Instructions
Step 1: Cook the Pasta
- Bring a large pot of salted water to a boil.

Step 2: Prepare the Spinach Mixture
- Melt the butter in a large skillet over medium heat.
- Add the chopped onion and cook for 3–4 minutes.

Step 3: Make the Cream Sauce
- Sprinkle the flour over the spinach mixture.
- Stir continuously for 1 minute.
- Slowly pour in the milk while whisking.

- Stir until the sauce thickens, about 4–5 minutes.
- Add the salt, pepper, and nutmeg.
Step 4: Add the Cheese
- Reduce the heat to low.
- Stir in the ricotta cheese.
- Add 1 cup mozzarella and ½ cup Parmesan.
- Stir until the cheeses are melted and incorporated.
Step 5: Combine the Pasta and Sauce
- Preheat the oven to 375°F (190°C).

Step 6: Bake
- Transfer the pasta mixture to a lightly greased 9 × 13-inch baking dish.

Step 7: Serve
- Remove from the oven.
- Let the casserole rest for 5 minutes.
- Garnish with fresh parsley.
- Serve warm.
Chef’s Notes
- Slightly undercook the pasta to prevent it from becoming mushy during baking.
- Whole milk produces a richer sauce, but reduced-fat milk can be substituted.
- Fresh spinach is preferred, but frozen spinach works well if thoroughly drained.
- Nutmeg enhances the flavor of cream sauces without overpowering the dish.
- Allowing the casserole to rest before serving helps the sauce set.

Frequently Asked Questions (Q&A)

Yes. Penne, ziti, fusilli, or shells are excellent alternatives.
Can I make this recipe gluten-free?
Absolutely. Use gluten-free pasta and replace the all-purpose flour with a gluten-free thickener.
How long will leftovers last?
Store leftovers in an airtight container in the refrigerator for 3–4 days.
Can I make it without heavy cream?
Yes. Replace the heavy cream with additional milk, half-and-half, or evaporated milk for a lighter version.
Why did my sauce become dry?
The most common causes are:
- Overcooking the pasta
