Ingredients You Need
Protein and veggies
- 1.5 pounds boneless skinless chicken breast, cut in small bite-size cubes
- Use thighs if you prefer more flavor and moisture.
- 3 medium zucchini, halved lengthwise and sliced into half moons
- 1 small yellow onion, finely diced
- 3 cloves garlic, minced
- 1 red bell pepper, diced (adds sweetness and color)
Sauce and binder
- 1 cup plain Greek yogurt, 2% or nonfat
- Greek yogurt keeps protein high and adds creaminess without heavy cream.
- 1/2 cup low fat cottage cheese, blended smooth or left slightly chunky
- 1/2 cup low sodium chicken broth
- 2 tablespoons olive oil
- 2 tablespoons grated Parmesan cheese
- 1 cup shredded part skim mozzarella cheese, divided
- 2 tablespoons tomato paste or thick marinara
- 1 tablespoon Dijon mustard
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- 1 teaspoon Italian seasoning
- 1/2 teaspoon smoked paprika
- 1/4 teaspoon red pepper flakes, optional for heat
Topping
- 1/4 cup whole wheat panko or regular breadcrumbs
- 1 tablespoon grated Parmesan
- 1 teaspoon olive oil
- 1 teaspoon dried parsley or Italian seasoning
Pantry shortcuts and brand notes
- Use rotisserie chicken or leftover grilled chicken to save time; just shred about 3 cups.
- Jarred minced garlic works in a pinch, though fresh garlic gives brighter flavor.
- Any good quality store brand Greek yogurt works; avoid sweetened versions.
- Use pre shredded mozzarella if you need speed, but hand shredded cheese melts smoother.
Equipment list
- 9×13 inch baking dish
- Large skillet
- Mixing bowls
- Whisk and wooden spoon
- Cutting board and sharp knife
- Small blender or immersion blender if you want ultra smooth cottage cheese
Tips & Mistakes
- Salt the zucchini lightly and pat it dry before cooking to avoid a watery bake.
- Cut chicken in even small cubes so it cooks through at the same time.
- Brown the chicken lightly in the skillet to build flavor instead of tossing it in raw.
- Do not overcook the zucchini in the skillet; keep it slightly crisp so it holds texture in the oven.
- Use hot broth when you whisk the sauce to help the yogurt blend smoothly and avoid lumps.
- Spread the mixture in an even layer in the baking dish so it bakes uniformly.
- Add the breadcrumb topping near the end if your oven browns quickly, so it does not burn.
- Let the bake rest 5 to 10 minutes before cutting so the sauce thickens and slices hold together.
How to Make High Protein Chicken Zucchini Bake
1: Prep the veggies and chicken
Preheat your oven to 400°F and lightly grease a 9×13 inch baking dish. Slice the zucchini into half moons about 1/4 inch thick so they cook quickly but still keep some bite. Dice the onion and bell pepper, and mince the garlic.
Cut the chicken into small cubes about 3/4 inch across. Pat the chicken dry with paper towels so it browns instead of steams in the skillet.
2: Sweat the zucchini
Place the sliced zucchini in a colander and sprinkle with a pinch of salt. Toss and let it sit for 10 minutes while you start the chicken. This step pulls out extra moisture and keeps the high protein chicken zucchini bake recipe from turning soupy.
After 10 minutes, pat the zucchini dry with a clean towel or paper towels. You do not need to rinse it.
3: Brown the chicken
Heat 1 tablespoon olive oil in a large skillet over medium high heat. Add the chicken in a single layer and season with a pinch of salt and pepper. Cook and stir until the chicken loses its pink color and browns in spots, about 5 to 7 minutes.
The chicken does not need to cook fully in the skillet, since it finishes in the oven. Transfer the browned chicken to a large mixing bowl.
4: Sauté the veggies
In the same skillet, add the remaining 1 tablespoon olive oil. Toss in the onion and bell pepper and cook until they soften and turn slightly golden, about 4 to 5 minutes. Add the garlic and cook 30 seconds, so it smells fragrant but does not burn.
Add the patted dry zucchini to the skillet. Cook 3 to 4 minutes, just until it starts to soften, then remove from heat.
5: Mix the sauce
In a medium bowl, whisk together Greek yogurt, cottage cheese, chicken broth, tomato paste, Dijon mustard, 2 tablespoons Parmesan, half of the mozzarella, Italian seasoning, smoked paprika, red pepper flakes, salt, and pepper. If you want a smoother texture, blend the cottage cheese with a splash of broth before you add it. Taste the sauce and adjust salt or spices to your liking.
You want a thick but pourable sauce that coats the back of a spoon. Add a splash more broth if it feels too thick.
6: Combine everything
Add the sautéed veggies to the bowl with the browned chicken. Pour the sauce over the top. Stir gently until the chicken and veggies look well coated.
Transfer the mixture to the prepared baking dish and spread it in an even layer. Sprinkle the remaining mozzarella evenly over the surface.
7: Add the crunchy topping
In a small bowl, mix the panko, 1 tablespoon Parmesan, dried parsley, and 1 teaspoon olive oil. Toss until the crumbs feel lightly coated. Sprinkle this mixture over the cheesy layer.
This topping adds texture and makes the high protein chicken zucchini bake recipe feel extra satisfying.
8: Bake
Place the baking dish in the preheated oven. Bake for 20 to 25 minutes, until the cheese melts and bubbles and the topping turns golden. Check the center to make sure the chicken reaches 165°F.
If the top browns too quickly, tent the dish loosely with foil during the last few minutes. Let the bake rest 5 to 10 minutes on the counter before serving.
Variations I’ve Tried
Swap the chicken for ground turkey and cook it in the skillet with the onion and pepper for a slightly different flavor and texture. Use shredded rotisserie chicken and skip the browning step when you feel short on time. Stir in a cup of cooked quinoa or brown rice for extra carbs and bulk if you feed hungry teens or athletes.
Change the flavor profile with taco seasoning instead of Italian seasoning and top with a sprinkle of cheddar. Add mushrooms or spinach to sneak in more veggies, just sauté them with the onion. Use lactose free Greek yogurt and cheese if you need a friendlier option for sensitive stomachs.
How to Serve High Protein Chicken Zucchini Bake
Serve this high protein chicken zucchini bake recipe hot from the oven with a simple green salad or sliced cucumbers on the side. Spoon it over cauliflower rice or brown rice for a more filling plate. Pair it with garlic roasted potatoes or whole grain pasta when you want extra carbs.
Kids often like it with a side of warm bread and carrot sticks. I also pack leftovers in meal prep containers with steamed green beans or roasted broccoli for quick lunches.
How to store
- Fridge: Cool the bake completely, then cover the dish tightly or portion into airtight containers and store in the fridge for up to 4 days.
- Freezer (whole): Wrap the cooled baking dish in plastic wrap, then foil, and freeze for up to 2 months.
- Freezer (portions): Slice into single servings, wrap each piece, place in a freezer bag or container, and freeze for up to 3 months.
- Reheat: Reheat in the oven at 350°F, covered, for 15 to 20 minutes until hot, or microwave individual portions in 60 to 90 second bursts, stirring halfway so the chicken heats evenly and the sauce stays creamy.
