Crispy Brussel Sprout Hash with Eggs: A Flavorful & Healthy Breakfast Twist
Forget the classic potato breakfast for a moment and welcome a delightful, nutrient-packed alternative to your morning table: Brussel Sprout Hash. This inventive twist on a breakfast staple features finely shredded Brussels sprouts, savory onions, simple yet impactful seasonings, and a touch of fresh herbs. As these tiny green powerhouses sauté in a hot skillet, they transform, caramelizing beautifully and developing a irresistible crispy texture, much like traditional hash browns. Whether you prefer it as a standalone vegetarian dish or topped with perfectly cooked eggs for a complete, satisfying meal, this Brussel Sprout Hash is an excellent choice for a vibrant breakfast or a leisurely brunch.

Often associated with holiday dinners, Brussels sprouts (correctly named Brussels sprouts after the Belgian city where they were first cultivated) enjoy a long season, typically from late August through March. While they might be a familiar sight at your Thanksgiving table, their delicate, slightly bitter flavor, when cooked correctly, makes them an incredibly versatile vegetable. This recipe aims to showcase their potential beyond just a side dish, transforming them into the star of a hearty and wholesome breakfast.
This breakfast hash is infused with an array of simple yet profound flavors that elevate the humble sprout. A base of rich olive oil sets the stage, while a hint of Dijon mustard introduces a bright, tangy note. Crushed fennel seeds add a subtle anise-like warmth, complementing the natural earthiness of the sprouts, and fresh thyme brings a fragrant, lemony aroma. When Brussels sprouts are sautéed or roasted, they undergo a magical transformation, developing a naturally sweet, nutty, and deeply caramelized flavor. And those crispy, slightly charred bits? They are, without a doubt, the best part, adding a textural delight that keeps you coming back for more.
Designed for convenience and maximum flavor, this Brussel sprout hash, much like a good sweet potato hash, is effortlessly made in a single skillet. To keep this recipe accessible to all dietary preferences, I’ve opted for a vegetarian approach, omitting bacon. However, it’s incredibly adaptable if you wish to add meat. This hash serves wonderfully as a robust fall side dish, but I particularly love to crack a few eggs directly into the skillet, letting them cook to perfection, creating a complete and satisfying one-pan meal perfect for any day of the week.
Beyond its delicious taste, Brussels sprout hash offers impressive nutritional benefits. Brussels sprouts are packed with vitamins K and C, fiber, and antioxidants, making this breakfast a fantastic way to kickstart your day with wholesome goodness. It’s a low-carb, high-fiber alternative that satisfies without leaving you feeling heavy, making it an excellent choice for those seeking a healthier breakfast option.
This recipe isn’t just about cooking; it’s about discovering the hidden potential of a vegetable often misunderstood. With minimal ingredients and straightforward steps, you can create a meal that’s both comforting and exciting, challenging preconceived notions about Brussels sprouts and inviting them to become a regular feature in your culinary repertoire. Get ready to fall in love with Brussels sprouts all over again, but this time, for breakfast!

Ingredient Notes & Tips
Understanding each ingredient’s role is key to perfecting your vegetable hash. Below, discover more about the components that make this dish so special.

