High protein chicken zucchini bake is the dinner I make when I want something comforting and filling without the heaviness of a pasta bake or the time commitment of something more complicated. Golden-seared chicken pieces layered with thinly sliced zucchini, bound together in a creamy Greek yogurt and egg mixture, and finished with bubbling mozzarella and Parmesan. It is the kind of dish that looks like it took real effort but comes together in 55 minutes with one baking dish and very little cleanup.
I first made this on a Wednesday night when I needed something that would actually satisfy my family but still fit into a low-carb week. My kids were skeptical about the zucchini, but the golden cheese on top got them to the table fast. The dish came out of the oven smelling like something between a savory gratin and a cheesy chicken casserole, and there were no leftovers. That was the first sign I had something worth repeating.
This high protein chicken zucchini bake delivers 48 grams of protein per serving, is naturally gluten-free, and reheats beautifully all week for meal prep. Your family will thank you.

Ingredients for High Protein Chicken Zucchini Bake
Everything here is straightforward and easy to find at any grocery store. I always use Greek yogurt rather than regular yogurt in baked dishes like this because regular yogurt is too thin and releases too much liquid during baking, which can make the layers wet rather than creamy and set.
Chicken and Seasoning
1 lb boneless skinless chicken breast, cut into bite-sized pieces
1 tsp dried oregano
1 tsp smoked paprika – I recommend smoked paprika over sweet here because it adds a subtle savory depth to the chicken that carries through the cheese layers
1/2 tsp garlic powder
1/2 tsp salt, plus more to taste
Freshly ground black pepper to taste
Vegetables
2 medium zucchini, thinly sliced about 1/4 inch thick (about 4 cups) – My preference is consistent 1/4-inch slices because uneven thickness is one of the most common reasons some layers cook through while others stay underdone
1 small yellow onion, finely chopped
2 cloves garlic, minced
Dairy and Eggs
2 large eggs
1/2 cup plain Greek yogurt – In my experience, full-fat Greek yogurt produces a creamier binder than non-fat, but either works as long as it is thick and properly strained
1 cup shredded low-fat mozzarella cheese, divided
2 tbsp grated Parmesan cheese
Other
1 tbsp olive oil, plus extra for greasing the baking dish
I recommend prepping all vegetables and whisking the yogurt-egg binder before you start cooking so assembly moves quickly once the chicken is seared. In my experience, having everything ready before the skillet gets hot is what keeps this recipe feeling manageable on a busy weeknight.
Step 1: Preheat the oven to 375 degrees F. Lightly grease a 9×9-inch baking dish with olive oil and set aside.
Step 2: In a medium bowl, combine oregano, smoked paprika, garlic powder, 1/2 tsp salt, and black pepper. Add the chicken pieces and toss until every piece is evenly coated in the spice mixture.
Step 3: Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add the seasoned chicken and sear for 3 to 4 minutes per side until golden brown on the outside. The chicken does not need to be fully cooked through at this point since it will finish baking in the oven. Transfer to a plate. Do not skip this step. The golden crust that forms during searing is what gives the whole dish its savory depth and keeps the chicken from tasting bland after baking.
Step 4: Reduce the skillet heat to medium. Add the chopped onion to the same pan and saute for about 3 minutes until softened and translucent. Add the minced garlic and cook for 30 seconds, stirring constantly so it does not burn. Return the seared chicken to the skillet, stir to combine with the onion and garlic, and remove from heat.
Step 5: In a separate bowl, whisk together the eggs and Greek yogurt until completely smooth with no visible egg streaks. Season lightly with salt and pepper. If your zucchini slices look particularly moist, pat them dry with a paper towel now before assembling. Wet zucchini releases steam during baking that can pool at the bottom of the dish and make the lower layers watery rather than set.
Step 6: Layer half of the sliced zucchini in the bottom of the prepared baking dish. Spread half of the chicken and onion mixture over the zucchini. Pour half of the yogurt-egg mixture evenly over the top, then sprinkle with half of the mozzarella and half of the Parmesan. Repeat all layers with the remaining zucchini, chicken mixture, and yogurt-egg mixture, and finish with the remaining mozzarella and Parmesan across the top.
Step 7: Cover the dish loosely with foil and bake for 20 minutes. Remove the foil and bake for an additional 10 to 15 minutes until the cheese is fully melted, bubbly, and lightly golden at the edges. Let the bake rest for 5 full minutes before slicing. This rest allows the egg mixture to set so the layers hold together cleanly when you cut and serve rather than sliding apart on the plate.
What to Serve with High Protein Chicken Zucchini Bake
The best sides for this bake add freshness or crunch to balance the creamy, cheesy layers without adding unnecessary carbs or competing with the bold seasoned chicken flavor.
Simple Arugula Salad: Peppery arugula with fresh lemon juice and a light drizzle of olive oil is the cleanest contrast you can put next to a rich, cheesy bake. The slight bitterness cuts through the creaminess of the yogurt-egg layer in a way that feels intentional and refreshing with every bite.
One Pan Greek Vegetables: This one-pan Greek vegetable side is one of the most natural pairings for this chicken zucchini bake. The Mediterranean herb flavors complement the oregano and smoked paprika in the chicken directly, and both dishes finish in the oven so serving them together on a weeknight requires almost no extra work.
