Serving the same dishes three times just won’t do! This calls for creativity, thoughtful planning, and an array of diverse recipes to delight everyone around the festive table.

For many, myself included, the anticipation of the holidays is intrinsically linked to the joy of planning and coordinating each celebratory meal. It’s a passion of mine!

I truly hope it provides you with plenty of delicious ideas!

The Secret to the Best Caramelised Brussels Sprouts Hash

The true magic behind this sensational Brussels sprouts recipe lies in the art of caramelisation. This culinary technique is what transforms humble vegetables into something truly extraordinary. We begin by frying the sliced leeks, not just in any oil, but using the rich, unctuous fat rendered from the pancetta. This not only keeps the pan perfectly slick but also infuses the leeks with an incredible depth of savory flavor right from the start. As the leeks gently cook over a low heat, their natural sugars slowly break down and caramelise, creating a beautiful dark sear on the vegetables and building a sweet, aromatic foundation for the entire dish. This process demands patience; a low and slow approach is key to developing that deep golden-brown color and preventing any sticking or burning, ensuring maximum flavor development.

Once the leeks have achieved that pleasing golden hue and filled your kitchen with their fragrant aroma, we introduce a delightful concoction of apple cider vinegar and maple syrup to the pan. This combination is a stroke of genius, as the acidity of the vinegar brightens the flavors, while the maple syrup enhances the caramelisation, adding another layer of sweet complexity. As these liquids mingle with the leeks and reduce, they begin to take on a wonderfully sticky, glaze-like consistency, coating every piece of vegetable with an irresistible sweet-tangy finish. This step is crucial for achieving the signature “caramelised” aspect of our Brussels sprouts hash.

The final stage brings together the heart of our dish: the leafy greens. Fresh kale and thinly sliced Brussels sprouts are added to the pan, along with a flavorful stock. Simmering these vegetables in the rich, apple-tinted broth ensures they cook to perfect tender-crisp doneness, absorbing all the wonderful flavors from the leeks, pancetta, maple, and apple cider vinegar. This braising method allows the greens to steep, drawing out their natural earthy notes and infusing them with the sweet and savory elements of the braise. The result is a harmonious blend of textures and tastes that will convert even the most skeptical Brussels sprout eaters.

While Brussels sprouts are often considered a divisive vegetable, finding a recipe that everyone can genuinely enjoy is entirely possible. This caramelised hash is certainly a strong contender, offering a flavor profile that appeals to a wide range of palates. If you’re looking for more ways to make sprouts a hit, here are a few other fantastic options to try: our creamy Brussels Sprouts Gratin with Crispy Breadcrumbs, a delectable combination of Maple-Glazed Brussels Sprouts and Sweet Potatoes, the simple elegance of Carrots and Sprouts generously drifted in Parmesan, and for the bacon lovers, Crispy Brussels Sprouts and Bacon drizzled with Sweet Honey. Each offers a unique way to enjoy this often-misunderstood vegetable.

Essential Recipe Tips and Notes for Perfect Caramelised Brussels Sprouts

  • Efficient Preparation is Key: Before you even think about turning on the stove, ensure all your vegetables are prepped and ready to go. This means thinly slicing the leeks, trimming the tough ends off your Brussels sprouts and halving or quartering them, and de-ribbing and slicing the kale. This mise en place approach makes the cooking process much smoother and faster. For an even quicker prep, consider using a food processor with a slicing attachment for the sprouts and leeks.
  • Pancetta Alternatives: While pancetta lends a unique, subtly spiced flavor, if you find it hard to source, good quality thick-cut bacon or streaky bacon (as it’s often called in the UK) makes an excellent and readily available substitute. The rendered fat from either will provide that essential base for caramelising the leeks.
  • Mastering the Caramelisation: The caramelisation stage is where the magic happens, but it also requires your full attention. Keep a close eye on the pan at all times. A delicate, sweet caramel can quickly tip into bitter, charred territory if left unattended for even a moment. Cook over a truly low heat, stir frequently, and don’t rush the process. If you notice it browning too quickly, slightly reduce the heat and add a tiny splash of water or stock to cool the pan down.
  • Leek Cleaning: Leeks can often hide dirt and grit between their layers. To clean them thoroughly, slice the leeks first, then immerse them in a bowl of cold water, swishing them around to dislodge any soil. Lift them out with a slotted spoon, leaving the grit behind.
  • Choosing Fresh Produce: Select firm, vibrant green Brussels sprouts with tightly packed leaves. Avoid any with yellowing or soft spots. For kale, look for crisp, dark green leaves. Fresh, high-quality ingredients will significantly impact the final flavor of your hash.

What to Serve with Caramelised Brussels Sprouts Hash

This Caramelised Brussels Sprouts Hash was specifically created with the grandeur of holiday meals in mind, making it an ideal Thanksgiving dinner side dish or a festive accompaniment for any special occasion. The combination of sweet, soft, and richly simmered greens makes it a versatile complement to a variety of main courses.

It pairs particularly well with classic holiday proteins. Imagine serving this alongside a succulent Herb Butter Roast Turkey Crown or Breast. The luscious, moist texture of the hash provides a wonderful counterpoint to roasted meats, acting as a delicious insurance policy against any accidental dry white meat! The slight sweetness and savory depth of the sprouts and leeks perfectly balance the richness of turkey or a traditional roast chicken.

