Lemony Broiled Cauliflower Pasta: An Effortlessly Delicious Vegetarian Weeknight Meal
This simple broiled cauliflower pasta dish perfectly marries enticing flavors and textures, creating a satisfying and wholesome vegetarian meal ideal for any busy weeknight. It’s a quick recipe that doesn’t compromise on taste, making it a staple in your culinary repertoire.

My culinary adventures often lead me back to cauliflower, a vegetable whose versatility I find truly boundless. Among the many ways to prepare it, broiling stands out as my absolute favorite. This method caramelizes the florets, bringing out a depth of flavor and a delightful tenderness that roasting simply can’t match. Broiled cauliflower is incredibly adaptable, transforming ordinary dishes into extraordinary ones. Imagine it as a savory topping for creamy homemade hummus or elegant tartines, lending a smoky, nutty essence. It makes a fantastic garnish for hearty soups and vibrant salads, adding both substance and a textural contrast. You can even incorporate it into diverse main courses, from savory fried rice to creamy risotto, enhancing each with its unique character.
However, if I had to choose just one application for broiled cauliflower, it would undoubtedly be pasta. There’s something magical that happens when perfectly broiled cauliflower is tossed with al dente pasta. This particular recipe for Lemony Broiled Cauliflower Pasta exemplifies this culinary synergy. Here, the cauliflower florets are infused with aromatic shallots and pungent garlic as they crisp under the broiler, developing irresistible browned edges and a tender interior. These delectable morsels are then gently folded into a vibrant mix: fresh baby spinach for a nutritious boost, bright lemon zest and juice for a zesty kick, sharp Pecorino Romano cheese for a tangy depth, a pinch of crushed red pepper for a delightful warmth, and finally, crunchy toasted almonds to provide a textural counterpoint. The result is a simple yet profoundly satisfying vegetarian weeknight meal that can easily elevate a casual dinner. It’s also sophisticated enough to serve as a delightful primi piatti for a more elaborate weekend gathering, showcasing complex flavors with minimal effort.

Helpful Tips for Crafting the Best Broiled Cauliflower Pasta
No Rigatoni? No Problem! Short Pasta Alternatives for Your Dish
While rigatoni is a fantastic choice for this broiled cauliflower pasta, its ridged tubes capturing all the flavorful sauce, don’t let its absence deter you. Short pasta varieties generally work best in this dish because their size and shape allow them to intermingle perfectly with the broiled cauliflower florets and tender baby spinach. This creates harmonious, easy-to-eat bites where every component is roughly the same size, ensuring a balanced flavor and texture in each forkful. If rigatoni isn’t in your pantry, feel free to substitute with other popular short pastas such as penne, fusilli, orecchiette, or even farfalle. These shapes will hold up well to the sauce and vegetables. However, I would recommend avoiding extremely small pasta types like macaroni or orzo. The significant difference in size between these tiny pastas and the larger cauliflower florets can make the dish awkward to eat, diminishing the enjoyable experience.
Serving Versatility: Hot or Cold Broiled Cauliflower Pasta Salad
One of the many charms of this straightforward pasta dish is its incredible versatility – it’s equally delightful served hot or as a refreshing cold pasta salad. If your plans include enjoying this broiled cauliflower pasta chilled, perhaps for a picnic, potluck, or meal prep, a small adjustment will ensure its success. It’s crucial to let both the cooked pasta and the broiled cauliflower cool completely to room temperature before incorporating the delicate baby spinach. Adding spinach while the other ingredients are still warm will cause it to wilt prematurely, losing its vibrant green color and crisp texture. By allowing everything to cool, your spinach will remain fresh, giving the dish a beautiful, “salady” appearance and a pleasant crunch. For detailed instructions and further tips on how to expertly transform this warm comforting meal into a bright and tangy cold pasta salad, please refer to the recipe notes provided below.
Elevate Your Meal: Adding Protein to Your Broiled Cauliflower Pasta
This lemony broiled cauliflower pasta shines as a vegetarian main course, rich in flavor and texture. However, for those looking to boost the protein content or simply make it an even heartier, more substantial meal, it’s incredibly adaptable. On days when I have leftover rotisserie chicken, I love to shred it and fold it into the pasta—it adds a savory depth and makes the dish even more fulfilling. But the possibilities don’t stop there! Cooked shrimp or succulent pan-seared salmon would introduce a delightful seafood twist, complementing the lemon and garlic beautifully. Even luxurious lobster meat would be a fantastic addition for a special occasion. For a plant-based protein boost, consider adding canned chickpeas (drained and rinsed), cannellini beans, or even some pan-fried tofu cubes. These additions not only enhance the nutritional profile but also introduce new textures and flavors, making the dish endlessly customizable to your preferences.

