Ingredients

This dish is a testament to the magic that happens when humble vegetables meet pasta and cheese. The key is in the caramelization of the cauliflower and the textural contrast of the crunchy topping.

• 1 pound rigatoni pasta
• 1 medium cauliflower, about 1.5 pounds
• 4 tablespoons olive oil, divided (extra-virgin is preferred)
• Salt and freshly ground black pepper, to taste
• 1 tablespoon capers, roughly chopped
• 3 cloves garlic, minced
• 1/4 teaspoon crushed red pepper flakes (adjust to your heat preference)
• 3 tablespoons fresh sage, roughly chopped, plus a few whole sage leaves for infusing
• 1/2 teaspoon lemon zest
• 6 ounces Fontina cheese, coarsely grated (mozzarella can be substituted, though Fontina offers a nuttier depth)
• 2 ounces Romano cheese, finely grated (or another hard, salty pecorino cheese)
• 1/2 cup breadcrumbs, coarse and dry (panko or homemade breadcrumbs work beautifully)
• 2 tablespoons fresh flat-leaf parsley, chopped, for garnish

Equipment Needed

• Large pot for boiling pasta
• Large skillet
• Baking dish (approximately 9×13 inches or similar capacity)
• Mixing bowls
• Sharp knife and cutting board
• Grater

Instructions

The process is straightforward, focusing on building layers of flavor and texture. Don’t rush the caramelization of the cauliflower; it’s where much of the dish’s depth comes from.

1. Preheat the Oven and Prepare the Cauliflower: Begin by preheating your oven to 400 degrees Fahrenheit (200 degrees Celsius). Prepare the cauliflower by cutting it in half from top to bottom. Carefully remove the tough core and any extraneous leaves. Lay the cauliflower halves cut-side down and slice them crosswise into rough 1/4-inch thick slices. You can then break these slices into smaller, more manageable pieces.

2. Caramelize the Cauliflower: Heat 3 tablespoons of olive oil in a wide skillet over high heat. Add the cauliflower slices and any crumbly pieces. It’s important to add the cauliflower in a single layer for optimal browning. If your skillet isn’t large enough, work in batches to avoid overcrowding, which will steam the cauliflower instead of browning it. Let the cauliflower brown and caramelize for about 2 minutes on one side, then turn the pieces over to brown the other side. Continue cooking for another 2 minutes, or until the cauliflower is easily pierced with a fork. It’s perfectly fine if some pieces don’t brown evenly; the varied caramelization adds complexity. Season generously with salt and pepper as it cooks.

3. Infuse Flavors into the Cauliflower: Once the cauliflower is tender and nicely browned, add the chopped capers, minced garlic, crushed red pepper flakes, the chopped sage, the reserved whole sage leaves, and the lemon zest to the skillet. Stir everything together to coat the cauliflower and allow the aromatics to bloom for about 30 seconds, being careful not to burn the garlic.

4. Combine and Assemble: Transfer the cooked cauliflower mixture to a large mixing bowl. In a separate pot of generously salted boiling water, cook the rigatoni pasta according to package directions until al dente. Drain the pasta well. Add the cooked rigatoni and the coarsely grated Fontina cheese to the bowl with the cauliflower mixture. Toss everything together until the pasta and cauliflower are well combined and the cheese begins to melt and coat the ingredients.

5. Prepare for Baking: Lightly oil a baking dish. Transfer the rigatoni and cauliflower mixture into the prepared baking dish, spreading it evenly. Top the mixture with the finely grated Romano cheese, followed by the breadcrumbs. Drizzle the remaining 1 tablespoon of olive oil evenly over the breadcrumb topping. At this point, the dish may be completed up to several hours in advance and kept at room temperature, covered. This makes it an excellent option for entertaining.

6. Bake the Al Forno: Bake, uncovered, in the preheated 400-degree Fahrenheit oven for 20 to 30 minutes, or until the top is crisp and golden brown. The exact time will depend on your oven and the depth of your baking dish. Keep an eye on it towards the end to ensure the breadcrumbs don’t burn.

7. Garnish and Serve: Once out of the oven, sprinkle generously with freshly chopped flat-leaf parsley before serving.

Expert Tips & Tricks

• Cauliflower Cut Matters: While slicing into rounds is easy, breaking the cauliflower into florets and then rough-chopping them can also work well for browning, especially if you have smaller pieces. Just ensure you still get good surface area contact with the pan.
• Don’t Fear the Brown Bits: The fond that develops in the skillet from browning the cauliflower is pure flavor. Be sure to scrape up any browned bits when you add the aromatics.
• Pasta Water is Gold: Reserve a small amount of the starchy pasta cooking water before draining. If the mixture seems a little dry when you’re tossing it with the cauliflower and cheese, a tablespoon or two of this water can help create a silkier sauce.
• Breadcrumb Texture: For an extra crispy topping, consider toasting your breadcrumbs lightly in a dry skillet before adding them to the dish. This ensures they absorb less oil and get even crunchier in the oven.
• Make-Ahead Magic: As mentioned in the instructions, this dish truly shines as a make-ahead option. Assemble it, cover it, and let it sit at room temperature for a few hours before baking. This allows the flavors to meld beautifully and reduces your active cooking time right before serving.

Serving & Storage Suggestions

This Rigatoni and Cauliflower Al Forno is a hearty, complete meal in itself, but it also pairs wonderfully with a simple green salad dressed with a light vinaigrette. Serve it hot, straight from the oven, allowing the steam to rise and the enticing aroma to fill the room.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm individual portions in the microwave or oven at 350 degrees Fahrenheit (175 degrees Celsius) until heated through. For a crisper topping, you can place it under the broiler for a minute or two, watching carefully to prevent burning. Freezing is not ideal, as the texture of the pasta and cauliflower can become mushy upon thawing.

Variations & Substitutions

• Spice It Up: For a spicier kick, increase the crushed red pepper flakes or add a pinch of cayenne pepper.
• Herb Variations: While sage is traditional and delightful here, consider using thyme or a blend of Italian herbs. A sprinkle of fresh rosemary when caramelizing the cauliflower can also add another dimension.
• Cheese Exploration: Feel free to experiment with other good melting cheeses like Gruyère, Provolone, or even a touch of smoked mozzarella for a different flavor profile.
• Gluten-Free Option: To make this gluten-free, simply use gluten-free rigatoni pasta and gluten-free breadcrumbs. Ensure your cheese is also certified gluten-free.

FAQs

Q: Can I use a different type of pasta?
A: Yes, while rigatoni’s tubes hold sauce and chunks well, other short pasta shapes like penne, ziti, or even farfalle would also work nicely.

Q: My cauliflower didn’t brown well. What did I do wrong?
A: Ensure your skillet is hot enough and that you’re not overcrowding the pan. Browning takes time and heat to develop those sweet, caramelized flavors.

Q: How can I make this dish vegetarian-friendly?
A: The recipe as written is vegetarian. Ensure your breadcrumbs and cheeses do not contain animal rennet if you are seeking strict vegetarian options.

Q: Can I add other vegetables?
A: Absolutely! Broccoli florets or roasted bell peppers could be excellent additions, though they may alter the cooking time slightly.

Q: Is this dish suitable for a crowd?
A: Yes, this recipe is easily scaled up and is a fantastic dish to prepare for gatherings due to its make-ahead potential.