Beyond poultry, this hash also makes a fantastic partner for other festive roasts. Consider pairing it with a beautifully cooked pork loin or a tender beef roast. The savory pancetta and sweet caramelised vegetables will enhance the natural flavors of the meat without overpowering them.

And, of course, no holiday meal is complete without potatoes. This year, I’ll be serving my Caramelised Brussels Sprouts Hash alongside perfectly crisp-shelled and fluffy-centered Classic Roast Potatoes. The different textures and flavors of these two side dishes will create a truly memorable plate. For a lighter touch, it also complements creamy mashed potatoes or a simple rice pilaf. Don’t forget a rich gravy, perhaps a Red Onion Gravy, to bring all the elements together harmoniously.

Storage and Leftovers: Maximising Your Holiday Feast

If you’re anything like me, the holiday season brings a unique kind of culinary stress: first, the frantic worry that there won’t be enough food to feed everyone at Thanksgiving dinner, and then, immediately after, the equally panicked realization that you now have to find space in your refrigerator for an avalanche of delicious leftovers! Fortunately, the remnants of a festive blow-out meal are not only inevitable but also incredibly versatile and easily reinvented.

This Caramelised Brussels Sprouts Hash is no exception. Any remaining hash will keep beautifully when covered tightly and stored in the refrigerator for 3-4 days. This makes it a fantastic make-ahead option or a convenient ingredient for future meals. Don’t let those delicious, flavor-packed greens go to waste!

One of my favorite ways to give this hash a second life is as a vegetable-packed and deliciously low-carb topping for a classic Cottage Pie. Instead of a traditional mashed potato layer, simply spread the leftover hash over your savory meat filling. The sweet and savory notes of the leeks and sprouts, combined with the pancetta, add an unexpected depth and richness to the pie, making it a truly elevated comfort food experience. It’s a wonderful way to sneak in extra vegetables and add complex flavors to a family favorite.

Beyond Cottage Pie, consider these other creative ideas for your leftover Brussels sprouts hash:

  • Breakfast Hash: Reheat the hash in a pan and top it with a fried or poached egg for a hearty and nutritious breakfast. The runny yolk will mingle perfectly with the caramelized vegetables.
  • Quick Side Dish: Simply reheat and serve alongside grilled chicken, baked salmon, or even as a warm salad base for a quick weeknight meal.
  • Stuffed Peppers or Mushrooms: Mix the hash with a little cooked rice or quinoa, stuff it into bell peppers or large mushroom caps, and bake until tender for a flavorful vegetarian main.
  • Savory Tart or Quiche Filling: Incorporate the hash into a quiche or tart filling for a sophisticated brunch or light dinner option. Its robust flavors will shine.
  • Soup Booster: Add a spoonful or two to vegetable or chicken broth for an instant flavor boost and added texture to a simple soup.

With these ideas, you’ll never dread holiday leftovers again – in fact, you might even look forward to them!

More Delicious Side Dishes to Try This Holiday Season

  • Rich Red Onion Gravy: A deeply flavorful gravy perfect for any roast, adding a touch of sweetness and umami to your plate.
  • Fresh Green Bean Casserole: A vibrant and modern twist on the classic, featuring crisp fresh beans in a creamy sauce, a must-have for your holiday spread.
  • Walnut Beet Salad with Garlic Mayonnaise Dressing: A colorful and refreshing salad that offers a lovely earthy sweetness and a tangy kick, providing balance to heavier dishes.

Brussels sprouts with pancetta and leeks in a large pan

Caramelised Brussels sprouts combine salty pancetta, sweet maple-caramelised leeks, sprouts, and kale simmered in a brothy braise.

Ingredients

  • 65g / 2 oz diced pancetta, or thickly sliced bacon
  • 1 tbsp olive oil
  • 2 leeks, sliced
  • 3 cloves garlic, minced
  • 3 tbsp apple cider vinegar
  • 1 tbsp maple syrup
  • 3-4 thyme sprigs, leaves only
  • 1 bay leaf
  • 500g / 1 lbs Brussels sprouts, sliced
  • 6 kale leaves, sliced
  • 2/3 cup chicken stock, or vegetable stock
  • Salt to taste

Instructions

  1. Before starting to cook, prepare all ingredients. Cut the stalks off the sprouts and remove any damaged outer leaves, then slice them finely. Next, slice the leeks and kale. To speed up the process, you can use the slicing attachment on a food processor.

  2. Heat a large frying pan for which you have a lid. Fry the diced pancetta or bacon until the fat renders and it becomes crispy. Now, add the sliced leeks to the pan and cook over low heat until they begin to caramelise, turning golden brown. Add a tablespoon of olive oil if the pan seems too dry. After about 10 minutes, mix in the minced garlic and cook for an additional 30 seconds until fragrant. Pour in the apple cider vinegar and maple syrup and continue cooking, stirring constantly, until the leeks get darker and develop a sticky caramelisation. Watch this process carefully as the leeks can go from perfectly caramelised to burned very quickly.

  3. Now, add the chicken or vegetable stock, the sliced Brussels sprouts, kale, thyme, and bay leaf. Stir everything to combine thoroughly. Add a pinch of salt, then cover the pan with the lid. Cook over medium heat for 10 minutes, stirring halfway through the cooking time to ensure even cooking and to prevent sticking or burning. Uncover and test the vegetables for doneness. They should be cooked through and tender-crisp. If they are not completely done, add a splash of water or more stock and continue cooking for a few more minutes until desired tenderness is reached. Season with additional salt to taste before serving hot.
