I got a request from Nelson (a BB reader) last week to make some homemade mac and cheese, and what a fantastic idea it was. I really need some mac and cheese in my life right about now. Of course, I added a good dose of broccoli to sort of balance out the meal and make sure I get my greens. ;) And I ended up using shells instead of macaroni because that’s what I had on hand. But if you don’t want broccoli shells and cheese, just leave out the broccoli, make everything else as directed, and you’ll have a good classic shells and cheese.

The Cheese Sauce Method

Making a cheese sauce can be a little bit intimidating at first, but give it a shot. Once you get the hang of it, it’s super easy. The thickening action of the roux is kinda like magic; very mysterious but you gotta learn to trust it. It will thicken.

What Kind of Cheese to Use

Sharp cheddar will give your mac the most flavor, but it also tends to “break” the easiest (turn lumpy in the sauce), so I usually use medium cheddar. I also added a little parmesan (another strong cheese) because after tasting the sauce I wanted it even cheesier! I despise a bland macaroni and cheese.

Why Add Hot Sauce?

I add just a little bit of hot sauce to my shells and cheese to add flavor but not really any heat. The hot sauce is completely optional. Many people add dry mustard which has a similar effect on the flavor. It just gives it a nice little zing of flavor on the back end. In the end, the cheese sauce is all about tasting and adjusting it to your liking. And really, who’s complaining about repeatedly tasting cheese sauce? No one.

Instructions 

  • Bring a large pot of water to a boil for the pasta. Once boiling, add the pasta and continue to boil until the pasta is tender. Drain the pasta in a colander and set it aside until ready to use.
  • Meanwhile, allow the broccoli to thaw. Once partially thawed, chop the florets into smaller, bite-sized pieces, and set them aside to fully thaw while you prepare the rest of the dish.
  • While the pasta is cooking, begin the cheese sauce. Finely dice the onion and add it to a sauce pot with the butter. Cook the onion and butter over medium heat until the onions are softened (about 2-3 minutes).
  • Add the flour to the butter and onion. The flour and butter will form a paste, or roux. Whisk the roux over medium heat for 1-2 minutes more taking care not to let it scorch. This slightly cooks the flour preventing the cheese sauce from having an overly flour or paste-like flavor.
  • Whisk the milk into the roux until no lumps remain. Add some freshly cracked pepper to the sauce. Bring the mixture up to a simmer, stirring often (you may need to raise the heat just slightly). When the sauce reaches a simmer, it will begin to thicken. When it is thick enough to coat the back of a spoon, it’s time to add the cheese.
  • Turn the burner off and whisk in the shredded cheddar, one handful at a time, until it is fully melted in. Next, stir in the grated Parmesan. Give the cheese sauce a taste and add salt, pepper, and hot sauce to taste.
  • Once you have the cheese sauce seasoned to your liking, return the drained pasta to its large pot, add the chopped broccoli, and pour the cheese sauce over top. Stir until everything is combined and coated in the wonderfully cheesy sauce. Serve hot.

Notes

*To use fresh broccoli in this recipe, cut two broccoli crowns into small florets. Add the cut florets to the boiling pasta water during the pasta’s last minute of cooking. This will blanch the broccoli, but leave it just firm enough to add texture. Drain the broccoli along with the pasta in the colander.

How to Make Broccoli Shells and Cheese – Step By Step Photos

Top view of a bowl of Shredded Cheddar cheese

Shred one 8oz. block of cheddar. Just be aware that sharp cheddar tends to “break”, or become lumpy, in cheese sauces a little bit easier than medium or mild cheddar. So, if you’re new to cheese sauces, start with a medium or mild cheddar.

Frozen Broccoli Florets being chopped on cutting board with knife

Allow 1/2 lb. frozen broccoli florets to thaw. Once they are thawed enough to cut, chop them into smaller, bite-sized florets. Set them aside until ready to use (and to allow them to fully thaw).

Pot of water with raw shell noodles in it


Bring a large pot of water to a boil for the pasta. Once boiling, add 8oz. pasta shells and continue to boil until the shells are tender. Drain the shells in a colander.

