Vegetables & Aromatics
- Fresh Brussels sprouts – 12 oz, trimmed and thinly sliced
- Yellow onions – 2 medium, thinly sliced
- Garlic – 2 cloves, minced
Fat & Seasoning
- Olive oil or butter – 3 tbsp (divided)
- Salt – to taste
- Black pepper – to taste
Bread & Optional Additions
- Rustic bread slices (such as sourdough or country loaf) – 4 slices
- Optional cheese (Parmesan or goat cheese) – 1/4 cup, crumbled or grated
- Prepare the Brussels sprouts: Trim the ends and thinly slice the Brussels sprouts to ensure they cook quickly and evenly, yielding a tender yet slightly crisp texture perfect for topping the toast.
- Caramelize the onions: Heat 1½ tablespoons of olive oil or butter in a skillet over low heat. Add the thinly sliced yellow onions and cook slowly, stirring occasionally, until they are a rich golden brown and have released their natural sweetness, approximately 20 to 30 minutes.
- Sauté the Brussels sprouts: In a separate pan, heat the remaining oil or butter over medium heat. Add the sliced Brussels sprouts and minced garlic, cooking until the sprouts are tender with caramelized edges, about 8 to 10 minutes. Season with salt and pepper to taste.
- Toast the bread: Toast the bread slices until golden and crispy, providing a sturdy base that holds up well to the moist vegetable toppings.
- Assemble the toast: Evenly layer the caramelized onions over each toasted bread slice, then pile on the sautéed Brussels sprouts. If desired, sprinkle with optional cheese or your favorite garnish. Serve immediately for the best texture and flavor.
Notes
- Slice Brussels sprouts thinly for faster cooking and better texture on toast.
- Caramelize onions slowly on low heat to develop deep flavor and perfect texture.
- Use thick-cut, crusty bread to prevent sogginess under the toppings.
- Season thoughtfully with salt and pepper to enhance all flavors.
- Warm toppings before assembling to keep the dish tasty when serving immediately.
- Store leftover components separately in airtight containers in the fridge for up to 2 days.
- Reheat gently on stovetop or oven and assemble toast just before serving to avoid sogginess.
- Optionally add nuts, fresh herbs, a spicy kick, or protein toppings like poached egg or smoked salmon.
