High Protein Sheet Pan Chicken and Asparagus — Ready in 25 Minutes

Sheet pan dinners earn their reputation on nights like Tuesday — when you need something real on the table fast and the last thing you want is a pile of dishes. This high protein chicken and asparagus recipe is one of those weeknight dinners that looks like you tried harder than you did: golden chicken, tender-crisp asparagus, a little lemon. Done in under 30 minutes, start to table.

Why This Recipe Works

• One pan, almost no cleanup. Parchment liner means you're not scrubbing anything. Fold it up and done.
• Genuinely 25 minutes. Eight minutes of prep, 18 minutes in the oven. That's it.
• High protein without any effort. Chicken breast is doing the heavy lifting here — no protein powder, no tricks.
• Kid-friendly. The seasoning is savory but mild. Even picky eaters tend to eat this one, especially if you cut the asparagus into shorter pieces so it doesn't look so intimidating.
• Spring-ready. Asparagus is at its best from March through May — this is a good recipe to have in rotation right now.

Ingredients

• 1.75 lbs boneless skinless chicken breast, sliced into 1-inch strips
• 1 lb fresh asparagus, woody ends trimmed
• 3 tablespoons olive oil
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon smoked paprika
• ½ teaspoon kosher salt
• ½ teaspoon black pepper
• 1 lemon, half juiced and half sliced into rounds
• Optional: 2 tablespoons grated Parmesan for serving

Instructions

1. Preheat your oven to 425°F and line a large sheet pan with Reynolds parchment paper.
2. Pat the chicken strips dry with a paper towel, then place them in the center of the pan. Drizzle with 2 tablespoons of olive oil and season with garlic powder, onion powder, smoked paprika, salt, and pepper. Toss to coat evenly.
3. Arrange the asparagus spears around the chicken in a single layer. Drizzle with the remaining tablespoon of olive oil and season lightly with salt and pepper.
4. Lay the lemon rounds over the chicken and asparagus, then squeeze the remaining lemon half over the entire pan.
5. Roast at 425°F for 16-18 minutes, until the chicken is cooked through and golden at the edges and the asparagus tips are just starting to crisp. The chicken is done when it reads 165°F internally.
6. Let rest 2 minutes before serving. Finish with grated Parmesan if using.

One thing worth knowing: at 425°F, thicker chicken strips can lag behind. If yours are on the thicker side, give them a head start — pop the chicken in for 5 minutes before you add the asparagus. Asparagus goes from perfect to mushy fast, and you want that slight bite at the tips.

Tips and Substitutions

• Swap the protein. Boneless chicken thighs work well here and stay juicier — add 3-4 minutes to the cook time. Salmon fillets are another solid option; they'll be done in about 12-14 minutes at the same temp.
• Different vegetables. No asparagus? Broccolini, green beans, or halved Brussels sprouts all roast at the same rate. Zucchini and cherry tomatoes work too, though tomatoes will get saucy — not a bad thing.
• Make it dairy-free. Skip the Parmesan and finish with a drizzle of good olive oil and a pinch of flaky salt instead. Tastes just as good.
• Gluten-free as written. No modifications needed — this recipe is naturally gluten-free.
• Prep ahead. Slice the chicken and trim the asparagus the night before. Store them separately in the fridge. When you're ready to cook, it's literally just seasoning and a sheet pan.
• Leftovers. This reheats fine for lunch the next day, though the asparagus softens up a bit. If that bothers you, pack the chicken separately and add fresh greens instead.
