Equipment

  • 1 Large skillet or sauté pan
  • 1 Medium saucepan (for mashed potatoes)
  • 1 Potato masher
  • 1 Wooden spoon or silicone spatula
  • 1 Chef’s knife
  • 1 Cutting Board
  • 1 Measuring cups and spoons
  • 1 Colander (for draining potatoes)

Ingredients
  

For the Chicken

  • 4 boneless, skinless chicken breasts
  • 1 Salt and pepper to taste
  • 1 tbsp garlic powder
  • 1 tbsp olive oil
  • 1 tbsp butter

For the Sauce

  • 3 cloves garlic, minced
  • 1 cup sliced mushrooms
  • 2 cups fresh spinach
  • 1 cup heavy cream
  • 1/2 cup chicken broth
  • 1/4 cup grated Parmesan cheese
  • Salt and pepper to taste

For the Mashed Potatoes

  • 4 medium potatoes, peeled and diced
  • 2 tbsp butter
  • 1/4 cup milk
  • Salt to taste

Instructions
 

Prepare the Mashed Potatoes

  • Bring a pot of salted water to boil. Add the diced potatoes and cook until fork tender (about 15 minutes).
  • Drain, mash, and mix with butter, milk, and salt. Set aside.

Cook the Chicken

  • Season chicken breasts with salt, pepper, and garlic powder. Heat olive oil and butter in a large skillet over medium heat.
  • Sear the chicken on both sides until golden and cooked through (about 6–7 minutes per side). Remove and set aside

Make the Sauce

  • In the same skillet, add minced garlic and cook for 30 seconds. Add mushrooms and sauté until soft.
  • Pour in chicken broth and cream, stirring constantly. Add spinach and cook until wilted. Stir in Parmesan cheese and season with salt and pepper.

Combine

  • Return the chicken to the skillet and spoon the sauce over the top. Let it simmer for 2–3 minutes.

Serve

  • Plate the mashed potatoes and top with the creamy garlic chicken and sauce. Serve hot.

Notes

  • Chicken substitute: You can use boneless chicken thighs for a juicier alternative. Just adjust cooking time as needed.
  • Dairy-free option: Swap the heavy cream for full-fat coconut milk and use a dairy-free butter substitute for mashed potatoes.
  • Make it ahead: The mashed potatoes and sauce can be prepared in advance and reheated before serving.
  • Add extra flavor: A dash of white wine added before the cream gives a deeper flavor to the sauce.
  • Vegetarian version: Replace chicken with pan-fried tofu or sautéed chickpeas for a satisfying vegetarian meal.