Garlic Roasted Vegetables: A pan of garlic-roasted seasonal vegetables adds color, fiber, and a savory caramelized depth that works beautifully alongside the creamy baked layers. Roast them at the same oven temperature as the bake and pull both dishes at the same time for an effortless complete dinner.
Crispy Oven Roasted Cauliflower: Cauliflower roasted until the edges caramelize and crisp adds a nutty, satisfying side that keeps the meal low-carb and gluten-free to match the bake’s nutritional profile. It is mild enough not to compete with the smoked paprika and oregano seasoning and adds a pleasing crunch contrast to the soft, layered bake.
Honey Glazed Carrots and Green Beans: For a slightly sweeter vegetable side that balances the savory richness of the bake, these honey glazed carrots and green beans add natural sweetness and bright color to the plate. They cook quickly on the stovetop while the bake is in the oven and round out the table with a vibrant, family-friendly side.
Garlic Bread with Sliced Bread: For anyone at the table who is not strictly low-carb, a warm slice of garlic bread is perfect for scooping up the creamy yogurt-egg binder that pools around the edges of each serving. It takes 10 minutes and turns a nutritious dinner into something that feels a little more indulgent without changing the main dish at all.
Mediterranean Chickpea Salad with Lemon Vinaigrette: A light, bright chickpea salad with lemon vinaigrette adds plant-based protein and a tangy, fresh contrast to the warm, cheesy bake. The Mediterranean herb notes in the salad echo the oregano in the chicken seasoning and make the full plate feel cohesive rather than assembled at random.
How to Store and Reheat High Protein Chicken Zucchini Bake
Store leftover bake in an airtight container in the refrigerator for up to 4 days. Let it cool completely before sealing to prevent condensation from softening the top cheese layer. I recommend cutting into individual portions before refrigerating since single slices cool faster and reheat more evenly than a large section of the dish.
To reheat, I recommend the oven at 350 degrees F covered loosely with foil for about 15 minutes until heated through and the cheese is soft and melted again. The microwave works for single portions on medium power in 90-second intervals. Avoid high microwave power, which tends to make the egg layer rubbery and dry out the chicken quickly.
Pro tip: you can assemble this high protein chicken zucchini bake up to 24 hours ahead and refrigerate it unbaked, covered tightly. When ready to cook, add 5 to 10 extra minutes to the covered bake time since the dish will be cold going into the oven. You can also freeze the assembled unbaked dish wrapped tightly for up to 3 months, thawing overnight in the refrigerator before baking.
FAQs
Can I use chicken thighs instead of chicken breast?
Yes. Boneless skinless chicken thighs work well and stay juicier than breast meat during the bake. Cut them into the same bite-sized pieces and use the same seasoning and searing method. The slightly higher fat content in thighs adds richness to the layers that pairs well with the Greek yogurt binder.
Can I substitute the Greek yogurt with something else?
Blended low-fat cottage cheese is the best substitute. Blend it completely smooth before whisking with the eggs so there are no lumps in the binder. Regular yogurt is too thin and will release too much liquid during baking. Sour cream also works but adds more fat to the nutritional profile per serving.
How do I prevent the zucchini from making the bake watery?
Slice the zucchini consistently at about 1/4 inch and pat the slices dry with a paper towel before assembling if they look moist. For very fresh, water-heavy zucchini, salt the slices lightly, let them sit for 10 minutes, then pat completely dry before layering. This draws out excess moisture before it can pool at the bottom of the dish during baking.

Method
Preheat oven to 375 degrees F. Lightly grease a 9×9-inch baking dish with olive oil and set aside.
In a medium bowl, combine oregano, smoked paprika, garlic powder, salt, and black pepper. Add chicken pieces and toss until evenly coated.
Heat 1 tbsp olive oil in a large skillet over medium-high heat. Sear chicken for 3 to 4 minutes per side until golden brown. Chicken does not need to be fully cooked through at this stage. Transfer to a plate.
Reduce skillet heat to medium. Add chopped onion and saute for about 3 minutes until softened. Add minced garlic and cook for 30 seconds stirring constantly. Return chicken to skillet, stir to combine, and remove from heat.
In a separate bowl, whisk together eggs and Greek yogurt until completely smooth. Season lightly with salt and pepper. Pat zucchini slices dry with a paper towel if they appear moist.
Layer half the zucchini slices in the bottom of the prepared baking dish. Spread half the chicken mixture over the zucchini. Pour half the yogurt-egg mixture evenly over the top. Sprinkle with half the mozzarella and half the Parmesan. Repeat all layers and finish with remaining cheese on top.
Cover loosely with foil and bake for 20 minutes. Remove foil and bake for an additional 10 to 15 minutes until cheese is melted, bubbly, and lightly golden. Let rest 5 minutes before slicing and serving.
Notes
Do not skip searing the chicken; the golden crust adds savory depth to the whole dish. Use Greek yogurt only; regular yogurt releases too much liquid during baking. Slice zucchini consistently at about 1/4 inch for even cooking. Pat zucchini dry if very moist to prevent watery layers. Assemble up to 24 hours ahead unbaked and refrigerate; add 5 to 10 minutes to covered bake time. Freeze assembled unbaked dish for up to 3 months; thaw overnight before baking.
