Lemon Parmesan Brussels Sprout Pasta Recipe
Introduction
This Lemon Parmesan Brussels Sprout Pasta is a bright and flavorful dish that combines tender Brussels sprouts with zesty lemon and nutty Parmesan. It’s a simple yet elegant meal perfect for a quick weeknight dinner or a light lunch.

Ingredients
- 8 ounces spaghetti, or pasta of choice
- 4 tablespoons extra virgin olive oil, divided
- 1 pound Brussels sprouts, thinly sliced (or 1 bag shredded Brussels sprouts)
- 1 cup thinly sliced shallot, or red onion
- ¾ teaspoon kosher salt, plus more to taste
- ½ teaspoon ground black pepper, plus more to taste
- 3 cloves garlic, minced
- 2 teaspoons fresh lemon zest
- ¼ cup fresh lemon juice
- ⅓ cup grated Parmesan cheese, plus more for garnish
Instructions
- Step 1: Boil a large pot of salted water. Cook the spaghetti 1 minute less than the package instructions. Drain the pasta, reserving 1 cup of the pasta cooking water.
- Step 2: Heat 3 tablespoons of olive oil in a large skillet over medium-high heat. Add the sliced Brussels sprouts and shallot or red onion. Cook, stirring occasionally, until the vegetables start to brown around the edges, about 5 minutes.
- Step 3: Reduce the heat to medium and add the salt, black pepper, garlic, and lemon zest. Cook until the garlic is fragrant and the vegetables are tender, about 2 to 3 minutes.
- Step 4: Stir in the lemon juice and ½ cup of the reserved pasta cooking water. Add the spaghetti and drizzle with the remaining 1 tablespoon of olive oil. Toss the pasta with the vegetables and cook for another minute to let the sauce coat the pasta.
- Step 5: Turn off the heat and stir in the grated Parmesan cheese. If the sauce seems too dry, add a splash or two of the reserved pasta water. Taste and adjust seasoning with more salt and pepper if needed.
- Step 6: Serve the pasta on a platter or individual plates. Top with a drizzle of extra virgin olive oil, a few grinds of black pepper, and additional grated Parmesan cheese if desired.
Tips & Variations
- Prepare the Brussels sprouts and shallots a day ahead and reheat before mixing with the pasta for a quick meal.
- Use shredded Brussels sprouts for a quicker sauté time and a slightly different texture.
- Add toasted pine nuts or walnuts for extra crunch and flavor.
- Swap spaghetti for other pasta shapes like fettuccine or penne to change up the presentation.
Storage
Store leftover pasta in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over medium-low heat, adding a splash of water or olive oil to loosen the sauce. For best flavor and texture, enjoy the dish fresh when possible.
