High Protein Spinach Artichoke Chicken

The rain was hammering against the kitchen window the Tuesday I threw this casserole together with whatever was left in the fridge before a grocery run. My neighbor had just dropped off a bag of fresh spinach from her garden, and I had a massive pack of chicken breasts that needed using. What came out of the oven forty minutes later was so absurdly good that my husband stood at the counter eating it straight from the dish with a fork.

I brought this to a potluck last winter and three people pulled me aside to ask for the recipe before dessert was even served. One friend texted me the next morning saying she had already bought all the ingredients to make it herself.

Ingredients

• 900 g boneless skinless chicken breast: Cook it however you like, but poaching keeps it extra moist and easy to shred with two forks.
• 225 g fresh spinach: Fresh wilts down beautifully, but frozen works fine if you squeeze every last drop of water out first.
• 400 g canned artichoke hearts: Drain them well and chop roughly so no one gets a giant artichoke chunk in one bite.
• 1 medium yellow onion: Finely diced so it melts into the background sweetness of the dish.
• 2 cloves garlic: Fresh only please, the jarred stuff tastes flat here.
• 200 g Greek yogurt: Plain and full fat or low fat both work, just skip the flavored ones obviously.
• 120 ml light cream cheese: Let it soften on the counter first or you will be arm wrestling lumps.
• 120 ml cottage cheese: This is the secret weapon that makes everything creamy and adds even more protein.
• 100 g part skim mozzarella: Save half for the top because that golden cheese cap is everything.
• 30 g grated Parmesan: It brings a salty depth that ties the whole thing together.
• 1 tbsp olive oil: Just enough to get the onions going.
• 1 tsp dried Italian herbs: A simple blend does heavy lifting here.
• Salt, pepper, and a pinch of cayenne: The cayenne is optional but it wakes up all the other flavors.
• 40 g gluten free breadcrumbs: Optional topping that gives a satisfying crunch.

Instructions

Get the oven ready:

Preheat to 190 degrees Celsius and grease your casserole dish so nothing sticks later.

Build the flavor base:

Heat olive oil in a large skillet over medium heat and cook the onion until it turns translucent and sweet, about 3 to 4 minutes, then stir in the garlic for one more minute until your kitchen smells incredible.

Wilt the spinach:

Add the spinach to the pan and toss until wilted if fresh or warmed through if frozen.

Combine the hearty stuff:

Transfer the veggies to a big bowl, add the shredded chicken and chopped artichokes, and give it a gentle toss.

Make the creamy sauce:

In a separate bowl, stir together the Greek yogurt, cream cheese, cottage cheese, half the mozzarella, Parmesan, Italian herbs, salt, pepper, and cayenne until smooth and creamy.

Bring it all together:

Fold the cheese mixture into the chicken and vegetables, making sure everything gets coated in that luscious sauce.

Assemble and top:

Spoon the mixture into your prepared dish, scatter the remaining mozzarella on top, and sprinkle with breadcrumbs if you are using them.

Bake until golden:

Pop it in the oven for 25 to 30 minutes until the edges are bubbling and the top has that gorgeous golden color you see in magazine photos.

Let it rest:

Give it 5 to 10 minutes before serving so it holds together when you scoop it.

This dish became our Sunday night standby because it reheats perfectly for lunches all week and somehow tastes even better on day two.

What To Serve Alongside

A simple green salad with lemon vinaigrette cuts right through the richness, and a scoop of brown rice on the side makes it feel like a complete feast without any extra effort.

Storage and Leftovers

Cover the dish tightly and refrigerate for up to four days. You can also portion it into individual containers for grab and go lunches that will actually make you excited to open the fridge.

Making It Your Own

This recipe is forgiving and loves improvisation, so feel free to riff based on what you have on hand.

• Chopped sun dried tomatoes add a tangy sweetness that pairs beautifully with the creamy base.
• Roasted red peppers stirred in give smoky depth and a pop of color.
• Swap the Greek yogurt for sour cream if you want a richer, more indulgent result.

Recipe FAQs

→ Can I use rotisserie chicken instead of cooking fresh chicken?

Absolutely. A store-bought rotisserie chicken works perfectly and will actually save you significant prep time. Simply shred the meat and proceed with the recipe as written.

→ What can I substitute for cottage cheese if I don't care for the texture?

You can replace cottage cheese with an equal amount of ricotta cheese for a smoother texture. Alternatively, increase the cream cheese to 1 cup and add extra Greek yogurt to maintain the creamy consistency.

→ Is this casserole freezer-friendly?

Yes, this dish freezes exceptionally well. Assemble everything in your baking dish, wrap tightly with plastic and foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed.

→ Can I make this without breadcrumbs for a keto version?

Certainly. Simply omit the breadcrumb topping entirely. The casserole will still develop a beautiful golden crust from the melted mozzarella and Parmesan cheese on top.

→ What sides pair well with this casserole?

A crisp green salad with vinaigrette helps cut through the richness. Roasted vegetables like broccoli or cauliflower work nicely, as do whole grains such as quinoa or brown rice for a more substantial meal.

→ How do I know when the casserole is fully cooked?

The dish is ready when the cheese is bubbling and golden brown on top, typically after 25-30 minutes at 190°C (375°F). The internal temperature should reach 165°F (74°C) when tested with a food thermometer.
