Prep: 20 min | Cook: 25 min | Total: 45 min
Servings: 12 mini tarts
Ingredients
- 1 sheet puff pastry, thawed
- 4 slices bacon
- 1 medium onion, finely sliced
- 1 cup shredded cheese (mix of sharp cheddar and Gruyère)
- 2 large eggs
- 1/2 cup heavy cream
- Salt and pepper to taste
- Fresh thyme for garnish (optional)
Instructions
- Heat 1 tablespoon of oil in a frying pan over medium heat. Add the sliced onions and cook slowly, stirring occasionally, until soft and golden brown, about 15 to 20 minutes. Season with a pinch of salt and set aside to cool.
- In the same pan, cook the bacon slices until crispy. Place the cooked bacon on a paper towel to absorb excess grease, then chop into small pieces.
- Preheat the oven to 400°F (200°C). Roll out the puff pastry on a lightly floured surface and cut into 12 squares, each about 4 inches in size. Score a border about half an inch from the edge of each square to create a frame.
- Place the puff pastry squares on a baking sheet lined with parchment paper. Evenly distribute the caramelized onions, chopped bacon, and shredded cheese over the pastry bases.
- In a bowl, whisk together the eggs, heavy cream, salt, and pepper. Carefully pour the egg mixture over the toppings on each pastry square, avoiding overflow.
- Bake in the preheated oven for 20–25 minutes, or until the edges are golden and the filling is set.
- Remove from the oven and let cool for a few minutes. Garnish with fresh thyme if desired. Serve warm.

Ingredients
Here’s what you’ll need for about 12 mini tarts:
- 1 sheet of puff pastry (thawed)
- 4 slices of bacon
- 1 medium onion, finely sliced
- 1 cup of shredded cheese (I love using a mix of sharp cheddar and Gruyère)
- 2 large eggs
- 1/2 cup of heavy cream
- Salt and pepper to taste
- Fresh thyme for garnish (optional)
Instructions
Now, let’s start making the tarts!
Step 1: Preparing the Caramelized Onions
First, I heat a tablespoon of oil in a frying pan over medium heat and add the sliced onions. I like to cook them slowly, stirring occasionally, until they become soft and golden brown — this usually takes about 15 to 20 minutes. Once they reach the desired color, I season them with a pinch of salt and set them aside to cool.
Step 2: Cooking the Bacon
In the same frying pan, I add the bacon slices and cook them until they’re crispy. Afterward, I place the bacon on a paper towel to absorb excess grease before chopping them into small pieces. This step adds a savory crunch to the tarts!
Step 3: Preparing the Puff Pastry
Next, I preheat the oven to 400°F (200°C). While that heats up, I take the puff pastry and roll it out on a lightly floured surface. I then cut it into 12 squares, each about 4 inches in size. Using a knife, I score a border about half an inch from the edge of each square to create a frame.
Step 4: Assembling the Tarts
Now comes the fun part! I place the puff pastry squares on a baking sheet lined with parchment paper. In a bowl, I whisk together the eggs, heavy cream, salt, and pepper. I then evenly distribute the caramelized onions, chopped bacon, and shredded cheese over the pastry base. Finally, I pour the egg mixture carefully on top, making sure not to overflow the edges.
Step 5: Baking the Tarts
I pop them in the oven for about 20-25 minutes, or until the edges are golden and the filling is set. The smell of baking cheese, bacon, and onions is irresistible!
Step 6: Serving
Once they are out of the oven, I let them cool for a few minutes, then garnish with fresh thyme if I have it on hand. These tarts are best enjoyed warm and can be served as an appetizer or snack. Your guests will surely be impressed!
These Mini Cheese and Bacon Tarts with Caramelized Onions are a fantastic addition to any gathering. I hope you enjoy making and devouring them just as much as I do!
