Instructions

Step 1: Cook the Pasta

  1. Bring a large pot of salted water to a boil.

  4. Drain and set aside.

Step 2: Prepare the Spinach Mixture

  1. Melt the butter in a large skillet over medium heat.
  2. Add the chopped onion and cook for 3–4 minutes.
  3. Add the minced garlic and cook for 30 seconds.
  4. Add the spinach and cook until wilted, about 2 minutes.

Step 3: Make the Cream Sauce

  1. Sprinkle the flour over the spinach mixture.
  2. Stir continuously for 1 minute.
  3. Slowly pour in the milk while whisking.
  4. Add the heavy cream.

  6. Add the salt, pepper, and nutmeg.

Step 4: Add the Cheese

  1. Reduce the heat to low.
  2. Stir in the ricotta cheese.
  3. Add 1 cup mozzarella and ½ cup Parmesan.

Step 5: Combine the Pasta and Sauce

  1. Preheat the oven to 375°F (190°C).

  3. Toss until all the pasta is evenly coated.

Step 6: Bake

  1. Transfer the pasta mixture to a lightly greased 9 × 13-inch baking dish.
  2. Sprinkle the remaining mozzarella and Parmesan over the top.
  3. Bake for 20–25 minutes.

  1. Remove from the oven.
  2. Let the casserole rest for 5 minutes.
  3. Garnish with fresh parsley.
  4. 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.

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
  • Baking for too long
  • Using too little sauce

To maintain creaminess, slightly undercook the pasta and avoid overbaking.
