How to Make High-Protein Spinach and Artichoke Chicken Casserole Recipe
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). This step ensures the casserole will bake evenly and the cheese topping will turn that perfect golden brown.
Step 2: Prepare the Mixture
In a large bowl, combine your shredded chicken, chopped artichoke hearts, thawed and drained spinach, Greek yogurt, cottage cheese, minced garlic, onion powder, salt, and pepper. Give everything a thorough mix so every bite is bursting with flavor — this is the heart of your High-Protein Spinach and Artichoke Chicken Casserole Recipe.
Step 3: Assemble the Casserole
Grease a 9×13-inch baking dish lightly to prevent sticking. Evenly spread the chicken mixture into the dish, smoothing it out so it bakes uniformly. Then, top with shredded mozzarella and sprinkle grated Parmesan cheese over the surface.
Step 4: Bake to Perfection
Place your dish in the preheated oven and bake for 25–30 minutes. Keep an eye out for bubbling around the edges and a glorious golden crust on top. This indicates everything is cooked through and the cheese has melted into a creamy, delightful blanket.
Step 5: Rest and Serve
After baking, let the casserole cool for a few minutes — this helps it set and makes serving easier. You can garnish with some fresh parsley for a pop of color and freshness, then dive into the deliciousness that is your High-Protein Spinach and Artichoke Chicken Casserole Recipe.
How to Serve High-Protein Spinach and Artichoke Chicken Casserole Recipe

Garnishes
A sprinkle of freshly chopped parsley or a few red pepper flakes adds beautiful contrast and a hint of freshness. For an extra touch, a dollop of sour cream or a squeeze of lemon can brighten the rich, creamy flavors.
Side Dishes
Since this casserole is packed with protein and veggies, light sides work best. Try a crisp green salad with a tangy vinaigrette or some roasted root vegetables to complement the richness without overwhelming it.
Creative Ways to Present
Serve this casserole straight from the baking dish for cozy family dinners, or spoon portions into small ramekins for individual servings at parties. It also works beautifully as a layered dish in a buffet, staying warm under a chafing dish for guests to enjoy.
Make Ahead and Storage
Storing Leftovers
Store any leftovers in an airtight container in the refrigerator for up to 4 days. The flavors will meld even more over time, making your next meal just as tasty as the first.
Freezing
This casserole freezes wonderfully. Portion it into freezer-safe containers and freeze for up to 3 months. When you’re ready, thaw overnight in the refrigerator for best results.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through and bubbly again, about 15–20 minutes. Microwaving works too but may make the cheese a bit rubbery, so keep it brief and cover to retain moisture.
FAQs
Can I use fresh spinach instead of frozen?
Absolutely! Just sauté about 10 ounces of fresh spinach until wilted and squeeze out excess moisture before adding it to the casserole. This will maintain the right texture and flavor balance.
Is it possible to make this recipe dairy-free?
Yes, swaps like dairy-free yogurt, cottage cheese alternatives, and vegan cheeses can work. Keep in mind the texture and flavor will vary slightly, but the casserole will still be delicious.
Can I use a different type of cheese?
Definitely! Cheeses like cheddar, Monterey Jack, or provolone can be used for different flavor profiles. Just pick varieties that melt well to keep that luscious cheesy topping.
How long does it take to cook the chicken?
For this recipe, cooking and shredding your chicken can be done in advance. Poaching chicken breasts takes about 15–20 minutes until cooked through, but you can also use rotisserie chicken for convenience.
Is this recipe suitable for meal prep?
Yes, it’s an ideal meal prep dish. Make it ahead, portion it out, and store in the fridge or freezer. It reheats beautifully, providing a nutritious, high-protein dinner all week long.
