Ingredients
The Base:
- 1.5 lbs Chicken breast (or boneless skinless thighs), cut into bite-sized cubes
- 2 cups Broccoli florets (fresh is best for texture)
- 1 cup Cherry tomatoes, whole
- 2 cups Fresh spinach (roughly chopped or whole baby spinach)
- 2 tbsp Avocado oil (or olive oil)
The Seasoning:
- 1 tsp Garlic powder
- 1 tsp Onion powder
- 1 tbsp Italian seasoning
- 1/2 tsp Salt (plus more to taste)
- 1/2 tsp Black pepper
The Creamy Tuscan Sauce:
- 1/3 cup Sun-dried tomatoes (julienne cut, packed in oil is fine)
- 1 tbsp Fresh garlic, minced
- 1 cup Half and half (use heavy cream for lower carb/keto)
- 1/2 cup Fresh Parmesan cheese, grated
- 4 oz Fresh Mozzarella cheese, torn into chunks or pearls
- Optional: 1/4 cup Creamy garlic sauce (like Chosen Foods Chicken Sauce) for serving
Instructions
- Preheat and Prep: Preheat your oven to 400°F (200°C). Get a large casserole dish or a 9×13 baking pan ready.
- Combine Base Ingredients: Directly in your baking dish, add the cubed chicken breast, broccoli florets, cherry tomatoes, and a generous handful of fresh spinach.
- Oil and Season: Drizzle the avocado oil over the chicken and vegetables. This ensures the seasonings stick and helps roast the veggies. Sprinkle the garlic powder, onion powder, Italian seasoning, salt, and black pepper evenly over the mixture. Toss everything together in the pan until well coated.
- Add Tuscan Aromatics: Scatter the sun-dried tomatoes and minced fresh garlic over the seasoned chicken and veggie mixture.
- Make it Creamy: Pour the half and half (or heavy cream) all over the dish. This liquid will mix with the juices from the chicken and tomatoes to create a rich sauce as it bakes.
- Add Cheese: Top the casserole with the fresh grated Parmesan cheese. Then, distribute the pieces of fresh mozzarella evenly on top to ensure you get those beautiful golden brown cheesy spots.
- Bake: Place the dish in the oven and bake for 20 minutes, or until the chicken is cooked through (internal temp of 165°F) and the cheese is bubbly and slightly browned.
- Serve: Remove from the oven and let it rest for a few minutes. If desired, drizzle with a savory creamy sauce or fresh herbs before serving. Enjoy your high-protein, low-carb masterpiece!

Common FAQs about Low Carb Tuscan Chicken Bake
Why is avocado oil preferred over olive oil for this recipe?
Avocado oil has a high smoke point (up to 500°F), making it safer and more stable for a 400°F oven. It won’t oxidize or develop a burnt flavor like some extra virgin olive oils might at high heat.
What role does the acidity of the cherry tomatoes play?
The natural acidity in the tomatoes acts as a “brightener.” It cuts through the richness of the heavy cream and cheese, balancing the dish so it doesn’t feel too heavy on the palate.
How does fresh mozzarella differ from shredded mozzarella when baked?
Fresh mozzarella has a higher water content and melts into creamy, soft pools. Shredded (low-moisture) mozzarella is saltier and creates that classic, stretchy “cheese pull” and a more even golden crust.
Does using fresh garlic versus jarred garlic change the taste?
Yes. Fresh garlic contains allicin, which provides a sharp, spicy bite. Jarred garlic is much milder and often has an acidic preservative smell that can slightly alter the sauce.
How does the fat content in half-and-half affect the sauce compared to heavy cream?
Half-and-half (10-18% fat) creates a lighter, thinner sauce. Heavy cream (36%+ fat) creates a much thicker, velvety sauce that is less likely to “break” or separate under high heat.
Does crowding the pan with chicken and vegetables affect the cook?
Yes. If the pan is too crowded, the moisture can’t evaporate, causing the food to “steam” rather than roast. Using a large dish ensures the cheese gets brown and the broccoli gets crisp.
Why is 400°F the “magic number” for this dish?
It’s high enough to roast the vegetables and brown the cheese in 20 minutes, while the liquid from the cream protects the chicken from drying out at that speed.
Would searing the chicken beforehand improve the dish?
It would add a “Maillard reaction” (browned crust) for more flavor, but it adds 10-15 minutes to prep. For this specific 10-minute prep recipe, the raw-to-bake method is the priority.
Is the protein-to-fat ratio ideal for muscle growth?
Yes. Chicken provides high-quality lean protein, while the healthy fats from avocado oil and dairy provide the calories needed for energy and recovery.
Why is heavy cream often considered “lower carb” than milk?
Milk contains lactose (milk sugar). Heavy cream is mostly fat with very little lactose remaining, making it the preferred choice for strict keto dieters.
How much fiber is in this serving?
With 2 cups of broccoli and spinach, you are getting roughly 4–6 grams of fiber per serving, which helps with digestion and satiety.
