Total Time: 45 minutes

Rich Mustard Beef with Mushrooms - the perfect meal for the whole family


  • 455g (1lb) of extra lean ground beef
  • 225g/8oz of fresh baby Portobello mushrooms (or chestnut mushrooms) - do not use frozen
  • 2 red onions, sliced finely
  • 3 cloves of garlic crushed
  • 400ml of beef stock and 80ml for browning mushrooms/onions (480ml/2cups in total)
  • 1 tablespoon of wholegrain mustard
  • 1 tablespoon of arrowroot flour
  • pinch of dried thyme
  • 1 tablespoon of balsamic vinegar (good quality aged)
  • 2 tablespoons of tomato puree (paste
  • salt and pepper to season
  • fresh chopped Italian parsley to serve


  1. Add the ground beef to a frying pan over a medium high heat, seasoned with salt and black pepper and fry until browned. Transfer to another dish and set aside.
  2. Spray the frying pan with some spray oil.
  3. Add the onions and garlic and cook until softened.
  4. Add the mushrooms and a little bit of the stock at a time, and continue to cook until the onions and mushrooms get nice and caramelized. Don't skip or rush this stage, caramelization is important and what adds depth to the sauce.
  5. Return the mince to the pan, along with a sprinkling of thyme, tomato puree (paste), balsamic vinegar, mustard, remainder of stock and a good pinch of salt and pepper to season.
  6. Mix the cornstarch with a couple of teaspoons of water and add this into the pan (it will thicken the sauce).
  7. Bring to a boil and then reduce heat and simmer for approx 20mins
  8. Serve topped with parsley and your choice of sides.
  9. Enjoy!!

    I made this in my slow cooker (crock pot) and it was delicious!
    6 hours on low.
    I dry fried the mince first to brown it & added the cornflour at the end to thicken it.
    It turned out perfect & will definitely cook it again!

  13. DebbieBailey says

    Thank you!


  14. Sheila R says

    This looks really lovely, did try some and tastes good too! Thank you for sharing, it's a recipe which has many uses!


  15. afra says

    Super simple weeknight dish. Really enjoyed it. Used a little less mince meat and added cauliflower rice at the moment I returned the meat to the pot. Was lovely with cauli mash.



    Outstanding! I did it as a pot roast. Browned the pot roast in a dutch oven, sauteed onions, carrots and mushrooms. Placed in the oven, at 350, for 3 hours. It was so delicious! Your recipe made the most delicious sauce/gravy. I'll be making this every month. Thank you!


  17. Name Linda Harding says

    I made this for tonight's dinner, both myself and my husband liked it very much.


  18. Julie says

    This looks amazing, but I just want to clarify one ingredient, as I know names can vary according to countries...
    The recipe calls for 2 tbsp tomato puree (which where I am is basically blended up cooked tomatoes) but by the richness off the colour of the dish I am wondering if you mean what I would call tomato paste, a much more concentrated tomato product?
    Hope that all makes sense. Looking forward to trying this once I have clarified this ingredient.


    • Siobhan (Slimming Eats) says

      yes tomato puree is tomato paste - enjoy!!
