This dish features tender chicken breasts baked in a creamy, cheesy sauce enriched with sun-dried tomatoes and fresh spinach. The combination of Parmesan and mozzarella creates a golden, bubbly top, with Italian seasoning and optional red pepper flakes adding depth. It’s a comforting, low-carb option with a rich texture and vibrant flavors. Garnish with fresh basil to enhance its fresh aroma and serve warm for a satisfying meal.

My sister rolled her eyes when I first told her the name of this dish, but one bite later and she was already planning when to make it for her new boyfriend. The way the sun-dried tomatoes get all sweet and jammy while the cream sauce bubbles into something velvety and golden creates this incredibly rich comfort food that somehow still fits into a low-carb life. I have never seen a casserole disappear so quickly at a dinner party.

Last winter when my roommate was recovering from surgery and needed comfort food that wouldnt derail her health goals, I made this weekly. She started requesting it by that silly name, and soon friends were texting me for the recipe after coming over for dinner. Theres something about the combination of tender chicken, bubbling cheese, and those little concentrated tomato gems that makes people feel taken care of.

Ingredients

  • 4 boneless skinless chicken breasts: Pound them to even thickness so they cook at the same rate, otherwise thinner pieces dry out while thicker ones finish
  • 1 cup heavy cream: This creates the luxurious sauce base and cannot be substituted with milk or the dish will curdle and separate
  • ½ cup grated Parmesan cheese: Use freshly grated for the best melt and flavor, pre-grated has anti-caking agents that make the sauce grainy
  • 1 cup shredded mozzarella cheese: Part-skim works fine but whole milk gives you that gorgeous cheese pull in every bite
  • ½ cup sun-dried tomatoes: Look for ones packed in oil and drain them well, the oil-packed ones have so much more flavor than dry versions
  • 1 cup baby spinach: It wilts down to almost nothing in the sauce so do not be afraid to add extra if you want more greens
  • 2 cloves garlic: Mince it fresh because garlic powder cannot provide the same aromatic backbone to the cream sauce
  • 1 teaspoon Italian seasoning: Homemade blend or store-bought both work, just make sure it is fresh for maximum fragrance
  • ½ teaspoon crushed red pepper flakes: These provide just a gentle warmth that cuts through the richness, but leave them out if you are sensitive to heat
  • Salt and black pepper: Season generously but remember the sun-dried tomatoes and both cheeses are already salty

Instructions

Preheat and prep your baking dish:
Get your oven to 400°F and grease a 9x13-inch dish with butter or oil, this prevents the cheese from creating a stuck-on mess later
Season and arrange the chicken:
Sprinkle both sides of each breast with salt, pepper, and Italian seasoning, then lay them in a single layer so they cook evenly
Make the creamy sauce mixture:
Whisk together the heavy cream, Parmesan, garlic, and red pepper flakes until the cheese is fully dissolved into the cream
Pour the sauce over the chicken:
Drizzle that gorgeous Parmesan cream evenly over all the pieces so every bite gets coated in that rich mixture
Add the vegetables and cheese:
Scatter the sun-dried tomatoes and spinach around the chicken, then blanket everything with the mozzarella
Bake until golden and bubbly:
Slide the dish into the oven for 25 to 30 minutes, watching for the cheese to turn golden brown and the sauce to bubble around the edges
Rest before serving:
Let everything sit for about 5 minutes so the sauce thickens slightly and the chicken juices redistribute, then top with fresh basil if you have it

The first time I made this for a weeknight dinner, my husband actually asked if we could have it again the very next night. There is something about the way the sauce clings to every tender bite of chicken that makes it feel so much more indulgent than it really is. I started keeping sun-dried tomatoes in my pantry just so I could throw this together whenever the craving strikes.

Making It Your Own

Kale works beautifully instead of spinach and holds up a bit better in the sauce without disappearing completely. Provolone gives you a sharper, smokier flavor profile if you want something different from the mild mozzarella. Sometimes I add artichoke hearts when I want to make it feel even more special.

Perfect Pairings

Cauliflower rice soaks up that incredible sauce without adding extra carbs to your meal. A crisp green salad with a bright vinaigrette cuts through all the richness and freshens up your plate. Roasted broccoli or asparagus on the side makes this feel like a complete Sunday dinner.

Storage And Meal Prep

This casserole keeps beautifully in the refrigerator for up to 4 days and actually develops deeper flavor as it sits. I portion it into individual containers right after cooking so I have grab-and-go lunches all week. Reheat gently with a splash of cream to bring the sauce back to life.

  • Freeze portions in airtight containers for up to 3 months if you want to stock your freezer
  • Thaw overnight in the refrigerator and reheat at 350°F until hot all the way through
  • The texture remains surprisingly creamy after freezing, much better than I expected

Recipe Questions

Yes, you can assemble it in advance and refrigerate before baking. Just bake right before serving for best texture.

Kale works well as a substitute, providing a similar texture and flavor profile when cooked.

Searing adds extra flavor and a golden crust but is optional. Baking alone yields tender results.

Yes, modify the amount of crushed red pepper flakes to make it milder or spicier according to your taste.

Cauliflower rice or a fresh side salad pairs well, balancing the rich and savory flavors of the main dish.
