Recipe: Slow Oven Roasted Tomatoes

Hang on! Before you click away because of the 2 hour clock below, this dangerously delicious recipe only takes 5-10 minutes of your time to prep. The 2 hours comes once the tomatoes hit the oven… as my girl Martha Stewart once said ‘we’re going low and slow on this one’. These bad boys are great to meal prep on a Sunday and are so versatile. Serve them warm with some crackers as an app, throw them in a wrap for some extra flavour, or pop ’em into a pasta sauce for some nice texture and taste.

  • cherry tomatoes (I like the rainbow mix for some colour)
  • salt
  • 2-3 cloves of garlic
  • olive oil
  • crushed red chili flakes (optional)
Tomatoes, salt, red pepper flakes, serrated knife, garlic


Ok as I said above, don’t be discouraged by the 2 hours I’ve listed as the time for this recipe. You begin by investing a few minutes of your time to get these tasty, healthy tomatoes prepped. Once prepped, you can set them and forget them.

Start by preheating your oven to 225°F convection roast. Grab a rimmed baking sheet and if you like easy cleanup like me, cover it in some foil so once they’re done you can just chuck the cover out.

Now grab your pack of tomatoes and your biggest serrated knife (a bread knife works like a dream), it’s time to cut them. I learned this little trick that saves a ton of time – get two big tupperware lids, load the tomatoes in between and then slice right through with your knife. Bam! Tomato slicing production is at an all-time high! If you don’t want to use the tupperware trick, just slice the tomatoes in half with a serrated knife. Throw all your sliced tomatoes into a big bowl.

Now grab your garlic cloves and finely mince them, into the bowl they go! Add about 3-5 good pinches of salt, use your own judgement here. Same goes for the olive oil, a couple good glugs should do the trick. Finally, if you want to kick things up a bit, add some red chilli flakes. Toss all the goodies together, lay them out on the baking sheet and put them into the oven for about 2 hours. You’ll soon realize your house or apartment is filled with a glorious smell.

Pull them out and enjoy! As I said, they can be wolfed down warm on crackers (I love a good Mary’s whole grain cracker) or thrown into a sauce, wrap or sandwich.
