Pasta & Chicken
- 12 oz (340 g) penne or rigatoni
- 2 large boneless, skinless chicken breasts, cubed
Vegetables & Greens
- 3 cups baby spinach, loosely packed
- 1 small onion, finely diced
- 2 cloves garlic, minced
Cream Sauce
- 3 tablespoons unsalted butter
- 3 tablespoons all‑purpose flour
- 2 cups whole milk, warmed
- ½ cup grated Parmesan cheese
Seasonings & Topping
- ½ teaspoon smoked paprika
- ¼ teaspoon freshly grated nutmeg
- Salt and freshly ground black pepper, to taste

The butter‑flour roux forms the backbone of the sauce, giving it that luxurious silkiness, while the milk adds body without heaviness. Parmesan introduces a subtle umami depth, and the smoked paprika brings a whisper of warmth that complements the spinach’s earthiness. Together, these ingredients create a cohesive, comforting bake that feels both indulgent and balanced—perfect for a brunch that feels special.
Step-by-Step Instructions
Preparing the Base
Begin by bringing a large pot of salted water to a boil. Cook the penne or rigatoni until it is al dente, usually 8–9 minutes. While the pasta cooks, toss the cubed chicken with a pinch of salt and pepper. Heat 1 tablespoon olive oil in a wide skillet over medium‑high heat, then sear the chicken for 4–5 minutes, turning once, until golden and just cooked through. Transfer the chicken to a plate and set aside.
Cooking Process
- Sauté Aromatics. In the same skillet, add the remaining 1 tablespoon olive oil. Reduce heat to medium, then add the diced onion. Cook, stirring occasionally, for 3–4 minutes until translucent. Add the minced garlic and cook an additional 30 seconds, being careful not to let it brown. This step builds the flavor foundation for the sauce.
- Make the Roux. Sprinkle the flour over the softened onions and stir to coat. Cook for 1–2 minutes, allowing the flour to toast lightly; this eliminates any raw flour taste and creates a glossy base for the cream.
- Incorporate Milk. Gradually whisk in the warmed milk, a little at a time, to prevent lumps. Continue whisking until the mixture thickens, about 4–5 minutes. You’ll know it’s ready when it coats the back of a spoon.
- Season & Add Cheese. Stir in the smoked paprika, nutmeg, and half of the Parmesan. Adjust salt and pepper to taste. Then fold in the shredded mozzarella, allowing it to melt into the sauce for extra silkiness.
- Combine Everything. Add the cooked pasta, seared chicken, baby spinach, and sautéed onion‑garlic mixture to the sauce. Toss gently until the spinach wilts and everything is evenly coated. Transfer the mixture to a greased 9‑x‑13‑inch casserole dish, spreading it into an even layer.
Finishing Touches
Sprinkle the remaining Parmesan over the top, then place the dish in a pre‑heated 375°F (190°C) oven. Bake for 20–25 minutes, or until the surface is golden brown and the sauce bubbles at the edges. Remove from the oven, let the bake rest for 5 minutes, then garnish with fresh parsley if desired. Serve hot, straight from the dish, for a comforting brunch experience.
Tips & Tricks
Perfecting the Recipe
Use a Hot Pan for the Chicken. A properly heated skillet creates a caramelized crust that locks in juices, preventing dry bites.
Don’t Overcook the Pasta. Al dente pasta continues to cook in the oven, ensuring it stays firm and doesn’t turn mushy.
Warm the Milk. Adding warm milk to the roux prevents lumps and speeds up thickening, giving a smoother sauce.
Rest Before Serving. A short 5‑minute rest lets the sauce settle and the cheese finish setting, making slicing cleaner.
Flavor Enhancements
Add a splash of dry white wine to the sauce after the roux for subtle acidity. A pinch of red‑pepper flakes introduces gentle heat without overpowering the dish. Finish with a drizzle of extra‑virgin olive oil just before serving for a bright, fruity note.
Common Mistakes to Avoid
Skipping the resting period leads to a runny sauce that slides off the plate. Also, avoid high heat when adding the milk; it can cause the sauce to curdle. Finally, be sure to season each layer—under‑seasoned sauce can make the whole bake taste flat.
Pro Tips
Grate Cheese Fresh. Freshly grated Parmesan melts more evenly and offers a brighter flavor than pre‑grated packets.
Use a Handheld Mixer. When whisking the sauce, a small immersion blender creates a perfectly smooth texture in seconds.
Layer the Cheese. Adding half the mozzarella inside the bake and the rest on top ensures a gooey interior and a crispy golden crust.
Prep Ahead. Assemble the casserole the night before, cover, and refrigerate; bake directly from the fridge for a hassle‑free brunch.
Variations
Ingredient Swaps
Replace chicken with bite‑size turkey sausage or cubed pork tenderloin for a richer profile. Swap spinach for kale or Swiss chard if you prefer a sturdier green. For a vegetarian take, use firm tofu cubes marinated in soy sauce and smoked paprika. Experiment with different cheeses—Gruyère or sharp cheddar add a distinctive tang.
Dietary Adjustments
Use gluten‑free pasta and ensure the flour is a certified gluten‑free blend for a celiac‑friendly version. Swap whole milk for unsweetened almond or oat milk and use dairy‑free cheese to keep the dish dairy‑free. For a low‑carb approach, replace pasta with spiralized zucchini or shirataki noodles.
Serving Suggestions
Pair the bake with a light arugula salad tossed in lemon vinaigrette to cut through the richness. A side of roasted cherry tomatoes adds acidity, while toasted garlic bread offers a crunchy, buttery contrast. For a brunch spread, serve alongside fresh fruit and a sparkling mimosa.
Storage Info
Leftover Storage
Allow the bake to cool to room temperature, then cover tightly with foil or transfer to an airtight container. Refrigerate for up to 3 days. For longer keeping, portion the leftovers into freezer‑safe containers, wrap with a layer of foil, and freeze for up to 3 months. Re‑seal any exposed edges to prevent freezer burn.
Reheating Instructions
Preheat the oven to 350°F (175°C). Place the leftover portion in a shallow baking dish, cover with foil, and bake for 15–20 minutes until heated through. For a quicker option, microwave on medium power for 2–3 minutes, stirring halfway, and add a splash of milk or broth to revive the sauce’s creaminess.
