Step‑by‑Step Instructions for Oven-Roasted Cajun Chicken and Garlic Potatoes with Parmesan
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). Line a large baking sheet with parchment paper or foil to prevent sticking and make cleanup a breeze. This temperature ensures a crispy finish on both the Cajun chicken and garlic potatoes while retaining their juiciness during roasting.
Step 2: Prepare the Chicken and Potatoes
While the oven heats up, cube boneless chicken thighs or breasts into 1-inch pieces and quarter the baby red potatoes. In a large mixing bowl, combine the chicken and potatoes so they can soak up the flavors and spices before roasting. Ensure everything is cut to similar sizes for even cooking.
Step 3: Season the Mixture
Drizzle a generous amount of olive oil over the chicken and potatoes. Add minced garlic, Cajun seasoning, smoked paprika (if using), salt, and pepper. Use your hands or a spoon to thoroughly toss the ingredients, ensuring every piece is evenly coated with the flavorful seasoning to create that signature taste in your Oven-Roasted Cajun Chicken and Garlic Potatoes with Parmesan.
Step 4: Arrange on the Baking Sheet
Spread the seasoned chicken and potatoes in a single layer on the prepared baking sheet, making sure they have space between them to roast rather than steam. Scatter the mixture out evenly, allowing the hottest air to circulate and crisp everything up beautifully.
Step 5: Roast the Mixture
Place the baking sheet in the preheated oven and roast for 25-30 minutes. Halfway through, gently flip the chicken and potatoes with a spatula to promote even browning. You’re looking for the chicken to be cooked through (165°F internally) and the potatoes to turn a lovely golden brown.
Step 6: Add the Parmesan
Once roasted, remove the sheet from the oven and immediately sprinkle freshly grated Parmesan cheese over the hot chicken and potatoes. The heat will melt the cheese slightly, creating a deliciously rich layer. This finishing touch elevates your Oven-Roasted Cajun Chicken and Garlic Potatoes with Parmesan to a whole new level.
Step 7: Garnish and Serve
Finally, sprinkle chopped parsley over your dish for a pop of color and freshness. Serve the roasted Cajun chicken and garlic potatoes hot, enjoying each bite of juicy meat paired with crispy, cheesy potatoes. This comforting meal is perfect for sharing and brings warmth to your family table!

Make Ahead Options
These Oven-Roasted Cajun Chicken and Garlic Potatoes with Parmesan are a fantastic option for meal prep, saving you valuable time during busy weeknights! You can season and marinate the chicken and potatoes up to 24 hours in advance. Simply combine the cubed chicken, quartered potatoes, olive oil, garlic, and Cajun seasoning in a bowl, cover tightly, and refrigerate. This allows the flavors to meld beautifully. When you’re ready to serve, just spread the mixture on a baking sheet and roast as directed. To ensure quality and prevent drying out, consider adding the Parmesan just after roasting for that melty creaminess, ensuring a deliciously satisfying meal awaits.
