Pasta with Crispy Brussels Sprouts and Brown Butter

By BrusselsSprouts.org


The Case for Brussels Sprouts in Pasta

Pasta with vegetables usually falls into one of two categories: virtuous but bland (steamed broccoli tossed with penne) or so loaded with cream and cheese that the vegetables are an afterthought. This recipe is neither.

The idea is simple. Shred Brussels sprouts thin, sear them hard in a skillet until they’re crispy and caramelized, then toss everything with brown butter, garlic, lemon, and Parmesan. The brown butter provides a nutty richness that coats every strand of pasta. The crispy sprout shreds add texture and a savory depth that holds its own against the fat and cheese. A hit of lemon keeps everything bright.

It’s the kind of dish that tastes like it took real effort but actually comes together in about 25 minutes, most of it hands-off while the pasta water boils. Restaurant-quality weeknight dinner. No reservations required.

The Recipe

Ingredients

  • 1 pound dried pasta (rigatoni, penne, or casarecce)
  • 1 pound Brussels sprouts, trimmed and thinly shredded
  • 6 tablespoons unsalted butter
  • 3 cloves garlic, thinly sliced
  • 1/2 teaspoon red pepper flakes
  • 1/2 cup grated Parmesan cheese, plus more for serving
  • 2 tablespoons lemon juice (about 1 lemon)
  • 1 teaspoon lemon zest
  • Kosher salt and black pepper
  • 1 cup reserved pasta water

Choosing the Pasta Shape

Short, ridged pasta works best here. Rigatoni, penne rigate, and casarecce all have grooves and cavities that catch the brown butter sauce and trap small pieces of crispy sprout. Smooth, long noodles like spaghetti let the sauce slide off — you end up with a puddle of butter at the bottom of the bowl and dry pasta on top.

If you only have spaghetti, it still works. Just toss more aggressively and use a bit extra pasta water to help the sauce cling.

Instructions

1. Bring a large pot of salted water to a boil.

Use at least 4 quarts of water. Salt it generously — it should taste like mild seawater. This is your only chance to season the pasta itself, and unseasoned pasta tastes flat no matter how good the sauce is.

Start the water first. By the time it boils (8 to 10 minutes), you’ll have the Brussels sprouts cooked and ready to go.

2. Shred the Brussels sprouts.

Trim the stem ends and halve each sprout through the core. Place each half flat-side down and slice crosswise into thin shreds, about 1/8 inch thick. You’re going for something that looks like coleslaw — thin ribbons that will crisp up quickly in hot fat. If you’ve made our shaved Brussels sprout salad, it’s the same prep technique.

A food processor with a slicing disc speeds this up significantly if you’re working with a full pound.

3. Crisp the Brussels sprouts.

Heat 2 tablespoons of butter in a large skillet (12-inch) over medium-high heat. When the butter melts and the foaming subsides, add the shredded sprouts. Spread them in an even layer.

Here’s the key: don’t touch them for 2 to 3 minutes. Let the bottom layer make full contact with the hot pan and develop color. Then stir, spread them out again, and repeat. Cook for a total of 6 to 8 minutes, until the sprouts are a mix of tender pieces and crispy, dark-edged shreds.

Season with 1/4 teaspoon salt and a few grinds of pepper. Transfer to a bowl and set aside.

4. Brown the butter.

Wipe out the skillet if there are any burnt bits. Add the remaining 4 tablespoons of butter over medium heat.

Watch it carefully. The butter will melt, then foam, then the foam will subside. At that point, the milk solids at the bottom of the pan start to toast. The butter will go from yellow to golden to a deep amber color, and the kitchen will smell like toasted nuts. This takes 3 to 5 minutes.

The window between “perfectly browned” and “burnt” is about 30 seconds. Stay at the stove, swirl the pan occasionally, and the moment it smells nutty and looks amber, pull it off the heat.

Add the sliced garlic and red pepper flakes to the hot brown butter. They’ll sizzle and cook in the residual heat. Stir for 30 seconds — the garlic should turn pale gold, not brown.

5. Cook the pasta.

While the sprouts were cooking, your water should have come to a boil. Add the pasta and cook according to package directions, minus 1 minute. You want it just shy of al dente because it’ll finish cooking in the sauce.

