A bright and flavorful Lemon Parmesan Brussels Sprout Pasta combining tender spaghetti with caramelized Brussels sprouts, shallots, and a zesty lemon sauce, finished with Parmesan cheese for a perfect weeknight meal.

  • Total Time: 25 minutes
  • Yield: 4 servings

Ingredients

Pasta

  • 8 ounces spaghetti, or pasta of choice

Vegetables & Aromatics

  • 1 pound Brussels sprouts, thinly sliced (or 1 bag shredded Brussels sprouts)
  • 1 cup thinly sliced shallot, or red onion
  • 3 cloves garlic, minced

Seasonings & Other

  • 4 Tablespoons extra virgin olive oil, divided
  • ¾ teaspoon kosher salt, plus more to taste
  • ½ teaspoon ground black pepper, plus more to taste
  • 2 teaspoons fresh lemon zest
  • ¼ cup fresh lemon juice
  • ⅓ cup grated parmesan cheese, plus more for garnish

Instructions

  1. Cook Pasta: Boil a large pot of salted water. Cook the spaghetti 1 minute less than the package instructions. Drain pasta, reserving 1 cup of the pasta cooking water for later use.
  2. Sauté Vegetables: Heat 3 tablespoons of olive oil in a large skillet over medium-high heat. Add the thinly sliced Brussels sprouts and shallots or red onion. Cook, stirring occasionally, until the vegetables start to brown around the edges, about 5 minutes.
  3. Add Seasonings and Cook: Reduce heat to medium. Add kosher salt, ground black pepper, minced garlic, and lemon zest to the skillet. Cook until the garlic becomes fragrant and the vegetables turn tender, about 2 to 3 minutes.
  4. Create Sauce and Combine: Stir in the fresh lemon juice and ½ cup of the reserved pasta water. Add the cooked spaghetti and drizzle with the remaining 1 tablespoon of olive oil. Toss everything together and cook for another minute to allow the sauce to coat the pasta evenly.
  5. Finish with Parmesan: Turn off the heat. Stir in the grated Parmesan cheese. If the pasta looks too dry, add a splash or two more of the reserved pasta water. Taste and adjust seasoning with additional salt and pepper as needed.
  6. Serve: Serve the pasta on a platter or individual plates. Garnish with a drizzle of extra virgin olive oil, a few grinds of black pepper, and extra grated Parmesan cheese.

Notes

  • This dish is best served immediately after preparation. For convenience, you can cook and sauté the Brussels sprouts mixture up to a day ahead and reheat gently before adding pasta.
  • To keep it dairy-free, omit the Parmesan cheese and adjust seasoning accordingly with more salt and pepper.
  • For extra flavor and texture, consider topping with toasted chopped walnuts or almonds, or sprinkle garlic breadcrumbs on top.
