Ingredients You’ll Need

The ingredients in this Brussels Sprouts Tartine Recipe work together to balance sweetness, savory richness, and bright freshness—making it a harmonious flavor party on bread. When shopping, look for firm Brussels sprouts and good-quality sourdough, as they really make a difference.

• Sweet onion: Choose a fresh, firm onion for that perfect caramelized sweetness.
• Garlic clove: Fresh garlic enhances the depth of flavor without overpowering the tartine.
• Unsalted butter: Using unsalted lets you control the saltiness in your dish.
• Brussels sprouts: Pick small to medium-sized ones that are compact and bright green for best crispiness.
• Olive oil: A good-quality extra virgin olive oil adds a lovely richness to the sprouts.
• Kosher salt: Enhances all the flavors without being too harsh.
• Freshly cracked black pepper: Adds a bright, warm spice note.
• Sourdough bread slices: Thick slices with a sturdy crumb hold up well to toppings and toasting.
• Havarti cheese: This mild, creamy cheese melts beautifully and complements the brussels without competing.
• Lemon: Fresh lemon slices add a pop of brightness that cuts through the richness.
• Parmesan cheese: Finely grated to sprinkle on top for an extra savory boost.

Variations

One of the things I enjoy most about the Brussels Sprouts Tartine Recipe is how easy it is to make it your own. Whether you want to boost the protein, make it dairy-free, or give it a different flavor twist, this recipe is flexible enough to adapt.

• Add a Protein: I like topping mine with a fried egg or some crispy bacon for an added savory bite that takes brunch to the next level.
• Swap the Cheese: Goat cheese or creamy ricotta work beautifully if you want a tangier or lighter cheese option.
• Dairy-Free Version: Use a plant-based butter and cheese alternative, then sprinkle with nutritional yeast for cheesy umami.
• Seasonal Twist: In winter, I sometimes add a pinch of nutmeg to the caramelized onions for warmth, or toss in some toasted walnuts on top for crunch.

How to Make Brussels Sprouts Tartine Recipe

Step 1: Caramelize the Onions and Garlic Slowly

Start by heating unsalted butter in a skillet over medium-low heat. Add your thinly sliced sweet onions and minced garlic with just a pinch of salt to help pull moisture out. Cook slowly, stirring often, for about 20 to 30 minutes. You want the onions to become golden brown and sweet—don’t rush this step! Watching the onions transform is like watching magic happen, and it’s the backbone of flavor here.

Step 2: Crisp the Brussels Sprouts

Next, in a separate skillet (or after removing the onions), warm olive oil over medium-high heat. Toss in the sliced Brussels sprouts with a good pinch of kosher salt and freshly cracked black pepper. Stir occasionally, letting them brown and crisp up — those caramelized edges add incredible texture. You want a bit of crunch but keep them tender inside, so keep an eye on the heat and timing.

Step 3: Toast the Sourdough

While your veggies are cooking, place sourdough slices on a baking sheet and pop them into your 350°F oven. Toast them for 10 minutes, then flip and toast another 10 minutes to achieve a sturdy yet crunchy base. When you add the freshly grated Havarti cheese, return the bread to the oven just long enough for it to melt into gooey perfection without drying out.

Step 4: Assemble and Serve

Once everything’s ready, top each cheesy toast first with the caramelized onions, then a generous pile of the crispy Brussels sprouts. Brighten it all by spritzing with fresh lemon juice, then finish with a sprinkle of freshly grated Parmesan. Serve immediately so the tartine stays warm and all the flavors shine together.

How to Serve Brussels Sprouts Tartine Recipe

Garnishes

I usually top mine with a few extra shavings of Parmesan and a light drizzle of good olive oil for shine and a little richness. Sometimes I add a sprinkle of toasted pine nuts or cracked black pepper right before serving to give it a bit more texture and zing.

Side Dishes

This tartine pairs beautifully with a crisp green salad or a bowl of roasted root vegetables for a complete, well-rounded meal. When I want something heartier, a cup of butternut squash soup on the side complements the flavors perfectly.

Creative Ways to Present

For a dinner party, I’ve served these tartines on a wooden board dressed with fresh herbs scattered around. You can cut them into smaller toasts for a charming appetizer, or build an open-faced tartine bar where guests add their own toppings—such a fun and interactive way to enjoy it.

Make Ahead and Storage

Storing Leftovers

I store leftover Brussels Sprouts Tartine components separately—the caramelized onions and sautéed Brussels sprouts in airtight containers in the fridge, and the toasted bread in a paper bag to keep it crisp. When stored this way, everything stays fresh for 2-3 days.

Freezing

I’ve found that freezing the assembled tartines isn’t ideal because the bread gets soggy. But you can freeze the caramelized onions and Brussels sprouts separately for up to a month and thaw them before quickly reheating.

Reheating

To bring leftovers back to life, I gently reheat the veggies in a skillet over medium heat to crisp them up again, and toast the bread slices separately. Then assemble right before serving, finishing with fresh lemon and Parmesan to revive the flavors.
