You won’t believe how this Aussie mum made a delicious meal with just 4 ingredients—and one costs only $1.20!

When it comes to feeding the family, we all want meals that are hearty, delicious, and—let’s be honest—don’t cost an arm and a leg or require a culinary degree to whip up.
If you’re tired of recipes that call for a laundry list of ingredients you’ll only use once (and then forget at the back of the pantry), you’re not alone! That’s why we’re always on the lookout for clever, budget-friendly meal ideas that don’t skimp on flavour or comfort.
Enter Aussie mum Bec, who’s taken the internet by storm with her four-ingredient roast lamb recipe.
Yes, you read that right—just four ingredients, and one of them is a humble $1.20 packet of French onion soup mix from Coles or Woolies (and if you’re really pinching pennies, you can even find similar packets for as little as 55c!).

Bec, who shares her allergy-friendly creations on social media as @mummyandmeeatallergyfree, has racked up over 100,000 views with this simple, mouth-watering winter warmer.
So, what’s the secret? It’s all about keeping things easy and letting the slow cooker do the heavy lifting. Here’s how Bec does it.
1. Layer chopped potatoes and carrots in the bottom of your slow cooker.
2. Place a boneless lamb leg roast on top of the veggies.
3. Rub the lamb with a packet of salt-reduced French onion soup mix—no need for fancy marinades or a spice rack full of herbs.
4. Cook 'low and slow' for 6–8 hours. When it’s nearly done, pop the lamb onto a tray and bake at 180°C for 30 minutes to get that irresistible crispy finish.
'It couldn’t be easier! You just dump the lamb into the slow cooker, tip the seasoning on top, pop the lid on and walk away!' Bec told Yahoo Lifestyle.
She swears it’s 'hands down the best roast' she’s ever had—and considering she’s just released her own slow-cooker recipe book, we’re inclined to believe her!
But the magic doesn’t stop there. Bec recommends saving the juices from the slow cooker, straining them, and whisking in a tablespoon of flour to create 'the world’s best gravy'. Talk about getting the most out of your ingredients!

'It’s such a versatile pantry staple—an easy way to build depth of flavour without needing lots of extra ingredients,' he says. Whether it’s pasta, risotto, or a creamy braised chicken dish, that little packet can transform a meal from bland to brilliant.
