Ingredients
Method
- Prep the oven and pan: Preheat oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish.
- Season the chicken: Pat chicken dry. Season both sides with salt, pepper, and a pinch of Italian seasoning.
- Optional quick sear: For extra flavor, heat a little olive oil in a skillet over medium-high. Sear chicken 1–2 minutes per side until lightly golden. Transfer to the baking dish.
- Make the garlic sauce: In a small saucepan over medium heat, melt butter. Add minced garlic and cook 30–60 seconds until fragrant. Whisk in cream cheese until smooth, then pour in heavy cream. Stir in Parmesan, Italian seasoning, a small pinch of red pepper flakes, and a little salt and pepper. Simmer 1–2 minutes until slightly thickened.
- Add veggies (optional): If using spinach, stir it into the hot sauce to wilt. If using broccoli, quickly steam it until crisp-tender, then fold into the sauce or scatter around the chicken.
- Assemble: Pour the garlic Parmesan sauce over the chicken. Sprinkle shredded mozzarella evenly on top.
- Bake: Bake 20–25 minutes for breasts (15–20 for thinner cuts, 25–30 for thicker). Chicken is done when it reaches 165°F (74°C) in the thickest part.
- Finish and rest: If you want extra color, broil 1–2 minutes until the cheese is bubbly and lightly browned. Rest 5 minutes. Add a little lemon zest or a squeeze of lemon if you like, and garnish with chopped parsley or chives.
- Serve: Pair with zucchini noodles, a simple salad, roasted asparagus, or cauliflower mash to keep it keto.

How to Store
- Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
- Freeze: Freeze in portioned containers for up to 2 months. Thaw overnight in the fridge for best texture.
- Reheat: Warm gently at 300°F (150°C) until hot, or microwave in 30-second bursts.
Add a splash of cream if the sauce thickens too much.
Health Benefits
- Keto-friendly macros: High in protein and fat with very low carbs, helping support ketosis and steady energy.
- Satiating fats: Cream, cheese, and butter help keep you full, which can reduce snacking and support weight goals.
- Quality protein: Chicken provides essential amino acids for muscle maintenance and recovery.
- Micronutrients: Garlic offers antioxidants; Parmesan adds calcium and phosphorus; optional greens boost fiber and vitamins.
Pitfalls to Watch Out For
- Overcooking chicken: Dry chicken ruins the dish. Use a thermometer and pull it at 165°F (74°C).
- Grainy sauce: Boiling can cause dairy to separate. Keep the heat moderate and stir often.
- Hidden carbs: Avoid pre-shredded cheese with starches or sauces with added sugars.
Read labels.
- Too salty: Parmesan is salty. Season chicken lightly, taste the sauce, and adjust at the end.
Alternatives
- Protein swaps: Use chicken thighs for extra juiciness, turkey cutlets for leaner meat, or shrimp for a quicker bake (reduce time to 10–12 minutes).
- Dairy options: Swap mozzarella for provolone or Gruyère. For a tangy twist, add a spoon of mascarpone or a splash of unsweetened almond milk to loosen the sauce.
- Herb variations: Try fresh thyme, rosemary, or a sprinkle of smoked paprika for depth.
- Veggie add-ins: Mushrooms, spinach, broccoli, or zucchini all work.
Sauté watery veggies first to avoid a thin sauce.
- Spice level: Add more red pepper flakes, a dash of cayenne, or cracked black pepper for heat.

Can I use rotisserie chicken?
Absolutely.
Shred or slice it, arrange in the dish, cover with sauce and cheese, and bake 10–15 minutes until hot and bubbly.
What can I use instead of heavy cream?
Use a mix of cream cheese and unsweetened almond milk, or full-fat canned coconut milk for a dairy-light version. Adjust seasoning to taste.

Use moderate heat, whisk often, and avoid boiling. Add cheese gradually and remove from heat once smooth and slightly thickened.

Cauliflower mash, roasted green beans, sautéed spinach, zoodles, or a simple arugula salad with olive oil and lemon.
