When you need an easy dinner that’s filling, flavorful, and packed with protein, this High-Protein Garlic Parmesan Chicken & Potatoes recipe checks all the boxes. Juicy pieces of seasoned chicken breast roast alongside golden baby potatoes with plenty of fresh garlic, Parmesan, and herbs—all on one sheet pan.

The chicken develops lightly browned edges while staying tender inside, and the potatoes become crisp around the edges and creamy in the middle. Parmesan adds a salty, savory crust without turning the recipe into a heavy, creamy dish.

Best of all, each serving provides approximately 48 grams of protein, making this an excellent option for a satisfying weeknight dinner, meal prep, or anyone looking for an easy way to add more protein to dinner without relying on complicated ingredients.

Easy High-Protein Garlic Parmesan Chicken and Potatoes

High-protein dinners don’t have to mean plain chicken breast and steamed vegetables.

This recipe uses simple ingredients and a hot oven to turn chicken and potatoes into something you’d actually look forward to eating.

The trick is giving the potatoes a head start.

Potatoes take longer to roast than bite-size pieces of chicken breast. Instead of adding everything to the pan simultaneously and ending up with dry chicken or undercooked potatoes, the potatoes roast alone first.

While they’re cooking, the chicken is tossed with olive oil, fresh garlic, Parmesan, smoked paprika, Italian seasoning, salt, and black pepper.

The chicken then joins the partially roasted potatoes for the final portion of cooking.

You get crispy potatoes and juicy chicken without needing multiple pans.

A final sprinkle of Parmesan and fresh parsley adds plenty of flavor without covering everything in a heavy sauce.

🛒 Ingredients

Chicken Breast

Use 2 pounds boneless, skinless chicken breasts.

Chicken breast is the primary source of protein in this recipe. Cut it into relatively large 1½-inch pieces rather than tiny cubes.

Larger pieces are less likely to dry out while roasting.

Try to keep them reasonably similar in size, but they don’t need to be perfectly identical.

Baby Potatoes

Use 1½ pounds baby potatoes, halved or quartered depending on their size.

Baby gold potatoes work particularly well because they become creamy inside while developing crisp, browned edges.

If some potatoes are larger, quarter them.

Parmesan Cheese

Use ¾ cup freshly grated Parmesan, divided.

Parmesan adds salty, nutty flavor and helps create little browned, crispy areas on both the chicken and potatoes.

Freshly grated Parmesan generally melts and browns better than shelf-stable powdered cheese.

Fresh Garlic

Use 5 garlic cloves, finely minced.

Garlic is one of the main flavors, so fresh garlic works best.

Olive Oil

Use 3 tablespoons olive oil, divided.

The potatoes need enough oil to roast and brown properly, while a smaller amount coats the chicken and seasonings.

Italian Seasoning

Use 1½ teaspoons Italian seasoning.

This provides a simple blend of familiar herbs without requiring several separate dried seasonings.

Smoked Paprika

Use 1 teaspoon smoked paprika.

It adds warmth, color, and a subtle smoky flavor.

Regular paprika can be substituted.

Garlic Powder

Use 1 teaspoon garlic powder.

Even though we’re using fresh garlic, a little garlic powder gives the seasoning more even garlic flavor.

Onion Powder

Use ½ teaspoon onion powder.

Salt

Use approximately 1¼ teaspoons kosher salt, divided, or adjust to taste.

Remember that Parmesan is naturally salty.

Black Pepper

Use ¾ teaspoon freshly ground black pepper.

Fresh Parsley

Use approximately 2 tablespoons chopped fresh parsley for finishing.

It adds freshness and color to the roasted chicken and potatoes.

Lemon

Use ½ lemon, optional.

A small squeeze of fresh lemon juice immediately before serving brightens the garlic and Parmesan flavors.

👩‍🍳 How to Make High-Protein Garlic Parmesan Chicken & Potatoes

1. Preheat the oven

Preheat your oven to 425°F (220°C).

A hot oven is important for browning the potatoes rather than slowly steaming them.

2. Prepare the sheet pan

Line a large rimmed sheet pan with parchment paper for easier cleanup, or lightly grease the pan.

