The Thanksgiving table is where tradition and innovation converge, and few dishes capture that spirit quite like cacio e pepe Brussels sprouts. This easy yet show-stopping side dish takes a humble vegetable and elevates it with the iconic flavors of Rome—cheese and freshly cracked black pepper. The result is crispy, golden sprouts enveloped in a melty, spicy, cheesy embrace that will have even Brussels sprouts skeptics coming back for seconds.

Why You’ll Love Cacio e Pepe Brussels Sprouts

  • Flavor Upgrade: Classic roasted Brussels sprouts get an irresistible kick from savory cheese and a peppery edge.
  • Crowd Pleaser: Their bold flavor and satisfying texture win over guests of all ages, even self-proclaimed sprout haters.
  • Simple to Prepare: Just a handful of ingredients and easy roasting instructions make this a practical addition to any meal.
  • Holiday-Ready: The dish’s festive look and gourmet vibe fit perfectly on Thanksgiving or any special occasion table.

What Is Cacio e Pepe?

At its heart, cacio e pepe is the Roman answer to mac and cheese. The phrase means “cheese and pepper” in Italian, referencing a simple sauce made by emulsifying starchy pasta water, grated cheese (usually Pecorino Romano), and plenty of black pepper. Together, they cling to noodles for a dish prized for its rustic, punchy flavor and creamy, peppery sauce.

When reimagined with Brussels sprouts, the dish swaps the pasta for beautifully roasted or pan-crisped sprouts while preserving all that distinctive cheesy-peppery goodness.

Ingredients: The Essentials For Cacio e Pepe Brussels Sprouts

IngredientPurpose
Brussels SproutsMain vegetable, roasted for crispiness
Olive Oil or ButterAdds richness; helps sprouts brown
Kosher SaltBalances and enhances flavor
Freshly Cracked Black PepperEssential for the dish’s signature bite
Pecorino Romano and/or Parmesan CheeseMakes the dish cheesy and nutty
(Optional) Lemon Zest, NutsAdd brightness, texture, and crunch

The ingredient list is reassuringly short. Freshly cracked black pepper makes a difference, imparting aromatic oils, while a blend of Pecorino Romano (for saltiness and sharpness) and Parmesan (for nutty richness) gives depth. Some cooks add finishing touches like lemon zest or toasted nuts for a twist.

How to Prepare Cacio e Pepe Brussels Sprouts

This dish is made either in the oven or with an air fryer. Below is the classic oven method, suited for any home cook.

Step-by-Step Instructions

  1. Prep Your Brussels Sprouts:
    • Trim the ends and remove any outer leaves that are yellowed or damaged.
    • Slice each sprout in half lengthwise for optimal roasting and crisping.
    • Wash and dry the sprouts thoroughly—drying ensures a crispy finish.
  2. Toss and Season:
    • In a large bowl, toss sprouts with olive oil or melted butter until evenly coated.
    • Sprinkle generously with kosher salt and plenty of black pepper.
  3. Roast for Perfection:
    • Spread Brussels sprouts in a single layer, cut-side down, on a parchment- or foil-lined baking sheet.
    • Roast at 425°F (218°C) for about 20–25 minutes, until crisp and deeply golden on the underside and just tender inside.
  4. Cheese It Up:
    • Toss the hot sprouts with a generous mix of grated Pecorino Romano and Parmesan. The residual heat will help the cheese melt slightly and cling to every sprout.
    • Finish with a final shower of freshly cracked black pepper.
  5. Serve Immediately: Pile onto a platter and serve warm for best flavor and texture.

Ingredient Variations & Substitutions

  • Cheese: Substitute all Parmesan or all Pecorino if needed. Pecorino Romano delivers more authentic, sharp, salty flavor, while Parmesan offers mild, nutty notes.
  • Fat: Use avocado oil for a neutral taste, or browned butter for extra depth.
  • Herbs & Citrus: Lemon zest or a squeeze of juice can brighten the dish, especially if you’re serving rich mains.
  • Nuts: Sprinkle toasted hazelnuts or pecans for texture and aroma.
  • Pasta Fusion: Combine roasted cacio e pepe Brussels sprouts with cooked pasta and extra cheese for a main course twist.

Tips for Crisp, Golden Brussels Sprouts

  • Don’t Crowd the Pan: Give each sprout room by spreading them in a single layer; crowded sprouts steam and turn mushy instead of crisp.
  • Cut-Side Down: Arrange sprouts cut-side down so they caramelize for ultimate crunch.
  • High Heat: Roast at 425°F (218°C) or higher to achieve deeply browned, crispy edges.
  • Finish With Cheese: Toss the sprouts with cheese just after roasting, allowing it to melt but not burn.
  • Freshly Cracked Black Pepper: The flavor and aroma are far superior to pre-ground pepper—don’t skimp!

Make-Ahead & Serving Suggestions

  • Prep Ahead: Trim and halve sprouts a day in advance; store in an airtight container in the fridge.
  • Roast Just Before Serving: For maximum crispness, roast sprouts right before your meal.
  • Large Crowd: Double or triple the recipe on multiple baking sheets without overcrowding.
  • Pairing: These sprouts are perfect next to turkey, roast chicken, ham, or as part of a vegetarian feast.

Nutritional Perks

  • Low-Carb & Gluten-Free: No pasta or bread means this dish fits many dietary preferences.
  • Loaded With Fiber: Brussels sprouts offer gut-healthy fiber and essential micronutrients.
  • Rich in Antioxidants: Regular sprouts consumption supplies immune-boosting vitamin C, K, and folate.
  • Protein-Packed Cheese: Pecorino and Parmesan add meaningful protein and calcium.

Frequently Asked Questions (FAQs)

Q: Can I make cacio e pepe Brussels sprouts in advance?

A: You can prep the Brussels sprouts ahead by trimming and halving them. However, for the crispiest results, roast and add cheese just before serving.

Q: What can I use instead of Pecorino Romano cheese?

A: Parmesan cheese is a great substitute and provides a similar, though milder, flavor. For authenticity and sharpness, try to use at least a mix of both cheeses.

Q: Are cacio e pepe Brussels sprouts healthy?

A: Yes! They are high in vitamins, fiber, and antioxidants, and are naturally low in carbs and gluten-free. Cheese adds protein and flavor but should be enjoyed in moderation for those watching fat or salt intake.

Q: Can I use an air fryer instead of the oven?

A: Absolutely! Air frying gives excellent crispness; just reduce cook time and shake the basket for even browning.

Q: Is this dish vegan or dairy-free?

A: As written, the dish contains cheese and sometimes butter, but you can use vegan cheese alternatives and olive oil to suit dairy-free or plant-based diets.