Onions and Butter in pot

While the pasta is cooking, prepare the cheese sauce. Finely dice 1/2 of a small onion (about 1/2 cup diced). Add the diced onion to a saucepot with 3 Tbsp butter. Cook the onion in the butter over medium heat until the onions are soft and transparent.

Flour added to onion and butter to create roux, mixed with whisk


Then add 3 Tbsp all-purpose flour. Whisk and cook the flour with the butter and onions for about 2 minutes. This will slightly cook the flour and prevent the sauce from having a floury or glue-like flavor. This paste-like flour and butter mixture is called a “roux” and is what will thicken the cheese sauce.

Whisk in Milk to roux mixture

Whisk in 2.5 cups whole milk until there are no lumps. Also, add some freshly cracked pepper (5-10 cranks of a pepper mill). Continue to cook and stir the milk until it comes up to a simmer, at which point it will begin to thicken.

When the sauce is thick enough to coat the back of a spoon, it is time to add the cheese. 

Cheddar cheese being added to pot with cheese sauce

TURN OFF THE HEAT, then stir in the cheddar, one hand full at a time, until it is fully melted into the sauce. It’s important to remove the sauce from the heat and melt in the cheese slowly to prevent the sauce from “breaking” or turning lumpy.

Parmesan being sprinkled into cheese sauce mixture

Once all the cheddar is melted in, stir in 1/4 cup grated Parmesan.

Hot sauce being poured into cheese sauce mixture


It’s now time to taste and season. I added a few dashes of hot sauce and just a little salt. You can use any hot sauce you like, Tobasco, Franks, Cholula, Sriracha, whatever. The idea is to add just enough to give the sauce a little zing, but no heat.

Pouring cheese sauce over cooked noodles and broccoli in pot


Once the sauce is seasoned to your liking, return the drained shells to the large pot, add the chopped broccoli, then pour the cheese sauce over top.

  1. Lilo, if you’re looking to cut salt but want the salty flavor, try Nori flakes. They are flakes of seaweed wrappers, which have a naturally salty flavor. Seaweed is really good for you and when flaked will add a nice salty touch without the sodium. It’s relatively inexpensive if you order online, too.

  2. This looks absolutely amazing and I can’t wait to try it! Adding broccoli to mac and cheese is a stroke of brilliance. :D

  3. A friend of mine turned me on to your sight and so far I’m loving it. I notice that you do end up using salt often which I’ve been trying to cut out. If it’s something you enjoy, I’ve found a little bit of ginger (I always have ginger paste on hand, but you can mince fresh ginger if you want) gives me the extra flavor I’m looking for without the extra salt. :)

  4. Just want to say I tried this recipe last night, and I 1/2ed it because I was making just for myself. It was so easy and very delicious! I used skim milk,whole grain pasta, and reduced fat sargento shredded sharp cheddar. I also only had a red onion and not white but it worked just as well, I reduced the amount I diced up though because the flavor was so strong. You are my new favorite blogger!

  5. Hmmm, any cheddar should work. Was your milk thickened before you tried to whisk in the cheese? I do know (from experience, unfortunately) that if you just try to stir cheese into hot milk it will just clump up on your spoon or whisk. That’s weird that it didn’t melt upon touching the hot, thickened milk. I’ll research it more later today and report anything I find.

  6. Just tried making this tonight for dinner but not sure what went wrong. My cheddar cheese was clumpy and never melted. Are you suppose to use a specific type of cheddar cheese?

  7. I love mac and cheese with a tempered egg in it, but alas I rarely do it slow enough to make sure it won’t scramble.

    But do it right! Throw it in a casserole dish with some panko and cheese on top so it gets a crispy top and a gooey center.

  8. This is an awesome recipe! I love adding broccoli to my mac and cheese, plus broccoli is a great healthy addition to mashed potatoes too.

  9. You never cease to amaze me with your creations. Can’t wait to make this, mac and cheese is my all time favorite food!

  10. This looks wonderful! I love the idea of adding broccoli to the mac & cheese. If I might make a small suggestion of using Gruyere in addition to sharp cheddar cheese. It really adds a lot of richness and flavor though it can be expensive to purchase.

  11. Oh yum! Being from the south, we do love our Mac ‘n Cheese! I’m looking forward to trying your version, including the broccoli since I am a veggie fiend, too.
    Peace & Love,
