Ingredients

Main Ingredients

• 4 boneless, skinless chicken breasts (or thighs)
• 2 tbsp olive oil (or butter)
• 2 cups mushrooms, sliced (white or cremini)
• 3 cups fresh spinach leaves
• 3 cloves garlic, minced
• 1 small onion, diced
• 1 cup heavy cream
• ½ cup chicken broth
• ½ cup shredded mozzarella cheese
• ¼ cup grated Parmesan cheese
• 1 tsp Italian seasoning
• ½ tsp paprika
• Salt and pepper to taste
• Fresh parsley (for garnish)

Instructions

1. Preheat Oven:
   Preheat your oven to 375°F (190°C). Lightly grease a baking dish with olive oil or non-stick spray.
2. Prepare the Chicken:
   Season chicken breasts with salt, pepper, paprika, and Italian seasoning on both sides. Heat olive oil in a skillet over medium-high heat. Sear the chicken for 3–4 minutes per side until golden brown (it will finish cooking in the oven). Transfer to a plate.
3. Cook the Vegetables:
   In the same skillet, sauté diced onions for 2 minutes until translucent. Add minced garlic and sliced mushrooms; cook for another 3–4 minutes until softened and lightly browned.
4. Add the Spinach:
   Toss in the fresh spinach and cook until wilted. Remove from heat.
5. Make the Cream Sauce:
   Pour in the heavy cream and chicken broth. Stir to deglaze the pan, scraping up browned bits. Simmer for 2–3 minutes until slightly thickened. Stir in half the Parmesan cheese.
6. Assemble the Dish:
   Arrange the seared chicken breasts in the baking dish. Pour the creamy mushroom-spinach mixture over the top. Sprinkle with mozzarella and remaining Parmesan.
7. Bake:
   Bake uncovered for 20–25 minutes until the cheese is melted and bubbly, and the chicken is cooked through (internal temperature 165°F / 74°C).
8. Garnish & Serve:
   Let the dish rest for 5 minutes. Sprinkle with fresh parsley and serve warm.

Notes

For extra flavor, add a layer of crispy bacon or a handful of sun-dried tomatoes before baking.

Tips for Perfect Results

• Don’t skip searing: Browning the chicken first locks in moisture and flavor.
• Use full-fat cream: For the best texture and rich flavor, go for heavy cream, not milk.
• Try different cheeses: Mozzarella melts beautifully, but Gruyère or provolone adds a gourmet touch.
• Balance the sauce: If the sauce feels too thick, thin it slightly with more chicken broth.
• Add a crispy topping: Sprinkle crushed pork rinds or almond flour before baking for crunch.

Low-Carb Pairing Ideas

Even though this dish is satisfying on its own, you can round out your meal with:

• Cauliflower mash – a creamy, buttery side that’s the perfect potato substitute.
• Zucchini noodles – for extra texture and a pasta-like experience.
• Steamed asparagus or broccoli – to add greens and freshness.
• Simple garden salad – with olive oil and lemon dressing.

Variations

• Spicy twist: Add red pepper flakes or a dash of cayenne for gentle heat.
• Mediterranean version: Toss in sun-dried tomatoes and crumbled feta instead of mozzarella.
• Bacon lover’s version: Add crumbled cooked bacon to the top before baking.
• Dairy-free: Substitute coconut cream for heavy cream and dairy-free cheese for a vegan-friendly twist.
• Mushroom swap: Try portobello or shiitake mushrooms for an umami boost.

This low-carb chicken bake is ideal for prepping ahead!

• To Store: Refrigerate leftovers in an airtight container for up to 4 days.
• To Freeze: Freeze portions for up to 2 months. Thaw overnight in the fridge before reheating.
