How to Make Garlic Parmesan Crockpot Chicken and Potatoes:
Now that you have your ingredients ready, let’s dive into the steps for making this delightful Garlic Parmesan Crockpot Chicken and Potatoes. It’s as easy as pie, and I promise you’ll feel like a culinary superstar!
Step 1: Prepare the Chicken and Potatoes
Pat the chicken thighs completely dry with paper towels. This is a crucial step for getting a good sear and preventing the sauce from becoming watery. Season both sides of the chicken generously with salt, black pepper, Italian seasoning, and smoked paprika.
Step 2: Sear the Chicken (Optional but Highly Recommended)
Heat the tablespoon of olive oil in a large skillet over medium-high heat. Once hot, add the chicken thighs, working in batches if necessary to avoid overcrowding. Sear for 2-3 minutes per side, until a golden-brown crust forms. This step is not strictly mandatory, but it adds a tremendous depth of flavor (Maillard reaction) that boiling the chicken cannot achieve.
Step 3: Layer the Crockpot
Place the halved baby potatoes in the bottom of a 6-quart or larger slow cooker. Pour ½ cup of the chicken broth over the potatoes. Arrange the seared (or raw) chicken thighs on top of the potato layer.
Step 4: Create the Garlic Parmesan Sauce
In a medium bowl, whisk together the melted butter, 1/2 cup of grated Parmesan cheese, heavy cream, mayonnaise, minced garlic, dried parsley, dried oregano, onion powder, and optional red pepper flakes. Whisk until the sauce is completely smooth and well-emulsified.
Step 5: Pour and Cook
Pour the creamy garlic Parmesan sauce evenly over the chicken and potatoes in the slow cooker. Do not stir. Cover with the lid and cook on LOW for 6-7 hours or on HIGH for 3-4 hours. The dish is done when the chicken is cooked through (165°F / 74°C) and tender, and the potatoes are fork-tender.
Step 6: Thicken the Sauce
Once the cooking time is complete, carefully remove the chicken and potatoes from the crockpot and place them on a serving platter, tenting with foil to keep warm. You will be left with a delicious, but potentially thin, sauce in the pot. To thicken it, create a slurry by whisking the 2 tablespoons of cornstarch with 2 tablespoons of cold water in a small bowl until smooth. Turn the slow cooker to HIGH. Whisk the slurry into the sauce and let it cook, uncovered, for 10-15 minutes, whisking occasionally, until the sauce has thickened to a rich, gravy-like consistency.
Step 7: Combine, Garnish, and Serve
Return the chicken and potatoes to the crockpot and toss gently to coat in the newly thickened sauce. Alternatively, you can pour the sauce over the plated chicken and potatoes. Garnish generously with fresh grated Parmesan cheese and chopped fresh parsley before serving.
Tips for Success:
- Use Real Parmesan: For the best flavor and texture, use freshly grated Parmesan from a block or the pre-grated kind found in the refrigerated section. The shelf-stable canned powder does not melt well and can make the sauce grainy.
- Don’t Skip the Searing: The fond (browned bits) left in the skillet after searing the chicken is packed with flavor. Deglaze the skillet with the remaining ½ cup of chicken broth, scraping up the bits, and pour this liquid into the crockpot along with the potatoes.
- Choose the Right Potatoes: Waxy potatoes like baby gold, red, or Yukon Gold hold their shape beautifully during long cooking times. Avoid Russet potatoes, as they can become mushy.
- Prevent Curdling: To ensure your creamy sauce doesn’t break, use full-fat dairy products and avoid cooking on high heat for the entire duration if possible. Low and slow is best.
- Adjust Consistency: If your sauce is too thick after adding the slurry, thin it with a splash of chicken broth. If it’s too thin, create a bit more slurry and repeat the thickening process.

Equipment Needed:
- 6-Quart or Larger Slow Cooker
- Large Skillet (if searing)
- Mixing Bowls
- Whisk
- Measuring Cups and Spoons
Variations of Garlic Parmesan Crockpot Chicken and Potatoes:
- Chicken Breast Version: Use 2 lbs of boneless, skinless chicken breasts. Reduce cooking time to 4-5 hours on LOW or 2-3 hours on HIGH to prevent drying out.
- Creamy Garlic Parmesan Pasta: Omit the potatoes. Shred the cooked chicken and stir it back into the thickened sauce. Serve over cooked fettuccine, penne, or egg noodles.
- With Vegetables: Add 2 cups of broccoli florets or green beans to the slow cooker during the last 30 minutes of cooking for a complete veggie-packed meal.
- Lemon Garlic Parmesan: Add the zest of one lemon and 2 tablespoons of lemon juice to the sauce for a bright, fresh twist that cuts through the richness.
- Crispy Finish: For a golden top, transfer the cooked chicken, potatoes, and sauce to a baking dish, sprinkle with extra Parmesan and broil for 2-3 minutes until bubbly and spotted brown.
Serving Suggestions for Garlic Parmesan Crockpot Chicken and Potatoes:
- With Crusty Bread: A warm, crusty baguette or loaf of garlic bread is essential for sopping up every last drop of the incredible sauce.
- Over Rice or Cauliflower Rice: Serve the chicken, potatoes, and sauce over a bed of fluffy white rice or cauliflower rice for a different carb option.
- With a Simple Green Salad: A crisp side salad with a light vinaigrette provides a refreshing contrast to the rich, creamy main course.
- With Roasted Asparagus: A side of simply roasted asparagus spears drizzled with olive oil and lemon pairs beautifully.

FAQs about Garlic Parmesan Crockpot Chicken and Potatoes:
Q: Can I use chicken breasts instead of thighs?
A: Yes, but be cautious. Chicken breasts are leaner and can dry out more easily. Cook them for a shorter time (4-5 hours on LOW) and check for doneness early.
Q: My sauce is thin. What can I do?
A: The cornstarch slurry is the best solution. If it’s still too thin after one slurry, make a second one and repeat the process. Ensure you are whisking the slurry into the simmering liquid to activate the thickening power.
Q: Can I make this ahead of time?
A: You can assemble the entire dish in the crockpot insert the night before, cover, and refrigerate. In the morning, place the cold insert into the slow cooker base and you may need to add 30-60 minutes to the cooking time.
Q: Can I freeze the leftovers?
A: Yes, but the texture of the potatoes may become a bit softer upon reheating. Store in an airtight container for up to 3 months. Thaw in the refrigerator overnight and reheat gently on the stovetop or in the microwave.
Q: Why is my sauce grainy?
A: Graininess is usually caused by the cheese breaking. This can happen if the heat is too high or if you used a pre-grated cheese with anti-caking agents. Using fresh-grated Parmesan and cooking on LOW helps prevent this.
