Instant Pot Irish Cheddar Bacon Mac and Cheese. Celebrating the Irish today, with a seriously good (and easy) “Irish” Cheddar Pasta. Made completely in the Instant Pot…crisp the bacon, sauté the brussels sprouts, add the pasta shells, butter, and water, and cook for 3 minutes. Then simply stir in some sharp Irish cheddar cheese, and you’re ready to eat. I like to call this the Easiest Mac and Cheese ever. With some bacon on top for extra flavor, and some brussels sprouts mixed throughout for balance, every bite is cheesy, creamy, and perfect.
I’m going to be honest, St. Patrick’s Day really snuck up on me this year. Anyone else? It feels like New Year’s was just yesterday. But then it also feels like New Year’s was a life time ago. It’s been busy and crazy. But after a very productive few days, I’m finally feeling confident and back on my A game. It’s crazy what a couple good days can do for one’s self confidence, I surely needed them! Love ending the week on a strong note, and what could be better than a cozy mac and cheese!
And yes, I do know it’s only Thursday, but we’re so close, and tomorrow’s post is GOOD one too. So I’m just a little excited.
Anyway, in year’s past, I’ve shared many good Irish inspired recipes. Including these 8 ingredient brownies, this over the top Irish whiskey burger, a fun brisket burrito recipe, and even soda bread. But this year it’s all about the instant pot mac and cheese…with some delicious Irish cheddar, bacon, and brussels sprouts too. Why use Irish cheddar? Because it’s extra delicious.
Also because, other than potatoes, corned beef, and Guinness beer, I for the life of me could not think of another good Irish ingredient. Yes, I know they’re out there, and please feel free to share them with me if you happen to be Irish. But the sound of a sharp Irish cheddar mac and cheese just sounded too delicious, so I went for it.
Verdict? It’s really good, really simple, and a new favorite Instant Pot recipe.
If you’ve never had Irish cheddar, you must find some at your grocers and give it a try. Most carry some form of Irish cheddar, it’s just a step above other types of cheddars. Irish Cheddar is made from cows raised in southeast Ireland, also known as the “Garden of Ireland.” Its flavor is buttery with hints of sweetness, and when melted? Ah, it’s the creamiest, most delicious cheese. It’s probably my favorite variety of cheddar, and it’s perfect for a simple mac and cheese.
OK, now on to the mac and cheese details.
First start by crisping up the bacon in the instant pot. I included bacon for a nice salty, rich flavor. I also love the combo of bacon, brussels sprouts, and cheddar. Of course if you’re vegetarian you can simply omit the bacon. Once the bacon is crisp, add the brussels sprouts, and then the pasta, butter, and water. Cook for 3 minutes and let the instant pot do its thing. Release the steam, add some milk, add all that delicious cheese, stir, and DONE!
Instant Pot mac and cheese in under 20 minutes. And honestly, it’s one of the creamiest mac and cheese recipes I’ve created. The cheese adds all the flavor, while the brussels sprouts add a nice touch of green color. It’s indulgent, but not overly so, since we’ve actually made this with way less butter, no flour, and no cream.
So…a kind of healthier mac and cheese? Hey, it’s all about balance.
If you’re not a fan of brussels sprouts, I’d recommend using broccoli or another green vegetable you do love. I think the pop of color is really nice! Or if you don’t do vegetables in your mac and cheese, simply leave the brussels sprouts out!
For those of you who may not own the Instant Pot, I included stove-top directions for you guys too! This recipe is too good not to make, and it would be something fun for St. Patrick’s Day on Sunday. Serve it up as a main, or along side your favorite Irish roast, either way, just make it. I have full confidence you’re going to love this one.
