A Few Notes About this Vegetarian Baked Rigatoni
- Rigatoni is a tube-shaped pasta of varying lengths and diameters, which originated in Italy. It’s larger than penne and ziti, and sometimes slightly curved, though not as curved as elbow macaroni. That said, if you need to substitute penne or ziti for the rigatoni in this recipe, feel free! Just make sure that you follow the cooking instructions for very al dente penne or ziti, according to your specific package.
- Use an entire 1-lb. box of dry pasta. I like “mezzi rigatoni” which is slightly shorter than regular rigatoni (and therefore easier to eat without cutting).
- Undercook the pasta slightly, because it will continue to cook while it bakes in the oven. You don’t want to end up with overdone, mushy rigatoni. For instance, if my box of rigatoni suggests 12-14 minutes for al dente, I boil the pasta for 11 minutes.
- Sour cream might seem like an unusual addition to this baked rigatoni recipe; however, this ingredient gives the sauce a creamy, tangy, rich mouthfeel that’s reminiscent of the bechamel sauce or ricotta cheese that you’ll often find in lasagna or baked ziti dishes. Make sure to use the full-fat variety, and allow it to come to room temperature for the easiest blending.
How to Make a Simple Baked Rigatoni Recipe
This vegetarian pasta bake is a weeknight wonder! You don’t need too many special ingredients, and it comes together quickly. You’ll find detailed directions in the recipe card below, but here’s the overview:
- Cook the pasta in a large pot of well-salted boiling water, which is your only chance to really season the rigatoni. I also recommend that you boil the pasta for 1 minute less than the package directions for al dente. This way the pasta will still have a firm bite, so that it doesn’t get overdone when it continues baking in the oven.
- Stir in the jar of marinara sauce and the sour cream. Pick a high-quality store-bought brand for a great shortcut. I like Rao’s marinara, but any variety will work. Taste and season with salt and pepper.
- Transfer the pasta mixture to a greased 13 x 9-inch casserole dish.
- Top with a layer of shredded mozzarella cheese and grated Parmesan cheese.
- In a small bowl, stir together the breadcrumbs, melted butter, and garlic powder.
- Sprinkle the breadcrumb mixture on top of the casserole.
- Bake, uncovered, in a 375°F oven until golden and bubbly. This recipe has plenty of sauce and cheese on top to keep the baked rigatoni from drying out. Be careful that you don’t bake it for too long, though. Since all of the ingredients are already cooked, the dish will only need about 20-25 minutes in the oven. It should get hot, bubbly, and slightly crispy on the edges. Cover loosely with foil if the topping starts to get too dark.
- Let stand for 5-10 minutes before serving.
- Garnish with fresh herbs, crushed red pepper flakes, and extra Parmesan cheese, if desired.
Serving Suggestions
Pair the rigatoni bake with a handful of side dishes to round out the meal. It’s great alongside garlic bread, homemade focaccia, sauteed zucchini, roasted broccoli, roasted asparagus, a green bean casserole with frozen green beans, or a green salad with red wine vinegar salad dressing.
Preparation and Storage Tips
- Make Ahead: Baked pasta dishes are so convenient! Assemble the casserole up to 2 days in advance. Keep it covered in the refrigerator. When ready to bake, allow the dish to sit on the counter and come to room temperature for at least 30-60 minutes before baking according to the recipe instructions. If the dish is cold when it goes into the oven, you will likely need to add some extra baking time. Alternatively, you can boil, drain, and cool the pasta, store it in an airtight container in the fridge for up to 3-4 days, and then just assemble the casserole right before baking.
- How to Store: Leftover baked rigatoni will keep in the refrigerator for 3-4 days. I do not recommend freezing this particular casserole, since the sour cream-based sauce may separate or “break” when thawed from the freezer, giving the dish an undesirable texture and appearance.
- How to Reheat: Cover and reheat leftovers in a 350°F oven for 25-30 minutes, or until warmed through. You can also reheat individual portions in a microwave for 1-2 minutes on high power.

The Best Baked Rigatoni Recipe Variations
- Add meat to the casserole for some additional protein, such as Italian sausage, ground beef, or ground turkey that you cook and crumble separately in a skillet. You can also use your favorite spaghetti meat sauce instead of a jar of marinara.
- For an alternative to sour cream, try crème fraîche, dollops of ricotta cheese, or a homemade bechamel sauce.
- Don’t have rigatoni pasta on hand? Substitute with ziti or penne pasta.
- Add baby spinach to the sauce. It will wilt easily in the hot oven. You can also sneak extra veggies into the dish by stirring in frozen peas, steamed broccoli, or parboiled green beans.
- Saute diced onion and/or mushrooms in butter or olive oil in a skillet over medium-high heat to add to the casserole, or add a dash of onion powder for a little flavor boost.
- Cooking for a smaller family? Cut the ingredients in half and bake the rigatoni in an 8-inch square dish.
