I am sooo happy with how this recipe turned out. I had an image in my mind of what I wanted it to look like (and taste like!), and it turned out even better than I hoped. Perhaps I just don’t have very high expectations for myself – or perhaps this rich and tomatoey white bean gratin recipe is just that good. I think it’s the latter, but I’ll let you decide. Make it and let me know what you think!

What’s in this white bean gratin?
The crispy brown topping may not look like much, so perhaps a break down of the ingredients in this white bean gratin will convince you:
- cannellini beans
- a suuuper rich tomatoey sauce (with sun-dried tomatoes for extra flavour!)
- black olives
- pesto
- fragrant fresh basil
- and a crispy, cheesy topping
Now read that again, and imagine the smell. Flippin’ amazing. If it hadn’t been raining outside, I might almost have believed I was in the Mediterranean.

I wanted to keep this recipe really simple, so it doesn’t need any pre-cooking – just mix together a few ingredients, add the breadcrumbs, and bake. Hopefully my fellow lazy folk will appreciate that!
Usually, to get a really rich tomato sauce, you’d need to simmer it for ages and ages… but ain’t nobody got time for that. Instead, to avoid needing to pre-cook anything, just make sure you use a really good quality tin of tomatoes – I used my favourite Cirio tomatoes. If you use cheapy tinned tomatoes, this recipe will be rubbish. I’m warning you now! You really need the rich flavour from great tomatoes, and in my opinion Cirio is definitely the way to go. I promise, you will notice the difference as soon as you open the tin!

This tomatoey white bean gratin could be served as a main dish or a side, depending on what else you’re serving. Personally, I think it’s pretty amazing alongside just a green salad and a chunk of crusty bread (for mopping up that rich tomato sauce!). It would make a great protein-rich side dish too. Whatever floats your boat.

Instructions
- Preheat the oven to 190°C (Gas Mark 5 / 375°F).

I think I’m slightly addicted to buying tinned tomatoes – I’ve found 9 tins in the cupboard this evening! I love that you have a mental image of a dish before it is made.
Haha yes it’s the kind of thing that stacks up in the cupboard isn’t it! That and tins of beans ;)
