How To Make High-Protein Spinach and Artichoke Chicken Casserole
Bringing this casserole to life is a breeze—just mix, bake, and enjoy! You’ll start by prepping your oven and baking dish, then combine the wholesome ingredients into a creamy filling. Once your pasta is cooked al dente, everything gets stirred together with a splash of chicken broth before baking to bubbly perfection. Follow these steps to create a cheesy, protein-packed dinner that’s sure to impress.
1. Preheat your oven to 375°F (190°C). Grease an 8×8 inch baking dish with olive oil or cooking spray to ensure easy serving.
2. In a large mixing bowl, combine the cooked and shredded chicken, chopped spinach, chopped artichoke hearts, Greek yogurt, mozzarella cheese, Parmesan cheese, minced garlic, onion powder, garlic powder, dried basil, black pepper, and salt. Mix well until all ingredients are evenly incorporated.
3. In a separate pot, bring salted water to a boil and cook the whole wheat pasta according to package instructions until al dente. Drain and immediately add the pasta to the chicken mixture, stirring to combine.
4. Pour in the chicken broth and stir again to make sure every bit of the mixture is well coated and creamy.
5. Transfer the mixture to the prepared baking dish, spreading it out into an even layer.
6. Bake in the preheated oven for about 25–30 minutes, or until the casserole is bubbly and the top turns lightly golden.
7. Remove from the oven and let it cool for a few minutes before serving. This resting time helps the casserole set up for cleaner slices.

Frequently Asked Questions
Got questions? Here are quick answers to common queries about this casserole:
- How long does it take to prepare and cook this High-Protein Spinach and Artichoke Chicken Casserole?
It takes about 15 minutes to prepare—this includes shredding chicken (if not already done), chopping spinach and artichokes, mixing ingredients, and preheating the oven. Baking time is 25–30 minutes at 375 °F (190 °C), so total time is approximately 40–45 minutes.
- How should I store and reheat leftovers?
Let the casserole cool completely, then cover it tightly and store in the refrigerator for up to 3 days. To reheat, place individual portions in a microwave-safe dish and microwave on medium power for 1–2 minutes, stirring halfway through. For a crisp top, reheat in a 350 °F (175 °C) oven for 10–12 minutes until warmed through.
- Can I make this casserole ahead of time?
Yes. Assemble the casserole as directed, cover it tightly with foil or plastic wrap, and refrigerate for up to 24 hours. When ready to bake, remove the cover, add an extra 5 minutes to the baking time if still cold from the fridge, and bake at 375 °F (190 °C) until bubbly and golden.
- How can I adapt this recipe for gluten-free or vegetarian diets?
For gluten-free, substitute whole wheat pasta with your favorite gluten-free penne or rotini. For a vegetarian version, replace shredded chicken with 2 cups of cooked plant-based chicken substitute or extra-firm tofu crumbles, and use vegetable broth instead of chicken broth.
- What are some easy ingredient swaps if I don’t have Greek yogurt or Parmesan?
You can swap Greek yogurt for an equal amount of cottage cheese blended until smooth or for light sour cream. If you’re out of Parmesan, increase the mozzarella by ½ cup and add 1–2 tablespoons of nutritional yeast for extra savory flavor.
- How much protein does each serving provide?
The entire casserole contains roughly 150 g of protein, largely from chicken, Greek yogurt, and cheese. If you divide it into four equal servings, each portion delivers about 35–40 g of protein.
- How can I add more flavor or spice to the casserole?
Stir in ¼–½ teaspoon of red pepper flakes or a few dashes of hot sauce into the mixture before baking. You can also top with sliced jalapeños or drizzle sriracha over each serving for an extra kick.
- Can I prepare this recipe with frozen spinach or canned artichokes?
Yes. If using frozen spinach, thaw and squeeze out excess moisture before chopping and adding. For canned artichokes, drain thoroughly and pat dry with paper towels to prevent excess liquid in the casserole.
