Instructions
Step 1: Prepare the Zucchini (The Secret to No Soggy Bake!)
-
Place the sliced zucchini in a large colander set over a bowl or in the sink. Sprinkle with 1 tablespoon of salt and toss to coat.
-
Let it sit for 15-20 minutes. This process, called “sweating,” draws out the excess water. After 20 minutes, you’ll see beads of moisture on the zucchini.
-
Rinse the zucchini slices thoroughly under cold water to remove the excess salt, then pat them extremely dry with a clean kitchen towel or paper towels. This drying step is crucial.
Step 2: Sear the Chicken
-
While the zucchini is sweating, pat the chicken pieces dry with a paper towel. Season them with 1/2 teaspoon salt, pepper, and paprika.
-
Heat 1 tablespoon of olive oil in a large, oven-safe skillet (like a cast-iron or stainless steel pan) over medium-high heat.
-
Add the chicken in a single layer (cook in batches if necessary to avoid overcrowding). Sear for 4-5 minutes, until golden brown on one side. Flip and cook for another 3-4 minutes until cooked through. The chicken doesn’t need to be fully cooked through at this point, as it will finish in the oven, but it should be opaque.
-
Use a slotted spoon to transfer the seared chicken to a plate and set aside. Don’t clean the pan; those browned bits are flavor!
Step 3: Sauté the Zucchini
-
In the same skillet, add the remaining 1 tablespoon of olive oil.
-
Add the dried zucchini slices and the first amount of minced garlic. Sauté for 3-4 minutes, just until the zucchini starts to soften slightly and get a little color. Remove the zucchini from the pan and set aside with the chicken.
Step 4: Make the Creamy Garlic Sauce
-
Reduce the heat to medium. In the same skillet, melt the butter. Add the remaining 3 cloves of minced garlic and sauté for about 30-60 seconds until fragrant, being careful not to burn it.
-
Pour in the chicken broth and scrape the bottom of the pan with a wooden spoon to deglaze, lifting up all those delicious browned bits. Let it simmer for 2-3 minutes until it reduces slightly.
-
Reduce heat to low. Pour in the heavy cream and add the cubed cream cheese. Whisk continuously until the cream cheese has completely melted and the sauce is smooth.
-
Whisk in the grated Parmesan cheese until melted and the sauce has thickened slightly. Taste and adjust seasoning with salt and pepper if needed. (Remember the chicken and zucchini already have salt, so you may not need much).
Step 5: Assemble and Bake
-
Preheat your oven to 190°C (375°F).
-
If your skillet is oven-safe, add the chicken and zucchini back into the skillet with the sauce and stir gently to combine everything. If not, transfer the sauce to a lightly greased 9×9-inch (or similar size) baking dish, then add the chicken and zucchini and stir.
-
Smooth the mixture into an even layer. Sprinkle the shredded mozzarella cheese evenly over the top.
-
Transfer the skillet or baking dish to the preheated oven. Bake, uncovered, for 15-20 minutes, or until the casserole is hot and bubbly and the cheese on top is melted and golden brown. For a browner top, switch the oven to broil for the last 1-2 minutes, watching closely to prevent burning.
Step 6: Rest and Serve
-
Remove from the oven and let it rest for at least 5-10 minutes. This allows the casserole to set, making it easier to serve.
-
Garnish with fresh chopped parsley or chives. Serve warm on its own or with a side salad.
Tips for Recipe Success
-
Don’t Skip the Zucchini Prep: This is the most important step. Removing the moisture prevents your creamy bake from turning into a soup.
-
Cut Even Pieces: Try to cut your chicken and zucchini into similar-sized pieces to ensure they cook evenly.
-
Cheese Matters: For the best melt, buy a block of mozzarella and shred it yourself. Pre-shredded cheese contains starches and anti-caking agents that prevent it from melting as smoothly.
Storage & Reheating
-
Fridge: Store leftovers in an airtight container in the refrigerator for up to 4 days.
-
Reheat: Reheat gently in the microwave or in a 175°C (350°F) oven until warmed through.
-
Freezer: This casserole freezes well. Assemble the bake (without the final baking step) in a freezer-safe dish, cover tightly, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed.
