This Lazy Chicken Parmesan Quinoa Casserole is a cozy meal that combines tender chicken, hearty quinoa, and delicious marinara sauce, all topped with gooey cheese. It’s a savory delight!
What I love most is how easy it is to make—just mix everything in one dish and bake. Perfect for when you want a tasty dinner without all the fuss. Who doesn’t appreciate a little lazy cooking? 😄
Key Ingredients & Substitutions
Quinoa: This grain is the star of the dish—it’s gluten-free and a great protein source. If you don’t have quinoa, try cooked brown rice or couscous as alternatives. Both are easy to find and provide a nice texture.
Chicken: Ground chicken is easy to work with, but boneless chicken breast or thighs diced into small pieces works well too. For a lighter option, consider using ground turkey.
Marinara Sauce: Store-bought marinara is super convenient. However, if you’re feeling adventurous, homemade sauce with crushed tomatoes, garlic, and herbs tastes amazing. You can also use pesto for a fresh twist!
Cheeses: Mozzarella is perfect for that stretchy, cheesy layer. I often mix in some cheddar for an extra flavor kick. In case you’re dairy-free, there are excellent plant-based cheese alternatives available these days.
How Can I Ensure the Chicken is Cooked Perfectly?
Cooking the chicken thoroughly while keeping it juicy is key for this casserole. Make sure to break up any ground chicken as you mix it in. If using diced chicken, cut it into small, even pieces to promote even cooking.
- Always check the internal temperature of the chicken. It should reach 165°F (75°C) to be safe to eat.
- Covering the dish with foil during the first part of baking helps keep moisture in, ensuring tender chicken.
- Letting it rest for a few minutes after baking allows the juices to redistribute, keeping everything flavorful.

Ingredients You’ll Need:
For the Casserole:
- 1 cup quinoa, rinsed
- 1¼ cups chicken broth or water
- 1 lb (about 450g) ground chicken or diced chicken breast
- 1½ cups marinara sauce
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese

- 1 garlic clove, minced
- Salt and pepper, to taste

How Much Time Will You Need?
This delicious casserole takes about 10 minutes of prep time and around 50 minutes of cooking time, including baking. In just over an hour, you’ll have a comforting meal that’s perfect for a busy weeknight!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 375°F (190°C). This step is important to get everything just right as you cook your casserole.
2. Prepare the Quinoa:
In a large oven-safe casserole dish, evenly spread out the rinsed quinoa. This will be the base of your dish, soaking up all the flavor from the other ingredients.
3. Add the Chicken:
Scatter the ground chicken or diced pieces over the quinoa. Season with a sprinkle of salt, pepper, and the minced garlic. This adds an amazing depth of flavor to your casserole!
4. Pour the Liquids:
Now, pour the chicken broth (or water) and marinara sauce over the chicken and quinoa mixture, ensuring everything is well combined.
5. Add Italian Seasoning:
Sprinkle the Italian seasoning generously over the top. This will infuse the casserole with delightful herby flavors.
6. Top with Cheese:
Dollop the shredded mozzarella and the grated Parmesan cheese over the casserole. Who doesn’t love a cheesy topping?
7. Bake Covered:
Cover the casserole dish with foil and bake for about 35 minutes. This helps everything to cook through without drying out.
8. Bake Uncovered:
After 35 minutes, carefully remove the foil and bake for an additional 10–15 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and golden brown! Check that the chicken is cooked through; it should reach an internal temperature of 165°F (75°C).
9. Let it Rest:
Once it comes out of the oven, let the casserole sit for about 5 minutes before serving. This helps it set up a bit, making it easier to dish out.
10. Garnish and Enjoy:
Garnish your Lazy Chicken Parmesan Quinoa Casserole with fresh parsley or basil, if desired. Serve it warm and enjoy your comforting meal!
This casserole is a delicious, one-dish meal that combines the protein-packed goodness of chicken and quinoa with the comforting flavors of classic chicken Parmesan, made effortless in one baking dish. Enjoy your cooking adventure!
Can I Use Brown Rice Instead of Quinoa?
Yes, you can substitute brown rice for quinoa! However, keep in mind that brown rice will require more liquid and a longer cooking time—about 1½ cups of broth and approximately 50-60 minutes of baking time. You may want to adjust the liquid accordingly.
How Can I Make This Recipe Vegetarian?
To make this casserole vegetarian, simply swap out the chicken for cooked lentils or your favorite meat substitute, like crumbled tempeh or mushrooms. You can also add more veggies like spinach, bell peppers, or zucchini for extra flavor and nutrition!
Can I Freeze Leftovers?
Absolutely! Allow the casserole to cool completely, then transfer it to an airtight container. It can be stored in the freezer for up to 3 months. To reheat, thaw it overnight in the fridge and bake at 350°F (175°C) until heated through, about 20-30 minutes.
What Sides Pair Well with This Casserole?
This casserole is quite filling on its own, but if you’re looking for sides, a simple green salad or steamed vegetables complement it well. Some garlic bread is also a delicious addition to soak up any leftover marinara sauce!
