Hello lovelies,
Do you know what’s an absolute travesty? The fact I’ve never shared a savoury tart with you guys.
I was scrolling online when I had this overwhelming feeling of wanting to do a savoury tart. Like I say, I’ve never shared one here on my blog (from what I can remember anyway) and I thought it would be a nice change from all the sweet treats I’ve been sharing recently.
Although I mainly share sweet treats here on my blog, I’m actually a savoury gal at heart. That’s only changed the last couple of years but I’ve defiantly grown a love for savoury foods. So, as you can imagine, this tart is right up my street.
I’d never have thought about putting these ingredients together until I saw a recipe for a tart on Pinterest that had and it instantly caught my attention. If there’s one thing you should know about me, it’s that I have a great love for cheese & onion. Actually, it’s a slight obsession at this point. Likewise with pizza, I could quite easily eat anything that has cheese & onion on for every meal. Have I slightly concerned you or do you agree that cheese & onion is top tier?
I just know you guys are going to love how quick, easy and delicious this tart is. So before I ramble on anymore about my love for savoury, cheese & onion, let’s get into it:

Category: Savoury
Serves: 10-12
Prep Time: 40 Minutes
Cook Time: 25-30 Minutes
Overall Time: 60 Minutes
Ingredients You Need:
- 4-5 Red Onions, Sliced
- 1tbsp Of Butter
- 1tbsp Of Olive Oil
- 1 Sheet Of Ready-To-Roll Puff Pastry
- 1tbsp Of Balsamic Vinegar
- 184g Of Sour Cream
- 150g Of Blue Cheese, Crumbled
- 5 Slices Of Bacon, Cut Small & Cooked
- Pinch Of Pepper
How To Make Tart:
- Firstly, gather together your equipment and ingredients and line a baking tray with parchment paper.
- Secondly, in a pan on a medium heat, cook your bacon till crisp then set aside.
- Next, in a large frying pan over a medium-high heat, place the 1tbsp of butter and 1tbsp of olive oil in the pan and allow to heat up.
- Once heated, place your sliced onions into the pan and occasionally stir. Allow the onions to cook and caramelise for around 25-35 minutes (TIP: keep an eye on the heat of the pan, you may have to lower the heat if the onions begin to burn).
- When the onions have caramelised, add the 1tbsp of balsamic vinegar and mix into the onions then set aside.
- Now that the onions and bacon have been cooked, preheat the oven to 200C / 180C Fan / Gas Mark 6.
- In a large bowl, mix together the 184g of sour cream with the 150g of crumbled blue cheese and a pinch of pepper.
- On the lined baking tray, roll out your ready-to-roll puff pastry.
- Fold the edges of the puff pastry around 1/2inch to give the pastry a boarder so the centre doesn’t overflow.
- Spread the sour cream / blue cheese mixture onto the centre of the puff pastry and spread out to the edges.
- Next, sprinkle over your caramelised onions and crispy bacon.
- Now, place the baking tray into the oven and allow to cook for 25-30 minutes until the pastry is golden brown and cooked.
- Finally, take your tart out the oven and allow to cool on a wire rack.
That’s your Bacon, Caramelised Onion & Blue Cheese Tart prepared, baked and ready for you to demolish.
