  • Mushrooms – I used baby bella in this recipe

  • Unsalted butter
  • Olive oil
  • Seasonings: salt, pepper, garlic powder, onion powder, dried Italian seasoning, freshly chopped parsley
  • Minced garlic
  • Half and half – or substitute with heavy cream
  • Freshly grated parmesan cheese
  • Fresh baby spinach
  • Flour – or thickener of choice, such as arrowroot or cornstarch

HOW TO COOK CHICKEN:

Whether you’re using chicken breasts or thighs, it is important to make sure the internal temperate of the chicken reaches 165 degrees F read from the thickest part of the breast/thigh. I use a Digital Meat Thermometer that is very easy to use and gives me a fast reading.

  • If using two large chicken breasts, slice each in half lengthwise. Rinse and pat each one dry with a paper towel. Season with salt, pepper, garlic powder and onion powder.
  • Depending on how thickly cut the chicken breasts are (or if you’re using chicken thighs), cooking times may vary. Sear for 3-5 minutes per side or until the internal temperature reaches 165 degrees F using a meat thermometer.
  • Whether thighs or breasts, be sure to not over-crowd the skillet. This will affect the chicken searing fully and evenly.
  • The chicken should reach a golden brown color (as you see pictured) before flipping.

INGREDIENT SWAPS AND CONSIDERATIONS:

  • Flour — this is used as a thickener in this recipe. You can swap this out for cornstarch or arrowroot.
  • Half and half — an important ingredient that helps to make the sauce creamy! This can be swapped out for heavy cream or milk of choice. Please note: I have only made this with half and half and heavy cream, so I cannot attest to the taste or consistency of milk and dairy-free milk alternatives.
  • Dried herbs — I generally use dried herbs in my recipes, as that is what I always have on hand in my pantry. Fresh is definitely doable!
    NOTE: Being that dried herbs are more concentrated than fresh, you will need 3x more fresh herbs than dried.

    • EXAMPLE: 1 teaspoon of dried herb = 1 tablespoon of fresh
  • Mushrooms & spinach —If you’re not a fan of one or the other, simply double up on the amount of spinach to make a creamy spinach chicken dish or omit the spinach entirely.
  • Unsalted items — In all of my recipes, I tend to use ‘unsalted’ or ‘low-sodium’ cooking items. Whether it be unsalted stocks or broths, canned tomatoes, or butter – they are always unsalted or low-sodium. The reason behind this is because I prefer to be able to add the salt myself and to my taste preference.
  • Chicken stock — stock will provide more flavor to the dish, but you can also use broth. Don’t have chicken broth or stock on hand? Use vegetable!

Ingredients:

Chicken:

  • 4 boneless, skinless chicken breasts, (thinly sliced)
  • 1/2 tsp garlic powder
  • 1/4 tsp onion powder
  • salt and pepper, (to taste)
  • 2 tbsp olive oil

Creamy Mushroom and Spinach Sauce

  • 10 ounces baby bella mushrooms, (sliced)
  • 2 1/2 tablespoons unsalted butter
  • 2 garlic cloves, (minced)
  • 1 tablespoon flour, (can subtitute *SEE NOTES BELOW)
  • 1/2 cup unsalted chicken stock
  • 1 cup half and half, (or heavy cream/milk of choice)
  • 1/2 teaspoon dried Italian seasoning
  • 1/2 teaspoon salt, (more or less - to taste)
  • 1/4 teaspoon pepper, (more or less - to taste)
  • 1/2 cup freshly grated parmesan cheese
  • 1 cup fresh baby spinach, (roughly chopped)

Garnishment:

  • freshly chopped parsley

Instructions:

  • Season chicken with salt, pepper, garlic powder, and onion powder.
  • Heat the olive oil in a large skillet over medium-high heat.
  • Once the pan and the oil are hot, add the chicken. Allow both sides to sear for 3-5 minutes. Time will depend on how thickly cut the chicken is. The internal temperature should read 165 degrees F in the thickest part of the chicken using a meat thermometer.
  • Remove the chicken to a plate; set aside and cover to keep warm.
  • If the pan appears dry, add 1 additional tablespoon of olive oil and allow to heat.
    To the skillet, add the sliced mushrooms. Allow to saute for 3-4 minutes. Water will naturally release. Saute until no water remains.
  • Using a slotted spoon, remove the mushrooms to the same plate as the chicken and cover to keep warm.
  • To make the sauce, add the butter to the skillet to melt. Once the butter is just starting to bubble, add the minced garlic. Saute for 30 seconds and then whisk in the flour to thicken.
  • Whisk in the chicken stock, half and half, and the Italian seasoning. If using unsalted stock/broth, season with salt and pepper, to taste.
    Using a wooden spoon or spatula, stir well, making sure to scrape any bits off of the skillet as the stock heats.
  • Allow to simmer for 2-3 minutes before adding the parmesan cheese, stirring until melted and the sauce has begun to thicken slightly. Add the chopped spinach and cook until it starts to wilt.
  • Add the chicken and mushrooms back to the sauce to warm for 1-2 minutes. Remove from heat.
  • Garnish with freshly chopped parsley and serve over mashed potatoes, quinoa, rice, or your favorite pasta!

Notes:

Half and half: This is equal parts whole milk and heavy cream. You can substitute this with heavy cream or milk of choice. I have only cooked this dish with half and half and heavy cream, so I cannot attest to using other milks or milk alternatives.
Flour: This is used as a thickener for the sauce. You can use regular flour or gluten-free. If using cornstarch, use half as much cornstarch (1/2 tablespoon with 1-2 tablespoons of water). This rule also applies to other starches used as thickeners: potato starch, arrowroot starch, and tapioca.
- If using a starch as a thickener, skip the step of adding to the pan after the garlic has sautéed. Add it once you have added the stock, half and half and seasonings. Scrape the bottom of the pan to thoroughly mix and then add the starch mixture to thicken, stirring frequently to fully mix.
