How to Make Brussels Sprouts Toast with Caramelized Onions

Step 1: Prepare the Brussels sprouts

Trim and thinly slice the Brussels sprouts. This helps them cook quickly and evenly, developing a tender yet slightly crisp texture perfect for the toast topping.

Step 2: Caramelize the onions

Heat olive oil or butter in a skillet over low heat, then add thinly sliced yellow onions. Allow them to cook slowly, stirring occasionally, until they turn a rich golden brown and release their natural sweetness. This can take 20 to 30 minutes but is worth every second.

Step 3: Sauté the Brussels sprouts

In a separate pan, heat oil or butter and add the sliced Brussels sprouts and minced garlic. Cook over medium heat until tender and caramelized edges form, about 8 to 10 minutes. Season with salt and pepper to taste.

Step 4: Toast the bread

While the veggies cook, toast your bread slices until golden and crisp. This base will hold up well under the moist toppings and add wonderful texture contrasts.

Step 5: Assemble the toast

Layer the caramelized onions evenly over the toasted bread first, then pile on the sautéed Brussels sprouts. If using, sprinkle with cheese or your favorite garnish before serving immediately.

Pro Tips for Making Brussels Sprouts Toast with Caramelized Onions

• Slice thinly: Thin slices of Brussels sprouts cook faster and have a better mouthfeel on toast.
• Go low and slow for onions: Patience is key when caramelizing onions to develop that perfect deep flavor and texture.
• Use sturdy bread: Thick-cut, crusty bread is best to hold the toppings without getting soggy.
• Season thoughtfully: A pinch of salt and pepper enhances every ingredient; don’t skip this step.
• Warm toppings before assembling: This keeps the toast tasty, especially if serving right away.