Before draining, scoop out 1 cup of pasta water. This starchy liquid is the secret to a cohesive sauce — it emulsifies with the butter and creates a silky coating instead of a greasy one.

6. Bring it all together.

Return the skillet with the brown butter to medium heat. Add the drained pasta, the crispy Brussels sprouts, and about 1/2 cup of the reserved pasta water. Toss vigorously for 1 to 2 minutes. The pasta water and butter will combine into a glossy sauce that clings to every piece.

Add the Parmesan, lemon juice, and lemon zest. Toss again. If the pasta looks dry or clumpy, add more pasta water a couple tablespoons at a time until the sauce is loose and silky.

Taste for salt. Between the pasta water, the Parmesan, and the seasoning on the sprouts, you may not need more. But if it tastes flat, a pinch of salt will sharpen everything.

7. Serve immediately.

Divide among bowls. Top with additional Parmesan and a few grinds of black pepper. Eat while the sprouts are still crispy — they soften as they sit.

Variations

Pancetta and Brussels Sprouts Pasta

Before crisping the sprouts, cook 4 ounces of diced pancetta in the skillet over medium heat until the fat renders and the pieces are crispy (about 5 minutes). Remove the pancetta, use the rendered fat plus 1 tablespoon butter to crisp the sprouts, and fold everything together at the end. The salty, porky fat takes this from great to extraordinary.

Creamy Brown Butter Version

After adding the pasta water in step 6, stir in 1/3 cup heavy cream. The cream and brown butter together create a sauce that’s richer and more decadent — closer to an alfredo, but with the toasty depth of browned milk solids. Best for a weekend dinner when you’re not counting anything.

Vegan Adaptation

Replace butter with olive oil (you won’t get brown butter flavor, but high-quality olive oil brings its own fruitiness). Skip the Parmesan or use nutritional yeast. Add 2 tablespoons toasted pine nuts or walnuts for the nutty element the brown butter would have provided.

Why Brown Butter Matters

You could make this with regular melted butter and it would still be decent. But brown butter is a different ingredient entirely.

When you heat butter past its melting point, the water evaporates and the milk solids begin to toast. This Maillard reaction — the same one that makes roasted Brussels sprouts so good — produces hundreds of new flavor compounds. The result tastes deeper, nuttier, and more complex than plain butter. It’s concentrated flavor.

In this pasta, the brown butter does double duty. It provides the primary fat for the sauce, and it adds a toasted, almost hazelnut-like flavor that ties together the caramelized sprouts, the sharp Parmesan, and the bright lemon. Every component reinforces the others.

Common Mistakes

Burning the brown butter. The difference between browned and burnt is a matter of seconds. Use medium heat, not high. Swirl the pan. Pull it off the heat the instant it smells nutty and looks amber. If you see black flecks and smell something acrid, start over — there’s no saving burnt butter.

Overcooking the sprouts. You want a mix of textures: some pieces tender, some pieces crispy and almost chip-like. If every shred is soft and olive-drab, you cooked them too long or at too low a heat. High heat, minimal stirring, and pulling them out while some pieces still have bite.

Skipping the pasta water. Without starchy pasta water, you don’t have a sauce — you have pasta with butter pooling at the bottom. The starch emulsifies with the fat and creates a coating. This is the single most common mistake in butter-based pasta dishes.

Using pre-shredded sprouts. Bags of pre-shredded Brussels sprouts from the grocery store are convenient, but they’re often cut too thick and dried out from sitting in packaging. Fresh sprouts shredded right before cooking crisp better and taste sweeter. It takes 5 minutes with a knife.

Make It a Complete Meal

On its own, this pasta is satisfying but protein-light. A few additions round it out:

  • Chicken: Slice a grilled or pan-seared chicken breast and lay it on top.
  • Sausage: Brown sliced Italian sausage with the Brussels sprouts.
  • White beans: Toss in a drained can of cannellini beans with the pasta water. They absorb the brown butter sauce and add creaminess plus protein.
  • A fried egg on top: The runny yolk enriches the sauce further. Not traditional, but extremely good.

This is a dish worth having in regular rotation. Minimal ingredients, fast execution, and a flavor payoff that’s wildly disproportionate to the effort involved. Brussels sprouts and brown butter were made for each other.
