This filling Greek Garlic Chicken with Roasted Potatoes & Creamy Mushroom Pesto blends earthy mushroom richness with classic Mediterranean tastes for a knockout dinner. The juicy chicken soaked in herbs goes great with crunchy potatoes and a special pesto that makes this way better than your usual weekday meal.
I came up with this dish when I needed to use cremini mushrooms before they went bad, and now my family asks for it all the time. My mushroom-hating husband cleans his plate whenever I make it.
Ingredients
- Boneless skinless chicken breasts they soak up all the Greek seasonings and work as the main protein
- Fresh oregano and dried thyme these Greek-inspired herbs really transform your ordinary chicken
- Yukon Gold potatoes they get super crispy outside but stay soft inside when roasted
- Fresh rosemary brings wonderful pine-like aroma that works so well with the garlic
- Cremini mushrooms they've got a richer taste compared to regular white mushrooms
- Fresh basil leaves adds a fresh pop that cuts through the rich mushroom pesto
- Heavy cream makes the pesto incredibly smooth and helps it stick to the chicken
Step-by-Step Instructions
- Marinate the Chicken
- Mix olive oil, garlic, lemon juice, oregano, thyme, salt and pepper in a container. Coat sliced chicken breasts thoroughly in this mixture. Let it sit for at least 15 minutes while you work on the other parts. The lemon juice works on making the meat tender while all those herbs and garlic sink into the chicken.
- Roast the Potatoes
- First thing, turn your oven to 425°F. In a big bowl, mix potato chunks with olive oil, fresh garlic, rosemary and seasonings until they're all covered. Spread them out on a baking sheet with plenty of room between pieces. Don't crowd them or they'll steam instead of getting crispy. Cook for 20-25 minutes and flip them halfway, until they're golden outside and soft inside.
- Cook the Chicken
- Get a skillet really hot before adding your chicken. This locks in all the good stuff. Each chicken piece needs about 3-4 minutes per side until they're cooked through with nice brown marks. Don't leave them too long since thin slices cook fast. Let them rest a bit after cooking.
- Create the Mushroom Pesto
- Cook mushrooms and garlic in olive oil on medium heat until they shrink down and turn golden brown. This lets all their flavor come out. Put this mix in a food processor with basil, Parmesan, cream and a squeeze of lemon. Blend until it's mostly smooth but still has some texture. Give it a taste and add more salt or pepper if needed.
- Assemble the Dish
- Start with a bed of those crispy potatoes on each plate. Put your chicken slices on top to build some height. Pour the creamy mushroom pesto all over everything so it runs down the sides. The hot chicken will warm the pesto and make everything look amazing.

That mushroom pesto really makes this dish special. I found it by chance during a rainy weekend when I was just using what I had in my pantry. My daughter who usually avoids mushrooms now asks for this "special green sauce" all the time, which feels like a big win as a parent.
Storing and Reheating
This meal stays good in the fridge for up to three days in sealed containers. The flavors actually get better over time, so it's perfect for planning ahead. To reheat, just cover with foil and warm in a 325°F oven for about 15 minutes until hot. You can use the microwave if you're in a hurry but it might make the chicken a bit tough. I often make extra pesto and freeze it in ice cube trays to add quick flavor to other meals later.
Smart Substitutions
Chicken thighs work great if you like dark meat, and they stay juicier when reheated. For a no-meat option, try thick slices of roasted portobello mushrooms instead of chicken. They soak up marinade really well and have a meaty feel. You can swap in red potatoes for Yukon Golds, though they won't be quite as buttery. The pesto tastes different but still works with spinach or kale instead of basil if you want to change up the nutrients and flavor.
Serving Suggestions
This dish stands on its own, but goes really well with a basic Greek salad dressed with olive oil and lemon. For bigger appetites, serve it over lemony orzo or with warm pita bread to soak up the extra pesto. It pairs wonderfully with a light white wine like Assyrtiko from Santorini that matches the Mediterranean flavors. When hosting friends, put everything on a big platter with fresh lemon wedges and sprinkle extra herbs on top for a wow factor.
Common Queries
- → How do I ensure the chicken stays flavorful and moist?
Let the chicken soak for at least 15 minutes in a mix of olive oil, garlic, lemon juice, oregano, and thyme. Cook it on medium-high heat and don't leave it too long on the heat to keep all the juices inside.
- → Can I use a different potato variety?
Sure thing, you can swap Yukon Gold potatoes for baby potatoes, red ones, or even sweet potatoes. Just watch the cooking time as smaller ones will get done faster.
- → What can I use as a substitute for heavy cream in the pesto?
For something lighter, try Greek yogurt, coconut cream, or just throw in some extra grated Parmesan cheese to get that creamy feel.
- → How do I store leftovers?
Keep the chicken, potatoes, and sauce in different sealed containers in your fridge. When you want to eat them again, warm up the chicken and potatoes in your oven or in a pan, and use the sauce either cold or slightly warmed up.
- → Can I make this dish ahead of time?
You bet! Soak the chicken and mix up the sauce a day before. Then just cook the potatoes and chicken right before you want to eat for the best taste and texture.
