– 1 tsp dried rosemary
– Salt and pepper to taste

Keto Onion Chicken Casserole Preparation Method
1. Preheat and Prepare:
Begin by preheating your oven to 375°F (190°C). This temperature will ensure that your casserole cooks evenly, allowing the flavors to meld beautifully while keeping the chicken moist. While the oven is heating, take a moment to lightly grease your 9×13 inch baking dish with a bit of olive oil or cooking spray. This step prevents sticking and makes cleanup easier later.
2. Season the Chicken:
Place your chicken breasts on a clean cutting board. If they’re particularly thick, consider slicing them horizontally to create thinner cutlets – this will help them cook more evenly. In a small bowl, mix together the garlic powder, dried thyme, dried rosemary, salt, and pepper. Sprinkle this seasoning mixture generously over both sides of the chicken breasts, gently patting it in to ensure it adheres well. This step infuses the chicken with flavor from the very beginning.
3. Prepare the Onions:
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add your thinly sliced onions to the skillet. Cook them slowly, stirring occasionally, for about 15-20 minutes until they become golden brown and caramelized. This process brings out the natural sweetness of the onions, adding depth to your dish. If the onions start to stick or brown too quickly, lower the heat slightly and add a splash of water to the pan.
4. Assemble the Casserole:
Once your onions are caramelized, it’s time to assemble the casserole. Start by laying the seasoned chicken breasts in a single layer in your prepared baking dish. Spread the caramelized onions evenly over the top of the chicken. The onions will continue to flavor the chicken as it cooks, creating a delicious harmony of tastes.
5. Create the Cream Sauce:
In a mixing bowl, whisk together the heavy cream and chicken broth. This combination creates a rich, flavorful sauce that will keep your chicken moist during cooking and add a luxurious texture to the finished dish. Pour this mixture over the chicken and onions in the baking dish, ensuring that it’s evenly distributed.
6. Add the Cheese:
Sprinkle your shredded cheese mixture evenly over the top of the casserole. The cheese will melt and brown in the oven, creating a golden, bubbly crust that’s irresistibly delicious. If you’re a true cheese lover, feel free to add a bit extra – there’s no such thing as too much cheese in a keto dish!
7. Bake to Perfection:
Cover the baking dish with aluminum foil. This helps to trap moisture and heat, ensuring that your chicken cooks through without drying out. Place the covered dish in your preheated oven and bake for 25 minutes. After this initial cooking period, remove the foil and continue baking for an additional 15-20 minutes, or until the cheese is melted and bubbly, with golden-brown spots appearing on top. The internal temperature of the chicken should reach 165°F (74°C) when tested with a meat thermometer.
8. Rest and Garnish:
Once out of the oven, let the casserole rest for 5-10 minutes before serving. This resting period allows the juices to redistribute throughout the chicken, ensuring that each bite is moist and flavorful. If desired, sprinkle chopped fresh parsley over the top for a pop of color and fresh flavor.

Notes and Tips
1. Chicken Options: While this recipe calls for chicken breasts, you can easily substitute with boneless, skinless chicken thighs for a slightly higher fat content, which is ideal for keto diets. Just be sure to adjust cooking times accordingly, as thighs may take a bit longer to cook through.
2. Cheese Variations: Feel free to experiment with different cheese combinations. A sharp cheddar provides a nice tang, while mozzarella offers that classic stretchy texture. For an extra flavor boost, try incorporating some grated Parmesan or crumbled blue cheese.
3. Onion Alternatives: If you’re looking to reduce the carb content further, you can substitute some of the onions with sliced bell peppers or mushrooms. These vegetables will still provide a delicious flavor base with fewer carbs.
4. Make-Ahead Option: This casserole can be assembled up to a day in advance and stored in the refrigerator before baking. Just be sure to add about 10-15 minutes to the cooking time if you’re starting with a cold casserole.
5. Leftovers: Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat individual portions in the microwave or the entire casserole in the oven at 350°F (175°C) until heated through.
6. Freezing Instructions: This casserole freezes well. After baking, allow it to cool completely, then cover tightly with foil and freeze for up to 3 months. Thaw in the refrigerator overnight before reheating.
7. Serving Suggestions: While this casserole is a complete meal on its own, you can serve it with a side of steamed low-carb vegetables like broccoli, cauliflower, or zucchini for added nutrition and fiber.
8. Herb Variations: Feel free to play with the herbs used in this recipe. Fresh herbs can be substituted for dried (use about 1 tablespoon fresh for every 1 teaspoon dried). Tarragon, sage, or oregano would all work well in this dish.
9. Dairy-Free Option: For those avoiding dairy, you can substitute the heavy cream with full-fat coconut milk and omit the cheese or use a dairy-free cheese alternative.
10. Spice it Up: If you enjoy a bit of heat, consider adding some red pepper flakes to the seasoning mix or sliced jalapenos to the onion layer.
11. Crispy Topping: For added texture, you could sprinkle some crushed pork rinds or almond flour mixed with a bit of melted butter over the cheese before baking for a crispy, keto-friendly topping.
12. Portion Control: While this dish is keto-friendly, it’s still calorie-dense. Be mindful of portion sizes, especially if you’re watching your calorie intake in addition to carbs.