Pin Recipe
Lemony Broiled Cauliflower Pasta
Ingredients
- 2 cups cauliflower florets (approximately half a medium-sized head of cauliflower, cut into bite-sized pieces)
- 1 shallot, thinly sliced to caramelize beautifully
- 1 clove garlic, minced or finely grated for maximum flavor infusion
- 1 tbsp extra-virgin olive oil, for roasting and richness
- ½ tsp kosher salt, or high-quality fine sea salt, to taste
- ¼ tsp crushed red pepper, adjust to your preferred spice level
- 6 oz dry rigatoni pasta, or any other short pasta variety such as penne, fusilli, or orecchiette
- ½ lemon, finely grated zest and fresh juice (yielding about 1 tsp / 5 ml zest and 1/4 cup / 60 ml juice, for bright, zesty flavor)
- ½ cup freshly gratedPecorino Romano cheese, for a sharp, salty, and tangy addition
- 2 handfuls fresh baby spinach, for a burst of color and nutrition
- ¼ cup chopped fresh basil, for an aromatic, sweet finish
To serve
- ¼ cup toasted slivered, sliced, or chopped almonds, for a delightful crunch and nutty flavor
- Additional gratedPecorino Romano cheese, for a final flourish
Instructions
-
Begin by preheating your oven to 450°F (230°C). Position an oven rack in the upper third of the oven, but not at the very top setting to prevent burning. Prepare a baking sheet by lining it with aluminum foil, then lightly brush or spray the foil with olive oil to prevent sticking.
-
In a spacious mixing bowl, combine the cauliflower florets, thinly sliced shallots, minced garlic, a tablespoon of olive oil, kosher salt, and crushed red pepper. Toss everything together thoroughly to ensure the cauliflower is evenly coated with the seasonings. Spread this mixture in a single layer over the prepared baking sheet. Broil for 10 minutes, or until the cauliflower florets are beautifully tender with enticing browned and slightly charred spots. Remove the baking sheet from the oven and set the cauliflower aside.
-
While the cauliflower is broiling, bring a large pot of generously salted water to a rolling boil. Add your chosen pasta (rigatoni or another short variety) and cook it for 1 minute less than the package instructions recommend. This will ensure your pasta remains perfectly al dente. Just before you drain the pasta, use a heatproof measuring cup to scoop out about 1/2 cup (125 ml) of the starchy pasta cooking water and set it aside; this will be crucial for creating a silky sauce. Drain the pasta thoroughly.
-
Return the same pot you used for the pasta to medium heat. Add the drained pasta, the reserved pasta cooking water, and the vibrant lemon zest and juice. Toss gently to combine all the elements and bring the mixture to a gentle simmer. Gradually sprinkle in the grated Pecorino Romano cheese, stirring continuously as you add it. This constant stirring will help the cheese melt smoothly and emulsify with the liquid, creating a rich and flavorful sauce that coats every strand of pasta. Finally, fold in the broiled cauliflower, fresh baby spinach, and chopped basil. Continue cooking and stirring for just a minute or two, only until everything is heated through and the baby spinach has softly wilted.
-
SERVING SUGGESTIONS: Serve this delicious broiled cauliflower pasta immediately, piping hot, to enjoy its freshest flavors and textures. For an extra touch of gourmet elegance and flavor, garnish each plate generously with additional freshly grated Pecorino Romano cheese and a sprinkle of toasted almonds. This enhances both the taste and visual appeal of the dish.
-
STORAGE AND REHEATING: This lemony broiled cauliflower pasta is fantastic for meal prep as it stores and reheats beautifully. Allow any leftovers to cool completely before transferring them to an airtight container. Store in the refrigerator for up to 3-4 days. To reheat, simply microwave for approximately 1 to 2 minutes, or until warmed through. Alternatively, for a stovetop reheat, place the pasta in a skillet over medium heat, adding a tablespoon or two of water or vegetable broth to help loosen the sauce and restore its creamy texture.
-
MAKE IT VEGAN: Easily adapt this recipe to be completely vegan without sacrificing flavor. Simply substitute the Pecorino Romano cheese with ¼ cup (15 g) of nutritional yeast. Nutritional yeast provides a similar savory, cheesy depth, making this a delicious plant-based option.
-
HOW TO SERVE AS A COLD PASTA SALAD: For a refreshing take, broil the cauliflower as instructed in step 2. Cook the pasta according to package directions, but skip reserving the pasta water. Once both the cauliflower and pasta are cooked, transfer them to a large mixing bowl and allow them to cool completely to room temperature. This is crucial for preventing the spinach from wilting. Once cooled, drizzle in an extra 2 tablespoons (30 ml) of high-quality extra-virgin olive oil for added richness. Then, mix in the lemon zest and juice, grated Pecorino Romano (or nutritional yeast for a vegan version), fresh baby spinach, and chopped fresh basil. Season generously with freshly ground black pepper and additional salt if needed. Toss everything thoroughly to combine all the vibrant flavors. Serve immediately as a delightful cold pasta salad, or refrigerate in an airtight container for up to 2 days. For the best flavor and texture, I highly recommend allowing the pasta salad to come back to room temperature for at least 1 hour before serving.
