Step‑by‑Step Instructions for Chicken Zucchini Bake
Step 1: Preheat Your Oven
Begin by preheating your oven to 375°F (190°C). This will ensure it’s hot enough to create that coveted bubbly cheese topping when your Chicken Zucchini Bake is ready to go in. Meanwhile, gather all your ingredients and equipment, including a large skillet, baking dish, and a mixing bowl, to streamline your cooking process.
Step 2: Cook the Chicken
Heat 1 tablespoon of olive oil in a large skillet over medium heat. Once the oil shimmers, add the cubed chicken and cook for about 5–7 minutes, stirring occasionally until it’s golden brown on all sides. Make sure the chicken is cooked through, then remove it from the skillet and set it aside on a plate to cool briefly.
Step 3: Prepare the Vegetables
In a mixing bowl, combine the sliced zucchinis and diced bell peppers. Sprinkle in the garlic powder, onion powder, oregano, basil, salt, and black pepper before drizzling the remaining tablespoon of olive oil over the mixture. Toss everything together until the vegetables are evenly coated; this will enhance the flavor of your Chicken Zucchini Bake.
Step 4: Layer the Vegetables
Spread half of the vegetable mixture at the bottom of a greased baking dish. This creates a flavorful base that will soak up the delicious juices during baking. Make sure the vegetables are evenly distributed to ensure uniform cooking throughout your Chicken Zucchini Bake.
Step 5: Add the Chicken and Sauce
Carefully layer the browned chicken over the vegetables in the baking dish. Then, pour the marinara sauce over the chicken, spreading it out gently with a spatula to cover it well. This provides moisture and adds a lovely depth of flavor to your bake.
Step 6: Top with Remaining Vegetables
Next, layer the remaining vegetable mixture over the chicken and marinara. This will ensure the entire dish is bursting with flavors from the fresh veggies. Try to distribute the vegetables evenly to achieve a balanced taste in every bite of your Chicken Zucchini Bake.
Step 7: Sprinkle the Cheeses
Now it’s time for the cheese! Generously sprinkle the shredded mozzarella and grated Parmesan cheese evenly over the entire mixture. This cheesy topping will melt into a delicious, gooey blanket that holds all the flavors together beautifully as it bakes.
Step 8: Bake the Dish
Cover your Chicken Zucchini Bake with aluminum foil and place it in the preheated oven. Bake for about 20 minutes, ensuring that the dish gets heated through. After that, carefully remove the foil and bake for an additional 10–15 minutes until the cheese is golden and bubbling—your kitchen will smell utterly divine!
Step 9: Rest and Serve
Once out of the oven, allow the Chicken Zucchini Bake to rest for about 5 minutes before serving. This resting time allows the flavors to meld together while slightly cooling, making it easier to portion out. Get ready to share a warm, hearty dish that everyone at the table will love!
