The cheese quality matters here. Sargento or BelGioioso shredded mozzarella melts beautifully without that weird rubbery texture. For Parmesan, grab a wedge from the deli counter—pre-grated has anti-caking agents that make sauces grainy. The pasta should be standard penne (the ridges help hold sauce). Barilla or De Cecco are my go-tos for consistent texture.

No heavy cream? Half-and-half works in a pinch (just reduce the milk by a quarter cup). Want more flavor? Swap the marinara for San Marzano crushed tomatoes. The Dijon can be regular yellow mustard at half the amount. Fresh herbs? Use 1 tbsp chopped basil and oregano instead of the dried seasoning. The butter can be swapped for olive oil if you’re out.

Assemble and bake right away, or cover and refrigerate for up to 24 hours before baking. Leftovers keep 4-5 days in the fridge, reheating best in the oven. Freezes beautifully for 2-3 months—just thaw overnight before reheating.

Step-by-Step Instructions for Creamy Pasta Bake

Here’s the method I use to create this comforting dish with minimal effort and maximum flavor.

Step 1: Cook the Penne Pasta Al Dente

Bring a large pot of salted water to a rolling boil. Add the 12 oz Penne Pasta and cook according to package directions for 1 minute less than the suggested al dente time. This ensures the pasta finishes cooking perfectly in the oven without becoming mushy.

Drain the pasta in a colander but don’t rinse it. The residual starch helps the sauce cling to the pasta. Transfer the cooked pasta to a large bowl and toss immediately with 1 tbsp Unsalted Butter to prevent sticking while you prepare the sauce.

Step 2: Create the Creamy Cheese Sauce Base

In a saucepan over medium heat, melt the remaining 1 tbsp Unsalted Butter. Whisk in the 2 tbsp All-Purpose Flour to form a smooth roux. Cook for 1-2 minutes until the mixture turns a light golden color—this removes the raw flour taste.

Gradually whisk in the 2 cups Heavy Cream and 1 cup Whole Milk, ensuring no lumps remain. Stir in the 3 cloves minced Garlic Cloves, 1 tsp Salt, 0.5 tsp Black Pepper, 1 tsp Dried Italian Seasoning, 1 tsp Dijon Mustard, and 0.25 tsp Nutmeg. Cook for 3-4 minutes until the sauce begins to thicken and coats the back of a spoon.

Step 3: Combine All Elements and Add Cheese

Pour the cream sauce over the cooked pasta and stir to combine evenly. Add the 1.5 cups Marinara Sauce and 2 cups Shredded Mozzarella Cheese, reserving 1 cup for topping. Stir until the cheese is fully melted and the mixture looks creamy and homogeneous.

Taste and adjust seasoning if needed. The sauce should be rich and velvety, with the tang of mustard and warmth of Italian seasoning coming through. If the mixture seems too thick, add a splash of the pasta cooking water to loosen it slightly.

Step 4: Bake to Bubbly Perfection

Transfer the pasta mixture to a greased 9×13-inch baking dish and spread evenly. Sprinkle the reserved 1 cup Shredded Mozzarella Cheese and the 0.75 cup Grated Parmesan Cheese evenly over the top.

Bake in a preheated 375°F oven for 20-25 minutes until the cheese is bubbly and golden brown and the edges are slightly crisp. Let it rest for 5 minutes before serving to allow the sauce to set slightly—this makes it easier to serve neat portions.

Perfect Pairings for This Recipe

Side Dishes

A creamy pasta bake pairs beautifully with light, fresh sides that cut through the richness. Try a crisp garden salad with a tangy vinaigrette or roasted garlic bread to soak up every last bite. For a veggie boost, steamed broccoli or asparagus adds a vibrant touch without overpowering the dish.

Drink Pairings

Balance the creamy, cheesy flavors with a refreshing drink. A chilled Pinot Grigio or Sauvignon Blanc complements the dish perfectly, while a light sparkling water with lemon keeps things crisp. For non-alcoholic options, iced tea or a fruity lemonade adds a zesty contrast.

Complementary Flavors

Enhance your pasta bake with bold, complementary flavors. A sprinkle of red pepper flakes adds heat, while fresh basil or parsley brightens the dish. For extra depth, a drizzle of balsamic glaze or a side of sun-dried tomatoes introduces a tangy, savory note.
