High Protein Chicken Pasta Bake

High Protein Chicken Pasta Bake. Easy meal prep idea

Yes, it’s still 100 million degrees in Texas right now but there’s just something about being 8 months pregnant and it finally being the end of August that has me craving all the comfort foods. We first made this high protein chicken pasta bake two weeks ago and I haven’t been able to get it off my mind. I had to make it again. With more portions. And more veggies!

Two things I love about this recipe:

  1. It’s not super complicated.
  2. It’s super affordable (~$25 for the entire dish, and makes a bunch of servings.

The best way I can describe it is part-mac and cheese, part veggie bowl.

First up, the cheese sauce. Onions are sautéed in butter, then baby portabella mushrooms and garlic is mixed in before we move to the traditional base of a mac and cheese – flour, butter (from the onions – no more is added), milk, and cheese. We’re lightening up that mix with a little chicken broth, too.

In a separate pot, you make protein pasta and right as the pasta is almost done, toss in broccoli (or other veggie of choice – asparagus would be delicious too!) to quickly blanch before straining it all.

Mix the two together and add in two pounds of chicken, then bake, top with more cheese, and bake a little more.

The macros (using Fair Life Skim) came out to 13f / 26c / 27p (320 calories) per 300g serving (12 portions). If desired, you could cut down on the fat by using less butter and less cheese, or increase the protein by adding more chicken.

Easy, right? Did I mention it makes 8-12 servings, pending size? Scroll for the full recipe + instructions for this high protein chicken pasta bake.
