Mac and cheese is one of the Man’s favorite dishes. I swear, he could eat mac and cheese for every meal of the day and never get tired of it. 

Honestly, what’s not to love about a creamy bowl of mac and cheese?

It’s one of those foods that transports me straight back to childhood. You know the days when your mom would make you a big bowl and you would just sink into the comfort of CHEESE. 

I remember when I was in college and had my first kitchen in a house I shared with a few girls. My grandma had given me a ton of old cookbooks and one of them had a mac and cheese made with a combination of white cheeses. 

I had only grown up with yellow cheeses (cheddar and the like), so let me tell you, my mind was completely blown with these new flavors.

This particular recipe is my grown-up take featuring one of my favorite cheeses – Havarti. 

Castello Creamy Havarti is a mild cheese with a hint of tanginess, which really elevates the mac and cheese. It just so happens to be a killer flavor pairing for the chicken and jalapeño! It’s a cheese that I usually eat on crackers since it’s so creamy and still sliceable, but it can be grated for dishes like this one as well.

If you haven’t tried Castello Cheese before and want to expand your cheese knowledge, any of their cheeses are a great place to start.


Because of their packaging! With one look, you can see the flavor strength of any of their cheeses to tell you how intense the taste experience is based on the flavor, texture and smell. As you can see, Castello Creamy Havarti  is definitely one of the more mild cheeses, making this dish a family favorite for kids and adults alike!

We’re making Havarti mac and cheese!

Make Pasta

Bring a pot of salted water to a boil and cook the shells until they are almost al dente. This should take about 8 minutes, but you can always double check the packaging on the pasta to make sure. 

Once the pasta is done, drain in a colander and place the empty pot back on the stove.

Cook Veggies

While the pasta is boiling away, cook up the veggies! All you need to do is saute the jalapeño and onion in olive oil in a medium skillet with seasoning for about 2 minutes. Then stir in the garlic and cook another minute before setting aside.

Make Sauce

The sauce gets made in the same pot you used for the pasta (less dishes = less mess to clean up later!). Melt the butter, then whisk in the flour cooking until it’s golden brown. Slowly whisk in the milk until it’s thickened, then add 3/4 of the grated Castello Creamy Havarti

When the cheese is melted, add in the veggies, pasta and chicken.

Assemble and Bake

Now we throw it in a casserole dish! Spread it out evenly and then sprinkle over the remaining grated cheese. 

Place in the oven and bake for 30 minutes. The top should be nice and golden brown and the inside should be hot and bubbly. Serve right away!

Got questions?

How spicy is this Havarti mac and cheese?

The jalapeño isn’t too spicy at all! Really, you get the flavor of the jalapeño instead of the heat since the seeds are removed. That means those who hate spicy things will still love this dish. 

If you want to amp up the heat, leave the seeds in and use them in the recipe. I recommend only doing this with one of the jalapenos, unless you really want to light your mouth on fire.

Can I prep this ahead of time?

Generally, I don’t recommend preparing mac and cheese in advance to guarantee that the sauce doesn’t break and get greasy. 

If you really want to, assemble the whole thing, but do not bake it. Cover it and place in the refrigerator for up to 2 days. When you are ready to bake, just throw it in the oven. You will likely have to add on some extra time to the bake because it will be cold.

Can I double the recipe?

Of course! This recipe is fantastic for a party
