What Kind of Chicken Should I Use for Chicken and Garlic Gravy with Cheesy Mashed Potatoes?

You really can’t go wrong with your choice of chicken here—it all comes down to your personal preference. I typically go with boneless skinless chicken thighs because they stay juicy, soak up flavor beautifully, and cook evenly in the skillet. But if you’re a fan of leaner meat, chicken breasts are a fine alternative—just be careful not to overcook them.

For something more rustic and traditional, bone-in, skin-on chicken thighs or drumsticks add incredible flavor to the gravy, thanks to the rendered fat and slow cooking. Just remember they’ll take a bit longer to cook through. If you're cooking for a crowd or want extra flavor, a whole cut-up chicken roasted first and finished in the gravy is downright indulgent.

Options for Substitutions

Whether you're accommodating dietary needs or just working with what's in the fridge, this recipe is easy to adapt:

• Dairy-Free Mashed Potatoes: Swap out the butter and cheese for plant-based alternatives like vegan butter and shredded dairy-free cheese.
• Low-Carb Option: Use mashed cauliflower instead of potatoes—it’s surprisingly satisfying with the garlic gravy.
• Vegetarian Version: Use pan-fried tofu or seared mushrooms instead of chicken and opt for vegetable broth in the gravy.
• Different Cheeses: While sharp cheddar is my go-to for the mashed potatoes, mozzarella, Gruyère, or even cream cheese work beautifully.
• Gluten-Free: Use cornstarch or a gluten-free flour blend to thicken the gravy instead of all-purpose flour.
• Broth Substitution: No chicken broth? Beef or vegetable broth will do in a pinch—just keep in mind it will slightly alter the flavor.

Ingredients for Chicken and Garlic Gravy with Cheesy Mashed Potatoes

Each ingredient in this dish has a job to do, and together, they create layers of comforting, rich flavor.

• Chicken Thighs or Breasts: These are the protein stars—tender, juicy, and perfect for soaking up that garlic gravy.
• Garlic (lots of it!): Roasted or sautéed, it infuses the gravy with a deep, aromatic flavor that defines the dish.
• Yellow Onion: Adds sweetness and body to the gravy as it caramelizes in the pan.
• Chicken Broth: This forms the base of the gravy, delivering savory depth and bringing all the flavors together.
• Butter: Used in both the gravy and mashed potatoes, it brings richness and silkiness.
• All-Purpose Flour: Essential for thickening the gravy without making it too heavy.
• Yukon Gold or Russet Potatoes: These mash up creamy and smooth, perfect for holding all that cheesy goodness.
• Cheddar Cheese: Sharp cheddar melts right into the potatoes, adding a tangy richness that makes them irresistible.
• Milk or Heavy Cream: Used in the mashed potatoes to create that ultra-creamy texture.
• Salt & Black Pepper: Seasoning essentials that bring everything into balance.
• Fresh Parsley (optional): A sprinkle on top adds color and a touch of freshness to finish the dish.

Step 1: Sear the Chicken

Start by seasoning your chicken thighs or breasts generously with salt and black pepper. In a large skillet, heat a tablespoon of butter or oil over medium-high heat. Sear the chicken on both sides until golden brown—about 4–5 minutes per side. You’re not cooking it all the way through yet, just building that delicious crust. Once browned, remove the chicken and set it aside.

---

Step 2: Build the Garlic Gravy

In the same skillet, reduce the heat to medium. Add another tablespoon of butter, then toss in the finely chopped onion. Cook until soft and slightly caramelized, about 5 minutes. Stir in the minced garlic and cook for another minute—don’t let it burn!

Sprinkle in the flour and stir constantly for 1–2 minutes to make a roux. Slowly pour in the chicken broth, whisking to keep the mixture smooth. Let it simmer until slightly thickened.

---

Step 3: Simmer the Chicken in the Gravy

Return the browned chicken to the skillet, nestling it into the garlic gravy. Cover and let it simmer on low heat for 15–20 minutes, or until the chicken is fully cooked and tender. The gravy should thicken further and coat the chicken beautifully. Taste and adjust seasoning if needed.

---

Step 4: Make the Cheesy Mashed Potatoes

While the chicken simmers, boil peeled and chopped potatoes in salted water until fork-tender—about 15 minutes. Drain, then mash with butter, milk (or cream), and shredded cheddar cheese. Keep mashing until smooth, creamy, and rich. Season to taste with salt and pepper.

