High Protein Chicken Zucchini Bake

My sister texted me a photo of her gym meal prep containers, each one packed with this golden, bubbly bake, and I knew I had to try it. She'd been raving about hitting her protein goals without eating plain grilled chicken every single night. The combination sounded odd at first—Greek yogurt in a bake?—but one forkful and I was completely sold. It's creamy, cheesy, and somehow feels indulgent while checking every nutritional box. Now it's my Sunday ritual, and my freezer is never without a few portions tucked away.

I made this for a potluck with friends who were all on different diets—keto, high-protein, gluten-free—and it was the first dish to disappear. Someone asked if I'd used cream, and I loved revealing the secret was just Greek yogurt and eggs. The zucchini layers softened perfectly, soaking up all the savory flavors without turning mushy. Even my carb-loving husband went back for seconds. It felt like a quiet victory to serve something healthy that no one missed the pasta in.

Ingredients

• Boneless, skinless chicken breast: The lean protein star of the dish; cutting it into bite-sized pieces ensures even cooking and makes every forkful balanced.
• Dried oregano, smoked paprika, and garlic powder: This simple spice trio adds warmth and depth without overwhelming the creamy base.
• Zucchini: Thinly sliced so they soften just enough to meld into the layers while keeping a slight bite and soaking up all the savory goodness.
• Yellow onion and garlic: Sautéed until fragrant, they form the aromatic backbone that makes the whole kitchen smell amazing.
• Eggs and plain Greek yogurt: Whisked together, they create a rich, protein-packed custard that binds the layers and bakes into creamy perfection.
• Low-fat mozzarella and Parmesan: Mozzarella melts into gooey pools, while Parmesan adds a nutty, golden finish on top.
• Olive oil: Just enough to sear the chicken and grease the dish, keeping everything from sticking.
• Fresh parsley or basil: A bright, herbaceous garnish that cuts through the richness and makes it look restaurant-worthy.

Instructions

Prep the oven and dish:

Preheat to 375°F and lightly grease your baking dish with olive oil so nothing sticks. This step sets you up for easy cleanup later.

Season the chicken:

Toss the chicken pieces in oregano, smoked paprika, garlic powder, salt, and pepper until every piece is coated. The spices will create a flavorful crust when seared.

Sear the chicken:

Heat olive oil in a large skillet over medium-high and cook the chicken 3–4 minutes per side until golden. It doesn't need to be fully cooked yet; it'll finish in the oven.

Sauté the aromatics:

Lower the heat to medium, add the chopped onion, and cook until softened, about 3 minutes. Stir in the garlic and let it bloom for 30 seconds, filling your kitchen with that irresistible smell.

Make the yogurt-egg mixture:

Whisk together the eggs and Greek yogurt until smooth and creamy. Season lightly with salt and pepper; this will be the silky binder for your layers.

Combine chicken and aromatics:

Return the seared chicken to the skillet with the onion and garlic, stirring to coat everything. Remove from heat so it doesn't overcook.

Layer the bake:

Start with half the zucchini slices in the baking dish, then half the chicken mixture, half the yogurt-egg blend, and half the cheeses. Repeat the layers, finishing with a generous sprinkle of mozzarella and Parmesan on top.

Bake covered:

Cover loosely with foil and bake for 20 minutes to cook through without drying out. The foil traps moisture and keeps everything tender.

Finish uncovered:

Remove the foil and bake another 10–15 minutes until the cheese is melted, bubbly, and lightly golden. The top should look irresistible.

Rest and serve:

Let the bake rest for 5 minutes before slicing; this helps it set and makes serving cleaner. Garnish with fresh herbs and dig in while it's warm.

Pin It

The first time I reheated a portion for lunch at work, a coworker leaned over and asked what smelled so good. I handed her the recipe on a scrap of paper, and by the next week, three people in the office were meal-prepping it. It became our unofficial Monday motivation, proof that eating well doesn't have to mean boring tupperware salads. There's something quietly satisfying about a dish that fuels your body and actually tastes like comfort food.

Storage and Reheating

This bake keeps beautifully in an airtight container in the fridge for up to four days, and the flavors deepen as it sits. I portion it out into individual containers right after it cools, so grabbing lunch is effortless all week. Reheat in the microwave for 1–2 minutes, or pop it in a 350°F oven for 10 minutes if you want the cheese to get bubbly again. You can also freeze individual portions for up to two months; just thaw overnight in the fridge before reheating. It's one of those rare dishes that actually improves your future self's life.

Customization Ideas

I've swapped Greek yogurt for cottage cheese when I'm out, and it adds a slightly tangier, curdled texture that some people love even more. If you're craving heat, a pinch of red pepper flakes in the chicken or a drizzle of hot sauce before serving wakes everything up. Stirring in chopped bell peppers or a handful of baby spinach with the onions sneaks in extra veggies without changing the feel of the dish. For a dairy-free version, plant-based yogurt and cheese alternatives work surprisingly well, though the texture will be a bit lighter. Sometimes I top it with sliced tomatoes before the final bake for a fresh, juicy contrast.

Serving Suggestions

This bake is hearty enough to stand alone, but I love serving it with a crisp green salad dressed in lemon vinaigrette to balance the richness. A slice of crusty whole-grain bread on the side is perfect for anyone not watching carbs, and it soaks up any extra yogurt mixture beautifully. For a full meal-prep situation, I pair it with roasted broccoli or steamed green beans. It also works as a impressive centerpiece for a casual dinner party, especially when you garnish it generously with fresh herbs.

• Serve with a simple arugula salad tossed in olive oil and balsamic for a peppery contrast.
• Pair with roasted cherry tomatoes on the side for a burst of sweetness.
• Top each portion with a dollop of pesto or tzatziki for extra Mediterranean flair.

Every time I pull this bubbling, golden dish out of the oven, I'm reminded that healthy eating doesn't have to feel like sacrifice. It's become my proof that you can fuel your body well and still look forward to every single bite.
