High-Protein Spinach Artichoke Chicken Casserole
This high-protein spinach artichoke chicken casserole delivers all the rich, creamy comfort of your favorite party dip packed into a wholesome, muscle-building weeknight dinner.
- Blended Cottage Cheese: Creates a thick, velvety sauce that mimics heavy cream without the excess fat.
- Double Squeezed Spinach: Removing the water prevents the casserole from separating during baking.
- High-Protein Ratio: Packed with lean chicken breast and Greek yogurt to keep you full for hours.
I once cried over a watery spinach dip.
My husband tried to eat it anyway, but the yellow grease slick pooling on top of the baking dish was an absolute dealbreaker.
The issue, as I later realized after a deep dive into dairy emulsion physics, was that standard cream cheese and sour cream bases simply cannot handle the high heat of a baking oven without breaking. When you add the moisture-heavy cellular structure of frozen spinach and canned artichokes to the mix, you are essentially inviting a watery disaster into your casserole.
To fix this, I swapped the heavy cream bases for a high-protein combination of cottage cheese and Greek yogurt.
Blending the cottage cheese until silky smooth creates a stable protein matrix that locks in moisture. This gives you that luxurious, velvety mouthfeel without a single gram of heavy cream, making it a stellar addition to your rotation of High Protein Recipes That Burn Fat.
It is absolutely perfect.

High-Protein Spinach Artichoke Chicken Casserole
Ingredients
- 2 cups cooked chicken breast, shredded
- 10 oz frozen chopped spinach, thawed and squeezed completely dry
- 14 oz canned artichoke hearts, drained and chopped
- 1.5 cups cottage cheese (preferably Good Culture brand)
- 0.5 cup plain non-fat Greek yogurt
- 1.5 tsp Diamond Crystal kosher salt
- 1 tsp garlic powder
- 0.5 tsp freshly cracked black pepper
- 1 cup shredded low-moisture mozzarella cheese, divided
- 0.25 cup grated Parmesan cheese
Directions
- Preheat your oven to 375°F (190°C) and lightly grease an 8x11-inch or 9x9-inch baking dish with non-stick spray.
- Add the cottage cheese to a high-speed blender or food processor and blend for 45 to 60 seconds until completely smooth and velvety.
- In a large mixing bowl, combine the blended cottage cheese, Greek yogurt, garlic powder, Diamond Crystal kosher salt, and black pepper.
- Fold in the shredded chicken, thoroughly squeezed spinach, chopped artichoke hearts, and half of the shredded mozzarella cheese.
- Spread the mixture evenly into your prepared baking dish, smoothing the top with a spatula.
- Sprinkle the remaining mozzarella and grated Parmesan cheese evenly over the top.
- Bake for 25 to 30 minutes until the casserole is bubbling at the edges and the cheese on top is melted and golden brown.
Notes
- Salt Conversion: We highly recommend using Diamond Crystal Kosher Salt. If you are using fine sea salt or table salt, reduce the amount by half (use 3/4 teaspoon instead of 1.5 teaspoons) to avoid over-salting.
- Spinach Science: Squeezing the spinach completely dry is non-negotiable. Spinach contains water-soluble cellular walls that collapse under heat; if you do not wring it out in a clean kitchen towel until your forearms ache, that excess water will release during baking and break your dairy emulsion.
- Broiler Warning: Keep a close eye on the broiler if you decide to brown the cheese at the end. The high protein content in the Greek yogurt and mozzarella means it can transition from beautifully caramelized to scorched in under 45 seconds.
- Storage Behavior: Upon cooling, the cottage cheese protein matrix will firm up significantly. When reheating, add a splash of chicken broth or water to loosen the sauce back to its original velvety state.
- Brand Recommendation: I tested this with three different brands of cottage cheese, and the generic store brand failed every single test because it was too watery; stick to Good Culture for the best thick texture.
Serving Suggestions
Serve this bubbling casserole hot out of the oven. It pairs beautifully with light, crisp sides to balance the rich, cheesy texture of the dish.
- Pair it with a side of Garlic Parmesan Broccoli for an extra dose of green goodness.
- Serve over a bed of warm cauliflower rice to keep the meal low-carb and high-fiber.
- Scoop it up with toasted sourdough bread or low-carb crackers for a dip-style dinner.
- Accompany with a simple, bright arugula salad dressed with fresh lemon juice and olive oil.
Storage and Reheating
Store any leftover casserole in an airtight container in the refrigerator for up to four days. The flavors actually meld together beautifully overnight, making day-two lunch something you will genuinely look forward to.
I do not recommend freezing this dish because the freezing process expands the water molecules in both the Greek yogurt and the artichokes. When thawed, these ice crystals melt and rupture the delicate protein emulsion, leaving you with a grainy, separated mess that no amount of stirring can save.
Reheating is incredibly simple.
Just pop a portion into the microwave covered with a damp paper towel to trap the steam.
Alternatively, place it back in a 350°F oven for about 15 minutes until the cheese is bubbly again. Add a tiny splash of water or milk before heating to restore that luscious, velvety texture.
Ingredient Substitutes
If you need to adapt this recipe based on what is currently in your pantry, here are the easiest swaps:
- Cottage Cheese: If you absolutely cannot stand cottage cheese, you can substitute it with ricotta cheese, though the protein content will be slightly lower.
- Greek Yogurt: Sour cream can be used in place of Greek yogurt, but it will increase the fat content and reduce the protein.
- Chicken Breast: Leftover rotisserie chicken or shredded turkey works beautifully as a time-saving shortcut.
- Spinach: Kale can be used instead of spinach, but make sure to sauté and soften it before adding it to the mixture.
This casserole has officially saved my weeknight sanity more times than I can count, and I hope it brings that same cozy, effortless joy to your kitchen table. Let me know if you make it, and especially if you manage to resist eating the bubbly cheese right off the spatula!