Don’t use a baking dish with high sides if you can avoid it. A wide sheet pan gives the ingredients more room to roast.

3. Prepare the potatoes

Wash and thoroughly dry the baby potatoes.

Cut small potatoes in half and larger ones into quarters.

4. Dry them well

Excess surface moisture can prevent browning.

Pat the cut potatoes dry if necessary.

5. Season the potatoes

Place the potatoes in a large mixing bowl.

Add:

• 2 tablespoons olive oil
• ½ teaspoon Italian seasoning
• ½ teaspoon garlic powder
• ½ teaspoon smoked paprika
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ¼ cup Parmesan

Toss thoroughly.

6. Arrange the potatoes

Spread the potatoes over the sheet pan in a single layer.

Position as many as possible with their cut sides facing down.

Don’t crowd them into a pile.

7. Start roasting

Roast the potatoes for 18–20 minutes before adding the chicken.

This head start is what allows the potatoes and chicken to finish around the same time.

8. Prepare the chicken

While the potatoes roast, pat the chicken breasts dry.

Cut them into approximately 1½-inch pieces.

9. Make the garlic Parmesan seasoning

In a large bowl, combine:

• Remaining 1 tablespoon olive oil
• Minced garlic
• Remaining 1 teaspoon Italian seasoning
• Remaining ½ teaspoon garlic powder
• Remaining ½ teaspoon smoked paprika
• Onion powder
• Remaining salt
• Remaining black pepper
• ⅓ cup Parmesan

10. Season the chicken

Add the chicken pieces and toss until evenly coated.

The chicken should have a light coating of oil, garlic, herbs, paprika, and Parmesan.

It should not be swimming in oil.

11. Remove the potatoes from the oven

After approximately 18–20 minutes, carefully remove the sheet pan.

The potatoes should have started softening and developing light golden color underneath.

12. Turn the potatoes

Use a spatula to turn or stir the potatoes.

13. Make room for the chicken

Push the potatoes toward one side and around the edges of the sheet pan.

Leave enough room for the chicken pieces to sit directly against the pan rather than on top of the potatoes.

14. Add the chicken

Arrange the seasoned raw chicken pieces across the open area of the sheet pan.

Keep them in a single layer.

This is the ideal preparation image stage: partially roasted potatoes + raw seasoned garlic-Parmesan chicken arranged on the sheet pan immediately before the final roast.

15. Return to the oven

Place the sheet pan back into the oven.

Roast for approximately 14–18 minutes.

16. Check the chicken

Cooking time will vary depending on the size of your chicken pieces.

Check the thickest pieces with an instant-read thermometer.

Chicken should reach 165°F (74°C).

17. Check the potatoes

Pierce one of the larger potato pieces with a fork.

It should be tender inside with golden, slightly crisp edges.

18. Add the remaining Parmesan

During the final few minutes, sprinkle the remaining Parmesan lightly over the chicken and potatoes.

19. Optional broil

For additional browning, broil the sheet pan for approximately 1–2 minutes.

Watch it closely because Parmesan can brown quickly.

20. Rest the chicken

Remove the pan from the oven and let everything rest for approximately 5 minutes.

21. Add fresh parsley

Scatter chopped parsley naturally over the chicken and potatoes.

22. Add lemon

If desired, squeeze a small amount of fresh lemon juice over the chicken.

Don’t use too much—you don’t want to make the potatoes soggy.

23. Taste and adjust

Taste a piece of chicken and potato.

Add a little additional salt or pepper if needed.

24. Serve

Divide the chicken and potatoes among plates while warm.

For an even more complete dinner, serve with roasted broccoli, green beans, asparagus, or a simple green salad.

✨ Variations

Garlic Parmesan Chicken & Broccoli

Add broccoli florets during the final 12–15 minutes of roasting.

Don’t add them at the beginning or they may become too dark.

Chicken and Sweet Potatoes

Replace the baby potatoes with approximately ¾-inch sweet potato cubes.

The flavor becomes slightly sweeter while still pairing well with garlic and Parmesan.

Spicy Garlic Parmesan Chicken

Add ¼–½ teaspoon crushed red pepper flakes to the chicken seasoning.

