Instructions for Making Your Keto Jalapeño Popper Casserole
Let’s dive into the steps to create this delicious masterpiece:
Preheat the Oven:
Start by preheating your oven to ensure the casserole cooks evenly and develops that irresistible golden crust.
Cook the Sausage:
In a skillet, brown the ground sausage over medium heat until fully cooked. Drain any excess fat and set aside for later.
Prepare the Filling:
In a large mixing bowl, combine softened cream cheese, cooked sausage, and a splash of hot sauce for extra kick. Mix until smooth and creamy.
Layer the Ingredients:
Spread half of the cream cheese mixture in the bottom of a greased baking dish, then layer sliced jalapeños on top. Add the remaining filling and sprinkle with shredded cheese if using.
Bake to Perfection:
Pop the casserole in the oven and bake until bubbly and golden brown on top. This step ensures everything melds together beautifully.
Finish with Freshness:
Once baked, garnish with chopped green onions for added color and aroma. Let it cool slightly before serving.
Serve Warm:
Slice and serve hot, letting everyone enjoy the cheesy, spicy goodness. Pair with a side salad or keto-friendly breadsticks for a complete meal.
