How Long To Bake Mac And Cheese At 400?

For an oven at 400 degrees, you only need to bake your mac and cheese for 20 minutes! Since most of the components are already cooked before putting it in the oven, it doesn’t need much time in the oven, since you mostly just want to get the crunchy cheese top and melted cheese inside.

What are other temp to cook mac and cheese in the oven?

You can also choose to lower the temp to around 350-375 degrees. At 375 degrees, you can cook the mac and cheese in the oven in 30 minutes. However, there will be lesser crisp on your cheese top and your macaroni will turn out more moist.  If you don’t like any crispy, then 350 degrees will be the better option. Cooking mac and cheese at 350 degrees in the oven takes 45 minutes. Based on experience though, I prefer 400 degrees because it’s faster and more efficient! And I get a crispy cheese top. Though, you also can’t go beyond 400 degrees because that will risk burning your cheese.

1 Boil macaroni

To make mac and cheese, all you need to do is to first boil your macaroni pasta for 8-10 minutes or until it becomes al dente. You can also refer to the packaging instructions to have the exact time (This is originally elbow macaroni, but you can also use penne or pennette if you like!). Then, simply drain your pasta and set it aside!

2 Prepare the cheese layer

Now, you just have to use a skillet and whisk together flour, butter, and milk until it thickens. Once it thickens, just fold in your cheese! I use cheddar for this, but you can also use other types of cheese you want to use!

3 Add seasoning for your mac and cheese.

Then, allow your cheese to melt while you season it with salt, pepper, thyme, dry basil, oregano, and other seasonings you want to add! Once you’re satisfied with your sauce, simply remove it from heat and stir in or fold in your cooked pasta! Make sure to mix it well with the sauce!

4 Bake

Then, transfer that to a baking pan and pop it in the oven for baking! And, you’re done! The classic mac-and-cheese is simple and easy, yet it will amaze you once it reaches your taste buds!

How to cook macaroni and cheese easy?

Macaroni and cheese is just perfect in every sense! While it’s quick and easy, I’m sure your guests can’t wait much longer for your pasta dish to be served! SO, if you need to cut some of the prep time and serve plates faster, here’s what you can do.

Stove-top only

Some recipes skip the oven baking part to save time. This is okay too since your pasta’s already done the moment you mix it with the sauce! So, if you’re in bad need of more time, you can skip the baking part! (If you still want to melt the cheese on top, you can blow torch that part if you have one.)

Prep early and Refrigerate

You can make your mac and cheese ahead of time! Around a few hours before the actual dinner, you can already make your mac and cheese and put it in the pan, then, refrigerate it! Just put it back out when you’re already about to cook, to serve it hot and fresh!

Try One-pot

You can also choose to cook your mac and cheese the one-pot way wherein you only use one pot for all your components! This can make things faster as you’re only working on one pan or skillet.
