30-Minute Sheet Pan Gnocchi with Chicken & Pesto

Most gnocchi recipes start with a big pot of boiling water. This one starts with a hot oven. Shelf-stable gnocchi goes straight onto a sheet pan with 1-inch pieces of chicken, cherry tomatoes, red onion, and zucchini — no boiling, no draining, no stovetop. At 425°F the gnocchi roast up crisp and golden at the edges, the chicken cooks through to juicy 165°F, and the whole pan gets tossed with basil pesto and Parmesan while everything is still sizzling.

Why you’ll love it

• One pan, zero boiling. The gnocchi roast directly on the sheet pan — skipping the pot is the 30-minute enabler.
• Crispy, not chewy. High heat and a single layer give the gnocchi golden, crisped edges like tiny roast potatoes.
• ~40g protein per serving (estimated), thanks to chicken breast plus Parmesan.
• Weeknight-flexible. Swap in whatever vegetables are hanging around the crisper drawer.

Ingredients

• 1 1/4 lb boneless, skinless chicken breasts, cut into 1-inch pieces
• 1 (16 oz) package shelf-stable potato gnocchi
• 1 pint cherry tomatoes, halved
• 1 medium red onion, cut into thin wedges
• 1 medium zucchini, halved lengthwise and cut into 1/2-inch half-moons
• 3 tbsp olive oil, divided
• 1 1/4 tsp kosher salt, divided
• 1/2 tsp black pepper
• 1 tsp Italian seasoning
• 1/3 cup basil pesto
• 1/2 cup freshly grated Parmesan, plus more for serving
• 2 cups baby arugula or spinach
• Lemon wedges, for serving

Equipment

A large rimmed sheet pan (18×13-inch), parchment paper (optional, for easier cleanup), and an instant-read thermometer.

Instructions

1. Heat the oven (2 minutes). Position a rack in the center and preheat to 425°F (220°C). Line a large rimmed sheet pan with parchment if you like.
2. Season everything on the pan. Place the chicken pieces, gnocchi, cherry tomatoes, red onion, and zucchini on the sheet pan. Drizzle with 2 tablespoons of the olive oil and sprinkle with 1 teaspoon of the salt, the pepper, and the Italian seasoning. Toss well to coat.
3. Spread into a single layer (3 minutes). Arrange everything so the gnocchi and chicken sit in one uncrowded layer with a little space between pieces — crowding steams the gnocchi instead of crisping it.
4. Roast, first round (12 minutes). Roast for 12 minutes, until the gnocchi are set and just starting to crisp at the edges and the chicken is nearly cooked through.
5. Toss and finish (10 minutes). Drizzle the remaining 1 tablespoon of olive oil over the pan, toss everything so the other side browns, and roast 8–10 minutes more, until the gnocchi are golden and crisp and the chicken reads 165°F on an instant-read thermometer.
6. Pesto and Parmesan (2 minutes). Drop spoonfuls of the basil pesto over the hot pan and toss until every piece is glossy. Sprinkle with the Parmesan, scatter the arugula over the top, and serve right from the pan with lemon wedges and extra Parmesan.

Doneness cues: Chicken must reach 165°F internally. The gnocchi are done when the edges are golden-brown and crisp — they’ll look almost like little roasted potatoes. The tomatoes should be slumped and jammy.

Nutrition note

Protein is estimated at about 40g per serving, calculated from USDA FoodData Central values for the listed ingredients — this is an estimate, not a lab analysis. Actual values vary by brand and preparation.

Substitutions and tips

• Fresh or refrigerated gnocchi work the same way — no boiling needed. Frozen gnocchi can go on the pan straight from the freezer; add 3–4 minutes to the roast time.
• Pesto swap: sun-dried tomato pesto or a dollop of marinara both work in place of basil pesto.
• Vegetable options: swap the zucchini for bell peppers, broccoli florets, or asparagus. Keep the pieces similar in size so everything finishes together.
• Dairy-free: skip the Parmesan or use your favorite dairy-free shreds; finish with toasted pine nuts for richness.
• Don’t skip the single layer. If everything is crowded, the gnocchi steam instead of crisp — split between two pans if yours is small.

Storage and reheating

Refrigerate leftovers within 2 hours in an airtight container for up to 4 days. Reheat in a 400°F oven for 8–10 minutes to re-crisp, or microwave in 60-second bursts until steaming (165°F). Freezes well for up to 3 months — thaw overnight in the fridge. The gnocchi soften slightly after freezing but the pesto flavor holds.

Frequently asked questions

Do I really not have to boil the gnocchi first? Correct — that’s the whole trick. Shelf-stable potato gnocchi roast beautifully straight from the package, turning crisp at the edges like tiny roast potatoes.

How do I get the gnocchi crispy instead of chewy? Three things: a hot oven (425°F), a single uncrowded layer, and enough oil. If the pieces are piled up, the gnocchi steam instead of crisp.

Can I use fresh or frozen gnocchi? Yes to both. Fresh or refrigerated gnocchi roast in the same time. Frozen goes on the pan straight from the freezer — just add 3–4 minutes to the second roast.

Is this good for meal prep? Very — portion into containers with the arugula packed separately so it stays fresh. Reheat in the oven to re-crisp.
