If you are looking for a more sustainable way to cook a Sunday roast, there are a few small changes you can make.

1. Choose a sustainable meat

Opt for meat that has been reared sustainably, such as organic, free-range, or pasture-raised. This means the animals have been given the space to roam and graze and are fed a more natural diet.

2. Buy local produce

Buying locally-sourced produce is a great way to reduce the carbon footprint of your meal and support local farmers. Look for meat and vegetables grown or reared within the country, or even better, within your region.

3. Cook on a low temperature

Cooking your roast on a lower temperature for a longer period of time will help it to cook more evenly and reduce the amount of energy you use.

4. Use a smaller joint of meat

Choose a smaller joint of meat that will be just enough for the number of people you are serving. This will reduce waste and save you money.

5. Don't over-roast your meat

Over-roasting your meat will make it tough and dry, and will also use more energy. Roast the meat until it reaches the recommended cooking time, or until a thermometer reads the desired internal temperature.

6. Use leftovers creatively

If you have any leftovers, don't let them go to waste! There are lots of ways you can use them up, such as making sandwiches, pies, stews, or soups.

By following these tips, you can cook a delicious and sustainable Sunday roast that is better for the environment and your health.
