Crockpot Garlic Parmesan Chicken And Potatoes is the kind of dinner that earns a permanent spot in your rotation: you load the slow cooker in the morning, walk away, and come home to fork-tender chicken thighs and buttery gold potatoes swimming in a garlicky Parmesan sauce. The prep is about 15 minutes and most of that is cutting potatoes, so it fits even the most crowded Tuesday.

The trick to a sauce that tastes rich instead of watery is two small moves: pat the chicken dry and sear nothing at all, but stir in the Parmesan and a cornstarch slurry during the last 30 minutes. That gives you a glossy sauce that clings to the potatoes instead of pooling at the bottom of the crock.
This recipe serves 6 generously from a 6-quart slow cooker, and the leftovers reheat beautifully for lunch the next day. It is a complete one-pot meal, though a green vegetable on the side rounds it out nicely.
Why You'll Love This Recipe
About the Ingredients
2.5 lb (1.1 kg) boneless, skinless chicken thighs
Thighs stay moist through a long cook, unlike breast meat. If you only have chicken breasts, use them but check at 4 hours on low and pull them as soon as they hit 165F (74C).
2 lb (900 g) baby gold potatoes, halved or quartered if large
Baby gold or Yukon Gold potatoes hold their shape; russets turn mushy. Leave the skins on and scrub well, which saves time and adds texture.
1 medium yellow onion, cut into 1-inch wedges
Yellow onion melts into the sauce and adds sweetness. A red onion works but will tint the sauce pink; shallots are a milder swap.
8 garlic cloves, minced (about 3 tablespoons)
Fresh garlic is essential here; jarred garlic tastes flat after slow cooking. Mince it finely so it distributes evenly instead of clumping.
3 tablespoons unsalted butter, melted
Melted butter coats the potatoes so the seasoning sticks. Salted butter works too, but then reduce the added salt by half.
1/2 cup (120 ml) low-sodium chicken broth
Broth keeps the bottom of the crock from scorching before the chicken releases its juices. Vegetable broth or a splash of white wine plus water both work.
1 tablespoon cornstarch whisked into 2 tablespoons cold water
This slurry is what thickens the sauce at the end. Arrowroot powder works as a 1:1 swap if you avoid corn.
1 cup (90 g) finely grated Parmesan, plus more for serving
Grate it yourself from a block; pre-shredded Parmesan contains anti-caking starch and won't melt smoothly. Pecorino Romano is a sharper substitute.
1 teaspoon dried Italian seasoning
A blend of oregano, basil, and thyme. If you have only oregano, use 1/2 teaspoon oregano plus 1/2 teaspoon dried parsley.
1 teaspoon kosher salt and 1/2 teaspoon black pepper
Kosher salt is less dense than table salt, so measure accordingly. Taste the sauce before serving, since Parmesan brings its own salt.
2 tablespoons chopped fresh parsley, for garnish
Parsley adds a fresh finish against the rich sauce. Chopped chives or basil are good substitutes.
Tips & Tricks
Do Not Overcook the Chicken
Thighs are forgiving, but past 7 hours on low they shred into the sauce. Set a timer and pull them at 165F (74C) internal temperature.
Add Parmesan at the End
Stirring cheese in at the start makes it grainy and stringy. Add it in the last 30 minutes, off the heat, for a smooth sauce.
Cut Potatoes Evenly
Uniform 1-inch pieces cook at the same rate. Halve small potatoes and quarter any larger than a golf ball so nothing turns to mush.
Pro Tips
Step-by-Step Instructions
1. Prep the slow cooker
Lightly grease the insert of a 6-quart slow cooker with butter or nonstick spray. This prevents the potatoes from sticking and scorching during the long cook.
2. Season the chicken
Pat the chicken thighs dry with paper towels, then season both sides with the kosher salt, black pepper, and Italian seasoning. Set them aside while you cut the vegetables.
3. Build the layers
Scatter the halved potatoes and onion wedges in an even layer on the bottom of the crock. Nestle the seasoned chicken thighs on top in a single layer, then scatter the minced garlic over everything.
4. Add the liquid
Drizzle the melted butter over the chicken and potatoes, then pour the chicken broth down the side of the insert so it pools at the bottom. Do not stir, since you want the garlic to stay on top of the chicken.
5. Cook low and slow
Cover and cook on low for 6 hours or on high for 3.5 hours. The chicken is done when a thermometer inserted into the thickest thigh reads 165F (74C) and the potatoes slide off a fork easily.
6. Thicken the sauce
In a small bowl, whisk the cornstarch with 2 tablespoons cold water until smooth. Stir the slurry into the slow cooker, cover, and cook on high for 25 to 30 minutes, until the sauce bubbles at the edges and coats the back of a spoon.
7. Finish with Parmesan
Turn off the heat and stir in the grated Parmesan until it melts into a smooth, creamy sauce. Taste and adjust salt and pepper, keeping in mind the cheese is salty.
8. Serve
Spoon the chicken and potatoes into shallow bowls, ladle the garlic Parmesan sauce over the top, and finish with chopped parsley and extra Parmesan.
Delicious Variations
Creamy Garlic Parmesan
Stir 1/2 cup heavy cream in with the Parmesan at the end for a richer, gravy-like sauce that is excellent over rice.
Lemon Herb Twist
Add the zest of one lemon and 1 tablespoon fresh lemon juice with the Parmesan to brighten the sauce and cut the richness.
Spicy Parmesan
Add 1/2 teaspoon red pepper flakes with the garlic and finish with a pinch more for a gentle heat that balances the butter.
How to Store Crockpot Garlic Parmesan Chicken And Potatoes for Busy Weeknights
Refrigerator
Store leftovers in an airtight container in the refrigerator for up to 4 days. Keep the chicken and potatoes together with the sauce so they stay moist.
Freezer
Freeze in portioned containers for up to 2 months. The potatoes soften slightly on thawing, so this is best used for soups or hash rather than served whole.
Reheating
Reheat gently in a covered skillet over medium-low heat with a splash of broth, or microwave in 1-minute bursts, stirring between, until steaming hot. Avoid boiling, which tightens the chicken.
Frequently Asked Questions
Q: Can I use chicken breasts instead of thighs in the crockpot?
Yes, but reduce the cook time to about 4 hours on low because breasts dry out faster. Check them at 165F (74C) and remove them early if needed, then keep them warm while the potatoes finish.
Q: Why did my crockpot chicken and potatoes turn out watery?
The sauce is watery because the chicken releases liquid and the cornstarch was likely skipped or added too early. Stir the slurry in during the last 30 minutes and leave the lid off briefly to let excess steam escape.
Q: Can I put frozen chicken thighs in the slow cooker?
It is not recommended, because frozen chicken spends too long in the temperature danger zone and cooks unevenly. Thaw the thighs in the refrigerator overnight, which takes about 8 hours, before adding them to the crock.
Q: How long does garlic Parmesan chicken and potatoes take in the slow cooker?
Plan on 6 hours on low or 3.5 hours on high, plus 30 minutes to thicken the sauce. Total hands-on time is only about 15 minutes, so it fits a workday easily.
Q: Can I make this Crockpot garlic Parmesan chicken and potatoes dairy-free?
Yes, swap the butter for olive oil and use a dairy-free Parmesan alternative or nutritional yeast. The sauce will be slightly less rich but still garlicky and satisfying.
Load the slow cooker before you leave for work and come home to a garlicky, cheesy dinner that tastes like you spent the afternoon in the kitchen. If you make it, leave a rating below and tell me how your family liked it.
