- 1 small yellow onion, chopped
- 2 cloves garlic, minced
- 8 ounces (225g) cremini mushrooms, sliced
- 5 ounces (140g) fresh baby spinach
- 2 cups cooked chicken, shredded (rotisserie chicken works wonderfully!)
- For the Creamy Sauce:
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 2 cups whole milk (or 2%)
- 1 cup chicken broth
- 4 ounces (113g) cream cheese, softened

Step-by-Step Instructions
-
Step 1: Cook the Pasta
Preheat your oven to 375°F (190°C). Bring a large pot of salted water to a boil. Add the pasta and cook according to package directions until al dente. Drain well and set aside.
Small tip: Don’t overcook the pasta, as it will continue to cook in the oven. Al dente is perfect!
-
Step 2: Sauté the Aromatics and Veggies
While the pasta cooks, heat the olive oil in a large skillet or Dutch oven over medium heat. Add the chopped onion and cook until softened, about 3-4 minutes. Stir in the minced garlic and sliced mushrooms, cooking for another 5-7 minutes until the mushrooms are tender and have released their liquid.
Small tip: Make sure your skillet is hot enough to get a nice sear on the mushrooms, which adds depth of flavor.
-
Step 3: Wilt the Spinach and Add Chicken
Add the fresh baby spinach to the skillet with the onions and mushrooms. Cook, stirring occasionally, until the spinach has completely wilted, about 2-3 minutes. Stir in the shredded cooked chicken and remove the skillet from the heat. Set aside.
Small tip: If your skillet isn’t large enough, add the spinach in batches until it all wilts down.
-
Step 4: Make the Creamy Sauce
In a separate medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute, stirring constantly, to create a roux. Gradually whisk in the milk and chicken broth, stirring constantly to prevent lumps. Bring the sauce to a gentle simmer, then reduce heat to low.
Small tip: Whisking continuously is key to a smooth, lump-free sauce.
-
Step 5: Finish the Sauce
Add the softened cream cheese to the simmering sauce and whisk until it’s fully melted and smooth. Stir in the Parmesan cheese, salt, and black pepper. Continue stirring until the Parmesan is melted and the sauce is creamy and well combined. Taste and adjust seasonings if needed.
Small tip: Make sure your cream cheese is at room temperature to help it melt smoothly into the sauce without clumping.
-
Step 6: Combine Everything
Pour the creamy sauce into the skillet with the chicken, mushrooms, and spinach mixture. Add the drained cooked pasta to the skillet as well. Gently stir everything together until all the ingredients are evenly coated with the rich, creamy sauce.
Small tip: Be gentle when mixing to avoid breaking up the pasta too much.
-
Step 7: Assemble and Bake the Casserole
Transfer the entire mixture to a 9×13-inch baking dish. Spread it evenly. Sprinkle the shredded mozzarella cheese generously over the top of the casserole. Place the dish in your preheated oven.
Small tip: For an extra golden top, you can broil for the last minute or two, but watch it carefully!
-
Step 8: Bake to Golden Perfection
Bake for 25-30 minutes, or until the casserole is bubbly around the edges and the cheese topping is melted and beautifully golden brown. Remove from the oven and let it rest for 5-10 minutes before serving.
Small tip: Letting the casserole rest helps the sauce set slightly, making it easier to serve clean portions.
-
Step 9: Rest and Serve
Garnish with fresh chopped parsley before serving. Scoop out generous portions and enjoy this comforting Full Moon Casserole with your loved ones. It’s a meal that truly brings joy to the table!
Small tip: A sprinkle of fresh herbs adds a lovely pop of color and freshness to the rich dish.
Tips & Variations
- Gluten-Free Option: Easily make this recipe gluten-free by using your favorite gluten-free pasta and substituting the all-purpose flour with a gluten-free all-purpose flour blend (like a 1:1 baking flour).
- Vegan or Vegetarian Option: Omit the chicken and use plant-based milk, vegan cream cheese, and vegan shredded cheese. Replace chicken broth with vegetable broth. For protein, add a can of drained and rinsed chickpeas or white beans, or some crumbled plant-based ground “meat.”
- Add More Vegetables or Protein: Feel free to toss in other veggies like diced bell peppers, broccoli florets, or frozen peas during the sautéing step. For extra protein, you can add cooked ground turkey, diced ham, or even some extra beans.
- Spicy Version: For those who love a kick, add ¼ to ½ teaspoon of red pepper flakes to the sauce, or finely dice a small jalapeño and sauté it with the onions and garlic. A dash of hot sauce in the sauce works too!
- Flavor Boost: Stir in a teaspoon of Dijon mustard or a squeeze of fresh lemon juice into the finished sauce for an extra layer of flavor and brightness. A pinch of nutmeg can also enhance the creamy sauce.
