Hi there! Jess in the Rada Kitchen, thanks for joining me. Today we are going to make a one pan chicken and veggie dish. This is our rosemary spinach and portabella mushroom bake. We are going to start by prepping our chicken.

For our chicken I have some boneless skinless here. I am just going to come in and section this off into smaller pieces, about medallion sized portions. This will make sure that we have even cuts and that it cooks all the way through. And then we can trim the fat and the little bit of skin that is left.

So in the bottom of my Rectangular Baker I’m going to add some grapeseed oil. You can use extra virgin olive oil. If you wanted to make this dish a little richer and don’t care so much about the fat content, you can actually use some melted butter. But we’re going to lighten things up here. I’m going to layer all this chicken in and we’re going to season it up before we add all of our other ingredients.

OK, for my seasoning I’m using Rada’s Burger & Fry Seasoning, just as my season all. And then I have some dried thyme, flip it over and do it again. We’re going to top it off with a little bit of fresh cracked pepper. Let’s go ahead and make our sauce for our chicken and veggies. Here we have some chicken stock. Some milk. Fresh chopped garlic. I have three cloves worth. Some white wine and i’m using a chardonnay for this. Some sea salt. And we’re ready to whisk in our flour as our thickening agent.

So here we have some fresh rosemary that smells amazing. We’re just going to take it off the sprig here and we’re going to do a rough chop on it. With my Rada French Chef knife we’ll just come on in. We are going to top our chicken with our fresh chopped rosemary. I’m going to save just a little bit to garnish on top of our cheese at the end when it’s done baking.

Now we’re going to add our veggies. So, we have four cups of sliced portabella mushrooms. We’re just going to go ahead and dump these on top. We’re kind of going to layer the spinach so we get a nice, even coating of all this yummy stuff. So I have half a bag or about two cups of spinach. I’m just going to tear it up a little bit. You can use baby spinach as well. We know this is going to shrink down a ton when it bakes.

Let’s get the other half of our mushrooms on. Now we’re ready to pour on our sauce. Just give it one more whisk with our Rada Handi-Stir. Right on top it goes. This is going to thicken up once that heat hits it. Now I used a low-fat milk in here, but, like I mentioned before, if you wanted to do the whole, decadent richness, you can just use heavy cream. So now we’re going to top this with cheese like mozzarella. I’m using Monterrey Jack cheese because I think it melts a little bit better. We’ll do the whole bag on there. And just arrange it. Last up, you’re going to top it off with that fresh chopped rosemary. And into an oven at 400 degrees for about 40 to 45 minutes.

So here we have fresh out of the oven our baked chicken topped with all that delicious cheese. This is a great low-carb dish, and as you saw, it can be ready in no time.
