High Protein Spinach Artichoke Chicken

My sister texted me at 10pm one Tuesday, asking if I had any healthy comfort food ideas because she'd started a fitness journey but was absolutely craving something creamy and warm. I threw together this casserole on impulse, combining her favorite spinach artichoke dip flavors with lean chicken, and honestly it's become one of those recipes I make at least twice a month now.

The first time I made this for my husband, he took one bite and asked if I'd spent hours stirring a roux on the stove. When I told him it was just cottage cheese, Greek yogurt, and some shredded cheeses blended together, he literally laughed out loud. Now whenever we have friends over for dinner, someone always asks for this recipe before they've even finished their first serving.

Ingredients

• 900 g (2 lbs) boneless skinless chicken breasts diced: Cutting the chicken into bite sized pieces helps it cook faster and ensures every mouthful has tender meat throughout the casserole
• 250 g (1 cup) low fat cottage cheese: This creates an incredibly creamy base while keeping the protein content high and calories surprisingly reasonable
• 120 g (1 cup) shredded part skim mozzarella cheese: Mozzarella melts beautifully and adds that classic stretch factor everyone loves in a baked casserole
• 60 g (1/4 cup) grated Parmesan cheese: The salty nuttiness of Parmesan grounds all the other flavors and prevents the dish from tasting too mild
• 200 g (7 oz) frozen chopped spinach thawed and squeezed dry: Thawing and squeezing out every drop of moisture is absolutely crucial here or your casserole will turn out watery
• 400 g (14 oz) canned artichoke hearts drained and chopped: Artichokes add a subtle tangy brightness that cuts through all the rich cheese and keeps each bite interesting
• 1 medium yellow onion finely diced: Cooking the onion until soft before adding it to the mixture removes any harsh raw onion flavor
• 2 cloves garlic minced: Garlic blooms quickly so add it only in the last 30 seconds of sautéing to prevent any bitterness
• 120 g (1/2 cup) light cream cheese softened: Let this sit at room temperature for an hour and it will blend seamlessly into the sauce without any lumps
• 120 ml (1/2 cup) plain Greek yogurt: Greek yogurt adds a pleasant tang that mimics sour cream but with way more protein and less fat
• 1 tsp dried Italian herbs: Dried oregano basil and thyme work beautifully here but fresh herbs work too if you triple the amount
• 1/2 tsp ground black pepper: Freshly cracked pepper has way more aroma and flavor than pre ground pepper from a shaker
• 1/2 tsp salt: The cheeses and artichokes are already salty so taste the mixture before adding more salt
• 1/4 tsp crushed red pepper flakes optional: Just a tiny pinch adds a gentle warmth that builds slowly without overwhelming the palate
• 30 g (1/3 cup) gluten free panko breadcrumbs: Panko creates an irresistibly crispy golden topping that stays crunchy even underneath the sauce
• 20 g (2 tbsp) grated Parmesan cheese: Mixing Parmesan into the breadcrumbs adds extra umami flavor to the crispy topping layer
• Olive oil spray: A light misting helps the breadcrumbs brown evenly without adding excessive oil or calories

Instructions

Preheat and prep your baking dish:

Heat your oven to 200°C (400°F) and coat a 23x33 cm (9x13-inch) casserole dish with cooking spray so nothing sticks later.

Sauté the aromatics:

Cook the diced onion in a splash of olive oil over medium heat for 3 to 4 minutes until it's soft and translucent then stir in the garlic for just 30 seconds until fragrant.

Cook the chicken pieces:

Add the diced chicken to the skillet and cook for 5 to 6 minutes stirring occasionally until just cooked through then remove from heat.

Make the creamy sauce mixture:

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

Combine everything together:

Fold in the cooked chicken mixture thawed squeezed spinach and chopped artichokes until everything is evenly coated in the cheese sauce.

Transfer to the baking dish:

Spread the mixture evenly into your prepared casserole dish using a spatula to create a smooth flat surface.

Prepare the crispy topping:

Mix the panko breadcrumbs with 20 g Parmesan in a small bowl then sprinkle evenly over the casserole and lightly mist with olive oil spray.

Bake until golden and bubbly:

Bake for 30 to 35 minutes until you see the sauce bubbling up around the edges and the topping is a beautiful golden brown.

Let it rest before serving:

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

Save

Last winter my neighbor was recovering from surgery and I brought over a pan of this casserole. She texted me the next morning saying she'd eaten it for dinner and then again for breakfast which honestly felt like the highest compliment possible.

Make Ahead Magic

You can assemble the entire casserole up to 24 hours ahead and keep it covered in the refrigerator. Just add a few extra minutes to the baking time since it will be going into the oven cold.

Freezer Friendly

Wrap the unbaked casserole tightly in plastic wrap and aluminum foil before freezing for up to 3 months. Thaw overnight in the refrigerator then bake as directed adding about 10 extra minutes.

Serving Suggestions

A crisp green salad with a bright vinaigrette cuts through the richness perfectly and steamed broccoli or roasted green beans add color without competing with the flavors. You can also serve this over cauliflower rice or brown rice if you want extra carbohydrates.

• Leftovers reheat beautifully in the microwave for 2 to 3 minutes
• The flavors actually develop and taste even better the next day
• This casserole freezes well after baking too if you want portion controlled meals ready to go

Save

There is something so satisfying about serving a dish that feels indulgent but is actually helping you meet your fitness goals. This casserole has saved me on countless busy weeknights.

Common Questions

→ Can I make this ahead of time?

Yes, assemble the entire casserole up to 24 hours in advance and refrigerate. Add 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. Already-baked portions freeze well for 2-3 months in airtight containers.

→ What can I substitute for cottage cheese?

Ricotta cheese works well as a direct substitute. For a dairy-free option, use mashed silken tofu or a plant-based cottage cheese alternative.

→ How do I know when it's done baking?

The casserole is ready when it's bubbling around the edges and the breadcrumb topping is golden brown. The internal temperature should reach 165°F (74°C).

→ Can I use fresh spinach instead of frozen?

Yes, use about 1 pound of fresh spinach. Cook it down in a skillet first, squeeze out excess moisture, then chop before adding to the mixture.

→ Is this suitable for meal prep?

Absolutely. Portion into individual containers and refrigerate for up to 5 days. Reheat in the microwave with a splash of water or broth to maintain creaminess.
