Prepare the rendang: (this can be done days before)
Follow this recipe to make beef rendang. You can also do the rendang ayam Padang, rendang ayam Perak. Alternatively, you can always get a rendang seasoning pack if you prefer not to prepare it from scratch. You won't need all the rendang, but I can assure you that you won't be mad with any leftovers
Shred the beef using two forks or any meat shredder tool you have. If you use chicken rendang, remove the meat from the bone and shred them
If you have some frozen rendang stash in your freezer, thaw overnight in the fridge before using
Cook the Pasta
Bring a large pot of salted water to a boil. Add the oil and cook the macaroni until just under al dente (about 2 minutes less than the package recommends). Drain and set aside. Give the pot a quick wash and dry it to make the cheese sauce
Make the Cheese Sauce
Melt the butter over medium heat. Add the flour and cook for 1–2 minutes
It turns lightly golden and no longer raw.
Slowly pour in the milk, whisking continuously until smooth and slightly thickened.
Stir in the shredded cheddar cheese and continue to mix until the sauce is velvety and creamy.
Combine with Rendang and Pasta
Add the cooked macaroni and the rendang (along with some of its sauce) into the cheese sauce. Stir to combine.
The mixture should be slightly saucier than your usual mac and cheese—that's the secret to keeping it creamy after baking. Taste and add salt if needed.
Add more milk if needed. Don't worry about it being a bit too saucy, because after baking, it will be just the right consistency
Toast the Panko
In a small pan, combine the panko, melted butter, and a pinch of salt. Toast over medium heat, stirring constantly, until just lightly golden. This step gives the topping a head start to ensure it stays crispy.
Assemble and Bake
Preheat your oven to 350 F (180 C) for conventional oven. Lower the temperature by 20 F (15 C) if using convection oven.
Lightly butter a 2-quart baking dish. Pour the rendang mac and cheese mixture into the dish and spread it evenly. Sprinkle the toasted panko on top.
Bake for 25–30 minutes, or until the top is golden brown and bubbling at the edges.
Rest and Serve
Let the mac and cheese rest for about 5 minutes before serving. This helps the sauce settle and makes serving easier. Tuck in!