Cajun Chicken & Potatoes

Replace the Italian seasoning and paprika with your favorite Cajun seasoning.

Check its salt content before adding additional salt.

Garlic Parmesan Chicken & Green Beans

Add trimmed green beans during the final 12 minutes.

Herb Chicken & Potatoes

Add chopped fresh rosemary and thyme for a stronger herb flavor.

Extra High-Protein Version

Serve the chicken and potatoes with a high-protein side such as cottage cheese-based ranch dip or a simple Greek yogurt herb sauce.

🔥 Tips for the Best Garlic Parmesan Chicken & Potatoes

Give the potatoes a head start. This is the most important part of the recipe. Adding raw potatoes and chicken simultaneously can result in overcooked chicken before the potatoes are tender.

Cut the chicken into larger pieces. Tiny chicken cubes cook too quickly and can become dry.

Use a large sheet pan. Crowding creates steam instead of browning.

Dry the chicken. Seasonings adhere better to a dry surface.

Dry the potatoes too. Moisture works against crispy edges.

Place potatoes cut-side down. Direct contact with the hot pan encourages browning.

Use freshly grated Parmesan. It gives you better flavor and texture.

Don’t bury the chicken underneath the potatoes. Everything needs direct exposure to the oven’s heat.

Use a thermometer. Remove the chicken once the thickest pieces reach 165°F (74°C).

Broil only briefly. Garlic and Parmesan can burn quickly.

Add parsley after roasting. Fresh parsley provides better flavor and color when added at the end.

🥡 Storage, Reheating & Freezing

Refrigerator

Allow leftovers to cool before transferring them to an airtight container.

Refrigerate for up to 4 days.

This makes the recipe particularly useful for meal prep.

Reheating in the Oven

For the best texture, spread the chicken and potatoes over a baking sheet.

Reheat at 375°F (190°C) until warmed through.

The oven helps restore some crispness to the potatoes.

Air Fryer

Reheat individual portions at approximately 350°F (175°C) for a few minutes until hot.

This is another good option for restoring crisp edges.

Microwave

The microwave is the fastest option.

Reheat in short intervals until hot.

The chicken will remain tasty, although the potatoes will be softer.

Freezing

The cooked chicken can be frozen for up to 2–3 months.

The potatoes can also be frozen, although their texture will become softer after thawing.

For meal prep, I prefer refrigerating the complete dish and freezing only extra chicken when possible.

❓ High-Protein Chicken & Potatoes FAQs

How much protein is in this chicken and potatoes recipe?

Using 2 pounds of chicken breast and dividing the recipe into six servings provides roughly 45–50 grams of protein per serving, depending on the exact chicken and Parmesan used.

Is chicken and potatoes a good high-protein dinner?

Chicken breast is naturally protein-rich, while potatoes provide carbohydrates that make the meal more filling. Adding Parmesan contributes additional protein and flavor.

Can I use chicken thighs?

Yes. Boneless, skinless chicken thighs work, although the nutrition and cooking time will differ slightly.

Why do the potatoes cook before the chicken?

Potatoes require more cooking time. Giving them an 18–20 minute head start prevents the chicken from becoming dry while waiting for the potatoes to soften.

Can I add vegetables to the sheet pan?

Absolutely. Broccoli, green beans, asparagus, zucchini, and bell peppers can all work. Add quick-cooking vegetables later rather than at the beginning.

Can I meal prep this recipe?

Yes. Divide the cooked chicken and potatoes among meal-prep containers and refrigerate for up to four days.

How do I stop chicken breast from drying out?

Don’t cut it too small, avoid overcrowding the pan, and use an instant-read thermometer. Stop cooking once the thickest pieces reach 165°F (74°C).

Why aren’t my potatoes crispy?

The pan may be overcrowded, the potatoes may have been wet, or they may not have had enough direct contact with the hot sheet pan.

Can I use regular potatoes instead of baby potatoes?

Yes. Yukon Gold or red potatoes work well. Cut them into approximately 1-inch pieces so they cook at a similar rate.

Can I make this without Parmesan?

Yes, although it will no longer have the same garlic-Parmesan flavor. You may want to increase the herbs and adjust the salt.
