Leftover Roast Beef Stroganoff

Jump to Recipe

I don’t know about you, but I love a Sunday roast. We occasionally have a midweek roast, but it’s rare, and when we do it’s much simpler. But, we have a Sunday roast most weeks. Meat, roast potatoes, roast veggies, mash, stuffing, and Yorkshire puddings. There’s always Yorkshire puddings, none of this, only with beef nonsense. When it comes to meat, honestly, I love them all, it just depends what I fancy. But, whatever we have, one of my favourite things in the world is creating an awesome leftover meal with whatever is left. Like this Leftover Roast Beef Stroganoff.

How Much?!

Chicken and Pork are generally quite a bit cheaper, and you can just buy enough for that one meal. If there’s any left, it tends to go on a sandwich for lunch the next day. But, when we’ve had roast beef or lamb, it’s a different matter. Beef and lamb can be a lot more expensive, so we tend to buy big, and make something amazing the next day. Especially useful if you are eating on a budget.

Curry is one of my go-to meals when it comes to using up leftovers, but anything cooked in a sauce or gravy is fantastic. Your meat stays nice and soft, and deliciously moist. This Leftover Roast Beef Stroganoff is brilliant.

Leftover Meals

Leftover Roast Beef Stroganoff in pot

Stroganoff is always a favourite in our house anyway. Rich, creamy sauce filled with yummy meat and mushrooms. It’s like a really easy, tasty casserole, that’s a little different. Stroganoff is often served with rice or pasta, but to be honest, I prefer it with potatoes. It’s just so comforting. I often serve it with mash; I love the stroganoff sauce with mash. But, for my Leftover Roast Beef Stroganoff, I tend to go for baby potatoes or any leftover roast potatoes from my Sunday lunch. Just to keep the roast beef feeling going. You could also add some leftover veggies to this Easy Beef Stroganoff.
