Ok. WE NEED TO TALK ABOUT THIS ONE PAN CHICKEN.
Here are the bullet points because I know you’re busy + also we like to keep things organized and efficient here:
- ONE PAN.
- Mushrooms + potatoes + spinach OH MY
- The easiest, creamiest rosemary garlic parmesan sauce (*swoooooon*)
- ONE PAN. Did I say that already?
- Ready in under an hour. Because we have THINGS to do, duh
- Easy to customize – potatoes and sauce are the perfect blank canvas for any protein or veggies you have on hand! Ahhhhh, possibilities.
- Literally LICK-YOUR-PLATE tasty. Example: When I made this for some friends, there was an, ermmm, “conflict” over the last piece (they ended up splitting it. Because ADULTS).
This one pan chicken dinner is simple but hearty, and it’s packed with a great supporting cast (mushrooms! spinach! potatoes! rosemary!)
You could serve this over rice or quinoa if you’d like to stretch it out a bit more, but I honestly love it just as it is – it’s like a warm, cozy, ultra-comforting food hug (which is perfect, because it’s finally sweater weather and I’m craving warm cozy food baaaaaaasically 24/7).
The mild, creamy, slightly starchy texture of white potatoes makes them perfect for this recipe. They also hold their shape well, so even though we’re cooking them for awhile here and then covering them in the creeeeeeeamiest sauce, you’re still going to have well-defined pieces of potato (rather than an accidentally-sort-of-mashed-but-not-in-the-good-way potatoes situation, because yikes).
Also, I don’t know about you, but I almost ALWAYS have potatoes in my pantry – which means recipes like this one are ultra-convenient even when I haven’t had time to go to the store. Just use the potatoes and sauce as a base, and customize this recipe with whatever else you have on hand! (Broccoli, arugula, roasted butternut squash, and cauliflower are some of my favorite additions so far).
ALSO, if you’ve been following Life As A Strawberry for awhile, you’re probably picked up on the fact that I love thickening sauces with a roux, which is basically just a flour-and-butter (or olive oil) combo.
But that doesn’t always work if you’re out of flour or are following a gluten-free diet, so I mixed it up a bit for this recipe and thickened the sauce with cornstarch.
You can totally use a roux here if you prefer, but a quick cornstarch slurry will do the trick just fine. Observe:
An easy one pan chicken and potatoes recipe ready in under an hour.
- 2 Tbsp. olive oil, divided
- 1.5 lbs. boneless, skinless chicken thighs
- salt and pepper to taste
- 1/2 large yellow onion, diced
- 2 cloves garlic, minced
- 1 lb. white potatoes, cut into a large (1/2″ or so) dice
- 8 oz. baby portobello mushrooms, halved (or quartered, if they’re large – you want the mushrooms to be roughly the same size as the diced potatoes!)
- 2 sprigs fresh rosemary, leaves removed from stems and roughly chopped
- 1 cup chicken stock
- 1/4 cup heavy cream
- 1 Tbsp. cornstarch
- 2 cups fresh spinach, roughly chopped
- 2/3 cup shredded parmesan cheese
- Heat oven to 400 degrees F.
- Heat half of the olive oil over medium-high heat in a large oven-safe pan (I use a 10-12″ cast iron skillet, but a dutch oven or large flat-bottomed skillet work too)
SEAR THE CHICKEN:
- Season chicken thighs on all sides with salt and pepper.
- Gently add chicken thighs to the hot skillet and sear for 2-3 minutes per side until you have a nice, slightly brown crust. Don’t worry if they’re not fully cooked – they’ll finish cooking in the oven.
- Remove seared chicken thighs to a plate and set aside. Return the skillet to the stove.
MAKE THE SAUCE:
- Add the remaining olive oil to your skillet and turn the heat to medium.
- Add onion and garlic to skillet and sauté 2-3 minutes until onion has softened.
- Add diced potatoes to skillet and stir to combine. Cook another 2-3 minutes until potatoes have softened and developed some color.
- Add mushrooms to skillet and give everything a stir. Cook another 2-3 minutes until mushrooms have softened and reduced in size.
- Add the chopped fresh rosemary and another pinch of salt and pepper to taste. Stir to combine.
- Add chicken stock to pan a little bit at at time, stirring well between each addition to scrape off any browned bits from the bottom of the pan (that’s where the flavor is!)
- Add the heavy cream to the sauce and stir to combine.
BAKE IT ALL UP:
- Return the seared chicken to your skillet, nestling each piece into the sauce.
- Place the skillet in your hot oven and bake for 15-20 minutes until potatoes and chicken are each cooked through.
THICKEN & FINISH THE SAUCE:?
- Remove skillet from oven.
- Spoon 2-3 tablespoons of sauce out of the skillet (careful, it’s hot!) and into a small bowl or measuring cup.
- Add cornstarch to bowl and whisk to combine. This is your cornstarch slurry.
- Slowly add cornstarch slurry back to skillet a bit at a time, stirring to combine. It can take a minute or two to thicken up – you may not even need the whole slurry, so just keep an eye on it!
- Add spinach and parmesan cheese to sauce and stir until cheese is melted. Garnish with an extra sprig of rosemary (optional) and serve immediately.
This looks like a lot of steps, but I promise it isn’t too complicated! I made the recipe instructions a little longer because I wanted you to be able to see the order of operations at a glance.
I used chicken thighs for this recipe because it’s what I usually have on hand, but you can use any cut of chicken you like! I’d recommend sticking with skinless because the skin can get rubbery when it sits in the sauce too long, but you could use bone-in thighs, chicken breasts, or anything else you have on hand!
Use a roux instead of a cornstarch slurry to thicken this sauce if you like. I recommend a roux of 2 Tbsp. butter and 2 Tbsp. flour just before you add the chicken stock.
Lighten this dish up by substituting milk or additional chicken stock for the heavy cream.
Use any veggies you like here! Broccoli, arugula, peppers, cauliflower, and roasted butternut squash are all great additions.
Use fresh thyme instead of rosemary if you like, or substitute 1/2 tsp. dried rosemary for the fresh leaves.
Shred your own parmesan cheese for this recipe – store-bought shredded cheese often has additives that prevent it from melting smoothly.
The exact consistency of your sauce can vary, and everyone has different preferences, so don’t worry if it doesn’t look perfect yet! Try one of these tricks?to adapt the sauce to your liking:?If you’d like a thicker sauce, make a bit more cornstarch slurry. If you’d like more sauce, you can increase the amount of chicken stock in the recipe. Less sauce? Decrease the amount of stock and cream. To thin the sauce out, add an extra splash of stock or milk.
