Ingredients
Makes 4-6 servings
For the Chicken & Base
- 2 tablespoons olive oil, divided
- 1.5 lbs boneless, skinless chicken breasts or thighs, cut into 1-inch cubes
- 1 large onion, chopped
- 2 cloves garlic, minced
- 1 red bell pepper, deseeded and chopped
- 1 yellow bell pepper, deseeded and chopped
- 1 (14.5 ounce) can diced tomatoes, undrained
- 1/2 cup pitted Kalamata olives, halved
- 1/4 cup fresh parsley, chopped (plus more for garnish)
- 1 teaspoon dried oregano
- 1/2 teaspoon dried basil
- Salt and freshly ground black pepper to taste
For the Topping
- 1/2 cup crumbled feta cheese
Step-by-Step Instructions
-
Step 1: Prepare Your Ingredients
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. This ensures nothing sticks and makes for easier cleanup later.
Small tip: Use a dish that’s not too shallow to prevent any juices from overflowing during baking.
-
Step 2: Sear the Chicken
Heat 1 tablespoon of olive oil in a large skillet or oven-safe pot over medium-high heat. Add the chicken cubes and cook for 3-5 minutes, or until lightly browned on all sides. The chicken doesn’t need to be fully cooked through yet.
Small tip: Browning the chicken adds a wonderful depth of flavor to the casserole. Do not overcrowd the pan; cook in batches if necessary.
-
Step 3: Sauté Aromatics and Peppers
Remove the chicken from the skillet and set aside. Add the remaining 1 tablespoon of olive oil to the same skillet. Add the chopped onion and cook for about 3-4 minutes, until softened and translucent. Stir in the minced garlic and chopped bell peppers.
Small tip: Cooking the garlic for just a minute helps release its aroma without burning it, which can make it bitter.
-
Step 4: Combine the Casserole Base
Cook the vegetables for another 5-7 minutes, until the peppers start to soften slightly. Stir in the undrained diced tomatoes, Kalamata olives, fresh parsley, dried oregano, and dried basil. Season generously with salt and pepper.
Small tip: Taste the sauce before adding the chicken to adjust seasonings. Remember olives and feta are salty, so go easy on the initial salt.
-
Step 5: Add Chicken Back In
Return the seared chicken to the skillet with the vegetable and tomato mixture. Stir everything gently to combine, ensuring the chicken is well coated with the flavorful sauce. This step ensures all ingredients are evenly distributed.
Small tip: Ensure the chicken is nestled into the sauce to keep it moist during baking.
-
Step 6: Transfer to Baking Dish
Carefully pour the entire mixture from the skillet into your prepared 9×13 inch baking dish. Spread it out evenly with a spoon or spatula. Make sure the chicken and vegetables are in a single layer for even cooking.
Small tip: Use a silicone spatula to scrape every last bit of delicious sauce from the skillet into the baking dish.
-
Step 7: Bake the Casserole
Bake in the preheated oven for 25 minutes. The casserole should be bubbling gently, and the chicken almost cooked through. This initial bake allows the flavors to meld beautifully.
Small tip: You can cover the casserole loosely with foil for the first part of baking if you prefer a very moist result and want to prevent too much browning on top.
-
Step 8: Add Feta and Finish Baking
Remove the casserole from the oven. Sprinkle the crumbled feta cheese evenly over the top of the hot mixture. Return the casserole to the oven and bake for another 10-15 minutes, or until the chicken is fully cooked (internal temperature of 165°F/74°C) and the feta is lightly golden and bubbly.
Small tip: If you like a crispier feta topping, you can switch your oven to broiler mode for the last 2-3 minutes, but watch it very carefully to prevent burning!
-
Step 9: Rest and Serve
Once done, remove the casserole from the oven and let it rest for 5-10 minutes before serving. This resting period allows the juices to redistribute, making the chicken even more tender. Garnish with extra fresh parsley if desired.
Small tip: Resting also makes it easier to serve without everything falling apart.
Tips & Variations
- Gluten-Free Option: This recipe is naturally gluten-free! Just ensure all your ingredients (like canned tomatoes) are certified gluten-free if you have severe allergies.
- Vegan or Vegetarian Option: Easily swap the chicken for 1.5 lbs of firm tofu (pressed, cubed, and pan-fried until golden) or a can of drained chickpeas. You can also add extra vegetables like zucchini or eggplant for more bulk. Omit the feta or use a plant-based feta alternative.
- More Vegetables or Protein: Feel free to add more veggies! Sliced zucchini, eggplant, or a handful of fresh spinach wilted into the sauce would be delicious. For extra protein, stir in a can of cannellini beans or garbanzo beans (chickpeas) with the tomatoes.
- Spicy Version: For a kick, add 1/2 teaspoon of red pepper flakes with the garlic, or include a finely diced jalapeño or serrano pepper with the bell peppers. A pinch of smoked paprika can also add a lovely smoky heat.
- Flavor Boost: A squeeze of fresh lemon juice over the finished casserole brightens all the flavors. You can also add a few capers with the olives for an extra briny punch.
