Why this 4 Ingredient Pesto Baked Rigatoni Recipe works

Three things make this all come together: texture, balance, and convenience. The ridged Delallo rigatoni holds sauce in every crevice. Delallo Simply Pesto adds a bright, herby backbone without the need to blitz fresh basil and pine nuts. Crushed tomatoes introduce tang and body so the pesto doesn’t overpower, while mozzarella provides that irresistible, pull-apart, golden finish. A small amount of reserved pasta water helps loosen sauces and emulsify pesto into the crushed tomatoes so every tube is coated perfectly.

The result is a dish that tastes like it took longer than it did—complex, cozy, and baked to bubbly perfection. This 4 Ingredient Pesto Baked Rigatoni Recipe proves that a handful of quality ingredients can create something memorable.

Ingredients

• 1 lb Delallo Rigatoni
• 6.35 ounces Delallo Simply Pesto (1 jar)
• 1 cup Delallo Crushed Tomatoes
• 1/4 cup reserved pasta water (might not use the entire 1/4 cup)
• 2 cups shredded mozzarella cheese
• fresh basil, chopped

Equipment

• Large pot for boiling pasta
• Colander or slotted spoon
• Large mixing bowl
• 9×13 or similar baking dish
• Wooden spoon or spatula
• Measuring cups

Prep tips before you start

• Preheat your oven to 375°F (190°C). A hot oven helps the cheese brown evenly.
• Bring a large pot of salted water to a rolling boil before adding the rigatoni.
• Measure out your pesto jar and crushed tomatoes so everything is ready to go when the pasta is cooked.
• Shred the mozzarella if it isn’t pre-shredded; freshly shredded melts best and gives a lovely texture.

Step-by-step instructions

1. Bring a large pot of water to a vigorous boil and salt it generously. Add 1 lb Delallo Rigatoni and cook until al dente—about one to two minutes less than the package’s recommended time—so the pasta holds its shape while baking.
2. Reserve up to 1/4 cup of the pasta cooking water before draining. You might not use the entire amount, but having it on hand lets you loosen the sauce as needed. Drain the rigatoni in a colander and return it briefly to the pot off the heat.
3. In a large mixing bowl, combine 6.35 ounces Delallo Simply Pesto (one jar) and 1 cup Delallo Crushed Tomatoes. Stir until they are evenly blended and create a uniform sauce. If the mixture seems too thick or stiff, add a tablespoon or two of the reserved pasta water to loosen it; continue adding small amounts until the sauce reaches a smooth, coatable consistency but do not exceed the reserved 1/4 cup unless absolutely necessary.
4. Add the drained rigatoni to the bowl with the pesto-tomato mixture. Toss gently but thoroughly so each piece of rigatoni is well coated. The goal is even coverage—no dry tubes. If you notice clumps of sauce, add another teaspoon of reserved pasta water and stir until distributed.
5. Transfer the coated rigatoni into a 9×13 or similar baking dish. Spread it into an even layer so the top will bake uniformly.
6. Sprinkle 2 cups shredded mozzarella cheese evenly over the top of the rigatoni. Make sure to cover the surface so the cheese melts into a golden, bubbly layer. For extra coverage, tap the dish gently to settle the cheese into gaps between pasta tubes.
7. Bake in the preheated 375°F (190°C) oven for about 20–25 minutes, until the cheese is melted, bubbling, and slightly golden on top. If you prefer a very browned top, switch to broil for 1–2 minutes at the end—watch closely to prevent burning.
8. Remove the baking dish from the oven and let it rest for 5 minutes. This brief rest helps the sauce set slightly and makes serving easier.
9. Just before serving, scatter chopped fresh basil over the top for a bright finish. Slice and serve warm, spooning out cheesy rigs that still hold a little saucy goodness inside each tube.

Serving suggestions

This 4 Ingredient Pesto Baked Rigatoni Recipe shines with minimal accompaniments. A crisp green salad dressed with lemon and olive oil adds freshness and crunch. Serve with a side of crusty bread or garlic-rubbed slices to scoop up any leftover sauce. For a heartier meal, pair with roasted vegetables or a simple white bean salad.

Make-ahead and storage

• To prepare in advance: Assemble the rigatoni through step 6, cover, and refrigerate. When ready to bake, remove the cover, bake at 375°F (190°C) for 25–30 minutes, adding a few extra minutes if starting from cold.
• Leftovers: Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. Reheat covered in a 350°F (175°C) oven until warmed through, or microwave individual portions with a damp paper towel on top to prevent drying.
• Freezing: For longer storage, freeze in a freezer-safe container for up to one month. Thaw overnight in the fridge before reheating in the oven to retain texture.

Flavor variations and add-ins

Although this 4 Ingredient Pesto Baked Rigatoni Recipe is perfect as-is, it’s versatile if you want to customize. Stir a cup of cooked, shredded chicken or a can of drained white beans into the pasta before baking for extra protein. Add a handful of baby spinach or roasted cherry tomatoes for color and nutrition—toss them in with the pasta so they wilt slightly before baking. A sprinkle of grated Parmesan or pecorino on top of the mozzarella brings a savory depth if you like a more layered cheese flavor.

Tips for the best results

• Cook the rigatoni just shy of fully tender so it doesn’t turn mushy in the oven.
• Reserve pasta water: it’s a simple trick to make jarred pesto and crushed tomatoes combine into a silky sauce.
• Spread pasta evenly in the dish so the cheese browns uniformly and each portion looks picture-perfect.
• Use freshly shredded mozzarella when possible for superior melt and texture.
• Allow the baked rigatoni to rest briefly—this makes slicing cleaner and serving neater.
