Cook the Sausage. Over medium heat, cook the ground sausage in a large skillet until browned, breaking it into small crumbles as it cooks.
Once browned, remove the sausage from the skillet and set it aside.
Sauté Vegetables. In the same skillet, melt the butter over medium heat.
Add the diced yellow onion, grated carrot, and celery to the skillet. Sprinkle in the chicken seasoning, salt, and pepper to taste.
Sauté the vegetables for about 5 minutes or until softened.
Remove from heat and set the vegetable mixture aside.
Prepare the Stuffing Mixture. Combine the cooked sausage, sautéed vegetables, keto croutons, chopped pecans, and freshly chopped sage in a large mixing bowl.
Whisk the eggs and chicken broth in a separate small bowl until well combined.
Pour the egg and broth mixture over the stuffing ingredients and toss gently to combine.
Bake the Stuffing. Preheat your oven to 350°F (175°C).
Transfer the stuffing mixture to a greased baking dish.
Bake for 25-30 minutes, until the top is golden and crispy.
Serve. Once baked, remove from the oven and let cool slightly for serving.
