Main Ingredients
- Brussels sprouts – fresh, firm, trimmed and halved (about 1 pound)
- Yellow or sweet onions – thinly sliced (2 medium)
- Olive oil – good quality extra virgin, for sautéing and drizzling (3 tablespoons total)
- Sourdough or rustic bread – sliced and toasted (4 slices)
- Salt – to taste
- Black pepper – to taste
- Lemon juice – fresh, a splash for finishing (about 1 teaspoon)
Optional Toppings
- Goat cheese or feta – crumbled (2 tablespoons)
- Toasted nuts (walnuts, pecans, or pine nuts) – a small handful
- Fresh herbs (parsley, thyme, or chives) – minced, for garnish
- Red pepper flakes or hot honey – for a spicy or sweet heat addition
- Prepare the Caramelized Onions: Thinly slice the onions. Heat 1 tablespoon of olive oil in a skillet over medium-low heat. Add the onions and cook slowly, stirring occasionally, for 20-25 minutes until they become golden brown, soft, and sweetly caramelized.
- Sauté the Brussels Sprouts: Trim the ends and halve the Brussels sprouts. Heat 2 tablespoons of olive oil in another pan over medium-high heat. Add the Brussels sprouts cut side down, cooking undisturbed for 3-4 minutes to sear them. Stir and cook for an additional 5 minutes until tender but still crisp.
- Toast the Bread: While the vegetables cook, toast 4 slices of sourdough or rustic bread until golden and crispy to create a sturdy base for the toppings.
- Assemble the Toast: Evenly layer the sautéed Brussels sprouts on each toasted slice. Spoon the caramelized onions generously over the sprouts. Sprinkle with salt and pepper, then drizzle fresh lemon juice over the top to brighten the flavors. Add any optional toppings such as crumbled cheese, toasted nuts, herbs, or a pinch of red pepper flakes if desired.
Notes
- Caramelize onions slowly over low heat to maximize sweetness without burning.
- Do not overcrowd the pan when searing Brussels sprouts to ensure even browning and crispness.
- Use day-old or slightly stale bread for better texture and to avoid sogginess when topped.
- Season with salt and pepper after assembling to keep the toast crisp.
- Fresh lemon juice added just before serving lifts and brightens the overall flavor.
- Store onions and sprouts separately from bread for best leftover quality.
