High Protein Spinach Artichoke Chicken Casserole

The aroma of bubbling cheese and spinach filled my tiny apartment kitchen during that first brutal winter after college. I was trying to eat something that felt like comfort food but wouldnt derail my fitness goals. This casserole became the answer, and now it is the one dish my friends actually request when they come over for dinner.

My sister was skeptical when I told her what was actually in this. She took one bite and literally stopped talking mid sentence. That was the moment I knew this recipe was a keeper.

Ingredients

• 900 g boneless skinless chicken breasts: Dicing these into bite sized pieces helps them cook evenly and stay tender throughout the baking process
• 250 g low fat cottage cheese: This creates an incredibly creamy base while keeping the protein content sky high
• 120 g shredded part skim mozzarella: Low moisture mozzarella melts beautifully without making the dish greasy
• 60 g grated Parmesan: Adds that savory umami depth that makes you keep going back for another bite
• 200 g frozen chopped spinach: Thawing and squeezing out every drop of liquid prevents a watery casserole
• 400 g canned artichoke hearts: Drain these well and chop them into pieces that match the chicken size
• 1 medium yellow onion: Finely dicing ensures the onion cooks down completely before mixing everything together
• 2 cloves garlic: Fresh garlic beats powdered every single time in this recipe
• 120 g light cream cheese: Let this come to room temperature so it blends smoothly into the sauce
• 120 ml plain Greek yogurt: Use full fat or 2 percent for the best texture and flavor
• 1 tsp dried Italian herbs: A blend of oregano, basil, and thyme works perfectly here
• 1/2 tsp ground black pepper: Freshly cracked pepper makes a noticeable difference
• 1/2 tsp salt: The Parmesan provides plenty of saltiness, so do not overdo it
• 1/4 tsp crushed red pepper flakes: Optional, but that little hint of heat makes everything pop
• 30 g panko breadcrumbs: Gluten free panko creates the perfect crispy topping without getting soggy
• 20 g grated Parmesan: Mixed into the breadcrumbs for an extra golden, cheesy crust
• Olive oil spray: A light mist helps the topping turn beautifully golden brown

Instructions

Get your oven ready:

Preheat to 200°C (400°F) and grease a 23x33 cm casserole dish with cooking spray or olive oil

Sauté the aromatics:

Cook the diced onion in a splash of olive oil for 3 to 4 minutes until softened, then add garlic for 30 seconds until fragrant

Cook the chicken:

Add diced chicken and cook 5 to 6 minutes until just cooked through, removing from heat before it dries out

Make the sauce:

Whisk together cream cheese, Greek yogurt, cottage cheese, mozzarella, 60 g Parmesan, Italian herbs, salt, pepper, and red pepper flakes until completely smooth

Combine everything:

Fold in the cooked chicken, thawed spinach, and chopped artichokes until evenly distributed

Assemble the casserole:

Spread the mixture evenly into your prepared baking dish

Prepare the topping:

Mix panko breadcrumbs with 20 g Parmesan and sprinkle evenly over the casserole, then mist lightly with olive oil spray

Bake to perfection:

Bake for 30 to 35 minutes until bubbling around the edges and golden brown on top

Let it rest:

Wait 5 to 10 minutes before serving so the casserole sets up and slices cleanly

This dish has gotten me through countless meal prep Sundays and late night dinner cravings. Something about pulling that bubbling, golden dish out of the oven just feels like home.

Make It Your Own

Sometimes I add sun dried tomatoes for extra brightness or swap in rotisserie chicken when I am short on time. The base recipe is forgiving enough to handle whatever tweaks you dream up.

Perfect Pairings

A crisp green salad with lemon vinaigrette cuts through the richness perfectly. Roasted broccoli or steamed green beans also work beautifully on the side.

Storage And Reheating

This keeps beautifully in the refrigerator for up to four days and actually tastes even better the next night. I portion it into glass containers right after it cools for easy grab and go lunches throughout the week.

• Reheat individual portions in the microwave for 2 to 3 minutes, covered
• Cover the whole dish with foil and reheat at 175°C (350°F) for about 20 minutes
• Let leftovers come to room temperature before freezing for best texture

Hope this becomes a staple in your kitchen like it has in mine. There is nothing quite like watching people enjoy something that is both good for them and incredibly satisfying.

Recipe Questions & Answers

→ Can I make this casserole ahead of time?

Yes, assemble the entire casserole up to 24 hours in advance and refrigerate unbaked. Add 5-10 minutes to the baking time if cooking from cold.

→ How long do leftovers keep in the refrigerator?

Store leftovers in an airtight container for up to 4 days. Reheat individual portions in the microwave or cover the dish with foil and warm at 175°C (350°F) until heated through.

→ Can I freeze this casserole?

Freeze before baking by wrapping tightly in plastic and foil for up to 3 months. Thaw overnight in the refrigerator before baking, or add 15-20 minutes to the bake time if cooking from frozen.

→ What can I substitute for the cottage cheese?

Ricotta cheese works well as a substitute, or use additional cream cheese blended with the Greek yogurt. For a dairy-free version, try plain almond-based yogurt and vegan cream cheese.

→ Do I need to thaw the spinach completely?

Yes, thawing and squeezing out excess moisture is crucial. Wet spinach will make the casserole soupy rather than creamy. Thaw in the refrigerator overnight or use the defrost setting on your microwave.

→ Can I use fresh spinach instead of frozen?

Certainly. Cook about 500g of fresh spinach in a large pan until wilted, then drain thoroughly and chop before adding to the mixture.
