Healthy Roasted Red Pepper Alfredo

This Healthy Roasted Red Pepper Alfredo is a delicious lightened up Alfredo. Made without heavy cream, this lightened up sauce still manages to be creamy and decadent!

Alfredo sauce has always been my weakness! I am naturally drawn to all things with a creamy texture and so this doesn’t come as a shock to anyone who knows me. While Alfredo is probably one of my favourite sauces, I don’t indulge in it as often as I’d like to at restaurants. While I love the creamy, decadent taste, I’m put off a bit by just how much butter and cream goes into making a rich sauce.

Enter homemade version!

I love making lightened up versions of my favourite dishes (no surprise there)! This Alfredo is definitely one of my favourite lightened up sauces for sure.

I use the term Alfredo lightly here. As it’s not made with a stick of butter or heavy cream, I hesitated label this an Alfredo sauce as die-hards might be offended. Oh well, I am calling it just that because that is the sauce that inspired this dish! Except, of course, by the addition of roasted red peppers.

Why add roasted red peppers? Flavour of course! While I am not a huge fan of most peppers, when they are roasted they are absolutely irresistible! Roasted peppers brings out their natural sweetness and enhances their flavour.

You can easily roast your own peppers and use them in this sauce but in the interest of making this a super-easy weeknight dinner, I chose to use jarred peppers instead. Why not keep things a bit easier?

I often serve Healthy Roasted Red Pepper Alfredo with spaghetti or other long noodles like linguine or fettuccine. I love twirling the noodles around my fork as I eat them. Feel free to change things up with any pasta you prefer! Penne and bowtie pasta work well here too!
