Ingredients
The magic of this dish lies in the balance of fresh greens, rich cheeses, and a silky base. Pasta shells provide a sturdy pocket for the sauce, while fresh spinach adds a pop of color and nutrients. A blend of mozzarella, Parmesan, and cream cheese creates layers of melt‑in‑your‑mouth richness. Finally, aromatics like garlic and nutmeg elevate the flavor profile without overpowering the delicate spinach.
Main Ingredients
- 12 oz (340 g) jumbo pasta shells
- 4 cups (120 g) fresh baby spinach, roughly chopped
- 1 cup (240 ml) heavy cream
Cheese Blend
- 1 cup (100 g) shredded mozzarella
- ½ cup (50 g) grated Parmesan
- ½ cup (115 g) cream cheese, softened
Sauce & Seasonings
- 2 tbsp unsalted butter
- 2 tbsp all‑purpose flour
- 2 cloves garlic, minced
- ¼ tsp freshly grated nutmeg
- Salt and freshly ground black pepper, to taste
Together, these components create a sauce that is both lush and balanced. The butter and flour form a classic roux, giving the sauce body, while the cream, cheese, and spinach meld into a velvety coating. A pinch of nutmeg adds warmth, and the garlic provides a subtle aromatic backbone, ensuring every bite is layered with flavor.
Step-by-Step Instructions
Cooking the Pasta Shells
Bring a large pot of salted water to a rolling boil. Add the jumbo shells and cook for 9‑10 minutes, or until al dente. Drain, drizzle with a teaspoon of olive oil to prevent sticking, and set aside. Properly cooked shells will hold their shape and create a perfect pocket for the sauce.
Preparing the Spinach‑Cheese Béchamel
- Make the Roux. In a medium saucepan over medium heat, melt 2 tbsp unsalted butter. Once foaming, whisk in 2 tbsp all‑purpose flour and cook for 1‑2 minutes, stirring constantly. This eliminates raw flour taste and creates the thickening base.
- Incorporate the Cream. Slowly pour 1 cup heavy cream while whisking vigorously to avoid lumps. Continue whisking until the mixture thickens and coats the back of a spoon, about 3‑4 minutes.
- Add Aromatics & Spinach. Reduce heat to low, stir in 2 cloves minced garlic and ¼ tsp freshly grated nutmeg. Add the chopped spinach and cook until wilted, about 2 minutes. The spinach will blend into the sauce, giving it a beautiful green hue.
- Fold in the Cheese. Remove the pan from heat. Stir in ½ cup cream cheese, 1 cup shredded mozzarella, and ½ cup grated Parmesan until fully melted and smooth. Season with salt and pepper to taste. This step creates the signature creamy richness.
Assembling & Baking
- Combine Pasta and Sauce. In a large mixing bowl, gently toss the cooked shells with the spinach‑cheese béchamel, ensuring each shell is evenly coated. This step guarantees consistent flavor in every bite.
- Transfer to Baking Dish. Lightly grease a 9‑inch square baking dish. Spread the coated shells in an even layer, pressing lightly so they sit snugly together.
- Top with Extra Cheese. Sprinkle an additional ¼ cup mozzarella over the top. This creates a golden, bubbling crust when baked.
- Bake. Preheat the oven to 375°F (190°C). Bake the dish for 15‑18 minutes, or until the cheese on top is melted, lightly browned, and the sauce is bubbling around the edges.
- Rest & Serve. Remove from the oven and let the casserole rest for 5 minutes. This allows the sauce to thicken slightly, making it easier to serve without spilling.
Tips & Tricks
Perfecting the Recipe
Use Fresh Spinach. Fresh leaves wilt quickly and blend smoothly, giving the sauce a brighter color and fresher taste than frozen alternatives.
Don’t Over‑Cook the Pasta. Al dente shells retain their shape during baking, preventing a mushy texture once the sauce thickens.
Season the Sauce Early. Add a pinch of salt while whisking the roux; this layers seasoning throughout the béchamel.
Rest Before Baking. Letting the coated shells sit for 5 minutes before they hit the oven helps the sauce adhere better.
Flavor Enhancements
Finish the dish with a drizzle of extra‑virgin olive oil and a squeeze of fresh lemon juice for brightness. A pinch of crushed red‑pepper flakes adds a subtle heat that lifts the creamy base without overwhelming it.
Common Mistakes to Avoid
Avoid adding cold cream directly to a hot roux—it can cause lumps. Instead, temper the cream by whisking in a small amount of hot sauce first. Also, resist the urge to over‑bake; a long bake dries out the shells and makes the sauce gritty.
Pro Tips
Grate Cheese Fresh. Freshly grated Parmesan releases more flavor and melts more smoothly than pre‑shredded varieties.
Use a Hand‑Held Mixer for the Béchamel. It creates a uniform texture and prevents lumps, especially when incorporating cream cheese.
Finish with Fresh Herbs. A sprinkle of chopped basil or parsley just before serving adds color and a fragrant lift.
Reserve a Cheese Topping. Keep a small amount of mozzarella aside to add after baking for an extra gooey finish.
Variations
Ingredient Swaps
Replace mozzarella with provolone for a sharper melt, or use gouda for a smoky note. Swap heavy cream for half‑and‑half if you prefer a lighter sauce. For added protein, fold in cooked, diced chicken breast or crumbled Italian sausage before baking.
Dietary Adjustments
Choose gluten‑free pasta shells to keep the dish safe for gluten sensitivities. Use dairy‑free cream cheese and a plant‑based cheese blend for a vegan version, and substitute almond milk thickened with a cornstarch slurry for the heavy cream.
Serving Suggestions
Pair the creamy shells with a crisp arugula salad dressed in lemon vinaigrette, or serve alongside roasted garlic bread for extra soak‑up power. A side of sautéed cherry tomatoes adds acidity that balances the richness of the cheese sauce.
Storage Info
Leftover Storage
Allow the casserole to cool to room temperature, then transfer it to an airtight container. Refrigerate for up to 4 days. For longer keeping, portion into freezer‑safe bags, lay flat, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating Instructions
Reheat in a preheated 350°F (175°C) oven, covered with foil, for 15‑20 minutes until steaming hot. Uncover for the last 5 minutes to re‑crisp the cheese topping. In a microwave, heat individual portions on medium power for 2‑3 minutes, stirring halfway and adding a splash of milk or broth to restore creaminess.
