Ingredients You Need For This Wheat Free Meal

- 1.5 pounds boneless skinless chicken breast, diced into bite-sized pieces
- 2 medium zucchini, chopped into half-moons
- 1 tablespoon olive oil
- 1 teaspoon garlic powder

How To Make This Chicken High Protein Meal
Getting this dinner into the oven is straightforward. It is one of those chicken high protein meals that practically cooks itself once you finish chopping the fresh ingredients.
- Preheat your oven to 400 degrees Fahrenheit and lightly grease a 9×13 inch glass or ceramic baking dish with olive oil.
- Place the diced chicken breast pieces and the chopped zucchini half-moons into a large mixing bowl.
- Drizzle the extra virgin olive oil evenly over the raw chicken and vegetables.
- Sprinkle the garlic powder, smoked paprika, salt, and black pepper over everything. Toss the mixture well with a large spoon until every piece is fully coated in spices.
- Transfer the entire mixture to your prepared baking dish, using your spoon to spread it out into a single, even layer.
- Bake uncovered on the middle oven rack for 20 minutes, until the chicken is mostly cooked through and no longer pink in the center.
- Remove the dish carefully from the oven, and sprinkle the shredded mozzarella and grated parmesan cheeses evenly over the hot chicken and zucchini.
- Return the dish to the oven for another 10 minutes until the cheese is completely melted and bubbly.
Expert Tips For Perfect Baked Chicken Dishes
One common issue cooks face with baked chicken dishes is excess moisture pooling at the bottom. Zucchini naturally holds a lot of water, which can make casseroles watery if you are not careful. To absolutely prevent this, lightly salt your chopped zucchini and let it sit in a colander for ten minutes. Pat them dry with a clean paper towel before mixing them with the raw chicken. Also, make sure you cut your chicken breasts into uniform pieces so everything cooks at the same rate. If you notice the cheese topping browning too quickly, loosely tent aluminum foil over the baking dish during the last few minutes.
Ingredient Substitutions And Variations
This savory bake is very forgiving and easy to customize. If you prefer the richer flavor of dark meat, simply swap the chicken breasts for boneless, skinless chicken thighs. Thighs stay incredibly juicy in the hot oven. Want a bit of a crunch on top? Even though this is not one of those heavy recipes with breaded chicken, you can sprinkle crushed gluten-free crackers on top just before adding the cheese layer. For extra nutrients, toss in a handful of cherry tomatoes or diced bell peppers. Just remember that adding more fresh vegetables might add slightly more moisture to the pan.
Storage And Serving Suggestions
Leftovers of this High Protein Chicken Zucchini Bake store wonderfully for the days ahead. Keep remaining cooled portions in an airtight container in the refrigerator for up to four days. Reheat a portion in the microwave for a minute or two, or pop it back in a warm oven until it is heated through completely.
Serve this dish exactly as it is for a satisfying meal, or pair it with cooked quinoa or brown rice to soak up the seasoned juices. It makes an excellent high protein dinner for two on a weeknight, leaving you with leftovers to enjoy for a healthy lunch the very next day.
FAQ
1. Can I freeze this bake?
Yes, you can freeze it. However, keep in mind that zucchini gets a bit mushy when frozen and thawed. It is best enjoyed fresh or from the fridge.
2. Do I need to peel the zucchini?
No, peeling is not necessary. The skin adds great color, nice texture, and extra nutrients to the finished dish.
3. Can I use rotisserie chicken instead?
Since rotisserie chicken is already cooked, you would need to adjust the cooking time. Just bake the zucchini until tender, then stir in the cooked chicken and top with cheese to melt.
4. Is this recipe spicy?
Not at all. The smoked paprika adds a nice depth of flavor without any heat. If you want a spicy kick, add half a teaspoon of red pepper flakes to the spice mix.
5. What other cheese works well?
Cheddar, gouda, or provolone are excellent alternatives if you do not have mozzarella on hand.
6. How do I know when the chicken is fully cooked?
The safest way is to use a digital meat thermometer. The internal temperature of the thickest chicken pieces should reach 165 degrees Fahrenheit.
