Crockpot Casserole Chicken Green Beans and Potatoes

Sharing is caring!

I am in love with this recipe. This is the perfect summer comfort meal and it will not heat up your kitchen.

Chicken Recipes like this rock my world. I also love that I can us fresh green beans and cook with essential oils.

I know, you may not be a fan of cooking with essential oils yet, but let me tell you…. AMAZING! And if you’re totally against it, we can modify the recipe. I will show you how.

casserole crockpot chicken potatoes and green beans


  • 5-6 chicken breasts
  • 1 purple onion, cut into 8ths
  • 2.5 cups of fresh green beans, ends cut off
  • 4 cups diced potatoes (you can use red potatoes or russet)
  • 2 cloves of garlic, minced (or the jarred stuff)
  • 1/4 cup olive oil
  • 4 drops lemon essential oil (or 1/3 cup lemon juice)
  • 1 drop oregano essential oil (or 1 tsp fresh oregano)
  • salt and pepper to taste

For this I used my awesome new Crockpot Casserole Slow Cooker, which is my new favorite cooking device for summer. You could also use a 6 qt oval slow cooker, but it will be tight. The casserole cooker really gives you lots of room for this recipe. While the casserole dish is only 3.5 qts., you have more base room, you’re just not getting the depth. But that is ok, you don’t need depth for this recipe, you need space on the bottom. Does that make sense?

If you do use the 6 qt., it is going to cook faster, so keep an eye on it.

Arrange the green beans on one end of the crock. Then lay the chicken breasts in the middle. I laid them horizontal from the top. This way they were not overlapping. The on the right hand side add your pile of diced potatoes.

Sprinkle the top with the purple onion sections and salt and pepper.

In a small bowl mix the olive oil, lemon oil, oregano oil and garlic. This is where I buy essential oils online and the brand I use.

Pour this mixture evenly over the green beans, chicken and potatoes.

Pop the lid on it and cook on high for 6 hours in the Casserole Slow Cooker. You can also get the slow cooker in a digital programmable version.

If you’re using the 6 qt., it will likely be done after cooking on high for about 4 hours.¬†You can also get a 6 qt., slow cooker that is digital and programmable.

When it is done… dinner is done. All in one dish.

Add a side of fruit and maybe a salad. You can even add bread.

Trust me here, your family will love this!!
