Build 4 Ingredient Pesto Baked Rigatoni Recipe Step by Step

Step 1: Cook the Rigatoni
Start by boiling a large pot of salted water. Once it’s at a rolling boil, add the 1 lb Delallo Rigatoni and cook according to the package instructions until al dente. This usually takes about 10-12 minutes, but check for doneness a minute or two before the time is up. Once cooked, reserve about 1/4 cup of the pasta water before draining the rest in a colander.
Step 2: Mix the Ingredients
In a large mixing bowl, combine the 6.35 ounces Delallo Simply Pesto and 1 cup Delallo Crushed Tomatoes. Stir until they are well mixed. If the mixture seems too thick, add a bit of the reserved pasta water to achieve your desired consistency.
Step 3: Combine the Pasta and Sauce
Add the drained rigatoni to the pesto and tomato mixture. Gently toss to coat all the pasta evenly. If necessary, add more reserved pasta water to help the sauce coat the rigatoni.
Step 4: Bake the Rigatoni
Preheat your oven to 350°F (175°C). Transfer the pasta mixture to a greased baking dish. Sprinkle the 2 cups shredded mozzarella cheese evenly over the top. Bake in the preheated oven for about 20-25 minutes, or until the cheese is melted and bubbly, and a light golden brown.
Step 5: Garnish and Serve
Once out of the oven, let the dish cool for a few minutes. Garnish with freshly chopped basil. Serve hot and enjoy your delicious 4 Ingredient Pesto Baked Rigatoni Recipe!
Spring–Summer–Fall–Winter Ideas

- Spring: Add fresh asparagus or peas to the pasta for a pop of color and freshness.
- Summer: Toss in roasted cherry tomatoes and zucchini for a seasonal twist.
- Fall: Mix in sautéed mushrooms and spinach for a hearty dish.
- Winter: Incorporate cooked sausage or shredded rotisserie chicken for added protein.
Mistakes Even Pros Make
- Overcooking the pasta: Always undercook your pasta slightly, as it will continue to cook while baking.
- Not reserving enough pasta water: This can help adjust the sauce’s consistency later on.
- Skipping the cheese on top: A generous layer of cheese is essential for that delicious baked texture.
- Not letting the dish cool before serving: Allowing it to sit for a few minutes helps the dish set and makes serving easier.
Storing, Freezing & Reheating
