Equipment Needed

The beauty of this dish is its minimal equipment requirement, making it accessible even for those with a basic kitchen setup.

• Baking sheet (optional, but helpful for roasting vegetables if not roasting directly in the baking dish)
• Colander
• Tongs or large spoon for stirring

Instructions

The method for this Rigatoni al Forno is designed for efficiency without sacrificing flavor. Roasting the vegetables directly in the baking dish infuses the oil with their essence, creating a flavorful base before the pasta even joins the party.

1. Preheat the Oven and Begin Roasting the Onions: Begin by preheating your oven to 375°F (190°C). While the oven heats, place your 9×13 inch glass baking dish on your stovetop over medium heat (if it’s stovetop safe) or carefully place it in the preheated oven. Pour the 3 tablespoons of olive oil into the baking dish. Add the 3 cups of chopped onions, breaking up any large chunks, and stir to coat them thoroughly in the olive oil. Place the uncovered baking dish back into the oven. Roast the onions for 5 minutes.
2. Boil the Pasta: As the onions begin their roast, place a large pot of generously salted water on your stovetop over high heat and bring it to a rolling boil. Once boiling, add the 3/4 lb of rigatoni pasta to the pot.
3. Add Asparagus and Continue Roasting: After the onions have roasted for their initial 5 minutes, carefully remove the baking dish from the oven. Add the 1 lb of asparagus, cut into 2-inch pieces, to the baking dish with the onions. Stir everything together to ensure the asparagus is also coated in the flavorful olive oil. Sprinkle 1/2 teaspoon of salt evenly over the vegetables. Spread the vegetables in a single layer within the baking dish. Return the baking dish to the oven and roast for an additional 5 minutes.
4. Drain Pasta and Combine with Vegetables: While the vegetables continue to roast, drain the rigatoni pasta once it reaches the al dente stage. It should still have a slight bite to it, as it will continue to cook in the oven.
5. Assemble the Rigatoni Al Forno: Remove the baking dish from the oven again. Stir the drained rigatoni pasta directly into the roasted vegetables. Add the 4 tablespoons of balsamic vinegar, a generous amount of freshly ground black pepper, and the 1/3 cup of grated Parmesan cheese. Mix everything together thoroughly to ensure the pasta and vegetables are well combined and coated in the balsamic vinegar and cheese.
6. Top and Bake: Evenly sprinkle the 1/2 cup of breadcrumbs over the top of the pasta and vegetable mixture. Cover the baking dish tightly with aluminum foil. Return the covered dish to the 375°F (190°C) oven.
7. Bake Until Golden and Crisp: Bake for 10 to 15 minutes, or until the breadcrumbs are golden brown and crisp, and the pasta is heated through.
8. Serve: Serve the Rigatoni al Forno hot, with a cruet of extra balsamic vinegar on the side for those who wish to add an extra tangy flourish.

Expert Tips & Tricks

• Onion Power: Don’t shy away from the amount of onion; roasting it caramelizes its natural sugars, adding a wonderful depth of sweetness that forms the backbone of this dish. Cutting them in large chunks ensures they don’t disintegrate during roasting.
• Pasta Precision: Cooking the pasta just a minute or two shy of al dente is crucial. It needs to have a slight chew because it will absorb some of the residual moisture and continue to cook in the oven, preventing it from becoming mushy.
• Balsamic Balance: The balsamic vinegar is key to the dish’s brightness. Use a good quality balsamic for the best flavor. The extra for passing allows diners to customize the tanginess to their preference.
• Breadcrumb Browning: For an extra crispy topping, you can toss the breadcrumbs with a tiny drizzle of olive oil before sprinkling them on. If they aren’t browning as much as you’d like in the allotted time, you can remove the foil for the last 5 minutes of baking.
• Vegetable Versatility: While asparagus is fantastic here, feel free to experiment with other quick-roasting vegetables like broccoli florets, bell pepper strips, or cherry tomatoes in place of or in addition to the asparagus. Adjust roasting times accordingly.

Serving & Storage Suggestions

This Rigatoni al Forno is a complete meal on its own, best served hot straight from the oven to enjoy the crisp topping and perfectly tender pasta. A simple side salad with a light vinaigrette would be a lovely accompaniment.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a covered oven-safe dish at 350°F (175°C) until heated through, or microwave for a quicker option, though the breadcrumb topping may lose some of its crispness.

Variations & Substitutions

While this recipe is designed for simplicity, it’s also a fantastic canvas for creativity.

• Add Protein: For a heartier meal, consider adding cooked Italian sausage (removed from casings and crumbled, then roasted with the onions), grilled chicken, or even chickpeas for a vegetarian protein boost.
• Cheese Exploration: While Parmesan is traditional, a sprinkle of Pecorino Romano or a sharp white cheddar could offer a different flavor profile. For a richer dish, a small amount of mozzarella or provolone could be stirred in with the pasta and vegetables before topping with breadcrumbs.
• Herbaceous Notes: Incorporate fresh herbs like chopped parsley, basil, or a pinch of dried oregano with the pasta and vegetables for added aromatic complexity.

FAQs

Q: Can I make this dish ahead of time?
A: You can roast the vegetables and cook the pasta a day in advance. Store them separately in the refrigerator. When ready to bake, combine them in the baking dish with the other ingredients and proceed with the baking instructions, adding a few extra minutes if needed to heat through.

Q: My rigatoni seems a bit dry after baking. What can I do?
A: Ensure you are using a good quality balsamic vinegar and mixing it thoroughly with the pasta and vegetables. You can also add an extra tablespoon or two of olive oil or a splash of vegetable broth when combining the pasta and vegetables if you prefer a saucier dish.

Q: Is it essential to roast the vegetables in the baking dish?
A: Roasting the vegetables directly in the baking dish infuses the olive oil with their flavors, which then seasons the pasta. While you could roast them on a separate baking sheet, the results won’t be quite the same in terms of integrated flavor.

Q: What kind of breadcrumbs work best?
A: Panko breadcrumbs are excellent for achieving a super crispy topping, but regular dried breadcrumbs will also work well. Homemade breadcrumbs, made from slightly stale bread, are also a fantastic option.

Q: Can I make this recipe gluten-free?
A: Yes! Simply substitute the rigatoni pasta with your favorite gluten-free pasta. Ensure your breadcrumbs are also gluten-free, or omit them altogether.
