Caramelized Onion Tart
Do you have a Guilty Pleasure List? Like brownies for breakfast or staying in your ‘night night’ clothes all day? That’s one of Lincoln and my favorites! Recently, we had a competition on who could stay in their ‘night night’ clothes the longest. Lincoln won. I had to run an errand. (dang!) However, he’s also had a contest with classmates on who could go the longest not washing their socks.
I wasn’t involved in that!
The winner lasts 2 weeks.
I’m sure a Mom intervened.
Sometimes, my guilty pleasure is cooking something very easy! It’s nice to have a very simple recipe. One that doesn’t require much time or thought! That’s why I like this Blue Cheese Caramelized Onion Tart.
The bonus? Every time I make it for guests, they rave about it! That makes me feel good.
This Blue Cheese Caramelized Onion Tart could be prepared as one large tart, in individual servings, or in appetizer portions.
To keep your eyes from stinging and watering while cutting onions, place the onion in the freezer for 15 minutes before you plan to start cooking. Chilling the onion slows the release of the enzyme responsible for teary eyes.
I have made it with just caramelized onions.
I have also made it adding with blue cheese and added a drizzle of balsamic reduction.
If I’m serving it as a side, I cut the sheet of puffed pastry into fourths.
I prefer it with blue cheese and balsamic reduction.
If you like a wonderful mix of flavors. Also try spring onion grilled pizza.
- You can substitute feta or goat cheese for the blue cheese.
- You’ll want to use a sweet onion like Vidalia or Texas Sweet.
- Add a drizzle of balsamic reduction for more flavor.

- 3 large sweet onions such as Vidalia, sliced
- 1 package puff pastry
- 1/4 cup blue cheese see post for substitutions
- For 8 servings, roll out one sheet puff pastry. Roll with a rolling pin until smooth and flat. Cut into 4 equal portions. Take square and fold over each side about 1/2 inch so that the edges are double thickness. This will better hold the ingredients in the center. Bake in 400 degree oven until golden brown about 20 minutes.
- Meanwhile, caramelize onions over low heat in 1 T butter or coconut oil until golden brown about 15 to 28 minutes
- Once pastry squares are golden, remove from oven and spoon onions in center of square. Top with blue cheese. Return to oven and bake until cheese melts. Serve immediately.
