What You’ll Need

• 800 g (1 ¾ lb) boneless skinless chicken thighs, cut into 2 cm (¾‑inch) cubes: We’re using chicken thighs here for their rich flavor and ability to stay juicy during baking. Chicken thighs are also a fantastic source of protein, essential for muscle building and overall health. You can trim any excess fat before cubing.
• 2 large zucchinis (≈600 g / 1 ⅓ lb), sliced into half‑moons 0.5 cm (¼‑inch) thick: Zucchini provides a mild, slightly sweet flavor and a wonderful texture. Choosing zucchinis that are firm and relatively small will give you the best results. The half-moon shape ensures even cooking.
• 1 medium red onion (≈150 g / 5 oz), finely diced: Red onion adds a lovely sharpness and subtle sweetness to the bake. Dicing it finely ensures it cooks through and blends well with the other flavors.
• 3 cloves garlic (≈9 g / 0.3 oz), minced: Garlic is a flavor powerhouse! Minced garlic releases its aromatic compounds, infusing the dish with a savory depth.
• 200 g (7 oz) cherry tomatoes, halved: Cherry tomatoes burst with sweetness and add a vibrant color to the bake. Halving them allows their juices to mingle with the other ingredients.
• 150 g (5 ¼ oz) feta cheese, crumbled: Feta cheese brings a salty, tangy flavor that perfectly complements the chicken and zucchini. Look for a good quality feta, preferably made with sheep’s milk.
• 100 g (3 ½ oz) shredded mozzarella cheese: Mozzarella provides a wonderfully melty and gooey texture, creating a satisfying cheesy layer on top.
• 150 g (5 ¼ oz) plain Greek yogurt (full‑fat): Greek yogurt acts as a creamy binder, keeping the bake moist and adding a subtle tang. Full-fat yogurt provides the best texture and flavor.
• 2 Tbsp (30 ml) olive oil, divided: Olive oil is used for sautéing and adds a healthy fat and rich flavor.
• 1 tsp (5 g) smoked paprika: Smoked paprika adds a delightful smoky flavor that elevates the overall taste profile.
• 1 tsp (5 g) ground cumin: Cumin provides a warm, earthy flavor that complements the paprika and other spices.
• ½ tsp (2½ g) chili flakes (optional): For a touch of heat, add chili flakes. Adjust the amount to your preference.
• Zest of 1 lemon (≈2 g): Lemon zest brightens the flavors and adds a fresh, citrusy note.
• 30 g (¼ cup) almond flour: Almond flour creates a slightly crunchy and nutty topping.
• 2 Tbsp (30 g) grated Parmesan cheese: Parmesan cheese adds a salty, umami flavor and helps create a golden-brown crust.
• Salt and freshly ground black pepper, to taste: Essential seasonings to enhance all the flavors.
• 2 Tbsp (≈6 g) fresh parsley, chopped: Fresh parsley adds a pop of color and a fresh, herbaceous flavor as a garnish.
• 1 lemon, cut into wedges: Lemon wedges are served alongside for an extra burst of freshness.

Substitutions & Variations

Feel free to customize this bake to your liking! Here are a few ideas:

• Chicken: You can substitute chicken breast for the thighs, but be mindful that it may dry out more easily.
• Zucchini: Yellow squash or a mix of summer squashes can be used instead of zucchini.
• Feta: Halloumi cheese is a great substitute for feta, offering a similar salty flavor and firm texture.
• Mozzarella: Provolone or Monterey Jack cheese can be used in place of mozzarella.
• Almond Flour: Breadcrumbs or crushed crackers can be used for the topping.

Step-by-Step Instructions for the Perfect High Protein Chicken Zucchini Bake

1. Preheat and Prepare: Begin by preheating your oven to 190°C (375°F). This ensures even cooking. While the oven heats, lightly oil a 23 x 33 cm (9 x 13-inch) glass baking dish. Using a glass dish allows you to easily monitor the browning of the bake.
2. Brown the Chicken: Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the cubed chicken thighs and season generously with salt, pepper, smoked paprika, cumin, and chili flakes (if using). Sauté for 4-5 minutes, stirring occasionally, until the chicken is lightly browned on all sides. The goal here isn’t to cook the chicken through, just to develop some color and flavor. Transfer the browned chicken to a plate and set aside.
3. Sauté the Vegetables: Add the remaining 1 tablespoon of olive oil to the same skillet. Add the diced red onion and sauté for 3-4 minutes, until it becomes translucent and softened. Next, add the minced garlic and cook for just 30 seconds, until fragrant. Be careful not to burn the garlic! Add the zucchini slices, season with salt and pepper, and cook for another 3 minutes, until they are just slightly softened. Removing the vegetables from the heat at this stage prevents them from becoming mushy during baking.
4. Prepare the Yogurt-Feta Sauce: In a medium bowl, whisk together the plain Greek yogurt, lemon zest, and half of the crumbled feta cheese. Season lightly with salt. The Greek yogurt provides a creamy base and adds extra protein, while the feta adds a salty, tangy flavor.
5. Layer the Bake: Now it’s time to assemble! Spread half of the sautéed zucchini mixture evenly across the bottom of the prepared baking dish. Sprinkle half of the browned chicken cubes over the zucchini. Drizzle half of the yogurt-feta sauce over the chicken. Repeat these layers with the remaining zucchini, chicken, and sauce, ensuring the top layer is a smooth coating of the yogurt-feta mixture.
6. Create the Crunchy Topping: Sprinkle the almond flour, grated Parmesan cheese, shredded mozzarella cheese, and the remaining crumbled feta evenly over the top of the bake. This combination creates a beautiful golden-brown, crunchy crust that adds texture and flavor.
7. Bake to Perfection: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the crust is deep golden brown and bubbly. To ensure the chicken is cooked through, insert a meat thermometer into the thickest part of a chicken piece; it should register 75°C (165°F). If the surface starts to brown too quickly, loosely cover the dish with aluminum foil for the last 5 minutes of baking.
8. Rest and Garnish: Remove the bake from the oven and let it rest for 5 minutes before serving. This allows the juices to redistribute, resulting in a more flavorful and cohesive dish. Garnish with chopped fresh parsley and serve with lemon wedges.

Why Chicken Thighs are Ideal for Baking

While chicken breast is often favored for its lean protein content, chicken thighs are a superior choice for baking. They contain more fat, which keeps the meat incredibly moist and tender during the longer cooking time. The higher fat content also contributes to a richer flavor. Because this bake includes a longer cooking time, the thighs won’t dry out like breasts can.

Adjusting the Spice Level

The chili flakes in this recipe add a subtle warmth. If you prefer a milder dish, simply omit them. For those who enjoy more heat, you can increase the amount of chili flakes or add a pinch of cayenne pepper. Remember to taste as you go and adjust the seasoning to your preference!

Substitutions for Dietary Needs

This recipe is quite versatile! For a gluten-free version, ensure your almond flour and Parmesan cheese are certified gluten-free. To make it dairy-free, substitute the Greek yogurt with a plant-based yogurt alternative (coconut or cashew yogurt work well) and omit the feta and mozzarella cheeses. You could also use a dairy-free mozzarella alternative.

Make-Ahead Tips for a Weeknight Meal

To save time on busy weeknights, you can assemble the bake ahead of time. Prepare the chicken and zucchini as directed, and layer everything in the baking dish. Cover tightly with plastic wrap and refrigerate for up to 24 hours. When ready to bake, add the topping and bake as directed, potentially adding 5-10 minutes to the cooking time.

Frequently Asked Questions

Can I use other vegetables?
