The End of the Stupid Hot South Louisiana Summer Called For This Easy Gluten Free Dinner Recipe. Yep. 

The last few weeks have been pure torture down here, y'all!! One hundred degree temperatures, with humidity as high as the Throne of Heaven!! We've been hot. We've been sweaty. And we've been all kinds of sticky after being outside for just a few minutes. 

And I've been sneaking into my closet lately, literally cleaning the dust off of my boots. Waiting, hoping, praying for our soon return to calming, cooling weather. And eyeing my favorite sweaters and long-sleeved shirts. And lingering WAY too long in my air conditioned closet for the blessed hope of the end-of-south-Louisiana-summer-relief. Yep.

I loved, loved, loved eating my cold summer salad treats. But, my heart knows that its now time to get back to the business of eating my favorite comfort foods, too. So, I broke out my current favorite cast iron skillet. And I used what I had on hand in my fridge and freezer to create this best ever gluten free cheesy chicken broccoli pasta. 

And it was sooo good that we ate it all up before I could even snap a shot!! So, I just HAD to make another batch of this gluten free cheesy chicken broccoli pasta that would actually get photographed and presented to you for your delicious dining enjoyment, too!! 🙂

How to Make the Best Ever Gluten Free Cheesy Chicken Broccoli Pasta Easy and Breezy...

Start the best ever gluten free cheesy chicken broccoli pasta by making a quick, 5-minute marinade for the cubed chicken tenders. Then, steam fresh or frozen broccoli florets, and set aside. (I used the microwave to steam frozen broccoli florets.)

You'll also want to boil water, and cook your gluten free penne pasta to al dente. 

Next, brown the Cajun trinity of onion, bell pepper and celery in a cast iron skillet. Add the chicken, and cook down until lightly browned. Then, add garlic during the last few minutes of cooking time. Do NOT drain, cause it's all going to come together perfectly, trust me!!

Now, make a blond roux by mixing butter or oil with a bit of tapioca flour in a separate saucepan:

Then, scoop up a few tablespoons of the veggie/chicken pan drippings:

And stir them right into the blond gluten free roux:

Add milk and cheeses:
