How to Make Caramelized Onion and Goat Cheese Montaditos
Ingredients
- 1 fresh baguette, cut diagonally to make 2.5 cm (1-inch) thick rounds
- 200 g (3.5 oz) fresh goats cheese (room temp is best for spreading)
- 3 large onions, sliced fine (300g / 10.5 oz.)
- 3 tbsp extra virgin olive oil
- 2 tbsp balsamic vinegar
- 1 tsp white sugar
- Salt to taste
- A few fresh basil leaves (whole)
Equipment
- Large cast iron pan or cast iron Dutch oven
- Wooden spatula
- Cutting board
- Chef knife
Instructions
Step 1 – Prepare The Caramelized Onions
- Heat a cast iron pan on medium high heat.
- Tip: Now’s a good time to take your goat cheese out the fridge to come to room temp.
- Once the pan is hot, add onions without oil and stir frequently. Cook for around 5 minutes.
- Add the olive oil, sugar, and salt, stirring constantly to combine the ingredients.
- Reduce the heat to medium-low and cook slowly for around 40 minutes, stirring every 8–10 minutes. Add a splash of water whenever the onions begin sticking to the pan.
- At the 40 minute mark, add the balsamic vinegar and gently stir through the onions. Cook on low for another 5 minutes, stirring occasionally.
- Be sure to give the pan edges a good scrape to bring up the flavor.
Step 2 – Toast The Baguette (optional)
- Toast the sliced baguette rounds under the grill for 1-2 minutes or until lightly golden.
- Keep a constant eye on the bread while it toasts, as it will blacken quickly.
Step 3 – Add Toppings
- First, top the toasted baguette with plenty of goat’s cheese, then add a spoonful of caramelized onion on top. Repeat steps with the remaining ingredients.
Step 4 – Serve
- Garnish with a few fresh basil leaves and serve.
NOTE: Serve warm or at room temperature.
These montaditos are best served while the bread is still crisp and the onions are slightly warm, but they are also delicious at room temperature, making them perfect for parties and buffet tables.
Expert Tips:
Onions: Yellow onions work best because they become beautifully sweet after caramelizing, although white onions also work well.
Cook the onions slow and low: Take your time with the onions and allow them to cook slowly to create a delicious, sweet jammy texture that’s a wonderful mahogany color.
A little balsamic vinegar goes a long way: Don’t add too much balsamic vinegar or too early. Add 2 tablespoons 15 minutes before the onions are done.
Goat’s cheese: Use a soft fresh goat cheese log for the easiest spreading. Allow it to come to room temperature before assembling the montaditos.
Bread: A crusty French baguette gives the best texture, but ciabatta or sourdough slices are also excellent.

What Is a Montadito?
A montadito is a traditional Spanish open-faced sandwich served on a small slice of bread. The name comes from the Spanish verb montar, meaning “to mount” or “to assemble,” referring to the delicious toppings piled onto the bread. Montaditos are a staple of Spanish tapas culture and are designed to be enjoyed as a quick, flavorful bite alongside a drink.
A Staple of Spanish Tapas Culture
You’ll find montaditos served in tapas bars throughout Spain, from bustling cities to small village cafés. They’re perfect for sharing with friends and are often enjoyed as part of a larger selection of tapas. In northern Spain, particularly in the Basque Country, similar bite-sized snacks are known as pintxos (or pinchos) and are often secured with a cocktail stick, although the style and presentation can vary by region.
Popular Montadito Toppings
One of the best things about montaditos is their versatility. There are no strict rules when it comes to toppings, and every tapas bar has its own specialties. Popular ingredients include Jamón Ibérico, Manchego cheese, chorizo, anchovies, olives, roasted peppers, seafood, and fresh tomato. Vegetarian options are equally popular, with combinations of grilled vegetables, mushrooms, or creamy cheeses paired with sweet caramelized onions.
For this recipe, we’ve chosen one of the most loved flavor combinations: creamy goat cheese and rich balsamic caramelized onions served on crisp toasted baguette. It’s simple, elegant, and always a crowd-pleaser.
100 Montaditos
If you’ve travelled around Spain, you’ve probably come across 100 Montaditos, one of the country’s best-known tapas restaurant chains.
Famous for its menu of more than 100 different montadito fillings and budget-friendly prices, it’s become something of an institution in Spanish dining. While the chain has helped introduce countless visitors to montaditos, these delicious little sandwiches have been enjoyed in traditional Spanish bars and cafés for generations.
Why Goat Cheese and Caramelized Onions Are the Perfect Pair
Creamy goat cheese has a tangy flavor that balances the natural sweetness of slowly caramelized onions. As the onions cook, their sugars develop into rich, jam-like flavors that complement the fresh acidity of the cheese.
The toasted baguette adds crunch, creating a balanced bite that’s become a classic combination in Mediterranean and French cooking.
A few good brands worth checking out:
What Vinegar to Use for Caramelized Onions?
Use balsamic vinegar. It naturally balances the sweetness of the onions and creates a deep, rich jam-like texture that’s a wonderful mahogany color.
Buy it here: Giusti Italian Balsamic Vinegar of Modena IGP
You don’t need to add much. Add just a splash (about 2 tablespoons) near the end of the cooking process (about 15 minutes before the onions are done) to avoid burning.
If you don’t have balsamic vinegar, you can substitute sherry vinegar with a teaspoon of honey, although the finished onions won’t be quite as rich or sweet.