- Brussel Sprouts: For the best results, seek out whole, firm Brussels sprouts at your local grocery store or farmer’s market. They may be sold individually or still on their stalks; either is fine, though those on the stalk require a bit more preparation. If you’re short on time, pre-shredded (or shaved) Brussels sprouts are a convenient option. Just ensure they look fresh with no yellowing leaves, and use them promptly for optimal flavor and texture.
- Onion: I personally prefer red onion for its vibrant color and slightly milder, sweeter flavor profile that caramelizes beautifully. However, a sweet, white, or yellow onion will also work wonderfully, each adding its own subtle nuance to the hash.
- Dijon Mustard: This ingredient is crucial for adding a touch of brightness and acidity, which helps to cut through the richness and balance the flavors of the caramelized Brussels sprouts. Its subtle tang is a game-changer.
- Fennel Seeds: These aromatic seeds impart a unique, delicate anise-like flavor that pairs exceptionally well with Brussels sprouts. For the most intense aroma and flavor, remember to gently crush them before adding them to the skillet.
- Thyme: Fresh thyme is highly recommended for its earthy and slightly lemony notes, which enhance the overall profile of the hash. If fresh thyme isn’t available, you can substitute with dried thyme, using half the amount as its flavor is more concentrated.
- Olive Oil: Extra-virgin olive oil is my go-to for sautéing the sprouts, providing a fruity depth of flavor. Feel free to use your preferred cooking oil, such as vegetable or canola oil. For an incredibly rich and indulgent hash, consider sautéing the Brussels sprouts in butter.
- Salt and Pepper: Essential for seasoning, these pantry staples are added throughout the cooking process and adjusted at the end to ensure the hash is perfectly seasoned to your taste.
- Eggs: While optional, adding eggs turns this hash into a complete, protein-rich meal. They can be cooked directly into wells created in the hash, fried separately, or even poached to your preference.
How to Perfectly Shred Brussels Sprouts
While pre-shredded Brussels sprouts offer convenience, there’s something undeniably superior about freshly shaved ones. Shredding them yourself allows you to control the texture, leaving some pieces a bit chunkier for an added delightful bite.
You have two main methods for shredding: by hand or using a food processor. I personally prefer the precision and rustic texture achieved by hand-shredding with just a sharp knife and a sturdy cutting board. However, if you’re looking to save time, a food processor can get the job done quickly and efficiently.

First, thoroughly wash your Brussels sprouts and trim off any tough or bruised outer leaves. Then, hold each sprout lengthwise and carefully slice it down the middle, creating two halves. This cut exposes more surface area for even shredding.

Place each half cut-side down on your cutting board. With your sharp knife, begin slicing thinly from the outside edge towards the stem. Aim for uniform strips that will cook evenly and achieve that coveted crispy texture. Repeat with all Brussels sprouts until you have a pile of beautifully shredded greens.
Crafting Your Delicious Brussel Sprout Hash
For a comprehensive step-by-step guide with precise measurements, please refer to the detailed recipe card below. However, here’s a quick visual overview to help you get started on your culinary journey.

Step 1: Sauté the Onions. Begin by heating a tablespoon of olive oil in a large skillet over medium heat. Add your chopped red onions and a pinch of salt. Sauté them gently for about 2-3 minutes until they become soft and translucent, but be careful not to brown them excessively. This slow sauté coaxes out their natural sweetness.

Step 2: Add Brussels Sprouts and Seasonings. Introduce the shredded Brussels sprouts to the skillet along with the remaining olive oil. You might need to add them in batches at first if your skillet is overflowing; they will wilt down quickly. Sauté until they are softened and have reduced in volume. Then, stir in the Dijon mustard, crushed fennel seeds, remaining salt, and freshly ground pepper, ensuring everything is well coated. Continue to sauté, stirring occasionally, until the Brussels sprouts turn a beautiful golden brown and develop deliciously crispy edges, typically 12-14 minutes. Finish by stirring in the fresh thyme.

Step 3: Prepare for Eggs (Optional). If you plan to add eggs, gently push some of the hash to the side to create 3-4 individual wells or spaces in the skillet. This will provide a cozy spot for each egg to cook directly within the hash.

