This looks like a creamy heart attack on a plate doesn’t it?

Oh, but it’s soooo not.

Which means you can shovel forkful after forkful of delicious pasta into your mouth without that nagging feeling in the back of your mind about how bad of a decision it is.

Alfredo sauce is that restaurant dish that haunts you.

It’s the thing you know is absolutely horrible for you when you’re staring at the menu but your brain refuses to let go of the idea of the delicious creamy sauce.

So, you throw caution to the wind, order the butter and cream laden dish and then before you know it you’re shoving half the contents of the bread basket down your throat and ordering tiramisu for dessert since you’ve completely thrown any attempts of healthy eating out the window for the night anyway.

This healthier take on spaghetti alfredo is filled with broccoli and won't bust your diet.

It happens. Right?

Please say it’s not just me?

The alfredo bug bit me hard yesterday and before I knew it, things were coming out of the pantry and fridge and I was determined to show the sauce who’s boss with this healthy spaghetti alfredo.

This lightened up spaghetti alfredo comes together in under just 20 minutes for an easy, healthy dinner.

See that measly 1 tablespoon of butter? That’s it for the “bad stuff” in this recipe.

Total creaminess achieved and barely a dent in my butter stash.

Good for the wallet and for your heart.

The rest of the creaminess comes from a combination of low fat milk, cream cheese and parmesan. Needing heavy cream or half and half for that alfredo taste is a total myth, don’t be fooled!

From prep to roux to finished product this whole thing takes under 20 minutes.

Creamy, cheesy and super decadent, you'll never know this lightened up spaghetti alfredo is a healthier spin on the classic pasta dish.

Beats the restaurant wait and there’s no bread basket or dessert menu to tempt you.

Swap out a gluten-free pasta to make this dish gluten friendly. This post on the best brands of gluten-free spaghetti is a great resource!

This is a favorite recipe of mine! The only tweak I make is don't use flour. I found it was way to thick with the flour.
