It's almost Fall you guys! I am so excited for cooler temperatures and soup for dinner. If you are a soup lover like me, this is the post for you. This Creamy Slow Cooker/Instant Pot Chicken Mushroom Soup is hearty and full of flavor. The perfect meal to come home to after a long day.

It's full of tender chicken pieces and earthy vegetables, all floating in a warm, savory broth. The chicken is moist and flavorful, and the mushrooms add a pleasant chewiness. 

Serve this soup with a hunk of crusty bread and a simple salad and I promise that you will have an easy meal that will satisfy the whole family, even the ones who are prone to say that "Soup isn't a meal". 

Why this soup is perfect for Fall days and RV kitchens

Whether you are lucky enough to spend your days hiking beautiful trails or you are stuck working a 9 to 5 job, it's nice to come home to the wonderful aromas of food cooking in the kitchen. Knowing that dinner is practically ready when you walk in the door is a huge relief on busy days. 

This is one of my favorite go-to meals when the temperatures start to drop. When you walk in the door, you can't help but savor the wonderful aroma of fresh mushrooms and creamy broth that fills the kitchen. 

I love my Ninja Foodi because of recipes exactly like this!

I can cook my chicken quickly using the pressure cooker mode while at the same time creating a rich, flavorful broth. (Seriously, there is no reason to buy the canned stuff).

Ninja Pressure Cooker Chicken and Chicken Stock

Cook it up on the weekend, and then shred or chop the cooked chicken. Use half of it for this recipe and the other half to create an entirely new dinner for another night of the week.

Let's Gather up the ingredients

• Chicken- cooked and diced or shredded

• Butter

• Olive oil

• Fresh onion- diced

• Carrots- diced

• Celery- diced

• Mushrooms- Use your favorites. I like to use a combination of button mushrooms and baby bellas

• Flour

• Chicken broth- homemade is always best

• Tarragon

• Thyme

• Pepper

• Hot pepper sauce- Frank's hot sauce is my favorite brand, but feel free to use your favorite.

• Fresh parsley

• Half-and-half

• Lemon juice

Now Let's Get Cooking

Select the saute function of your Instant Pot / Ninja Foodi / Slow Cooker.

Melt oil and butter in the inner liner

Add vegetables and sauté over medium heat using a wooden or silicon spoon.

Slowly sift flour over vegetables and let cook briefly, stirring regularly. Do not let the flour brown.

Slowly add chicken broth to the vegetable-flour mixture, stirring constantly. Add herbs, pepper sauce, and parsley. Stir well. Cover and use the slow cooker function to cook on low for 6 hours.

Stir in half-and-half, lemon juice and chicken. Bring back to a simmer, using the saute function, and cook for 10 more minutes. Serve immediately.

Serve with a glass of white wine. Top with a bit of parmesan cheese.

If your slow cooker really is JUST a slow cooker follow these instructions:

• Add the butter and onions to a medium skillet and sauté on the stove-top over medium-high heat until the onions turn translucent (about 5 minutes).
• Slowly sift flour over vegetables and let cook briefly, stirring regularly. Do not let the flour brown.
• In a 6 quart or larger slow cooker, add the flour and onion mixture, sliced mushrooms, diced carrots, chicken broth, thyme, and tarragon. Stir to combine.
• Cover and cook on LOW for 6 hours.
• Stir in half-and-half, lemon juice and chicken.
• Recover the slow cooker and continue to cook for an additional 30 minutes.

Optional additions

I think this recipe is perfect as is, but you could always add cooked egg noodles or make it a Mushroom Wild Rice Soup with the addition of some nutty wild rice during the 6 hour cook time.

Add a touch of cream or even a dollop of sour cream to make this soup even richer in flavor.
