Sabrina’s Bacon Blue Cheese Carmelized Onion Tart Recipe
I used to make this tart for client events (in all different flavors). I would make a giant batch ahead of time and freeze the rectangles. Then at the event, I could line up the rectangles on a bunch of cookie sheets and bake them off so I could get a quick appetizer out within minutes. This is one of the few recipes I think actually benefits from freezing. With no sensitivity to frost ingredients and puff pastry being in its best form frozen, thanks to the butter being colder, this is a perfect make-ahead appetizer.

About this Recipe
This tart is gorgeous, delicious and easy to make in just a few minutes. There isn’t a single weak link in this recipe either. Blue Cheese is added to the tart before and after baking so you get delicious caramelized blue cheese and creamy cool freshly added blue cheese in the same bite. Bacon, caramelized onions, Cream Cheese all on top of buttery, flaky, puff pastry.
Can this be made ahead of time?
- If you are going to freeze Bacon Blue Cheese Caramelized Onion Tart just stop after assembly and before baking and freeze completely on a baking sheet. Then you can stack them with layers of parchment paper in between so they don’t stick and you don’t get blue cheese on the bottoms of the pieces on top.

Sabrina,
This is a fabulous recipe! My friends have requested that I make it again for another gathering. This time, I will have to freeze it. Would you recommend freezing with all of the ingredients? How would you adjust the cook time for a frozen pastry? Thank you for your time!!
Yes, prepare and freeze, I think maybe just 2-3 more minutes in cooking (but watch closely towards the end).
Preparation and cooking times are only accurate if you already have caramelized onions and cooked bacon. Both of those take way longer than 5 minutes to prepare. Sounds tasty, though.
Like others, I cannot find any product named “Blue Cheese Simple Seasoning” or any combination of those words.
If it’s no longer available, please edit/modify your recipe so others can use another product. Not everyone is experienced enough to know they can substitute actual blue cheese for a powder.
Sabrina, I can not seem to find the artisan blue cheese seasons. Can you advise where to purchase this? Thank you
You can just use blue cheese crumbles too.
where does one find this blue cheese shaker? I’ve looked everywhere online and can’t seem to find it. I can’t even find a website for the company?
You can always get blue cheese crumbles from the cheese section on your grocer. I just looked on their site and don’t see it available anymore. https://www.litehousefoods.com/products/categories/blue-cheese-crumbles
This is truly fantastic! Just shared one with my daughter and she loves it too.
Thank you so much for the great recipe 🙂
Greetings from Poland in Europe 🙂
I’m so glad you both enjoyed it!
I’m not familiar with “Blue Cheese Simple Seasons” (a powder?). It sounds like FAKE Blue Cheese to me! This recipe sounds pretty good, despite the fake Blue Cheese which is being used in this recipe. I’ll substitute REAL Blue Cheese for the “Simple Seasons” fake stuff. I’m sure that it will taste a whole lot better with REAL Blue Cheese.
Blue Cheese Simple Seasons is real blue cheese but just crumbled and in a shaker container for easier use. It’s more for a convenience factor. I hope you enjoy the tarts.
Wow. I like blue cheese as much as the next guy, but dang. Lol.
Sounds and looks amazing! Just a question on the instructions… specifically #5 and #6.
The blue cheese crumbles in #6 isn’t mentioned in the ingredient list, nor the amount to use. Is it the same 1/4 c. Blue Cheese Simple Seasons in #5?
Also if ,previously frozen on parchment paper could it be kept on the parchment and placed on the baking sheet rather than transferred to the silicone mat?
Finally, could a premium quality Blue Cheese be added to the Cream Cheese to boost the flavor? I have friends and family who are crazy for blue cheese! I love the idea of the caramelized then cool Blues!
So sorry about the confusion! The blue cheese crumbles I used in this recipe are Blue Cheese Simple Seasons. You can definitely add in whatever Blue cheese you prefer I just wanted to show the ease with this product. Hopefully this clears it up!
Where can I get the Blue Cheese Seasons in Houston? Or what are the ingredients? Can’t seem to find the product. Thank you! Can’t wait to make this recipe!
This looks amazing ! If I pre make it and put it in the freezer, should I thaw it the day of the party? or change the cooking time if cooking from frozen?
You can either thaw it out or just bake an additional 3-4 minutes. Enjoy!
Best appetizer ever! So delicious!
Thanks for the 5 star rating, Dorothy!
Looks great! Do you assemble this with the puff pastry still frozen? And do you put it in the oven straight from the freezer, or does it need to thaw? Thanks!
It’s easier to assemble when the puff pastry is still a bit frozen (especially when spreading the cream cheese), then it goes straight into the oven.
This sounds so delicious. Love your combination of flavors!
This looks like an amazing tart. I can just imagine how wonderful this would taste.
Thanks, Dawn!
This would be great for when my husband travels for work and I want something easy!
I’ll let you in on a secret – I didn’t even let my husband know I made these until after they were gone! They’re that delicious!
I LOVE those blue cheese crumbles!
This is pretty much the best appetizer ever! I mean, how can you possibly go wrong with bacon, blue cheese, & caramelized onions?? 😉
If those ingredients are wrong, I don’t want to be right! 😉
Ahhhh this is a great appetizer!! I can’t wait to try it 🙂
Sabrina, you managed to put all of my favorite things in one bite.
Thanks!
This tart and that seasoning sound and look incredible!
Is there any other cheese you would suggest for a substitute? I adore blue but have family members that don’t like it…
You could try it with feta cheese also. Hope this helps!
I need to make this STAT! I love every single ingredient on this tart…I’m going to crave it until I can make one for myself.
