Ingredients
Onions: Two thinly sliced onions

Beef broth: 1⅓ cups (300ml)
Worcestershire sauce: One tablespoon
Dijon mustard: One tablespoon
Cornstarch slurry: One tablespoon cornstarch mixed with two tablespoons water
Quark cheese: One cup (240g)
Sour cream: Half cup (120g)
Rigatoni pasta: 14oz (400g)
Reserved pasta water: About a quarter cup
Parmesan cheese: Three tablespoons
Flat-leaf parsley: A handful chopped
Leftover roast beef: 1½ cups (350g)
Instructions
Get the pasta going: Cook rigatoni in salted water until al dente, reserve some cooking water before draining.
Start your flavor base: Cook onions in a large pan with cooking spray over medium-low heat for about 5 minutes. Add mushrooms and cook for another 5 minutes.
Build your sauce: Add beef broth and Worcestershire sauce, simmer, then stir in Dijon mustard and cornstarch slurry until it thickens.
Make it creamy: Turn heat to low, add quark and sour cream, stir until smooth.
Add your beef: Fold in leftover roast beef, season with salt and pepper.
Bring it all together: Add cooked rigatoni and reserved pasta water as needed for sauce consistency.
Get ready for the magic: Transfer to an oven-safe dish, sprinkle Parmesan.
Get that golden crust: Broil for about 5 minutes until golden.
Finish with freshness: Sprinkle with chopped parsley and serve hot.
Notes
Don't overcook the pasta, it continues cooking under the broiler.
Sauce too thick? Add reserved pasta water gradually.
If you have leftover beef gravy, add it with the beef for extra flavor.
Avoid boiling the sauce when adding dairy to prevent separation.
Prepare ahead and broil right before serving for quick meal prep.
