Why do I love the Sweet Onion and Bacon Tart recipe? Let me count the ways. First of all, the combination of sweet, caramelized onions and crispy, savory bacon hits all the right notes. I first stumbled upon this delicious concoction while experimenting with various mountain-inspired meals, drawn to its hearty yet elegant flavors reminiscent of home-cooked comfort food, perfect for a chilly evening in the Rockies.
Layers of Flavor
The magic begins with a ready-made pie crust, making it convenient for even the busiest of us. The sweet onion is slowly sautéed with olive oil, brown sugar, and a splash of balsamic vinegar, creating layers of deep, rich flavor. When combined with Gruyère cheese, heavy cream, and eggs, it transforms into a wonderfully creamy filling. Of course, the crumbled bacon adds that irresistible extra layer of complexity, offering a delightful contrast in texture and taste.
Health Benefits
Yes, this tart tastes decadent, but it also carries surprising nutritional benefits. Onions are packed with antioxidants and have anti-inflammatory properties that are great for overall health. Eggs provide a good source of protein and essential vitamins. Even bacon, in moderation, contributes necessary fats that can keep you feeling satisfied longer. Combined with the calcium and protein from the Gruyère cheese, you’re looking at a well-rounded dish that pleases both your palate and your body.
This tart is somewhat similar to a traditional quiche but with a more robust blend of flavors, making it an excellent choice for brunch, lunch, or dinner. If you want to keep the mountain-inspired theme going, it pairs wonderfully with a simple arugula or mixed greens salad, dressed with a light lemon vinaigrette. If you’re in the mood for more, consider serving it alongside a bowl of hearty potato leek soup or a slice of my rustic rosemary bread.

What You’ll Need
- 1 ready-made pie crust
- 1 large sweet onion, thinly sliced
- 6 slices of bacon, cooked and crumbled
- 1 cup shredded Gruyère cheese
- 1/2 cup heavy cream
- 3 large eggs
- 1 tablespoon olive oil
- 1 tablespoon brown sugar
- 1 tablespoon balsamic vinegar
- Salt and pepper to taste
Method
Step One
Preheat your oven to 375°F (190°C).
Step Two
Roll out the ready-made pie crust and fit it into a tart pan. Trim any excess dough hanging over the edges. Prick the bottom of the crust with a fork. Place the crust in the oven and blind bake for about 10 minutes or until lightly golden.
Step Three
In a large skillet over medium heat, add the olive oil. Once heated, add the thinly sliced sweet onion. Cook, stirring occasionally, until the onions start to soften, about 5 minutes.
Step Four
Sprinkle the brown sugar over the onions and continue to cook for another 10 minutes, stirring frequently, until the onions are caramelized. Add the balsamic vinegar and cook for an additional 2 minutes. Season with salt and pepper to taste. Remove from heat and let cool slightly.
Step Five
In a large bowl, whisk together the heavy cream and eggs until well combined. Season with a pinch of salt and pepper.
Step Six
Evenly spread the caramelized onions over the bottom of the pre-baked tart crust. Sprinkle the crumbled bacon over the onions. Pour the cream and egg mixture over the top and spread evenly.
Step Seven
Sprinkle the shredded Gruyère cheese evenly over the tart filling.
Step Eight
Place the tart back in the oven and bake for 25-30 minutes, or until the filling is set and the top is golden brown.
Step Nine
Remove the tart from the oven and let it cool for a few minutes before slicing. Serve warm or at room temperature.
