How to Make LOW CARB GREEN BEAN CHICKEN CASSEROLE
Step 1: Preheat Your Oven
Preheat your oven to 350 degrees Fahrenheit. This step is crucial as it ensures that your casserole cooks evenly and comes out bubbling hot.
Step 2: Sauté the Mushrooms
In a medium skillet, melt 2 tablespoons of butter over medium heat. Add the sliced mushrooms and cook them for about 2 to 3 minutes until they soften. Sautéing brings out their earthy flavor, which adds depth to your casserole.
Step 3: Mix the Creamy Base
In a large bowl, stir together the cream cheese, sour cream, onion powder, garlic powder, black pepper, and salt until smooth. This creamy mixture not only binds everything together but also creates that luscious texture we all crave.
Step 4: Combine All Ingredients
Toss in the green beans, cooked chicken breast (cut into bite-sized pieces), sautéed mushrooms, and ¼ cup of sliced almonds into the bowl. Mix everything until well combined. This step is where all those wonderful flavors come together!
Step 5: Assemble Your Casserole
Transfer the green bean mixture into a prepared 9×13 baking dish and spread it evenly. Top with the remaining sliced almonds and sprinkle with grated parmesan cheese. This topping will give you that nice golden crust as it bakes.
Step 6: Bake to Perfection
Pop your casserole into the oven and bake for about 30 minutes or until it’s cooked through and bubbly. The aroma wafting through your kitchen will be irresistible! Enjoy this delightful dish hot from the oven with loved ones gathered around.
