring gently to allow excess moisture to evaporate.

This helps create mashed potatoes with a light, fluffy texture.

4. Make the Creamy Mashed Potatoes

While the potatoes are still hot, add the unsalted butter.

Mash gently using a potato masher until the butter melts into the potatoes.

Slowly pour in the warm milk, adding a little at a time while continuing to mash.

If you prefer especially rich and creamy mashed potatoes, stir in the heavy cream.

Add the garlic powder, salt, and freshly ground black pepper.

Continue mashing until the potatoes become smooth, fluffy, and creamy.

Avoid overmixing, especially with an electric mixer, because excessive mixing can make the potatoes gluey.

Taste and adjust the seasoning as needed.

Cover the saucepan and keep the mashed potatoes warm while preparing the chicken and vegetables.

5. Prepare the Fresh Vegetables

Wash the bell peppers thoroughly and pat them dry.

Remove the stems, seeds, and white membranes.

Slice the red, yellow, and green bell peppers into thick, even strips.

Peel the onion and slice it into medium-thick pieces.

Clean the mushrooms gently using a damp paper towel, then slice them into even pieces.

Peel and finely mince the garlic cloves.

Keeping the vegetables relatively uniform in size helps them cook evenly while maintaining their beautiful colors and textures.

Set the prepared vegetables aside in separate bowls.

6. Heat the Skillet

Place a large, heavy-bottomed skillet over medium-high heat.

Add the olive oil and 1 tablespoon of butter.

Allow the butter to melt and begin to foam gently.

Once the skillet is hot, carefully place the seasoned chicken breasts into the pan.

Arrange them in a single layer without overcrowding.

If necessary, cook the chicken in batches to ensure that each piece develops a golden crust.

7. Sear the Chicken Until Golden Brown

Allow the chicken to cook undisturbed for approximately 5–7 minutes on the first side, depending on its thickness.

As the chicken cooks, the paprika, garlic, and Italian herbs will create a wonderfully fragrant crust.

When the underside becomes golden brown, carefully turn the chicken using kitchen tongs.

Continue cooking for another 5–7 minutes, adjusting the heat if the seasoning begins to darken too quickly.

The chicken should be golden on the outside and juicy on the inside.

Use a meat thermometer to check that the thickest part reaches an internal temperature of 165°F (74°C).

Once fully cooked, transfer the chicken to a clean plate.

Allow it to rest for approximately 5 minutes while preparing the vegetables.

This resting period helps the juices redistribute throughout the meat.

8. Sauté the Mushrooms

Reduce the skillet heat to medium.

Using the same skillet, add a little additional olive oil or butter if necessary.

Add the sliced mushrooms and spread them evenly across the surface.

Allow them to cook undisturbed for approximately 2–3 minutes.

This helps the mushrooms develop a rich, golden-brown color instead of releasing too much moisture.

Stir gently and continue cooking for another 3–4 minutes.

The mushrooms should become tender, lightly caramelized, and full of savory flavor.

Transfer them to a plate and set aside.

9. Cook the Onions Until Soft and Golden

Add 1 tablespoon of butter to the same skillet.

Once melted, add the sliced onions.

Cook over medium heat for approximately 5–7 minutes, stirring occasionally.

As the onions soften, they will begin to develop a beautiful golden color and release their natural sweetness.

If the skillet becomes too dry, add a small splash of chicken broth to prevent sticking.

Continue cooking until the onions are tender and lightly caramelized.

The sweetness of the onions will complement the savory chicken and earthy mushrooms beautifully.

10. Add the Colorful Bell Peppers

Add the sliced red, yellow, and green bell peppers to the skillet with the onions.

Stir gently to combine.

Cook for approximately 5–6 minutes, stirring occasionally.

The peppers should soften slightly while maintaining some of their natural crispness.

Add the dried thyme, oregano, black pepper, and a small pinch of salt.

Continue cooking for another 1–2 minutes.

The vegetables should become glossy and fragrant, with lightly browned edges.

Avoid cooking them for too long, as the peppers should retain their bright colors and tender-crisp texture.

11. Add the Garlic and Mushrooms

Return the sautéed mushrooms to the skillet with the onions and bell peppers.

Add the finely minced garlic.

Stir everything together and cook for approximately 30–60 seconds, just until the garlic becomes fragrant.

Be careful not to burn the garlic, as this can create a bitter flavor.

The skillet should now contain a colorful mixture of tender mushrooms, sweet onions, and beautifully cooked bell peppers.

12. Prepare the Savory Skillet Sauce

Pour the chicken broth into the skillet with the vegetables.

Using a wooden spoon, gently scrape the bottom of the pan to release the flavorful browned bits left behind from cooking the chicken.

These browned bits add wonderful depth and richness to the sauce.

Stir in the Worcestershire sauce and Dijon mustard, if using.

Allow the mixture to simmer gently for approximately 3–4 minutes.

The broth will combine with the natural juices from the vegetables to create a savory, aromatic sauce.

If you prefer a thicker sauce, stir together the cornstarch and cold water in a small bowl.

Slowly pour the mixture into the simmering skillet while stirring continuously.

Cook for another 1–2 minutes until the sauce thickens slightly.

Finish by stirring in the remaining tablespoon of butter and freshly chopped parsley.

The sauce should become glossy, rich, and flavorful without being overly thick.

13. Return the Chicken to the Skillet

Carefully place the cooked chicken breasts back into the skillet.

