How to Make High Protein Spinach And Artichoke Chicken Casserole Recipe
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures it’ll be ready once your casserole mixture is prepared, allowing for even cooking and that perfect golden top you’re aiming for.
Step 2: Sauté Garlic and Spinach
Heat a small amount of olive oil in a skillet over medium heat. Add the minced garlic and sauté just until fragrant to awaken those savory notes. Immediately stir in the fresh spinach, cooking until it’s wilted but still vibrant green. This step brings out the spinach’s natural tenderness and melds it with garlic’s aromatic goodness.
Step 3: Combine All Ingredients
In a large mixing bowl, bring together the shredded chicken, sautéed spinach and garlic, chopped artichoke hearts, Greek yogurt, cream cheese, mozzarella, Parmesan, salt, and pepper. Mix everything thoroughly so that all the flavors are evenly distributed and every bite is packed with delightful layers.
Step 4: Transfer to Baking Dish
Grab a greased 9×13 inch baking dish and spread the mixture evenly across the bottom. This ensures consistent cooking and allows the cheese to melt evenly over the top for that irresistible crust.
Step 5: Bake Until Golden
Place the casserole in your preheated oven and bake for 25 to 30 minutes. Keep an eye out for that golden brown and bubbly top — a surefire sign your High Protein Spinach And Artichoke Chicken Casserole Recipe is ready to make its grand entrance at the table.
Step 6: Let It Rest
Allow the casserole to cool for about 5 to 10 minutes after baking. This resting time lets everything settle and makes serving much easier, while giving the flavors time to harmonize perfectly.

Garnishes
For a fresh finish, sprinkle some chopped fresh parsley or chives on top just before serving. A light dusting of extra Parmesan can also add a lovely, savory touch that complements the casserole’s creamy richness.
Side Dishes
This casserole pairs wonderfully with simple, crisp sides like a mixed green salad with a lemon vinaigrette or steamed seasonal veggies. Light sides help balance the richness and keep the meal feeling fresh and satisfying.
Creative Ways to Present
For an elegant yet easy presentation, serve individual portions in ramekins or small baking dishes. This not only makes for beautiful plating but is perfect for portion control and serving guests with flair.
Make Ahead and Storage
Storing Leftovers
Place leftover casserole in an airtight container and refrigerate for up to 3 days. The flavors continue to meld beautifully, making your next meal just as delicious as the first.
Freezing
This High Protein Spinach And Artichoke Chicken Casserole Recipe freezes well. After baking, cool completely, then wrap tightly with plastic wrap and foil or use freezer-safe containers. It can be frozen for up to 2 months without losing flavor or texture.

FAQs
Can I use frozen spinach instead of fresh?
Absolutely, but make sure to thaw and squeeze out as much excess moisture as possible before sautéing. This helps prevent your casserole from becoming watery and keeps the flavors concentrated.
Is it possible to use shredded rotisserie chicken?
Yes! Using rotisserie chicken is a fantastic shortcut that adds extra flavor and saves time. Just shred it and proceed with the recipe as described.
Can I substitute the Greek yogurt for sour cream?
You can, though Greek yogurt adds extra protein and a tangy brightness that balances the richness. Sour cream will give a creamier texture but with slightly less protein.
What type of artichoke hearts works best?
Canned artichoke hearts packed in water and well-drained are perfect here. They offer consistent taste and tenderness ideal for casseroles like this one.
Is this recipe suitable for meal prepping?
Definitely! It holds up well for several days in the fridge and freezes beautifully, making it a reliable, nutritious option for busy weeks ahead.
