Roasting time will vary depending on the size of the tomatoes and the level of water they contain. Tomatoes containing ample seeds and water will need more time to roast. For example, roasting medium to large tomatoes cut into slices will require about ten to fifteen minutes at 350 degrees Fahrenheit. Roma tomatoes have fairly tough skins, and these usually require 40-45 minutes at 400 to roast in the oven.

Should you core tomatoes to remove the skins?

Suppose you are making sauces or soups, then removing the inner seeds and exterior skins is paramount for creating a robust flavor with a smooth consistency. However, if you are roasting tomatoes for adding to a pot roast, goulash, or pasta dish, leaving the core and skins would add flavor and texture to the dish. Also, leaving those vital parts of the tomatoes adds nutritional value and reduces food waste.

To remove the core and skins, start this process by filling a large pot with water on the stovetop to boil while you wash and remove the cores of the tomatoes.

Once the water is boiling, blanch the cored tomatoes by setting them in the boiling water for one to two minutes to loosen the skins. Remove from the boiling water and immediately set those hot tomatoes into a bowl with ice water.  As soon as the tomatoes are cool, remove those from the bowl and peel the skins off with your hands. Your cored and skinless tomatoes are ready for the next steps!

How do you know when tomatoes are done cooking?

There are a few variables to consider when examining roasted tomatoes. These include the type of tomatoes, cooking medium, and the other ingredients added. Also, if you are roasting tomatoes in a conventional or convection oven. Convection baking will reduce the roasting time by about ten to fifteen minutes.

Oven-roasted method

Oven-roasted tomatoes are ready when the skins show signs of blistering, caramelization, crispy edges, or the skins are removed from the tomatoes' inner pulp. Also, cherry tomatoes will blister and burst when they are fully roasted.

Stovetop method

Stove-top roasted tomatoes will show signs of completion when all the sides of the tomatoes show visual signs of caramelization or the edges are browned or charred. Also, another great indication is when the skins start to remove themselves from the inner pulp and seeds of the tomatoes.

Additional thoughts

Suppose you are using garden fresh tomatoes for the methods listed above. Always thoroughly wash each tomato with cold water and carefully inspect each one to ensure that there are no bugs or trapped bits of dirt hiding in the cracks or crevices of the tomatoes. Failure to wash the tomatoes could lead to a batch of poor quality roasted tomatoes that could cause upset stomachs or illnesses for those who are immunocompromised.

If you are using canned tomatoes- always check the expiration dates! If the can is expired, do not use it for roasting purposes. Consuming expired foods can cause serious harm. Never use any cans showing signs of botulism-- bloating, dented, or leaking cans are all signs of botulism and should be discarded immediately.
