Ingredients

For this brunch‑worthy pasta I rely on the freshest seasonal vegetables and a classic basil pesto that’s made from scratch. The grilled veggies bring a smoky depth, while the pesto supplies a buttery, garlicky backbone. A touch of lemon zest brightens the finish, and toasted pine nuts add a satisfying crunch that elevates the whole dish.

Main Ingredients

  • 12 oz (340 g) penne pasta
  • 1 medium zucchini, sliced ½‑inch thick
  • 1 medium yellow squash, sliced ½‑inch thick
  • 1 red bell pepper, cut into 1‑inch strips
  • ½ red onion, cut into wedges
  • 1 cup cherry tomatoes, halved

Pesto Sauce

  • 2 cups fresh basil leaves, packed
  • ¼ cup pine nuts (plus extra for topping)
  • ¼ cup grated Parmesan cheese
  • 2 garlic cloves, minced
  • ½ cup extra‑virgin olive oil
  • ½ teaspoon sea salt
  • ¼ teaspoon freshly ground black pepper

Seasonings & Garnish

  • 2 tablespoons olive oil (for grilling)
  • ½ teaspoon smoked paprika
  • Zest of 1 lemon
  • Freshly grated Parmesan, for serving

The combination of these ingredients creates a harmonious balance of smoky, herbaceous, and bright flavors. Grilled zucchini, squash, and bell pepper develop caramelized edges that pair perfectly with the creamy basil pesto. The lemon zest lifts the richness, while the toasted pine nuts add texture. Together they form a brunch‑worthy pasta that feels both indulgent and nourishing.

Step-by-Step Instructions

Grilling the Vegetables

Preheat a grill pan or outdoor grill to medium‑high heat (about 400°F/200°C). Toss the zucchini, yellow squash, bell pepper, and red onion wedges with 2 tablespoons olive oil, ½ teaspoon smoked paprika, and a pinch of salt. Place them on the grill in a single layer, cooking 3–4 minutes per side until grill marks appear and the vegetables are just tender. Transfer to a plate and set aside; the residual heat continues to soften them slightly.

Making the Basil Pesto

While the veggies grill, combine 2 cups fresh basil leaves, ¼ cup pine nuts, ¼ cup grated Parmesan, and 2 minced garlic cloves in a food processor. Pulse until coarsely chopped, then drizzle in ½ cup extra‑virgin olive oil while the processor runs, stopping to scrape the sides as needed. Season with ½ teaspoon sea salt and ¼ teaspoon black pepper. The pesto should be smooth yet retain a slight texture; set aside.

Cooking the Pasta & Combining

  1. Boil the Pasta. Bring a large pot of salted water to a rolling boil. Add the 12 oz penne and cook according to package directions until al dente, usually 10–11 minutes. Reserve ½ cup of pasta water before draining.
  2. Combine Ingredients. Return the drained pasta to the pot over low heat. Add the grilled vegetables, halved cherry tomatoes, and the freshly made pesto. Toss gently, adding reserved pasta water a tablespoon at a time until the sauce coats each piece evenly and glistens.
  3. Finish with Brightness. Stir in the zest of 1 lemon and taste for seasoning. If the pesto feels thick, incorporate a little more pasta water. Let everything warm together for another 2 minutes so flavors meld.
  4. Plate & Garnish. Divide the pasta among serving bowls. Sprinkle with toasted pine nuts, an extra drizzle of olive oil, and a generous shaving of Parmesan. Serve immediately while warm and aromatic.

Tips & Tricks

Perfecting the Recipe

Pre‑heat the Grill Properly. Allow the grill to reach full temperature before adding vegetables; this ensures quick searing and prevents soggy specks.

Dry Vegetables Thoroughly. Pat sliced veggies dry with a towel before oiling; excess moisture creates steam and hinders grill marks.

Reserve Pasta Water. The starchy water is the secret to a glossy, emulsified pesto sauce that clings to each penne.

Flavor Enhancements

Add a splash of white wine vinegar to the pesto for a subtle tang, or toss in a pinch of red‑pepper flakes for gentle heat. For extra richness, finish the dish with a tablespoon of butter swirled into the sauce just before plating.

Common Mistakes to Avoid

Avoid over‑cooking the vegetables; they should retain a slight bite to contrast the pasta. Also, don’t blend the pesto too long—over‑processing can turn the bright basil into a muted paste and cause the oil to separate.

Pro Tips

Toast Pine Nuts First. Lightly toast them in a dry skillet until golden; this unlocks a deeper nutty flavor that shines in the pesto and as a garnish.

Use a Food Mill for Pesto. If you own a food mill, it produces a silkier texture than a processor while preserving the basil’s bright green color.

Season in Layers. Lightly salt the veggies before grilling, then adjust the final seasoning after mixing with pesto; this builds depth without over‑salting.

Variations

Ingredient Swaps

Replace penne with farfalle or fusilli for a different bite. Swap zucchini for eggplant or asparagus for a heartier texture. If you prefer a milder pesto, use spinach or arugula in place of half the basil. For a nut‑free version, substitute toasted sunflower seeds for pine nuts.

Dietary Adjustments

To keep it gluten‑free, use brown rice pasta or chickpea pasta. Make the dish vegan by omitting Parmesan and using nutritional yeast, plus a drizzle of vegan “Parmesan.” For a low‑carb brunch, serve the pesto over spiralized zucchini noodles instead of pasta.

Serving Suggestions

Pair with a crisp citrus‑infused mixed green salad or a side of roasted baby potatoes. A light glass of chilled Prosecco or a freshly squeezed orange‑mint juice complements the herbaceous flavors beautifully.

Storage Info

Leftover Storage

Allow the pasta to cool to room temperature, then transfer to an airtight container. Store in the refrigerator for up to 3 days. For longer keeping, portion into freezer‑safe bags, squeeze out excess air, and freeze for up to 2 months. The pesto may darken slightly, but flavor remains intact.

Reheating Instructions

Reheat gently on the stovetop over low heat, adding a splash of broth or water to revive the sauce. Alternatively, microwave in a covered bowl on medium power for 1‑2 minutes, stirring halfway. Finish with a drizzle of fresh olive oil or a pinch of lemon zest to brighten the reheated dish.

Frequently Asked Questions

Absolutely. You can grill the vegetables and prepare the pesto up to 24 hours in advance. Store each component in separate airtight containers in the fridge. When you’re ready to serve, simply cook the pasta, toss everything together, and garnish. This makes weekend brunches a breeze.

You can, but thaw them completely and pat dry before grilling. Frozen veggies release extra moisture, which can prevent proper browning. If you’re short on time, a quick microwave thaw followed by a paper‑towel squeeze works well.

Light sides work best. A simple arugula salad dressed with lemon vinaigrette adds peppery contrast. Crusty sourdough or garlic‑infused focaccia is perfect for mopping up extra pesto. Fresh fruit salad or a chilled citrus spritzer rounds out a brunch spread nicely.

Omit the Parmesan and replace it with ¼ cup nutritional yeast for a cheesy note. Use a vegan pesto (omit cheese, add extra nuts or seeds) and choose a pasta made without egg. The rest of the recipe stays identical, delivering the same bright flavors.

This Grilled Veggie Pesto Pasta brings together smoky summer vegetables, a silky basil pesto, and al dente pasta for a brunch that feels both indulgent and wholesome.
