Spinach Artichoke Chicken Casserole

The first time I made this casserole, my apartment building smelled like an Italian restaurant and my neighbor actually knocked on my door to ask what I was cooking. That's when I knew this recipe was special. It's become my go-to for meal prep Sundays because it makes the whole week feel like a treat.

Last winter my sister was recovering from surgery and I brought her a pan of this casserole. She texted me three days later saying it was the only thing that actually tasted good and made her feel cared for. Now she asks for it every time she's having a rough week.

Ingredients

• 900 g boneless skinless chicken breasts: Dicing it yourself means you control the size and texture, plus it stays more tender than precut chicken
• 250 g low-fat cottage cheese: This unsung hero adds creaminess and protein while keeping the casserole lighter than traditional versions
• 120 g shredded part-skim mozzarella cheese: Use the shredded cheese from the block rather than pre-shredded bags for better melting
• 60 g grated Parmesan cheese: The salty umami punch that ties everything together
• 200 g frozen chopped spinach: Thaw it completely and squeeze out every drop of water or your casserole will be soupy
• 400 g canned artichoke hearts: These add a tangy brightness that cuts through all the rich dairy
• 1 medium yellow onion: Finely diced so it melts into the background rather than having obvious onion pieces
• 2 cloves garlic: Fresh is non-negotiable here for that aromatic backbone
• 120 g light cream cheese: Softened to room temperature so it blends seamlessly into the sauce
• 120 ml plain Greek yogurt: The secret ingredient that adds tang and protein without anyone guessing it's there
• 1 tsp dried Italian herbs: Or use a mix of dried oregano and basil
• 1/2 tsp ground black pepper: Freshly cracked makes a noticeable difference
• 1/2 tsp salt: Adjust this based on how salty your cheeses are
• 1/4 tsp crushed red pepper flakes: Even if you think you don't like heat, this tiny amount adds depth without spice
• 30 g gluten-free panko breadcrumbs: Regular panko works fine unless you need this to be gluten-free
• 20 g grated Parmesan cheese: Extra for the top because you can never have too much Parmesan crust
• Olive oil spray: For getting that perfect golden crunch on the topping

Instructions

Get your oven ready:

Preheat to 200°C and grease a 23x33 cm casserole dish so nothing sticks later.

Build your flavor base:

Sauté the diced onion in a splash of olive oil for 3 to 4 minutes until it softens and turns translucent, then add garlic for just 30 seconds until fragrant.

Cook the chicken:

Add diced chicken to the skillet and cook for 5 to 6 minutes until just cooked through, remembering it will finish in the oven.

Make the creamy sauce:

In a large bowl, combine cream cheese, Greek yogurt, cottage cheese, mozzarella, 60 g Parmesan, Italian herbs, salt, pepper, and red pepper flakes until completely smooth.

Bring it all together:

Fold in the cooked chicken mixture, thawed spinach, and chopped artichoke hearts until everything is evenly distributed.

Assemble the casserole:

Spread the mixture evenly into your prepared dish and press down gently to remove any air pockets.

Add the golden topping:

Mix panko breadcrumbs with the remaining 20 g Parmesan and sprinkle evenly over the casserole, then give it a light mist of olive oil spray.

Bake until bubbly:

Bake for 30 to 35 minutes until you see golden brown edges and hear that satisfying sizzle.

Let it rest:

Wait 5 to 10 minutes before serving so the casserole sets and makes serving much easier.

Save

This recipe transformed how I think about high-protein meals. I used to associate protein-focused cooking with dry, boring food, but this casserole proved that comfort and nutrition can coexist beautifully.

Make It Your Own

Sometimes I add sun-dried tomatoes when I want extra sweetness, or swap in rotisserie chicken on busy weeknights. The recipe is forgiving and welcomes substitutions.

Pairing Ideas

A crisp green salad with vinaigrette cuts through the richness perfectly. I also love serving it with roasted broccoli or steamed green beans for color.

Storage and Reheating

This casserole actually tastes better the next day as the flavors meld together. Store it in the refrigerator for up to five days, or freeze individual portions for those nights when cooking feels impossible.

• Reheat covered with foil at 180°C until warmed through, about 20 minutes
• For a crispy top, remove the foil for the last 5 minutes of reheating
• Microwave individual portions in 90 second intervals, stirring between each

There's something deeply satisfying about serving a casserole that looks impressive but came together so easily. This recipe has earned its permanent spot in my regular rotation.

Recipe FAQs

→ Can I make this ahead of time?

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

→ Can I freeze this casserole?

Freeze unbaked for up to 3 months. Thaw overnight in the refrigerator before baking. You can also freeze leftovers in individual portions for easy meal prep.

→ What can I substitute for cottage cheese?

Ricotta cheese works well as a substitute. For a dairy-free version, use cashew cream or a plant-based ricotta alternative.

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

The internal temperature should reach 74°C (165°F). Since the chicken is partially cooked on the stovetop first and then baked, 30-35 minutes in the oven ensures doneness.

→ Can I use fresh spinach instead of frozen?

Yes, use about 300 g fresh spinach. Sauté until wilted, then squeeze out excess moisture before adding to the mixture to prevent a watery casserole.

→ What sides pair well with this dish?

A crisp green salad with vinaigrette, roasted broccoli, steamed asparagus, or cauliflower rice all complement the rich flavors while keeping the meal light.
