Step‑by‑Step Instructions for Amazing Greek Chicken Casserole Recipe
Step 1: Prep Ingredients
Begin by prepping all your ingredients for the Amazing Greek Chicken Casserole Recipe. Chop one onion and mince 3-4 cloves of fresh garlic. Rinse and dry about four cups of fresh spinach. Having everything ready to go makes the cooking process smoother and more enjoyable, so take a moment to gather your items before you start!
Step 2: Sauté
Heat 2 tablespoons of olive oil in a large skillet over medium heat for about 2 minutes. Once the oil shimmers, add the chopped onion and minced garlic, sautéing until the onion becomes translucent and fragrant—approximately 5 minutes. This step is essential as it builds a flavorful base for your casserole.
Step 3: Combine
Next, stir in the spinach and continue sautéing for an additional 2-3 minutes until it wilts. Then, add in 1 can (about 14.5 ounces) of diced tomatoes, allowing it to heat through for another 3 minutes. The combination of spinach and tomatoes creates a vibrant and nutritious backdrop for your Greek chicken casserole.
Step 4: Mix Base
Carefully add the chicken pieces into the skillet, ensuring each piece is coated with the savory vegetable mixture. Make sure to use bone-in thighs or breasts for added flavor. Cook the mixture for about 5 minutes, letting the chicken absorb the wonderful flavors of the sautéed veggies.
Step 5: Season
Sprinkle a teaspoon of dried oregano, along with salt and black pepper to taste, evenly over the chicken and vegetable mixture. Stir to incorporate the seasonings fully. This foundational step infuses your Amazing Greek Chicken Casserole with the Mediterranean essence that makes it so special.
Step 6: Transfer to Oven
Preheat your oven to 425°F (220°C), then pour the entire mixture into a greased casserole dish. Gently spread it out for even cooking. Top the casserole with about 1 cup of crumbled feta cheese for that signature tangy flavor, making sure the cheese covers the mixture thoroughly.
Step 7: Bake
Place the casserole in the preheated oven and bake for approximately 35 minutes. You’ll know it’s ready when the chicken is fully cooked, juices run clear, and the top is bubbly and golden. This final step melds all the flavors together beautifully while creating a delightful texture.
Step 8: Serve
Once baked, remove the Amazing Greek Chicken Casserole from the oven and let it rest for a few minutes. Garnish with freshly chopped parsley for a burst of color and freshness. Spoon onto plates and serve warm to create a comforting meal that your family will adore!

Make Ahead Options

You can chop the vegetables (onion and garlic) and wash the spinach up to 24 hours in advance, storing them in airtight containers in the refrigerator.