Step 4: Cook the Eggs. Carefully crack one egg into each prepared well. Cover the skillet tightly with a lid and continue to cook over medium heat for an additional 5-6 minutes, or until the egg whites are fully set and the yolks are cooked to your desired consistency (runny, jammy, or firm). This creates a perfectly integrated, one-pan breakfast.
Once the eggs are cooked to your liking, give the hash a final taste for seasoning, adding extra salt and pepper as needed to bring out all the vibrant flavors. Serve immediately and enjoy your perfectly cooked Brussel Sprout Hash!
💡Expert Tip for Crispy Perfection
To achieve that coveted, beautifully browned, and crispy texture on your Brussels sprouts, resist the urge to stir them constantly. Instead, allow them to cook undisturbed in the hot skillet for several minutes at a time before gently tossing. This direct contact with the heat allows the bottoms to caramelize and crisp up faster, building layers of delicious flavor and texture.
Substitutions and Variations to Customize Your Hash
This Brussel sprout hash recipe is truly a blank canvas, inviting you to experiment with various add-ins and seasonings to make it uniquely your own. Don’t hesitate to play around with different flavors and textures!
- Add Savory Meats: For a heartier meal, incorporate your favorite meats. Crispy bacon, rich pancetta, or delicate prosciutto pair exceptionally well with the sweetness of caramelized Brussels sprouts. Alternatively, crumbled sweet or spicy sausage would also make a fantastic and flavorful addition. Cook your chosen meat first, then proceed with the hash, utilizing some of the rendered fat for extra flavor.
- Introduce More Veggies: Elevate this into the ultimate fall breakfast by adding other seasonal vegetables. Chopped sweet potatoes or butternut squash, diced carrots, or even bell peppers would contribute beautiful colors, additional nutrients, and a delightful sweetness. Ensure these denser vegetables are diced finely for even cooking.
- Experiment with Herbs: While fresh thyme offers a classic flavor, feel free to use any combination of fresh or dried herbs you enjoy. Fresh parsley or chives, finely chopped, can add a bright, fresh finish. Rosemary, sage, or even a touch of marjoram could also introduce interesting aromatic notes.
- Boost with Garlic: For an extra layer of savory depth, try adding one or two minced garlic cloves to the skillet after the onions have softened, cooking for just 30 seconds until fragrant before adding the Brussels sprouts. This ensures the garlic flavor is present without overpowering the dish.
- Spice It Up: If you enjoy a bit of heat, easily transform this hash into a spicy delight. A pinch of crushed red pepper flakes or a dash of cayenne pepper added with the other seasonings will give it a pleasant kick. Adjust the amount to your preferred level of spice.
- Cheesy Goodness: A sprinkle of grated cheese can add a wonderful creamy, salty, or tangy dimension. Parmesan cheese offers a nutty and sharp flavor, while crumbled goat cheese or feta could provide a delightful tang. Shredded sharp cheddar or gruyere would also melt beautifully into the hash.
- Sweet & Tangy Drizzles: For a gourmet touch, a drizzle of balsamic glaze (reduced balsamic vinegar) adds a sweet and tangy counterpoint that harmonizes perfectly with the sprouts. Pomegranate molasses offers a similar sweet-tart complexity and a beautiful sheen.
Creative Serving Suggestions
This versatile hash can be enjoyed in many ways, adapting to your meal and preferences. Serve it proudly as a flavorful side dish alongside your favorite brunch items, or elevate it to a complete meal by adding eggs. If you choose to add eggs directly into the hash, remember to toast up some crusty bread or sourdough slices to perfectly sop up that rich, runny yolk. If you prefer your yolks firm, simply fry an egg separately and serve it alongside the hash.
For a unique sweet and savory spin, consider adding a spoonful of homemade bourbon bacon chutney on top – its complex flavors will truly pop. Beyond that, a simple dollop of sour cream or crème fraîche, a few slices of fresh avocado, a dash of your favorite hot sauce, or a squeeze of fresh lemon juice can all provide excellent finishing touches, adding brightness and enhancing the overall experience. Don’t be afraid to experiment with toppings to discover your perfect combination!


Storage & Reheating Tips
If you find yourself with leftovers of this delightful Brussel sprout hash, rest assured it stores beautifully. Simply transfer the cooled hash to an airtight container and refrigerate for up to 4 days. When you’re ready to enjoy it again, you have a couple of options for reheating. You can gently warm it in the microwave until heated through, or for a crispier result, reheat it in a skillet over medium heat on the stove, stirring occasionally, until it’s hot and some of those delicious crispy bits return.
Frequently Asked Questions (FAQ)
Absolutely! Cabbage makes a wonderful substitute. You can shred it just like you would the Brussels sprouts. If you’re feeling adventurous, add some cooked potatoes and corned beef for a delicious Irish-inspired breakfast hash.
The key to reducing bitterness in Brussels sprouts lies in proper cooking. High heat (like sautéing or roasting) encourages caramelization, which brings out their natural sweetness and mellows any bitter notes. Additionally, ensuring they are fresh and not overcooked helps. Some people find that soaking them in cold water for 15-20 minutes before cooking can also help draw out some bitterness, though the shredding and sautéing method in this recipe is usually sufficient.
