Helpful Tips
- Use freshly grated cheese: Pre-shredded cheese contains anti-caking agents that prevent it from melting as smoothly as cheese you grate yourself.
- Control the thickness: If you prefer a thicker sauce, you can stir 1 teaspoon of cornstarch mixed with 1 tablespoon of cold water into the heavy cream before adding it to the skillet.
- Variations & Add-ins: Feel free to toss in sliced mushrooms, artichoke hearts, or a handful of kalamata olives for a more Mediterranean flare!
- Lighten it up: For a lighter version, you can substitute half-and-half for heavy cream, but note that the sauce will be slightly thinner.
Step-by-Step Instructions
- Preheat your oven to 375 degrees F (190 degrees C) and lightly grease a 9×13-inch baking dish with non-stick spray or olive oil.
- Season the chicken thigh pieces generously with salt, black pepper, dried oregano, and dried basil.
- Heat olive oil in a large skillet over medium-high heat. Add the chicken pieces and sear until golden brown on all sides, about 5-6 minutes.
- Transfer the seared chicken into the prepared baking dish using a slotted spoon, leaving the drippings in the skillet.
- Reduce heat to medium. Add the diced onion to the skillet and sauté for 3-4 minutes until translucent. Add the minced garlic and chopped sun-dried tomatoes, cooking for another 1 minute.
- Pour in the chicken broth and heavy cream, scraping up any browned bits from the bottom of the pan. Bring to a gentle simmer for 2-3 minutes to let the sauce slightly thicken.
- Stir in the fresh baby spinach and cook until just wilted, about 1-2 minutes, then remove from heat.
- Pour the creamy sauce mixture over the chicken in the baking dish, stirring gently to ensure everything is evenly combined.
- Top the casserole evenly with the shredded mozzarella and grated Parmesan cheese.
- Bake uncovered in the preheated oven for 25-30 minutes, or until the chicken is cooked through and the cheese is bubbly and golden-brown. Let rest for 5 minutes before serving.