---

Step 5: Bring It All Together

Spoon a generous scoop of cheesy mashed potatoes onto each plate. Top with the tender chicken and drizzle that rich garlic gravy all over. Sprinkle with fresh parsley for a pop of color, and serve hot.

How Long to Cook Chicken and Garlic Gravy with Cheesy Mashed Potatoes

Timing can make or break a dish like this, but don’t worry—it’s incredibly forgiving.

• Searing the chicken: 8–10 minutes total (4–5 minutes per side)
• Cooking the gravy: About 10 minutes, including building the roux and simmering
• Simmering the chicken in gravy: 15–20 minutes, until the chicken is fully cooked and tender
• Boiling potatoes: 15 minutes, depending on the size of your chunks
• Mashing and mixing: 5 minutes

So from start to finish, you’re looking at roughly 45–50 minutes for the entire dish—just enough time to make it feel special, but still doable on a busy evening.

Tips for Perfect Chicken and Garlic Gravy with Cheesy Mashed Potatoes

• Use warm milk or cream in the mashed potatoes. Cold liquid can cause them to seize and turn gluey.
• Don’t rush the roux. Let the flour cook for a full minute or two before adding broth—it gives the gravy a nutty, developed flavor.
• Deglaze the pan. Scrape up all those brown bits after searing the chicken—they’re flavor gold.
• Choose the right potatoes. Yukon Golds give you creamy mashed potatoes with a natural buttery flavor, while Russets will be fluffier.
• Shred the cheese yourself. Pre-shredded cheese often contains anti-caking agents that prevent smooth melting.
• Let the chicken rest. After simmering, give it a few minutes off the heat before slicing—this keeps the juices inside.
• Season as you go. Taste the mashed potatoes and the gravy before serving. A pinch of salt or cracked pepper can really lift the whole dish.
• Make it ahead. You can prepare both the mashed potatoes and the gravy a day ahead and reheat gently—great for meal prep or holidays.

Watch Out for These Mistakes While Cooking

Even with a recipe as cozy and straightforward as Chicken and Garlic Gravy with Cheesy Mashed Potatoes, a few missteps can take it from dreamy to disappointing. Here’s what to watch out for:

• Overcooking the Chicken: Chicken breasts especially can dry out if left simmering too long. Use a meat thermometer if needed—165°F (74°C) is your sweet spot.
• Skipping the Roux Step: Adding broth before the flour has cooked can lead to lumpy, raw-tasting gravy. Give it time to cook out.
• Undersalting the Potatoes: Potatoes need generous seasoning, especially with cheese. Taste before serving and adjust.
• Burning the Garlic: Garlic turns bitter fast when it’s overcooked. Add it after the onions soften and stir constantly.
• Using Cold Dairy in Mashed Potatoes: Cold butter and milk can cause the mash to seize up and become dense or gluey. Warm them up for a smoother finish.
• Not Scraping the Pan: The browned bits after searing the chicken are packed with flavor. Deglaze with broth and work them into your gravy.

Frequently Asked Questions

What kind of cheese works best in the mashed potatoes?

I usually go for sharp cheddar because it adds a bold, tangy flavor that doesn’t get lost in the creaminess. But mozzarella, Gruyère, or even Parmesan can work beautifully depending on your taste.

---

Can I make this dish ahead of time?

Absolutely. You can prepare both the chicken with gravy and the mashed potatoes a day in advance. Reheat them gently with a splash of milk or broth to bring them back to life.

---

Can I use rotisserie chicken instead?

Yes, rotisserie chicken is a great shortcut. Just skip the searing step and stir the shredded chicken into the finished gravy to warm through.

---

How do I keep mashed potatoes from getting gluey?

Don’t overmix and avoid using a food processor. Mash by hand or with a ricer, and make sure your butter and milk are warm before mixing them in.

Can I use garlic powder instead of fresh garlic?

Fresh garlic really shines in this dish, but if you’re in a pinch, you can use 1 teaspoon of garlic powder per 3 cloves of fresh garlic.

How do I thicken the gravy if it’s too thin?

Let it simmer uncovered a bit longer, or stir in a slurry of 1 teaspoon cornstarch mixed with 1 tablespoon cold water and cook until thickened.

---

Can I add vegetables to the gravy?

Yes! Mushrooms, peas, or spinach can be added after the gravy is built and before you simmer the chicken. They’ll soak up the flavors and add a little variety.

What’s the best way to reheat leftovers?

For best results, reheat the chicken and gravy in a skillet over low heat, and the mashed potatoes in the microwave or stovetop with a splash of milk or cream to restore creaminess.
