Ingredients for baked red sauce pasta

One-pot magic starts with these 14 simple ingredients that deliver restaurant-quality flavor.

The celery crown is the star here—look for thick, crisp stalks at the grocery store. Whole Foods or your local market usually have the best selection. If you can't find thick celery, use 6-8 regular stalks and trim the leaves off for extra flavor. The San Marzano tomatoes are non-negotiable for that sweet, rich tomato flavor—Trader Joe's carries them canned if you don't want to hunt for them. For the pasta, penne or rigatoni work best—their shape holds up perfectly to baking. I always grab the De Cecco brand when I'm at Costco—it's my go-to for baked pasta dishes.

No heavy cream? Full-fat coconut milk works in a pinch, though it'll be slightly lighter. Fresh basil? Dried oregano at half the amount gets you close. The Parmesan needs to be freshly grated—pre-grated gets clumpy and doesn't melt right. For extra richness, add a splash of half-and-half to the sauce. Want more depth? Add a pinch of sugar to balance the acidity in the tomatoes. The butter and olive oil combo gives that perfect sauce texture—don't skip either. If you're short on time, use butter-flavored oil instead of regular butter.

This dish reheats beautifully—honestly tastes better the next day once everything melds. Keeps for 4-5 days in the fridge, freezes for 3 months. I always make a double batch and portion it into containers so lunches are sorted for the week. The celery crown gets extra crispy when reheated, so if you're serving it cold, make it fresh. For extra flavor, add a sprinkle of Parmesan and red pepper flakes right before serving—trust me on this.

Step-by-step instructions for baked red sauce pasta

Here's how to create a rich, creamy tomato sauce that bakes right in the pasta—no separate pot needed.

Heat the 0.5 cup olive oil and 4 tbsp butter in a large oven-safe skillet over medium heat. Add the 1 whole yellow onion and 4 whole celery stalks, sliced into ¼-inch pieces. Cook for 5-6 minutes until the vegetables soften and become translucent.

Add the 4 cloves minced garlic and stir for 30 seconds until you can smell that wonderful garlic aroma. Here's the thing—don't let the garlic burn. It should be fragrant but not browned. This is the flavor foundation for your entire dish, so take your time with this step.

Pour in the 28 oz San Marzano crushed tomatoes and stir to combine with the vegetables. Add the 1 tbsp dried oregano, 1.5 tsp salt, 0.5 tsp black pepper, and 0.5 tsp red pepper flakes. Bring the mixture to a gentle simmer and cook uncovered for 10 minutes to allow the flavors to meld.

While this simmers, make sure to stir occasionally to prevent sticking. You'll notice the sauce will thicken slightly as the tomatoes break down. This is normal and actually helps create a more concentrated flavor. The goal here is to develop the tomato base before adding the pasta and cream.

Add the 1.5 lbs penne or rigatoni to the skillet and stir to coat the pasta completely with the tomato mixture. Pour in 2 cups of water (just enough to cover the pasta) and bring to a boil. Once boiling, reduce heat to medium-low and simmer uncovered for 12-15 minutes, stirring occasionally.

You'll know the pasta is cooking properly when it starts to absorb the liquid and the sauce becomes thicker. The pasta should be tender but still have a slight bite—it will finish cooking in the oven. If the sauce looks too dry, add another ½ cup of water to keep it moist. This step is where the magic happens as the pasta absorbs the rich tomato flavor.

Once the pasta is nearly tender, reduce heat to low and stir in the 1 cup heavy cream and 1 cup freshly grated Parmesan cheese. Cook for another 2-3 minutes until the sauce becomes creamy and velvety. The cheese should melt completely and create a luxurious coating on the pasta.

Here's where it gets fun—taste the sauce and adjust seasoning if needed. You might need a little more salt or pepper to balance the richness of the cream. The sauce should be thick enough to coat the back of a spoon but still be pourable. If it's too thick, add a splash of pasta water to loosen it to your desired consistency.

Preheat your oven to 375°F. Transfer the skillet to the oven and bake uncovered for 15-20 minutes until the top is golden brown and bubbly. The pasta will finish cooking in the oven, and the sauce will develop a beautiful caramelized crust.

While it bakes, prepare the celery crown garnish by cutting the remaining 2 whole celery stalks (if any) into thin ribbons or small pieces. Once the pasta is golden and bubbling, remove from the oven and sprinkle with the 0.25 cup chopped fresh basil leaves. The basil adds a bright, fresh contrast to the rich tomato-cream sauce.

Let the pasta rest for 2-3 minutes before serving. This allows the sauce to thicken slightly and makes it easier to serve. The result is a one-pot pasta dish with a creamy tomato sauce that has a beautiful golden crust on top and a crisp celery garnish for texture and freshness.

Regional styles of this recipe

Classic Italian Baked Pasta

This dish finds its roots in traditional Italian baked pasta techniques, where the pasta cooks directly in the sauce before baking. In Naples, where pasta originated, this method was born from necessity—using minimal ingredients to create maximum flavor.

The San Marzano tomatoes used here are a nod to the volcanic soil of Campania, where these tomatoes grow sweeter and more flavorful than others. 🍅

In Rome, this style of baked pasta often includes pecorino cheese instead of Parmesan, giving it a sharper, nuttier flavor. For an authentic Roman touch, substitute ½ cup grated pecorino for half the Parmesan.

The Romans also love adding garlic and chili flakes to their baked pasta, so increase the red pepper flakes to 1 tsp for a spicier kick.

New York-Style Tomato Cream

This variation takes inspiration from New York Italian-American cuisine, where rich, creamy tomato sauces are king. The addition of heavy cream transforms this into a tomato cream sauce—a staple in NYC Italian restaurants.

For an extra layer of flavor, add 1 tbsp tomato paste to the sautéed vegetables before adding the crushed tomatoes. This creates a deeper, more concentrated tomato flavor that’s perfect for the creamy finish.

In NYC, it’s common to serve baked pasta with a side of garlic bread or a simple green salad. For a true New York touch, sprinkle the baked pasta with crumbled bacon bits or Italian sausage crumbles before serving.

This adds a smoky, savory depth that’s a hallmark of NYC Italian-American cooking.

Southern Italian Rustic Style

For a Southern Italian twist, focus on rustic, hearty flavors. In regions like Sicily and Calabria, baked pasta often includes olives, capers, and anchovies for a briny contrast. Add ¼ cup Kalamata olives and 1 tbsp capers to the tomato sauce while simmering.

For extra depth, stir in 2 anchovy fillets (finely chopped) along with the garlic. These ingredients add a salty, umami punch that balances the creaminess.
