Manicotti Recipe White Sauce: Baked Pasta With Creamy Ricotta Filling

There’s something deeply satisfying about baking a pan of manicotti with creamy white sauce, knowing it’ll feed a hungry crowd with minimal effort.

I’ve tested this recipe in my tiny Boston kitchen more times than I can count, perfecting the balance between the creamy ricotta filling and the velvety white sauce that ties everything together.

What emerges from the oven is pasta tubes stuffed with rich, cheesy filling, all blanketed in a silky sauce that bubbles at the edges. It’s comfort food at its finest.

Serve it with a simple green salad and crusty bread for soaking up every last bit of sauce.

The ricotta is the star here. Whole milk ricotta from Whole Foods or BelGioioso has that ultra-creamy texture you need—low-fat versions get watery. I grab mine at Market Basket in Boston (the Italian section has the good stuff). For the Parmesan, skip the pre-grated—it’s coated in anti-caking agents that make the sauce grainy. Freshly grate a wedge instead (worth the extra minute).

No spinach? Frozen works just as well—just squeeze out ALL the water (or you’ll have soggy filling). Swap mozzarella for fontina or provolone for extra gooeyness. The milk can be half-and-half at half the volume for an even richer sauce. If you’re out of nutmeg, a pinch of white pepper adds a similar warmth. The eggs help bind the filling—don’t skip them unless you’re going vegan (then use flax eggs).

Assemble the manicotti up to 24 hours ahead—cover tightly and refrigerate. Bake straight from the fridge (add 10 minutes to cooking time). Leftovers keep 4-5 days in the fridge or freeze for 3 months. Reheat covered to keep the sauce silky.

Step-by-Step Instructions for Manicotti with White Sauce

Here’s my foolproof method for assembling and baking this dish to creamy perfection.

Step 1: Prepare the Ricotta Filling

In a large bowl, combine the 2 cups Whole Milk Ricotta Cheese, 2 whole Large Eggs, 1 cup Parmesan Cheese, 10 oz Fresh Spinach, 2 cloves Garlic Cloves, ½ tsp Black Pepper, and ½ tsp Salt. I like to mix this with a wooden spoon until everything is thoroughly incorporated and the spinach is evenly distributed.

The eggs act as a binder to hold the filling together during baking. Don’t skip this step—it’s what prevents the filling from becoming grainy. You’ll know it’s ready when the mixture holds its shape when you press it with the spoon.

Step 2: Make the Creamy White Sauce

In a saucepan over medium heat, melt the ½ cup Unsalted Butter. Add the ¼ cup All-Purpose Flour and whisk constantly for 1-2 minutes until the mixture turns light golden brown. This is your roux—the foundation of the white sauce.

Slowly pour in the 4 cups Whole Milk, whisking continuously to prevent lumps from forming. Stir in the remaining 1 tsp Salt and ¼ tsp Ground Nutmeg. Cook for 5-7 minutes until the sauce thickens enough to coat the back of a spoon. The nutmeg adds a subtle depth that makes this sauce special.

Step 3: Assemble the Manicotti

Spread 1 cup Marinara Sauce on the bottom of a 9×13-inch baking dish. I use the no-boil manicotti shells here—just fill the 12 pieces Manicotti Shells with the ricotta mixture using a spoon or piping bag. Place them seam-side up in the dish, nestling them into the marinara.

Pour the white sauce evenly over the filled shells, making sure they’re completely covered. Sprinkle the 2 cups Mozzarella Cheese on top. This layer will melt into a beautiful, bubbly golden crust during baking.

Step 4: Bake to Bubbly Perfection

Cover the dish with foil and bake at 375°F for 30 minutes. Then, remove the foil and bake for another 15-20 minutes until the cheese is bubbly and golden brown and the pasta is cooked through.

You’ll know it’s done when the sauce is actively bubbling at the edges and the top has developed a light golden crust. Let it rest for 5-10 minutes before serving—this gives the filling time to set and makes it easier to slice.

Garnish with the ¼ cup Fresh Parsley and serve warm. The contrast between the creamy filling, tangy white sauce, and melted cheese is what makes this dish unforgettable.

Pro Cooking Tips for Perfect Results

Prevent Lumpy Sauce

Whisk the flour and butter for a full 2 minutes until golden before adding milk. I use a flat whisk for better contact with the pan bottom. Pour milk in a slow stream while whisking constantly to create a smooth base. 💡

Fill Without Breaking

Use a ziplock bag with the corner snipped off to pipe filling into shells—it’s cleaner than spooning. Place filled tubes seam-side up in the dish to prevent bursting. I tested this method 5 times in my tiny kitchen to perfect it.

Sauce Consistency Check

Your white sauce should coat the back of a spoon but still drip slowly. If too thick, whisk in ¼ cup warm milk. Too thin? Simmer 2-3 more minutes. The nutmeg should be subtle—just a hint of warmth.

Baking Covered First

Always cover with foil for the first 30 minutes at 375°F. This steams the pasta perfectly. Uncover for the final 15-20 minutes to let the cheese brown. Look for bubbling at the edges as your doneness cue.

Rest Before Serving

Let it rest 5-10 minutes after baking. This lets the filling set so it doesn’t ooze out when sliced. I learned this the hard way with that pot pie disaster—patience pays off. 🥗

Cheese Melting Tip

Sprinkle mozzarella over the white sauce just before baking, not earlier. This prevents it from absorbing too much liquid. For extra browning, broil for 1-2 minutes at the end, watching closely.
