1. Preheat your oven to 375°F (190°C). Lightly grease a baking dish large enough to hold the chicken breasts in a single layer.
2. Heat the olive oil in a large skillet over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant—this always reminds me of my grandmother’s kitchen, where garlic was the secret to everything delicious.
3. Add the fresh spinach to the skillet and cook, stirring occasionally, until wilted, about 3-4 minutes. Remove from heat and let it cool slightly.
4. In a medium bowl, combine the ricotta, Parmesan, half of the mozzarella, Italian seasoning, red pepper flakes (if using), and a pinch of salt and pepper. Stir in the cooked spinach and mix until well incorporated.
5. Season the chicken breasts generously with salt and pepper on both sides. Place them in the prepared baking dish.
6. Spoon the ricotta and spinach mixture evenly over the chicken breasts, spreading it gently to cover each piece.
7. Pour the heavy cream (or milk) around the chicken in the dish—this helps keep everything moist and creates a lovely sauce as it bakes.
8. Sprinkle the remaining mozzarella cheese over the top of the ricotta mixture.
9. Bake uncovered for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is golden and bubbly.
10. For a beautiful finish, switch the oven to broil and cook for an additional 2-3 minutes, watching carefully so it doesn’t burn.
11. Remove from the oven and let rest for 5 minutes. Before serving, drizzle with fresh lemon juice if you want a bit of brightness to cut through the richness.

One thing I’ve learned as a busy mom is that resting meat is a game changer—it keeps everything juicy and tender. Plus, letting the bake sit for a few minutes means you can sneak in a quick tidy-up or set the table without rushing.
