Add the avocado oil* to the hot pan and swirl to coat the pan.
Place the sausage links in the pan, turning them regularly to brown on all sides. Once browned, remove from the pan and set aside.
Lower the heat and add the butter* to the pan.
Once the butter is melted, add the drained mushroom slices, stirring to allow the moisture to release any cooked sausage bits from the bottom of the pan.
Add the green beans to the pan and let them heat through.
Preheat the oven to 350℉.
Mix the Keto Chow into the chicken broth, stirring until there is no undissolved Keto Chow.
Stir the heavy cream, poultry seasoning, garlic powder, and black pepper into the Keto Chow mixture.
Add the Keto Chow to the green beans and mushrooms in the pan and stir everything together.
Arrange the sausages on top of the green beans.
Transfer the pan to the preheated oven and bake until the casserole is bubbling and the sausages are cooked all the way through. The sausages should register an internal temperature of at least 165℉ on an instant read thermometer.
Notes
*If you are using pork breakfast sausage there will likely be enough fat in the sausage to omit the butter and oil. Prick the skin of the sausage with a toothpick or fork before cooking to allow the fat to cook out.