Nestle them among the sautéed peppers, onions, and mushrooms.

Spoon the warm sauce generously over the chicken.

Allow everything to warm together over low heat for approximately 2–3 minutes.

This helps the flavors blend while keeping the chicken tender and juicy.

Avoid boiling the sauce aggressively, as this can cause the chicken to become dry.

Taste the sauce and adjust the seasoning with additional salt or black pepper if needed.

14. Prepare the Serving Bowls

Choose large, shallow serving bowls or dinner plates.

Spoon a generous portion of creamy mashed potatoes into the bottom of each bowl.

Use the back of a spoon to gently spread the potatoes into a soft, even layer.

Create a small indentation in the center to hold the chicken and vegetables.

The warm mashed potatoes will act as a delicious, buttery base for the savory skillet mixture.

15. Arrange the Chicken and Vegetables

Place the golden chicken pieces over the mashed potatoes.

Arrange the colorful bell peppers, caramelized onions, and sautéed mushrooms around and over the chicken.

Try to distribute the vegetables evenly so that every serving contains a beautiful combination of colors and textures.

Spoon the remaining skillet sauce generously over the chicken and vegetables.

Allow a little of the sauce to flow naturally into the mashed potatoes.

This creates an irresistible combination of creamy potatoes and savory pan juices.

16. Garnish and Serve

Finish the dish with freshly chopped parsley.

Add a light sprinkle of freshly ground black pepper and dried Italian herbs.

For extra richness, drizzle a small spoonful of warm skillet sauce over the top just before serving.

Serve immediately while the chicken is juicy, the vegetables are warm, and the mashed potatoes are soft and creamy.

Every bite should offer a delicious balance of tender chicken, sweet peppers, savory mushrooms, caramelized onions, and buttery potatoes.

Serving Suggestions

Skillet Chicken & Peppers is a complete and satisfying meal on its own, but it can also be paired with a few simple side dishes for an even more enjoyable dinner.

A crisp garden salad with a light lemon vinaigrette provides a refreshing contrast to the richness of the mashed potatoes and savory skillet sauce.

Steamed green beans, roasted asparagus, or lightly sautéed broccoli are also excellent choices.

For a heartier meal, serve with warm dinner rolls or crusty bread to soak up the flavorful sauce.

If you enjoy a slightly spicy flavor, add a small sprinkle of crushed red pepper flakes over the finished dish.

A little freshly grated Parmesan cheese over the mashed potatoes can also add a deliciously savory finishing touch.

Helpful Tips for Perfect Skillet Chicken & Peppers

Use Evenly Sized Chicken Pieces

Chicken pieces of similar thickness cook more evenly and remain tender throughout.

Do Not Overcook the Chicken

Remove the chicken from the heat once it reaches an internal temperature of 165°F (74°C). Overcooking can cause chicken breasts to become dry.

Choose Colorful Bell Peppers

Using red, yellow, and green bell peppers creates a beautiful presentation and provides a balance of sweet and slightly earthy flavors.

Brown the Mushrooms Properly

Allow the mushrooms to cook without constant stirring so they develop a rich, golden color.

Cook the Onions Slowly

Giving the onions enough time to soften and caramelize brings out their natural sweetness.

Use Warm Milk for the Mashed Potatoes

Warm milk blends more smoothly into hot potatoes and helps create a soft, creamy texture.

Avoid Overmixing the Potatoes

Mash gently until smooth. Excessive mixing can release too much starch and make the potatoes sticky.

Use the Same Skillet for Maximum Flavor

Cooking the chicken and vegetables in the same pan allows the ingredients to absorb the delicious browned bits and natural cooking juices.

Finish with Fresh Parsley

Fresh parsley adds brightness and a beautiful finishing touch to the rich, savory dish.

Delicious Recipe Variations

One of the best things about Skillet Chicken & Peppers is how easily it can be adapted to different tastes and preferences.

For a creamier variation, stir a small amount of heavy cream into the skillet sauce just before returning the chicken.

If you enjoy spicy food, add crushed red pepper flakes or a pinch of cayenne pepper to the chicken seasoning.

For a richer mushroom flavor, use a combination of cremini and white button mushrooms.

You can also replace the chicken breasts with boneless chicken thighs for a slightly richer taste and especially juicy texture.

If you prefer a lighter meal, serve the chicken and peppers over cauliflower mash instead of traditional mashed potatoes.

For a different side, try serving the skillet chicken over fluffy white rice, buttered egg noodles, or creamy polenta.

You can also add zucchini, spinach, or cherry tomatoes to the vegetable mixture for extra color and flavor.

Storage and Reheating

Skillet Chicken & Peppers is an excellent recipe for preparing ahead of time because the flavors remain delicious when properly stored and reheated.

Allow the cooked food to cool briefly before transferring it to airtight containers.

For the best texture, store the mashed potatoes separately from the chicken and vegetables whenever possible.

Refrigerate leftovers within 2 hours of cooking and keep them at 40°F (4°C) or below for up to 3–4 days.

To reheat the chicken and vegetables, place them in a skillet over low heat with a small splash of chicken broth.

Cover and warm gently until the chicken reaches an internal temperature of 165°F (74°C).

Reheat the mashed potatoes separately in a saucepan over low heat, adding a small amount of milk or butter to restore their creamy consistency.

Stir gently until the potatoes are heated thoroughly.

Avoid repeatedly reheating the same portion to help maintain the best flavor and texture.
