Instructions
 

Step 1: Prepare All The Ingredients

  • Wash and prepare all the vegetables before you begin cooking.
  • Dice the onions, slice the carrots and celery, chop the peppers, and finely chop the garlic.
  • Drain and rinse both tins of beans.
  • Measure the herbs, spices and vegetable stock so everything is ready to use.
  • Having all your ingredients prepared first makes cooking Quorn Sausage Casserole with Beans much smoother and helps prevent overcooking.

Step 2: Brown The Quorn Sausages

  • Heat 1 tablespoon of olive oil in a large heavy-based casserole pot over a medium heat.
  • Add the Quorn sausages.
  • Cook for 6–8 minutes, turning regularly until lightly golden on all sides.
  • They do not need to be fully cooked through at this stage as they will continue cooking in the casserole.
  • Transfer the sausages to a plate and set aside.
    • Browning the sausages first adds extra flavour and improves their texture.

Step 3: Cook The Vegetables

  • Add the remaining tablespoon of olive oil to the same pot.
  • Stir in the onions.
  • Cook gently for 4–5 minutes until softened.
  • Add the carrots, celery and peppers.
  • Continue cooking for another 5 minutes, stirring occasionally.
  • Add the chopped garlic.
  • Cook for 1 minute, just until fragrant.
    • Avoid letting the garlic brown, as it may become bitter.

Step 4: Build The Rich Tomato Base

  • Stir in the tomato purée.
  • Cook for 2 minutes, allowing it to caramelise slightly.
  • Pour in both tins of chopped tomatoes.
  • Add the vegetable stock.

    • Add the cannellini beans.
    • Mix gently to avoid breaking the beans.

    Step 7: Return The Quorn Sausages

    • Slice each browned Quorn sausage into chunky pieces if preferred, or leave them whole.
    • Return them to the casserole.
    • Stir gently so they are coated in the tomato sauce.

    Step 8: Simmer Slowly

    • Bring the casserole to a gentle simmer.
    • Reduce the heat to low.
